Stability system Roll StabilityControl
The Roll Stability Control (RSC1) system helpsminimize the risk of a rollover in the event of e.g.a sudden evasive maneuver or if the vehiclebegins to skid.
The RSC system monitors the lateral angle atwhich the vehicle is leaning and registers anychanges. Using this information, the system cal-culates the likelihood of a rollover. If there is animminent risk of a rollover, Electronic StabilityControl is activated, engine torque is reduced andbrakes are applied to one or more of the wheelsuntil the vehicle has regained stability.

WARNING
The Electronic Stability Control systemESC is supplementary driver supportintended to facilitate driving and make itsafer – it cannot handle all situations inall traffic, weather and road conditions.
ESC is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
Stability control 3
This function helps control the driving and brak-ing force of each individual wheel in an attemptto stabilize the vehicle.
Spin control and active yaw control
This function is active at low speeds and brakesthe wheels that are spinning to transfer additionalpower from wheels that are not spinning.
This function also helps prevent the wheels fromspinning while the vehicle is accelerating.
Engine drag control
Engine drag control (EDC4) helps prevent inad-vertent wheel lock, e.g. after downshifting orusing engine braking when driving at low speedson a slippery surface.
Inadvertent wheel lock while driving could impairthe driver's ability to steer the vehicle.
Trailer Stability Assist * 5
Trailer Stability Assist (TSA6) is designed to helpstabilize a vehicle that is towing a trailer if thevehicle and trailer have begun to sway. For moreinformation, see "Trailer Stability Assist".
NOTE
The TSA function is deactivated if ESC SportMode is activated.

Note: The ESC system is not deactivated in this mode, but has partially reduced functionality.
ESC
Temporarily off
The ESC system's functionality has been temporarily reduced due to high brake system temperatures. Thefunction will be automatically reactivated when the brakes have cooled.

WARNING
The ASL function is supplementary driversupport intended to facilitate driving andhelp make it safer – it cannot handle allsituations in all traffic, weather and roadconditions.
Even if the driver can clearly see thespeed limit sign, the speed informationfrom the Road Sign Information (RSI)function to ASL may be incorrect. In suchcases, the driver must intervene andaccelerate or brake to an appropriatespeed.
ASL is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
See also the heading "Road Sign Infor-mation limitations".

Automatic Speed Limiter limitations
Automatic Speed Limiter (ASL) utilizes the
speed limit information provided by the RSI22
function, not from the speed limit signs that thevehicle passes.
If RSI22 is unable to interpret and provide ASLwith speed information, ASL will go into standbymode and switch over to SL. The driver will thenhave to actively brake to bring the vehicle downto the appropriate speed.
ASL will be reactivated when RSI22 is once againable to interpret and provide speed information toASL.
See “Road Sign Information limitations” for moreinformation.

For vehicles with both CC and ACC
–Change a set speed by pressing the (1)
or (3) buttons briefly or by pressing andholding them:
Press briefly: Press briefly: each presschanges the speed in +/- 5 mph(+/- 5 km/h) increments.
Press and hold: release the button whenthe set speed indicator (4) has moved tothe desired speed.
The most recently set speed will be stored.
If speed is increased by depressing the accelera-
tor pedal while pressing the (1) button onthe steering wheel, the vehicle's speed when thebutton is pressed will be stored as the set speed.
Temporarily increasing speed using the accelera-tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applyingthe brakes. On downgrades, it can sometimes bedesirable to roll a bit faster and let speed bereduced instead by engine braking alone. Thedriver can temporarily disengage the Cruise Con-trol braking function.
To disengage CC:
–Press the accelerator pedal about halfwaydown and then release it.
>Cruise Control will automatically disen-gage the automatic brake function andspeed will only be reduced using theengine braking function.
How drive mode affects cruise control
The way the cruise control maintains the vehicle'sspeed can vary depending on the selected drive
mode26.
Cruise Control Eco Cruise with ECO drive
mode
In the ECO drive mode, cruise control's accelera-tion and deceleration will be smoother than inother drive modes to help provide optimal fuelefficiency and reduced environmental impact.Because of this, the vehicle's actual speed maybe slightly above or below the set speed.
Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control'sacceleration and deceleration will be faster andmore immediate than in other drive modes.

Standby mode due to action by the driver
Cruise Control will be temporarily deactivated andput in standby mode if:
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's speed.
Temporarily increasing speed using the accelera-tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic standby mode
Cruise Control will be temporarily deactivated andput in standby mode 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's speed.

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 to regu-late speed smoothly. The driver must apply thebrakes in situations requiring immediate braking.For example, 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 is designed to follow avehicle ahead in the same lane and maintain atime interval to that vehicle set by the driver. If theradar sensor does not detect a vehicle ahead, itwill instead maintain the speed set by the driver.This will also happen if the speed of the vehicleahead exceeds the set speed for your vehicle.
Adaptive Cruise Control can follow anothervehicle at speeds from a standstill up to200 km/h (125 mph).
WARNING
Adaptive Cruise Control is not a collisionavoidance system. The driver is alwaysresponsible and must intervene if the sys-tem fails to detect a vehicle ahead.
Adaptive Cruise Control does not brakefor people or animals and does not brakefor small vehicles, such as bikes andmotorcycles. Similarly, it does not brakefor low trailers, oncoming, slow-moving orstationary vehicles and objects.
Do not use Adaptive Cruise Control indemanding situations, such as in city traf-fic, at intersections, on slippery surfaces,with a lot of water or slush on the road, inheavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
CAUTION
Maintenance of Adaptive Cruise Control com-ponents may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.
