왔 Replacing bulbs Safe vehicle operation depends on proper exterior lighting and signaling. It is there- fore essential that all bulbs and lamp as- semblies 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 your autho- rized Mercedes-Benz Center for headlamp adjustment.

Notes on bulb replacement
Warning!
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al- low the lamp to cool down before changing a bulb.
Halogen lamps contain pressurized gas. A bulb can explode if you: 앫 touch or move it when hot 앫 drop the bulb 앫 scratch the bulb Wear eye and hand protection.
Because of high voltage in Bi-Xenon* lamps, it is dangerous to replace the bulb or repair the lamp and its components. We recom- mend that you have such work done by a qualified technician.
앫 Use only 12 volt bulbs of the same type
and with the specified watt rating.
앫 Switch lights off before changing a bulb
to prevent short circuits.
앫 Always use a clean lint-free cloth when
handling bulbs.
앫 Your hands should be dry and free of oil
and grease.
앫 If the newly installed bulb does not light up, visit an authorized Mercedes-Benz Center.
앫 Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized Mercedes-Benz Center: 앫 Additional turn signal lamps in the

왘 Fold the wiper arm backward to rest on the windshield. Make sure you hold on to the wiper when folding the wiper arm back.
Never open the hood when the wiper arm is folded forward. Hold on to the wiper when folding the wiper arm back. If released, the force of the impact from the tensioning spring could crack the windshield. Do not allow the wiper arms to contact the windshield glass without a wiper blade inserted. Make certain that the wiper blades are properly installed. Improperly installed wiper blades may cause windshield damage. For your convenience, we recommend that you have this work carried out by an authorized Mercedes-Benz Center.

Warning!
The dimensions of the Minispare wheel and the collapsible tire are different from those of the road wheels. As a result, the vehicle handling characteristics change when driv- ing with a spare wheel mounted.
The spare wheel should only be used tempo- rarily, and replaced with a regular road wheel as quickly as possible.
In the case of a flat tire, you may tempo- rarily use the spare wheel when observing the following restrictions: 앫 Do not exceed a vehicle speed of
50 mph (80 km/h).
앫 Drive to the nearest tire repair facility
to have the flat tire repaired or re- placed as appropriate.
앫 Do not operate vehicle with more than
one spare wheel mounted.

Preparing the vehicle
Mounting the spare wheel
왘 Park the vehicle as far as possible from
moving traffic on a hard surface.
왘 Turn on the hazard warning flashers. 왘 Engage the steering wheel lock in the
straight-ahead position and set the parking brake.
왘 Move the selector lever to P. 왘 Have any passenger exit the vehicle at
a safe distance from the roadway.
Preparing the vehicle Prepare the vehicle as described under “Preparing the vehicle” on this page. 왘 Take the spare wheel out of the trunk
(컄 page 356).
왘 Take the wheel wrench and the jack
out of the trunk (컄 page 358).
Lifting the vehicle 왘 Prevent the vehicle from rolling away by blocking wheels with wheel chocks (not included) or other sizable objects.
When changing wheel on a level surface: 왘 Place one chock in front of and one be- hind the wheel that is diagonally oppo- site to the wheel being changed.
When changing wheel on a hill: 왘 Place chocks on the downhill side
blocking both wheels of the other axle.
Warning!
The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into either side 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

Warning!
Removing the wheel
Position the jack only on the jack take-up brackets designed for this purpose. If the jack is not properly positioned, the ve- hicle may slip off of the jack.
Warning!
The jack is intended only for lifting the vehi- cle briefly for wheel changes. It is not suited for performing maintenance work under the vehicle. Never lie down under the raised ve- hicle. Do not start the engine when the vehi- cle is raised.
1 Alignment bolt 왘 Unscrew the upper-most wheel bolt
and remove.
왘 Replace this wheel bolt with alignment
bolt 1 supplied in the tool kit.
왘 Remove the remaining bolts.

Do not tighten the wheel bolts when the ve- hicle is raised. Otherwise the vehicle could tip over.
Always replace wheel bolts that are dam- aged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be re- paired immediately. Do not continue to drive under these circumstances! Contact an au- thorized Mercedes-Benz Center or call Roadside Assistance.
Incorrect wheel bolts or improperly tight- ened wheel bolts can cause the wheel to come off. This could cause an accident. Be sure to use the correct wheel bolts.
