If the light comes on while driving, stop the vehicle, stop the engine immediately, andcheck the engine oil level. Add oil if neces-sary. If the oil level is normal and the lightstays on after restart, have the vehicle towedto the nearest trained and qualified Volvoservice technician.
Parking brake applied
This symbol flashes while the brake is being applied and then glows steadily when theparking brake has been set. See page 138 for more information about using the parking brake.
Airbags – SRS
If this light comes on while the vehicle is being driven, or remains on for longer thanapproximately 10 seconds after the vehiclehas been started, the SRS system's diagnos-tic functions have detected a fault in a seatbelt lock or pretensioner, a front airbag, sideimpact airbag, and/or an inflatable curtain.Have the system(s) inspected by a trainedand qualified Volvo service technician assoon as possible. See page 21 for more information about the airbag system.
Seat belt reminder
This symbol comes on for approximately 6 seconds if the driver has not fastened his orher seat belt.
Generator not charging
This symbol comes on during driving if a fault has occurred in the electrical system. Contactan authorized Volvo workshop.
Engine temperatureEngine overheating can result from low oil or coolant levels, towing or hard driving at highheat and altitude, or mechanical malfunction.Engine overheating will be signaled with textand a red warning triangle in the middle of theinstrument display. The exact text will dependon the degree of overheating. It may rangefrom
High engine temp Reduce speed toHigh engine temp Stop engine. If appropri-
ate, other messages, such as Coolant level
low, Stop safely will also be displayed. If
your engine does overheat so that you must stop the engine, always allow the engine tocool before attempting to check oil and cool-ant levels. See page 332 for more information.
Fault in brake system
If this symbol lights, the brake fluid level may be too low. Stop the vehicle in a safe placeand check the level in the brake fluid reser-voir, see page 332. If the level in the reservoiris below MIN, the vehicle should be transpor-
ted to an authorized Volvo workshop to havethe brake system checked. If the

at the same time, there may be a fault in the brake force distribution system.
1. Stop the vehicle in a safe place and turn off the engine.
2. Restart the engine.
• If both symbols extinguish, continue driv- ing.
• If the symbols remain on, check the levelin the brake fluid reservoir, see page 332.If the brake fluid level is normal but the

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. An extramat on the driver's floor can cause theaccelerator and/or brake pedal tocatch. Check that the movement ofthese pedals is not impeded.
• 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.
2 If the vehicle is moving, it is only necessary to press the START/STOP ENGINE button to start the vehicle.

WARNING
•Always remove the remote key from the ignition slot when leaving the vehi-cle and ensure that the ignition inmode
0 (see page 85 for information
about the ignition modes), especially ifthere are children in the vehicle.
• On vehicles with the optional keylessdrive, never remove the remote keyfrom the vehicle while it is being drivenor towed.
• Always place the gear selector in Parkand apply the parking brake beforeleaving the vehicle. Never leave thevehicle unattended with the enginerunning.
• Always open garage doors fully beforestarting the engine inside a garage toensure adequate ventilation. Theexhaust gases contain carbon monox-ide, which is invisible and odorless butvery poisonous.
NOTE
•After a cold start, idle speed may be noticeably higher than normal for ashort period. This is done to help bringcomponents in the emission controlsystem to their normal operating tem-perature as quickly as possible, whichenables them to control emissions andhelp reduce the vehicle's impact on the environment 3
.
CAUTION
• When starting in cold weather, the automatic transmission may shift up atslightly higher engine speeds than nor-mal until the automatic transmissionfluid reaches normal operating tem-perature.
• Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
• The engine should be idling when youmove the gear selector. Never acceler-ate until after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harshengagement and premature transmis-sion wear.
• Selecting
P or N when idling at a
standstill for prolonged periods of timewill help prevent overheating of theautomatic transmission fluid.
3 If the gear selector is in the D or R positions and the car is not moving, engine speed (rpm) will be lower and it will take longer for the engine to reach normal operating temperature.

