Speed-dependent steering force Speed related power steering causes the steer- ing wheel force to increase with the speed of thecar in order to give the driver enhanced sensitiv-ity.
On motorways the steering feels firmer. When parking and at low speed steering is light andrequires only a slight effort.
NOTE
In certain situations the power steering may become too hot and then needs to be tempo-rarily cooled - during this time the powersteering operates with reduced power andturning the steering wheel may then be per-ceived to be slightly heavier. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage.
Change the steering force level *To select the steering force level, go to the "Drive modes" section and see the description at thealternative INDIVIDUAL under the heading"Selectable drive modes". For the car models without a drive mode control with its INDIVIDUAL option, the selection ofsteering force is instead made via the centre dis-play's top view and the following search path:

Roll Stability Control Roll Stability Control (RSC) is a stabiliser sys- tem that minimises the risk of overturning, forexample during sudden evasive manoeuvres or ifthe car skids.
The RSC system registers if and how much the car's lateral inclination changes. This informationis used to calculate the risk of the car overturn-ing. If the car is at risk, its electronic stability con-trol system engages, the engine torque isreduced and one or more wheels are braked untilthe car has regained its stability.
WARNING
Under normal driving conditions, the RSC sys- tem improves the car's road safety, but thismust not be taken as a reason to increasespeed. Always follow the normal precautionsfor safe driving.

Speed limiter *
A speed limiter (Speed Limiter — SL) can be regarded as a reverse cruise control — thedriver regulates the speed using the acceleratorpedal but is prevented by the speed limiter fromaccidentally exceeding a pre-selected/presetmaximum speed.

WARNING
The Speed Limiter is an aid and cannot deal with all traffic, weather and road conditions. The driver must always pay attention to traffic conditions and take action when the SpeedLimiter is not maintaining a suitable speed. The driver always has the ultimate responsibil- ity for the car being driven safely and inaccordance with applicable traffic rules andregulations, even when the Speed Limiterfunction is in use.

Automatic speed limiter *
The automatic speed limiter (Automatic Speed
Limiter - ASL) function helps the driver to adaptthe car's maximum speed to the speed shownon the road signs.
The speed limiter function (Speed Limiter — SL) can be changed to automatic speed limiter. The automatic speed limiter uses speed informa- tion from the Road Sign Information 3
function to
automatically adapt the car's maximum speed.
WARNING
The automatic speed limiter function is an aid, and does not work in all driving situations,traffic, weather and road conditions. The driveralways bears responsibility for maintaining thecorrect distance and speed, as well as whenthe automatic speed limiter is being used. Even if the driver clearly sees the speed-rela- ted road sign, the speed from the Road signinformation function many be incorrect - insuch cases the driver must intervene him/herself and accelerate or brake to a suitablespeed. See also the heading "Limitations for Road sign information".

Limitations of ASLAutomatic speed limitation takes place using speed information from the RSI 3
function - not
from the speed limit road signs that the car passes. If RSI 3
cannot interpret and provide speed infor-
mation to the ASL, then the ASL is set in standby mode and changes over to SL. In such cases thedriver must intervene and brake to a suitablespeed. The ASL will be reactivated when the RSI 3
func-
tion can once again interpret and provide speed information to the ASL. See also the heading "Limitations for Road Sign Information".

Changing the tolerance for the Automatic speed limiter
The speed limiter function (Automatic Speed Limiter - ASL) can be set for different tolerancelevels.
It is possible to increase/decrease the signed speed limit. If, for example, the car follows asigned speed limit of 70 km/h (43 mph) thedriver can instead choose to allow the car tomaintain 75 km/h (47 mph).
Buttons and symbols for functions.
–Press the steering wheel button (1)
until 70 km/h (43 mph) in the centre of the speedometer (4) changes to 75 km/h(47 mph).
> After which, the car uses the selected tol- erance 5 km/h (4 mph) as long as signs passed are showing 70 km/h (43 mph). The tolerance is followed until a road sign with a lower or higher speed is passed -then the car follows the new signedspeed limit instead and the tolerance isdeleted from the memory. If the Road Sign Information * function is
activated, the signed speed limit will then be shown with a RED indicator on thespeedometer. The tolerance is adjusted in the same way as thespeed setting is in the speed limiter.
NOTE
The maximum selectable tolerance is +/- 10 km/h (5 mph).

WARNING
The Adaptive cruise control is an aid, which cannot handle all traffic, weather and roadconditions. The driver must always be observant with regard to the prevailing traffic conditions andintervene if the Adaptive cruise control doesnot maintain a suitable speed or suitable timeinterval. Read all the sections about the adaptive cruise control in the owner's manual in orderto learn about its limitations, of which thedriver should be aware before the function isused. The driver always bears responsibility for maintaining the correct time interval andspeed - even when the Adaptive cruise con-trol is being used.
Adaptive cruise control regulates the speed with acceleration and braking. It is normal for thebrakes to emit a low sound when they are beingused to adjust the speed. The adaptive cruise control aims to control the speed in a smooth way. In situations that demandsudden braking the driver must brake himself/herself. This applies in case of large speed differ- ences or if the vehicle in front brakes suddenly.Due to the limitations of the radar unit, brakingmay come unexpectedly or not at all. The adaptive cruise control aims to follow the vehicle ahead in the same lane at a time intervalset by the driver. If the radar unit cannot see anyvehicle in front then the car will instead maintainthe speed set and stored by the driver. This alsotakes place if the speed of the vehicle aheadincreases and exceeds the stored speed. The following applies for cars with automatic gearbox:
• Adaptive cruise control can follow anothervehicle at speed from 0 km/h up to200 km/h (125 mph).
The following applies for cars with manual gear-box: • The Adaptive cruise control can follow another vehicle at speeds from 30 km/h(20 mph) up to 200 km/h (125 mph).
WARNING
Adaptive cruise control is not a collision avoid- ance system. The driver must intervene if thesystem does not detect a vehicle in front. The adaptive cruise control does not brake for humans or animals, and not for small vehiclessuch as bicycles and motorcycles. Nor for lowtrailers, oncoming, slow or stationary vehiclesand objects. Do not use the Adaptive cruise control, for example, in city traffic, at junctions, on slipperysurfaces, with a lot of water or slush on theroad, in heavy rain/snow, in poor visibility, onwinding roads or on slip roads.
IMPORTANT
Maintenance of adaptive cruise control com- ponents must only be performed at a work-shop - an authorised Volvo workshop is rec-ommended.

