Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 28). Hybrid vehicles
General notes
Hybrid technology combines a fuel-efficient
internal combustion engine with a powerful
electric motor. Important safety notes
Danger of electric shock G
DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the vehi-
cle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
When towing a vehicle after an accident, be
sure to observe the following sections:
R Transporting the vehicle (Y page 448)
R Towing the vehicle with both axles on the
ground (Y page 447) Read the safety instructions on towing and
tow-starting (Y
page 445). All components of the hybrid drive system are
marked with yellow warning stickers that
warn you of the danger of high voltage. The
cables of the vehicle's high-voltage electrical system are orange in colour.
The ignition must be switched off when car-
rying out general work, such as changing
bulbs or checking the coolant level.
Automatic switching off of the hybrid
drive system If components of the restraint system are
activated during an accident, the hybrid drive
system is automatically deactivated.
The hybrid drive system is not activated when
the vehicle is started if:
R an electrical short circuit is detected in the
hybrid drive system
R an electrical connection in the hybrid drive
system is disconnected
This ensures that you do not come into con-
tact with high voltage.
Manual switching off of the hybrid drive system The hybrid drive system can be deactivated
manually using the high voltage switch-off
device.44
Hybrid vehiclesSafety

!
To prevent damage to the hybrid drive
system please observe the following
instructions:
R only deactivate the hybrid drive system
manually in the following situations.
R work on the hybrid drive system may only
be carried out at a qualified specialist
workshop, even when it has been deac-
tivated manually.
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 transmission 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 transmission to position P.
Apply the electric parking brake
(Y page 220).
Secure the vehicle against rolling away
(Y page 465).
X To use the high-voltage switch-off
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.
If the hybrid drive system has been deactiva- ted 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 vehi-
cle standing idle for lengthy periods can
damage the high-voltage battery. If the
vehicle is idle for lengthy periods leave the Hybrid vehicles

Introduction to the restraint system
The restraint system can reduce the risk of
vehicle 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 50)
R adjust their seat and head restraint prop-
erly (Y page 121).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position .
You also have to make sure that an airbag can
inflate properly if deployed (Y page 53).46
Occupant safetySafety

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 example, 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 rele-
vant accident situation are deployed. How-
ever, seat belts and airbags generally do not
protect against objects penetrating the vehi-
cle from the outside.
Information on the restraint system operation
can be found under "Triggering of belt ten-
sioners and airbags" (Y page 62).
For more information about children travel-
ling with you in the vehicle, see "Children in
the vehicle" (Y page 65). 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 to
accommodate a person with disabilities, con- tact a Mercedes-Benz Service 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 a few 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. There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop.
Hybrid vehicles: G
DANGER
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. In addition, the vehicle's high-voltage electri-
cal system may not be deactivated as inten-
ded in the event of an accident. Touching
damaged components of the vehicle's high-
voltage electrical system could result in an
electric shock. There is an increased risk of
injury, possibly even fatal.
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. Occupant safety
