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.

Bulbs and bulb sockets can get 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.

dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.

Replacing wiper blades
Replacing wiper blades
Wiper blades in vertical position
Removing wiper blades
Turn SmartKey in starter switch to
position1.
Turn combination switch to wiper
settingII (
page 54).
With wiper arm in vertical position, turn
SmartKey in starter switch to
position0.
Fold the wiper arm forward until it
snaps into place.
Turn the wiper blade at a right angle to
wiper arm (arrow 1).
Slide the wiper blade sideways out of
the retainer in the direction of
arrow2.
!To avoid damage to the hood, the wiper
arms should only be folded forward
when in the vertical position.
Warning!
G
For safety reasons, switch off wipers and re-
move SmartKey from starter switch (vehi-
cles with KEYLESS-GO*: Make sure the
vehicle's on-board electronics have status
0) before replacing a wiper blade. Other-
wise, the wiper motor could suddenly turn
on and cause injury.

380 Practical hintsReplacing wiper bladesInstalling wiper blades
Slide the wiper blade onto wiper arm
until it locks in place.
Rotate the wiper blade into position
parallel to wiper arm.
Fold the wiper arm backward to rest on
the windshield. Make sure you hold
onto 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.

Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.
Turn on the hazard warning flashers.
Turn the steering wheel so that the
front wheels are in a straight ahead
position.
Set the parking brake.
Move the gear selector lever toP.
Vehicles with SmartKey:
Turn off the engine (
page 59).
Remove the SmartKey from the starter
switch.Vehicles with SmartKey with
KEYLESS-GO*:
Turn off the engine by pressing the
KEYLESS-GO* button on the gear se-
lector lever once (
page 59).
Open the driver’s door (this puts the
starter switch 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.
Mounting the spare wheel
iOpen door only when conditions are
safe to do so.
Warning!
G
Never operate the vehicle with more than
one spare wheel mounted.
The spare wheel rim is for temporary use
only. Use for over a total of 12 000 miles
(20 000 km) (aggregate of all uses) may
cause wheel rim failure leading to an acci-
dent and possible injuries.
The spare wheel should only be used tempo-
rarily and replaced with a regular road wheel
as quickly as possible.
CL 55 AMG, CL 65 AMG and Sport Pack-
age* only:
The spare wheel is for temporary use only.
When driving with spare wheel mounted, en-
sure proper tire inflation pressure and do
not exceed vehicle speed of 50 mph
(80 km/h).

382 Practical hintsFlat tirePreparing the vehicle
Take vehicle tool kit tray and vehicle
jack out of trunk.
Take the spare wheel out of wheel well
(page 366).
Lifting the vehicle
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:
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:
Place chocks behind the downhill sides
of both wheels of the axle not being
worked on.
Take the two-piece wheel wrench out
of the vehicle tool kit tray. Assemble
wheel wrench.
On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench).
The tube openings are located directly be-
hind the front wheel housings and in front
of the rear wheel housings.
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a mounted spare
wheel. Adapt your driving style accordingly.
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 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.
