the stored maximum speed with a col- oured mark (5) and the driver can tem-porarily exceed the set maximumspeed - the mark (5) changes colourduring this time from GREEN toWHITE. The speed limiter is automatically reac- tivated after the release of the acceler-ator pedal and the car's speed isslowed down to below the selected/stored maximum speed - the display'smark (5) changes colour from WHITEto GREEN and the car's maximumspeed is again limited.

Speed limiter* - alarm for speed exceeded
A (Speed Limiter) can be regarded as a reverse cruise control - the driver regulatesthe speed using the accelerator pedal but isprevented from accidentally exceeding apre-selected/set speed by the speed limiter. On a steep downhill gradient the speed limit- er's engine braking effect may be inadequateand the selected maximum speed is excee-ded. The driver is alerted about this with anacoustic signal. The signal is active until the driver has slowed to below the selected maximum speed.
NOTE
The alarm is only activated after 5 seconds if the speed has been exceeded by at least3 km/h provided that none of the buttons
or has been depressed during the
last half minute.

Adaptive cruise control - ACC*
The adaptive cruise control (ACC – Adaptive Cruise Control) helps the driver to maintain aneven speed and a safe distance from the vehi-cle ahead. The adaptive cruise control provides a more relaxing driving experience on long journeyson motorways and long straight main roads insmooth traffic flows. The driver sets the desired speed (p. 191) and time interval (p. 192) to the car in front.When the radar detector detects a slowervehicle in front of the car, the speed is auto-matically adapted to that. When the road isclear again the car returns to the selectedspeed. If the adaptive cruise control is switched off or set to standby mode (p. 193) and the carcomes too close to a vehicle in front, then thedriver is warned instead by the DistanceWarning (p. 202) function about the shortdistance.WARNING
The driver must always be observant with regard to the traffic conditions and inter-vene when the adaptive cruise control isnot maintaining a suitable speed or suita-ble distance. The adaptive cruise control cannot handle all traffic, weather and road conditions. Read all the sections about the adaptive cruise control in the owner's manual inorder to learn about its limitations, ofwhich the driver should be aware before itis used. The driver always bears responsibility for maintaining the correct distance andspeed, even when the adaptive cruise con-trol is being used.
IMPORTANT
Maintenance of adaptive cruise control components must only be performed at aworkshop - an authorised Volvo workshopis recommended.
Automatic gearboxCars with automatic gearbox have enhanced functionality with the adaptive cruise control'sQueue Assist (p. 195).

Adaptive cruise control* - function
The adaptive cruise control (ACC – Adaptive Cruise Control) helps the driver to maintain aneven speed and a safe distance from the vehi-cle ahead. It consists of a cruise control sys-tem and a coordinated spacing system.
Function overview

.
Warning lamp - braking by driver required
Steering wheel keypad (p. 190)
Radar sensor (p. 197)
WARNING
Adaptive cruise control is not a collision avoidance system. The driver must inter-vene if the system does not detect a vehi-cle in front. The adaptive cruise control does not brake for humans or animals, and not for smallvehicles such as bicycles and motorcy-cles. Nor for oncoming, slow or stationaryvehicles and objects. Do not use the adaptive cruise control, for example, in city traffic, in dense traffic, atjunctions, on slippery surfaces, with a lotof water or slush on the road, in heavyrain/snow, in poor visibility, on windingroads or on slip roads.
Distance to the vehicle ahead (p. 192) is measured primarily by a radar sensor (p.197). Cruise control regulates the speed withacceleration and braking. It is normal for thebrakes to emit a low sound when they arebeing used by the adaptive cruise control.
WARNING
The brake pedal moves when Cruise Con- trol brakes. Do not rest your foot beneaththe brake pedal as it may become trapped.
The adaptive cruise control aims to follow the vehicle ahead in the same lane at a time inter-val set by the driver. If the radar sensor can-not see any vehicle in front then the car willinstead maintain the cruise control's setspeed. This also happens if the speed of thevehicle in front exceeds the cruise control'sset speed. The adaptive cruise control aims to control the speed in a smooth way. In situations thatdemand sudden braking the driver mustbrake himself/herself. This applies with largedifferences in speed, or if the vehicle in frontbrakes heavily. Due to limitations in the radarsensor (p. 197) braking may come unexpect-edly or not at all. The adaptive cruise control can be activated to follow another vehicle at speeds from 30 km/h 7
up to 200 km/h. If the speed falls
below 30 km/h or if the engine speed becomes too low, the cruise control is set instandby mode (p. 193) at which automaticbraking ceases - the driver must then takeover himself/herself to maintain a safe dis-tance to the vehicle ahead.
Warning lamp - braking by driver required
Adaptive cruise control has a braking capacity that is equivalent to more than 40%of the car's braking capacity.
6 NOTE: The illustration is schematic - details may differ depending on car model.
7 Queue Assistant (p. 195) (in cars with automatic gearbox) can operate in the range of 0-200 km/h.

