Generator not chargingThis 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 range from
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 Engine compartment – coolant (p. 316) for more information.
Fault in brake systemIf 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 Engine compartment – brake fluid(p. 317). If the level in the reservoir is belowMIN , the vehicle should be transported to an
authorized Volvo workshop to have the brakesystem checked. If the
and symbols come on
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 Enginecompartment – brake fluid (p. 317). If thebrake fluid level is normal but the sym-bols are still lit, the vehicle can be driven,with great care, to an authorized Volvoworkshop to have the brake systemchecked.
• If the level in the reservoir is below
MIN,
the vehicle should be transported to anauthorized Volvo workshop to have thebrake system checked.WARNING
• If the fluid level is below the
MIN mark
in the reservoir or if a warning mes- sage is displayed in the text window:DO NOT DRIVE . Have the vehicle
towed to a trained and qualified Volvoservice technician and have the brakesystem inspected.
• If the
and symbols
are on at the same time, there is a risk of reduced vehicle stability.
Warning symbolThe red warning symbol lights up to indicate a problem related to safety and/or drivability.A message will also appear in the instrumentpanel. The symbol remains visible until thefault has been rectified but the text messagecan be cleared with the OK button, see Infor-
mation display – menu controls (p. 106). Thewarning symbol can also come on in conjunc-tion with other symbols. Action:
1. Stop in a safe place. Do not drive the vehicle further.
2. Read the information on the display. Implement the action in accordance with the message in the display. Clear themessage using OK.

Tailgate wiper/washer
The tailgate wiper operates at two speeds: intermittent and continuous.
NOTE
The rear wiper is equipped with a cut-off function, which means that it will not oper-ate if its electric motor overheats. Thewiper will function again after a cool-downperiod (30 seconds or longer, dependingon the heat of the motor and ambient tem-perature conditions).
Tailgate wiper and reverse gearIf the windshield wipers are on and the trans- mission is put into reverse gear, the tailgatewiper will go into intermittent wiping func- tion18
. This function is deactivated when a dif-
ferent gear is selected.
NOTE
On vehicles with the optional rain sensor, the tailgate wiper will be activated whenreverse is selected, if the rain sensor isactivated and it is raining.
If the tailgate wiper is in the normal (continu- ous) wiping mode, selecting different gearswill not affect its function.

The driver will then have to reactivate ACC in one of the following ways:
• By pressing
•By accelerating up to at least 3 mph (4 km/h). ACC will then resume followingthe vehicle ahead.
Your vehicle will then resume following the vehicle ahead at the set time interval.
NOTE
ACC can remain active and keep your vehicle at a standstill for up to 4 minutes.After 4 minutes have elapsed, the parkingbrake will be engaged and ACC will go intostandby mode. To reactivate ACC, the driver must release the parking brake (see Parking brake –general information (p. 254)).
Automatic standby mode when ACC changes target vehicles
If the vehicle ahead turns suddenly, there may be a stationary vehicle ahead The following only applies at speeds below approximately 18 mph (30 km/h)
:
If ACC changes target vehicles (the vehicle that the radar sensor has detected) from amoving vehicle to a stationary one, the sys-tem will apply the brakes in your vehicle.
WARNING
At speeds above 18 mph (30 km/h), ACC
will not react to a stationary vehicle and apply the brakes but will instead acceler-ate to the previously set speed. The drivermust actively apply the brakes to stop thevehicle.
ACC disengages and goes into standby mode if:
• Your vehicle's speed goes below 10 mph (15 km/h) and ACC cannot determine ifthe target object is a stationary vehicle orsome other type of object such as e.g., aspeed bump.
• Your vehicle's speed goes below 10 mph(15 km/h) and the vehicle ahead turns sothat ACC no longer has a target vehicle tofollow.
No automatic braking when at a standstill
In certain situations, ACC will no longer apply the brakes and go into standby mode whilethe vehicle is not moving. This means that thedriver will have to apply the brakes. This happens if:
• The driver presses the brake pedal
• The parking brake is activated
• The gear selected is moved to
P, N or R
• The driver presses the
button to put
ACC in standby mode
The parking brake is applied automatically
In certain situations, ACC will apply the park- ing brake in order to continue keeping thevehicle at a standstill. This happens if:
• The driver opens the door or takes off his/her seat belt
• The stability system is put in Sport mode(see Stability system – operation (p. 163))
• ACC has kept the vehicle at a standstillfor more than 2 minutes
• The engine has been switched off
• The brakes have overheated

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.

