The radar sensor's capacity to detect vehicles ahead is impeded:
• if the speed of the vehicle ahead differs greatly from your vehicle's speed.
Limited field of visionThe radar sensor has a limited field of vision. In some situations it may detect a vehicle later thanexpected or not detect other vehicles at all.
Radar sensor's field of vision
In certain situations, the radar sensor cannot detect vehicles at close quarters, for examplea vehicle that suddenly enters the lanebetween your vehicle and the target vehicle.
Small vehicles, such as motorcycles, or vehi- cles not driving in the center of the lane mayremain undetected.
In curves, the radar sensor may detect the wrong vehicle or lose sight of the target vehi-cle.
Low trailer in the radar shadow
Low trailers may also be difficult to detect or may not be detected at all. The driver should be extraalert in situations of this type.
High temperaturesIf the temperature in the passenger compartmentis very high, the camera and radar sensor may betemporarily turned off for approx. 15 minutesafter the engine has been started to protect theirelectronic components. When the temperaturehas cooled sufficiently, the camera and radarsensor will restart automatically.

Changing Cruise Control speed
Changing a set speed
Function buttons and symbols
–Change a set speed by pressing the (1)
or — (2) buttons briefly or by pressing and
holding them:
• Press briefly
: changes speed in
+/– 1 mph (+/– 1 km/h) increments. Each press changes the vehicle's speedby +/– 1 mph (+/– 1 km/h).
• Press and hold
: Release the button
when the set speed indicator (4) hasmoved to the desired speed.
If speed is increased by pressing the accelerator pedal before the
button is pressed, the vehi-
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.
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.

To temporarily deactivate and put Cruise Control in standby mode:
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 driver
CC 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 mode
CC 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.
Reactivating CC from standby modeTo reactivate CC after it has temporarily been putin standby mode:
–Press the button (1).
> The set speed marker (4) will change color from GRAY to WHITE. The vehicle will then return to the most recently set
speed .
WARNING
There may be a significant increase in speed after the
button has been pressed.

Adaptive Cruise Control (ACC) *
ACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead.
The driver sets that desired speed and time inter- val to the vehicle ahead. When the camera andradar sensor detects a slower moving vehicleahead, your vehicle's speed is automaticallyadapted. When there are no longer slower mov-ing vehicles ahead, your vehicle will accelerate toresume the set speed. ACC is designed to follow a vehicle ahead in the same lane and maintain a time interval to thatvehicle set by the driver. If the radar sensor doesnot detect a vehicle ahead, ACC will insteadmaintain the speed set by the driver. ACC is designed to smoothly regulate speed. However, the driver must apply the brakes in sit-uations that require immediate braking. Thisapplies when there are great differences inspeed between vehicles, or if the vehicle aheadbrakes suddenly. Due to limitations in the radarsensor, braking may occur unexpectedly or not atall. Adaptive Cruise Control can follow another vehi- cle from a standstill up to 125 mph (200 km/h).Always observe posted speed limits.
WARNING
• It is advisable to read through all of the related articles pertaining to ACC (seethe list at the end of this article).
• Adaptive Cruise Control cannot cover alldriving situations and traffic, weather androad conditions.
• This system is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is responsiblefor maintaining a safe distance and speedand must intervene if Adaptive CruiseControl does not maintain a suitablespeed or suitable distance to the vehicleahead.
• Maintenance of ACC components mayonly be performed by a trained and quali-fied Volvo technician.
OverviewThe distance to the vehicle ahead (in the same lane) is monitored by a radar sensor. Your vehi-cle's speed is regulated by accelerating andbraking. The brakes may emit a sound when theyare being modulated by the adaptive cruise con-trol system. This is normal.
WARNING
•
Adaptive Cruise Control is not a collision avoidance system. The driver is alwaysresponsible for applying the brakes if thesystem does not detect another vehicle.
• Adaptive Cruise Control does not react topeople or animals, or small vehicles suchas bicycles and motorcycles. It also doesnot react to slow moving, parked orapproaching vehicles, or stationaryobjects.
• Do not use Adaptive Cruise Control indemanding driving conditions such as citydriving or other heavy traffic situations, inslippery conditions, when there is a greatdeal of water or slush on the road, duringheavy rain or snow, in poor visibility, onwinding roads or on highway on- or off-ramps.
WARNING
The brake pedal moves when the adaptive cruise control system modulates the brakes.Do not rest your foot under the brake pedal.

Collision warning
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.
