Function buttons and symbols
–Press the button (2).
> The set speed marker (4) and symbols will change colors from WHITE to GRAY. This indicates that CC is temporarily in standby mode and will not maintain a setspeed.
Standby mode due to action by the driverCC is temporarily deactivated and put in standby mode if:
• the brakes are applied
• The gear selector is moved to
N
• the vehicle is driven faster than the set speed for more than 1 minute.
In these cases, the driver will have to regulate the vehicle's speed. A temporary increase in speed, such as when passing another vehicle, does not affect the CCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released.
Automatic standby modeCC switches automatically to standby mode if:
• the wheels lose traction
• engine speed (rpm) is too high/low
• brake temperature is too high
• the vehicle's speed goes below approx. 20 mph (30 km/h)
In these cases, the driver will have to regulate the vehicle's speed.

Warning light
Adaptive Cruise Control can exert brake force that is equivalent to approximately 40% of thevehicle's total braking capacity. In situations requiring more brake force than ACC can provide and if the driver does not applythe brakes, an audible signal from the City Safetysystem will sound and warning light will illuminatein the windshield to alert the driver to react.
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.

Setting an Adaptive Cruise Control time interval
ACC makes it possible to set various time inter- vals to the vehicle ahead.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The greater the number ofbars, the longer the time inter-val. One bar between the vehi-
cles represents a time interval of approximately1 second; 5 bars is approximately 3 seconds. The same symbol appears if Distance Alert is activated.
• If the symbol shows two vehicle's, ACC is actively following the vehicle ahead.
• If only one vehicle is displayed, ACC is
not
actively following another vehicle.

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.

Starting and activating Pilot Assist
The Pilot Assist feature helps keep the vehicle in its current traffic lane, at a set speed and a settime interval to the vehicle ahead.
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.
A YELLOW symbol with a flashing WHITE arrowindicates that the system is about to shift intostandby mode.
With ACC in standby mode: 1. Tap ▶ (4).
> The symbol will be displayed and Pilot Assist will go into standby mode.
2. Press the
button (1) on the left-side
steering wheel keypad.
> Pilot Assist will go into active mode.
WARNING
• Pilot Assist is not a collision avoidance system. The driver is always responsiblefor applying the brakes if the system doesnot detect another vehicle.
• 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 heavy

rain or snow, in poor visibility, on winding roads or on highway on- or off-ramps.
• Pilot Assist uses the vehicle's cameraand radar sensor, which have limitations.
Pilot Assist may deactivate or not function optimally if:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• if there are edges or other lines on ornear the lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
• the weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations: • High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.• Pilot Assist does not "see" pedestrians, animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
Hands on the steering wheelPilot Assist only functions when the driver's hands are on the steering wheel
, which is con-
tinuously monitored by the system. If this is notthe case, the driver will be alerted by a text mes-sage in the instrument panel. If the driver's handsare not returned to the steering wheel, an audiblesignal will sound. If the driver does not return his/her hands to the steering wheel after the audible signal, PilotAssist will go into standby mode and must be reactivated by pressing
