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

!
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
