wheel-lift type truck or flat-
bed truck.

Use a safety chain system
for all towing, and abide by
all state/provincial and local

■

When towing the vehicle

2WD models: Be sure to transport

the vehicle with the front wheels

raised or with all four wheels

raised off the ground. If the vehi-

cle is towed with the front wheels

contacting the ground, the drive-

train and related parts may be

damaged or electricity generated

by the operation of the motor may

cause a fire to occur depending

on the nature of the damage or

malfunction.

the vehicle with all four wheels

raised off the ground. If the vehi-

cle is towed with the tires contact-

ing the ground, the drivetrain or

tion of the motor may cause a fire

to occur depending on the nature

of the damage or malfunction.
