NOTE
To help avoid incorrect tire inflation pressure, if possible only inflate the tires when they arecold. The tires are considered to be coldwhen they have the same temperature as thesurrounding (ambient) air. This temperature isnormally reached after the vehicle has beenparked for at least 3 hours. After driving a dis-tance of approximately 1 mile (1.6 km), thetires are considered to be warm.
CAUTION
When inflating tires with TPMS sensors, press the pump's mouthpiece straight onto thevalve to help avoid bending or otherwise dam-aging the valve.
CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
WARNING
• Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
• Tire monitoring systems cannot indicatesudden tire damage caused by externalfactors (e.g., a blowout) in advance.

ice technician to have the bottle removed and properly disposed of.
WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reducespeed and park the vehicle in a safe place.Recheck the tire for bumps, cracks, or othervisible damage, and recheck its inflation pres-sure. If the pressure is below 19 psi (1.3 bar),do not continue driving. Have the vehicletowed to a trained and qualified Volvo servicetechnician.
15. Rechecking the pressure Reconnect the tire sealing system's hose to the tire's inflation valve. 16. Without starting the compressor, check the
inflation pressure on the air pressure gauge. •If the pressure is under 19 psi (1.3 bar), the puncture has not been sealed suffi-ciently and the vehicle should not bedriven. Have the vehicle towed to a trainedand qualified Volvo service technician.
• If the pressure is more than 19 psi(1.3 bar), connect the electrical wire to a12-volt socket, start the compressor andinflate the tire to the correct pressure(see the tire pressure decal on the on thedriver's side B-pillar (the structural mem-ber at the side of the vehicle, at the rearof the driver's door opening). Use the airrelease valve to release some air from thetire if necessary.
17. Switch off the compressor and disconnect the electrical wire from the 12-volt socket. Unscrew the hose from the tire

WARNING
•After using the tire sealing system, the vehicle should not be driven farther thanapproximately 120 miles (200 km).
• Have the tire inspected by a trained andqualified Volvo service technician as soonas possible to determine if it can be per-manently repaired or must be replaced.
• The vehicle should not be driven fasterthan 50 mph (80 km/h) while using a tirethat has been temporarily repaired withthe tire sealing system.
• After using the tire sealing system, drivecarefully and avoid abrupt steeringmaneuvers and sudden stops.

Inflating a tire with the tire sealing system compressor
The compressor can be used to inflate a tire.
1. The compressor should be switched off. Ensure that the on/off switch is in position 0.
Take out the electrical wire and hose.
2. Be sure the air release valve on the com- pressor's hose is completely closed. Remove the valve cap from the tire

Refilling coolant
Coolant helps keep the gasoline engine at the proper operating temperature. The heat transfer-red from the engine to the coolant can be usedto warm the passenger compartment.
When refilling coolant, follow the instructions on the package and use the recommended amountof coolant. Never fill the cooling system withwater only; this could lead to freezing, corrosionand engine damage.
WARNING
If the engine has been running, the coolant will be very hot. Allow the engine to coolbefore opening the coolant expansion tank. Ifthis is not possible, open the cap very slowlyto allow pressure to dissipate.
Lift the rubber strip by pressing it inward in the engine compartment.
Remove the plastic cover by folding out the catch and lifting the cover upward.
Remove the expansion tank and add coolant. The level should be between the MIN and
MAX marks on the tank.
Put the other components back in place in the reverse order.
