running and make sure the electric
cooling fan is operating. If it is not,
turn the ignition off.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.

Before making these checks, make sure
you have followed the correct starting
procedure given in How to start the
engine" on page 124 in Section 3 and that
you have sufficient fuel. Also check
whether the other keys will start the
engine. If they work, your key may be
broken. Have the key checked at your
Toyota dealer. If none of your keys work,
the engine immobiliser system is possibly
broken. Call your Toyota dealer. (See
Keys" on page 8 in Section 1−2.)
If the engine is not turning over or is
turning over too slowly1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked, the battery
is discharged. You may try jump start-
ing. See (c) Jump starting" on page
151 for further instructions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair
shop.NOTICE
Do not pull− or push−start the ve-
hicle. It may damage the vehicle or
cause a collision when the engine
starts. Also the three−way catalytic
converter may overheat and become a
fire hazard.
If the engine turns over at its normal
speed but will not start
1. The engine may be flooded because of repeated cranking. See (b) Starting a
flooded engine" on page 150 for further
instructions.
2. If the engine still will not start, it needs adjustment or repair. Call a Toyota
dealer or qualified repair shop.
(b) Starting a flooded engine
If the engine will not start, your engine
may be flooded because of repeated
cranking.
If this happens, turn the key to START"
with the accelerator pedal held down.
Keep the key and accelerator pedal in
these positions for 15 seconds and re-
lease them. Then try starting the engine
with your foot off the accelerator pedal.
If the engine does not start after 15 sec-
onds of cranking, release the key, wait a
few minutes and try again.
If the engine still will not start, it needs
adjustment or repair. Call a Toyota dealer
or qualified repair shop for assistance.
