GAUGES, METERS AND SERVICE REMINDER INDICATORS

FUEL GAUGE

Low fuel level warning light

The gauge indicates the approximate quantity of fuel remaining in the tank when the ignition switch is on.

It is a good idea to keep the tank over 1/4 full.

If the fuel level approaches "E" or the low fuel level warning light comes on, fill the fuel tank as soon as possible.

On inclines or curves, due to the movement of fuel in the tank, the fuel gauge needle may fluctuate or the low fuel level warning light may come on earlier than usual.

If the fuel tank is completely empty, the malfunction indicator lamp comes on. Fill the fuel tank immediately.

The indicator lamp goes off after driving several times. If the indicator lamp does not go off, contact your Lexus dealer as soon as possible.

It is not a malfunction even if the needle of the fuel gauge returns to "E" when the ignition switch is turned to the "START" position.

See the inner back cover for fuel capacity and recommended fuel selection.

ENGINE COOLANT TEMPERATURE GAUGE

Normal range

The gauge indicates the engine coolant temperature when the ignition switch is on. The engine operating temperature will vary with changes in weather and engine load.

If the needle points to the red zone or higher, stop your vehicle and allow the engine to cool.

44

GAUGES, METERS AND SERVICE REMINDER INDICATORS

Your vehicle may overheat during severe operating conditions, such as:

• Driving up a long hill on a hot day.
• Reducing speed or stopping after high speed driving.
• Idling for a long period with the air conditioning on in stop-and-go traffic.
• Towing a trailer.

It is not a malfunction even if the needle of the engine coolant temperature gauge returns to “C” when the ignition switch is turned to the “START” position.

NOTICE

• Do not remove the thermostat in the engine cooling system as this may cause the engine to overheat. The thermostat is designed to control the flow of coolant to keep the temperature of the engine within the specified operating range.
• Do not continue driving with an overheated engine. See "If your vehicle overheats" on page 297.

ENGINE OIL PRESSURE GAUGE

► 1 Normal driving 2 Idling

The engine oil pressure gauge indicates engine oil pressure when the ignition is on. Check it while driving to make sure the needle is in the proper range.

If the engine oil pressure should stay below the normal range, pull off the road to a safe place and stop the engine immediately. Call a Lexus dealer or qualified repair shop for assistance.

Engine oil pressure may not build up when the engine oil level is too low. The engine oil pressure gauge is not designed to indicate engine oil level, and the engine oil level must be checked using the level dipstick.

It is not a malfunction even if the needle of the engine oil pressure gauge returns to “L” when the ignition switch is turned to the “START” position.

45

GAUGES, METERS AND SERVICE REMINDER INDICATORS

NOTICE Do not drive the vehicle with the engine oil pressure below the normal range until the cause is fixed – it may ruin the engine.

VOLTMETER

▶ 1 Normal range 2 Discharge warning light

The voltmeter tells whether the battery is charged or discharged. Check it while the engine is running – the needle should always indicate as shown above.

If the needle reads below or above the normal range while the engine is running, it indicates the charging system needs immediate repair.

However, it is normal for the needle to drop below the normal range during engine starting.

It is not a malfunction even if the needle of the volt meter returns to “9” when the ignition switch is turned to the “START” position.

46

GAUGES, METERS AND SERVICE REMINDER INDICATORS

TACHOMETER

The tachometer indicates engine speed in thousands of rpm (revolutions per minute). Use it while driving to prevent engine over-revving.

Driving with the engine running too fast causes excessive engine wear and poor fuel economy. Remember, in most cases the slower the engine speed, the greater the fuel economy.

It is not a malfunction if the needle of the tachometer returns to "0" when the ignition switch is turned to the "START" position.

NOTICE Do not let the indicator needle get into the red zone. This may cause severe engine damage.

ODOMETER AND TRIP METER

► "ODO/TRIP" knob

This meter displays the odometer and two trip meters. To change the mode indication, push the "ODO/TRIP" knob briefly. Each time you push the knob, the mode changes in order from the odometer to trip meter A to trip meter B, then back to the odometer, etc.

The odometer records the total distance the vehicle has been driven. The twin trip meter records two different distances independently.

For example, you can use one meter to calculate the fuel economy and the other to measure the distance on each trip.

To set the A trip meter to zero, display the A meter reading, push the knob and hold it. The same applies for the B trip meter.

