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.
1Electronic Stability Control2Also called traction control.

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.

Putting Speed Limiter in standby mode
Note: This illustration is general and details may varydepending on model.
–Press ◀ (1) or ▶ (3) and scroll to the Speed
Limiter function (4).
> The symbol (4) will appear, indicating thatthe Speed Limiter is in standby mode.

Starting the Speed Limiter
The Speed Limiter can only be activated whilethe engine is running. The lowest maximumspeed that can be set is 30 km/h (20 mph).
–With the Speed Limiter in standby mode and
the symbol displayed, press the
button (2) on the steering wheel key-pad.
> The Speed Limiter will be started and thevehicle's current speed will be set as themaximum speed.

The Speed Limiter (SL11) can be temporarilydeactivated and put in standby mode.
Note: This illustration is general and details may varydepending on model.
To deactivate the Speed Limiter and put it instandby mode:
–Press the button on the steering wheel(2).
> The speed limit markings and symbols inthe instrument panel will change fromWHITE to GRAY. This indicates that theSpeed Limiter is temporarily deactivatedand the driver can exceed the set maxi-mum speed.
Temporarily deactivating using the
accelerator pedal
The set maximum speed can be temporarilydeactivated and exceeded using the acceleratorpedal without first putting the Speed Limiter instandby mode, e.g. when quick acceleration isrequired.
To do so:
1. Depress the accelerator as far as possibleand then release it when the desired speedhas been reached.
> The Speed Limiter will remain activatedand the symbol in the instrument panelwill be WHITE.
2. Release the accelerator pedal fully when thetemporary acceleration is completed.
> The vehicle will use engine braking toautomatically slow down to a speed belowthe most recently set 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.

NOTE
The greater the vehicles' speed, thegreater the distance between them for aset time interval.
Only use the time intervals permitted bylocal traffic regulations.
The set time interval is also used by theAdaptive Cruise Control and Pilot Assistfunctions.

WARNING
Only use a time interval suitable for thecurrent traffic conditions.
The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.

Distance Alert limitations32
Distance Alert functionality may be reduced incertain situations.
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

High speeds may also result in the warn-ing light illuminating at a shorter distancethan the one that has been set due tolimitations in the radar sensor's range.

NOTE
The function uses the vehicle's radar unit,which has some general limitations – see thesection "Radar unit limitations".

Adaptive Cruise Control*
Adaptive Cruise Control (ACC33) helps thedriver maintain a constant speed with a set timeinterval to the vehicle ahead.
Adaptive Cruise Control helps provide a morerelaxed driving experience on long trips on high-ways or long, straight roads with even trafficflows.
The camera/radar sensor measures the distance to thevehicle ahead34.
The driver sets a speed and a time interval to thevehicle ahead. If the camera/radar sensor detectsa slower-moving vehicle ahead, your vehicle'sspeed will be automatically adapted according tothe set time interval to that vehicle. When there
are no longer slower-moving vehicles ahead, thevehicle will return to the set speed.
WARNING
The Adaptive Cruise Control function issupplementary driver support intended tofacilitate driving and help make it safer –it cannot handle all situations in all traffic,weather and road conditions.
The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion (see the link list at the end of thisarticle).
Adaptive Cruise Control is not a substi-tute for the driver's attention and judg-ment. The driver is always responsible forensuring the vehicle is driven in a safemanner, at the appropriate speed, with anappropriate distance to other vehicles,and in accordance with current trafficrules and regulations.

NOTE
Depending on market, this function may beeither Standard or Optional.
