ual The front-passenger air bag is deactivated during the journey, even
though:
R an adult
or
R a person of the corresponding stature is on the front-passenger
seat
If additional forces are applied to the seat, the system may inter-
pret the occupant's weight as lower than it actually is.
G WARNING
The front-passenger air bag does not deploy during an accident.
There is an increased risk of injury. X Pull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions.
X Secure the vehicle against rolling away (Y page 220).
X Switch the ignition off.
X Have the occupant get out of the vehicle.
X Keep the seat unoccupied, close the front-passenger door and
switch on the ignition.
X Observe the PASSENGER AIR BAG indicator lamps in the center
console and the multifunction display and check the following:
Seat unoccupied and ignition switched on:
R the PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON
indicator lamps must light up simultaneously for approx-
imately six seconds.
R the PASSENGER AIR BAG OFF indicator lamp must then light
up and remain lit. If the indicator lamp is on, OCS has disabled the front-passenger air bag (Y page 60).

WARNING
If you do not correctly store objects in the
vehicle interior, they can slip or be flung
around, thus striking vehicle occupants.
There is a risk of injury, especially when brak- ing or abruptly changing directions. R
Always store objects so that they cannot be
flung around in these or in similar situa-
tions.
R Always make sure that objects do not pro-
trude from stowage compartments, parcel

The sockets can be used for accessories with a maximum draw of 180 W (15 A). Accesso-
ries include such items as chargers for mobile
phones.
If you use the sockets for long periods when
the engine is switched off, the battery may
discharge.
An emergency cut-out ensures that the on-
board voltage does not drop too low. If the on-
board voltage is too low, the power to the
sockets is automatically cut. This ensures
that there is sufficient power to start the
engine.

DANGER
When a suitable device is connected, the
115 V power socket will be carrying a high
voltage. You could receive an electric shock if the connector cable or the 115 V power
socket is pulled out of the trim or is damaged
or wet. There is a risk of fatal injury. Features

R
Use only connector cables that are dry and
free of damage.
R When the ignition is off, make sure that the
115 V power socket is dry.
R Have the 115 V power socket checked or

power socket should only be carried out by
qualified specialist personnel.
General notes The 115 V power socket provides an alter-
nating voltage of 115 V so that small elec-
tronic devices can be connected. These devi- ces, such as games consoles, chargers and
laptops, must not consume more than a max-imum of 150 watts altogether.
Requirements for operation of these devices:
R the electronic device that you connect has
a suitable connector and conforms to
standards specific to the country you are in.
R the plug of the electronic device is plugged
correctly into 115 V power socket.
R the maximum wattage of the device to be
connected must not exceed 150 watts.
R the on-board power supply is within a per-
missible voltage range.
