When towing the vehicle at faster speeds for greater
distances, the following steps MUST be taken:
• If front wheels are on the road, disconnect the front
drive shaft.
• If rear wheels are on the road, disconnect the rear
drive shaft.
Both 3 and 4 speed transmissions should be towed in
neutral only, with parking brakes fully released.
When towing a vehicle on its front wheels only, the
steering wheel should be secured to maintain a straight
