PRECAUTIONS AND PREPARATION

How to Handle Battery
CAUTION:
If it becomes necessary to start the engine with a booster bat-
tery and jumper cables,
1) Use a 12-volt booster battery.
2) After connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharg-
ing a battery.
IThe battery surface (particularly its top) should always be kept
clean and dry.
IThe terminal connections should be clean and tight.
IAt every routine maintenance, check the electrolyte level.
This also applies to batteries designated as ªlow maintenanceº
and ªmaintenance-freeº.
IWhen the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.
ICheck the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep
a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Do not allow battery fluid to come in contact with skin, eyes,
fabrics, or painted surfaces. After touching a battery, do not
touch or rub your eyes until you have thoroughly washed your
hands. If acid contacts eyes, skin or clothing, immediately
flush with water for 15 minutes and seek medical attention.

Checking Steering Wheel Play
1. With wheels in a straight-ahead position, check steering wheel
play.
Steering wheel play:
35 mm (1.38 in) or less
2. If it is not within specification, check steering gear assembly
when front suspension and axle, steering gear assembly and
steering column are mounted correctly.
Checking Neutral Position on Steering Wheel
CHECKING
1. Check that the steering wheel is in the neutral position when
driving straight ahead.
2. If it is not in the neutral position, remove the steering wheel and
reinstall it correctly.
3. If the neutral position is between two serrated teeth, loosen
tie-rod lock nut and move tie-rod in the opposite direction by the
same amount on both left and right sides to compensate for
error in the neutral position.
Front Wheel Turning Angle
Rotate steering wheel all the way right and left; measure turning
angle.
Turning angle of full turns:
Refer to section FA for SDS.
Checking and Adjusting Drive Belts
Refer to section MA for Drive Belt Inspection.
Checking Fluid Level
Check the fluid level in the reservoir when the engine is cold. If the
fluid level is below the MIN line, and fluid up to the MAX line.
CAUTION:
IDo not overfill.
IUse only ªDEXRON
TMº type automatic transmission fluid.

Checking Fluid Leakage
Check the lines for improper attachment and for leaks, cracks,
damage, loose connections, chafing or deterioration.
1. Run engine between idle speed and 1,000 rpm.
Make sure temperature of fluid in oil tank rises to 60 to 80ÉC
(140 to 176ÉF).
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each ªlockº position for five seconds and
carefully check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
4. If fluid leakage at connectors is noticed, loosen flare nut and
then retighten.
Do not overtighten connector as this can damage O-ring,
washer and connector.
Bleeding Hydraulic System
1. Raise front end of vehicle until wheels are clear of the ground.
2. Add fluid into oil tank to specified level. Meanwhile quickly turn
steering wheel fully to right and left and lightly touch steering
stoppers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine.
Repeat step 2 above.
IIncomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a. Generation of air bubbles in reservoir tank
b. Generation of clicking noise in oil pump
c. Excessive buzzing in oil pump
While the vehicle is stationary or while moving the steering wheel
slowly, fluid noise may occur in the valve or oil pump. This noise is
inherent in this steering system, and it will not affect performance
or durability of the system.

Checking Steering Wheel Turning Force
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-
ture.
Temperature:
60É - 80ÉC (140 - 176ÉF)
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360É from neutral position.
Steering wheel turning force:
39 N (4 kg, 9 lb) or less
IIf steering wheel turning force is not within specification,
perform the following inspection procedure:

Checking Hydraulic System
Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve, then bleed air. (Refer to ªBleed-
ing Hydraulic Systemº, ST-5.)
2. Run engine.
Make sure temperature of fluid in tank rises to 60 to 80ÉC (140
to 176ÉF).
WARNING:
Warm up engine with shut-off valve fully opened. If engine is
started with shut-off valve closed, oil pressure in oil pump will
increase to relief pressure, resulting in an abnormal rise in oil
temperature.
3. Check pressure with steering wheel fully turned to left and right
positions with engine idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
Oil pump maximum standard pressure:
TD27Ti engine
8,800 - 9,200 kPa (88 - 92 bar,
89 - 93 kg/cm
2, 1,276 - 1,334 psi)
ZD30DTi engine
9,800 - 10,500 kPa (98.0 - 105.0 bar,
99.96 - 107.10 kg/cm
2, 1,421 - 1,523 psi)
4. If oil pressure is below the maximum pressure, slowly close
shut-off valve and check pressure.
IWhen pressure reaches maximum pressure, gear is damaged.
IWhen pressure remains below maximum pressure, pump is
damaged.
CAUTION:
Do not close shut-off valve for more than 15 seconds.
5. If oil pressure is higher than maximum pressure, check oil
pump flow control valve.
6. After checking hydraulic system, remove Tool and add fluid if
necessary, then completely bleed air out of system.NST033
