(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN-8).
Cancel the parking brake on the level place and
shift the transmission in Neutral (or N position).
When jacking up the front wheels of the vehicle at
first place stoppers behind the rear wheels.
When jacking up the rear wheels of the vehicle at
first place stoppers before the front wheels.
When either the front or rear wheels only should be
jacked up, set rigid racks and place stoppers in front
and behind the other wheels on the ground.
After the vehicle is jacked up, be sure to support it
on rigid racks . It is extremely dangerous to do any
work on a vehicle raised on a jack alone, even for
a small job that can be finished quickly.
(l) Observe the following precautions to avoid damage to the
following parts:
(1) Do not open the cover or case of the ECU unless
absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static electric-
ity.)
(2) To disconnect vacuum hoses, pull off the end, not
the middle of the hose.
(3) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(4) Be careful not to drop electrical components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not reused.
(5) When steam cleaning an engine, protect the elec-
tronic components, air filter and emission-related
components from water.
(6) Never use an impact wrench to remove or install
temperature switches or temperature sensors.

INSPECTION
HINT:
Inspect these items when the engine is cold.
1. REPLACE TIMING BELT (See pages EM-12 and
EM-17)
2. INSPECT DRIVE BELTS (See pages CH-2, SR-3 and
AC-18)
3. INSPECT AIR FILTER
(a) Visually check that the air filter is not excessively dirty,
damaged or oily.
If necessary, replace the air filter.
(b) Clean the air filter with compressed air.
First blow from the upper side thoroughly, then blow off
the lower side of the air filter.
4. REPLACE AIR FILTER
Replace the air filter with a new one.
5. REPLACE SPARK PLUGS (See page IG-1)
6. REPLACE ENGINE OIL AND OIL FILTER (See page
LU-3)
7. REPLACE ENGINE COOLANT (See page CO-2)
8. INSPECT CHARCOAL CANISTER (See page EC-5)
9. REPLACE GASKET IN FUEL TANK CAP (See page
EC-5)
10. INSPECT FUEL LINES AND CONNECTIONS (See
page EC-5)
11. INSPECT EXHAUST PIPES AND MOUNTINGS
Visually check the pipes, hangers and connections for severe
corrosion, leaks or damage.
12. ADJUST VALVE CLEARANCE (See page EM-4)
