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.

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.

Adaptive Cruise Control – setting speed
Setting a speedOnce ACC has been put in standby mode:
Controls and display
Put in active mode and set a speed (each additional press increases/decreasesspeed by 1 mph (approximately 2 km/h))
• Press
or (4).
> The set speed, for example 60 mph (5), will be magnified for several seconds and the frame around the speed will changecolors from white to green to indicate
that this speed has been stored (set).
When this symbol has changed col-ors from white to green , ACC is in
active mode and the vehicle will
maintain the set speed.
This symbol indicates that you are approaching a vehi-cle ahead. ACC will switch from main- taining a set speed to main-
taining a set distance from
that vehicle.
When this happens, a speed range will be indicated on
the speedometer: The higher speed (the cur-
rently set speed (5)) will be marked in green.
The lower speed in the range is the speed of
the vehicle ahead.
Changing the set speed
• After a speed has been set, it can be increased or decreased by briefly press- ing the
or buttons. Each time one
of these buttons is pressed, the vehicle's speed changes by 5 mph or 5 km/h. If thespeed is increased by pressing the accel-erator pedal, the vehicle's speed whenthe button is pressed will be set.
• Press and hold one of these buttons toincrease/decrease the speed in 1-mph or1-km/h increments. Release the buttonwhen you have reached the desiredspeed.
NOTE
•If one of the Adaptive Cruise Control buttons is pressed for more thanapproximately one minute, ACC will bedeactivated. The engine must then beswitched off and restarted to resetACC.
• In some situations Adaptive CruiseControl cannot be put in active mode.

WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Standby mode due to action by the driver
ACC is temporarily deactivated and put in standby mode:
• if the brakes are applied
• if the gear selector is moved to
N
• if the driver drives faster than the set speed for more than
1 minute.
In this happens, the driver will have to regu- late the vehicle's speed.
NOTE
If the accelerator pedal is only depressed for a short time, such as when passinganother vehicle, ACC is deactivated tem-porarily and is reactivated when the pedalis released.
Automatic standby modeACC is linked to other systems such as the stability system. If this system is not function-ing properly, ACC will switch off automati-cally. In the event of automatic deactivation, an audible signal will sound and the message
Cruise control Cancelled is shown in the
instrument panel. The driver must then inter- vene and adapt the vehicle's speed to thesurrounding traffic and regulate the distanceto the vehicle ahead. An automatic switch to standby mode may be caused if:
• engine speed (rpm) is too high/low
• The driver's door is opened
• The driver unbuckles his/her seat belt
• the vehicle's speed goes below 18 mph (30 km/h)
• the wheels lose traction
• brake temperature is high
• the radar sensor is obstructed by, forexample, wet snow or rain.
Resuming the set speedIf ACC is in standby mode, it can be reactiva- ted by pressing the
button on the steering
wheel keypad. The vehicle will return to the most recently set speed.
WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Turning ACC off completely
Controls and display
Resume previous settings.
Off/On/Standby mode
• From standby mode, press (2)
once.
• From active mode, press (2)
twice.
The set speed and time interval are then cleared from the system's memory and can- not be resumed by pressing (1)
.

The driver will then have to reactivate ACC in one of the following ways:
• By pressing
•By accelerating up to at least 3 mph (4 km/h). ACC will then resume followingthe vehicle ahead.
Your vehicle will then resume following the vehicle ahead at the set time interval.
NOTE
ACC can remain active and keep your vehicle at a standstill for up to 4 minutes.After 4 minutes have elapsed, the parkingbrake will be engaged and ACC will go intostandby mode. To reactivate ACC, the driver must release the parking brake (see Parking brake –general information (p. 254)).
Automatic standby mode when ACC changes target vehicles
If the vehicle ahead turns suddenly, there may be a stationary vehicle ahead The following only applies at speeds below approximately 18 mph (30 km/h)
:
If ACC changes target vehicles (the vehicle that the radar sensor has detected) from amoving vehicle to a stationary one, the sys-tem will apply the brakes in your vehicle.
WARNING
At speeds above 18 mph (30 km/h), ACC
will not react to a stationary vehicle and apply the brakes but will instead acceler-ate to the previously set speed. The drivermust actively apply the brakes to stop thevehicle.
ACC disengages and goes into standby mode if:
• Your vehicle's speed goes below 10 mph (15 km/h) and ACC cannot determine ifthe target object is a stationary vehicle orsome other type of object such as e.g., aspeed bump.
• Your vehicle's speed goes below 10 mph(15 km/h) and the vehicle ahead turns sothat ACC no longer has a target vehicle tofollow.
No automatic braking when at a standstill
In certain situations, ACC will no longer apply the brakes and go into standby mode whilethe vehicle is not moving. This means that thedriver will have to apply the brakes. This happens if:
• The driver presses the brake pedal
• The parking brake is activated
• The gear selected is moved to
P, N or R
• The driver presses the
button to put
ACC in standby mode
The parking brake is applied automatically
In certain situations, ACC will apply the park- ing brake in order to continue keeping thevehicle at a standstill. This happens if:
• The driver opens the door or takes off his/her seat belt
• The stability system is put in Sport mode(see Stability system – operation (p. 163))
• ACC has kept the vehicle at a standstillfor more than 2 minutes
• The engine has been switched off
• The brakes have overheated

City Safety – operation
Using City Safety™
NOTE
The City Safety™ function is activated automatically each time the engine hasbeen switched off and restarted.
On and OffIn certain situations, it may be desirable to switch City Safety™ off, such as when drivingin close quarters where leaves, branches, etc.may obscure the hood and windshield. When the engine is running, City Safety™ can be switched off as follows: Press My Car in the center console control
panel and go to
SettingsCar settings
Driver support systemsCity Safety.
Select
Off.
If the engine is switched off, City Safety™ will reactivate when the engine is restarted.
WARNING

City Safety – limitations
Limitations
WARNING
The laser sensor has certain limitations and its function may be reduced (or it maynot function at all) in conditions such asheavy rain or snowfall, or by dense fog orthick, blowing dust or snow. Condensa-tion, dirt, ice or snow on the windshieldmay also interfere with the sensor’s func-tion.
The sensor used by City Safety™ is designed to detect cars and other larger motor vehiclesahead of your vehicle in both daylight anddarkness. Objects such as warning flags hanging from long objects on the roof or accessories suchas auxiliary lights or protective arches on thefront of the vehicle that are higher than thehood may also impede the sensor’s function. Braking distance to the vehicle ahead increa- ses on slippery road surfaces, which mayreduce City Safety’s capacity to avoid a colli-sion. In situations like this, the stability sys-tem (see Stability system – introduction(p. 162)) will help provide the best possiblebraking capacity and stability. City Safety™ emits a laser beam and meas- ures the way in which the light is reflected.