The data of trip meters will be cancelled if the electrical power source is disconnected.

SERVICE REMINDER INDICATORS AND WARNING BUZZERS

48

GAUGES, METERS AND SERVICE REMINDER INDICATORS

49

GAUGES, METERS AND SERVICE REMINDER INDICATORS

(a) Brake System Warning Light and Buzzer This light comes on in the following cases when the ignition key is in the “ON” position. ● When the parking brake is applied ... This light comes on for a few seconds when the ignition key is in the “ON” position even after the parking brake is released. ● When the brake fluid level is low ...

CAUTION It is dangerous to continue driving normally when the brake fluid level is low.

● When the hydraulic brake booster fails ... If the hydraulic booster causes a problem resulting in poor braking performance, the warning light comes on and buzzer sounds continuously. Have your vehicle checked at your Lexus dealer in the following cases: ● The light does not come on even if the parking brake is applied when the ignition key is in the “ON” position. ● The light does not come on even if the ignition key is turned on with the parking brake released. A warning light turning on briefly during operation does not indicate a problem.

CAUTION If any of the following conditions occurs, immediately stop your vehicle at a safe place and contact your Lexus dealer. ● The light does not turn off even after the parking brake is released while the engine is running. ● The warning buzzer comes on together with the warning light. In either case, this can indicate that the brakes may not work properly and your stopping distance will become longer. Depress the brake pedal firmly and bring the vehicle to an immediate stop. ● The brake system warning light remains on together with the “ABS” warning light. In this case, not only the anti-lock brake system will fail, but also the vehicle will become extremely unstable during braking.

50

GAUGES, METERS AND SERVICE REMINDER INDICATORS

Any of the following conditions may occur, but do not indicate the malfunction:

• The light may stay on for about 60 seconds after the ignition key is turned to the “ON” position. It is normal if it turns off after a while.
• Depressing the brake pedal repeatedly may turn on the warning light and buzzer. It is normal if the light turns off and the buzzer stops sounding after a few seconds.
• You may hear a small sound in the engine compartment after the engine is started or the brake pedal is depressed repeatedly. This is a pump pulsating sound of the brake system, and it is not a malfunction.

(b) Driver’s Seat Belt Reminder Light and Buzzer

This light and buzzer remind you to buckle up the driver’s seat belt.

Once the ignition key is turned to "ON" or "START", the reminder light flashes and buzzer sounds if the driver’s seat belt is not fastened. Unless the driver fastens the belt, the light stays flashing and the buzzer stops after about 4 to 8 seconds.

(c) Front Passenger’s Seat Belt Reminder Light

This light reminds you to buckle up the front passenger’s seat belt.

Once the ignition key is turned to "ON" or "START", the reminder light flashes if a passenger sits in the front passenger seat and does not fasten the seat belt. Unless the front passenger fastens the belt, the light stays flashing.

If luggage or other load is placed on the front passenger seat, depending on its weight and how it is placed on the seat, built-in sensors in the seat cushion may detect the pressure, causing the reminder light to come on.

51

GAUGES, METERS AND SERVICE REMINDER INDICATORS

(d) SRS Warning Light The indicator comes on when the ignition key is turned to the “ON” position. It goes off after about 6 seconds. This means the SRS airbags and front seat belt pretensioners are operating properly.

The SRS warning light system monitors the airbag sensor assembly, front airbag sensors, side and curtain shield airbag sensor assemblies, curtain shield airbag sensor assemblies, driver’s seat position sensor, driver’s seat belt buckle switch, inflators, seat belt pretensioners, warning light, interconnecting wiring and power sources.

If either of the following conditions occurs, this indicates a malfunction somewhere in the components monitored by the warning light system. Contact your Lexus dealer as soon as possible to service the vehicle.

• When the ignition key is turned to the “ON” position, the light does not come on, remains on or flashes.
• The light comes on or starts flashing while driving.

If the light stays on, it indicates that the driver and passenger airbags have a problem. If the light flashes, the side and curtain shield airbags and/or the seat belt pretensioners have a problem.

(e) Engine Oil Replacement Reminder Light (U.S.A. only) This light reminds you when to replace the engine oil.

This light will come on when the ignition key is turned to “ON” and will go off after about a few seconds.

