Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops (Y page 29). 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.
Following an accident, do not touch any high- voltage components and never modify the
vehicle'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 437)
R Towing the vehicle with the rear axle raised
(Y page 437)
R Towing a vehicle with both axles on the
ground (Y page 436)
Read the safety instructions on towing and
tow-starting (Y page 435). All components of the hybrid 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 color.
The ignition must be switched off when car-
rying out general tasks, such as adding
washer fluid to the windshield washer system or checking the coolant level.
Automatic deactivation of the hybrid
system G
DANGER
If the restraint system is malfunctioning, indi- vidual restraint system components may be
triggered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This could
affect Emergency Tensioning Devices or air
bags, for example. The vehicle's high-voltage
electrical system may also not be deactivated
as intended in the event of an accident. You
could suffer an electric shock if you touch the damaged components of the vehicle's high- 46

voltage electrical system. This poses an
increased risk of injury or even fatal injury.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. Immediately switch off the ignition and remove the SmartKey from the ignition
lock after an accident.
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 one of the hybrid system’s electrical con-
nections 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.
i 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(Y page 197).
Depress the electric parking brake
(Y page 222).
Secure the vehicle against rolling away
(Y page 466).
X To use the high-voltage switch-off
device: open the trunk lid.
X Lift the trunk floor upwards (Y page 377).
X Remove the right-hand paneling in the
trunk. X
Press release clip :in the direction of the
arrow and pull it out.
X Pull the high voltage switch-off device ;
apart until it engages in the stop position.
If the hybrid system has been deactivated due to reasons mentioned above, have it checked
at a qualified specialist workshop before
reactivation. Hybrid vehicles
47Safety Z

High-voltage battery
G
WARNING
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. 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 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.
Hybrid vehicles: 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 proc-
ess, switch off all electrical consumers, e.g.
the automatic climate control or the seat
heating.
Plug-in hybrid vehicles: if the vehicle is
idle for lengthy periods leave the high-volt- age battery connected to a charging sta-
tion.
PLUG-IN HYBRID vehicles: charging the high-
voltage battery (Y page 209).
Engine compartment Before opening the hood:
X Apply the electric parking brake.
X Shift the automatic transmission to park
position P. X

tive Brake System)
The Recuperative Braking System supports
you when braking with an electronically-con-
trolled brake boost mode and enables the
recovery of kinetic energy (recuperation). G
WARNING
If the Recuperative Braking System malfunc-
tions, braking resistance may be reduced and brake pedal travel may be longer than usual. If
you subsequently depress the brake pedal as usual, the braking effect may not be sufficient.
There is a risk of an accident.
In the event of this malfunction, continue to
depress the brake pedal. Stop the vehicle in
accordance with the traffic conditions. If nec-
essary, contact a qualified specialist work-
shop.

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 restraint system is malfunctioning, restraint system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury. Have the restraint system checked and
repaired in a qualified specialist workshop as soon as possible.

Rear seat belt buckle extenders
The seat belt extender is an integral part of
the PRE-SAFE ®
convenience function. It is
used on the outer rear seats.
Always ensure that it is possible to move the
belt buckle freely. Always stow objects in the
vehicle correctly.
To assist you in finding the seat belt buckle
and fastening the seat belt:
R the belt buckle moves forwards to a con-
venient position
R the belt buckle is illuminated
After the seat belt is fastened, the belt buckle returns to its normal position. The seat belt
then lies tight across the lap and thorax areas.
Incorporation into the PRE-SAFE ®
system:
the belt buckle is lowered quickly in certain
hazardous situations. This pre-tensions the
seat belt.
Incorporation into the automatic meas-
ures after the accident: in this situation, the
belt buckle is illuminated and extended after
a rear door is opened.
Releasing seat belts !
Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam- aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop. X
Press release button :, hold belt
