When trouble arises
NOTICE
■Towing with a sling-type truck

the opposite end of the raised vehicle. Without adequate cleara nce, the
vehicle could be damaged while being towed.

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 arou nd the
brakes may be extremely hot. Touching these areas with hands, f eet or
other body parts may result in burns.
● To avoid risk of burst or severe leakage, do not drop or damage the bottle.
Visually inspect the bottle before use. Do not use a bottle wit h shock,
crack, scratch, leakage or any other damage. In such case, imme diately
replace.
● Connect the valve and hose securely with the wheel installed to the vehi-
cle. If the hose is not properly connected to the valve, air le akage may
occur and 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 completed, 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 fol-
lowed, the sealant may spray out.
● Keep back from the tire while it is being repaired, as there is a chance of it
bursting while the repair operation is being performed. If you notice any
cracks or deformation of the tire, turn off (type A) or (off) (type B) the
compressor switch and stop the repair operation immediately.
● The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 40 minutes.
● Parts of the repair kit become hot during operation. Be careful when han-
dling the repair kit during and after operation. Do not touch t he metal part
around the connecting area between the bottle and the compresso r. I t w il l
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 S RS airbag is
located, such as the pad of the steering wheel, it may prevent the SRS
airbag from operating properly.

■ Charging the 12-volt battery
The electricity stored in the 12- volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the dra ining effects of
certain electrical appliances. If the vehicle is left for a lon g time, the 12-volt
battery may discharge, and the hybrid system may be unable to s tart. (The
