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.

WARNING
•Exceeding the permissible axle weight, gross vehicle weight, or any otherweight rating limits can cause tireoverheating resulting in permanentdeformation or catastrophic failure.
• Do not use replacement tires withlower load carrying capacities than thetires that were original equipment onthe vehicle because this will lower thevehicle's GVW rating. Use only tireswith the correct load carrying capacity.Consult your Volvo retailer for informa-tion.

NOTE
The air pressure gauge will temporarily show an increase in pressure to approxi-mately 88 psi (6 bar) while the sealingcompound is being pumped into the tire.The pressure should return to a normallevel after approximately 30 seconds.
10. Within seven minutes, inflate the tire tobetween 22—44 psi (1.8—3.0 bar). Switch off the compressor briefly to get aclear reading from the pressure gauge.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
WARNING
If the pressure remains below 22 psi (1.8 bar) after approximately sevenminutes, turn off the compressor. In thiscase, the hole is too large to be sealed andthe vehicle should not be driven.
11. Switch off the compressor and discon-nect the electrical wire from the 12-volt socket. 12. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
CAUTION
•After pumping the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
13. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed of 50 mph (80 km/h) to distributethe sealing compound in the tire.
CAUTION
If your vehicle is equipped with the Tire Pressure Monitoring System (TPMS), theuse of the sealing compound may lead toincorrect tire pressure readings or in rarecases, damage to the tire pressure sensor.Use the tire sealing system to check andadjust the damaged tire's inflation pres-sure.
NOTE
•Safely stow the tire sealing system in a convenient place as it will soon beused again to check the tire’s inflationpressure.
• The empty bottle of sealing compoundcannot be removed from the bottleholder. Consult a trained and qualifiedVolvo service technician to have thebottle removed and properly disposedof.
WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur whiledriving, reduce speed and park the vehiclein a safe place. Recheck the tire forbumps, cracks, or other visible damage,and recheck its inflation pressure. If thepressure is below 19 psi (1.3 bar), do notcontinue driving. Have the vehicle towedto a trained and qualified Volvo servicetechnician.
Stage 2: Checking inflation pressure1. Connect the tire sealing system as
described in stage 1.
2. Refer to the inflation pressure tables for the correct inflation pressure. If the tire needs to be inflated, start the tire sealing

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.
