Replacing bulbs
Rear lamps 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.

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.iHave the headlamp adjustment
checked regularly.

Replacing wiper blades
Replacing wiper blades
Removing wiper blades
Remove SmartKey from starter switch
(vehicles with KEYLESS-GO*: make
sure the vehicle's on board electronics
have status 0).

Fold the wiper arm forward.1Unlock
2Lock

Pull the tab in direction of arrow1 and
remove windshield wiper.
Installing wiper blades
Slide the wiper blade into the cutout on
the wiper arm (see arrows).

Slide the tab back in the direction of
arrow2 until it audibly engages.

Fold the wiper arm backward to rest on
the windshield. Make sure you hold on
to the wiper when folding the wiper arm
back.
Warning!
G
For safety reasons, switch off wipers and
remove SmartKey from starter switch
(vehicles with KEYLESS-GO*: make sure the
vehicle's on-board electronics have
status
0) before replacing a wiper blade.
Otherwise, the wiper motor could suddenly
turn on and cause injury.
!Never open the hood when the wiper
arms are 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.

422 Practical hintsFlat tire
Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.

Turn on the hazard warning flashers
(page 127).

Turn the steering wheel so that the
front wheels are in a straight ahead
position.

Set the parking brake (
page 55).

Move the gear selector lever toP.
Vehicles with SmartKey:

Turn off the engine (
page 56).

Remove the SmartKey from the starter
switch.Vehicles with SmartKey with
KEYLESS-GO*:

Turn off the engine by pressing the
KEYLESS-GO* start/stop button on the
gear selector lever once (
page 57).

Open the driver’s door (this puts the ig-
nition in position0, same as with the
SmartKey removed from the starter
switch). The driver’s door then can be
closed again.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Warning!
G
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. Adapt your driving style
accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed a vehicle speed of 50 mph
(80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
iOpen door only when conditions are
safe to do so.

Mounting the Minispare wheel
Preparing the vehicle
Prepare the vehicle as described on
(page 422).

Take the wheel wrench and the jack
out of the trunk (
page 394).

Take the Minispare wheel and wheel
bolts out of the trunk (
page 394).
Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizable objects.
One wheel chock is included with the
vehicle tool kit (
page 391).
When changing wheel on a level surface:

Place the wheel chock in front of and
another sizable object behind the
wheel that is diagonally opposite to the
wheel being changed.
When changing wheel on a hill:

Place the wheel chock and another
sizable object on the downhill side
blocking both wheels of the other axle.
1Wheel wrench

On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench).
The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.
Warning!
G
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, es-
pecially on hills. Always try to use the jack
on a level surface. Make sure 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.

424 Practical hintsFlat tire2Jack
3Take-up bracket
Place jack 2 on firm ground.

Position jack2 under take-up
bracket3 so that it is always vertical
(plumb-line) as seen from the side,
even if the vehicle is parked on an
incline.

Jack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the
ground. Never start engine while
vehicle is raised.Removing the wheel
1Alignment bolt

Unscrew upper-most wheel bolt and
remove.

Replace this wheel bolt with alignment
bolt1 supplied in the tool kit.

Remove the remaining bolts.

Remove the wheel.
Warning!
G
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 start the engine when the vehicle
is raised.


Never lie down under the raised vehicle.
!Do not place wheel bolts in sand or dirt.
This could result in damage to the bolt
and wheel hub threads.

425 Practical hints
Flat tire
Mounting the new wheel
1Wheel bolt for light alloy rims
2Wheel bolt for Minispare wheel or other
steel rims (located in trunk with spare
wheel)
Clean contact surfaces of wheel and
wheel hub.

Guide the spare wheel onto the align-
ment bolt and push it on.

Insert wheel bolts and tighten them
slightly.
!Wheel bolts2 must be used when
mounting the Minispare wheel. The use
of any wheel bolts other than wheel
bolts 2 for the Minispare will physical-
ly damage the vehicle's brakes.
!To avoid paint damage, place wheel flat
against hub and hold it there while in-
stalling first wheel bolt.Warning!
G
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.
Make sure to use the correct wheel bolts.

426 Practical hintsFlat tire
Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.Lowering the vehicle

Lower vehicle by turning crank coun-
terclockwise until the full weight of the
vehicle is resting on the ground.

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 80 lb-ft
(110 Nm).Before storing the jack, it should be fully
collapsed, with handle folded in (storage
position) (
page 393).

Store the jack and the other vehicle
tools in the trunk.
Warning!
G
Only use genuine equipment
Mercedes-Benz wheel bolts. Other wheel
bolts may come loose.
Do not tighten the wheel bolts when the ve-
hicle is raised. Otherwise the vehicle could
fall off the jack.
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
80 lb-ft (110 Nm).
