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 in the vehicle
Operator's Manual: R
Transporting the vehicle R

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 carrying
out general tasks, such as changing bulbs or
checking the coolant level.
Automatic switching off of the hybrid
drive system If components of the restraint system are acti-
vated during an accident, the hybrid drive sys-
tem 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 contact
with high voltage.

Restraint system warning lamp If the restraint system is disrupted, the high-
voltage on-board electrical system may not be
switched off in the event of an accident as inten-
ded.
G DANGER
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. Furthermore, in the
event of an accident, the vehicle's high-volt-
age electrical system may not be deactivated
as intended. You may be electrocuted if you
touch the damaged components of the vehi-
cle's high-voltage electrical system. 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. After an accident, switch off
the ignition immediately and remove the key
from the ignition lock.
A malfunction has occurred if the u restraint
system warning lamp: R
does not light up after the ignition is switched
on R
does not go out after a few seconds while the
combustion engine or hybrid system is run-
ning R
lights up again while the combustion engine
or hybrid system is running12

Overview of climate control systems
General notes Observe the notes and the recommended settings in the vehicle Operator's Manual. The windows
could otherwise fog up.
Climate control regulates the temperature and air humidity in the vehicle interior. Due to the elec-
trical refrigerant compressor, the "Cooling with dehumidification" function is also operational with-
out the combustion engine running. Optimum climate control is only achieved with the side windows
and roof closed.
The residual heat function can only be activated or deactivated with the ignition switched off
( Y
page 17).
The "Pre-entry climate control" function is available. Use this function to briefly preheat or ventilate
the driver's seat area or the entire vehicle interior before entering the vehicle. The air from the air
vents can also be pre-cooled.

tems
Switching cooling with air dehumidi-
fication on/off If you deactivate the "Cooling with air-dehumid-
ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly.
The "Cooling with air dehumidification" function
is available even when the engine is not running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selected.
