(3) Even in case of a minor collision where the SRS
does not deploy, the steering wheel pad, the pas-
senger airbag assembly, side airbag assembly, cur-
tain shield airbag assembly, seat belt pretensioner,
airbag sensor assembly, front airbag sensor, side
airbag sensor assembly and curtain shield airbag
sensor assembly should be inspected.

(4) Never use SRS parts from another vehicle. When
replacing parts, replace them with new ones.
(5) Before repairs, remove the airbag sensor because
shocks are likely to be applied to the sensor during
repairs.
(6) Never disassemble or repair the steering wheel
pad, front passenger airbag assembly, airbag sen-
sor assembly and front airbag sensor.
(7) If the steering wheel pad, front passenger airbag
assembly, side airbag assembly, curtain shield air-
bag assembly, seat belt pretensioner, airbag sensor
assembly and front airbag sensor have been
dropped, or if there are cracks, dents or other de-
fects in the case, bracket or connector, replace
them with new ones.
(8) Do not expose the steering wheel pad, front pas-
senger airbag assembly, side airbag assembly, cur-
tain shield airbag assembly, seat belt pretensioner,
airbag sensor assembly and front airbag sensor di-
rectly to hot air or flames.
(9) Use a volt/ohmmeter with high impedance (10 kW/V
minimum) for troubleshooting of the electrical cir-
cuit.
(10) Information labels are attached to the periphery of
the SRS components. Follow the instructions on the
notices.
(11) After work on the supplemental restraint system is
completed, check the SRS warning light (See page
DI±1118).

GENERAL MAINTENANCE
1. GENERAL NOTES

Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.

Every service item in the periodic maintenance schedule must be performed.

Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).

Maintenance service after the last period should be performed at the same interval as before unless
otherwise noted.

Failure to do even one item can cause the engine to run poorly and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the FULL and LOW lines on the see±through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(2UZ±FE engine: See page CO±14)
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells is between the upper and lower level lines on the case.
6. BRAKE AND CLUTCH FLUID LEVELS
Check that the brake and clutch fluid levels are near the upper level line on the see±through reservoirs.
7. ENGINE DRIVE BELTS
Check all drive belts for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL
(a) Check the level on the dipstick.
(b) The level should be in the HOT or COLD range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking brake applied, shift the selector into all positions from the P to
L, and then shift into the P position.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re±insert the dipstick and check that the
fluid level is in the HOT range.
(d) Do this check with the fluid at normal driving temperature (70 ± 80°C, 158 ± 176°F).
HINT:
Wait until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at
high speeds, in hot weather, in heavy traffic or pulling a trailer.
11. EXHAUST SYSTEM
(a) Visually inspect for cracks, holes or loose supports.
(b) If any change in the sound of the exhaust or smell of the exhaust fumes is noticed, find the cause and
correct.
