NOTE
Your vehicle is equipped with a KEYLOCK
system. When the engine is switched off, the gear selector must be in the P position
before the key can be removed from theignition switch. When starting in cold weather, the trans- mission may shift up at slightly higherengine speeds than normal until the auto-matic transmission fluid reaches normaloperating temperature.
NOTE
Do not race a cold engine immediately after starting. Oil flow may not reach somelubrication points fast enough to preventengine damage.
WARNING
Always place the gear selector in Park and apply the parking brake before leaving thevehicle. Never leave the vehicle unatten-ded with the engine running.
• Always open garage doors fully before starting the engine inside a garage toensure adequate ventilation. Theexhaust gases contain carbon monox-ide, which is invisible and odorless butvery poisonous.
CAUTION
Automatic transmission
• The engine should be idling when you move 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.

P (Park)Use this position when starting the engine or parking the vehicle. Never use P while the vehicle is in motion.
The parking brake should also be set when- ever the vehicle is parked. The gear selector is mechanically locked in the P position (SHIFTLOCK). To release
the gear selector from this position, the engine must be running (or the ignition keymust be in position II) and the brake pedal
must be depressed.
N (Neutral)Neutral – no gear engaged. Use the parkingbrake.
WARNING
Never leave the vehicle unattended when the engine is running. If, by mistake, thegear selector is moved from P, the vehicle
may start moving.
R (Reverse)Never engage R while the vehicle is moving.
D (Drive)D is the normal driving position and should be used as often as possible to help improve fueleconomy. The vehicle should not be movingwhen shifting from R to the D position.
NOTE
The transmission has 6 forward speeds.

Shift gate positions
Depress the button on the front of the gear selector knob to move between the R, N, D,
and P positions.
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.

Points to keep in mind when towing a trailer
•When towing trailers
without brakes, the
maximum permissible trailer weight is 1,700 lbs (750 kg).
• If necessary, redistribute the weight ofany cargo in the trailer to avoid excessiveweight on the trailer hitch.
• The maximum trailer weight listed in thetable for All Wheel Drive models,5,000 lbs (2250 kg) is only applicablewhen there are not more than two occu-pants in the vehicle, in the front seats,with a combined weight of 300 lbs(135 kg), with no other cargo in the vehi-cle.
• The maximum weight listed for FrontWheel Drive models, 4,000 lbs (1800 kg)is only applicable when there are notmore than four occupants in the vehicle,in the front seats and second row ofseats, with a combined weight of 600 lbs(270 kg), with no other cargo in the vehi-cle.
• Vehicles used for towing a trailer on aregular basis, or for long-distance high-way towing should be equipped with anautomatic transmission oil cooler andVolvo's automatic self-leveling system forthe rear suspension. Consult your Volvoretailer. •
Volvo recommends the use of Volvotrailer hitches that are specially designedfor the vehicle.
• All Volvo models are equipped withenergy-absorbing shock-mounted bump-ers. Trailer hitch installation should notinterfere with the proper operation of thisbumper system.
• Increase tire pressure to recommendedfull inflation pressure. See chapter"Wheels and tires."
• When your vehicle is new, avoid towingheavy trailers during the first 620 miles(1,000 km).
• 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.
• 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.
• Remove the ball and drawbar assemblywhen the hitch is not being used.
• Volvo recommends the use of syntheticengine oil when towing a trailer over longdistances or in mountainous areas.
NOTE
•When parking the vehicle with a trailer on a hill, apply the parking brakebefore putting the gear selector in
P.
When starting on a hill, put the gearselector in D before releasing the park-
ing brake. Always follow the trailermanufacturer's recommendations forwheel chocking.
• 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).

system’s compressor. If necessary, release air from the tire by turning the airrelease knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
WARNING
If you interrupt your trip for more than 1 hour, check the inflation pressure in thedamaged tire again before continuing.
Replacing the sealing compound container
The sealing compound container must be replaced if:• the tire sealing system has been used to repair a tire
• the container’s expiration date haspassed (see the date on decal).
NOTE
• After use, the sealing compound bot- tle, the hose, and certain other systemcomponents must be replaced. Pleaseconsult your Volvo retailer for replace-ment parts.
• If the sealing compound bottle’s expi-ration date has passed, please take itto a Volvo retailer or a recycling stationthat can properly dispose of harmfulsubstances.
Inflating tires
The tire sealing system can be used to inflate the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position 0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s inflation valve and screw the hose con- nector onto the valve as tightly as possi-ble by hand.
5. Connect the electrical wire to the nearest 12-volt socket in the vehicle. 6. Start the vehicle’s engine.
WARNING
•
The vehicle’s engine should be running when the tire sealing system is used toavoid battery drain. Therefore, be surethe vehicle is parked in a well ventilatedplace, or outdoors, before using thesystem. The parking brake should besecurely applied and the gear selectorshould be in the
P (park) position.
• Children should never be left unatten-ded in the vehicle when the engine isrunning.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to get a clear reading from the pressuregauge.
8. Refer to the tire inflation tables for the correct inflation pressure. If the tire needsto be inflated, start the tire sealing sys-tem’s compressor (press the on/offswitch to position I). If necessary, releaseair from the tire by turning the air releaseknob counterclockwise.

Three-way catalytic converter - general information
•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, the Elec-tronic Control Module, or the vehicle maybe illegal and can cause three-way cata-lytic converter or exhaust system over-heating. This includes: altering fuel injec-tion settings or components, altering emission system components or location,or removing components, and/the repea-ted use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
