Pure
Uses the electric motor only, with the low-
est possible energy consumption and car-
bon dioxide emissions.
This drive mode prioritizes the use of the
hybrid battery. Certain climate system func-
tions are reduced to provide the longest dis-
tance using only electricity.
Pure
mode is available when the hybrid bat-
tery is sufficiently charged. Even in
mode, the combustion 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 adapted for the longest
possible driving distance with electric propul-
sion and is primarily intended for use in city
driving.
Pure
helps provide the lowest possi-
ble consumption even when the hybrid battery
is fully discharged. ECO climate is activated to
control the climate in the passenger compart-
ment, and in slippery road conditions slightly
more wheel spin may be permitted before all-
wheel drive is automatically activated.
ECO Climate
In
Pure
mode, ECO climate is automatically
activated in the passenger compartment to
help reduce energy consumption.
NOTE
When the
Pure
settings for certain climate system and
electricity consuming functions are
reduced. Some of these settings can be
Pure
reset manually, but full functionality will
only be restored by leaving
adapting the
climate system functionality.
If condensation forms on the windows, tap the
max defroster button, which will function nor-
mally.
Constant AWD
Improves the vehicle's traction and han-
dling by increasing all-wheel drive.
This drive mode locks the vehicle in all-wheel
drive. An adapted distribution between front
and rear axle torque provides effective control,
stability and traction, e.g. on slippery roads or
when towing a heavy trailer or another vehicle.
The
Constant AWD
available regardless of the hybrid battery's
charge status.

STARTING AND DRIVING
Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
In the other drive modes, the vehicle automati-
cally adapts the need for all-wheel drive
according to the road surface, and can acti-
vate the electric motor or start the combustion
engine as needed.
Power
The vehicle gets sportier driving characte-
ristics and a faster acceleration response.
This drive mode adapts the combined power
from the combustion engine and the electric
motor by providing power to both the front
and rear wheels. Gear shifting will be faster
and more distinct and the transmission will
prioritize gears with a higher traction force.
Steering response is faster and suspension is
stiffer.
Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
