Towing with a wheel-lift
type truck

WARNING

Observe the following precau-

tions.

Failure to do so may result in

death or serious injury.

312

7-2. Steps to take in an emergency

When using a flat-bed truck to
transport the vehicle, use tire
strapping belts. Refer to the
owner's manual of the flat-bed
truck for the tire strapping
method.
In order to suppress vehicle
movement during transporta-
tion, set the parking brake and
turn the engine switch off.

If a tow truck is not available in
an emergency, your vehicle may
be temporarily towed using
cables or chains secured to the
emergency towing eyelets. This
should only be attempted on
hard surfaced roads for at most
50 miles (80 km) at under 18
mph (30 km/h).
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.

WARNING

■

When towing the vehicle

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 or related

parts may be damaged, the vehi-

cle may fly off the truck.

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 engine switch is

off. The steering lock mecha-

nism is not strong enough to

hold the front wheels straight.

●

When raising the vehicle,

ensure adequate ground clear-

ance for towing at the opposite

end of the raised vehicle. With-

out adequate clearance, the

vehicle could be damaged while

being towed.
