Stability system – operation
Operation
Sport modeThe stability system is always activated and cannot be switched off.
However, the driver canselect Sport mode, which
offers more active drivingcharacteristics. Sport mode can be selected
in the MY CAR menus, see
My Car – introduction (p. 76).
In Sport mode, the engine management sys-
tem monitors movement of the accelerator pedal and steering wheel for sportier drivingby allowing more lateral movement of the rearwheels before ESC is activated. Under certain circumstances, such as when driving with snow chains, or driving in deepsnow or loose sand, it may be advisable totemporarily use Sport mode for maximum
tractive force. If the driver releases pressure on the acceler- ator pedal, ETC will also activate to help sta-bilize the vehicle. To switch to Sport mode:
Sport mode remains active until the driver
switches it off in the menu or until the engine is switched off. ETC will return to normal mode when the engine is restarted.

Road Sign Information (RSI) – limitations
RSI's camera has the same limitations as the human eye. See The camera’s limitations(p. 217) for more information about the cam-era's limitations. Signs that indirectly indicate the speed limit (such as a sign with a town's name and thepermitted speed limit) will not be registeredby RSI. Other factors that may interfere with RSI include:
• Faded signs
• Signs located in a curve
• Twisted or damaged signs
• Obstructed signs
• Signs that are partially covered by snow, ice, etc.

Adaptive Cruise Control – passing another vehicle
Passing another vehicleIf your vehicle’s speed is being regulated by ACC and the driver indicates that he/shewould like to pass the vehicle ahead by usingthe left turn signal, ACC can assist by accel-
erating briefly. This function is active at speeds above approximately 45 mph (70 km/h).
WARNING
Please be aware that this function will also cause the vehicle to accelerate briefly incertain situations other than passinganother vehicle, for example using the leftturn signal to indicate a lane change or aturn toward a highway exit at speedsabove approximately 45 mph (70 km/h).

Adaptive Cruise Control (ACC) – Queue Assist
Queue Assist is an added ACC feature that is linked to your vehicle's automatic transmis-sion.
IntroductionQueue Assist is an added ACC feature that islinked to your vehicle's automatic transmis-sion. Queue Assist consists of the following func- tions: •Enhanced speed interval (including when the vehicle is at a complete stop or ismoving at speed below 18 mph(30 km/h))
• Automatic standby mode when ACCchanges target vehicles
• No automatic braking when at a standstill
• The parking brake is applied automati-cally
Please note that the lowest speed that can be set is 18 mph (30 km/h), although ACC canmaintain a set speed/distance to a vehicleahead down to a standstill. Queue Assistconsists of the following features:
Enhanced speed interval
NOTE
The driver's door must be closed and the driver's seat belt must be fastened beforeACC can be put in active mode. If the driv-er's seat belt is taken off or if the driver'sdoor is opened, ACC will return to standbymode.
Your vehicle can maintain the set time interval to the vehicle ahead at any permissiblespeed, including a complete stop. In order to activate ACC at speeds below 18 mph (30 km/h):
• The vehicle ahead must be within a rea- sonable distance (not farther away thanapprox. 100 ft/30 meters)
• The lowest speed that can be selected is18 mph (30 km/h), although ACC will alsohelp maintain the set time interval to thevehicle ahead at lower speeds, includinga complete stop.
During short stops (less than approximately 3 seconds) in slow-moving traffic, your vehi-cle will begin moving again automatically assoon as the vehicle ahead begins to move. If it takes more than 3 seconds for the vehicle ahead to begin moving, ACC will be automat-ically go into standby mode.

