Roof rack
Use only those roof racks approved by Mercedes-Benz.
Follow manufacturer’s installation instructions. They
mount to the roof rails and do not require additional
supports (e.g. suction cups or legs). Such supports may
lead to marring of the paint or denting the roof. For
further information inquire at your Mercedes-Benz
Light Truck Center.
Take into consideration that when the roof rack is
loaded, the handling characteristics are different from
those when operating the vehicles without the roof rack
loaded.

Cleaning and care of the vehicle
In operation, your vehicle is subjected to varying
external inf luences which, if gone unchecked, can
attack the paintwork as well as the underbody and
cause lasting damage.
Such damage is caused not only by extreme and varying
climatic conditions, but also by air polution, road salt,
tar, gravel and stone chipping. Grease and oil, fuel,
coolant, brake fluid, bird droppings, insects, tree resins
etc. should be removed immediately to avoid paint
damage. Frequent washing reduces and / or eliminates
the aggressiveness and potency of the above adverse
influences. More frequent washings are necessary to deal with
unfavorable conditions; for example, near the ocean, in
industrial areas (smoke, exhaust emissions), or during
winter operation.
You should check your vehicle from time to time for
stone chipping or other damage. Any damage should be
repaired as soon as possible to prevent the start of
corrosion.
In doing so, do not neglect the underside of the vehicle.
A prerequisite for a thorough check is a washing of the
underbody followed by a thorough inspection. Damaged
areas need to be reundercoated.
Your vehicle has been treated at the factory with a wax-
base ru stproof ing in th e body cavities w hich will la st for
the lifetime of the vehicle. Post-production treatment is
neither necessary nor recommended by Mercedes-Benz
because of the possibility of incompatibility between
materials used in the production process and others
applied later.
We have selected car-care products and compiled
recommendations which are specially matched to our
vehicles and which always reflect the latest technology.
You can obtain Mercedes-Benz approved car-care
products at your authorized Mercedes-Benz Light Truck
Center.
Wa r n i n g !
Many cleaning products can be hazardous. Some
are poisonous, others are flammable. Always follow
the instructions on the particular container.
Always open your vehicle’s doors or windows when
cleaning the inside.Never use fluids or solvents that are not designed
for cleaning your vehicle.

SERVICING
SRS AIR BAG label on driver-side door latch post indicates SRS replacement date for air bag units. All SRS
components must be thoroughly inspected, including wiring harness. Before component replacement, check for
SRS fault codes by performing system operation check. See SYSTEM OPERATION CHECK
. SRS service
life is 10 years from manufactured date or 10 years from SRS replacement date after accident related repairs are
completed.
SYSTEM OPERATION CHECK
SRS warning light indicates SRS and Emergency Tensioning Retractor (ETR) system readiness. Turn ignition
on. SRS warning light will illuminate, then turn off after approximately 4-6 seconds indicating SRS system is
functioning properly. If SRS warning light does not illuminate, illuminates while driving or is continuously
illuminated, there is a system fault. Repair malfunctioning system.
AIR BAG SAFETY PRECAUTIONS
Observe these precautions when servicing the air bag system:
When working around SRS components and before any repairs are performed, disable air bag system. See
DISABLING & ACTIVATING AIR BAG SYSTEM
.
Before straightening any damage to body, or before performing electrical arc-welding, disable air bag
system. See DISABLING & ACTIVATING AIR BAG SYSTEM
.
Always wear safety glasses and gloves when handling a deployed air bag module. Air bag module may
contain sodium hydroxide deposits which are irritating to the skin.
Always use control module and impact sensors made by same manufacturer. Using components produced
by different manufacturers could cause accidental air bag or ETR deployment.
DO NOT repair any portion of SRS wiring harness.
If any SRS component is dropped from a height greater than 1.6 feet (0.5 m), it must be replaced.
If SRS components show signs of damage, they must be replaced.
Always handle air bag module with trim cover facing away from your body.
Always place air bag module on workbench with trim cover up, away from loose objects.
