Adaptive Cruise Control-ACC
Introduction
Adaptive Cruise Control (ACC) is an optional system designed to assist the driver by maintaining a set speed or a set
distance to the vehicle ahead. It is primarily intended for use on long straight roads in steady traffic, such as on
highways and other main roads.
WARNING
Do not use the adaptive cruise control system in demanding driving conditions such as city traffic, winding roads,
at intersections, on slippery surfaces, in poor visibility, heavy rain, etc.
Maintenance of cruise control components must only be performed by an authorized Volvo workshop.
WARNING
Adaptive cruise control cannot cover all driving situations and traffic, weather and road conditions. The Function
section provides information about limitations that the driver must be aware of before using the adaptive cruise
control.
This system is designed to be a supplementary driving aid. It is not, however, intended to replace the driver's
attention and judgement. The driver is responsible for maintaining a safe distance and speed and must intervene if
adaptive cruise control does not maintain a suitable speed or suitable distance.
Function
Warning light, braking by driver required
Controls
Radar sensor in front grille
Adaptive cruise control consists of:
A cruise control system to maintain a set speed
A system to maintain a set distance to the vehicle ahead (expressed as a time interval. For example, you can choose
ProCarManuals.com

to remain approximately 2 seconds behind the vehicle ahead).
145 04 Comfort and driving pleasure
Adaptive Cruise Control-ACC
WARNING
Adaptive cruise control is not a collision avoidance system. The driver is always responsible for applying the
brakes if the system does not detect another vehicle.
Adaptive cruise control does not react to slow moving or stationary vehicles.
The distance to the vehicle ahead (in the same lane) is measured by a radar sensor. Your vehicle's speed is regulated by
acceleration and braking. The brakes may emit a sound when they are being modulated by the adaptive cruise control
system. This is normal.
WARNING
The brake pedal moves when the adaptive cruise control system modulates the brakes. Do not rest your foot under
the brake pedal.
The adaptive cruise control system is designed to follow the vehicle ahead of you in the same lane, at a set time
interval.
If the radar sensor has not detected a vehicle ahead, the system will then attempt to maintain the set speed. This is also
the case if the speed of the vehicle ahead exceeds the speed that you have set.
The adaptive cruise control system is designed to smoothly regulate speed. However, the driver must apply the brakes
in situations that require immediate braking. This applies when there are great differences in speed between vehicles,
or if the vehicle ahead brakes suddenly.
WARNING
Due to limitations in the radar sensor, braking may occur unexpectedly or not at all, see page 146
.
Adaptive cruise control can only be activated at speeds above 20 mph (30 km/h). If speed falls below 20 mph (30
km/h) or if engine speed (rpm) becomes too low, adaptive cruise control disengages and will no longer modulate the
brakes. In situations when adaptive cruise control cannot be activated Cruise Control Unavailable is shown in the
display, see page 149
.
WARNING
When adaptive cruise control disengages, the brakes will not be modulated automatically. The driver must assume
full control over the vehicle.
Warning light -driver braking required
Adaptive cruise control has a braking capacity that is equivalent to approximately 30% of the vehicle's total braking
capacity. In situations requiring more brake force than ACC can provide, if the driver does not apply the brakes, an
audible signal will sound and a red warning light will illuminate in the windshield.
ProCarManuals.com

NOTE
The red warning light may be difficult to see in strong sunlight or when sunglasses are being worn.
WARNING
Cruise control only warns of vehicles detected by the radar sensor, see page 146
. In some cases there may be no
warning or the warning may be delayed. The driver should always apply the brakes when necessary.
Automatic deactivation
Adaptive cruise control is linked to other systems such as the stability and traction control system (DSTC). If any of
these systems are not functioning properly, adaptive cruise control is automatically deactivated.
In the event of automatic deactivation a signal will sound and the message Cruise Control Canceled is shown in the
display. The
146 04 Comfort and driving pleasure
Adaptive Cruise Control-ACC
driver must then intervene and adapt the vehicle's speed to the surrounding traffic. Automatic deactivation may be
caused if:
the vehicle's speed falls below 20 mph (30 km/h)
the wheels lose traction or if the anti-lock brake system is activated
brake temperature is high
engine speed (rpm) is too low
the radar sensor is obstructed by, for example, wet snow or rain.
The radar sensor and its limitations
The radar sensor is used both by the adaptive cruise control and the collision warning system. It is designed to detect
vehicles or larger vehicles driving in the same direction as your vehicle. The radar sensor does not detect pedestrians,
or oncoming, slow or stationary vehicles and objects. Warnings are not given and the brakes are not applied in such
cases.
WARNING
Accessories or other objects must not be installed in front of the grille.
Modification of the radar sensor could make its use illegal.
The radar sensor's capacity to detect vehicles ahead is impeded:
if the radar sensor is obstructed and cannot detect other vehicles, for example in heavy rain, or if snow or other
objects are obscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor clean.
ProCarManuals.com

if the speed of vehicles ahead is significantly different from your own speed.
The radar sensor has a limited field of vision. In some situations it may detect a vehicle other than the one expected or
not detect vehicles at all.
In certain situations, the radar sensor cannot detect vehicles at close quarters, for example a vehicle that suddenly
enters the lanes between your vehicle and the one that the system has already detected.
Small vehicles, such as motorcycles, or vehicles not driving in the center of the lane may remain undetected.

