Front Towing Hookup
Warning: Do not tow an unbraked vehicle if the combined weight of both vehicles is more than the sum of the gross axle weight ratings (GAWR) of the towing vehicle. Otherwise brake capacity will be inadequate, which could result in personal injury or death.
Important: When it is necessary to tow the vehicle, follow the instructions below closely to prevent damage to the vehicle.
When towing or pushing any vehicle equipped with an Allison transmission, disconnect the driveshaft at the rear axle and support it as necessary, regardless of the distance or speed traveled.
Note: Towing rules and regulations vary from federal, state, local, and transit authority. These laws must be followed when towing the vehicle.
- Disconnect the battery ground cable.
- Remove the bumper.
- Attach the towing device. Due to the many variables that exist in towing, positioning the lifting and towing device is the sole responsibility of the towing-vehicle operator.
- Lift the vehicle and secure the safety towing chains. If additional clearance is needed, remove the front wheels.
- Connect the clearance lights, taillights, and signal lights. Connect any special towing lights required by local regulations.
- Chock the tires on the disabled vehicle and connect the towing vehicle's air brake system to the vehicle being towed. Then, release the spring parking brake and remove the chocks.
- On vehicles equipped with hydraulic disc brakes be sure the parking brake is released before starting the towing process.
Notice: Failure to protect the frame rails from the chains could cause damage, leading to eventual frame failure.
Warning: Before releasing the parking brakes, make the connection to the towing vehicle or chock the tires on the disabled vehicle. Failure to do so could result in hazardous conditions because the vehicle could suddenly roll and injury could occur.
Notice: Before attempting to tow a vehicle with air suspension (and during the towing operation), ensure that the air suspension is properly aired. Air the suspension through the Schrader valve on the air dryer. Attempting to tow a vehicle with an improperly aired suspension may result in damage to the chassis and body.
