The systems can, for example, help the driver:
maintain a set speed
maintain a set time interval to the vehicle ahead
help prevent a collision by warning thedriver and applying the brakes
park the vehicle.
Some of the systems are standard and othersare options. This also varies from market tomarket.

Speed-dependent steering wheel resistance Speed-dependent power steering increases the steering wheel resistance in pace withthe vehicle's speed, which can help give thedriver an enhanced feeling of control and sta-bility.
Steering is stiffer on highways. When parking and at low speeds, it will be easier to movethe steering wheel.
NOTE
In rare situations, the power steering may become too hot andrequire temporary cooling – dur-ing such time the power steering
will work at reduced output and the steer-ing wheel may feel more difficult to move. The message
Power steering Assistance
temporarily reduced will be displayed
along with this symbol in the instrument panel.
While the power steering is working at reduced power, the driver support func-tions and systems with steering assistanceare not available.

Electronic Stability Control
The Electronic Stability Control (ESC 1
) func-
tion helps the driver avoid skidding and improves the vehicle's directional stability.
This symbol will be displayed in the instrument panel whenthe system is intervening. When the system has inter- vened to apply the brakes, apulsing sound may be heard
and the vehicle may accelerate more slowlythan expected when the accelerator pedal isdepressed.
The system consists of the following sub-func- tions:
Stability control 2
Spin control and active yaw control
Engine drag control
Trailer Stability Assist
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.

Stability system
The Roll Stability Control (RSC 10
) system
helps reduce the risk of a rollover in the event of e.g. a sudden evasive maneuver or if thevehicle begins to skid.
The system monitors the lateral angle at which the vehicle is leaning and registers anychanges. Using this information, the systemcalculates the likelihood of a rollover. If there isan imminent risk of a rollover, Electronic Sta-bility Control is activated, engine torque isreduced and brakes are applied to one or moreof the wheels until the vehicle has regainedstability.

Using engine braking instead of applying the brakes
Cruise Control regulates speed by lightly applying the brakes. On downgrades, it cansometimes be desirable to roll a bit faster andlet speed be reduced instead by engine brak-ing alone. The driver can temporarily disen-gage the Cruise Control braking function. To disengage CC:
–Press the accelerator pedal about halfway down and then release it.
> Cruise Control will automatically disen-
gage the automatic brake function and speed will only be reduced using theengine braking function.

Cruise control standby mode Cruise control (CC 18
) can be deactivated and
put in standby mode. This may happen auto- matically or be due to driver intervention.
Standby mode means that the function is selected in the instrument panel but not acti-vated. In standby mode, cruise control will notregulate speed.
Standby mode due to action by the
driver
Cruise control will be deactivated and put instandby mode if any of the following 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.
The driver must then control the vehicle'sspeed. 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.
Automatic standby modeAdaptive Cruise Control may go into standbymode if:
the wheels lose traction
the engine speed (rpm) is too low/high
the temperature in the brake systembecomes too high
the vehicle's speed goes below 30 km/h(20 mph).
The driver must then control the vehicle'sspeed.

Adaptive Cruise Control (ACC 20
) helps the
driver maintain a constant speed with a set time interval to the vehicle ahead.
Adaptive Cruise Control can help provide a more relaxed driving experience on long tripson highways or long, straight roads with eventraffic flows.
The camera/radar sensor measures the distance to the vehicle ahead.
The driver sets a speed and a time interval to the vehicle ahead. If the camera/radar sensordetects a slower-moving vehicle ahead, yourvehicle's speed will be automatically adaptedaccording to the set time interval to that vehi-cle. When there are no longer slower-moving

vehicles ahead, the vehicle will return to the set speed. If the Curve Speed Assist (CSA)

activated, it may also affect the vehicle's speed.
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.
Adaptive Cruise Control regulates speed byaccelerating and braking. It is normal for thebrakes to emit a slight sound when they arebeing used to adjust speed. Adaptive Cruise Control always attempts toregulate speed smoothly. The driver mustapply the brakes in situations requiring imme-diate braking. For example, when there aregreat differences in speed between vehicles orif the vehicle ahead brakes suddenly. Due tolimitations in the radar sensor, braking mayoccur unexpectedly or not at all. Adaptive Cruise Control is designed to follow a vehicle ahead in the same lane and maintaina time interval to that vehicle set by the driver.If the radar sensor does not detect a vehicleahead, it will instead maintain the speed setby the driver. This will also happen if the speedof the vehicle ahead exceeds the set speed foryour vehicle.
CAUTION
Only a workshop may perform mainte- nance on driver support components – anauthorized Volvo workshop is recom-mended.

standby
mode Adaptive Cruise Control (ACC 28
) 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
* function.
Automatic standby modeAdaptive Cruise Control is dependent on other systems, such as Electronic Stability Control (ESC 29
). If any of these other systems stops
working, Adaptive Cruise Control will be auto- matically deactivated.
WARNING
With automatic standby mode, the driver is warned by an acoustic signal and a mes-sage on the instrument panel.
The driver must then regulate vehicle speed, apply the brakes if necessary,and maintain a safe distance to othervehicles. Adaptive Cruise Control may go into standbymode if:
your vehicle's speed goes below 5 km/h(3 mph) and ACC cannot determine if thevehicle ahead is stationary or if it isanother object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns sothat ACC no longer has a vehicle to follow.
the driver opens the door.
the driver unbuckles the seat belt.
the engine speed (rpm) is too low/high.
one or more of the wheels lose traction.
the brake temperature is high.
the parking brake is applied.
the camera/radar sensor is covered bysnow or heavy rain (the camera lens/radarwaves are blocked).Related information
