Vehicle Care
If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a level
place. Turn on the hazard warning flashers.
See Hazard Warning Flashers 0 125.
See If a Tire Goes Flat 0 332 for other
important safety warnings.
1. Remove the compressor from its storage
location. See Storing the Tire Sealant and
Compressor Kit 0 338.
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 89.
If the vehicle has an accessory power
outlet, do not use the cigarette lighter.
