NOTICE
■To prevent causing serious damage to the transmission and transfer
(4WD models) when towing using a wheel-lift type truck
2WD models: Never tow this vehicle from the front with the rear wheels on
the ground.

for towing at the opposite end of the raised vehicle. Without adequate
clearance, the vehicle could be damaged while being towed from the rear.

Do not tow with a sling-type truck, either from the front or rear.
■ To prevent causing serious damage to the transmission and transfer in
emergency towing (4WD models)

cause serious damage to the transmission and transfer.
■ Emergency towing eyelet precautions
● Before emergency towing, check that the eyelet is not broken or damaged
and that the installation bolts are not loose.
● Fasten the towing cable or chain securely to the eyelet.
● Do not jerk the eyelet. Apply steady and even force.
