Replacing bulbsSafe 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.

low the lamp to cool down before changing
a 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

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.

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 55).
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 56).
Open the driver’s door (this puts the

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 and Sport Package* only:
The spare wheel is for temporary use only.
When driving with spare wheel mounted, en-
sure proper tire pressure and do not exceed
vehicle speed of 50 mph (80 km/h).
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.
