If a tire goes flat, avoid further tire and

place. Turn on the hazard warning flashers.
See Hazard Warning Flashers 0 126.
See If a Tire Goes Flat 0 305 for other
important safety warnings.
1. Remove the compressor from its storage
location. See Storing the Tire Sealant and
Compressor Kit 0 312.
2. Remove the air only hose (8) and the
power plug (7) from the compressor.
3. Place the compressor on the ground near
the flat tire.
Make sure the tire valve stem is
positioned close to the ground so the
hose will reach it.
4. Remove the valve stem cap from the flat
tire by turning it counterclockwise.
5. Attach the air only hose (8) to the tire
valve stem by turning it clockwise until
tight.
6. Plug the power plug (7) into the
accessory power outlet in the vehicle.
Unplug all items from other accessory
power outlets. See Power Outlets 0 91.
If the vehicle has an accessory power
outlet, do not use the cigarette lighter.
If the vehicle only has a cigarette lighter,
use the cigarette lighter.
Do not pinch the power plug cord in the
door or window.
7. Start the vehicle. The vehicle must be
running while using the air compressor.
8. Press the on/off button (4) to turn the
tire sealant and compressor kit on.
The compressor will inflate the tire with
air only.
9. Inflate the tire to the recommended
inflation pressure using the pressure
gauge (6). The recommended inflation
pressure can be found on the Tire and
Loading Information label. See Tire
Pressure 0 294.
The pressure gauge (6) may read higher
than the actual tire pressure while the
compressor is on. Turn the compressor
off to get an accurate pressure reading.
The compressor may be turned on/off
until the correct pressure is reached.
Caution
If the recommended pressure cannot be
reached after approximately 25 minutes,
the vehicle should not be driven farther.
