312 WHAT TO DO IN EMERGENCIES Attach the wheel wrench to the extension tube. Rotate the winch mechanism until the wheel is drawn into place against the underside of the vehicle. Continue to rotate until you feel the winch mechanism slip or click 3 or 4 times. It cannot be overtightened. Push against the tire several times to be sure it is firmly in place. HOISTING A conventional floor jack may be used at the jacking locations, refer to the graphics that show jacking locations. However, a floor jack or frame hoist must never be used on any other parts or the underbody. JUMP-STARTING You should not try to start your vehicle by pushing or towing. Vehicles equipped with an automatic transmission cannot be started this way and pushing or towing a vehicle equipped with a manual transmission may overheat and damage the catalytic converter. Also, there is a greater risk of an accident when a vehicle is being pushed or towed. If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improperly, so follow this procedure carefully. CAUTION! Never use a floor jack directly under the differential housing of a loaded truck or damage to your vehicle may result.
