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
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in How to start the engineº
in Part 3 and that you have sufficient fuel.
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 dis-
charged. You may try jump starting. See
(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 vehicle. It may damage the vehicle or
cause a collision when the engine starts. Also the three-way catalyticconverter may overheat and become
a fire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. 2JZ-GE engineÐCheck that all the
push-on connectors are tight. (For exam-
ple, connectors at the distributor and spark plugs)
2. If the connectors are O.K., the engine
may be flooded because of repeated cranking. See (b) Starting a flooded en-
gineº for further instructions.

126Do not connect the cable to or near any
part that moves when the engine is cranked.
NOTICE
When making the connections, do not lean over the battery or
accidentally let the jumper cables or clamps touch anything exceptthe correct battery terminals or the ground.
5. Start your engine in the normal way.
After starting, run it at about 2000 rpm for several minutes with the accelerator ped-
al lightly depressed.
6. Carefully disconnect the cables in the
exact reverse order: the negative cable
and then the positive cable.
7. Carefully dispose of the battery cover
clothsÐthey may now contain sulfuricacid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on), you should have it checked. If your engine stalls while driving
0
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see If your ve-
hicle will not startº.If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual. CAUTION
! If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a
loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure 0
1. Pull safely off the road, stop the vehicle
and turn on your emergency flashers. Put
the transmission in Pº (automatic) or neu-
tral ( manual) and apply the parking brake.
Turn off the air conditioning if it is beingused.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine. Wait
until the steam subsides before opening
the hood. If there is no coolant boiling over or steam, leave the engine running.
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. CAUTION
!
3. Visually check to see if the engine drive
belt (fan belt) is broken or loose. Look for
obvious coolant leaks from the radiator,
hoses, and under the vehicle. However, note that water draining from the air condi-
tioning is normal if it has been used.
