If the radar sensor doesnot detect a vehicle ahead, it will insteadmaintain the speed set by the driver. Thiswill also happen if the speed of the vehicleahead exceeds the set speed for your vehi-cle.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.
CAUTION
Only a workshop may perform mainte- nance on driver support components – anauthorized Volvo workshop is recom-mended.

standby
mode
Adaptive Cruise Control (ACC 44
) can be deac-
tivated and put in standby mode. This may happen automatically or be due to driverintervention.
Standby mode means that the function is selected in the instrument panel but not acti-vated. In standby mode, Adaptive Cruise Con-trol will not regulate speed or distance to thevehicle ahead.
Standby mode due to action by the
driver
Adaptive Cruise Control will be deactivatedand put in standby mode if any of the follow-ing occurs:
The brakes are applied.
The gear selector is moved to
N.
The vehicle is driven faster than the setspeed for more than 1 minute.
Temporarily increasing speed using the accel-erator pedal, e.g. when passing another vehi-cle, will not affect the setting. The vehicle willreturn to the set speed when the acceleratorpedal is released.
WARNING
If Adaptive Cruise Control is in standby mode, the driver must intervene andregulate both speed and distance tothe vehicle ahead.
If the vehicle comes too close to a vehi-cle ahead when Adaptive Cruise Con-trol is in standby mode, the driver canbe warned of the short distance by the Distance Alert

limited functionality in certain situations.
Steep roads and/or heavy loadsAdaptive Cruise Control is primarily intended to be driven on flat roads. The function maynot be able to maintain the correct time inter-val to the vehicle ahead when driving downsteep hills. The driver should be extra attentiveand prepared to apply the brakes. Do not use Adaptive Cruise Control if the vehi- cle is carrying a heavy load or towing a trailer.
Drive mode unavailableThe Off Road drive mode cannot be selected
if Adaptive Cruise Control is activated.
WARNING
This is not a collision avoidance sys- tem. The driver is always responsibleand must intervene if the system failsto detect a vehicle ahead.
The function does not brake for peopleor animals and does not brake for smallvehicles, such as bikes and motorcy-cles. Similarly, it does not brake for lowtrailers, oncoming, slow-moving or sta-tionary vehicles and objects.
Do not use the function in demandingsituations, such as in city traffic, atintersections, on slippery surfaces,with a lot of water or slush on the road,in heavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Pilot Assist can help the driver keep the vehi- cle in the current traffic lane and maintain aneven speed and a set time interval to thevehicle ahead.
Get to know Pilot Assist
The camera/radar sensor monitors the distance to the vehicle ahead and detects lane markings.
Camera and radar sensor

Pilot Assist helps to steer the vehicle, and you may need to drive a few miles with Pilot Assistbefore you feel completely at home with the function. It is important to be familiar with all of the function's applications and limitations in order to take advantage of all it has to offer. The Pilot Assist function is primarily intended for use on highways and other major roadswhere it can help provide a more comfortableand relaxing driving experience. The driver sets the desired speed and distance to the vehicle ahead. Pilot Assist monitors thedistance to the vehicle ahead and the trafficlane's side markers using the camera. The sys-tem maintains the set time interval to the vehi-cle ahead by automatically adjusting your vehi-cle's speed and keeps your vehicle in its laneby providing steering assistance. If the Curve Speed Assist (CSA)
* function is
activated, it may also affect the vehicle's speed. Pilot Assist regulates speed by accelerating and braking. It is normal for the brakes to emita slight sound when they are being used toadjust speed. Pilot Assist is designed to:
smoothly regulate speed. The driver must apply the brakes in situations requiringimmediate braking. For example, whenthere are great differences in speedbetween vehicles or if the vehicle aheadbrakes suddenly. Due to limitations in the camera and radar sensor, braking mayoccur unexpectedly or not at all.

If the radar sensor doesnot detect a vehicle ahead, it will insteadmaintain the speed set by the driver. Thiswill also happen if the speed of the vehicleahead exceeds the set speed for your vehi-cle.
The vehicle's position in the traffic
lane
When Pilot Assist helps to steer, it attempts toposition the vehicle halfway between the visi-ble lane marking lines. For a smoother drive, itis a good idea to allow the vehicle to find agood position. The driver can always adjustthe position him/herself by increasing steeringinput. It is important for the driver to makesure the vehicle is positioned safely in the lane. If Pilot Assist does not position the vehicle appropriately in the lane, the driver should turnoff Pilot Assist or switch to Adaptive Cruise Control *.

WARNING
The driver should be aware that if condi- tions suddenly change when using PassingAssistance, the function may implement anundesired acceleration in certain condi-tions. Some situations should be avoided, e.g. if: the vehicle is approaching an exit in the same direction as passing would nor-mally occur
the vehicle ahead slows before yourvehicle has had time to switch to thepassing lane
traffic in the passing lane slows down
Situations of this type can be avoided by temporarily putting Adaptive Cruise Controlor Pilot Assist in standby mode.

Collision risk warning from driver support
The driver support systems Adaptive Cruise Control * and Pilot Assist * can help alert the
driver if the distance to the vehicle ahead suddenly decreases to an unsafe distance.
Collision warning audible signal and symbol
Audible signal at risk of collision
Collision warning symbol
Camera/radar sensor distance monitoring
Adaptive Cruise Control and Pilot Assist use approx. 40% of the braking capacity. If a sit-uation requires more braking force than driversupport can provide, and if the driver does not apply the brakes, a warning light and audible warning signal will be activated to alert thedriver that immediate action is required.
WARNING
The driver support system only issues a warning for vehicles detected by its radarunit – thus, a warning may come after adelay or not at all. Never wait for a warning.Apply the brakes when necessary.
Collision warning symbol on the windshield
In vehicles equipped with a head-up display *,
a flashing warning symbol will be displayed on the windshield.
NOTE
Visual warnings on the windshield may be difficult to notice in cases of strong sun-light, reflections, extreme light contrasts,or if the driver is wearing sunglasses or isnot looking straight ahead.

Switching target vehicles with driver support
At certain speeds, vehicles with automatic transmissions and the driver support func- tions Adaptive Cruise Control * and Pilot
Assist * can switch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When driver support is actively following another vehicle at speeds under 30 km/h
(20 mph) and switches targets from a movingvehicle to a stationary vehicle, driver supportwill brake for the stationary vehicle.
WARNING
When driver support follows another vehi- cle at speeds over approx. 30 km/h
(20 mph) and changes target vehicle –from a moving vehicle to a stationary one –driver support will ignore the stationary
vehicle and instead accelerate to the storedspeed. The driver must then intervene and apply the brakes.
Automatic standby mode when switching targets
Driver support disengages and goes into standby mode if:
your vehicle's speed goes under 5 km/h(3 mph) and driver support cannot deter-mine if the target vehicle is stationary or ifit is another object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns sothat driver support no longer has a vehicleto follow.
