Replacing bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp
assemblies 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
adjustment.!Do not replace the LEDs or bulbs yourself.
You could otherwise damage the vehicle lighting
system or parts of the vehicle. Only have the
LEDs or bulbs replaced by an authorized
Mercedes-Benz Center.
iIf the headlamps are fogged up on the inside
as a result of high humidity, driving the vehicle a
distance should clear up the fogging.
iSubstitute bulbs will be brought into use
when lamps malfunction. Observe the messages
in the multifunction display (
page 341).
iIf one of the following bulbs blows, another

Flat tire
The vehicle is equipped with the TIREFIT
kit.
Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.
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 to park
positionP.
Turn off the engine (page 56).
Remove the SmartKey from the starter
switch.
Have any passenger exit the vehicle at
a safe distance from the roadway.
Sealing tires with TIREFIT
Small tire punctures, particularly those in
the tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient tempera-
tures down to -4°F (-20°C).
Foreign objects (e.g. screws or nails)
should not be removed from the tire.
Take TIREFIT, the sticker, and the
electric air pump out of the trunk.
Attach the sticker where it will be easily
seen by the driver on the instrument
cluster.
!A wheel change should only be carried out
at an authorized Mercedes-Benz Center. Other-
wise there is a danger of damaging the vehicle by
jacking it up incorrectly.
iOpen door only when conditions are safe to
do so.
Warning!G
Keep TIREFIT away from sparks, open flame
or heat source.
Do not smoke.
Warning!G
TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approximately 0.16 in (4 mm) and tire
damage caused by driving with extremely
low tire inflation pressure, or on a flat tire, or
a damaged wheel.
Do not drive the vehicle under such
circumstances.
Contact your nearest Mercedes-Benz
Center for assistance or call Roadside
Assistance.
!After using TIREFIT, the tire inflation
pressure sensor may have to be replaced.

Batteries
Charging the batteries
You can obtain detailed information on
charging the battery from your authorized
Mercedes-Benz Center.
Warning!G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. The same applies if
battery is disconnected. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is
increased! Adjust your driving style
accordingly. For more information, see
“Electro-hydraulic brake system”
(
page 86).
Warning!G
With a disconnected battery

you will no longer be able to turn the
SmartKey in the starter switch

the gear selector lever will remain
locked in park positionP
Warning!G
Never charge a battery while still installed in
the vehicle unless the battery charge unit
approved by Mercedes-Benz (supplied with
your vehicle) is being used. Gases may es-
cape during charging and cause explosions
that may result in paint damage, corrosion
or personal injury.
A battery charge unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available,
permitting the charging of the battery in its
installed position. Contact an authorized
Mercedes-Benz Center for information and
availability. Charge battery in accordance
with the separate operating instructions for
the battery charger.
