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
119
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.
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. 119

Park Assist Camera limitations
The Park Assist Camera may not be able to
detect all conditions in all situations and func-
tionality may therefore be limited.
The driver should be aware of the following limi-
tations for the Park Assist Camera:
WARNING Be extra cautious when
reversing if this symbol is
shown when a trailer, bike
carrier or similar is attached
and electrically connected
to the vehicle.
The symbol indicates that
the rear parking assist sensors are deacti-
vated and will not warn of any obstacles.
NOTE A bike carrier and other accessories mounted
on the rear of the vehicle can obscure the
camera's view.
Blind sectors There are "blind" sectors between the cameras' fields of
vision.
With 360° view selected, objects/obstacles may
not be detected if they are located in the "joints"
where the edges of the individual camera views
meet.
WARNING
Even if it seems as though only a fairly small
section of the screen image is obstructed, this
may mean that a relatively large sector is hid-
den and obstacles there may not be detected
until they are very near the vehicle.
Defective cameraIf a camera sector is dark and
contains this symbol, this indi-
cates that the camera is not
functioning properly.
See the following illustration for
an example. The vehicle's left-side camera is malfunctioning.
Dark camera sector
A dark camera sector may also be displayed in
the following situations, but without the defective
camera symbol:
a door is open
the tailgate is open
a rearview mirror is folded in
Lighting conditionsThe camera image is automatically adjusted
according to the current lighting conditions. This

DRIVER SUPPORT
408Parking with Park Assist Pilot
Park Assist Pilot (PAP 124
) helps the driver park
using three different steps. The function can also
help the driver pull out of a parking space.
NOTE The PAP function measures the space and
steers the vehicle – the driver's role is to:
keep close watch of the area around the
vehicle
follow the instructions on the center dis-
play
change gears (reverse/forward) – a
"ping" sound indicates when the driver
should change gears
regulate and maintain a safe speed
apply the brakes and stop. Information about the actions required by the
driver are provided in the center display using
symbols, graphics and/or text.
PAP can be activated if the following criteria have
been met after the engine is started:

No trailer is hitched to the vehicle
Your vehicle's speed is lower than 30 km/h
(20 mph).
NOTE The distance between the vehicle and parking
spots should be 0.5-1.5 meters (1.6-5.0 ft)
when PAP is looking for parking.
ParkingPAP parks the vehicle using the following steps:
1. The system searches for and measures
potential parking spaces.
2. The vehicle is steered while it is backing into the parking space.
3. The vehicle is positioned in the parking space (the driver may be prompted to shift
gears).
Searching for and measuring potential
parking spots
The function can be activated
in the center display's Function

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.

STARTING AND DRIVING
}}
457
This drive mode is optimized for maximum control
when driving at low speeds on very poor roads or
difficult terrain. It raises the chassis
3
, 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 3
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.

Loading recommendations (p. 598) 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.

STARTING AND DRIVING
472Preparing for a long trip
It is important to have the vehicle's systems and
equipment checked carefully before driving long
distances.
Check that:
the engine is running properly and that fuel
consumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning optimally
all lights are working ‒ adjust the headlight
height if the vehicle is carrying a heavy load
tire tread depth and air pressure are at cor-
rect levels. Change to snow tires when driv-
ing in areas where there is a risk of snowy or
icy roads
the start battery is sufficiently charged
the wiper blades are in good condition

It is important to check the vehicle before driving
in cold/snowy conditions to make sure it can be
driven safely.
Before the cold season arrives: Make sure the engine coolant contains 50%
antifreeze. This mixture helps protect the
engine from frost erosion down to
approx. -35 °C (-31 °F). Do not mix different
types of antifreeze as this could pose a
health risk.
Keep the fuel tank well filled to prevent con-
densation from forming.
Check the viscosity of the engine oil. Oil with
low viscosity (thinner oil) improves cold-
weather starting and reduces fuel consump-
tion when driving with a cold engine.
CAUTION Low-viscosity oil should not be used with hard
driving or in hot weather.

Check the condition and charge level of the
start battery. Cold weather places greater
demands on the start battery and reduces its
capacity.
Use washer fluid containing antifreeze to
help prevent ice from forming in the washer
fluid reservoir.
