Shiftgate positions
Depress the button on the front of the gear selector knob to move the gear selectorbetween the R, N , D , and P positions.
The gear selector can be moved freelybetween the Geartronic (manual shifting) andDrive ( D) positions while driving.
CAUTION
The transmission’s temperature is moni- tored to help prevent damage to the trans-mission or other drivetrain components. Ifthere is a risk of overheating, the warningsymbol on the instrument panel will illumi-nate and a text message will be displayed.Follow the instructions provided there.
Hill Start Assist (HSA)HSA makes it easier to start or back up on a hill by retaining pressure on the brake pedalfor several seconds after the pedal has beenreleased in order to keep the vehicle at astandstill. The brakes will be released after several sec- onds or when the driver presses the accelera-tor pedal.
Park: position PSelect the P position when starting or park-
ing.
ShiftlockWhen P has been selected, the transmission
is mechanically blocked in this position. The brake pedal must be depressed and the igni-tion must be in at least mode II (see page 84)
before the gear lever can be moved from theP position.
WARNING
Always apply the parking brake when the vehicle is parked, particularly when park-ing on a hill. The transmission's P mode
may not be able to keep the vehicle sta-tionary if it is parked on an incline.
Press the control to apply the parking brake, see page 130.
CAUTION
The vehicle must be stationary when posi- tion P is selected.
Gear indicatorThe gear currently being used is displayed on the rightside of the instrument panel. The " S" symbol turns orange
if Sport mode is being used.
Reverse: position RThe vehicle must be stationary when position R is selected.

* Option/accessory, for more information, see Introduction.127
Brake system
The brake system is a hydraulic system con- sisting of two separate brake circuits. If aproblem should occur in one of these circuits,it is still possible to stop the vehicle with theother brake circuit. If the brake pedal must be depressed farther than normal and requires greater foot pres-sure, the stopping distance will be longer. A warning light in the instrument panel will light up to warn the driver that a fault hasoccurred. If this light comes on while driving or braking, stop immediately and check the brake fluidlevel in the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal – do not pump thebrakes.
WARNING
If the fluid level is below the MIN mark in
the reservoir or if a brake system message is shown in the information display: DO
NOT DRIVE . Have the vehicle towed to a
trained and qualified Volvo service techni-cian and have the brake system inspected.
Brake pad inspectionOn vehicles equipped with a jack*, the condi- tion of the brake pads can be checked byraising the vehicle (see page 308 for informa-tion about using the jack and removing awheel) and performing a visual inspection ofthe brake pads.
WARNING
• If the vehicle has been driven immedi- ately prior to a brake pad inspection,the wheel hub, brake components,etc., will be very hot. Allow time forthese components to cool before car-rying out the inspection.
• Apply the parking brake and put thegear selector in the Park (
P) position.
• Block the wheels standing on theground, use rigid wooden blocks orlarge stones.
WARNING
•Use the jack intended for the vehicle when changing a tire. For any otherjob, use stands to support the vehicle.
• The jack should be kept well-greasedand clean, and should not be dam-aged.
• Be sure the jack is on a firm, level,non-slippery surface.
• No objects should be placed betweenthe base of jack and the ground, orbetween the jack and the attachmentbar on the vehicle.
• The jack must correctly engage thejack attachment.
• Never allow any part of your body tobe extended under a vehicle suppor-ted by a jack.
Brake lightsThe brake lights come on automatically when the brakes are applied.
Adaptive brake lightsThe adaptive brake lights activate in the event of sudden braking or if the ABS system isactivated. This function causes an additionaltaillight on each side of the vehicle to illumi-nate to help alert vehicles 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 aboveapproximately 6 mph (10 km/h)
When the vehicle has come to a stop, the brake lights and additional taillights remain onfor as long as the brake pedal is depressed oruntil braking force on the vehicle is reduced.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is run-ning. Never let the vehicle roll to a stop withthe engine switched off. If the power brakes are not working, consid- erably higher pressure will be required on thebrake pedal to compensate for the lack ofpower assistance. This can happen for exam-ple when towing your vehicle or if the engineis switched off when the vehicle is rolling. Thebrake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing throughan automatic car wash can cause water tocollect on the brake discs and pads. This willcause a delay in braking effect when the pedal is depressed. To avoid such a delaywhen the brakes are needed, depress thepedal occasionally when driving through rain,slush, etc. This will remove the water from thebrakes. Check that brake application feelsnormal. This should also be done after wash-ing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strainwhen driving in mountains or hilly areas, orwhen towing a trailer. Vehicle speed is usuallyslower, which means that the cooling of thebrakes is less efficient than when driving onlevel roads. To reduce the strain on thebrakes, shift into a lower gear and let theengine help with the braking. Do not forgetthat if you are towing a trailer, the brakes willbe subjected to a greater than normal load.
Anti-lock braking system (ABS)The Anti-lock Braking System (ABS) helps toimprove vehicle control (stopping and steer-ing) during severe braking conditions by limit-ing brake lockup. When the system "senses"impending lockup, braking pressure is auto-matically modulated in order to help preventlockup that could lead to a skid. The system performs a brief self-diagnostic test when the engine has been started anddriver releases the brake pedal. Another auto-matic test may be performed when the vehi-
cle first reaches a speed of approximately6 mph (10 km/h). The brake pedal will pulsateseveral times and a sound may be audiblefrom the ABS control module, which is nor-mal.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. Thisdelay is minimized by cleaning the brake lin-ings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and afterthe vehicle has been washed. Do this bybraking gently for a short period while thevehicle is moving.
Emergency Brake AssistanceEBA is designed to provide full brake effectimmediately in the event of sudden, hardbraking. The system is activated by the speedwith which the brake pedal is depressed. When the EBA system is activated, the brake pedal will go down and pressure in the brakesystem immediately increases to the maxi-mum level. Maintain full pressure on thebrake pedal in order to utilize the systemcompletely. EBA is automatically deactivatedwhen the brake pedal is released.

NOTE
•When the EBA system is activated, the brake pedal will go down and pressurein the brake system immediatelyincreases to the maximum level. Youmust maintain full pressure on thebrake pedal in order to utilize the sys-tem completely. There will be no brak-ing effect if the pedal is released. EBAis automatically deactivated when thebrake 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 pedalwill return to its usual position when itis released.
