Shift the automatic transmission to
neutral positionN.
Release the brake pedal.

(
page 59).
Switch off the ignition and leave the
SmartKey with KEYLESS-GO* in the
starter switch.Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a damp cloth.Headlamps, brake lamps, tail lamps,
side markers, turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham-
poo, with plenty of water.
iAfter running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 431). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.
When leaving the car wash, make sure that the
mirrors are folded out. Otherwise they may
vibrate.
!Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings may
have chrome appearance, they could be made of
anodized aluminum that will be damaged when
cleaned with chrome cleaner. Instead, use a
damp cloth to clean those ornamental moldings.
For very dirty ornamental moldings of which you
are sure are chrome-plated, use a chrome clean-
er. If in doubt whether an ornamental molding is
chrome-plated, contact an authorized
Mercedes-Benz Light Truck Center.
!Only use window cleaning solutions that are
suitable for plastic lamp lenses. Window clean-
ing solutions which are not suitable may damage
the plastic lamp lenses of the headlamps. There-
fore, do not use abrasives, solvents or cleaners
that contain solvents.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry
cloth or sponge.
Otherwise you may scratch or damage the lens
surface.

Front Passenger Airbag
Enabled
See Operator’s ManualFront passenger front air bag
is activated while driving even
though a child, small
individual, or object below the
system’s weight threshold is
on the front passenger seat,
or the front passenger seat is
empty. Objects on the seat or
forces acting on the seat may
make the system sense sup-
plemental weight.Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Apply the parking brake (page 67).
Switch off the ignition (page 42).
Remove child and child restraint from front passenger seat and properly
secure the child in rear seat employing the child restraint if necessary.
Remove any other items from on and around the front passenger seat
and make sure the storage bag on the back of the front passenger seat
is empty.
Make sure that no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged behind or around the
seat, head restraints pushing against roof etc.). The system may recog-
nize such forces as supplemental weight and sense that an occupant on
the front passenger seat is of a greater weight than actually present.
Keep the seat unoccupied, close the front passenger door and switch
on the ignition (
page 42).
