IN CASE OF AN EMERGENCY

Lexus Link transceiver antenna

The Lexus Link transceiver antenna is removable. Before taking the vehicle to an automatic car wash, disconnect the antenna by unscrewing it from the body mount.

NOTICE If you forget reattaching the Lexus Link transceiver antenna, the Lexus Link System may not function properly.

IF YOU LOSE YOUR KEYS OR LOCK YOURSELF OUT

You can purchase a new key at your Lexus dealer if you can give them the key number and master key.

Even if you lose only one key, contact your Lexus dealer to make a new key. If you lose all your master keys, you cannot make new keys; the whole engine immobiliser system must be replaced.

See the suggestion given in “Keys” on page 8.

You can use the wireless remote control system with the new key. Contact your Lexus dealer for detailed information.

If your keys are locked in the vehicle and you cannot get a duplicate, many Lexus dealers can still open the door for you using special tools. If your vehicle is equipped with Lexus Link System, call the Lexus Link Call Center 1–800–25–LEXUS (Toll–Free) (1–800–255–3987). Once you provide the Lexus Link Call Center Advisor with your Lexus Link PIN (Personal Identification Number), or personal security word, they will unlock your vehicle.

IN CASE OF AN EMERGENCY

NOTICE

You must provide the Lexus Link operator with your Lexus Link PIN (Personal Identification Number ) or personal security word, before they lock/unlock your vehicle. However, the Lexus Link System will not be able to lock or unlock your vehicle if it has been parked for 48 hours or more after the ignition is turned off. Upon subscription expiration, all Lexus Link services (i.e. automatic notification, emergency call functions, service call functions) are deactivated.

If you must break a window to get in, we suggest breaking the smallest side window because it is the least expensive to replace. Be extremely cautious to avoid glass cuts.

MAINTENANCE REQUIREMENTS

Your Lexus vehicle has been designed for fewer maintenance requirements with longer service intervals to save both your time and money. However, each regular maintenance as well as day-to-day care is more important than ever before to ensure smooth, trouble-free, safe, and economical driving.

It is the owner’s responsibility to make sure the specified maintenance, including general maintenance services, is performed. Note that both the new vehicle and emission control system warranties specify that proper maintenance and care must be performed. See “Owner’s Guide”, “Owner’s Manual Supplement” or “Warranty Booklet” for complete warranty information.

General maintenance

General maintenance items are those day-to-day care practices that are important to your vehicle for proper operation. It is the owner’s responsibility to ensure that the general maintenance items are performed regularly.

These checks or inspections can be done either by yourself or your Lexus dealer.

Scheduled maintenance

The scheduled maintenance items listed in the “Owner’s Manual Supplement / Scheduled Maintenance” are those required to be serviced at regular intervals.

For details of your maintenance schedule, read the “Owner’s Manual Supplement / Scheduled Maintenance”.

It is recommended that only genuine Lexus parts be used for maintenance.

The owner may elect to use non-Lexus supplied parts for replacement purposes without invalidating the emission control system warranty. However, use of replacement parts which are not of equivalent quality may impair the effectiveness of the emission control systems.

You may also elect to have maintenance, replacement, or repair of the emission control devices and system performed by any automotive repair establishment or individual without invalidating this warranty. See “Owner’s Guide”, “Owner’s Manual Supplement” or “Warranty Booklet” for complete warranty information.

284

MAINTENANCE

Where to go for service? Lexus technicians are well-trained specialists and are kept up to date with the latest service information through technical bulletins, service tips, and in-dealership training programs. They are well informed about the operation of all the systems on your vehicle.

You can be confident that your Lexus dealer's service department performs the best job to meet the maintenance requirements of your vehicle.

Your copy of the repair order is proof that all required maintenance has been performed for warranty coverage. If any problems should arise with your vehicle while under warranty, your Lexus dealer will promptly take care of it. Again, be sure to keep a copy of the repair order for any service performed on your Lexus.

What about do-it-yourself maintenance? Many of the maintenance items are easy to do yourself, if you have a little mechanical ability and a few basic automotive tools. Simple instructions for how to perform them are presented in Section 6.

If you are a skilled do-it-yourself mechanic, the Lexus service manuals are recommended. Please be aware that do-it-yourself maintenance can affect your warranty coverage. See "Owner's Guide", "Owner's Manual Supplement" or "Warranty Booklet" for the details.

GENERAL MAINTENANCE Listed below are the general maintenance items that should be performed at the intervals specified. It is recommended that any problem you notice be brought to the attention of your Lexus dealer or qualified service shop for their advice.

CAUTION Make these checks only with adequate ventilation if you run the engine.

Vehicle exterior Items listed below should be performed from time to time, unless otherwise specified.

Tire pressure Check the pressure with a gauge every two weeks, or at least once a month and adjust as shown on the tire pressure label. See page 321 for additional information.

Tire surface Check the tires carefully for cuts, damage or excessive wear. See page 323 for additional information.

Wheel nuts When checking the tires, make sure to check the nuts for looseness. Tighten them if necessary.

MAINTENANCE

DOES YOUR VEHICLE NEED REPAIRING?

