6Bulb holder of low beam bulb
Before you start to replace a bulb for a
front lamp, do the following first:

Turn the exterior lamp switch to
positionM (
page 134).

Open the hood (
page 293) (except
for side marker lamps).Low beam bulb (halogen headlamps
only)

Turn housing cover1 counterclock-
wise and remove it.

Turn bulb holder6 with the bulb coun-
terclockwise and remove it.

Pull the bulb at its socket out of bulb
holder6.

Insert the new bulb so that its socket
locates in the recess of bulb holder6
and is level to it.

Reinsert bulb holder6 with the bulb in
the lamp and turn clockwise.

Align housing cover1 and turn it
clockwise.
Warning!
G
Do not remove the cover1 for the Bi-Xe-
non* headlamp. 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.

418 Practical hintsReplacing wiper bladesInstalling wiper blades
Slide wiper blade onto wiper arm until
it locks in place.

Rotate wiper blade into position paral-
lel to wiper arm.

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.

424 Practical hintsFlat tirePreparing the vehicle
Prepare the vehicle as described under
“Preparing the vehicle” on this page.
Take the spare wheel out of the trunk
(page 398).

Take the wheel wrench and the jack
out of the trunk (
page 398).
Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizeable objects.
When changing wheel on a level surface:

Place the wheel chock in front of and
another sizeable object behind the
wheel that is diagonally opposite to the
wheel being changed.Always try lifting the vehicle using the jack
on a level surface. However, should cir-
cumstances require you to do so on a hill,
place the wheel chock and the other size-
able object as follows:

Place the wheel chock and another
sizeable object on the downhill side
blocking both wheels of the axle not
being worked on.
1Wheel wrench

On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with
wrench1).
Warning!
G
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
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Be sure that the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.

Lowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.

Remove the jack.
1-5 Wheel bolts

Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 96 lb-ft
(130 Nm).

Before storing the jack in the trunk, it
should be fully collapsed.
MOExtended system*
The MOExtended system allows you to
continue driving your vehicle even if there
is a total loss of pressure in one or more
tires.
You may only use the MOExtended system
in conjunction with the Run Flat Indicator*
or the Advanced TPMS* (Canada only)
(page 314).
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).iWrap the damaged wheel in the protec-
tive film that comes with the spare
wheel and put the wheel in the trunk.
You can also place the damaged wheel
down into the spare wheel well. In this
case, you must stow the luggage bowl
in the trunk.
!The maximum distance in emergency
mode depends on the vehicle’s load. It
is 30 miles (50 km) if the vehicle is par-
tially loaded and 18 miles (30 km) if the
vehicle is fully loaded.
The point at which the maximum driv-
ing distance begins in emergency
mode is when the warning message
appears in the multifunction display
indicating that there is a loss of tire
inflation pressure.
Do not exceed the maximum speed of
50 mph (80 km/h).
