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

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:

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.

WARNING•
The ASL function is supplementary driver
support intended to facilitate driving and
help make it safer – it cannot handle all
situations in all traffic, weather and road
conditions.
• Even if the driver can clearly see the
speed limit sign, the speed information
from the Road Sign Information (RSI)
function to ASL may be incorrect. In such
cases, the driver must intervene and
accelerate or brake to an appropriate
speed.
• ASL 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-

Changing Automatic Speed Limiter
tolerance
The Automatic Speed Limiter (ASL
23
) can be set
to different tolerance levels.
It is also possible to allow the vehicle to drive
above or below the posted speed limit. For exam-
ple, if the vehicle is following a current posted
speed limit of 70 km/h (43 mph), the driver can
instead allow the vehicle to maintain a speed of
75 km/h (47 mph). Function buttons and symbols

. –
Tap the (1) button on the steering
wheel keypad until 70 km/h (43 mph) has
been changed to 75 km/h (47 mph) in the
center of the speedometer (4).
>

The vehicle will then use the selected tol-
erance of 5 km/h (4 mph) as long as the
posted speed limit the vehicle passes is
70 km/h (43 mph).
This tolerance level will be followed until
the vehicle passes a sign with a lower or
higher speed. The vehicle will then adjust
to the new speed limit and the set toler-
ance will be deleted from the system's
memory.
If Road Sign Information* is activated, the
posted speed limit will then be indicated
by a RED marking on the speedometer's
speed scale.
The set tolerance can be adjusted in the same
way as for the Speed Limiter's speed.
NOTE The highest possible selectable tolerance is
+/- 10 km/h (5 mph).

Speed limiter (p. 278) Automatic Speed Limiter limitations
ASL utilizes the speed limit information provided
by the RSI 25
system, not from the speed limit
signs that the vehicle passes.
If RSI 25
is unable to interpret and provide ASL
with speed information, ASL will go into standby
mode and switch over to SL. The driver will then
have to actively brake to bring the vehicle down
to the appropriate speed.
ASL will be reactivated when RSI 25
is once again
able to interpret and provide speed information to
ASL.
See "Road Sign Information limitations" for more
information.

288Managing Cruise Control speed
Cruise Control (CC 29
) can be set to various
speeds.
Setting/changing set speed Note: This illustration is general and details may vary
depending on model.
For vehicles with only CC
–
Change a set speed by pressing the (1)
or (3) buttons briefly or by pressing and
holding them:
• Press briefly: Press briefly: each press
changes the speed in +/- 1 mph
(+/- 1 km/h) increments.
• Press and hold: Release the button when
the set speed indicator (4) has moved to
the desired speed. •
The most recently set speed will be stored.
If speed is increased by depressing the accelera-
tor pedal while pressing the (1) button on
the steering wheel, the vehicle's speed when the
button is pressed will be stored as the set speed.
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will
not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
For vehicles with both CC and ACC
– Change a set speed by pressing the (1)
or (3) buttons briefly or by pressing and
holding them:
• Press briefly: Press briefly: each press
changes the speed in +/- 5 mph
(+/- 5 km/h) increments.
• Press and hold: Release the button when
the set speed indicator (4) has moved to
the desired speed.
• The most recently set speed will be stored.
If speed is increased by depressing the accelera-
tor pedal while pressing the (1) button on
the steering wheel, the vehicle's speed when the
button is pressed will be stored as the set speed.
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applying
the brakes. On downgrades, it can sometimes be
desirable to roll a bit faster and let speed be
reduced instead by engine braking alone. The
driver can temporarily disengage the Cruise Con-
trol braking function.
To disengage CC:
– Press the accelerator pedal about halfway
down and then release it.
>

Cruise Control will automatically disen-
gage the automatic brake function and
speed will only be reduced using the
engine braking function.
How drive mode affects cruise controlThe way the cruise control maintains the vehicle's
speed can vary depending on the selected drive
