Failure to do so may result in death or
serious injury. ■
When towing the vehicle
2WD models
Be sure to transport the vehicle with all
four wheels raised off the ground. If the
vehicle is towed with the tires contacting
the ground, the driv etrain and related
parts may be damaged or an accident
may occur due to a change in direction
of the vehicle.
