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 high mounted brake lamp

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-
rized Mercedes-Benz Light Truck Center.

if:

it is not more than 6 years old

rim and tire are the same model as the
regular wheels
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 flasher
(
page 124).
Turn the steering wheel so that the
front wheels are in a straight-ahead
position.
Set the parking brake (page 62).
Move the gear selector lever to park
positionP (
page 162).
Turn off the engine (page 64).
Remove the SmartKey from the starter

at the nearest Mercedes-Benz Light Truck
Center.
Never operate the vehicle with more than
one spare wheel mounted.
Warning!G
G55AMG:
Vehicles with different tire dimensions on
the front and rear axle: rim and tire size of
spare wheel and regular wheel differ.
Handling will be adversely affected when the
spare wheel is used.
Do not exceed the maximum speed of
50 mph (80 km/h).
iOpen door only when conditions are safe to
do so.

405 Practical hints
Fuses
Fuses
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and
systems secured by that fuse will stop
operating.If a newly inserted fuse blows again, have
the cause determined and rectified at an
authorized Mercedes-Benz Light Truck
Center.
The following aids are available to help you
replace fuses.

Fuse chart
The fuse chart explains the fuse
allocation and fuse amperages.
The fuse chart is located in the main
fuse box in the passenger compart-
ment (
page 406).

Spare fuses
The spare fuses are located in the main
fuse box in the passenger compart-
ment (
page 406).

Fuse extractor
The fuse extractor is located in the
vehicle tool kit in the rear footwell
(
page 366).The electrical fuses are located in different
fuse boxes:

in the passenger compartment on the
driver’s side (
page 406)

in the front passenger footwell
(
page 406)

in the middle tunnel (page 407)

in the battery box (page 408)
Before replacing fuses:
Apply parking brake (page 62).
Make sure the gear selector lever is set
to park positionP (
page 162).
Turn off all electrical consumers.
Turn off the engine (page 64).
Remove the SmartKey from the starter
switch.
Warning!G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a
fire, and/or cause damage to electrical
components and/or systems. Have the
cause determined and remedied at an
authorized Mercedes-Benz Light Truck
Center.
iA blown fuse must be replaced by an
appropriate spare fuse (recognizable by its color
or the fuse rating given on the fuse) of the
amperage recommended in the fuse chart. Any
Mercedes-Light Truck Center will be glad to
advise you on this subject.

425 Technical data
Fuels, coolants, lubricants, etc.
Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters
required for vehicles with Maintenance
System (U.S. vehicles) or FSS (Canada
vehicles). For a listing of approved engine
oils and oil filters, refer to the Factory
Approved Service Products pamphlet
(USA only), or contact an authorized
Mercedes-Benz Light Truck Center.
Engine oil additives
Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
ing system.
Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Any
authorized Mercedes-Benz Light Truck
Center will provide you with additional
information.
!Using engine oils and oil filters of specifi-
cation other than those expressly required for
the Maintenance System (U.S. vehicles) or FSS
(Canada vehicles), or changing of oil and oil filter
at change intervals longer than those called for
by the Maintenance System (U.S. vehicles) or
FSS (Canada vehicles) will result in engine
damage not covered by the Mercedes-Benz
Limited Warranty.Please follow Maintenance System
(U.S. vehicles) or FSS (Canada vehicles)
recommendations for scheduled oil changes.
Failure to do so will result in engine damage not
covered by the Mercedes-Benz Limited
Warranty.
!Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from blending
oil additives are not covered by the
Mercedes-Benz Limited Warranty.
!Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the system
will occur.
Warning!G
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere. Under extremely strenuous
operating conditions, this moisture content
can lead to the formation of bubbles in the
system, thus reducing the system’s
efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.
