Active chassis* (Four C)
Active chassis, Four-C (Continuously Controlled Chassis Concept), regulates thecharacteristics of the shock absorbers so thatthe vehicle's driving characteristics can beadjusted. There are three settings: Comfort,Sport and Advanced.
Operation
Chassis settings
Use the buttons in the center console to change setting. The setting in use when theengine is switched off is activated the nexttime the engine is started.
ComfortComfort mode offers a somewhat softer ride and the transmission shifts gears at lowerrpm. This mode is particularly suitable forlong-distance highway driving. The indicatorlight in the button will be on when this modeis selected.
SportIn this mode, the vehicle's body sway is reduced during cornering and steeringresponse is more immediate. The transmis-sion shifts up at higher rpm for sportier driv-ing. The indicator light in the button will be onto indicate that Sport mode has beenselected.
AdvancedIn this mode, body sway in curves is minimal and steering response is very direct. Gearshifting is done at high rpm in each gear fordynamic and active driving.

Stability system – introduction
The Electronic Stability Control (ESC) system consists of a number of functions designed tohelp reduce wheel spin, counteract skiddingand to generally help improve directional sta-bility.
A pulsating sound will be audiblewhen the system is actively operat-ing and is normal. Acceleration willalso be slightly slower than normal.
WARNING
ESC is a supplementary aid and cannot deal with all situations or road conditions. The driver is always responsible for oper- ating the vehicle in a safe manner inaccordance with current traffic regulations.
ESC consists of the following functions:
• Traction control
• Spin control
• Active Yaw Control
Traction Control (TC)This function is designed to help reduce wheel spin at low speeds by transferringpower from a drive wheel that begins to losetraction to the wheel on the opposite side ofthe vehicle (on the same axle).

Spin Control (SC)The SC function is designed to help prevent the drive wheels from spinning while the vehi-cle is accelerating.
Active Yaw Control (AYC)This function helps maintain directional stabil- ity, for example when cornering, by brakingone or more of the wheels if the vehicleshows a tendency to skid or slide laterally.
Trailer Stability Assist (TSA)The TSA helps stabilize a vehicle that is tow- ing a trailer when the vehicle and trailer havebegun to sway. See Trailer Stability Assist(TSA) (p. 268) for more information. This system is automatically deactivated if the driver selects Sport mode.

Stability system – operation
Operation
Sport modeThe stability system is always activated and cannot be switched off.
However, the driver canselect Sport mode, which
offers more active drivingcharacteristics. Sport mode can be selected
in the MY CAR menus, see
My Car – introduction (p. 70).
In Sport mode, the engine management sys-
tem monitors movement of the accelerator pedal and steering wheel for sportier drivingby allowing more lateral movement of the rearwheels before ESC is activated. Under certain circumstances, such as when driving with snow chains, or driving in deepsnow or loose sand, it may be advisable totemporarily use Sport mode for maximum
tractive force. If the driver releases pressure on the acceler- ator pedal, ETC will also activate to help sta-bilize the vehicle. To switch to Sport mode:
Sport mode remains active until the driver
switches it off in the menu or until the engine is switched off. ETC will return to normalmode when the engine is restarted.

–Press the
CRUISE button (1).
> The symbol
illuminates and the text
(---) mph (5) indicates that cruise con-
trol is in standby mode.
NOTE
Putting cruise control in standby mode does not set a cruising speed.
Setting a speed
Use the or buttons set the vehicle's
current speed. The set speed is shown in the display.
NOTE
Cruise control cannot be engaged at speeds below 20 mph (30 km/h).
Adjusting the set speedAfter a speed has been set, it can be increased or decreased by using the
or buttons. 1. Press
or briefly and release the
button to increase or decrease vehicle speed by approximately 1 mph or 1 km/h.
> This will become the set speed when the button is released.
2. Press and hold one of these buttons to increase/decrease the speed in 1-mph or 1-km/h increments. Release the buttonwhen you have reached the desiredspeed.
NOTE
•A temporary increase in speed by pressing the accelerator pedal, for lessthan 1 minute (e.g. when passinganother car), does not affect the cur-rent cruise control setting. The vehiclewill automatically return to the previ-ously set speed when the acceleratorpedal is released.
• If one of the cruise control buttons iskept depressed for more than approx.1 minute cruise control is disengaged.The engine must then be switched offin order to reset cruise control.

