10-70 Vehicle Care If the vehicle has aluminum wheels, remove the wheel nut caps using the wheel wrench. Notice: If this vehicle has wheel locks and an impact wrench is used to remove the wheel nuts, the lock nut or wheel lock key could be damaged. Do not use an impact wrench to remove the wheel nuts if this vehicle has wheel locks. 5. If you still cannot lower the spare tire to the ground, see Secondary Latch System on page 10‑77. Removing the Flat Tire and Installing the Spare Tire 1. Do a safety check before proceeding. See If a Tire Goes Flat on page 10‑58 for more information. 2. If the vehicle has a wheel cover, loosen the plastic nut caps with the wheel wrench. They will not come off. Then, using the flat end of the wheel wrench, pry along the edge of the cover until it comes off. Be careful; the edges may be sharp. Do not try to remove the cover with your bare hands. Store the wheel cover securely in the rear of the vehicle until you have the flat tire repaired or replaced. 3. Loosen the wheel nuts - but do not remove them - using the lug wrench. For wheels with a wheel lock key, use the wheel lock key between the lock nut and lug wrench. The key is supplied in the front passenger door pocket. 4. To identify the appropriate jacking location, find the triangle (A) about 12 inches (30.5 cm) from the front tire or (B) about 10.5 inches (27 cm) from the rear tire. The triangle is located near each wheel on the vehicle's exterior.
