4708-2. Steps to take in an emergency
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 hooks. This should only be attempted on hard surfaced roads
for at most 50 miles (80 km) at under 18 mph (30km/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.
Securely attach cables or chains to the towing hooks.
Take care not to damage the vehicle body.
Enter the vehicle being towed and start the engine.
If the engine does not start, turn the engine switch to the “ON” position.
4WD models: Put the front-wheel drive control switch in “2WD”.

CAUTION
Observe the following precautions.
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 drivetrain
and related parts may be damaged or an
accident may occur due to a change in
direction of the vehicle.
4WD 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 drivetrain
or related parts may be damaged, the
vehicle may fly off the truck.
■ While towing
● When towing using cables or chains, avoid sudden starts, etc. which
place excessive stress on the towing hooks, cables or chains. The tow-
ing hooks, cables or chains may become damaged, broken debris may
hit people, and cause serious damage.
