Part 4
IN CASE OF AN
EMERGENCY
If your vehicle will not start
If your engine stalls while
driving
If your vehicle overheats
If you have a flat tire
If your vehicle needs to be
towed
If you cannot shift automatic
transmission selector lever
If you lose your keys
If you lose your wireless remote
control transmitter
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in ºHow to start the engineº
in Part 3 and that you have sufficient fuel.
If your vehicle is equipped with the engine
immobiliser system, 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 system is
possibly broken. Call your Toyota dealer.
(See ºKeys (with engine immobiliser sys-
tem)º in Chapter 1±2.)
If the engine is not turning over or is
turning over too slowlyÐ
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 º(c) Jump startingº 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 startÐ
1. Check that all the push±on connectors
are tight. (For example, connectors at
the spark plugs, ignition coil and/or dis-
tributor)
2. If the connectors are O.K., the engine
may be flooded because of repeated
cranking. See º(b) Starting a flooded
engineº for further instructions.
If your vehicle will not startÐ

The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.
