Starting the engine
The engine can be started/switched off using the remote key and the START/STOP
ENGINE button.
Ignition slot with remote key inserted (see Igni- tion modes (p. 73) for more information on igni-tion modes)
WARNING
Before starting the engine:
• Fasten the seat belt.
• Check that the seat, steering wheel and mirrors are adjusted properly.
• Make sure the brake pedal can bedepressed completely. Adjust the seatif necessary.
WARNING
•Never use more than one floor mat at a time on the driver's floor. Beforedriving, remove the original mat fromthe driver's seat floor before using anyother type of floor mat. Any mat usedin this position should be securely andproperly anchored in the attachingpins. An extra mat on the driver's floorcan cause the accelerator and/orbrake pedal to catch. Check that themovement of these pedals is not impe-ded.
• Volvo's floor mats are specially manu-factured for your car. They must befirmly secured in the clips on the floorso that they cannot slide and becometrapped under the pedals on the driv-er's side.
1. Press the remote key into the ignition slot
as far as possible, with the metallic key blade pointing outward (not inserted into the slot) 1
.
2. Depress the brake pedal 2
. 3. Press and release the
START/STOP
ENGINE button. The autostart function
will operate the starter motor until the engine starts or until its overheating func-tion stops it. The starter motor operates for a maxi- mum of 10 seconds. If the engine has notstarted, repeat the procedure.
CAUTION
If the engine does not start after the third try, wait for approximately 3 minutesbefore trying to start it again to give thebattery time to recover its startingcapacity.
NOTE
Keyless drive *
To start a vehicle equipped with the key- less drive feature, one of the remote keysmust be in the passenger compartment.Follow the instructions in steps 2 and 3 tostart the vehicle.
1 On vehicles with the optional keyless drive, it is only necessary to have a remote key in the passenger’s compartment.

Geartronic: steering wheel paddles*In addition to the manual gearshift function using the gear selector, this option makes itpossible to manually shift gears from thesteering wheel.
Steering-wheel mounted gear shift paddles
" – ": Shift down to a lower gear.
"+ ": Shift up to a higher gear.
In order to shift gears with the paddles, they have to first be activated. The gear selector
can be in either the D or S position. Activating the paddles:
• Pull either paddle toward the steering wheel and release it; the
D in the instru-
ment panel will change to the number ofthe gear currently being used.
Shifting gears: •
Pull the paddle toward the steering wheeland release it.
Deactivating the paddles: • Hold the "
+" paddle for approximately
3 seconds.
NOTE
If the gear selector was in D when paddle
shifting was activated ( D changed to the
number of the gear being used), the trans- mission will automatically revert to D after
approximately 5 seconds if the paddlesare not used to shift gears. This will not occur:
• during active driving (e.g., on a wind- ing road, while accelerating, etc)
• if the gear selector was in
S when the
paddles were activated
If the transmission reverts to D, the pad-
dles will have to be reactivated (pull either paddle toward the steering wheel andrelease it) before they can be used to shiftgears again. The paddles can also be manually deacti- vated by pulling both paddles toward thesteering wheel and holding them until thegear number shown in the instrumentpanel changes to D.
Geartronic: Sport mode (S) 7This transmission mode provides sportier shifting characteristics and enables a moreactive driving style by making it possible todrive at higher rpm in each gear before shift-ing up. The engine also responds faster whenthe accelerator pedal is pressed. To access Sport mode from Drive (
D), move
the gear selector to the left. The transmission will not switch to manual shifting mode untilthe gear selector is moved forward or rear-ward toward + or –. Sport mode can be selected any time.
NOTE
• On vehicles equipped with Sport mode, the transmission symbol in themain instrument panel will changefrom
D to S when the gear selector is
moved to the manual shifting mode. Ifthe gear selector is moved toward "+"or "-", the number of the gear currentlybeing used will be displayed, see Infor-mation displays – introduction (p. 62).
• Please be aware that using Sportmode may result in a slight decrease infuel economy. Driving in
D can help
improve fuel economy.

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:
• With Eco activated
: this enables Eco
Coast, which allows the vehicle to roll
freely for as far as possible when the
driver releases the accelerator pedal (e.g., when approaching a traffic light or inter-section).
or
• With 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 to beused 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
Additional information and settings
Other ECO-related settings can be made in the vehicle's
MY CAR menu. See My Car –
introduction (p. 70) for more information.

All Wheel Drive (AWD)
Your Volvo can be equipped with permanent All Wheel Drive, which means that power isdistributed automatically between the frontand rear wheels.
Under normal driving conditions, most of the engine's power is directed to the frontwheels. However, if there is any tendency forthe front wheels to spin, an electronicallycontrolled coupling distributes power to thewheels that have the best traction.
NOTE
The message AWD disabled Service
required will be appear in the information
display if an electrical fault should occur in the AWD system. A warning light will alsoilluminate in the instrument panel. If thisoccurs, have the system checked by atrained and qualified Volvo service techni-cian.
Related information
• Transmission – general information (p. 238)
Brakes – general
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 Changing a wheel –removing wheel (p. 276) for informationabout using the jack and removing a wheel)and performing a visual inspection of thebrake 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.
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 through an automatic car wash can cause water tocollect on the brake discs and pads. This willcause a delay in braking effect when thepedal 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.
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 by
