Anti-lock braking system (ABS) The ABS system helps to improve vehicle con- trol (stopping and steering) during severe brak-ing conditions by limiting brake lockup.
When the system "senses" impending lockup, braking pressure is automatically modulated inorder to help prevent lockup that could lead to askid. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.

Brake lights The brake lights come on automatically when the brakes are applied.
Adaptive brake lights
The adaptive brake lights activate in the event of sudden braking or if the ABS system is activated.This function causes an additional taillight oneach side of the vehicle to illuminate to help alertvehicles traveling behind. The adaptive brake lights activate if:
• The ABS system activates for more than approximately a half second
• In the event of sudden braking while thevehicle is moving at speeds above approxi-mately 6 mph (10 km/h).
When the vehicle has come to a stop, the brakelights and additional taillights remain on for aslong as the brake pedal is depressed or untilbraking force on the vehicle is reduced.

Emergency Brake Assistance (EBA)
EBA is designed to provide full brake effect immediately in the event of sudden, hard brak-ing.
Emergency Brake AssistanceThe EBA system is activated by the speed with which the brake pedal is depressed. When the EBA system is activated, the brake pedal will go down and pressure in the brake sys-tem immediately increases to the maximum level.Maintain full pressure on the brake pedal in orderto utilize the system completely. EBA is automati-cally deactivated when the brake pedal isreleased.

NOTE
•When the EBA system is activated, the brake pedal will go down and pressure inthe brake system immediately increasesto the maximum level. You must maintainfull pressure on the brake pedal in orderto utilize the system completely. Therewill be no braking effect if the pedal isreleased. EBA is automatically deacti-vated when the brake pedal is released.
• When the vehicle has been parked forsome time, the brake pedal may sinkmore than usual when the engine isstarted. This is normal and the pedal willreturn to its usual position when it isreleased.

NOTE
•
A faint sound from the parking brake's electric motor can be heard when theparking brake is being applied. Thissound can also be heard during the auto-matic function check of the parkingbrake.
• The brake pedal will move slightly whenthe electric parking brake is applied orreleased.
Low battery voltageIf the battery voltage is too low, the parking brake cannot be applied or released.
Connect
an auxiliary battery if the battery voltage is toolow, see Jump starting (p. 261).
Parking on a hill
• If the vehicle is pointing uphill, turn the frontwheels so that they point away from the curb.
• If the vehicle is pointing downhill, turn thefront wheels so that they point toward thecurb.
The parking brake should also be applied.

Applying the electric parking brake
Parking brake control
1. Press firmly on the brake pedal. 2.Push the control. >
The
symbol in the instrument
panel flashes while the parking brake is being applied and glows steadily when theparking brake has been fully applied.
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.
NOTE
• In an emergency the parking brake can be applied when the vehicle is moving byholding in the control. Braking will beinterrupted when the accelerator pedal isdepressed or the control is released.
• An audible signal will sound during thisprocedure if the vehicle is moving atspeeds above 6 mph (10 km/h).

Automatic release
1. Start the engine.
NOTE
•For safety reasons, the parking brake is only released automatically if the engine isrunning and the driver is wearing a seatbelt.
• The electric parking brake will be releasedimmediately when the accelerator pedal ispressed and the gear selector is in posi- tion
D or R.
2. Fasten the seat belt. 3.
Move the gear selector to position D or R
and press the accelerator pedal. The parking brake will release when the vehicle begins tomove.
Heavy load uphill
A heavy load, such as a trailer, can cause the vehicle to roll backward when the parking brakeis released automatically on a steep incline. Tohelp 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 accelerator pedal to pull away, release the parking brake lever onlyafter the vehicle begins to move.

A flashing symbol indicates that the parking brake is being applied. If the symbol flashes in any other situation then this means that a fault has arisen. Read the message on the information display.
-Park brake not fully releasedA fault is preventing the parking brake from being released. Try to apply the parking brake and release it several times. If the problem persists, contact an authorized Volvo workshop. If you drive off with this error message showing, a warningsignal sounds.

-Parking brake Service requiredA fault has occurred. Try to apply and release. Contact a Volvo workshop if the fault remains
WARNING
If the vehicle must be parked before the fault has been corrected, always put the gear selector in P and turn the wheels so that they
point away from the curb if the vehicle is pointing uphill or toward the curb if it is point-ing downhill.

WARNING
•Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation, or"blow-out," with unexpected loss of vehi-cle control and increased risk of injury.
• Under-inflated tires reduce the load car-rying capacity of your vehicle.
When weather temperature changes occur, tire inflation pressures also change. A 10-degreetemperature drop causes a corresponding dropof 1 psi (7 kPa) in inflation pressure. Check yourtire pressures frequently and adjust them to theproper pressure, which can be found on the vehi-cle's tire information placard or certification label.

Tire inflation – checking pressure
Inflation pressure should be checked when the tires are cold.
Cold tires
The tires are considered to be cold when they have the same temperature as the sur-rounding (ambient) air. This temperature is normally reached after the vehicle has been parked for at least 3 hours. After driving a distance of approximately 1 mile (1.6 km), the tires are considered to be hot. If youhave to drive farther than this distance to pumpyour tire(s), check and record the tire pressurefirst and add the appropriate air pressure whenyou get to the pump. If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tiresare hot from driving and it is normal for pressuresto increase above recommended cold pressures.A hot tire at or below recommended cold inflationpressure could be significantly under-inflated.
To check inflation pressure:
1. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve.
2. Add air to reach the recommended air pres- sure. 3. Replace the valve cap.
CAUTION
•
After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
4. Visually inspect the tires to make sure there
are no nails or other objects embedded that could puncture the tire and cause an air leak.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregulari-ties.
6. Repeat this procedure for each tire, including the spare 3
.
NOTE
• If you overfill the tire, release air by push- ing on the metal stem in the center of thevalve. Then recheck the pressure withyour tire gauge.
• Some spare tires (available as an acces-sory) require higher inflation pressurethan the other tires. Consult the tire infla-
