Emergency brake lights
The emergency brake lights are activated to warn following vehicles of hard braking. This function causes an additional taillight on each side of the vehicle to illuminate.
The emergency brake lights are activated in the event of hard braking or if the ABS system isactivated and the vehicle is traveling at a highspeed. After the driver decelerates to a low speed and then releases the brake, the brake lights resumetheir normal brightness.

Managing Cruise Control speedCruise Control (CC 29
) can be set to various
speeds.
Setting/changing set speed
Note: This illustration is general and details may vary depending on model.
For vehicles with only CC
–Change a set speed by pressing the (1)
or
(3) buttons briefly or by pressing and
holding them:
• Press briefly
: Press briefly: each press
changes the speed in +/- 1 mph (+/- 1 km/h) increments.
• Press
and hold: Release the button when
the set speed indicator (4) has moved tothe desired speed. •
The most recently set speed will be stored.
If speed is increased by depressing the accelera- tor pedal while pressing the
(1) button on
the steering wheel, the vehicle's speed when the button is pressed will be stored as the set speed. Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
For vehicles with both CC and ACC
–Change a set speed by pressing the (1)
or
(3) buttons briefly or by pressing and
holding them:
• Press briefly
: Press briefly: each press
changes the speed in +/- 5 mph (+/- 5 km/h) increments.
• Press
and hold: Release the button when
the set speed indicator (4) has moved tothe desired speed.
• The most recently set speed will be stored.
If speed is increased by depressing the accelera- tor pedal while pressing the
(1) button on
the steering wheel, the vehicle's speed when the button is pressed will be stored as the set speed. Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, will not affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applyingthe brakes. On downgrades, it can sometimes bedesirable to roll a bit faster and let speed bereduced instead by engine braking alone. Thedriver can temporarily disengage the Cruise Con-trol braking function. To disengage CC:
–Press the accelerator pedal about halfway down and then release it.
> Cruise Control will automatically disen- gage the automatic brake function and speed will only be reduced using theengine braking function.
How drive mode affects cruise controlThe way the cruise control maintains the vehicle'sspeed can vary depending on the selected drive mode 30
.

Cruise Control Eco Cruise
In the ECO drive mode, cruise control's accelera- tion and deceleration will be smoother than inother drive modes to help provide optimal fuelefficiency and reduced environmental impact.Because of this, the vehicle's actual speed maybe slightly above or below the set speed.
Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control's acceleration and deceleration will be faster andmore immediate than in other drive modes.

Deactivating and putting CruiseControl in standby mode
Cruise Control (CC 31
) can be temporarily put
into standby mode and then reactivated.
Deactivating and putting Cruise Control in standby mode
Note: This illustration is general and details may vary depending on model.
To put Cruise Control in standby mode:
–Press the button on the steering wheel
(2).
> The Cruise Control markings and symbols will change from WHITE to GRAY, indicat- ing that Cruise Control is temporarilydeactivated and the driver needs to con-trol the vehicle's speed.
Standby mode due to action by the driver
Cruise Control will be temporarily deactivated and put in standby mode if:
• the brakes are applied
• the gear selector is moved to
N
• the vehicle is driven faster than the setspeed for more than 1 minute
The driver must then control the vehicle's speed. Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic standby mode
Cruise Control will be temporarily deactivated and put in standby mode if:
• the wheels lose traction
• the engine speed (rpm) is too low/high
• the temperature in the brake systembecomes too high
• the vehicle's speed goes below 30 km/h(20 mph).
The driver must then control the vehicle's speed.

WARNING
•The Adaptive Cruise Control function is supplementary driver support intended tofacilitate driving and help make it safer –it cannot handle all situations in all traffic,weather and road conditions.
• The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion (see the link list at the end of thisarticle).
• Adaptive Cruise Control is not a substi-tute for the driver's attention and judg-ment. The driver is always responsible forensuring the vehicle is driven in a safemanner, at the appropriate speed, with anappropriate distance to other vehicles,and in accordance with current trafficrules and regulations.
NOTE
Depending on market, this function may be either Standard or Optional.
Adaptive Cruise Control regulates speed by accelerating and braking. It is normal for the brakes to emit a slight sound when they arebeing used to adjust speed. Adaptive Cruise Control always attempts to regu- late speed smoothly. The driver must apply thebrakes in situations requiring immediate braking.For example, when there are great differences inspeed between vehicles or if the vehicle aheadbrakes suddenly. Due to limitations in the radarsensor, braking may occur unexpectedly or not atall. Adaptive Cruise Control is designed to follow a vehicle ahead in the same lane and maintain atime interval to that vehicle set by the driver. If theradar sensor does not detect a vehicle ahead, itwill instead maintain the speed set by the driver.This will also happen if the speed of the vehicleahead exceeds the set speed for your vehicle.
• Adaptive Cruise Control can follow anothervehicle at speeds from a standstill up to200 km/h (125 mph).
WARNING
• Adaptive Cruise Control is not a collision avoidance system. The driver is alwaysresponsible and must intervene if the sys-tem fails to detect a vehicle ahead.
• Adaptive Cruise Control does not brakefor people or animals and does not brakefor small vehicles, such as bikes andmotorcycles. Similarly, it does not brakefor low trailers, oncoming, slow-moving orstationary vehicles and objects.
• Do not use Adaptive Cruise Control indemanding situations, such as in city traf-fic, at intersections, on slippery surfaces,with a lot of water or slush on the road, inheavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
CAUTION
Maintenance of Adaptive Cruise Control com- ponents may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.