If the car needs to be braked more heavily than cruise control capacity and the driverdoes not brake, then cruise control uses thewarning lamp and warning sound from theCollision warning system (p. 212) in order toalert the driver that immediate intervention isrequired.
NOTE
The warning lamp may be difficult to see in strong sunlight or when wearing sun-glasses.
WARNING
Cruise Control warns only of vehicles which the radar sensor has detected.Hence the warning may not be given, or itmay be given with a certain delay. Do notwait for a warning without braking when sorequired.
Steep roads and/or heavy loadBear in mind that the adaptive cruise control is primarily intended for use when driving onlevel road surfaces. It may have difficulty inkeeping the correct distance from the vehicleahead when driving on steep downhill slopes,with a heavy load or with a trailer - in whichcase, be extra attentive and ready to slowdown.

Adaptive cruise control* - managing speed
The adaptive cruise control (ACC – Adaptive Cruise Control) helps the driver to maintain aneven speed and a safe distance from the vehi-cle ahead. To enable cruise control:
• Press the steering wheel button
- a
similar WHITE symbol illuminates in the combined instrument panel (8) whichshows that cruise control is in standbymode (p. 193).
To activate cruise control: • At the required speed - press the steering wheel button
or .
> The current speed is stored in the mem- ory, the combined instrument panel shows a "magnifying glass" around theselected speed for a second or so and itsmarking changes from WHITE to GREEN.
When this symbol changes colourfrom WHITE to GREEN, the cruisecontrol is active and the car main-
tains the stored speed.
Only when the symbol shows an image of another vehicleis the distance to the vehicle
in front controlled by thecruise control.

The same symbol is also shown when Dis- tance Warning (p. 202) function is activated.
NOTE
Only use the time intervals permitted by local traffic regulations. If Cruise Control does not appear to react when activated, this may be because thetime distance to the car in front is prevent-ing an increase in speed. The higher the speed the longer the calcu- lated distance in metres for a given timeinterval.

Adaptive cruise control* - temporary deactivation, and standby mode
The adaptive cruise control (ACC – Adaptive Cruise Control) helps the driver to maintain aneven speed and a safe distance from the vehi-cle ahead. The cruise control can be tempo-rarily deactivated and set in standby mode.
Temporary deactivation - standby mode
with Speed limiter
To temporarily disengage the adaptive cruisecontrol and set it in standby mode:
• Press the steering wheel button
This symbol and the stored speed's marking then change colour fromGREEN to WHITE.
Temporary deactivation - standby mode without Speed limiter
To temporarily disengage the adaptive cruise control and set it in standby mode:
• Press the steering wheel button
Standby mode due to driver interventionCruise control is temporarily disengaged and set in standby mode if:
• the foot brake is used
• the clutch pedal is depressed for longer than 1 minute 9 •
the gear selector is moved to
N position
(automatic gearbox)
• the driver maintains a speed higher than the set speed for longer than 1 minute.
The driver must then regulate the speed. A temporary increase in speed with the accel- erator pedal, e.g. during overtaking, does notaffect the cruise control setting - the carreturns to the last stored speed when theaccelerator pedal is released.
Automatic standby modeThe adaptive cruise control is dependent onother systems, e.g. DSTC (Stability and trac-tion control system) (p. 175). If any of thesesystems stop working then cruise control isautomatically deactivated. In the event of automatic deactivation a signal will sound and the message
Cruise control
Cancelled is shown in the combined instru-
ment panel. The driver must then intervene and adapt the speed and distance to thevehicle ahead. An automatic deactivation can be due to:
• the driver opens the door
• the driver takes off his seatbelt
• engine speed is too low/high
• speed has fallen below 30 km/h 10

Disengaging and selecting a higher or lower gear does not involve standby mode.
10 Does not apply to a car with Queue Assistant - it manages right down to stationary.
