■If the tire is inflated to more than the recommended level
Disconnect the hose from the valve.
Disconnect the hose from the valve, remove the air release cap from the hose and then reconnect the hose.
Turn the compressor switch on and wait for several seconds, then turn it off. Check that the air pressure indicator sh ows the recommended level. (P. 604) If the air pressure is lower than the reco mmended level, turn the compressor switch on
again and repeat the inflation procedure un til the recommended pressure is reached.
■After a tire is repaired with the emergency tire puncture repair kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire pressure warning light may come on/flash.
■Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally. The expiry date is shown on the bottle. Do not use sealant whose expiry date has alreadypassed. Otherwise, repairs conducted using th e emergency tire puncture repair kit may

WARNING
■When fixing the flat tire
Observe the following precautions. Failure to do so may result in death or serious injury.
●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 inburns.
●Connect the valve and hose securely with the tire installed on the vehicle.
• If the hose is not properly connected to the valve, air leakage may occur or 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 procedure is not followed, 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 performe d. If you notice any cracks or deforma-
tion of the tire, turn off the compressor sw itch and stop the repair operation immedi- ately.
●The kit may overheat if operated for a long period of time. Do not operate the com-
pressor continuously for more than 35 minutes.
●Parts of the kit become hot during operatio n. Be careful handling the kit during and after operation. Do not touch the metal part around the connecting area between the
bottle and compressor. It will be extremely hot.
●Do not attach the vehicle speed warning sticker to an area other than the one indi- cated. If the sticker is attached to an area where an SRS airbag is located, such as the
pad of the steering wheel, it may preven t the SRS airbag from operating properly.
■Driving to spread the liquid sealant evenly
●Drive the vehicle carefully at a low speed. Be especially careful when turning and cor-
nering.
●If the vehicle does not drive straight or you feel a pull through the steering wheel, stop the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel. • Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/cm2 or b ar, 1 9 p si)or below, this may indica te severe tire damage.

■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is off.
●Turn off any unnecessary electrical components when the vehicle is running at a low
speed for an extended period, such as in heavy traffic.
■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 draining effects of certain electrical appli- ances. If the vehicle is left for a long time, the 12-volt battery may discharge, and thehybrid system may be unable to start. (The 12-volt battery recharges automatically while
the hybrid system is operating.)
■When recharging or replacing the 12-volt battery
●In some cases, it may not be possible to unlock the doors using the smart entry & start
system when the 12-volt battery is discharg ed. Use the wireless remote control or the mechanical key to lock or unlock the doors.
●The hybrid system may not start on the first attempt after the 12-volt battery has
recharged but will start normally after the second attempt. This is not a malfunction.
●The power switch mode is memorized by the vehicle. When the 12-volt battery is reconnected, the system will return to the mod e it was in before the 12-volt battery was
discharged. Before disconnecting the 12-v olt battery, turn the power switch off. If you are unsure what mode the power switch was in before the 12-volt battery dis-charged, be especially careful when reconnecting the 12-volt battery.
