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

Speed-dependent steering wheelresistance
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 tomove 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 willwork at reduced output and the steeringwheel may feel more difficult to move. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage as well as a STEERING WHEELsymbol.

DRIVER SUPPORT
* Option/accessory.263
WARNING
While the power steering is working at reduced power, the driver support functionswith 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 optionunder "Available drive modes" in the "Drivemodes" section. On models not equipped with drive mode con- trols and the INDIVIDUAL option, steering wheelresistance can instead be set in the center dis-play's Top view under:

Stability system Roll StabilityControl
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 vehiclebegins to skid.
The RSC system monitors the lateral angle at which the vehicle is leaning and registers anychanges. Using this information, the system cal-culates the likelihood of a rollover. If there is animminent risk of a rollover, Electronic StabilityControl is activated, engine torque is reduced andbrakes are applied to one or more of the wheelsuntil the vehicle has regained stability.

Electronic Stability ControlThe 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 theESC system is intervening. When the ESC has intervened to apply the brakes, a pulsingsound 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
WARNING
• The Electronic Stability Control system ESC is supplementary driver supportintended to facilitate driving and make itsafer – it cannot handle all situations inall traffic, weather and road conditions.
• ESC is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance 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 attemptto stabilize the vehicle.
Spin control and active yaw controlThis function is active at low speeds and brakesthe wheels that are spinning to transfer additionalpower 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 orusing engine braking when driving at low speedson a slippery surface. Inadvertent wheel lock while driving could impair the driver's ability to steer the vehicle.

Electronic Stability Control Sportmode
The ESC 5
system is always activated and can-
not be switched off. However, the driver can select
ESC Sport Mode, which offers more
active driving characteristics.
With the ESC Sport Mode sub-function
selected, intervention from ESC is reduced and more lateral movement is permitted, giving thedriver more control of the vehicle than usual. When
ESC Sport Mode is selected, ESC may
seem to be disabled even though it is often assisting the driver.
ESC Sport Mode also helps provide maximum
traction if the vehicle gets stuck or is driving on a loose surface such as deep snow or loose sand.

Sport mode can be activated/ deactivated in the center dis-play's Function view.
–Tap the ESC Sport Mode button in Func-
tion view.
> Sport mode is activated when the indica- tor light is green, and deactivated when the indicator light is gray.
When
ESC Sport Mode is activated,
this symbol will illuminate with a steady glow in the instrument panel. It willremain on until the driver deactivates
the function or until the engine is turned off. TheESC system will return to normal mode the nexttime the engine is started.

Electronic Stability Control symbolsand messages
A number of symbols and messages related to Electronic Stability Control (ESC) may be dis-played in the instrument panel.
Some examples of symbols and messages are shown in the table below.
SymbolMessageMeaning
Steady glow for approx. 2 seconds. System check when the engine is started.
Flashing light. The ESC is actively operating.
Steady glow. Sport mode is activated.
Note: The ESC system is not deactivated in this mode, but has partially reduced functionality.
ESC Temporarily offThe ESC system's functionality has been temporarily reduced due to high brake system temperatures. The function will be automatically reactivated when the brakes have cooled. See the message in the instrument panel.
ESC Service requiredThe ESC system is not functioning properly.
• Stop the vehicle in a safe place, turn off the engine and then restart it.
• Consult a workshop if the message persists
‒ an authorized Volvo workshop is recommended.
A text message can be erased by briefly pressing the
button in the center of the right-side
steering wheel keypad. If the message persists: Contact a workshop
‒ an
authorized Volvo workshop is recommended.
