Item Reference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise
specified.
TiresCheck the pressure with a gauge periodically when at a service station, including the
spare, and adjust to the specified pressure if necessary. Check carefully for damage, cuts or
excessive wear.Ð
Windshield wiper bladesCheck for cracks or wear if they do not wipe properly. Ð
Doors and engine hoodCheck that all doors, the engine hood, the trunk lid and back door
operate properly. Also ensure that all latches lock securely. Lubricate hinges, latches, rollers and
links if necessary. Make sure that the secondary latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lubrication fre-
quently.MA-39
Tire rotationTires should be rotated every 10,000 km (6,000 miles) for 2WD models and every
5,000 km (3,000 miles) for 4WD models.MA-35
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the vehicle, etc.
LightsMake sure that the headlights, stop lights, tail lights, turn signal lights, and other lights
are all operating properly and installed securely. Also check headlight aim.Ð
Warning lights and chimesMake sure that all warning lights and chimes are operating prop-
erly.Ð
Steering wheelCheck for change in the steering conditions, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)Ð
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the belt webbing for
cuts, fraying, wear or damage.MA-40
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the
engine oil or refuel.
Windshield washer fluidCheck that there is adequate fluid in the tank. Ð
Engine coolant levelCheck the coolant level when the engine is cold. MA-16, 25
Engine oil levelCheck the level after parking the vehicle on a level spot and turning off the
engine.MA-19, 24
Brake and clutch fluid levelMake sure that the brake and clutch fluid levels are between the
``MAX'' and ``MIN'' lines on the reservoir.MA-32, 35
BatteryCheck the fluid level in each cell. It should be between the ``MAX'' and ``MIN'' lines. Ð
GENERAL MAINTENANCE

Changing Engine Coolant
WARNING:
To avoid being scalded, never change the coolant when the
engine is hot.
Ð DRAINING ENGINE COOLANT Ð
1. Move heater ``TEMP'' control lever all the way to ``HOT''
position.
lMake sure that air condition switch is ``OFF''.
2. Open radiator drain plug at the bottom of radiator, and
remove radiator cap.
3. Remove reservoir tank, drain coolant, then clean reservoir
tank. Install it temporarily.
Be careful not to allow coolant to contact drive belts.

Ð FLUSHING COOLING SYSTEM Ð
5. Install and then tighten radiator drain plug and cylinder block
drain plug securely.
6. Open air relief plug.
7. Fill radiator with water and close air relief plug and radiator
cap.
8. Run engine and warm it up sufficiently.

CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system with cap tester to check for
leakage.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher pressure than the specified value may cause damage
to the radiator.
Checking Fuel Lines
Inspect fuel lines and tank for improper attachment and for leaks,
cracks, damage, loose connections, chafing and deterioration.
If necessary, repair or replace malfunctioning parts.
CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end
is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
Changing Fuel Filter
WARNING:
Before removing fuel filter, release fuel pressure from fuel
line.
1. Remove fuse for fuel pump.
2. Start engine.
3. After engine stalls, crank engine two or three times to make
sure that fuel pressure is released.
4. Turn ignition switch OFF and install fuse for fuel pump.
5. Loosen fuel hose clamps.
6. Replace fuel filter.
lBe careful not to spill fuel or engine compartment. Place
a shop towel to absorb fuel.
lUse a high-pressure type fuel filter. Do not use a syn-
thetic resinous fuel filter.
lWhen tightening fuel hose clamps, refer to ``Checking
Fuel Lines'', MA-18.

between renewals.
Changing Engine Oil
WARNING:
lBe careful not to burn yourself, as the engine oil is hot.
lProlonged and repeated contact with used engine oil
may cause skin cancer; try to avoid direct skin contact
with used oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Remove drain plug and oil filler cap.

lThe refill capacity changes depending on the oil tem-
perature and drain time, use these values as a reference
and be certain to check with the dipstick when changing
the oil.
