in death or serious injury.
■When towing the vehicle
Be sure to transport the vehicle
with the front wheels raised or
with all four wheels raised off the
ground. If the vehicle is towed
with the front wheels contacting
the ground, the drivetrain and

tion of the motor may cause a fire
to occur depending on the nature
of the damage or malfunction.

serious injury:
• Unfasten the driver’s seat belt and open the driver’s door.
• Turn the power switch off.
