NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type truck
●Do not tow the vehicle from the rear when the engine switch is off. The steering
lock mechanism is not strong enough to hold the front wheels straight.

opposite end of the raised vehicle. Without adequate clearance, the vehicle
could be damaged while being towed.
■To prevent damage to the vehicle when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
■To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the suspension components.
■Recreational towing (behind motor home, etc.)
Never dinghy tow your vehicle to prevent
causing serious damage to the transfer
(AWD models) and transmission.