Toggling between ACC and CC (standard Cruise Control)
Adaptive Cruise Control (ACC) helps the driver maintain a safe distance/time interval tothe vehicle ahead.
Switching from ACC to CCThis may be useful if, for example, the radarsensor is obstructed in some way. SeeAdaptive Cruise Control – limitations (p. 180)for additional information.
• Press and hold the
button; the symbol
in the instrument panel will switch from
to .
> This activates the standard cruise control function (see Cruise control (CC) – intro- duction (p. 168)).
WARNING
Switching from ACC to CC means that:
• Your vehicle will
no longer automati-
cally maintain a set distance to a vehi- cle ahead.
• Only the set speed will be maintainedand the driver will have to apply thebrakes when needed.
Switching from CC to ACC
Switch off cruise control by pressing once
or twice as needed according to the instruc- tions in the previous section "Turning ACC off completely." The next time the system isswitched on, ACC will be reactivated.

Adaptive Cruise Control – introduction
ACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead. It is primar-ily intended for use on long straight roads insteady traffic, such as on highways and othermain roads. When the driver has set the desired speed and the time interval to the vehicle ahead,ACC functions as follows:
• If there are no other vehicles in the lane ahead of you, your vehicle will travel atthe set speed.
• If ACC's radar sensor detects a slowermoving vehicle in the lane ahead, the sys-tem will adapt your vehicle's speed tohelp maintain the set time interval to thevehicle ahead. When there are no longerslower moving vehicles ahead, your vehi-cle will accelerate to resume the setspeed.
If ACC is switched off completely or in standby mode and your vehicle comes tooclose to another vehicle ahead, the driver willbe warned by the Distance Alert system (seeDistance Alert – introduction (p. 185)).WARNING
• Adaptive Cruise Control cannot cover all driving situations and traffic,weather and road conditions. The"Function" section provides informa-tion about limitations that the drivermust be aware of before using thisfeature.
• This system is designed to be a sup-plementary driving aid. It is not, how-ever, intended to replace the driver'sattention and judgement. The driver isresponsible for maintaining a safe dis-tance and speed and must intervene ifAdaptive Cruise Control does notmaintain a suitable speed or suitabledistance to the vehicle ahead.
• Maintenance of ACC components mayonly be performed by a trained andqualified Volvo technician.

WARNING
• Adaptive Cruise Control is not a colli- sion avoidance system. The driver isalways responsible for applying thebrakes if the system does not detectanother vehicle.
• Adaptive Cruise Control does not reactto people or animals, or small vehiclessuch as bicycles and motorcycles. Italso does not react to slow moving,parked or approaching vehicles, orstationary objects.
• Do not use Adaptive Cruise Control indemanding driving conditions such ascity driving or other heavy traffic situa-tions, in slippery conditions, whenthere is a great deal of water or slushon the road, during heavy rain orsnow, in poor visibility, on windingroads or on highway on- or off-ramps.
The distance to the vehicle ahead (in the same lane) is monitored by a radar sensor.Your vehicle's speed is regulated by acceler-ating and braking. The brakes may emit asound when they are being modulated by theadaptive cruise control system. This is nor-mal.
WARNING
The brake pedal moves when the adaptive cruise control system modulates thebrakes. Do not rest your foot under thebrake pedal.
The ACC system is designed to smoothly regulate speed. However, the driver mustapply the brakes in situations that requireimmediate braking. This applies when thereare great differences in speed between vehi-cles, or if the vehicle ahead brakes suddenly.
WARNING
Due to limitations in the radar sensor, braking may occur unexpectedly or not atall, see Adaptive Cruise Control – limita-tions (p. 180).
Adaptive Cruise Control can be put in active mode at any permitted speed. However, if thevehicle's speed falls below 18 mph (30 km/h)or if engine speed (rpm) becomes too low,ACC disengages (goes into standby mode)and will no longer modulate the brakes. Thedriver will then have to maintain a safe dis-tance to the vehicle ahead.
WARNING
When Adaptive Cruise Control is in standby mode or is switched off com-pletely, the brakes will not be modulatedautomatically. The driver must assume fullcontrol over the vehicle.
Warning light—driver braking requiredAdaptive Cruise Control can exert brake force that is equivalent to approximately 40% ofthe vehicle's total braking capacity. In situa-tions requiring more brake force than ACCcan provide and if the driver does not applythe brakes, an audible signal from the Colli-sion Warning system will sound and warninglight will illuminate (see Collision warning* –function (p. 198)) in the windshield to alertthe driver to react.
NOTE
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if thedriver is not looking straight ahead maymake the visual warning signal in the wind-shield difficult to see.
