HYBRID INFORMATION

General information about Twin
Engine
Twin Engine runs like a regular car, but certain
functions differ from a car that only runs on pet-
rol or diesel. The electric motor drives the car
mostly at low speeds, the petrol engine at higher
speeds, as well as during more active driving.
The driver display shows some information that is
unique to the Twin Engine - charging information,
selected drive mode, distance to empty battery as
well as the hybrid battery's charge level.
It is possible to set the car in different drive
modes while driving, e.g. electric operation only
or, when power is required, both electric motor
and petrol engine. The car calculates an optimal
combination of drivability, driving experience,
environmental impact and fuel economy accord-
ing to the drive mode selected.
In order that the car should have optimal function
it is important that the hybrid battery with associ-
ated electrical drive systems, as well as the petrol
engine and its drive systems, have the correct
operating temperature. Battery capacity may be
reduced considerably if the battery is too cold or
too hot. Preconditioning prepares the car's drive
systems and the passenger compartment before
departure so that both wear and energy needs
during the journey are reduced. The range for the
hybrid battery increases.
The hybrid battery which drives the electric motor
is charged via a charging cable but can also be
charged by gentle braking and engine braking in
gear position B . The hybrid battery can also be
charged by the car's engine.
Important to know
Car without power
Bear in mind that important functions such as the
brakes and power steering are inoperable when
the car is without power.
WARNING
In a de-energised car with the electric motor
and fuel-driven engine switched off it is not
possible to brake the car.
Towing not permitted
Towing the Twin Engine is not permitted since
this damages the electric motor.
Exterior engine noise
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 is especially true at low speeds,
such as in car parks.
High-voltage current
WARNING
Several components in the car work with
high-voltage current that could be dangerous
in the event of incorrect intervention. These
components, and all orange-coloured cables,
must only be handled by qualified personnel.
Do not touch anything that is not clearly descri-
bed in the owner's manual.
