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 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 ”How to start the engine”
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 ”Keys (with engine immobiliser sys-
tem)” in Chapter 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” 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. 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 ”(b) Starting a flooded
engine” for further instructions.
If your vehicle will not start—

Connecting point
Do not connect the cable to or near
any part that moves when the engine
is cranked.
CAUTION
When making the connections, to
avoid serious injury, do not lean over
the battery or accidentally let the
jumper cables or clamps touch any-
thing except the correct battery termi-
nals 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
pedal 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
cloths—they may now contain sulfuric
acid.
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...
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
vehicle will not start”.
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.

Checking the engine oil level
Low level Full level
Add oil Too fullO.K.
With the engine at operating tempera-
ture and turned off, check the oil level
on the dipstick.
1. To get a true reading, the vehicle
should be on a level spot. After turning
off the engine, wait a few minutes for
the oil to drain back into the bottom of
the engine.
2. Pull out the dipstick, and wipe it clean
with a rag.
3. Reinsert the dipstick—push it in as far
as it will go, or the reading will not be
correct.
4. Pull the dipstick out and look at the oil
level on the end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.
If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine.
Remove the oil filler cap and add engine
oil in small quantities at a time, checking
the dipstick.
The approximate quantity of oil needed to
fill between the low level and the full level
on the dipstick is indicated below for ref-
erence.
When the level reaches within the correct
range, install the filler cap hand−tight.
Oil quantity, L (qt., lmp. qt.):
1.5 (1.6, 1.3)
NOTICE
Avoid overfilling, or the engine
could be damaged.
Check the oil level on the dipstick
once again after adding the oil.

Checking brake fluid
To check the fluid level, simply look at
the see−through reservoir. The level
should be between the ”MAX” and
”MIN” lines on the reservoir.
It is normal for the brake fluid level to go
down slightly as the brake pads wear. So
be sure to keep the reservoir filled.
If the reservoir needs frequent refilling, it
may indicate a serious mechanical prob-
lem.
If the level is low, add SAE J1703 or
FMVSS No. 116 DOT 3 brake fluid to
the brake reservoir.
Remove and replace the reservoir cover
by hand.Use only newly opened brake fluid. Once
opened, brake fluid absorbs moisture from
the air, and excess moisture can cause a
dangerous loss of braking.
CAUTION
Take care when filling the reservoir
because brake fluid can harm your
eyes and damage painted surfaces. If
fluid gets in your eyes, flush your
eyes with clean water.
NOTICE
If you spill some of the fluid, be sure
to wash it off with water to prevent
it from damaging the parts or paint.

mission fluid DEXRONII or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (60C—80C or 140F—175F). You
may also check the level when the fluid
is cold (about room temperature,
10C—30C or 50F—85F) if the engine
has not been run for about five hours.

—Checking battery exterior
Ground cable
Hold−down
clampTerminals
Check the battery for corroded or loose
terminal connections, cracks, or loose
hold−down clamp.
a. If the battery is corroded, wash it off
with a solution of warm water and baking
soda. Coat the outside of the terminals
with grease to prevent further corrosion.
b. If the terminal connections are loose,
tighten their clamp nuts—but do not over-
tighten.
c. Tighten the hold−down clamp only
enough to keep the battery firmly in place.
Overtightening may damage the battery
case.
NOTICE
Be sure the engine and all accesso-
ries are off before performing main-
tenance.
When checking the battery, remove
the ground cable from the negative
terminal (”−” mark) first and rein-
stall it last.
Be careful not to cause a short cir-
cuit with tools.
Take care no solution gets into the
battery when washing it.

Battery recharging precautions
During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed
on the vehicle, be sure to disconnect
the ground cable.
2. Be sure the power switch on the re-
charger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (5 A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.

If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See ”Fuse locations” in Chapter 7−1 for
locations of the fuses.
Turn the ignition switch and inoperative
component off. Pull a suspected fuse
straight out and check it.
Determine which fuse may be causing the
problem. The lid of the fuse box shows
the name of the circuit for each fuse. See
