Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a flat tire. Check the tires.
If the tire is flat, temporary repair it with liquid sealants and have the
flat tire repaired or replaced by the nearest Scion dealer as soon as
possible.

306 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.
■ 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.)
CAUTION
■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 smoke, use matches, cigarette lighters or allow open flame near
the battery.
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 Scion
dealer as soon as possible.

or comes on, and engine output falls (There is no speed).
● Steam is coming out from the engine compartment.
Perform the following steps.

system, and stop the engine.
If steam is coming out:
When no more steam is coming out has been confirmed,
carefully open the hood.
If there is no steam coming out:
Carefully open the hood. After the engine has cooled
down sufficiently, inspect the
radiator core (radiator), hoses,
etc. for any leaks.
If there is a large quantity of
engine coolant leaking, imme-
diately contact your Scion
dealer.
Inspect the amount of engine
coolant by checking if the res-
ervoir level is between FULL
and LOW lines.
