HYBRID
This is the default mode in which the electric
•
motor and combustion engine work together.
The vehicle starts in Hybrid mode. The control
system uses both the electric motor and the gas-
oline engine - separately or in tandem - and cal-
culates optimal utilization with regard to perform-
ance, fuel consumption and comfort. Driving
capacity on the electric motor alone is deter-
mined by factors such as the hybrid battery's
charge level, the need for heat/cooling in the
passenger compartment, etc.
If there is sufficient charge in the battery, it is
possible to drive solely on electric power. When
the accelerator pedal is pressed, only the electric
motor will be activated until the battery reaches a
certain charge level. Above this level, the current
in the battery cannot supply the power requested
by the accelerator pedal and the combustion
engine will start.
When the hybrid battery's charge level is low, the
combustion engine will start more frequently to
save the remaining current in the battery. Charge
the hybrid battery from a 120-240 volt outlet
using a charging cable, or activate
Function view to reset the option of only using
the electric motor.
This drive mode is designed for low energy con-
sumption with an optimized mix between the
electric motor and gasoline engine, without com-
promising on climate comfort or driving experi-
ence. When faster acceleration is requested by
the driver, the electric driveline will be utilized to
help provide maximum additional power. The
vehicle also monitors the driving conditions and
automatically engages all-wheel drive if neces-
sary. All-wheel drive and extra electric power are
always available regardless of the battery's
charging status.
Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge will
be displayed in the instrument panel. The gauge
will indicate the amount of electrical current
required when the driver depresses the accelera-
tor pedal. The marker between the lightning and
the drop shows how much current is available.
Charge in
The instrument panel gauge when both the electric
motor and the combustion engine are being used.
The instrument panel also shows how
much current is being restored to the
battery (regenerated) during light brak-
ing.
STARTING AND DRIVING
PURE
Uses the electric motor only, with the lowest
•
possible energy consumption and carbon
dioxide emissions.
This drive mode maximizes the use of the hybrid
battery. Certain climate system functions are
reduced to provide the longest distance using
only electricity.
Pure mode is available when the hybrid battery is
sufficiently charged. Even in Pure mode, the com-
bustion engine will start if the charge level in the
battery gets too low. The combustion engine will
also start
if the vehicle's speed goes above 125 km/h
•
(78 mph)
if the driver requests more power than the
•
electric motor can provide
if factors such as cold weather affect the
•
system or components.
This drive mode is optimized for maximum driving
distance with electric propulsion and is primarily
intended for use in city driving. Pure helps pro-
vide the lowest possible consumption even when
the hybrid battery is fully discharged. ECO climate
is activated to control the climate in the passen-
ger compartment, and in slippery road conditions
slightly more wheel spin may be permitted before
all-wheel drive is automatically activated.
