Collision Warning with Auto-brake (option)
WARNING
The camera has the same limitations as the human eye. In other words, its "vision is impaired" by adverse weather
conditions such as heavy snowfall, dense fog, etc. These conditions may reduce the function of systems that depend
on the camera or cause these systems to temporarily stop functioning.
Never place any objects, decals, etc., on the windshield in front of the camera. This could reduce or block the
camera's function, and could cause one or more of the systems that utilize the camera to stop functioning.
Strong sunlight, reflections from the road surface, a dirty road surface, or unclear lane marker lines may
drastically reduce the camera's capacity to detect the side of a lane or another vehicle.
Fault tracing and actions
If the message Camera blocked See manual is displayed, this means that the camera is obscured and cannot detect
vehicle or road marker lines in front of the vehicle.
This, in turn, means that Collision Warning with Auto-brake, Lane Departure Warning, and Driver Alert Control will
not have full functionality.
The table lists possible causes for this message being displayed, and suitable actions.

Symbols and messages in the display

This function is intended to alert the driver if his/her driving becomes erratic, such as if the driver is distracted or
fatigued.
A camera monitors the painted lines marking the lane in which the vehicle is traveling and compares the direction of
the road with the driver's movements of the steering wheel. The driver is alerted if the vehicle does not follow the lane
smoothly.
NOTE
The camera has certain limitations, see page 168
.
DAC is designed to help detect a slowly changing driving pattern. It is primarily intended to be used on main roads
and is not meant for use in city traffic.
WARNING
DAC is not intended to extend the duration of driving. Always plan breaks at regular intervals to help remain
alert.
In certain cases, fatigue may not affect the driver's behavior. In situations of this type, no warning will be
provided. Therefore, it is important to take breaks at regular intervals, regardless of whether or not DAC has given a
warning
Limitations
In certain situations, DAC may provide warnings even if the driver's driving pattern has not become erratic.

The function is activated when the vehicle exceeds a speed of 40 mph (65 km/h). The display will
show level markings of 1-5 bars, where a low number of bars indicates erratic driving. A high number
of bars indicates stable driving.
If the vehicle is being driven erratically, the driver will be alerted by an audible signal and the message Driver Alert,
Time for a break is displayed. The warning will be repeated after a short time if the driving pattern remains the same.
WARNING
An alert should be taken seriously since it is sometimes difficult for a driver to realize that he/she is fatigued.
In the event of a warning or if the driver feels fatigued, stop as soon as possible in a safe place and rest.

Lane Departure Warning (LDW)-general information
This function is designed to help reduce the risk of accidents in situations where the vehicle leaves its lane and there is
a risk of driving off the road or into the opposite lane.
LDW consists of a camera that monitors the lane's side marker lines. The driver is alerted by an audible signal if the
vehicle crosses a side marker line or the road's center dividing line.
Operation and function
LDW can be switched on or off by pressing the button on the center console. A light in the button illuminates when the
function is on.
The trip computer display shows Lane Depart Warn Unavailable when the function is in standby mode.
When LDW is in standby mode, the function is activated automatically after the camera has monitored the road's side
marker lines and the vehicle's speed exceeds 40 mph (65 km/h). Lane Depart Warn Available will be displayed.
If the camera can no longer monitor the road's side marker lines, or if the vehicle's speed falls below 37 mph (60
km/h), LDW will return to standby mode and Lane Depart Warn Unavailable will be displayed.
If the vehicle unexpectedly crosses the lane's left or right side marker lines, the driver will be alerted by an audible
signal.
No warning signal will be given in the following situations:
The turn signal is being used
The driver's foot is on the brake pedal1

The throttle pedal is pressed quickly
If the steering wheel is moved quickly
In sharp turns that cause the vehicle's body to sway.
The camera also has certain limitations. See page 168
for information.
WARNING
The driver will only be warned once for each time the wheels cross a marker line. No alarm will be given if a marker
line is between the wheels.

Driver Alert System -option
Introduction
The park assist system is designed to assist you when driving into parking spaces, garages, etc.

This system is available in the rear bumper only, or in both the front and rear bumpers.
Park assist utilizes four ultrasound sensors in the bumper(s) to measure the distance to a vehicle, object, or a person
who may be close to the front or rear of your vehicle. An audible signal and symbols in the audio system's display
indicate the distance to the object.
WARNING
Park Assist is an information system, NOT a safety system. This system is designed to be a supplementary aid when
parking the vehicle. It is not, however, intended to replace the driver's attention and judgement.
Function
Park assist is activated automatically when the vehicle is started. The indicator light in the button in the center console
illuminates when the system is on.
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.
Activating/deactivating
The system is activated automatically when the vehicle is started.
Press the Park assist button on the center console to temporarily deactivate the system(s). The indicator light in the
button will go out when the system has been deactivated.
Park assist will be automatically reactivated the next time the engine is started, or if the button is pressed (the
indicator light in the button will illuminate).
NOTE
Front park assist is disengaged automatically when the parking brake is applied.
If the vehicle is equipped with front and rear park assist, both systems will be deactivated by pressing the button.

Signals from the park assist system

Visual indicator
The audio system's display gives an overview of the vehicle's position in relation to a detected object.
The markers in the display indicate that one or more of the four sensors has detected an object. The greater the number
of markers, the closer the vehicle is to the object.
Display in a vehicle with rear park assist only. Here, an object has been detected by both of the right rear sensors.
Display in a vehicle with both front and rear park assist. The solid marker in this example indicates that an object is
closer than approximately 1 foot (30 cm) to the right front sensor.
Display in a vehicle with both front and rear park assist. Reverse gear is selected and no objects have been detected
in front of or behind the vehicle.
Audible signal
The Park Assist system uses an intermittent tone that pulses faster as you come close to an object, and becomes
constant when you are within approximately 1 ft (30 cm) of an object in front of or behind the vehicle (example 2 in
the illustration). If there are objects within this distance both behind and in front of the vehicle, the tone alternates
between front and rear speakers.
If the volume of another source from the audio system is high, this will be automatically lowered.
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The audible signal comes from the rear
speakers.
The system must be deactivated when towing a trailer, carrying bicycles in a rear-mounted carrier, etc, which could
trigger the rear park assist system's sensors.
NOTE
Rear park assist is deactivated automatically when towing a trailer if Volvo genuine trailer wiring is used.

178 04 Comfort and driving pleasure
Park assist (option)
Front park assist
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audible signal comes from the audio
system's front speakers.
It may not be possible to combine auxiliary headlights and front park assist since these lights could trigger the system's
sensors.
Faults in the system
If the information symbol illuminates and Park Assist syst Service required is shown on the information display, this
indicates that the system is not functioning properly and has been disengaged. Consult a trained and qualified Volvo
service technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning signals that can be caused by external
sound sources that use the same ultrasound frequencies as the system. This may include such things as the horns of
other vehicles, wet tires on asphalt, pneumatic brakes, motorcycle exhaust pipes, etc. This does not indicate a fault in
the system.
Cleaning the sensors
The sensors must be cleaned regularly to ensure that they work properly. Clean them with water and a suitable car
washing detergent.
Ice and snow covering the sensors may cause incorrect warning signals.
