Vehicle jack

Warning!

The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into both sides of the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always firmly set parking brake and block wheels before raising vehicle with jack.

Do not disengage parking brake while the vehicle is raised. Be certain that the jack is always vertical (plumb line) when in use, especially on hills. Always try to use the jack on level surface. Make sure the jack arm is fully seated in the jack take-up bracket. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle.

The vehicle jack is located in the storage compartment underneath the trunk floor.

Warning!

The dimensions of the Minispare wheel are different from those of the road wheels. As a result, the vehicle handling characteristics change when driving with a Minispare wheel mounted.

The Minispare wheel should only be used temporarily, and should be replaced with a regular road wheel as quickly as possible.

Practical hints

Where will I find ...?

In case of a flat tire, you may temporarily use the Minispare wheel when observing the following restrictions:

• Do not exceed a vehicle speed of 50 mph (80 km/h).
• Drive to the nearest tire repair facility to have the flat tire repaired or replaced as appropriate.
• Do not operate vehicle with more than one Minispare wheel mounted.

For more information, see “Rims and Tires” (▷ page 432).

Replacing bulbs

▼ Replacing bulbs

Safe vehicle operation depends on proper exterior lighting and signaling. It is therefore essential that all bulbs and lamp assemblies are in good working order at all times.

Correct headlamp adjustment is extremely important. Have headlamps checked and readjusted at regular intervals and when a bulb has been replaced. See an authorized Mercedes-Benz Center for headlamp adjustment.

If the headlamps or front fog lamps are fogged up on the inside as a result of high humidity, driving the vehicle a distance with the lights on should clear up the fogging.

Substitute bulbs will be brought into use when lamps malfunction. Observe the messages in the multifunction display (▷ page 377).

Replacing bulbs

Bulbs

Front lamps

¹ Vehicles with Bi-Xenon* headlamps: Low beam and high beam use the same D2S-35W lamp. Do not replace the Xenon bulbs yourself. Contact an authorized Mercedes-Benz Center.

398

Rear lamps

Warning!

Bulbs and bulb sockets can be very hot. Allow the lamp to cool down before changing a bulb.

Keep bulbs out of reach of children.

Halogen lamps contain pressurized gas. A bulb can explode if you

• touch or move it when hot
• drop the bulb
• scratch the bulb

Wear eye and hand protection.

Because of high voltage in Xenon lamps, it is dangerous to replace the bulb or repair the lamp and its components. We recommend that you have such work done by a qualified technician.

Practical hints

Replacing bulbs

Notes on bulb replacement

• Only use 12 volt bulbs of the same type and with the specified watt rating.
• Switch lights off before changing a bulb to prevent short circuits.
• Always use a clean lint-free cloth when handling bulbs.
• Your hands should be dry and free of oil and grease.
• If the newly installed bulb does not come on, visit an authorized Mercedes-Benz Center.
