If Your Vehicle Will Not Start - Toyota Sienna 2004 Operating Manual

If your vehicle will not start—

(a) Simple checks
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in "How to start the engine"
on page 380 in Section 3 and that you
have sufficient fuel. If your vehicle is
equipped with the engine immobiliser sys-
tem, also check whether the other keys
will start the engine. If they work, your
key may be broken. Have the
checked at your Toyota dealer. If none of
your keys work, the system is possibly
broken. Call your Toyota dealer. (See
"Keys (with engine immobiliser system)"
on page 10 in Section 1- 2.)
If the engine is not turning over or is
turning over too slowly—
1. 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
393 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.

tions.

(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 these
positions for 15 seconds and release
them. Then try starting the engine with
your foot off the accelerator pedal.
If the engine does not start after 15 se-
conds 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.
NOTICE
Do not crank for more than 30 se-
conds at a time. This may overheat
the starter and wiring systems.
