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.

device: open the bonnet. 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.
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
43Safety Z

The restraint system includes:
R seat belt system
R airbags
R child restraint system
R child seat securing systems
The components of the restraint system are
complementary. They can offer maximum
protection only when all vehicle occupants:
R secure their seat belts correctly
(Y page 48)
R adjust the seat and head restraints prop-
erly (Y page 119)
As the driver, you must also make sure that
the steering wheel is adjusted correctly.
Observe the information on the correct driv-
er's seat position (Y page 118).
Additionally, you must make sure that the air- bag can inflate without restriction if deployed
(Y page 51).
An airbag is supplementary to a correctly fas-
tened seatbelt. An airbag, as an additional
safety device, provides greater protection for vehicle occupants in an accident situation. If
the seat belts offer sufficient protection in the
event of an accident, for example, the airbags
will not be deployed. Also, only the airbags
which are deemed to offer protection in the
corresponding accident situation are
deployed. However, seat belts and airbags
generally do not protect against objects pen-
etrating the vehicle from the outside.
Information on how the restraint system
operates can be found in "Deployment of the seat belt tensioner and airbags"
(Y page 60).
See "Children in the vehicle" (Y page 63) for
further information on infants and children
travelling in the vehicle as well as on child
restraint systems. Important safety notes
G
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
for a person with physical disabilities, contact a Mercedes-Benz Service Centre for details. 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 vehicle 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

Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. This
function adjusts the driver's and front-
passenger seat belt to the upper body of the
occupants.
The belt strap is tightened slightly when:
R the seat belt tongue is engaged in the belt
buckle and
R the ignition is switched on
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off using COMAND Online or Audio 20.
Information on switching the seat-belt adjust-
ment function on and off can be found in the
Digital Owner's Manual or in the separate COMAND Online or Audio 20 operating
instructions.
Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle
occupants must wear their seat belts. It may
light up continuously or flash. In addition, a
warning tone may sound.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the front passenger have fastened their seat
belts.
i For more information on the
7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belt" (Y page 353).
Rear seat belt status indicator The rear seat belt status indicator is only
available for certain countries.
For approximately 30 second s,the rear seat
belt status indicator informs you which rear
seat belt is not fastened.
The rear seat belt status indicator appears if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
you pull away again. 50
Occupant safetySafety

If children are travelling in the vehicle, be sure
to observe the notes on "Children in the Vehi- cle" (Y page 63).
If the automatic front-passenger front airbag
deactivation system is malfunctioning, the
red 6 restraint system warning lamp in
the instrument cluster and the PASSENGER
AIR BAG OFF indicator lamp light up simulta-
neously. The front-passenger front airbag is
disabled in this case and does not deploy dur- ing an accident. Have the system checked as
soon as possible by qualified technicians.
Consult a Mercedes-Benz Service Centre. The
front-passenger seat should only be repaired at a Mercedes-Benz Service Centre.
If the front-passenger seat, the seat cover orthe seat cushion is damaged, have the nec-
essary repair work carried out at a Mercedes- Benz Service Centre.
For safety reasons, Mercedes-Benz recom-
mends that you only use a child restraint sys-
tem which has been tested and approved by
Mercedes-Benz in combination with the auto- matic front-passenger front airbag deactiva-
tion system.
System self-test G
DANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not light up during the system self-test, the
system is malfunctioning. The front-
passenger front airbag might be triggered
unintentionally or might not be triggered at all in the event of an accident with high deceler-
ation. This poses an increased risk of injury or even fatal injury.
In this case the front-passenger seat may notbe used. Do not install a child restraint system
on the front-passenger seat. Have the auto-
matic front-passenger front airbag deactiva-
tion system checked and repaired immedi-
ately at a qualified specialist workshop. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp remains lit after the system self-test, the
front-passenger front airbag is disabled. It willnot be deployed in the event of an accident. In
this case, the front-passenger front airbag
cannot perform its intended protective func-
tion, e.g. when a person is seated in the front- passenger seat.
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board. This poses an increased risk of injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
R the classification of the person in the front-
passenger seat is correct and the front-
passenger front airbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the person is seated properly with a cor-
rectly fastened seat belt.
R the front-passenger seat has been moved
as far back as possible.
If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the front- passenger seat may not be used. Do not
install a child restraint system on the front-
passenger seat. Have the automatic front-
passenger front airbag deactivation system
checked and repaired immediately at a quali-
fied specialist workshop. G
WARNING
Objects between the seat surface and the
child restraint system could affect the func-
tion of the automatic front-passenger front
airbag deactivation system. This could result
in the front-passenger front airbag not func-
tioning as intended during an accident. This
poses an increased risk of injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The

Important safety notes G
WARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an acci-
dent, heavy braking or sudden changes of
direction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g. in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after fitting a Top Tether belt. Observe the lock verificationindicator. Adjust the rear seat backrests so
that they are in an upright position.
If the rear seat backrest is not engaged and
locked, this will be shown in the multifunction display in the instrument cluster. A warning
tone also sounds.