When you drive for about 8000 km (5000 miles) after the engine oil replacement, this light illuminates for about 3 seconds and then flashes for about 12 seconds with the ignition key turned to “ON” position. If you continue driving without the engine oil replacement, and if the driving range exceeds 12000 km (7500 miles), the light will come on after the ignition key is turned to “ON” position. The light will remain on thereafter.

If the light is flashing, we recommend that you replace the engine oil at an early opportunity depending on the driving and road condition. If the light comes on, replace it as soon as possible.

You need to reset the light after the engine oil replacement. Reset the light by following the procedure below:

1. Turn the ignition key to the “OFF” position with the odometer reading shown. (For details, see “Odometer and trip meter” on page 47.)
2. Turn the ignition key to the “ON” position while holding down the “ODO/TRIP” knob.

Hold down the knob until the light goes off. Before the light goes off, it illuminates for 3 seconds, flashes for 2 seconds and illuminates for 1 second.

52

GAUGES, METERS AND SERVICE REMINDER INDICATORS

If the system fails to reset, the light will remain flashing. In this case, return to step 1 and try again.

(f) Malfunction Indicator Lamp

This lamp comes on when the ignition key is turned to the “ON” position and goes off after the engine starts. This means that the warning light system is operating properly.

If the lamp remains on, or the lamp comes on while driving, first check the following:

● Empty fuel tank If the fuel tank is empty, refuel immediately.

● Loose fuel tank cap If the fuel tank cap is loose, securely tighten it.

These cases are temporary malfunctions. The malfunction indicator lamp will go off after taking several driving trips.

If the lamp will not go off even after several trips, contact your Lexus dealer as soon as possible.

If the fuel tank is not empty or the fuel tank cap is not loose...

● There is a problem somewhere in the engine, emission control system, electronic throttle control system, automatic transmission electrical system or warning light system itself.

Contact your Lexus dealer as soon as possible to service the vehicle.

If this lamp comes on and the engine speed does not increase with the accelerator pedal depressed, there may be a problem somewhere in your electronic throttle control system.

At this time, vibration may occur. However, if you depress the accelerator pedal more firmly and slowly, you can drive your vehicle at low speeds. Have your Lexus checked by your Lexus dealer as soon as possible.

Even if the abnormality of the electronic throttle control system is corrected during low speed driving, the system may not be recovered until the engine is stopped and the ignition key is turned to “ACC” or “LOCK” position.

CAUTION

Be especially careful to prevent erroneous pedal operation.

Emissions inspection and maintenance (I/M) programs

Your vehicle may not pass a state emission inspection if the malfunction indicator lamp remains on. Contact your Lexus dealer to check your vehicle’s emission control system and OBD (On-Board Diagnostics) system before taking your vehicle for the inspection.

For details, see “Emissions inspection and maintenance (I/M) programs” on page 334.

53

GAUGES, METERS AND SERVICE REMINDER INDICATORS

(g) “ABS” Warning Light

The light comes on when the ignition key is turned to the “ON” position. If the anti-lock brake system and the brake assist system work properly, the light turns off after a few seconds. Thereafter, if either of the systems malfunctions, the light comes on again.

When the “ABS” warning light is on (and the brake system warning light is off), the anti-lock brake system, the brake assist system, the active traction control system and/or the vehicle stability control system do/does not operate, but the brake system still operates conventionally.

When the “ABS” warning light is on (and the brake system warning light is off), the anti-lock brake system does not operate so that the wheels could lock up during a sudden braking or braking on slippery road surfaces.

If either of the following conditions occurs, this indicates a malfunction somewhere in the components monitored by the warning light system. Contact your Lexus dealer as soon as possible to service the vehicle.

• The light does not come on when the ignition key is turned to the “ON” position or remains on.
• The light comes on while you are driving.

A warning light turning on briefly during operation does not indicate a problem.

CAUTION

If the “ABS” warning light remains on together with the brake system warning light, immediately stop your vehicle at a safe place and contact your Lexus dealer.

In this case, not only the anti-lock brake system will fail but also the vehicle will become extremely unstable during braking.

Either of the following conditions may occur, but do not indicate the malfunction:

• The light may stay on for about 60 seconds after the ignition key is turned to the “ON” position. It is normal if it turns off after a while.
• Depressing the brake pedal repeatedly may turn on the light. It is normal if it turns off after a few seconds.

