WARNING
•If both symbols illuminate at the same time and the brake level is below the
MIN
mark in the reservoir or if a brake system- related message is shown in the instru-ment panel: DO NOT DRIVE. Have thevehicle towed to a trained and qualifiedVolvo service technician and have thebrake system inspected.
• If both symbols illuminate at the sametime and the brake level is normal (notbelow the MIN mark in the reservoir) or ifa brake system-related message isshown in the instrument panel: drive thevehicle carefully to an authorized Volvoworkshop and have the brake systeminspected by a trained and qualified Volvoservice technician.

Brake Assist System
The brake enhancing system, Brake Assist
System (BAS), helps increase braking force andthereby reduce braking distance.
The system monitors the driver's braking habits and increases braking force when necessary.Braking force can be increased up to the point atwhich the ABS intervenes. The function is deacti-vated when pressure on the brake pedal isdecreased.
NOTE
When BAS is activated, the brake pedal will go down slightly more than usual. Press(hold) down the brake pedal as long as nec-essary. When the brake pedal is released, all braking ceases.

• Brakes (p. 409)
Braking on wet roads
Prolonged driving in heavy rain without braking may cause braking effect to be slightly delayedthe first time the brakes are applied.
This may also occur after washing the vehicle. It will then be necessary to apply greater pressureto the brake pedal. You should therefore maintaina greater distance to the vehicle ahead. Firmly apply the brakes after washing the vehicle or driving on wet roads. This helps warm up thebrake discs, enabling them to dry more quicklyand protecting them against corrosion. Considerthe current traffic situation when braking.

Braking on salted roads When driving on salted roads, a layer of salt may form on the brake discs and brake pads.
This could increase stopping distance. Maintain an extra large safety distance to the vehicleahead. Make sure to also:
• Apply the brakes from time to time to helpremove salt. Make sure braking does notpose a risk to any other road users.
• Gently apply the brakes when you have fin-ished driving and before driving again.

Maintenance of the brake system
Regularly check the brake system components for wear.
To keep the vehicle as safe and reliable as possi- ble, follow the Volvo service schedule specified inthe Warranty and Maintenance Records Informa-tion booklet. New and replaced brake pads andbrake discs do not provide optimal braking effectuntil they are "broken in" by driving a few hun-dred kilometers (miles). Compensate for thereduced braking effect by applying greater pres-sure to the brake pedal. Volvo recommends onlyusing brake pads approved for your Volvo.
CAUTION
The brake system's components should be regularly checked for wear. Contact a workshop for advice on how to do this or let a workshop perform the inspection- an authorized Volvo workshop is recom-mended.

• Brakes (p. 409)
Parking brake The parking brake helps keep the vehicle sta- tionary by mechanically locking two wheels.
The parking brake controls are located in the tunnel console between the seats.
When the electric parking brake is being applied, a faint sound can be heard from the brake's elec-tric motor. This sound can also be heard duringthe automatic function check of the parkingbrake. If the vehicle is stationary when the parking brake is applied, it will only be applied to the rearwheels. If it is applied while the vehicle is moving,the normal brakes will be used on all four wheels.Braking will be transferred to only the rearwheels when the vehicle is almost stopped.

Auto-hold brakes
With the Auto-hold brake function, the driver can release the brake pedal and the brakes willremain applied, for example, when the vehiclehas stopped at a traffic light or intersection.
When the vehicle stops, the brakes are activated automatically. The function can use either thenormal brakes or the parking brakes to keep thevehicle stationary and works on flat surfaces orhills. When driving off, the brakes will be automat-ically released if the driver's seat belt is buckled.
NOTE
When braking to a stop on an uphill or down- hill gradient, depress the brake pedal withslightly more force than usual before releas-ing to ensure that the vehicle cannot move atall.
The parking brake is activated if: • the vehicle is switched off
• the driver's door is opened
• the driver's seat belt is removed
• the vehicle has been stationary for a pro- longed period of time (5-10 minutes)
