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.) 2. Near each wheel, there is a notch in the vehicle's body. Position the jack and raise the jack head until it fits firmly into the notch in the vehicle's frame nearest the flat tire. 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: Do not place the jack under the rear axle control arms or you may damage your vehicle. Only use the areas shown for proper jack location. Do not raise the vehicle yet. Put the compact spare tire near you. Notice: To help avoid damage to lock nut or wheel lock key, donot use an impact wrench with this key. 5-76
