Warning!G
To help avoid personal injury during a
collision or sudden maneuver, exercise care
when storing objects in the vehicle. Put
luggage or cargo in the cargo compartment
if possible. Do not pile luggage or cargo
higher than the seat backs.
Always use cargo net* when transporting
cargo. Cargo net* cannot secure hard or
heavy objects.
Parcel nets cannot secure hard or heavy
objects.
Keep compartment lids closed. This will help
to prevent stored objects from being thrown
about and injuring vehicle occupants during

braking

vehicle maneuvers

an accident
iDepending on vehicle equipment, a
CD changer* and an AUX-socket are located in
the glove box.

Switch on the ignition (page 39).
Flip up cover and insert electrical plug
(cigarette lighter type).
!The lighter socket can accommodate 12V
DC electrical accessories (up to a maximum of
85 W) designed for use with the standard “ciga-
rette lighter” plug type. Keep in mind, however,
that connecting accessories to the lighter socket
(for example extensive connecting and discon-
necting, or using plugs that do not fit properly)
can damage the lighter socket. With the socket
damaged, the lighter may no longer be able to be
placed in the heating (pushed-in) position, or the
lighter may pop out too early with the lighter not
hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC elec-
trical accessories designed for use with the stan-
dard “cigarette lighter” plug type to the
12V power outlets (
page 314) in your vehicle
whenever possible.
!The cigarette lighter is not designed for use
with the electric air pump (
page 499). Use a
power outlet (
page 314) for electric air pump
operation.
iIf the engine is off, and the cigarette lighter
is being used extensively, the vehicle battery
may become discharged.
!If you use all power outlets in the vehicle,
make sure that the maximum current drawn
does not exceed 55 A.
iThe power outlets can be used to
accommodate 12V DC electrical accessories
(e.g. air pump, auxiliary lamps) up to a maximum
of 240 W.
If the engine is off and the power outlets are
being used extensively, the vehicle battery may
become discharged.
iYou can use the power outlets, except for
the power outlet in the front center console,
even if the ignition is switched off.
An emergency shut-off feature ensures that the
vehicle’s electrical voltage does not fall below a
minimum level. If the voltage drops to this mini-
mum level, the power outlets are automatically
switched off. This ensures that enough power
remains to start the engine.

Driving instructions
Standing water
To prevent water from entering the pas-
senger compartment or the engine com-
partment if you must drive through
standing water, keep in mind that

the maximum depth of the water may
not exceed 10 in (25 cm)

you must drive slowly
Passenger compartment
iVehicles with AIRMATIC*:
If you have selected the raised level
(
page 279) before driving through standing
water, the maximum water depth is
12 in (30 cm).
!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
passenger 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
ingested by the engine through the air intake,
causing 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 rear cargo compartment is the preferred
place to carry objects. Always use the cargo
net* when transporting cargo. The cargo
net* cannot secure hard or heavy objects.
Always fasten items being carried as
securely as possible using the cargo
tie-down rings in the cargo floor area and
fastening materials.
