7. Raise the tire fully against the underside of the vehicle. Continue turning the wheel wrench until you feel more than two clicks. This indicates that the compact spare tire is secure and the cable is tight. The spare tire hoist cannot be overtightened. Compact Spare Tire Although the compact spare tire was fully inflated when the vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on the vehicle, you should stop as soon as possible and make sure the spare tire is correctly inflated. The compact spare is made to perform well at speeds up to 65 mph (105 km/h) for distances up to 3,000 miles (5 000 km), so you can finish your trip and have the full-size tire repaired or replaced where you want. You must calibrate the tire inflation monitor system after installing or removing the compact spare. See Tire Pressure Monitor System on page 5-59. The system may not work correctly when the compact spare is installed on the vehicle. Of course, it's best to replace the spare with a full-size tire as soon as you can. The spare will last longer and be in good shape in case you need it again. Notice: When the compact spare is installed, do not take the vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails which can damage the tire, wheel and other parts of the vehicle. Do not use the compact spare on other vehicles. 8. Make sure the tire is stored securely. Push, pull (A), and then try to turn the tire (B). If the tire moves, use the wheel wrench to tighten the cable. Put back all tools as they were stored in the rear storage compartment and put the compartment cover back on. 5-88
