TOWING TIEDOWN HOOKS - FRONT /-- TIEDOWN HOOKS - REAR - TOWING Proper towing equipment is necessary to prevent dam- age to the vehicle. Laws and regulations applicable to vehicles in tow must always be observed. As a general rule, towed vehicles should be pulled with the driving wheels off the ground. If excessive damage or other conditions prevent towing the vehicle with the driving wheels off the ground, use wheel dollies. With either automatic or manual transmission. 1. Set the ignition switch in the ACC position; 2. Place the selector lever or shift lever in N (Neutral); 3. Release the parking brake. With manual transmission If the transmission, rear axle, and steering system are not damaged, the vehicle may be towed on all four wheels. If any of these components are damaged, use wheel dollies. With automatic transmission If excessive damage or other conditions prevent towing the vehicle with the driving wheels off the ground, use wheel dollies. If all four wheels are on the ground, the vehicle may be towed only forward. Don't exceed 56 kmlh {35 mph} and a distance of 56 km (35 miles); you could damage the transmission. If speed must exceed 56 kmlh (35 mph} or a towing dis- tance of 56 km (35 miles}, use one of these methods: Place the rear wheels on a dolly; Tow with the rear wheels off the ground; Disconnect the propeller shaft. If the transmission or rear axle is inoperative, two with the rear wheels off the ground. Caution Don't tow with sling-type equipment. This could damage your vehicle. Use wheel-lift or flatbed equipment. Caution Don't use the hook loops under the front for tow- ing. They are designed ONLY for tying down the vehicle when it's being transported. Using them for towing will damage the bumper. GI-I 9 Gartner Banana
