Operation
Vehicle care
Engine cleaning
Prior to cleaning the engine compartment
make sure to protect electrical compo-
nents and connectors from the intrusion of
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax, should be applied to the en-
gine compartment after every engine
cleaning. Before applying, all control link-
age bushings and joints should be lubricat-
ed. The poly-V-belt and all pulleys should
be protected from any wax.
Vehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Use only a mild car wash
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water. Direct only a very weak
spray towards the ventilation intake. Use
plenty of water and rinse the sponge and
chamois frequently.
Rinse with clear water and thoroughly dry
with a chamois. Do not allow cleaning
agents to dry on the finish.
Due to the width of the vehicle, fold in ex-
terior rear view mirrors prior to running the
vehicle through an automatic car wash to
prevent damage to the mirrors.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the underbody, do not
forget to clean the inner sides of the
wheels. Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, side markers,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not
attempt to wipe dirty lenses with a dry
cloth or sponge.

Front-pass
airbag deactivated
See Operator’s Manual
Air bag is deactivated while driv-
ing even though an adult or some-
one larger than a small individual
is occupying the front passenger
seat. Forces acting on the seat
may make the system sense a
decrease in weight.
Stop the vehicle in a safe location as soon as possi-
ble and check the following:
Do not lean on armrests or lift yourself up using
handle over the door. This may make the system
sense that an occupant of a lesser weight than
actually present is on the front passenger seat.

Re-position yourself.

Sit properly belted in a nearly upright position
with your back against the seat backrest.
If performing any of the above corrective steps is
successful, the message
Front-pass airbag
activated See Operator’s Manual
will appear in the
multifunction display, confirming the situation has
been remedied.
