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

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.

Replacing bulbs
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 an authorized
Mercedes-Benz Center for headlamp ad-
justment.
i
If the headlamps or front fog lamps are
fogged up on the inside as a result of high humid-
ity, driving the vehicle a distance with the lights
on should clear up the fogging.
i
Substitute bulbs will be brought into use
when the following lamps malfunction:


Brake lamps


Rear fog lamps


Front parking lamps


Tail lamps


Turn signal lamps
Observe the messages in the multifunction dis-
play (page 557).

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.
Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center.


the Bi-Xenon lamps


the front turn signal lamps


the front fog lamps


the additional turn signal lamps in the
exterior rear view mirrors


the parking and standing lamps


the front side marker lamps


the high mounted brake lamps


the brake, tail and rear standing lamps


the rear side marker lamps


the rear fog lamp


the rear turn signal lamps


the rear side marker lamps


the license plate lamps
Replacing bulbs for front lamps
Before you start to replace a bulb for a
front lamp, do the following first:
Turn the exterior lamp switch to M
(page 342).

Open the hood (
page 492) (except
for side marker lamps).
Warning!
G
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:

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.
i
Have the headlamp adjustment checked
regularly.
