CAUTION Objects such as chains, thin and glossy poles
or low obstacles may end up in the "signal
shadow" and then go temporarily undetected
by the sensors – the pulsating tone may then
unexpectedly stop instead of becoming a
constant tone as expected.
The sensors cannot detect high objects, such
as protruding ramps.
• In such situations, pay extra attention and
maneuver/drive the vehicle very slowly or
stop the current parking maneuver –
there may be a high risk of damage to
the vehicle or other objects since infor-
mation from the sensors is not always
reliable in such situations.
CAUTION In some circumstances, the Park Assist Sys-
tem may produce false warnings due to exter-
nal sound sources with the same ultrasonic
frequencies as those the system works with.
Examples of such sources are horns, wet tires
on asphalt, pneumatic brakes, exhaust noise
from motorcycles, etc.
NOTE When a trailer hitch is configured with the
vehicle electrical system, the trailer hitch pro-
trusion is included when the function meas-
ures the distance to objects behind the vehi-
cle.

are located in the rearview mirrors.
The side cameras can show views along each
side of the vehicle.

• Park Assist Camera* (p. 386) Park Assist Camera trajectory lines
The Park Assist Camera uses trajectory lines
and fields on the screen to indicate the vehicle's
position in relation to its immediate surround-
ings. Example
121
of trajectory lines.
The trajectory lines show the anticipated trajec-
tory for the vehicle's outermost dimensions based
on the current position of the steering wheel to help simplify parallel parking, backing into tight
spaces or attaching a trailer.
The lines on the screen are projected as if they
were painted lines on the ground behind the
vehicle and are directly affected by the way in
which the steering wheel is turned. This enables
the driver to see path the vehicle will take, even if
he/she turns the steering wheel.
These lines also indicate the outermost limits that
any object (towbar, rearview mirrors, corners of
the body, etc.) extends out from the vehicle.
NOTE
•
When reversing with a trailer that is not
electrically connected to the vehicle, the
screen guide lines show the path the
vehicle will take – not the trailer.
• The screen does not show guide lines
when a trailer is electrically connected to
the vehicle's electrical system.
• Guide lines are not shown when zooming
in. 120

CAUTION•
Bear in mind that when the rearward
camera view is selected, the screen only
shows the area behind the vehicle – pay
attention to the sides and front of the
vehicle when steering while reversing.
• The same applies to the reverse – pay
attention to what is happening with the
rear parts of the vehicle when the front
camera view is selected.
• Note that the guide lines show the short-
est path – pay extra attention to ensure
that the vehicle sides do not come in
contact with/travel over anything when
steering while driving forward or that the
vehicle front moves toward/over anything
when steering while reversing.Trajectory lines in 360° view* 360° view with trajectory lines

In the 360° view, trajectory lines are shown
behind, in front of, or to the sides of the vehicle,
depending on the direction of travel.
• When driving forward: Front lines
• When backing up: Side lines and rear lines.
When the front or rear camera is selected, the
trajectory lines will be shown regardless of the
vehicle's direction of travel.
With a side camera selected, the trajectory lines
will only be shown if the vehicle is backing up.Trajectory lines for a towbar* Towbar with trajectory line

the rear view 123
.
Camera view when manually starting
the camera
Start the Park Assist Camera
using this button in the center
display's Function view.
The screen will first show the
most recently used camera
view. However, each time the
engine is started, the previous side view will be
replaced by the 360° view and a previously dis-
played zoomed-in rear view will be replaced by
the regular rear view.
Automatically deactivating the cameraFront view switches off when the vehicle's speed
reaches 25 km/h (16 mph) to help avoid dis-
tracting the driver. It will be automatically reactiva-
ted if the vehicle's speed falls below 22 km/h
(14 mph) within 1 minute as long as the vehicle's
speed has not exceeded 50 km/h (31 mph). Other camera views switch off at 15 km/h
(9 mph) and are not reactivated.

