When shutting off
If the function is active and holding the
vehicle stationary using the normal
brakes (A symbol lit), the brake pedal
must be depressed while pressing the
button in order to deactivate Auto-hold.
The function will remain off until it is reactiva-
ted.
When Auto-hold is switched off, Hill Start
Assist (HSA) will remain active to help pre-
vent the vehicle from rolling backward when
starting up a hill.

Auto-hold brakes (p. 446) Hill Start Assist
The function for assisting when starting the vehi-
cle on inclines, Hill Start Assist (HSA), helps
prevent the vehicle from rolling backward when
starting on an uphill gradient. When backing up
a hill, HSA helps prevent the vehicle from rolling
forward.
The function retains pressure from the brake
pedal in the brake system for several seconds
after the brake pedal has been released.
This temporary braking effect is released after a
few seconds or when the driver begins driving.
Hill Start Assist is available even if the Auto-hold
brake function is switched off.

Brakes (p. 439) Braking assist after a collision
In a collision in which the activation level is
reached for the pyrotechnic seat belt tensioners
or airbags, or if a collision with a large animal is
detected, the vehicle's brakes will be automati-
cally activated. This function is intended to help
prevent or reduce the effects of any subsequent
collision.
After a serious collision, it may no longer be pos-
sible to control and steer the vehicle. In order to
avoid or mitigate a possible further collision with
a vehicle or an object in the vehicle's path, the
brake assist system is activated automatically to
help stop the vehicle safely.
The brake lights and hazard warning flashers are
activated during braking. When the vehicle has
stopped, the hazard warning flashers will con-
tinue to flash and the parking brake will be
applied.
If braking is not appropriate, e.g. if there is a risk
of being hit by passing traffic, the driver can over-
ride the system by depressing the accelerator
pedal.
This function assumes that the brake system is
intact after a collision.
Brake assist is part of the Rear Collision Warning
and Blind Spot Information safety systems.

Gear selector positions for
automatic transmissions
In vehicles with an automatic transmission, the
system selects the optimal gear for the current
driving conditions. The transmission also has a
manual mode.
The instrument panel shows which gear is cur-
rently in use:
P
, R, N, D or B.
For manual shifting, the gear indicator in the
instrument panel displays the gear currently
being used (1-8).
Selecting gearsThe gear selector is a shift-by-wire selector,
where shifting is done electronically instead of
mechanically. This makes shifting easier and the
gear positions more distinct. Select gears by moving the spring-loaded, non-
locking gear selector forward or backward.
Gear selector positions
Park - P
Park is activated using the P button located next
to the gear selector. Select P when the vehicle is parked or when star-
ting the engine. The vehicle must be stationary
when Park is selected.
To move to another gear from Park, the brake
pedal must be depressed and the ignition in
mode II.
When parking – apply the parking brake before
shifting to Park.
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.
NOTE The gear selector must be in the P position
before the vehicle can be locked and the
alarm set.

||STARTING AND DRIVING
* Option/accessory.
450 Help functions
The system will automatically shift to P:
if the ignition is switched off while D or R is
selected.
if the driver unbuckles the seat belt and
opens the driver's door while the vehicle is
running with the gear selector in a gear other
than P.
To park a vehicle with an unbuckled seat belt and
open door – end P mode by shifting to R or D
again.
The system will not automatically shift to P if the
ignition is switched off while the gear selector is
in the neutral position (N). This is to make it pos-
sible to wash the vehicle in an automatic car
wash in which the vehicle is pulled forward on
rolling wheels.
Reverse - R
Select R when backing up. The vehicle must be
stationary when Reverse is selected.
Neutral - N
No gear is selected and the engine can be
started. Apply the parking brake if the vehicle is
stationary with the gear selector in N.
To move the gear selector from Neutral to
another gear, the brake pedal must be depressed
and the ignition in mode II.
D drive mode
D is the normal driving gear position. The trans-
mission shifts up or down automatically depend- ing on acceleration and speed. The vehicle must
be stationary when the gear selector is moved
from R to D.
Brake - B
B can be selected at any time during a drive. In B
mode, the engine braking function is activated
when the accelerator pedal is released, which
helps charge the hybrid battery. This offers addi-
tional opportunities to recharge the hybrid bat-
tery, since the battery is charged even when the
brake pedal is not depressed. B mode in the instrument panel.
From B mode, it is possible to manually shift to
lower gears. The currently selected gear (1-8) will
be displayed in the instrument panel.
Pull the gear selector backward once to shift
down one gear.
Pull the gear selector backward again to shift
down to lower gears. To shift manually to a higher gear, the vehicle
must be equipped with steering wheel paddles*.
Push the gear selector forward to return to D
mode.
For smooth shifting and engine performance, the
transmission will shift down automatically if the
vehicle's speed becomes too low for the selected
gear.

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.

