u GENERAL SERVICE INFORMATION TIEDOWN HOOK - FRONT /'-- TIEDOWN HOOK - REAR -?-A TOWING Proper towing equipments are necessary to prevent damage to the vehicle during any towing operation. Laws and regulations applicable to vehicles in tow must always be observed. Release the parking brake, place the shift lever in neutral, and set the ignition switch in the ACC posi- tion. As a rule, towed vehicles should be pulled with the driving wheels off the ground. 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 a towing dolly. CAUTION The power assist for the brakes and steering are inoperable while the engine is off. Do not use the tiedown hooks under the front or rear of the vehicle for towing. These hooks are designed ONLY for transport tiedown. If the tiedown hooks are used for towing, the front or rear skirt and bumper will be damaged.
