Electronic Stability Control (ESC)
Electronic Stability Control (ESC) helps reducewheel spin, counteract skidding and to generallyhelp improve directional stability.
A pulsating sound will be audi-ble when the system is activelyoperating and is normal. Accel-eration may also be slightlyslower than normal.

WARNING
ESC is a supplementary aid and cannot dealwith all situations or road conditions.
The driver is always responsible for operatingthe vehicle in a safe manner in accordancewith current traffic regulations.
ESC consists of the following functions:
•Traction control
•Spin control
•Active Yaw Control
•Engine Drag Control
•Trailer Stability Assist

Traction control
This function is designed to help reduce wheelspin by transferring power from a drive wheel that
begins to lose traction to the wheel on the oppo-site side of the vehicle (on the same axle).
Spin control
This function is designed to help prevent thedrive wheels from spinning while the vehicle isaccelerating.

Active Yaw Control
At low speeds, this function helps maintain direc-tional stability by braking one or more of thewheels if the vehicle shows a tendency to skid orslide laterally.

Engine Drag Control EDC
EDC helps keep the engine running if the wheelsshow a tendency to lock, e.g., when shifting downin the manual shifting mode or while using theengine's braking function on a slippery surface. Ifthe wheels were to lock, the vehicle wouldbecome more difficult to steer.

Trailer Stability Assist * 1
TSA helps stabilize a vehicle that is towing atrailer when the vehicle and trailer have begun tosway.
This system is automatically deactivated if thedriver selects Sport mode.

Electronic Stability Control (ESC)sport mode
ESC is always activated and cannot be switchedoff.
However, the driver can select Sport mode,which offers more active driving characteristics.
In Sport mode, the engine management systemmonitors movement of the accelerator pedal andsteering wheel for sportier driving and allowsmore lateral movement of the rear wheels beforeESC is triggered.
Under certain circumstances, such as when driv-ing with snow chains, or driving in deep snow orloose sand, it may be advisable to temporarily useSport mode for maximum tractive force.
If the driver releases pressure on the acceleratorpedal, ETC will also activate to help stabilize thevehicle.

Activating/deactivating Sport mode
In the center display's Functionview, tap ESC Sport Mode.The green indicator light in thebutton will illuminate to showthat the function has been acti-vated or gray when the functionis deactivated.
When Sport mode is activated, thissymbol will illuminate in the instrumentpanel. It will remain on until the driverdeactivates the function. ETC will alsoreturn to normal mode when the engine is restar-ted.

SymbolMessageDescription
ESC Temporarily offThe ESC system function has been temporarily reduced due to high brake disc temperature. The function reac-tivates automatically when the brakes have cooled.
ESC Service requiredThe ESC system is not functioning properly.
•Stop the vehicle in a safe place, turn off the engine and restart it.
•If the message is still displayed when the engine has restarted, drive to an authorized Volvo workshop tohave the system inspected.

WARNING
The stability system is intended to helpimprove driving safety. It supplements, but cannever replace, the driver's judgment andresponsibility when operating the vehicle.Speed and driving style should always beadapted to traffic and road conditions.

Cruise Control (CC)
Cruise Control (CC) is designed to assist thedriver by maintaining a set speed. It is primarilyintended for use on long straight roads in steadytraffic, such as on highways and other mainroads in smoothly flowing traffic.

In models equipped with the optional AdaptiveCruise Control (ACC), the driver can togglebetween CC and ACC – see the article "Switch-ing between Cruise Control and Adaptive CruiseControl".

WARNING
•The vehicle must always be drivenaccording to current traffic/road condi-tions. The driver must take action if CCdoes not maintain a suitable speedand/or distance to other vehicles.
•The driver is always responsible for oper-ating the vehicle in a safe manner.

Distance Alert*
Distance Alert is a function that alerts the driverif the time interval to the vehicle ahead is tooshort.
Distance Alert is active at speeds above approxi-mately 20 mph (30 km/h) and only reacts to avehicle ahead that is driving in the same direc-tion. No information is provided for vehicles driv-ing toward you, moving very slowly, or at a stand-still.
Warning light (generic illustration)
A warning light in the windshield glows steadily ifyour vehicle is closer to the one ahead than theset time interval.

NOTE
Strong sunlight, reflections, extreme light con-trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

NOTE
Distance Alert only monitors distance to thevehicle ahead while Adaptive Cruise Control isin standby mode or off.

WARNING
Distance Alert only indicates the distance tothe vehicle ahead. It does not affect thespeed of your vehicle.
Head-up-display *
Distance Alert symbol in the windshield (generic illustra-tion)
In vehicle is equipped with the head-up display*,the symbol in the windshield will only appear ifthe distance to the vehicle ahead is shorter thanthe preset value. However, the Show DriverSupport In Head-Up Display function has tobe activated in the Settings menu. See the article"Head-up display" for additional information.

NOTE
Strong sunlight, reflections, extreme light con-trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

Distance Alert* limitations
Distance Alert uses the same radar sensor asAdaptive Cruise Control* and has several limita-tions.

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.
WARNING
•Poor weather or winding roads can affectthe radar sensor's capacity to detect vehi-cles ahead.
•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 shorterdistance than the one that has been setor not illuminating at all.
•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.
For additional information, see also the article"Radar sensor limitations."

Adaptive Cruise Control (ACC)*
ACC is an optional system designed to assistthe driver by maintaining a set speed or a settime interval to the vehicle ahead.
ACC helps provide more relaxed driving on longtrips on highways or other major roads in a rela-tively even flow of traffic.
The camera and radar sensor monitor the distance tothe vehicle ahead (generic illustration - certain detailsmay vary from model to model)
The driver sets that desired speed and time inter-val to the vehicle ahead. When the camera andradar sensor detects a slower moving vehicleahead, your vehicle's speed is automaticallyadapted. When there are no longer slower mov-ing vehicles ahead, your vehicle will accelerate toresume the set speed.
ACC is designed to follow a vehicle ahead in thesame lane and maintain a time interval to that
