0B-20 MAINTENANCE AND LUBRICATION
FINAL INSPECTION
Seats
Check that seat slides smoothly and locks securely at
any position. Also check that reclining mechanism of
front seat back allows it to be locked at any angle.
Seat Belt
Inspect belt system including webbing, buckles, latch
plates, retractors and anchors for damage or wear.
If “REPLACE BELT” label on belt is visible, replace
belt.
Check that seat belt is securely locked.
Battery Electrolyte Level Check
Check that the electrolyte level of all battery cells is
between the upper and lower level lines on the case.
If battery is equipped with built-in indicator, check bat-
tery condition by the indicator.
Accelerator Pedal Operation
Check that pedal operates smoothly without getting
caught or interfered by and other part.
Engine Start
Check engine start for readiness.
On automatic transmission vehicles, try to start the
engine in each gear. The starter should crank only in
“P” (Park) or “N” (Neutral).
On manual transmission vehicles, place the shift le-
ver in “Neutral,” depress clutch pedal fully and try to
start.
Exhaust System Check
Check for leakage, cracks or loose supports.
Clutch (For manual transmission)
Check for the following.
Clutch is completely released when depressing
clutch pedal.
No slipping clutch occurs when releasing pedal and
accelerating.
Clutch itself is free from any abnormal condition.
Gearshift or Select Lever (Transmission)
Check gear shift or select lever for smooth shifting to
all positions and for good performance of transmis-
sion in any position.
With automatic transmission equipped vehicle, also
check that shift indicator indicates properly according
to which position select lever is shifted to.
CAUTION:
With automatic transmission equipped ve-
hicle, make sure that vehicle is at complete
stop when shifting select lever to “P” range
position and release all brakes.
Brake
[Foot brake]
Check the following;
that brake pedal has proper travel,
that brake works properly,
that it is free from noise,
that vehicle does not pull to one side when brake is
applied,
and that brake does not drag.
WARNING:
When carrying out road tests, select a safe
place where no man or no running vehicle is
seen so as to prevent any accident.
WARNING:
Before performing the following check, be
sure to have enough room around the vehicle.
Then, firmly apply both the parking brake and
the regular brakes. Do not use the accelerator
pedal. If the engine starts, be ready to turn off
the ignition promptly. Take these precautions
because the car could move without warning
and possibly cause personal injury or proper-
ty damage.
MAINTENANCE AND LUBRICATION 0B-21
[Parking brake]
Check that lever has proper travel.
Check to ensure that parking brake is fully effective
when the vehicle is stopped on the safe slope and
brake lever is pulled all the way.
Steering
Check to ensure that steering wheel is free from in-
stability, or abnormally heavy feeling.
Check that the vehicle does not wander or pull to
one side.
Engine
Check that engine responds readily at all speeds.
Check that engine is free from abnormal noise and
abnormal vibration.
Body, Wheels and Power Transmitting System
Check that body, wheels and power transmitting sys-
tem are free from abnormal noise and abnormal
vibration or any other abnormal condition.
Meters and Gauge
Check that speedometer, odometer, fuel meter, tem-
perature gauge, etc. are operating accurately.
Lights
Check that all lights operate properly.
Windshield Defroster
Periodically check that air comes out from defroster
outlet when operating heater or air conditioning.
Set fan switch lever to “HI” position and mode lever to
defroster position for this check. WARNING:
With vehicle parked on a fairly steep slope,
make sure nothing is in the way downhill to
avoid any personal injury or property damage.
Be prepared to apply regular brake quickly
even if vehicle should start to move.

FUEL PRESSURE RELIEF PROCEDURE
CAUTION:
This work must not be done when engine is hot. If done so,
it may cause adverse effect to catalyst.
After making sure that engine is cold, release fuel pressure as fol-
lows.
1) Place transmission gear shift lever in “Neutral” (Shift selector le-
ver to “P” range for A / T model), set parking brake, and block
drive wheels.
2) Remove relay box cover.
3) Disconnect fuel pump relay (1) from relay box (2).
4) Remove fuel filler cap to release fuel vapor pressure in fuel tank
and then reinstall it.
5) Start engine and run it till it stops for lack of fuel. Repeat cranking
engine 2-3 times for about 3 seconds each time to dissipate fuel
pressure in lines. Fuel connections are now safe for servicing.
6) Upon completion of servicing, connect fuel pump relay to relay
box and install relay box cover.
FUEL LEAKAGE CHECK PROCEDURE
After performing any service on fuel system, check to make sure
that there are no fuel leakages as follows.
1) Turn ON ignition switch for 2 seconds (to operate fuel pump) and
then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply fuel pressure
to fuel line. (till fuel pressure is felt by hand placed on fuel feed
hose.)
2) In this state, check to see that there are no fuel leakages from
any part of fuel system.
