Electronic Stability Control
The Electronic Stability Control (ESC1) functionhelps the driver avoid skidding and improves thevehicle's directional stability.
This symbol will be displayed inthe instrument panel when theESC system is intervening.
When the ESC has intervenedto apply the brakes, a pulsingsound may be heard and thevehicle may accelerate more slowly than expec-ted when the accelerator pedal is depressed.
The ESC system consists of the following sub-functions:
Stability control2
Spin control and active yaw control
Engine drag control
WARNING
The Electronic Stability Control systemESC 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 2
This function helps control the driving and brak-ing force of each individual wheel in an attemptto stabilize the vehicle.

Spin control and active yaw control
This 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 fromspinning while the vehicle is accelerating.

Speed limiter
A Speed Limiter (SL7) could be described as areverse cruise control. The driver regulates thevehicle's speed using the accelerator pedal, butis prevented by the Speed Limiter from inadver-tently exceeding a preset maximum speed.

WARNING
The ASL function is supplementary driversupport intended to facilitate driving andhelp make it safer – it cannot handle allsituations in all traffic, weather and roadconditions.
Even if the driver can clearly see thespeed limit sign, the speed informationfrom the Road Sign Information (RSI)function to ASL may be incorrect. In suchcases, the driver must intervene andaccelerate or brake to an appropriatespeed.
ASL 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.
See also the heading "Road Sign Infor-mation limitations".
Is SL or ASL active?
The symbols in the instrument panel indicatewhich Speed Limiter function is active:

Activating/deactivating AutomaticSpeed Limiter
The Automatic Speed Limiter (ASL) is a supple-ment to the Speed Limiter (SL) and can be acti-vated/deactivated.

Activating ASL
The Speed Sign Assist but-ton is located in the center dis-play's Function view.
To activate the Automatic Speed Limiter:
1.Tap the Speed Sign Assist button.
> ASL will go into standby mode and agreen indicator light will illuminate. A roadsign symbol will be displayed in the centerof the speedometer in the instrumentpanel.
2.Pressing the button on the steeringwheel keypad.
> ASL will be activated and set to the vehi-cle's current speed.
NOTE
If the Automatic Speed Limiter function isactivated, road sign information is shown
in the driver display even if RSI15 is notactivated.
To remove road sign information from thedriver display, you must deactivate bothAutomatic Speed Limiter and RSI.
When the Automatic Speed Limiter func-tion is activated but RSI is deactivated, nowarnings are given from RSI. RSI mustalso be activated for warnings to be pos-sible.

Deactivating ASL
To deactivate the Automatic Speed Limiter:
–Tap the Speed Sign Assist button in Func-tion view.
> ASL will be deactivated, the indicator lightin the button will be GRAY and SL will beactivated instead.

WARNING
The vehicle will no longer follow the postedmaximum speed after switching from ASL toSL – it then only follows the maximum speedstored in the memory.

Standby mode due to action by the driver
Cruise Control will be temporarily deactivated andput in standby mode if:
the brakes are applied
the gear selector is moved to N
the vehicle is driven faster than the setspeed for more than 1 minute
The driver must then control the vehicle's speed.
Temporarily increasing speed using the accelera-tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.

Automatic standby mode
Cruise Control will be temporarily deactivated andput in standby mode if:
the wheels lose traction
the engine speed (rpm) is too low/high
the temperature in the brake systembecomes too high
the vehicle's speed goes below 30 km/h(20 mph).
The driver must then control the vehicle's speed.

WARNING
The radar sensor has a limited field ofvision. In some situations, it may detect avehicle later than expected or not detectother vehicles at all.
The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see. Poorweather or winding roads can affect theradar sensor's capacity to detect vehiclesahead.
A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorter
