Inspect the tires to check if a tire is punctured.
If a tire is punctured: →P. 524
If none of the tires are punctured:
Turn the engine switch off then turn it to IGNITION ON mode. Check if the
tire pressure warning light comes on or flashes.
If the tire pressure warning light comes on
After the temperature of the tires has lowered sufficiently, check the
inflation pressure of each tire and adjust them to the specified level.
If the warning light does not turn off even after several minutes have
elapsed, check that the inflation pressure of each tire is at the specified
level and perform initialization. (→P. 464)
If the warning light does not turn off even after several minutes have
elapsed, have the vehicle inspected by your Toyota dealer immediately.
If the tire pressure warning light flashes for 1 minute then stay on
There may be a malfunction in the tire pressure warning system. Have
the vehicle inspected by your Toyota dealer immediately.
■The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such as
natural air leaks or tire inflation pressure changes caused by tempera-
ture. In this case, adjusting the tire inflation pressure will turn off the warn-
ing light (after a few minutes).
■When a tire is replaced with a spare tire
The spare tire is also equipped with the tire pressure warning valve and
transmitter. The tire pres sure warning light will turn on if the tire inflation
pressure of the spare tire is low. If a tire goes flat, even though the flat tire
is replaced with the spare tire, the tire pressure warning light does not
turn off. Replace the spare tire with the repaired tire and adjust the proper
tire inflation pressure. The tire pres sure warning light will turn off after a
few minutes.

Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the batter y of your vehicle.
Open and close any of the doors with the engine switch off.
Maintain the engine speed of the second vehicle and start your
vehicle’s engine.
Once the vehicle’s engine has star ted, remove the jumper cables in
the exact reverse order in which they were connected.
Once the engine starts, have the vehicle checked at your Toyota
dealer as soon as possible.
■ Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ Avoiding a discharged battery
●Turn off the headlights and the audio system while the engine 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, etc.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
WARNING
■ Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery.
● Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended termi-
nal.
● Do not allow the jumper cables to come into contact with the “+” and “-” ter-
minals.
● Do not allow open flame or use matches, cigarette lighters or smoke near
the battery.
