Removing the Wheel Covers If the wheel has a center cap, use the handle of the folding wrench to pry it off. Then, with the other end of the folding wrench, loosen the nuts. Removing the Flat Tire and Installing the Spare Tire 1. 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. If your vehicle has the plastic bolt-on wheel covers, loosen the bolts completely using the folding wrench, and remove the wheel cover. 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. 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. 5-83
