Operation
Engine compartment
ClosingLower hood and let it drop into lock
from a height of approximately 0.7 ft
(20 cm).
The hood will lock audibly.
Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the turn signals to the left and
right of the hood, then it is not properly
closed. Open it again and let it drop
with somewhat greater force.
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher
oil consumption can
occur when

the vehicle is new

the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
Warning!G
When closing the hood, use extreme caution
not to catch hands or fi ngers. Be careful that
you do not close the hood on anyone.
Make sure that the hood is securely
engaged before driving off. Do not continue
driving if the hood can no longer engage
after an accident, for example. The hood
could otherwise come loose while the
vehicle is in motion and endanger you and
others.
!Do not push the hood closed manually, as
this could damage it. !Do not use any special lubricant additives,
as these may damage the drive assemblies.
Using special additives not approved by
Mercedes-Benz may cause damage not covered
by the Mercedes-Benz Limited Warranty.
More information on this subject is available at
any Mercedes-Benz Light Truck Center.

314 Operation
Vehicle care
Cleaning and care of the vehicle
Regular and proper care will help to main-
tain the value of your vehicle. The best way
to protect your vehicle from harmful envi-
ronmental influences is to wash it and use
protective treatments regularly.While in operation, even while parked, your
vehicle is subjected to varying external
influences which, if gone unchecked, can
attack the paintwork as well as the under-
body and cause lasting damage.
Such damage is caused not only by
extreme and varying climatic conditions,
but also by:

Air pollution

Road salt

Tar

Gravel and stone chippingTo avoid paint damage, you should imme-
diately remove:

Grease and oil

Fuel

Coolant

Brake fluid

Bird droppings

Insects

Tree resins, etc.
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:

near the ocean

in industrial areas (smoke, exhaust
emissions)

during winter operation
Warning!G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or windows when cleaning the inside.
Never use fluids or so lvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and
keep them out of reach of children.
