Deactivate the hybrid system manually if:
R the 6 restraint system warning lamp in the
instrument cluster lights up after an accident
R the vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated
R the vehicle is badly damaged and has to be
towed or transported
X If possible, move the vehicle out of the
danger zone:
shift the automatic transmis-
sion into position N.
X Release the electric parking brake.
X Roll the vehicle to a safe place and park it
safely.
Get assistance from others if necessary.
The vehicle is locked automatically when the
ignition is switched on and the wheels are turn-
ing. There is therefore a risk of being locked out
if the vehicle is being pushed or tested on a
dynamometer.
X Switch the ignition off.
X Shift the automatic transmission to park posi-
tion P.
Apply the electric parking brake
(Y page 192).
Secure the vehicle against rolling away
(Y page 414).
X To use the high-voltage switch-off device:
open the tailgate.
X Lift the luggage compartment floor upwards
(Y page 359).
X Pull off the right-hand trim in the luggage
compartment. X
Press release clip :in the direction of the
arrow and pull it out.
X Pull high voltage switch-off device ;apart
until it engages in the stop position. If the hybrid drive system has been deactivated
due to reasons mentioned above, have it
checked at a qualified specialist workshop
before reactivation.
High-voltage battery G
WARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery could exceeda critical value. In this case, flammable gas
escapes through a vent valve in the vehicle's
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger area immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements. G
WARNING
If the housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. These are poisonous and caustic.
There is a risk of injury.
Avoid contact with the skin, eyes or clothing. Immediately rinse electrolyte splashes off
with water and seek medical attention
straight away.
! Exhaustive discharge caused by the vehicle
standing idle for lengthy periods can damage
the high-voltage battery. If the vehicle is idle
for lengthy periods leave the high-voltage bat- tery connected to a charging station.
Charging the high-voltage battery (Y page 182).

X Apply the electric parking brake.
X Shift the transmission to position P.
X Switch the ignition off.
X Remove the key from the ignition lock.

X Remove the Start/Stop button from the igni-
tion lock. 42

Introduction to the restraint system
The restraint system can reduce the risk of vehi- cle occupants coming into contact with parts of the vehicle's interior in the event of an accident.
The restraint system can also reduce the forces to which vehicle occupants are subjected during
an accident.
The restraint system comprises:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing systems
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if all vehicle
occupants always:
R fasten their seat belts correctly
(Y page 46)
R adjust their seat and head restraint properly
(Y page 108).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (Y page 107).
You also have to make sure that an airbag can
inflate properly if deployed (Y page 48).
An airbag supplements a correctly fastened seat belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if the protection of the seat belt is sufficient in an accident, the airbags are not deployed. In
the event of an accident, only the airbags that
increase protection in the relevant accident sit- uation are deployed. However, seat belts and
airbags generally do not protect against objects penetrating the vehicle from the outside.
Information on the restraint system operation
can be found under "Triggering of belt tension-
ers and airbags" (Y page 55).
For more information about children travelling
with you in the vehicle, see "Children in the vehi-
cle" (Y page 58). Important safety notes

WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering Occupant safety

The indicator lamps inform you whether the
front-passenger front airbag is disabled or ena-
bled.
X Press the Start/Stop button once or twice, or
turn the key to position 1or 2in the ignition
lock.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul- taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front airbag:
R PASSENGER AIR BAG ON lights up: the front-
passenger front airbag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front airbag is
deployed.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the status of the front-passenger front airbag
changes while the vehicle is in motion, an airbag display message appears in the instrument clus-
ter (Y page 311). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status of the front-passenger front airbag both before
and during the journey.
If a person sits in the passenger seat, they must
be:
R seated with the seat belt fastened correctly
R in an almost upright position with their back
against the seat backrest
R with their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, the automatic front-passenger front
airbag deactivation system may be influenced,
e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
The front-passenger front airbag may be disa-
bled by mistake as a result of these or similar
actions. In this case, the PASSENGER AIR BAG
OFF indicator lamp lights up permanently. The
front-passenger front airbag does not then
deploy during an accident. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always make sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger front airbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front airbag is correct. G
WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The child could be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG
ON indicator lamp lights up, do not install a rear- ward-facing child restraint system on the front-
passenger seat. Further information can be
found under "Problems with the automatic front-
passenger front airbag deactivation system"
(Y page 55). 52
