cause loss of vehicle control and re sult in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.

ing valve and transmitter, low inflation pressure of the spare tire will not
be warned. Also, if you replace the temporary spare tire after the tire
pressure warning light comes on, the light remains on.

When trouble arises

5-2. Steps to take in an emergency
■
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 turned
off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
■ When the battery is removed or discharged
Flex-fuel vehicles: The information recorded in the computer will be cleared,
which may cause the engine to run roughly and reduce driving performance
for a while when the engine is first started. In this case, wait until the engine
runs normally.
If the vehicle is running on E85, the engine may stall. In this case, restart the
engine, repeatedly if necessary.
■ 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.)
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the engine starts, have the vehicle checked at your Toyota
dealer as soon as possible.
