■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and explosive. Therefore, observe the fol-
lowing precautions before recharging:
●If recharging with the battery installed
on the vehicle, be sure to disconnect the ground cable.
●Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.
■After recharging/reconnecting the battery (vehicles with a smart entry
& start system)
●Unlocking the doors using the smart
entry & start system may not be possi- ble immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
●Start the engine with the engine switch in ACC. The engine may not start with the engine switch turned off.
However, the engine will operate nor- mally from the second attempt.
●The engine switch mode is recorded by the vehicle. If the battery is recon-nected, the vehicle will return the
engine switch mode to the status it
was in before the battery was discon- nected. Make sure to turn off the engine before disconnecting the bat-
tery. Take extra care when connecting the battery if the engine switch mode prior to discharge is unknown.
If the system will not start even after
multiple attempts, contact any autho-
rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.

replaced, make sure to tell any autho-
rized Toyota retailer or Toyota autho- rized repairer, or any reliable repairer that the sealant is injected.
■If the tire is inflated to more than the specified air pressure
1 Press the button to let some air out.
2 Check that the air pressure indicator
shows the specified air pressure. If
the air pressure is under the desig-
nated pressure, turn the compres-
sor switch (on) again and repeat
the inflation procedure until the
specified air pressure is reached.
■The valve of a tire that has been repaired
After a tire is repaired with the emer-
gency tire puncture repair kit, the valve should be replaced.
■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 pres-
sure warning light may come on/flash.
WARNING
■Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire. Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair.
Driving with a flat tire may cause a cir- cumferential groove on the side wall.
In such a case, the tire may explode when using a repair kit.
■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 sealant may spray out.
