(j) SRS Warning Light
This light will come on when the igni-
tion key is turned to the ACCº or
ONº position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as

If your vehicle overheats
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in Pº
(automatic) or neutral (manual) and ap-
ply the parking brake. Turn off the air
conditioning if it is being used.
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.
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.
3. Visually check to see if the enginedrive 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 conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or thecoolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as-
sistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the
engine is running. Fill it about half full.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. After the engine coolant temperaturehas cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You s hould have it checked as
soon as possible at your Toyota dealer.

Make sure the coolant level is between
the Fº and Lº lines on the see- through
reservoir when the engine is cold. See
Chapter 7- 2 for additional information.Battery electrolyte level
Make sure the electrolyte level of all bat-
tery cells is between upper and lower lev-
el lines on the case. Add only distilled
water when replenishing. See Chapter 7- 3
for additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See Chapter 7- 2 for additional information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level spot. See Chapter 7- 2 for addi-
tional information.
Power steering fluid level (5VZ- FE en-
gine)
Check the level on the dipstick. The level
should be in the HOTº or COLDº range
depending on the fluid temperature. See
Chapter 7- 2 for additional information.
Power steering fluid level (2UZ- FE en-
gine)
Check the level through the reservoir. The
level should be in the HOTº or COLDº
range depending on the fluid temperature.
See Chapter 7- 2 for additional information.Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See engine exhaust cautions in

NOTICE

Remember that battery and ignitioncables carry high currents or volt-ages. Be careful of accidentallycausing a short circuit.

Add only demineralized or distilledwater to fill the radiator. And if youspill some of the coolant, be sure
to wash it off with water to preventit from damaging the parts or paint.

Do not allow dirt or anything elseto fall through the spark plug holes.

Do not pry the outer electrode of a
spark plug against the center elec-trode.

Use only spark plugs of the speci-fied type. Using other types willcause engine damage, loss of per-
formance or radio noise.

Do not overfill automatic transmis-sion fluid, or the transmissioncould be damaged.

Do not drive with the air cleaner
filter removed, or excessive enginewear could result. Also backfiringcould cause a fire in the engine
compartment.

Be careful not to scratch the glasssurface with the wiper frame.

When closing the engine hood,check to see that you have not for-
gotten any tools, rags, etc.

Checking brake fluid
To check the fluid level, simply look at
the see- through reservoir. The level
should be between the MAXº and
MINº 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. Fill the brake fluid to the dotted
line. This brings the fluid to the correct
level when you put the cover back on.
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 r
eservoir
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 the fluid, be sure to wash it off with water to prevent it fromdamaging the parts or paint.
If cold add
If cold O.K.
If hot add If hot O.K.
Check the fluid level on the dipstick. If
necessary, add automatic transmission
fluid DEXRON II 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 (40 5CÐ80 5C or 104 5FÐ175 5F). You
may also check the level when the fluid
is cold (about room temperature,
0 5CÐ40 5C or 32 5FÐ104 5F) if the engine
has not been run for about five hours.
a. Clean all dirt from outside of the reser-
voir tank.
b. Remove the filler cap by turning it
counterclockwise and wipe the dipstick
clean.

c. Reinstall the filler cap.
d. Remove the filler cap again and look at
the fluid level. If the fluid is cold, the
level should be in the COLDº range on
the dipstick. Similarly, if it is hot, the fluid
level should be in the HOTº range. If the
level is at the low side of either range,
add automatic transmission fluid
DEXRONII or III to bring the level within
the range.
e. After replacing the filler cap, visually
check the steering box case, vane pump
and hose connections for leaks or dam-
age.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.

Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRON II 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 (60 CÐ80 C or 140 FÐ175 F). You
may also check the level when the fluid
is cold (about room temperature,
10 CÐ30 C or 50 FÐ85 F) if the engine
has not been run for about five hours. Clean all dirt from outside of the reservoir
tank and look at the fluid level. If the fluid
is cold, the level should be in the COLDº
range. Similarly, if it is hot, the fluid level
should be in the HOTº range. If the level
is at the low side of either range, add
automatic transmission fluid DEXRON
II
or III to bring the level within the range.
To remove the filler cap, turn it c ounter-
clockwise and lift up. To reinstall it, turn
it clockwise. After replacing the filler cap,
visually check the steering box case, vane
pump and hose connections for leaks or
damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
