2. Peel off the speed limit sticker from the
side of the compressor. Affix the decal to a clearly visible location on the windshieldto remind the driver not to exceed thisspeed limit. Do not drive faster than80 km/h (50 mph) while using a tire thathas been temporarily repaired with the tiresealing system.
3. Make sure the switch is in the 0 (Off)
position and take out the electric cableand the hose.
4. Unscrew the orange cover on the com- pressor and unscrew the cap on the seal-ing compound bottle.
5. Screw the bottle onto the bottle holder as far as possible. The bottle and the bottle holder are equip- ped with catches to help prevent the seal-ing compound from leaking. Once the bot-tle is screwed into place into the bottleholder, it cannot be unscrewed. The bottle can only be removed by a workshop 18
.
WARNING
Do not unscrew the bottle. It is equipped with a catch to prevent leakage. 6. Unscrew the tire's valve cap and screw
the hose's valve connector as far as possi- ble onto the valve. Be sure the air release valve on the com- pressor's hose is completely closed.
7. Connect the electrical cable to the nearest 12 V outlet and start the vehicle.
NOTE
Make sure that none of the vehicle's other 12 V sockets are used while the compres-sor is running.
WARNING
Never leave children unattended in the vehicle while the engine is running.
WARNING
Inhaling exhaust fumes could lead to seri- ous injury. Never leave the engine runningin an enclosed space or a space withoutsufficient ventilation. 8. Start the compressor by moving the
switch to the I (On) position.
WARNING
Never stand next to a tire being inflated with the compressor. If cracks, bulges, etc.form on the tire, switch off the compressorimmediately. The vehicle should not bedriven. Call roadside assistance to have thevehicle towed to a workshop for inspec-tion/replacement of the tire. Volvo recom-mends an authorized workshop.
NOTE
When the compressor first starts, air pres- sure may temporarily increase up to 6 bar(88 psi) but should decrease again afterapproximately 30 seconds.
9. Inflate the tire for 7 minutes.
CAUTION
To help avoid overheating, the compressor should never be used for more than10 minutes at a time.
18
An authorized Volvo workshop is recommended.

57210. Switch off the compressor and check the
inflation pressure using the air pressure gauge. The inflation pressure should bebetween 1.8 bar (22 psi) and 3.5 bar(51 psi). If the inflation pressure is toohigh, use the air release valve to releaseair.
WARNING
If pressure falls below 1.8 bar (22 psi), the hole in the tire may be too large. The vehi-cle should not be driven. Call roadsideassistance to have the vehicle towed to aworkshop for inspection/replacement ofthe tire. Volvo recommends an authorizedworkshop.
11. Switch off the compressor and remove the electrical cable.
12. Unscrew the hose from the tire's valve and screw the valve cap back on.
NOTE
After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
13. Put the protective hose cover onto the
hose to help prevent leakage of any resid- ual sealing compound. Return the equip-ment to the cargo compartment.
14. Immediately drive the vehicle at least 3 km (2 miles) at a maximum speed of80 km/h (50 mph) to allow the sealingcompound to seal the tire, and thenrecheck the inflation pressure.
WARNING
During the tire's first revolution, some seal- ing compound may spray out of the punc-ture hole. Before driving away, make surethat no one is near the vehicle who couldbe sprayed with sealing compound. Makesure no one is within 2 meters(7 feet) ofthe vehicle.
15. Rechecking the inflation pressure Connect the hose to the tire's valve and screw the hose connector onto the valveas far as possible. The compressor mustbe switched off. 16. Check the inflation pressure on the air
pressure gauge.
If the pressure is under 1.3 bar (19 psi),the tire is not sufficiently sealed. Thevehicle should not be driven. Call road-side assistance to have the vehicletowed.
If the inflation pressure is higher than1.3 bar (19 psi), the tire must be inflatedto the inflation pressure specified onthe tire pressure decal on the driver'sside door pillar (1 bar = 100 kPa =14.5 psi). If the inflation pressure is toohigh, use the air release valve to releaseair.
WARNING
Check inflation pressure regularly.
Volvo recommends driving to the nearest authorized Volvo workshop to have the tirereplaced/repaired. Inform the workshop thatthe tire contains sealing compound. The sealing compound bottle and the hose must be replaced after use. Volvo recom-mends contacting an authorized Volvo work-shop for replacement.

Determining the vehicle's permitted weight
Properly loading your vehicle will provide maximum return of vehicle design perform-ance.
Weight designationsBefore loading your vehicle, familiarize your- self with the following terms for determiningyour vehicle's weight ratings, with or without atrailer, from the vehicle's Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label, and the vehicle's tire informa-tion placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does notinclude passengers, cargo, or optional equip-ment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing,towbar weight is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (front or rear). Thesenumbers are shown on the Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label. The total load on each axlemust never exceed its maximum permissibleweight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passen- gers.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight of occupants and cargo shouldnever exceed XXX kg or XXX lbs." on yourvehicle's placard.
2. Determine the combined weight of the driver and passengers that will be riding inyour vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXXlbs.
4. The resulting figure equals the available amount of cargo and luggage loadcapacity. For example, if the "XXX"amount equals 1400 lbs. and there will befive 150 lb. passengers in your vehicle, theamount of available cargo and luggageload capacity is 650 lbs. (1400 - 750 (5 ×150) = 650 lbs.)
5. Determine the combined weight of lug- gage and cargo being loaded on the vehi-cle. That weight may not safely exceed theavailable cargo and luggage load capacitycalculated in Step 4.
