Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. After an accident, immediately
switch the ignition off and remove the key
from the ignition lock.
If components of the restraint system are
activated during an accident, the hybrid sys-
tem is automatically deactivated.
The hybrid system is not activated when the
vehicle is started if:
R a short circuit is detected in the hybrid sys-
tem.
R a hybrid system electrical connection is
disconnected.
This ensures that you do not come into con-
tact with high voltage.
Manual deactivation of the hybrid sys-
tem The hybrid system can be deactivated man-
ually using the high voltage switch-off device.
! To prevent damage to the hybrid system
please observe the following instructions:
R only deactivate the hybrid system man-
ually in the following situations.
R work on the hybrid system may only be
carried out at a qualified specialist work-
shop, even when it has been deactivated
manually.
R if the 6 restraint system warning lamp
in the instrument cluster lights up after an
accident.
R if the vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated.
R if 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
turning. 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
position P.

until it engages in the stop position.
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. Hybrid vehicles

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 vehi-
cle standing idle for lengthy periods can
damage the high-voltage battery.
If the vehicle is idle for lengthy periods, run
it for a few minutes once every six weeks to
charge up the high-voltage battery.
During the charging process, switch off all
electrical consumers, e.g. the automatic
climate control or the seat heating.
Information on charging the high-voltage bat-
tery (Y page 416).

Introduction to the restraint system
The restraint system reduces 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. 44
Occupant safetySafety

The restraint system includes the:
R seat belt system
R airbags
R child restraint system
R child seat securing system
The components of the restraint system work
in conjunction with each other. They can only
offer protection if all vehicle occupants
always:
R have the seat belt correctly fastened
(Y page 48)
R have the seat and head restraint adjusted
properly (Y page 119)
As the driver, you must also make sure that
the steering wheel is also adjusted properly.
Observe the information on the correct driv-
er's seat position (Y page 118).
In addition, you must make sure that the air-
bags can inflate properly if they are deployed (Y page 51).
An airbag supplements a correctly worn seat
belt and, as an additional safety device,
increases protection for vehicle occupants in
applicable accident situations. The airbags
are not deployed, for example, in the event of an accident in which sufficient protection is
offered by the seat belt. In addition, only
those airbags, which in the applicable acci-
dent situations offer additional protection,
are deployed in the event of an accident.
However, the seat belt and airbag generally
do not protect against objects penetrating
the vehicle from the outside.
Information on how the restraint system
operates can be found under "Deployment of
belt tensioners and airbags" (Y page 60).
See "Children in the vehicle" for further infor- mation on children travelling in the vehicle as
well as on child restraint systems
(Y page 63). 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
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to modify an airbag system to
accommodate a person with disabilities, con- tact an authorised Mercedes-Benz Centre. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at regular intervals while the engine is run-
ning. Therefore, malfunctions can be detec-
ted in good time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the igni- tion is switched on. It goes out no later than afew seconds after the engine is started. The
components of the restraint system are in
operational readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
R does not light up after the ignition is
switched on
R does not go out after a few seconds with
the engine running
R lights up again while the engine is running
All vehicles, except hybrid vehicles: G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensioners or airbags, for example. Occupant safety
