the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.Replacement batteries: Lithium, type
CR 2025 or equivalent.

Replacing bulbs
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, contact an authorized
Mercedes-Benz Light Truck Center.Have the LEDs and bulbs for the following
lamps replaced at an authorized
Mercedes-Benz Light Truck Center:

the additional turn signal lamps in the
exterior rear view mirrors

the Bi-Xenon lamps

the locator lighting lamps in the
exterior rear view mirrors
Warning!G
Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before
changing a bulb.
Keep bulbs out of reach of children.
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.
!Do not replace the LEDs yourself. You could
otherwise damage the LEDs or parts of the vehi-
cle. Only have the LEDs replaced at an autho-

Warning!G
For safety reasons, switch off wipers and
remove SmartKey from starter switch
before replacing a wiper blade. Otherwise,
the wiper motor could suddenly turn on and
cause injury.
Warning!G
Wiper blades are components that are
subject to wear and tear. Replace the wiper
blades twice a year, preferably in the spring

properly wiped. As a result, you may not be
able to observe surrounding traffic condi-
tions and could cause an accident.

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.

shield glass without a wiper blade inserted.
For your convenience, you should have this work
carried out at an authorized Mercedes-Benz
Light Truck Center.!Do not pull on the wiper blade inserts. They
could tear.

spare wheel carrier (
page 368).
Take the vehicle tool kit out of its
storage compartment (
page 366).
Take the vehicle jack out of its storage
compartment (

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizeable
objects.
When changing wheel on a level surface:
Place one wheel chock in front of and
one 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
circumstances require you to do so on a
hill, place the wheel chocks as follows:
Place the wheel chocks on the downhill
side blocking both wheels of the axle
not being worked on.
Warning!G
For your safety, remove spare wheel from
spare wheel carrier before undertaking any
further steps.
Warning!G
The jack is designed exclusively for jacking
up the vehicle under the axle housing. 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,
especially on hills. Always try to use the jack
on level surface.
Make sure the jack is positioned correctly
under the axle housing. Always lower the
vehicle onto sufficient capacity jackstands
before working under the vehicle.
If the vehicle is not raised as described, it
could slip off the jack as a result of vibra-
tions (e.g. opening or closing a door or the
tailgate).
