230 Parking climate
The passenger compartment climate can be pre-
conditioned or maintained when the vehicle is
parked. For full functionality, the vehicle's charg-
ing cable must be plugged in. Preconditioning and the climate comfort retaining func-
tion are controlled from the Parking climate tab in the
center display's Climate view.

(p. 236) Preconditioning
Preconditioning the vehicle before driving can
help reduce wear and reduce energy consump-
tion during a trip.
Preconditioning can be started immediately or
started at a preset time using a timer.
The function utilizes several of the vehicle's sys-
tems:
• In cold weather, the high-voltage coolant
heater (HVCH) heats the passenger com-
partment to a comfortable temperature.
• In warm weather, air conditioning cools the
passenger compartment to a comfortable
temperature.
• The electrically heated steering wheel* and
seats* can be activated.
• Heating for the windshield, rear window and
door mirrors are automatically activated as
needed.
During preconditioning in a hot climate, conden-
sation from the air conditions may drip under the
vehicle. This is normal.

NOTE Preconditioning is only available when the car
is connected to an electrical outlet. A charg-
ing post that is not always active, for example
because of a timer, can cause loss of function
for preconditioning.
If the car is not connected to an electrical
socket it is still possible in a warm climate to
achieve brief cooling of the passenger com-
partment by direct starting preconditioning.
NOTE
During preconditioning of the passenger
compartment, the vehicle works to reach a
comfortable temperature and not the tem-
perature set in the climate system.

||KEY, LOCKS AND ALARM
* Option/accessory.
244 For keyless use, a remote key or the Key Tag
must be within the shaded areas shown in the
illustration, i.e. a semicircle with a radius of
approx. 1.5 meter (5 feet) along the sides of the
vehicle or approx. 1 meter (3 feet) from the tail-
gate.
NOTE
The functions of the remote control key can
be disrupted by ambient radio waves, build-
ings, topographical conditions, etc. The vehi-
cle can always be locked/unlocked using the
key blade.
If the remote key is removed from the
vehicle
If the remote key is removed from the
vehicle while the engine is running, the
warning message
Vehicle key not
found Removed from vehicle will be
displayed in the instrument panel and an audible
signal will sound when the last door is closed. The message will disappear when the key is
returned to the vehicle and the O button on the
right-side steering wheel keypad is pressed or
when the last door is closed again.

The battery in the remote key must be replaced
when it is discharged.
NOTE All batteries have a limited service life and
must eventually be replaced (does not apply
for Key Tag). The battery's service life varies
depending on how often the vehicle/key is
used.
The remote key battery should be replaced if:
the information symbol illuminates and
the message Vehicle key bat. low

the instrument panel and/or
• the locks do not react after several attempts
to lock or unlock the vehicle using the
remote key within approx. 20 meter (65 feet)
from the vehicle.
NOTE Move closer to the vehicle and try to unlock it
again.

DRIVER SUPPORT
* Option/accessory.
272 Driver support systems
The vehicle is equipped with a number of driver
support systems that can provide the driver with
active or passive assistance in various situations.
The system can, for example, help the driver
maintain a set speed or a set time interval to the
vehicle ahead, help prevent a collision by warning
the driver and applying the brakes, or assist the
driver while parking.
Some of the systems are standard and others are
options. This also varies from market to market.

resistance
Speed-dependent power steering increases the
steering wheel resistance in pace with the vehi-
cle's speed to give the driver an enhanced feel-
ing of control and stability.
Steering may feel stiffer on highways. When
parking and at low speeds, it will be easier to
move the steering wheel.
NOTE In some situations, the power steering may
become too hot and require temporary cool-
ing – during such time the power steering will
work at reduced output and the steering
wheel may feel more difficult to move.
In parallel with the temporarily reduced steer-
ing assistance, the driver display shows a
message as well as a STEERING WHEEL
symbol.

DRIVER SUPPORT
* Option/accessory.273
WARNINGWhile the power steering is working at
reduced power, the driver support functions
with steering assistance are not available.
In such a situation, the driver display shows
the
Power steering failure or Power
Steering Assist Temporarily Reduced message, combined with a STEERING
WHEEL symbol.
Changing the level of steering wheel
resistance*
To change the level of steering wheel resistance,
see the description of the INDIVIDUAL option
under "Available drive modes" in the "Drive
modes" section.
On models not equipped with drive mode con-
trols and the INDIVIDUAL option, steering wheel
resistance can instead be set in the center dis-
play's Top view under:
Settings My Car Drive Modes
Steering force
Steering wheel resistance settings cannot be
accessed when turning at speeds above
10 km/h (6 mph).

Control
The Roll Stability Control (RSC 1
) system helps
minimize the risk of a rollover in the event of e.g.
a sudden evasive maneuver or if the vehicle
begins to skid.
The RSC system monitors the lateral angle at
which the vehicle is leaning and registers any
changes. Using this information, the system cal-
culates the likelihood of a rollover. If there is an
imminent risk of a rollover, Electronic Stability
Control is activated, engine torque is reduced and
brakes are applied to one or more of the wheels
until the vehicle has regained stability.

274 Electronic Stability Control
The Electronic Stability Control (ESC 2
) function
helps the driver avoid skidding and improves the
vehicle's directional stability.
This symbol will be displayed in
the instrument panel when the
ESC system is intervening.
When the ESC has intervened
to apply the brakes, a pulsing
sound may be heard and the
vehicle may accelerate more slowly than expec-
ted when the accelerator pedal is depressed. The ESC system consists of the following sub-
functions:
•
Stability control 3
• Spin control and active yaw control
• Engine drag control
• Trailer Stability Assist
WARNING •
The Electronic Stability Control system
ESC is supplementary driver support
intended to facilitate driving and make it
safer – it cannot handle all situations in
all traffic, weather and road conditions.
• ESC is not a substitute for the driver's
attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.
Stability control 3This function helps control the driving and brak-
ing force of each individual wheel in an attempt
to stabilize the vehicle.
Spin control and active yaw controlThis function is active at low speeds and brakes
the wheels that are spinning to transfer additional
power from wheels that are not spinning.
This function also helps prevent the wheels from
spinning while the vehicle is accelerating.
Engine drag control
Engine drag control (EDC
4
) helps prevent inad-
vertent wheel lock, e.g. after downshifting or
using engine braking when driving at low speeds
on a slippery surface.
Inadvertent wheel lock while driving could impair
the driver's ability to steer the vehicle.
Trailer Stability Assist* 5
Trailer Stability Assist (TSA
6
) is designed to help
stabilize a vehicle that is towing a trailer if the
vehicle and trailer have begun to sway. For more
information, see "Trailer Stability Assist".
NOTE The TSA function is deactivated if
ESC Sport
Mode is activated.
