Electronic Stability Control (ESC)sport mode
ESC is always activated and cannot be switchedoff.
However, the driver can select Sport mode,which offers more active driving characteristics.
In Sport mode, the engine management systemmonitors movement of the accelerator pedal andsteering wheel for sportier driving and allowsmore lateral movement of the rear wheels beforeESC is triggered.
Under certain circumstances, such as when driv-ing with snow chains, or driving in deep snow orloose sand, it may be advisable to temporarily useSport mode for maximum tractive force.
If the driver releases pressure on the acceleratorpedal, ETC will also activate to help stabilize thevehicle.

Activating/deactivating Sport mode
In the center display's Functionview, tap ESC Sport Mode.The green indicator light in thebutton will illuminate to showthat the function has been acti-vated or gray when the functionis deactivated.
When Sport mode is activated, thissymbol will illuminate in the instrumentpanel. It will remain on until the driverdeactivates the function. ETC will alsoreturn to normal mode when the engine is restar-ted.

Roll stability control (RSC)
Volvo's Roll Stability Control (RSC) is a stabilitysystem designed to help minimize the risk of arollover in emergency maneuvers or if a skidshould occur.
RSC uses a gyroscopic sensor that registers theamount of change in the lateral angle at whichthe vehicle is leaning. Using this information, RSCcalculates the likelihood of a rollover. If there isan imminent risk of a rollover, the stability systemis activated, power to the engine is cut and thebrakes are applied to one or more of the wheelsuntil the vehicle regains stability.

NOTE
Before CC can be activated, the vehicle'sspeed must be at least 20 mph (30 km/h).This is also the lowest speed that can be set.

Activating CC (putting it in active mode
and setting a speed)
–With the symbol displayed (CC is in
standby mode), press the button (2) onthe left-side steering wheel keypad.
>This puts CC in active mode and willmaintain the vehicle's current speed.

Changing Cruise Control speed
Changing a set speed
Function buttons and symbols (generic illustration)
–Change a set speed by pressing the (1)or — (3) buttons briefly or by pressing andholding them:
•Press briefly: changes speed in+/– 5 mph (+/– 5 km/h) increments.Each press changes the vehicle's speedby +/– 5 mph (+/– 5 km/h).
•Press and hold: changes the speed+/– 1 mph (+/– 1 km/h) at a time.Release the button when the set speedindicator (4)/(6) has moved to the desiredspeed.
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 whenpassing 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. halfwaydown and release it.
>CC will automatically deactivate the auto-matic brake function and will then onlyuse the engine braking function.

A temporary increase in speed, such as whenpassing 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 thevehicle's speed.
