NOTICE
■
To prevent damage to the vehicle
Do not pull- or push-start the vehicle, because the catalytic converter may
overheat and become a fire hazard.
■ When handling jumper cables
Be careful that the jumper cables do not become tangled in the cooling fans
or any of the belts when connecting or disconnecting them.
■ When attaching the engine cover (1 .8 L 4-cylinder [2ZR-FE] engine)
Ensure that the rubber grommets remain attached to the engine cover. If the
grommet is attached to the bolts, transfer grommets to the engine cover.

If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the air condi-
tioning system.
Check to see if steam is coming out from under the hood.
If you see steam: Stop the engine. Carefully lift the hood after the steam
subsides and then restart the engine.
If you do not see steam: Leave the engine running and carefully lift the hood.
Check to see if the cooling fans are operating.
If the fans are operating: Wait until the temperature of the engine (shown on the
instrument cluster) begins to fall and then stop the
engine.
If the fans are not operating: Stop the engine and call your Toyota dealer.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.STEP 1
