Emergency towing
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 a short distance 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.
Emergency towing procedure
1
Take out the towing eyelet. (P. 507)

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

■While towing
If the hybrid system is off, the power assist for the brakes and steering will not
function, making steering and braking more difficult.

WARNING
Observe the following precautions.
Failure to do so may result 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 related
parts may be damaged or electricity gen-
erated by the operation of the motor may
cause a fire to occur depending on the
nature of the damage or malfunction.
■While towing
●When towing using cables or chains, avoid sudden starts, etc. which place
8
excessive stress on the towing eyelet, cables or chains. The towing eyelet,
cables or chains may become damaged, broken debris may hit people and
cause serious damage.
● Do not turn the power switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.
■ Installing towing eyelets to the vehicle
● The towing eyelets are only for the vehicle equipped with them. Do not use
the towing eyelets for another vehicle, and do not use the towing eyelets
for this vehicle on another vehicle.
●Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.
