Starting and stopping the
combustion engine in Twin Engine
vehicles
An advanced control system determines the
distance that the vehicle can be driven on the
combustion engine, electric motor, or both at
the same time. When driving on only the
electric motor, the vehicle may automatically
start the combustion engine due to outside
circumstances, e.g. low ambient tempera-
tures. This is completely normal. The com-
bustion engine will also always start when
the hybrid battery is nearly fully discharged.
Climate settings at low temperatures
At low ambient temperatures, the combustion
engine will sometimes start automatically to
help achieve the desired passenger compart-
ment temperature and air quality. The amount
of time the combustion engine is running can
be affected by
lowering the temperature
•
reducing blower speed
•
activating
Pure
drive mode.
•
Using the electric motor in hot or cold
weather
At very low or high ambient temperatures, the
electric motor's driving range and power may
be reduced and affect how often the combus-
tion engine automatically starts.
Emission control system
To help ensure that the emission control sys-
tem is as energy-efficient as possible, the
combustion engine will run for several minutes
after it is started. The amount of time the com-
bustion engine needs to be used varies
depending on the temperature of the three-
way catalytic converter.
WARNING
California Proposition 65
Operating, servicing and maintaining a pas-
senger vehicle can expose you to chemi-
cals including engine exhaust, carbon mon-
oxide, phthalates, and lead, which are
known to the State of California to cause
cancer and birth defects or other reproduc-
tive harm. To minimize exposure, avoid
breathing exhaust, do not idle the engine
except as necessary, service your vehicle in
a well ventilated area and wear gloves or
wash your hands frequently when servicing
your vehicle. For more information go to

vehicle.

STARTING AND DRIVING
Drive modes
Drive modes affect the vehicle's driving cha-
racteristics in different ways to enhance and
simplify the driving experience in certain
types of situations.
Drive modes enable easy access to the vehi-
cle's many functions and settings in different
driving situations. Each drive mode is adapted
to help optimize driving characteristics.

Select the drive mode that is adapted to the
current driving conditions. Keep in mind that
not all drive modes are available in all situa-
tions.

WARNING
Keep in mind that the vehicle does not emit
any engine noise when using the electric
motor and may therefore be difficult to
detect for children, pedestrians, cyclists or
animals. This is particularly true at low
speeds, e.g. in parking lots.