Adaptive cruise control is disengaged (goes into standby mode):
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 using the accelerator pedal for more than 1 minute.
NOTE
If the accelerator pedal is depressed for a short period, such as when passing another vehicle, adaptive cruise control
is temporarily disengaged and re-engages when the accelerator pedal is released.
When ACC is disengaged, the driver must assume full control of the vehicle.
Engaging the cruise control function
Before ACC can be used, it must first be put in standby mode.
To do so, press

Press and hold down or to increase or decrease the set speed. This will become the set speed when the button
is released.
Press or for approximately a half second and release the button to increase or decrease the set speed by
approximately 5 mph (8 km/h)
When the system is in active mode, the button has the same function as , but results in a smaller increase in
speed.
NOTE
If adaptive cruise control does not react to activation, this may be because the set time interval to the closest
vehicle prevents an increase in speed.
In some situations cruise control cannot be activated. Cruise Control Unavailable is shown in the display, see page
149.
Setting a time interval
ProCarManuals.com

The set time interval to vehicles ahead is increased with and decreased with . The current time interval is
shown briefly in the display following adjustment.
Five different time intervals can be selected.
A longer time interval results in smoother speed control. The recommended time interval is three to five.
Time intervals one and two are primarily intended for driving in queues in heavy traffic, in which case you must
intervene more often.
WARNING
Only use the time interval that is permitted by local traffic regulations.
Deactivating and resuming settings
Cruise control is deactivated, either with a short press on
, or by action taken by the driver, such as braking, etc.
The set speed is then shown in parentheses. Speed and time interval are resumed with one press on
.
WARNING
There may be a significant increase in speed after the
button has been pressed.
A short press on
in standby mode or a long press in active mode deactivates cruise control. The set speed is then
cleared and cannot be resumed.

Collision warning system (option)
Introduction
The Collision Warning with Brake Support, (CW) is designed to assist the driver by warning of collision risk. The
brake support helps reduce the collision speed.
WARNING
The collision warning system does not work in all driving situations and traffic, weather and road conditions.
The system does not react to slow moving or stationary vehicles, or vehicles that are not traveling in the same
direction as your vehicle.
Warnings are only provided when the risk of collision is high. The Function section provides information about
limitations that the driver must be aware of before use.
The collision warning system's brake support can only reduce the speed at which a collision occurs if the driver
applies the vehicle's brakes.
WARNING
Never wait for a collision warning. This system is designed to be a supplementary driving aid. It is not, however,
intended to replace the driver's attention and judgement. The driver is responsible for maintaining a safe distance and
speed, even when the collision warning system is in use.
Maintenance of the collision warning system components must only be performed by a trained and qualified
Volvo technician.
Function
ProCarManuals.com

Visual warning signal, collision risk
Sensor
The radar sensor detects vehicles ahead that are moving in the same direction as your vehicle. In the event of a
collision risk, you will be alerted by a red warning light and an audible warning signal.
If the risk of collision increases after the warning, brake support is activated.
The brake support prepares the brake system for rapid braking and the brakes are applied gently, which may be
noticeable. If the brake pedal is depressed quickly then braking is implemented with full brake function, even if the
force on the pedal is light.
151 04 Comfort and driving pleasure
Collision warning system (option)
The collision warning system is active at speeds above approximately 5 mph (7 km/h).
Limitations
The visual warning signal may be difficult to see in strong sunlight or when sunglasses are being worn. For this reason
always activate the audible warning signal in such conditions.
NOTE
The visual warning signal may be temporarily disengaged in the event of high passenger compartment temperature
due to strong sunlight, etc. If this occurs, the audible warning signal will be used, even if it has been deactivated in
the menu system.
Warnings may not appear if the distance to the vehicle ahead is very small or if steering wheel and pedal movements
are large, for example, due to a very active driving style.
The collision warning system uses the same radar sensors as adaptive cruise control. For more information on the radar
sensor and its limitations, see page 146
.
WARNING
In certain situations, the system cannot provide warnings, the warning may be delayed, or false warnings may be
given if traffic conditions make it impossible for the radar sensor to detect the vehicle ahead.
If no warning is given, no brake support is provided.
ProCarManuals.com

A delayed warning means that brake support will also be delayed.
The false warnings may be in the form of both audio and visual signals.
NOTE
The number of false warnings can be limited by reducing the warning distance. See the section "Set warning
distance."
Operation
Some settings are controlled from the center console via a menu system. For information on how the menu system is
used, see page 114
.
NOTE
The following settings apply to the collision warning system only and do not affect brake support.

Park assist (option)
Introduction
The park assist system(s) are designed to assist you when driving into parking spaces, garages, etc. They utilize
ultrasound sensors located in the bumpers to measure the distance to a vehicle or other object, or a person who may be
close to the front or rear of the vehicle.
WARNING
These systems are designed to be a supplementary aid when parking the vehicle. They are not, however, intended to
replace the driver's attention and judgement.
Function
The system is activated automatically when the vehicle is started. The indicator light in the button in the center console
illuminates. The text Park Assist ON is shown in the center console display if reverse gear is selected or if the front
sensors detect an object.
The front park assist system is active from the time the engine is started until the vehicle exceeds a speed of
approximately 10 mph (15 km/h). It is also active when the vehicle is backing up.
Rear park assist is active when the engine is running and reverse gear has been selected.
An intermittent audio signal becomes audible when your vehicle approaches an object. The frequency of the signal
increases as you come closer to the object in front of or behind the vehicle. If the volume of another audio source from
the audio system is high, this will be automatically lowered.
The tone becomes constant at a distance of approximately 1 ft (30 cm). If there are objects within this distance both
behind and in front of the vehicle, the signal alternates between front and rear speakers.
