2008 VOLVO S80 brake

A faint sound from the parking brake's electric motor can be heard when the parking brake is being applied. This
sound can also be heard during the automatic function check of the parking brake.
The brake pedal will move slightly when the electric parking brake is applied or released.
Low battery voltage
If the battery voltage is too low, the parking brake cannot be applied or released. Connect an auxiliary battery if the
battery voltage is too low, see page 109
.
1The electric parking brake is available as an option on certain models.
Applying the electric parking brake
1. Press firmly on the brake pedal.
2. Press the control.
3. Release the brake pedal and ensure that the vehicle is at a standstill.
4. When the vehicle is parked, the gear selector must be in position P .
The
symbol in the instrument panel flashes while the parking bake is being applied, and glows steadily when
the parking brake has been fully applied.
NOTE
In an emergency the parking brake can be applied when the vehicle is moving by holding in the control. Braking
will be interrupted when the accelerator pedal is depressed or the control is released.
An audible signal will sound during this procedure if the vehicle is moving at speeds above 6 mph (10 km/h).
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 electric parking brake

Manual release
1. Fasten the seat belt.
2. Insert the remote key in the ignition slot.
3. Press firmly on the brake pedal.
4. Pull the parking brake control.
Vehicles with Keyless drive (option)
1. Press the START/STOP ENGINE button.
2. Press firmly on the brake pedal.
3. Pull the parking brake control.
Automatic release
1. Start the engine.
2. Fasten the seat belt.
NOTE
For safety reasons, the parking brake is only released automatically if the engine is running and the driver is
wearing a seat belt.
The electric parking brake will be released immediately when the accelerator pedal is pressed and the gear selector
is in position D or P.
3. Move the gear selector to position D or R and press the accelerator pedal. The parking brake will release when the
vehicle begins to move.
Heavy load uphill
A heavy load, such as a trailer, can cause the vehicle to roll backward when the parking brake is released
automatically on a steep incline. To help avoid this:
1. Keep the electric parking brake lever pushed in with the left hand while shifting into Drive with the right.
2. While pressing the throttle pedal to pull away, release the parking brake lever only after the vehicle begins to move.

If the symbol
appears alone, it may appear as follows:
If the symbol flashes, this indicates that the stability system is actively functioning to help counteract wheel spin
and/or a skid.
If the symbol remains on for approximately 2 seconds after the engine has been started, this indicates that the system
is performing a self -diagnostic test.
WARNING
The stability system is intended to help improve driving safety. It supplements, but can never replace, the driver's
judgment and responsibility when operating the vehicle. Speed and driving style should always be adapted to traffic
and road conditions.

Adjusting the set speed
After a speed has been set, it can be increased or decreased by using the
or buttons.
Press and hold down or until the vehicle reaches the desired 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 vehicle speed by
approximately 1 mph (1.6 km/h).
NOTE
A temporary increase in speed by pressing the accelerator pedal, for less than 1 minute (e.g. when passing another
car), does not affect the current cruise control setting. The vehicle will automatically return to the previously set
speed when the accelerator pedal is released.
If one of the cruise control buttons is kept depressed for more than approx. 1 minute cruise control is disengaged.
The engine must then be switched off in order to reset cruise control.
Automatic deactivation
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 using the accelerator pedal for more than 1 minute.
The currently set speed will be saved in the system's memory.

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.
