sion or sudden maneuver, exercise care
when storing objects in the vehicle. Put lug-
gage or cargo in the trunk if possible. Do not
pile luggage or cargo higher than the seat
backs. Do not place anything on the shelf
below the rear window.

Driving abroad
Abroad, there is an extensive
Mercedes-Benz service network at your
disposal. If you plan to drive into areas
which are not listed in the index of your
Mercedes-Benz Center directory, you
should request pertinent information from
an authorized Mercedes-Benz Center.Control and operation of radio
transmitters

!Do not drive through flooded areas or water
of unknown depth. Before driving through water,
determine its depth. Never accelerate before
driving into water. The bow wave could force wa-
ter into the engine and auxiliary equipment, thus
damaging them.
If you must drive through standing water, drive
slowly to prevent water from entering the pas-
senger compartment or the engine compart-
ment. Water in these areas could cause damage
to electrical components or wiring of the engine
or transmission, or could result in water being in-
gested by the engine through the air intake caus-
ing severe internal engine damage. Any such
damage is not covered by the Mercedes-Benz
Limited Warranty.
Warning!G
Always fasten items being carried as
securely as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The trunk is the preferred place to carry
objects.
Warning!G
Please do not forget that your primary
responsibility is to drive the vehicle safely.
Only operate the COMAND (Cockpit
Management and Data System), radio or
telephone
1 if road, weather and traffic
conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
1Observe all legal requirements.

Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the headlamps, then it is not

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 supple-
mental weight.Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Switch off the ignition (page 32).
Remove child and child restraint from front passenger seat and proper-
ly secure the child in rear seat employing the child restraint if neces-
sary.
Make sure that no objects applying supplemental weight onto the seat
are present. The system may recognize such 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 (
