OFF ROAD
•
Maximise the car's traction when driving in
difficult terrain and on poor roads.
The drive mode provides high ground clearance
steering is light, all-wheel drive and the function
for low speed control with hill descent control
(Hill Descent Control) are activated.
The drive mode is only available at low speeds, up
to 40 km/h (25 mph). If this speed is exceeded,
Off road mode is cancelled and the AWD drive
mode is activated instead.
To be able to drive all four wheels, the internal
combustion engine and electric motor run contin-
ually, which results in increased fuel consump-
tion.
In the Off road mode the driver display has a
compass between the speedometer and tachom-
eter. The speedometer shows the range for
speed limitation.
The drive mode is optimised for maximum con-
trollability at low speeds in poor road conditions
or difficult terrain. It raises the chassis
the driveline's throttle response and locks the car
in all-wheel drive. The Hill Descent Control func-
tion facilitates controlled driving on steep
descents.
Applies with air suspension.

NOTE
The driving mode is not designed to be used
on public roads.

NOTE
If the car is switched off in OFF ROAD mode,
and therefore has high ground clearance, the
car is lowered next time it is started.
IMPORTANT
The OFF ROAD drive mode must not be used
while driving with a trailer without trailer con-
nector. Otherwise, there is a risk of damage to
the air bellows.
AWD
•
Improve the car's roadholding and traction
with enhanced all-wheel drive.
The drive mode locks the car in all-wheel drive.
An optimal distribution between the front and
4
, reduces
rear axle torque gives the best traction, stability
and roadholding, for example on slippery roads,
when driving with a heavy trailer, or when towing.
AWD drive mode is always available regardless of
the battery's state of charge.
Both the internal combustion engine and electric
motor are engaged in order to drive all four
STARTING AND DRIVING
wheels, which results in increased fuel consump-
tion.
In the car's other drive modes, the car automati-
cally adapts the need for all-wheel drive to the
road surface, and can engage the electric motor
or start the internal combustion engine when
necessary.
POWER
•
Power mode means that the car has sportier
characteristics and faster response to accel-
erating.
The drive mode maximises the combined power
from the internal combustion engine and electric
motor by means of the car being driven by both
front and rear wheels. The gear changes become
faster and more distinct, and the gearbox prioriti-
ses a gear with greater traction. Steering
response is faster, shock absorption is harder
4
and a lower ground clearance means that the
body follows the roadway in order to reduce roll
during cornering.
Both the internal combustion engine and electric
motor are engaged in order to drive all four
wheels, which results in increased fuel consump-
tion.
