WARNING
•Pilot Assist is designed to be a supple- mentary driving aid and cannot cover alldriving situations, traffic, weather and/orroad conditions.
• The driver should be familiar with all ofthe information in this article regardingPilot Assist, including its limitations.
• Pilot Assist is not intended to replace thedriver's attention and judgement.
• Pilot Assist must only be used wherethere are clearly visible traffic lane sidemarker lines on both sides of the currenttraffic lane. In other circumstances thereis an increased risk of collision with sur-rounding obstacles that are not detectedby the system.
• The driver is always responsible for steer-ing the vehicle and maintaining a suitablespeed and distance to the vehicle aheadand must intervene if necessary, even ifPilot Assist is being used.
Pilot Assist is designed to regulate speed smoothly but in situations calling for fast braking,the driver must apply the brakes. This applies tosituations where there are considerable differen-ces in speed or if the vehicle ahead brakes sud-denly. Due to the limitations of the camera andradar sensor, the system may apply the brakes inyour vehicle suddenly or not at all. The default speed for Pilot Assist is preset toapprox. 30 mph (50 km/h) and cannot bechanged. If the vehicle ahead increases speed toover 30 mph (50 km/h) and pulls away from yourvehicle, Pilot Assist will go into standby mode.
NOTE
•
Pilot Assist maintenance should only be carried out by a trained and qualifiedVolvo service technician.
• Pilot Assist regulates your vehicle'sspeed using the accelerator pedal andthe brakes. Please be aware that theremay be a faint sound from the brakeswhen the system is using them.
WARNING
•Pilot Assist does not react to people or animals, or small vehicles such as bicy-cles and motorcycles. It also does notreact to low trailers, slow moving, parkedor approaching vehicles, or stationaryobjects.
• Do not use Pilot Assist in demandingdriving conditions such as city driving orother heavy traffic situations, in slipperyconditions, when there is a great deal ofwater or slush on the road, during heavyrain or snow, in poor visibility, on windingroads or on highway on- or off-ramps.

Function buttons and symbols
PrerequisitesThe prerequisites for activating Pilot Assist are:
• The vehicle ahead must be within a reasona- ble (detectable) distance
• The camera must be able to clearly detectthe traffic lane's side marker lines
• The vehicle's speed must be under approx.30 mph (50 km/h). A WHITE symbol indicates that Pilot Assist has been selected. In other cases, the WHITE arrow pointing to the right indi-cates that the system is availa-ble.

Standby mode due to driver actionIf a turn signal is used or if the accelerator pedal is pressed, Pilot Assist will temporarily go intostandby mode. When the turn signal is switchedoff or the accelerator pedal is released, PilotAssist will reactivate automatically. Automatic reactivation from standby mode can be done within 1 minute. After 1 minute haselapsed, Pilot Assist must be reactivated man- ually by pressing the
button.
Pilot Assist will temporarily go into standby mode if: • the brakes are applied
• the gear selector is moved to the
N position.
The driver will then have to regulate speed and distance to the vehicle ahead, or reactivate Pilot Assist manually by pressing the
button on
the left-side steering wheel keypad.
Automatic standby modePilot Assist interacts with other systems, such as Electronic Stability Control. If any of these othersystems are not functioning properly, Pilot Assistwill automatically be deactivated.
WARNING
If this happens, the driver will be alerted by an audible signal and a message in the instru-ment panel. The driver will have to adapt thevehicle's speed, apply the brakes when nec-essary and keep a safe distance to the vehicleahead.
Pilot Assist switches automatically to standby mode if: • the camera cannot detect the traffic lane's side marker lines
• the vehicle ahead is not within a reasonable(detectable) distance
• the driver's hands are not on the steeringwheel
• the driver unbuckles the seat belt
• engine speed (rpm) is too high/low
• the wheels lose traction
• brake temperature is too high
• the stability system's
ESC Sport Mode is
activated
• drive mode
Off Road is selected
• The camera/radar sensor is covered by e.g., wet snow or if heavy rain interferes with radarwaves

Other Adaptive Cruise Control (ACC) functionsACC is an optional system designed to assist
the driver by maintaining a set speed or a set time interval to the vehicle ahead.
ACC has several supplementary functions:
• Changing target vehicles
• Automatic standby mode when changing tar- gets
• Auto-hold brake function
• Deactivation of the auto-hold brake function
• Automatically setting the parking brake
Changing target vehicles
If the target vehicle turns suddenly, there may be a sta- tionary vehicle ahead
When ACC is actively following another vehicle at speeds
under 20 mph (30 km/h) and changes
targets from a moving vehicle to a stationary one, the system will brake for the stationary vehicle.
WARNING
If ACC changes targets from a moving vehicle to a stationary one at speeds above 20 mph
(30 km/h), the system will not react to the
stationary vehicle and will accelerate to the previously set speed. The driver must actively apply the brakes to slow/stop the vehicle.
Automatic standby mode when changing targets
ACC disengages and goes into standby mode if:
• your vehicle's speed goes below approx. 3 mph (5 km/h) and ACC cannot determine ifthe target object is a stationary vehicle orsome other type of object such as a speedbump, etc
• the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that ACC nolonger has a target vehicle to follow
Auto-hold brake functionIn slow-moving, stop-and-go traffic or when stop- ped at a traffic light, driving will resume automati-cally if the vehicle is not stopped for more thanapprox. 3 seconds. If it takes more than3 seconds for the vehicle ahead to begin movingagain, ACC will go into standby mode and theauto-hold brake function will activate.
–The driver will then have to reactivate ACC in one of the following ways:
• Press the
button on the left-side
steering wheel keypad
• Press the accelerator pedal
> ACC will resume following the vehicle ahead (target vehicle) if it begins to move
within approx. 6 seconds.
NOTE
ACC can keep the vehicle at a standstill for up to 5 minutes, after which the parking brakewill be set and ACC will go into standbymode. The parking brake has to be released before ACC can be reactivated.
