Removing the Flat Tire and Installing the Spare Tire 1. If there is 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. If your vehicle has aluminum wheels, remove the wheel nut caps using the wheel wrench. 2. Loosen the wheel nuts - but do not remove them - using the folding wrench. Turn the handle about 180 degrees, then flip the handle back to the starting position. This avoids taking the wrench off the lug nut for each turn. Notice: If your vehicle has wheel locks and you use an impact wrench to remove the wheel nuts, you could damage the lock nut or wheel lock key. Do not use an impact wrench to remove the wheel nuts if your vehicle has wheel locks. 3. Locate the notch (A is 3.0 inches (7.5 cm) from the front tire or B is 5.5 inches (14.0 cm) from the rear tire). The notch is located near each wheel in the vehicle's body. For wheels with a wheel lock key, use the wheel lock key between the lock nut and folding wrench. The key is supplied in the front passenger door pocket. 5-80 Notice: If you use a jack to raise the vehicle without positioning it correctly, you could damage your vehicle. When raising your vehicle on a jack, avoid contact with the rear axle control arms. Do not raise the vehicle yet. Put the compact spare tire near you.
