Brake functions
The vehicle's brakes are used to reduce speedor prevent the vehicle from rolling.
In addition to the wheel brakes and parkingbrakes, the vehicle is also equipped with a num-ber of automatic brake assist functions. Thesesystems help the driver by e.g. keeping the vehi-cle stationary when the brake pedal is notdepressed (e.g. at a traffic light or intersection) orwhen starting up a hill.
Depending on how the vehicle is equipped, thefollowing brake assist functions may be included:
Auto-hold brake function at a standstill (AutoHold)
Hill Start Assist (Hill Start Assist)
Braking assist after a collision

Brakes
The brake pedal is used to apply the vehicle'sregular brakes, which are part of the brake sys-tem.
The vehicle is equipped with two brake circuits. Ifone brake circuit is damaged, the brake pedal willgo down further when depressed. More pressurewill then be required from the driver for normalbraking effect.
WARNING
The power brakes only work when the electricmotor or combustion engine is running.
If the brake pedal is used when the engine isswitched off, greater pressure must be applied tobrake the vehicle.
In very hilly areas or when driving with a heavyload, gear position B can be used to augment thebrakes with engine braking.
Anti-lock brakes
The vehicle is equipped with an Anti-lock Braking
System (ABS2), which helps prevent the wheelsfrom locking and helps maintain steering controlwhen braking. Vibrations may be felt from thebrake pedal when ABS is operating, which is nor-mal.
After the vehicle is started, a brief test of theABS system is automatically performed when thedriver releases the brake pedal. An additionalautomatic test of the system may be performedwhen the vehicle is traveling at a low speed. Dur-ing the test, the brake pedal may feel as though itis pulsating.
Light braking charges the hybrid battery
When the brakes are applied lightly, the electricmotor braking function is used. This converts thevehicle's kinetic energy into electrical energy,which is used to charge the hybrid battery. Whenthe battery is being charged with the electricmotor braking function, this will be indicated inthe instrument panel.
When the battery is being charged with the electricmotor braking function, this will be indicated in theinstrument panel.
This function is active at speeds in the range of150-5 km/h (93-3 mph). When braking atspeeds outside of this range, or during harderbraking, the hydraulic braking system is used toaugment braking. This is indicated in the instru-ment panel with the pointer down in the red area.

WARNING
If the warning symbols for both brake faultand ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is normalwhen this occurs, drive carefully to thenearest workshop to have the brake sys-tem checked - an authorized Volvo work-shop is recommended.
If the brake fluid has fallen below the MINlevel in the brake fluid reservoir, the vehi-cle should not be driven until the brakefluid has been filled. The reason for thebrake fluid loss must be checked.

Brake Assist System
The brake enhancing system, (BAS3), helpsincrease braking force and can thereby reducebraking distance.
The system monitors the driver's braking habitsand 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.

Braking on wet roads
Prolonged driving in heavy rain without brakingmay cause braking effect to be slightly delayedthe first time the brakes are applied.
This may also occur after washing the vehicle. Itwill 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 vehicleor 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 mayform on the brake discs and brake pads.
This could increase stopping distance. Maintainan 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 componentsfor 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 beregularly checked for wear.
Contact a workshop for advice on how to dothis or let a workshop perform the inspection- an authorized Volvo workshop is recom-mended.

Parking brake
The parking brake helps keep the vehicle sta-tionary by mechanically locking two wheels.
The parking brake controls are located in the tunnelconsole 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 brakeis activated, it will only be applied to the rearwheels. If it is activated while the vehicle is mov-ing, the normal brakes will be used on all fourwheels. Braking will be transferred to only therear wheels when the vehicle is almost stopped.

Auto-hold brakes
With the Auto-hold brake function, the driver canrelease 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 activatedautomatically. 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)

Hill Start Assist
The function for assisting when starting the vehi-
cle on inclines (HSA4) helps prevent the vehiclefrom rolling backward when starting on an uphillgradient. When backing up a hill, HSA helpsprevent the vehicle from rolling forward.
The function retains pressure from the brakepedal in the brake system for several secondsafter the brake pedal has been released.
This temporary braking effect is released after afew seconds or when the driver begins driving.
Hill Start Assist is available even when the Auto-hold brake function is switched off.

Braking assist after a collision
In a collision in which the activation level isreached for the pyrotechnic seat belt tensionersor airbags, or if a collision with a large animal isdetected, the vehicle's brakes will be automati-cally activated. This function is intended to helpprevent or reduce the effects of any subsequentcollision.
After a serious collision, it may no longer be pos-sible to control and steer the vehicle. In order toavoid or mitigate a possible further collision witha vehicle or an object in the vehicle's path, thebrake assist system is activated automatically tohelp stop the vehicle safely.
The brake lights and hazard warning flashers areactivated during braking. When the vehicle hasstopped, the hazard warning flashers will con-tinue to flash and the parking brake will beapplied.
If braking is not appropriate, e.g. if there is a riskof being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal.
This function assumes that the brake system isintact after a collision.
Brake assist is part of the Rear Collision Warningand Blind Spot Information safety systems.

Brake - B
From the B position, it is possible to manuallyshift down to lower gears. B can be selected atany time while driving. When the acceleratorpedal is released, the electric motor brakes thevehicle and the hybrid battery is recharged at thesame time. This offers additional opportunities torecharge the hybrid battery, since the battery ischarged even when the brake pedal is notdepressed.
Select brake by moving the gear selector rear-ward from the D position. The currently selectedgear will be displayed in the instrument panel.
Pull the gear selector backward once to shiftdown one gear.
Pull the gear selector backward again to shiftdown to lower gears.
To shift manually to a higher gear, the vehiclemust be equipped with steering wheel paddles*.
Push the gear selector forward to return to Dmode.
For smooth shifting and engine performance, thetransmission will shift down automatically if thevehicle's speed becomes too low for the selectedgear.
