towed using cables or chains secured to the emergency towing eyelets. This
should only be attempted on hard surfaced roads for short distances at under
5 km/h (3 mph).
A driver must be in the vehicle to steer and operate the brakes. The vehicle’s
wheels, drive train, axles, steering and brakes must be in good condition.Take out the towing eyelet. ( →P. 5 1 8 , 5 2 9 )
Remove the eyelet cover using a flathead screwdriver.
To protect the bodywork, place a rag between the screwdriver and the vehicle body
as shown in the illustration.

WA R N I N G
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When towing the vehicle
■While towing
●When towing using cables or chains, avoid sudden starts, etc. which place excessive
stress on the towing eyelets, cables or chains. The towing eyelets, cables or chains
may become damaged, broken debris may hit people, and cause serious damage.
●Do not turn the power switch off.
There is a possibility that the steering wh eel is locked and cannot be operated.
■Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.
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 power switch is off. The steering lock
mechanism is not strong enough to hold the front wheels straight.
●When raising the vehicle, ensure adequate ground clearance for towing at the oppo-
site end of the raised vehicle. Without adequate clearance, the vehicle could be dam-
aged 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.
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
drivetrain and related parts may be damaged,
an accident may occur due to a change in
direction of the vehicle or electricity generated
by the operation of the motor may cause a fire
to occur depending on the nature of the dam-
age or malfunction.