Collision warning – introduction
Pedestrian and Cyclist Detection with Full Auto Brake is designed to assist the driver ifthere is a risk of a collision with a pedestrian,a cyclist, a vehicle ahead that is at a standstillor one that is moving in the same direction asyour vehicle. This system consists of the following three functions: • Collision Warning
warns the driver of a
potential collision situation.
• Brake Support
helps the driver brake
efficiently in a critical situation.
• Auto-brake
brakes the vehicle automati-
cally if a collision with a pedestrian, a cyclist or another vehicle cannot be avoi-ded and the driver does not apply thebrakes in time or steer around the per-son/vehicle. Auto-brake can help preventa collision or reduce the speed at which acollision occurs.
Since Pedestrian and Cyclist Detection with Full Auto Brake is activated in circumstanceswhere the driver should have begun brakingmuch sooner, the system will not be able toassist the driver in all situations. This system is designed to activate as late as possible to help avoid unnecessary interven-tion. The system should not be used in such a way that the driver changes his/her way of operat- ing the vehicle. If the driver relies entirely onthe system, the chances of an accident even-tually occurring increase considerably. The Pedestrian and Cyclist Detection with Full Auto Brake and City Safety™ systems sup-plement each other. See City Safety – intro-duction (p. 202) for detailed information aboutCity Safety™.
WARNING
No automatic system can be guaranteed to function 100% correctly in all situations.For that reason, never test the Auto-brakesystem by driving toward a person orobject. This could result in serious injury ordeath.

Audible signalThe Park Assist system uses an intermittent tone that pulses faster as you come close toan object, and becomes constant when youare within approximately 1 ft (30 cm) of anobject in front of or behind the vehicle. Ifthere are objects within this distance bothbehind and in front of the vehicle, the tonealternates between front and rear speakers.
NOTE
The level of the audible signal can be low- ered/raised with the infotainment volumecontrol. The level can also be set in the MYCAR menu system. See My Car – introduc-tion (p. 76) for a description of the menusystem.
If the volume of another source from the audio system is high, this will be automati-cally lowered.
Rear park assist
G017833
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The audible signalcomes from the rear speakers. The system must be deactivated when towing a trailer, carrying bicycles in a rear-mountedcarrier, etc, which could trigger the rear parkassist system's sensors.
NOTE
•Rear park assist is deactivated auto- matically when towing a trailer if Volvogenuine trailer wiring is used. If a non-Volvo trailer hitch is being used, it maybe necessary to switch off the systemmanually, see Park assist – operation(p. 234).
• The system will not detect highobjects, such as a loading dock, etc.
• Objects such as chains, thin shinypoles or low objects may temporarilynot be detected by the system. Thismay result in the pulsing tone unex-pectedly stopping instead of changingto a constant tone as the vehicleapproaches the object. In such cases,use caution when backing up or stopthe vehicle to help avoid damage.

BLIS* – function
When does BLIS functionThe system functions when your vehicle is moving at speeds above 6 mph (10 km/h).
When you pass another vehicle:The system reacts when you pass another vehicle at a speed of up to 6 mph (10 km/h)faster than that vehicle.
When you are passed by another
vehicle:
The system reacts if your vehicle is passed by another vehicle at a speed of up to 43 mph(70 km/h) faster than your vehicle.
WARNING
• BLIS does not function in sharp curves.
• BLIS does not function when yourvehicle is backing up.
• If you are towing a wide trailer, thismay prevent the BLIS cameras fromdetecting other vehicles in adjacentlanes.
How BLIS functions in daylight and darkness
DaylightBLIS reacts to the
shape of surrounding vehi-
cles. The system is designed to help detect motor vehicles such as cars, trucks, buses, motorcycles, etc.
DarknessBLIS reacts to the
headlights of surrounding
vehicles. In order to be detected by BLIS, a vehicle in the blind area must have its head-lights on. This means, for example, that thesystem will not detect a trailer without head-lights that is being towed behind a car ortruck.
WARNING
• BLIS does not react to cyclists or mopeds.
• BLIS does not react to vehicles thatare standing still.
• The BLIS cameras have the same limi-tation as the human eye. In otherwords, their "vision is impaired" byadverse weather conditions such asheavy snowfall, intense light directlyinto the camera, dense fog, etc.
