WARNING
Remember that the car does not emit any
engine noise when it is only powered by the
electric motor and may therefore be difficult
to notice by children, pedestrians, cyclists and
animals. This applies in particular at low
speeds, such as in car parks.
WARNING
Do not leave the car in an unventilated area
with activated drive mode and the fuel-driven
engine switched off - automatic engine start
occurs at low energy level in the hybrid bat-
tery, and the exhaust gases could then cause
serious injury to people and animals.
HYBRID
This is the car's normal mode.
When the car starts, it is normally in

motor and fuel-driven engine - individually or in
An exception is if the car has been switched off in Off Road mode, then it will also start in Off Road mode.

parallel - and calculates the optimal use with
regard to performance, fuel consumption and
comfort. At higher speeds the ground clearance
is adjusted automatically to a lower level in order
to reduce wind resistance.
The capacity to run solely with the electric motor

battery's energy level and, for example, the need
for heating/cooling in the passenger compart-
ment.
If high power output is available, it is possible to
drive with electrical power alone. When the accel-
erator pedal is depressed, only the electric motor
is activated until a certain position is reached.
When this position is passed the internal com-
bustion engine starts.
Hybrid
The driver display for propulsion with both the electric
motor and internal combustion engine.
drive mode depends on the hybrid
The pointer in the driver display indicates how
much energy the car uses during driving, and the
small pointer between the lightning bolt and the
drop shows how much energy is available for use.
Read more about hybrid information in the driver
display in the section "Hybrid related information
in the driver display".
The internal combustion engine starts when the
energy level in the battery is insufficient for the
engine power that the driver requests with the
accelerator pedal.
The driver display also shows when energy is
returned to the battery (regenerated) during light
braking. More information on regeneration is
available in the section "Foot brake".
At low energy level (hybrid battery almost empty)
the battery's energy level must be maintained,
leading to the internal combustion engine star-
ting more often. Charge the hybrid battery from a
230 VAC socket with the charging cable or
