tire strapping method.
In order to supp ress vehicle move-
ment during transportation, set the
parking brake and turn the power
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 short distances at under 30
km/h (18 mph).
A driver must be i n the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drive train, axles,
steering and brakes must be in
good condition.
To have your vehicle towed by
another vehicle, the towing eyelet
must be installed to your vehicle.
Install the towing eyelet using the
following procedure.

WARNING
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area
around the brakes immediately after the vehicle has been driven.
After the vehicle has been driven,
the wheels and the area around the brakes may be extremely hot.
Touching these areas with hands,
feet or other body parts may result in burns.
●Connect the valve and hose securely with the tire installed on
the vehicle. If the hose is not prop-
erly connected to the valve, air leakage may occur as sealant may
be sprayed out.
●If the hose comes off the valve
while inflating the tire, there is a risk
that the hose will move abruptly due to air pressure.
●After inflation of the tire has com - pleted, the sealant may splatter
when the hose is disconnected or
some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures not
followed, the seal ant may spray
out.
●Keep back from the tire while it is
being repaired, as there is a chance of it bursting while the repair opera -
tion is being performed. If you
notice any cracks or deformation of the tire, turn off the compressor
switch and stop the repair operation
immediately.
●The repair kit may overheat if oper-
ated for a long period of time. Do not operate the repair kit continu -
ously for more than 40 minutes.
●Parts of the repair kit become hot
during operation. Be careful han -
dling the repair kit during and after operation. Do not touch the metal
part connecting the bottle and the
compressor. It will be extremely hot.
●Do not attach the vehicle speed warning sticker to an area other
than the one indicated. If the sticker
is attached to an area where an SRS airbag is located, such as the
pad of the steering wheel, it may
prevent the SRS airbag from oper - ating properly.
■Driving to spread the liquid seal- ant evenly
Observe the following precautions to
reduce the risk of accidents.
Failing to do so may result in a loss of
vehicle control and cause death or
serious injury.
●Drive the vehicle carefully at a low speed. Be especially careful when
turning and cornering.
