cle's speed when the button is pressed will become the set speed assuming that the accel- erator pedal is still depressed when the button ispressed. 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. Alwaysobserve posted speed limits.
Engine braking instead of applying the
brakes
CC regulates speed by applying the brakeslightly. To avoid a loss of speed when drivingdown hills, use the engine braking functioninstead of letting the CC apply the brakes. In thissituation, the driver can temporarily deactivate theCC braking function. To do so:
–Press the accelerator pedal approx. halfway down and release it.
> CC will automatically deactivate the auto- matic brake function and will then only use the engine braking function.

Distance Alert * limitations
Distance Alert uses the same radar sensor as Adaptive Cruise Control * and has several limita-
tions.
WARNING
• The radar sensor has a limited field of vision. 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
At speeds above 20 mph (30 km/h), if ACC
changes targets from a moving vehicle to a stationary one, 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 determineif the 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.
Deactivation of the auto-hold brake function
In certain situations, auto-hold will be deactivated when the vehicle is at a standstill and ACC will gointo standby mode. This means that the brakes will be released and the vehicle can begin to roll. The driver must actively apply the brakes to keep the vehicle at a standstill. This can occur in the following situations: • the driver presses the brake pedal
• the parking brake is set •
the gear selector is moved to the
P, N or R
positions
• the driver puts ACC in standby mode.
Automatically setting the parking brakeIn certain situations, the parking brake is set automatically to help keep the vehicle at a stand-still. This occurs if ACC keeps the vehicle at a stand- still with the brakes and:
• the driver unbuckles the seat belt or opensthe door
• ACC has kept the vehicle at a standstill formore than approx. 5 minutes
• the brakes overheat
• the engine is turned off.

Prerequisites
The prerequisites for activating Pilot Assist are:• The driver's seat belt must be buckled and the driver's door must be closed.
• There must be a vehicle ahead (a target vehi-cle) within a reasonable distance or yourvehicle's current speed must be at least9 mph (15 km/h).
With ACC in standby mode: 1. Tap
▶ (6).
> The symbol
will change to Pilot
Assist in standby mode (8).
2. Press the
button (2) on the left-side
steering wheel keypad.
> Pilot Assist will go into active mode and the current speed will be stored and dis- played in the center of the speedometer. or
If Adaptive Cruise Control has been started:
–Tap ▶ (6).
> Pilot Assist will start.
Pilot Assist's steering assis- tance is only active when thesteering wheel symbol (2)changes from GRAY toGREEN.
And Pilot Assist will only regulate the time inter- val to the vehicle ahead when a vehicle symbol(1) is displayed above the steering wheel. At the same time, a speedinterval will be marked. The higher speed is the one stored by the driver and thelower one is the speed of thevehicle ahead (target vehicle).WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle. Do not use Pilot Assist in demanding driving conditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps. In certain situations, it may be difficult for Pilot Assist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
• 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.
• there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
