2008 VOLVO S80 warning light

Introduction
HomeLink1 is a system that can be programmed to learn the codes of three different remote controlled-devices (for
example, a garage door opener, remote lighting, entry gate). HomeLink's sun visor-mounted transceiver, powered by
your car's electrical system, may then be used in place of your handheld remote controls. The HomeLink transceiver
consists of three programmable buttons and an indicator light.

NOTE
For your security, the HomeLink Universal Transceiver is designed to not function if you lock your car from the
outside.
Retain the original transmitter(s) for future programming procedures (for example, if you purchase a new vehicle).
For your own security, erase all programmed buttons on the HomeLink Universal Transceiver when you sell your
vehicle.
Metallic sun protection films should not be used on any windows in a vehicle equipped with HomeLink Universal
Transceiver. This could interfere with the transceivers function.
Operating the HomeLink Universal Transceiver
Once programmed, the HomeLink Universal Transceiver can be used in place of your handheld transmitters.
NOTE
The HomeLink universal transceiver will function for 30 minutes after the driver's door has been opened without
switching on the vehicle's ignition.
Press the programmed HomeLink button to activate the garage door, driveway gate, security lightning, home security
system etc.
Your original hand -held transmitters may, of course, be used at any time.
WARNING
If you use HomeLink to open a garage door or gate, be sure no one is near the gate or door while it is in motion.
Do not use the HomeLink Universal Transceiver with any garage door opener that lacks safety "stop" and
"reverse" features as required by federal safety standards. (This includes any garage door opener model manufactured
before April 1, 1982). A garage door opener that cannot "detect" an object, signalling the door to "stop" and
"reverse" does not meet current federal safety standards. Using a garage door opener without these features increases
the risk of serious injury or death. For more information on this matter, call toll-free 1-800-355-3515. (Internet:

112 03 Your driving environment
Transmission
All Wheel Drive - AWD1
Your Volvo can be equipped with permanent All Wheel Drive, which means that power is distributed automatically
between the front and rear wheels. Under normal driving conditions, most of the engine's power is directed to the front
wheels. However, if there is any tendency for the front wheels to spin, an electronically controlled coupling distributes
power to the wheels that have the best traction.
1Standard on certain models.
113 03 Your driving environment
Brakes
Brake system
The brake system is a hydraulic system consisting of two separate brake circuits. If a problem should occur in one of
these circuits, it is still possible to stop the vehicle with the other brake circuit.
If the brake pedal must be depressed farther than normal and requires greater foot pressure, the stopping distance will
be longer.
A warning light in the instrument panel will light up to warn the driver that a fault has occurred.
If this light comes on while driving or braking, stop immediately and check the brake fluid level in the reservoir.

The parking brake pedal is located under the dashboard, to the left of the brake pedal. When the brake is applied, an
indicator light illuminates in the instrument panel.
NOTE
The indicator light will light up even if the parking brake has only been partially applied.
Applying the parking brake
1. Press firmly on the brake pedal.
2. Press down pedal 1 firmly to its full extent.
3. Release the brake pedal and ensure that the vehicle is at a standstill.
4. If the vehicle rolls, the parking brake pedal must be pushed down more firmly.
5. When parking a vehicle always put the gear selector in P .
WARNING
Press down the parking brake pedal firmly to its full extent.
Parking on a hill
If the vehicle is pointing uphill, turn the front wheels so that they point away from the curb.
If the vehicle is pointing downhill, turn the front wheels so that they point toward the curb.
Releasing the parking brake
1. Press firmly on the brake pedal.

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
to remain approximately 2 seconds behind the vehicle ahead).

157 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 160
.
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 166
.
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 to alert the driver to react.
NOTE

Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if the driver is not looking straight
ahead may make the visual warning signal in the windshield difficult to see.
WARNING
Cruise control only warns of vehicles detected by the radar sensor, see page 160
. In some cases there may be no
warning or the warning may be delayed. The driver should always apply the brakes when necessary.

Engaging the cruise control function
Before ACC can be used, it must first be put in standby mode.
To do so, press
. The symbol illuminates in the display and (---) indicate that ACC is in standby mode.
Setting a speed
Use the
or buttons to store (set) the vehicle's current speed. The set speed, for example 55 mph , is shown in
the display.
NOTE
Adaptive cruise control cannot be engaged at speeds below 20 mph (30 km/h).

The "car" symbol illuminates on the left side of the display when the radar sensor detects another
vehicle ahead. The distance to a vehicle ahead is only regulated when this symbol is illuminated.
Adjusting the set speed
After a speed has been set, it can be increased or decreased by using the
or buttons.
When the system is in active mode, the
button has the same function as , but results in a smaller increase in
speed.
NOTE
If one of the adaptive cruise control buttons is pressed for more than approximately one minute, ACC will be
deactivated. The engine must then be switched off and restarted to reset ACC.
In some situations cruise control cannot be activated. Cruise Control Unavailable is shown in the display, see page
166.
Setting a time interval
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 and are shown in the display as 1-5 horizontal bars. The
greater the number of bars, the longer the time interval.
At low speeds, when the distance to the vehicle ahead is short, ACC increases the time interval slightly.
In order to follow the vehicle ahead as smoothly as possible, ACC allows the time
159 04 Comfort and driving pleasure
Adaptive Cruise Control-ACC
interval 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 limited reaction time if an unexpected situation occurs in traffic.
The number of bars indicating the selected time interval are shown while the setting is being made and for several
seconds afterward. A smaller version of the symbol is then shown to the right in the display. The same symbol is also
displayed when Distance Alert is activated, see page 163
.
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.