Deactivating/activating the adaptive cruise control *
The adaptive cruise control (Adaptive Cruise Control - ACC) can be temporarily deactivatedso that it is set in the standby mode and canlater be reactivated.
Deactivate Adaptive Cruise Control and set it in standby mode
NOTE: The illustration is schematic - details may vary depending on car model.
To temporarily switch off Adaptive Cruise Control and set it in standby mode:
–Press the steering wheel button (2).
> The
symbol on the driver display
changes colour from WHITE to GREY and the stored speed in the centre of thespeedometer changes from BEIGE toGREY. In standby mode, the driver must him/herselfcontrol both speed and distance. When the adaptive cruise control is in standby mode and the car drives too close to a vehicleahead, the driver is warned about the short dis-tance by the Distance Warning function instead(see reference to the heading "Distance Warn-ing" at the end of this section).
Standby mode on driver intervention
The adaptive cruise control is temporarily deacti- vated and set in standby mode if:
• the foot brake is used
• the gear selector is moved to
N position.
• the driver maintains a speed higher than thestored speed for longer than 1 minute.
• the clutch pedal is depressed for approx. 1minute - applies to cars with manual gearbox.
In this situation, the driver must intervene andadapt the speed and distance to the vehicleahead. A temporary increase in speed with the accelera- tor pedal, e.g. during overtaking, does not affectthe setting - the car returns to the last storedspeed when the accelerator pedal is released.
Automatic standby mode
Adaptive cruise control is dependent on other systems, e.g. stability control/anti-skid ESC. If anyof these systems stops working, adaptive cruisecontrol is switched off automatically. In the event of automatic deactivation a signal willsound and a message is shown in the driver dis-play. The driver must then intervene and adaptthe speed and distance to the vehicle ahead. Automatic deactivation may occur if:
• the speed is below 5 km/h (3 mph) and ACC is uncertain whether the vehicle ahead is astationary vehicle or an object, such as aspeed bump.
• the speed is below 5 km/h (3 mph) and thevehicle ahead turns off so that ACC nolonger has a vehicle to follow.
• speed is reduced to below 30 km/h(20 mph) - only applies to cars with manualgearbox.
• the driver opens the door
• the driver takes off the seatbelt
• engine speed is too low/high
• wheels lose traction
• brake temperature is high
• the parking brake is applied
• the camera and radar unit is covered by e.g.snow or heavy rainfall (camera lens/radiowaves are blocked).

WARNING
Pilot Assist is an aid which cannot handle all traffic, weather and road conditions. The driver must always be observant with regard to the prevailing traffic conditions andintervene if Pilot Assist does not provide suit-able steering assistance or maintain a suita-ble speed or suitable time interval. Read all the sections about this function in the owner's manual in order to learn about itslimitations, of which the driver should beaware before the function is used. Pilot Assist must only be used if there are clear lane lines painted on the road surfaceon each side of the lane. All other useinvolves increased risk of contact with sur-rounding obstacles that are not detected bythe function. The driver always bears responsibility for how the car is controlled as well as for maintainingthe correct distance and speed, even whenPilot Assist is being used.
Pilot Assist regulates the speed with acceleration and braking. It is normal for the brakes to emit alow sound when they are being used to adjustthe speed. Pilot Assist attempts to regulate the speed smoothly. In situations that demand sudden brak-ing the driver must brake himself/herself. Thisapplies in case of large speed differences or ifthe vehicle in front brakes suddenly. Due to the limitations of the camera and radar unit, brakingmay come unexpectedly or not at all. Pilot Assist aims to follow the vehicle ahead in the same lane at a time interval set by the driver.If the radar unit cannot see any vehicle in frontthen the car will instead maintain the speed setand stored by the driver. This also takes place ifthe speed of the vehicle ahead increases andexceeds the stored speed. The following applies for cars with automatic gearbox:
• Pilot Assist can follow another vehicle atspeeds from 0 km/h up to 200 km/h(125 mph).
• Pilot Assist can give steering assistance fromalmost stationary up to 140 km/h (87 mph).
The following applies for cars with manual gear-box: • Pilot Assist can follow another vehicle at speeds from 30 km/h (20 mph) up to200 km/h (125 mph).
• Pilot Assist can give steering assistance from30 km/h (20 mph) up to 140 km/h(87 mph).
WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver must intervene if the systemdoes not detect a vehicle in front. Pilot Assist does not brake for people, ani- mals, objects, small vehicles (e.g. cycles andmotorcycles), low trailers as well as oncoming,slow or stationary vehicles. Do not use Pilot Assist, for example, in city traffic, at junctions, on slippery surfaces, witha lot of water or slush on the road, in heavyrain/snow, in poor visibility, on winding roads,on slip roads, or with a trailer connected tothe car.
IMPORTANT
Maintenance of Pilot Assist components must only be performed at a workshop - an author-ised Volvo workshop is recommended.
