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) 1HSA 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 88) 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.

engaged from the engine and engine rpm will be reduced to the idle level(approx. 700-800 rpm), which helps reducefuel consumption. This feature is primarily intended to be used in driving situations where a decrease inspeed is expected, such as when approach-ing an intersection or a traffic light.
Eco Coast enables proactive driving with as little braking as possible.
Combinations of On and OffDepending on the driving situation, Eco can be used in different ways to help reduce fuelconsumption:
• Eco activated
: this enables Eco Coast,
which allows the vehicle to roll freely for
as far as possible when the driver relea-
ses the accelerator pedal (e.g., when approaching a traffic light or intersection).
or
• Eco deactivated
: engine braking can be
used when the vehicle will only roll for
a short distance (in heavy traffic, etc.) or
when driving down hills .
To help keep fuel consumption as low as possible, Eco Coast should not be used intraffic situations where the brakes have toused frequently.
Activating Eco CoastEco Coast is activated when the accelerator pedal is released completely if:
• Eco is activated
• The gear selector is in
D
• The vehicle's speed is between approxi- mately 40–85 mph (65–140 km/h). Alwaysobserve posted speed limits
• The gradient of a down-slope is less thanapproximately 6%
Deactivating Eco CoastIn certain situations, it may be advisable to switch off the Eco Coast function, such as:
• When driving down steep hills, in order to utilize engine braking
• Prior to passing another vehicle, in orderto do so as safely as possible
Deactivating Eco Coast (and reactivating engine braking) can be done in the followingways:
• Press the
ECO button on the center con-
sole
• Move the gear selector to the manual "
S
+/– " position
• Change gears using the steering wheel paddles*
• Press the brake or accelerator pedal
Eco Coast limitationsThis function will not be available if:
• Cruise control is activated
• The gradient of a down-slope is morethan approximately 6%
• The steering wheel paddles* are used tomanually change gears
• The engine and/or transmission have notreached their normal operating tempera-ture
• The gear selector is moved from
D to the
manual " S+/–" position
• The vehicle's speed is not within the40–85 mph (65–140 km/h). interval

Introduction
Start/Stop is a function that is available with certain engines/transmissions. It temporarilyswitches off the engine when the vehicle isnot moving, for instance in heavy traffic or ata traffic light to help reduce fuel consumption.
Function and use
Start/Stop symbol in the instrument panel
Start/Stop button on the center console
Start/Stop is activated automatically each time the engine is started 1
. The symbol in the
instrument panel will be displayed for several seconds when the engine starts and the indi-cator light in the On/Off button will remainilluminated while the function is activated. All of the vehicle's systems will function while the engine is auto-stopped, although the function of certain systems may reduced atthis time. For example, blower speed andhigh infotainment system volume may bereduced to help conserve the battery'scapacity.
Auto-stopping the engineNormally, when Start/Stop is activated andthe brakes are applied until the vehicle comesto a standstill, the engine will auto-stop auto-matically
if the driver keeps the brake pedal
depressed .
To remind the driver that the enginehas been auto-stopped, theStart/Stop symbol will illuminate inthe instrument panel and remain on
until the engine restarts.
If the ECO function* (see page 134) is activated, theengine may auto-stop beforethe vehicle comes to a com-plete standstill.
Auto-starting the engineThe engine restarts as soon as the driver releases the brake pedal.
Deactivating Start/StopIn certain situations (e.g.,driving in heavy, stop-and-gotraffic), it may be preferableto deactivate Start/Stop. This is done by pressing the button in the center console.
The indicator light in the button will go out. Start/Stop will remain deactivated until the button is pressed again or until the engine isswitched off and restarted by the driver.
Hill Start Assist (HSA)When starting on steep hills, HSA (see page 127) retains 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 afterseveral seconds or when the driver pressesthe accelerator pedal.
1 Not when the engine is started using the optional Engine Remote Start feature, see page 124

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 331 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.