Always use the parking brake when parking on a
hill.
WARNING Always apply the parking brake when parking
on an incline. Selecting a gear or putting the
automatic transmission in P may not be suffi-
cient to keep the vehicle stationary in all sit-
uations.
If the vehicle is pointing uphill: • Turn the front wheels so they are pointing
away from the curb.
If the vehicle is pointing downhill:
• Turn the front wheels so they are pointing
toward the curb.
Heavy load uphill
Heavy loads, such as a trailer, could cause the
vehicle to roll backward when the parking brake
is released automatically on steep uphill gradi-
ents. To help avoid this, pull the control upward
while you are driving away. Release the control
when the vehicle gains traction.

OFF ROAD
• Maximizes the vehicle's ability to traverse dif-
ficult terrain or poor roads.
In this mode, ground clearance 4
is high, steering
is light, and all-wheel drive and Hill Descent
Control are activated.
This drive mode is only available at low speeds,
up to 40 km/h (25 mph). If this speed is excee-
ded, Off road mode will be cancelled and AWD
mode will be activated instead.
All-wheel drive requires both the combustion and
electric motor to be in continuous operation,
which results in higher fuel consumption.
In Off road mode, a compass will be displayed
between the speedometer and the tachometer in
the instrument panel. The permissible speed
range will be shown in the speedometer.
This drive mode is optimized for maximum control
when driving at low speeds on very poor roads or
difficult terrain. It raises the chassis 4
, reduces
driveline throttle response, and locks the vehicle
in all-wheel drive. The Hill Descent Control func-
tion facilitates controlled driving on steep down-
grades.NOTE This drive mode is not designed to be used
for normal street driving.
NOTE
Due to the increased ground clearance, if the
OFF ROAD mode was selected when the
engine was switched off, the suspension will
lower when the engine is restarted.
CAUTION
Do not use the OFF ROAD drive mode when
towing a trailer without an electrical connec-
tion. This could result in damage to the pneu-
matic suspension system's bellows.
AWD
•
Improves the vehicle's traction and handling
by increasing all-wheel drive.
This drive mode locks the vehicle in all-wheel
drive. An optimal distribution between front and
rear axle torque helps provide the best possible
control, stability and traction, e.g. on slippery
roads or when towing a heavy trailer or another
vehicle. The AWD drive mode is always available
regardless of the hybrid battery's charge status. 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 accord-
ing to the road surface, and can activate the elec-
tric motor or start the combustion engine as nee-
ded.
POWER
•
Power mode is designed to provide sportier
driving characteristics and a faster accelera-
tion response.
This drive mode maximizes 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, suspension is stiffer and ground clearance
is lower 4
to help reduce body roll when cornering.
Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
This drive mode is optimized for maximum per-
formance and throttle response. It changes the
throttle response, gear shifting program and
turbo boost system. Chassis settings and steer-
ing and brake response are also optimized. The
Power drive mode is always available regardless
of the hybrid battery's charge status. 4

•Leveling control* and suspension (p. 450)
• Loading recommendations (p. 586) Low Speed Control
The low-speed function, Low Speed Control
(LSC), facilitates and improves control and trac-
tion on rough roads and slippery surfaces, e.g.
when towing a trailer on grass or up boat ramps.
The function is included in the Off Road drive
mode.
Low Speed Control is designed for driving on
rough roads and when towing trailers at low
speeds, up to approximately 40 km/h (25 mph).
When driving at low speeds, LSC prioritizes low
gears and all-wheel drive to help avoid wheel spin
and improve traction on all wheels. The accelera-
tor pedal will be less responsive to improve trac-
tion and speed control at low speeds.
The function is activated together with Hill
Descent Control (HDC), which makes it possible
to control speed going down steep hills using the
accelerator pedal and reduces the need to use
the brake pedal. The system makes it possible to
maintain a low and uniform speed when driving
down steep hills.