WARNING
•Always remove the remote key from the ignition slot when leaving the vehi-cle and ensure that the ignition inmode
0 (see Ignition modes (p. 73) for
information about the ignition modes).
• 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.

Engine and cooling system
Under special conditions, for example when driving in hilly terrain, extreme heat or withheavy loads, there is a risk that the engine andcooling system will overheat. Proceed as follows to avoid overheating the engine. •Maintain a low speed when driving with a trailer up long, steep hills. For informa-tion, see Towing a trailer (p. 267)
• 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 current
Keep 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.
• The optional 12-volt socket in thetrunk (p. 135) area provides electrical cur-rent even with the ignition switched off,which drains the battery.
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo serv-ice technician before driving long distances.Your retailer will also be able to supply youwith bulbs, fuses, spark plugs and wiperblades for your use in the event that problemsoccur. As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and that fuel consumption is normal.
• Check for fuel, oil, and fluid leakage.
• Have the transmission oil level (p. 362)checked.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (the spare tire aswell), and replace those that areworn (p. 275). Check tire pres-sure (p. 282).
• The brakes, front wheel alignment, andsteering gear should be checked by atrained and qualified Volvo service techni-cian only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to

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 willhelp 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 location or 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. Readingsare 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.

Economical driving
Better driving economy may be obtained by thinking ahead, avoiding rapid starts andstops and adjusting the speed of your vehicleto immediate traffic conditions.
Economical driving conserves natural resources
Observe the following rules:
• Bring the engine to normal operating tem- perature as soon as possible by drivingwith a light foot on the accelerator pedalfor the first few minutes of operation. Acold engine uses more fuel and is subjectto increased wear.
• Whenever possible, avoid using the vehi-cle for driving short distances. This doesnot allow the engine to reach normaloperating temperature.
• Drive carefully and avoid rapid accelera-tion and hard braking.
• Use the transmission's Drive (
D) position
as often as possible and avoid using kick-down.

Towing a trailer
When towing a trailer, always observe the legal requirements of the state/province.
NOTE
For the maximum trailer and tongue weights recommended by Volvo, seeWeights (p. 357).
•All Volvo models are equipped with energy-absorbing shock-mounted bump-ers. Trailer hitch installation should notinterfere with the proper operation of thisbumper system.
Trailer towing does not normally present any particular problems, but take into considera-tion: • Increase tire pressure to recommended full pressure, see Tire inflation – pressuretable (p. 285).
• When your vehicle is new, avoid towingheavy trailers during the first 620 miles(1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine cool-ant temperature should be closelywatched when driving in hot climates orhilly terrain. Use a lower gear and turn offthe air conditioner if the temperaturegauge needle enters the red range. •
If the automatic transmission begins tooverheat, a message will be displayed inthe text window.
• Avoid overload and other abusive opera-tion.
• Hauling a trailer affects handling, durabil-ity, and economy.
• It is necessary to balance trailer brakeswith the towing vehicle brakes to providea safe stop (check and observe state/local regulations).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch isnot being used.
NOTE
• When parking the vehicle with a trailer on a hill, apply the parking brakebefore putting the gear selector in
P.
Always follow the trailer manufactur-er's recommendations for wheelchocking.
• When starting on a hill, put the gearselector in
D before releasing the park-
ing brake.
• If you use the manual (Geartronic) shiftpositions while towing a trailer, makesure the gear you select does not puttoo much strain on the engine (usingtoo high a gear).
• The drawbar assembly/trailer hitchmay be rated for trailers heavier thanthe vehicle is designed to tow. Pleaseadhere to Volvo's recommended trailerweights.
• Avoid driving with a trailer on inclinesof more than 15%.