Be on the alert for changes in performance and sounds, and visual tip-offs that indicate service is needed. Some important clues are:

• Engine missing, stumbling, or pinging
• Appreciable loss of power
• Strange engine noises
• A fluid leak under the vehicle (However, water dripping from the air conditioning after use is normal.)
• Change in exhaust sound (This may indicate a dangerous carbon monoxide leak. Drive with the windows open and have the exhaust system checked immediately.)
• Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
• Vehicle pulls to one side when driving straight on a level road
• Strange noises related to suspension movement
• Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches floors, vehicle pulls to one side when braking
• Engine coolant temperature continually higher than normal

If you notice any of these clues, take your vehicle to your Lexus dealer as soon as possible. It probably needs adjustment or repair.

CAUTION

Do not continue driving with the vehicle unchecked. It could result in serious vehicle damage and possibly personal injury.

288

MAINTENANCE

EMISSION INSPECTION AND MAINTENANCE (I/M) PROGRAMS

Some states have vehicle emission inspection programs which include OBD (On-Board Diagnostics) checks.

The OBD system monitors the operation of the emission control system. When the OBD system determines that a problem exists somewhere in the emission control system, the malfunction indicator lamp comes on. In this case, your vehicle may not pass the I/M test and need to be repaired. Contact your Lexus dealer to service the vehicle.

Even if the malfunction indicator lamp does not come on, your vehicle may not pass the I/M test as readiness codes have not been set in the OBD system.

Readiness codes are automatically set during ordinary driving. However, when the battery is disconnected or run down, the codes are erased. Also, depending on your driving habits, the codes may not be completely set.

Also, if the malfunction indicator lamp had come on recently due to temporary malfunction such as a loose fuel tank cap, your vehicle may not pass the I/M test.

The malfunction indicator lamp will go off after taking several driving trips, but the error code in the OBD system will not be cleared unless about 40 trips or more are taken.

If your vehicle does not pass the I/M test and the malfunction indicator lamp does not come on, contact your Lexus dealer to prepare the vehicle for re-testing.

INTRODUCTION

DO-IT-YOURSELF SERVICE PRECAUTIONS

If you perform maintenance yourself, be sure to follow the correct procedure given in this Section.

You should be aware that improper or incomplete servicing may result in operating problems.

Performing do-it-yourself maintenance during the warranty period may affect your warranty coverage. Read the separate Lexus Warranty statement for details and suggestions.

This Section gives instructions only for those items that are relatively easy for an owner to perform. As explained in Section 5, there are still a number of items that must be performed by a qualified technician with special tools.

For information on tools and parts for do-it-yourself maintenance, see "Parts and tools" on page 296.

Utmost care should be taken when working on your vehicle to prevent accidental injury. Here are a few precautions that you should be especially careful to observe:

CAUTION

• When the engine is running, keep hands, clothing, and tools away from the moving fan and engine drive belt. (Removing rings, watches, and ties is advisable.)

• Right after driving, the engine compartment – the engine, radiator, exhaust manifold and power steering fluid reservoir, etc. – will be hot. So be careful not to touch them. Oil and other fluids may also be hot.

• Do not smoke, cause sparks or allow open flames near fuel or the battery. Their fumes are flammable.

• Do not get under your vehicle with just the body jack supporting it. Always use automotive jack stands or other solid supports.

• Be sure the ignition is off if you work near the electric cooling fan or radiator grille. With the ignition on, the electric cooling fan may automatically start to run if the air conditioning is on and/or if the coolant temperature is high.

• Use eye protection whenever you work on or under your vehicle where you may be exposed to flying or falling material, fluid spray, etc.

• Be extremely cautious when working on the battery. It contains poisonous and corrosive sulfuric acid.

• Warning: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

294

INTRODUCTION

NOTICE

• Remember that battery and ignition cables carry high currents or voltages. Be careful of accidentally causing a short circuit.
• Before closing the engine hood, check to see that you have not forgotten any tools, rags, etc.
• Do not drive with the air cleaner removed, or excessive engine wear could result. Also backfiring could cause a fire in the engine compartment.
• Do not overfill automatic transmission fluid, or the transmission could be damaged.
• Be careful not to scratch the glass surface with the wiper frame.

POSITIONING THE JACK

►Front

►Rear

When jacking up your vehicle with the jack, position the jack correctly as shown in the illustrations.

295

INTRODUCTION

CAUTION When jacking, be sure to observe the following to reduce the possibility of personal injury:

• Follow jacking instructions.
• Do not put any part of your body under the vehicle supported by the jack. Personal injury may occur.
• Do not start or run the engine while your vehicle is supported by the jack.
• Stop the vehicle on a level firm ground, firmly set the parking brake and put the transmission in “P”.
• Make sure to set the jack properly in the jack point. Raising the vehicle with jack improperly positioned will damage the vehicle or may allow the vehicle to fall off the jack and cause personal injury.
• Never get under the vehicle when the vehicle is supported by the jack alone; use vehicle support stands.
• Do not raise the vehicle with someone in the vehicle
• When raising the vehicle, do not place any objects on top of or underneath the jack.

NOTICE Make sure to place the jack correctly, or your vehicle may be damaged.