Preconditioning
Whenever possible, precondition the vehicle
before driving by connecting the charging
cable to an electrical outlet.
Avoid parking the vehicle somewhere where
the interior will become too hot or too cold
while the vehicle is parked. If possible, park
the vehicle in a climate-controlled garage.
During a short drive after passenger com-
partment preconditioning, turn off the pas-
senger compartment fan or the air condition-
ing in a hot climate.
If preconditioning is not possible when it is
cold outside, use seat and steering wheel
heating first. Avoid heating the entire pas-
senger compartment to reduce the amount
of current being taken from the hybrid bat-
tery.
Driving
Choose the Pure drive mode to help mini-
mize electric power consumption.
Maintain a steady speed and a generous fol-
lowing distance to traffic ahead to minimize
braking. This drive mode has the lowest
power consumption.
Balance energy requirements using the
accelerator pedal. Use the indicator on the
instrument panel to see available electric
power and avoid starting the combustion
engine unnecessarily. The electric motor is more effective than the combustion engine,
especially at low speeds.
When braking is necessary, brake gently
using the brake pedal. This will help recharge
the hybrid battery. A regenerative function is
integrated in the brake pedal and can be
augmented by the electric motor's braking
capacity when the gear selector is in mode
B.
Higher speeds increase energy consumption
- air resistance increases with speed.
Activate the Hold function in the Function
view at high speeds when traveling farther
than is possible using the hybrid battery's
capacity.
Whenever possible, avoid using the Charge
function to charge the hybrid battery. Charg-
ing the battery using the combustion engine
increases fuel consumption and carbon diox-
ide emissions.
In a cold climate, reduce heating of the wind-
shield/rear window, mirrors, seats and the
steering wheel.
Maintain the correct pressure in the tires and
check pressure regularly.
The type of tires used could affect energy
consumption - consult a retailer for advice on
suitable tires.
Remove unnecessary items from the vehicle
- the heavier the load, the higher the fuel
consumption.
Roof loads increase air resistance and
increase fuel consumption. Remove roof
boxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
Do not keep the vehicle still on an upward
gradient by using the accelerator pedal. Use
the brakes instead.

(p. 479) Trailer Stability Assist*
Trailer Stability Assist (TSA 8
) is a function
designed to help stabilize a vehicle that is tow-
ing a trailer when the vehicle and trailer have
begun to sway. The function is part of the Elec-
tronic Stability Control system ESC 9
.
Reasons for swayingA vehicle towing a trailer may begin to sway for
various reasons. Normally this only occurs at high
speeds. However, if the trailer is overloaded or
unevenly distributed, e.g. too far back, there is a
risk of swaying even at low speeds.
Swaying may be caused by factors such as:
The vehicle and trailer are hit by a sudden,
strong crosswind.
The vehicle and trailer are traveling on an
uneven road or over a bump.
Sudden movements of the steering wheel.
Once swaying has begun, it can be difficult or
impossible to stop it. This makes the vehicle and
trailer difficult to control and there is a risk of
swerving into oncoming traffic or driving off the
road.
Trailer Stability Assist functionTrailer Stability Assist continuously monitors the
vehicle's movements, particularly lateral move- ments. If swaying is detected, the brakes are
applied individually on the front wheels, which has
a stabilizing effect on the vehicle and trailer. This
is often enough to enable the driver to regain
control of the vehicle.
If the Trailer Stability Assist function's first
attempt is not adequate to stop the swaying
motion, the brakes are applied on all wheels and
engine power is temporarily reduced. As the
swaying motion begins to decrease and the vehi-
cle and trailer have once again become stable,
TSA stops regulating the brakes/engine power
and the driver regains control of the vehicle.
NOTE
Trailer Stability Assist is deactivated if the
driver selects the sport mode by deactivating
ESC in the center display's menu system. Trailer Stability Assist may not intervene if the
driver tries to compensate for the swaying motion
by moving the steering wheel rapidly, because
the system will then not be able to determine if it
is the trailer or the driver causing the swaying.

Recovery
This section refers to transporting the vehicle
with a tow truck or similar vehicle.
Call a professional towing service for assistance.
In certain conditions, the towing eyelet can be
used to pull the vehicle onto a flatbed tow truck.
CAUTION Note that vehicles with Twin Engine must
always be towed raised with all wheels on the
tow truck.
For vehicles equipped with leveling control*:
If the vehicle is equipped with pneumatic suspen-
sion, this feature must be turned off before the
vehicle is lifted onto a tow truck. Turning off the
function in the center display.
1. Tap Settings in the Top view.
2.

Tap My Car Parking Brake and
Suspension .
3. Select Disable Leveling Control.
The vehicle's location and ground clearance
determine if it can be lifted onto a tow truck. If
the incline of the tow truck is too steep or if the
ground clearance under the vehicle is insufficient,
attempting to pull it up may result in damage. In
this case, the vehicle should only be lifted with
the tow truck's lifting equipment.
WARNING No person or object should be behind the tow
truck when the vehicle is lifted onto the bed
of the truck.

CAUTION
When not in use, the jack* should be kept
in its storage compartment under the
cargo compartment floor.
The jack provided with your vehicle is
intended to be used only in temporary sit-
uations such as changing wheels in the
event of a flat tire. Only the jack that
came with your particular model should
be used to lift the vehicle. If the vehicle
needs to be lifted more frequently or for a
prolonged period, using a garage jack or
hoist is recommended. Always follow this
device's instructions for use.
WARNING
Apply the parking brake and put the gear
selector in the Park (P) position.
Block the wheels standing on the ground,
use rigid wooden blocks or large stones.
Check that the jack is not damaged, the
threads are properly lubricated and it is
free from dirt.
Be sure the jack is on a firm, level, non-
slippery surface and that it is upright and
not leaning.
The jack must correctly engage in the
jack attachment.
No objects should be placed between the
base of the jack and the ground, or
between the jack and the attachment bar
on the vehicle.
Never let anyone remain in the vehicle
when it is raised on a jack.
If a tire must be changed near passing
traffic, make sure all passengers move to
a safe location.
Use a jack intended for the vehicle when
changing a tire. For any other job, use
stands to support the vehicle.
Never crawl under or allow any part of
your body to be extended under a vehicle
supported by a jack.
