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 (1.8L 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.

5-2. Steps to take in an emergency
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