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 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 138.
CAUTION
The vehicle must be stationary when posi- tion P is selected.

load. See the "Tire pressure" section. Loads should be distributed so that capacity weightor maximum permissible axle loads are notexceeded.
Driving through water
•
The vehicle can be driven through water up to a depth of approximately 10 in.(25 cm), at a maximum speed of 6 mph(10 km/h).
• Take particular care when driving throughflowing water.
• Clean the electrical connections for trailerwiring after driving in mud or water.
• When driving through water, maintain lowspeed and do not stop in the water.
WARNING
•Avoid driving through standing or rushing water. Doing so can be dan-gerous and it may also be difficult todetermine the actual depth of thewater.
• If water cannot be avoided, after driv-ing through the water, press lightly onthe brake pedal to ensure that thebrakes are functioning normally. Wateror mud can make the brake liningsslippery, resulting in delayed brakingeffect.
CAUTION
•Engine damage will occur if water is drawn into the air cleaner.
• If the vehicle is driven through waterdeeper than 10 in (25 cm), water mayenter the differential and the transmis-sion. This reduces the oil's lubricatingcapacity and may shorten the servicelife of these components.
• Do not allow the vehicle to stand inwater up to the door sills longer thanabsolutely necessary. This could resultin electrical malfunctions.
• If the engine has been stopped whilethe vehicle is in water, do not attemptto restart it. Have the vehicle towedout of the water.
Engine and cooling systemUnder special conditions, for example when driving in hilly terrain, extreme heat or withheavy loads, there is a risk that the engineand cooling system will overheat. Proceed asfollows to avoid overheating the engine. •
Maintain a low speed when driving with a trailer up long, steep hills.
• Do not turn the engine off immediatelywhen stopping after a hard drive.
WARNING
The cooling fan may start or continue to operate (for up to 6 minutes) after theengine has been switched off.
• Remove any auxiliary lights from in front of the grille when driving in hot weatherconditions.
• Do not exceed engine speeds of4500 rpm if driving with a trailer in hillyterrain. The oil temperature could becometoo high.
Conserving electrical currentKeep the following in mind to help minimize battery drain:
• When the engine is not running, avoid using ignition mode
II. Many electrical
systems (the audio system, the optionalnavigation system, power windows, etc)will function in ignition modes 0 and I.
These modes reduce drain on the battery.
• Please keep in mind that using systems,accessories, etc., that consume a greatdeal of current when the engine is notrunning could result in the battery beingcompletely drained. Driving or having theengine running for approximately15 minutes will help keep the batterycharged.

If necessary, the fuel filler door can be opened manually:
1. Open the side hatch in the trunk (on thesame side as the fuel filler door).
2. Grasp the handle on the green cord.
3. Gently pull the cord straight rearward until the fuel filler door clicks open.
Opening/closing the fuel cap
G022915
Fuel vapor expands in hot weather. Open the filler cap slowly. After refueling, close the fuel filler cap by turning it clockwise until it clicks into place.
CAUTION
•Do not refuel with the engine running 3
.
Turn the ignition off or to position I. If
the ignition is on, an incorrect reading could occur in the fuel gauge.
• Avoid overfilling the fuel tank. Do notpress the handle on the filler nozzlemore than one extra time. Too muchfuel in the tank in hot weather condi-tions can cause the fuel to overflow.Overfilling could also cause damage tothe emission control systems.
Emission controls
Three-way catalytic converter
•
Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle ifyou detect engine misfire, noticeable lossof power or other unusual operating con-ditions, such as engine overheating orbackfiring. A properly tuned engine will

help avoid malfunctions that could dam- age the three-way catalytic converter.
• Do not park your vehicle over combusti-ble materials, such as grass or leaves,which can come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
• Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cat-alytic converter or exhaust system over-heating.
• Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehiclemay be illegal and can cause three-waycatalytic converter or exhaust systemoverheating. This includes: altering fuelinjection settings or components, alteringemission system components or locationor removing components, and/or repea-ted use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readings are fed into a control module that continu-ously monitors engine functions and controlsfuel injection. The ratio of fuel to air into theengine is continuously adjusted for efficientcombustion to help reduce harmful emis-sions.
