Towing the Vehicle
Notice: To avoid damage, the disabled vehicle should be towed with all four wheels off the ground. Care must be taken with vehicles that have low ground clearance and/or special equipment. Always flatbed on a car carrier.
Consult your dealer or a professional towing service if the disabled vehicle must be towed.
See Roadside Service (U.S. and Canada) or Roadside Service (Mexico).
To tow the vehicle behind another vehicle for recreational purposes, such as behind a motor home, see “Recreational Vehicle Towing” in this section.
