* 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

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
See Owner's manual is displayed in
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.