(h) Open Door Warning Light

This light remains on until all the side doors and back door are completely closed.

54

GAUGES, METERS AND SERVICE REMINDER INDICATORS

(i) Rear Light Failure Warning Light If this light comes on when the headlight switch is turned on (at the first or second clickstop), it indicates that one or more tail lights are burned out. If it comes on when the brake pedal is depressed, one or more stop lights are burned out. Have defective bulbs replaced as soon as possible.

(j) Unengaged "Park" Warning Light This light warns that the transmission "Park" mechanism is not engaged. If the four-wheel drive control is in the "N" position while the selector lever is in the "P" position, the transmission will disengage and the wheels will not lock.

CAUTION To restore the park function, shift the four-wheel drive control out of "N".

(k) Automatic Transmission Fluid Temperature Warning Light This light warns that the automatic transmission fluid temperature is too high. If this light comes on while you are driving, slow down and pull off the road. Stop the vehicle at a safe place and put the selector lever in "P" and leave the engine idling until the light goes off. If the light goes off, you can start the vehicle again. If the light does not go off, call a Lexus dealer or qualified repair shop for assistance.

NOTICE Continued driving with the warning light on may damage the automatic transmission.

55

GAUGES, METERS AND SERVICE REMINDER INDICATORS

(l) Vehicle Stability Control System and Active Traction Control System Warning Light

This light warns that there is a problem somewhere in the vehicle stability control system and active traction control system.

If the “VSC/TRAC” warning light and “VSC OFF” indicator light come on, have your vehicle checked by Lexus dealer as soon as possible. However, it is no problem that the “VSC/TRAC” warning light comes on when the brake actuator temperature becomes high. (For details, see “Active traction control system” on page 259.)

The lights will stay on with the ignition key turned to “ON”, and will go off after about a few seconds.

The lights may stay on for 60 seconds after the ignition key is turned to the “ON” position. It is normal if they go out after a while.

Depressing the brake pedal repeatedly may turn on the lights. It is normal if they go out after a few seconds.

When the “VSC/TRAC” warning light and “VSC OFF” indicator light come on, the vehicle stability control system and/or active traction control system do not operate, but there is no problem to continue your driving.

(m) Variable Gear Ratio Steering System Warning Light

This light warns that there is a problem somewhere in the variable gear ratio steering system.

The light will come on when the ignition key is turned to “ON” and will go off after a few seconds.

If the light comes on while driving, the system is not working. Although conventional steering operates when maneuvered, a larger degree of wheel maneuvering (than at the time when the system is functioning properly) is needed when driving at low speed. At this time, the center position of the steering wheel could be changed. Although it is no problem to continue driving, have your vehicle repaired at your Lexus dealer.

In the following cases, contact your Lexus dealer:

• The warning light does not come on after the ignition key is turned to “ON”.

• The warning light remains on after the ignition key is turned to “ON”.

• The warning light comes on while driving.

The light will flash if you disconnect and reconnect the battery terminal. This is because the system is reset temporarily. However, it is no problem to drive. To turn off the light, drive for a short while. The system will be set automatically and return to normal.

56

(n) Lexus Night View System Warning Light When this light comes on, the bulb for the near-infrared floodlight (night view projector) is burned out. Have it replaced at Lexus dealer.

(o) Discharge Warning Light This light warns that the battery is being discharged. If it comes on while you are driving, stop the vehicle, turn off the engine, and check for the cause. Look first at the engine drive belt.

• If it is loose or broken, the generator will not charge the battery properly.
• If the belt is O.K., there is a problem somewhere in the charging system.

The engine ignition will continue to operate, however, until the battery is discharged. Turn off the air conditioning, blower, radio, etc., and drive directly to the nearest Lexus dealer or repair shop.

NOTICE Do not continue driving if the engine drive belt is broken or loose.

(p) Low Fuel Level Warning Light This light comes on when the fuel level in the tank becomes very low. Fill the tank as soon as possible. On inclines or curves, due to the movement of fuel in the tank, the low fuel level warning light may come on earlier than usual.

(q) Low Washer Fluid Warning Light This light comes on when the fluid level in the tank becomes very low. Fill the tank as soon as possible.

(r) Key Reminder Buzzer This buzzer reminds you to remove the key when you open the driver's door with the ignition key in the "ACC" or "LOCK" position.
