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).
Engine compartment Before opening the bonnet:
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.
or, on vehicles with KEYLESS-GO start function
or KEYLESS ‑GO:
X Remove the Start/Stop button from the igni-
tion lock. 42

tive Brake System)
The Recuperative Braking System supports you
when braking with an electronically-controlled
brake boost mode and enables the recovery of
kinetic energy (recuperation).

X Press the Start/Stop button.
The key must be in the vehicle.
The panic alarm function is only available in cer- tain countries. 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.
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
