High-voltage battery
GWARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements.
GWARNING
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 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.

Occupant safety
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.
Furthermore, the restraint system may also reduce the forces exerted on the vehicle occu-
pants when an accident occurs.
The restraint system includes:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing system
The components of the restraint system work in
conjunction with each other. They can only offer
the intended level of protection if all vehicle
occupants:
Rare correctly wearing their seat belts.
(Ypage 47)
Radjust their seat and head restraint properly
(Ypage 101).
The driver is also responsible for ensuring that
the steering wheel has been correctly posi-
tioned. Observe the information relating to the
correct driver's seat position (
Ypage 100).
Always ensure the air bag can inflate properly if
deployed (
Ypage 49).
An air bag supplements a correctly fastened
seat belt. As an additional safety device, the air
bag increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if the protection already provided by a cor-
rectly fastened seat belt will suffice, the air bags
are not deployed. Furthermore, only the air bags that would increase the degree of protection
afforded to the vehicle occupants in the event of
an accident are deployed. Seat belts and air
bags generally do not protect against objects
penetrating the vehicle from the outside.
Information on restraint system operation can
be found under "Triggering of Emergency Ten-
sioning Devices and air bags" (
Ypage 56).
See “Children in the vehicle” for information on
children traveling with you as well as vehicle
restraint systems (
Ypage 60).
Important safety notes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.

Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger seat.
Depending on that result, the front-passenger
front air bag is either enabled or deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
In the following situation, the side impact air bag
and the Emergency Tensioning Device are deac- tivated:
ROCS has not categorized the person on the
front-passenger seat as an adult or a person
of corresponding stature and
Rthe seat belt tongue of the seat belt is not
inserted into the front-passenger seat belt
buckle
Prerequisites
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their back
against the seat backrest
Rwith their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce a false classifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selves on a vehicle armrest
Rsits in such a way that their weight is raised
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat, be
sure to observe the correct positioning of the
child restraint system. Never place objects
under or behind the child restraint system, e.g.
cushions. The entire base of the child restraint
system must always rest on the seat cushion of
the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as
flat as possible against the backrest of the front-
passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's installation instructions.
Occupant Classification System opera-
tion (OCS)
:PASSENGER AIR BAG ON indicator lamp
;PASSENGER AIR BAG OFF indicator lamp
The indicator lamps indicate whether the front-
passenger front air bag is activated or deactiva-
ted.
XPress the start/stop button once or twice, or
turn the SmartKey to position 1or 2in the
ignition lock.
The system carries out a self-diagnosis test.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul-
taneously for about six seconds.
The indicator lamps then display the status of
the front-passenger front air bag:
RPASSENGER AIRBAG ON lights up: the front-
passenger front airbag is enabled. If, in the
case of an accident, all deployment criteria
are met, the front-passenger front air bag is
deployed.
RPASSENGER AIRBAG 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 air bag
changes whilst the vehicle is in motion, an air
bag display message may appear in the instru-
ment cluster (
Ypage 290). Always observe the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps when the front-
passenger seat is occupied. Make sure that the
status of the front-passenger front air bag is
correct before and during a journey.
