–Press the
CRUISE button (1).
> The symbol
illuminates and the text(---) mph (5) indicates that cruise control
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 cur-
rent 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 but-
ton 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 button whenyou have reached the desired speed.
NOTE
• A temporary increase in speed by press- ing the accelerator pedal, for less than1 minute (e.g. when passing another car),does not affect the current cruise controlsetting. The vehicle will automaticallyreturn to the previously set speed whenthe accelerator pedal 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 off inorder 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 to the vehi-cle ahead.
Switching from ACC to CCThis may be useful if, for example, the radar sen- sor is obstructed in some way. See AdaptiveCruise Control – limitations (p. 194) for addi-tional 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) – introduc- tion (p. 181)).
WARNING
Switching from ACC to CC means that:
• Your vehicle will
no longer automatically
maintain a set distance to a vehicle ahead.
• Only the set speed will be maintained andthe driver will have to apply the brakeswhen needed.
Switching from CC to ACC
Switch off cruise control by pressing once or
twice as needed according to the instructions in
DRIVER SUPPORT

the previous section "Turning ACC off com- pletely." The next time the system is switched on,ACC will be reactivated.

Cruise control (CC) – deactivating Cruise control is designed to assist the driver by maintaining a set speed. It is primarily intendedfor use on long straight roads in steady traffic,such as on highways and other main roads.
Automatic deactivationThe cruise control is automatically deactivated temporarily
if one of the following occurs:
• If the speed drops below approximately 20 mph (30 km/h).
• When the brake pedal is depressed.
• If the gear selector is moved to position
N.
• During wheel spin or wheel lock-up.
• If the vehicle's speed is increased by usingthe accelerator pedal for more than 1 minute.
• Engine speed (rpm) is too high or too low.
The currently set speed will be saved in the sys-tem's memory.
Temporary deactivationThe driver can temporarily deactivate the cruise control by pressing 0. The saved speed is shown
in brackets in the information display.
Resume set speedIf the cruise control has been deactivated tempo- rarily, it can be reactivated by pressing
. The
vehicle's speed returns to the most recently set speed.
WARNING
There may be a significant increase in speed after the
button has been pressed.
Deactivation
The Cruise control is disengaged by pressing or by switching off the engine. The set speed is cleared.
WARNING
Cruise control should not be used in heavy traffic or when driving on wet or slipperyroads. Cruise control may not maintain setspeed on steep downgrades.

Adaptive Cruise Control – introductionACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead. It is primarilyintended for use on long straight roads in steadytraffic, such as on highways and other mainroads.
When the driver has set the desired speed and the time interval to the vehicle ahead, ACC func-tions as follows:
• If there are no other vehicles in the laneahead of you, your vehicle will travel at theset speed.
• If ACC's radar sensor detects a slower mov-ing vehicle in the lane ahead, the system willadapt your vehicle's speed to help maintainthe set time interval to the vehicle ahead.When there are no longer slower movingvehicles ahead, your vehicle will accelerate toresume the set speed.
If ACC is switched off completely or in standbymode and your vehicle comes too close toanother vehicle ahead, the driver will be warnedby the Distance Alert system (see Distance Alert– introduction (p. 199)).
WARNING
• Adaptive Cruise Control cannot cover all driving situations and traffic, weather androad conditions. The "Function" sectionprovides information about limitations thatthe driver must be aware of before usingthis feature.
• This system is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is responsiblefor maintaining a safe distance and speedand must intervene if Adaptive CruiseControl does not maintain a suitablespeed or suitable distance to the vehicleahead.
• Maintenance of ACC components mayonly be performed by a trained and quali-fied Volvo technician.

WARNING
Adaptive Cruise Control only warns of vehicles detected by the radar sensor, see AdaptiveCruise Control – limitations (p. 194). In somecases there may be no warning or the warn-ing may be delayed. The driver should alwaysapply the brakes when necessary.
Steep inclines and/or heavy loadsACC is primarily intended for use on fairly level roads. The system may have difficulty maintainingthe correct distance to a vehicle ahead on steepinclines, if the vehicle is carrying a heavy load oris towing a trailer. In these situations, the drivershould always be prepared to apply the brakes ifnecessary.

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/decreases speedby 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 change colors from white to green to indicate that this
speed has been stored (set).
When this symbol has changed colorsfrom white to green , ACC is in active
mode and the vehicle will maintain the
set speed.
This symbol indicates that you are approaching a vehicleahead. ACC will switch from maintain- ing a set speed to maintaining
a set distance from that vehi-
cle.
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 pressing the
or buttons. Each time one of
these buttons is pressed, the vehicle's speed changes by 5 mph or 5 km/h. If the speed isincreased by pressing the accelerator pedal,the vehicle's speed when the button ispressed will be set.
• Press and hold one of these buttons toincrease/decrease the speed in 1-mph or 1-km/h increments. Release the button whenyou have reached the desired speed.
NOTE
•
If one of the Adaptive Cruise Control but- tons is pressed for more than approxi-mately one minute, ACC will be deacti-vated. The engine must then be switchedoff and restarted to reset ACC.
• In some situations Adaptive Cruise Con- trol cannot be put in active mode.

Adaptive Cruise Control – setting time interval
Setting a time interval
Controls and display
Decrease/increase time interval
The set time interval to vehicles ahead can be increased by pressing
and decreased by
pressing
. The current time interval is shown
briefly in the display following adjustment. Different time intervals can be selected and are shown in the instrument panel
3
as 1–5 hori-
zontal bars. The greater the number of bars, the longer thetime interval. One bar repre-sents a time interval of approxi-
mately 1 second; 5 bars is approximately3 seconds.
To set/change a time interval:
• Press the
/ buttons (3).
At low speeds, when the distance to the vehicle ahead is short, ACC increases the time intervalslightly. In order to follow the vehicle ahead assmoothly as possible, ACC allows the time inter-val to vary considerably in certain situations.
WARNING
• Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.
