CAUTION:
If it becomes necessary to start the engine with a booster bat-
tery and jumper cables,
a. Use a 12-volt booster battery.
b. After connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
c. Never add distilled water through the hole used to check
speci®c gravity.
How to Handle Battery
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharg-
ing a battery.
+The battery surface (particularly its top) should always be kept
clean and dry.
+The terminal connections should be clean and tight.
+At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as ``low maintenance''
and ``maintenance-free''.
+When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.
+Check the charge condition of the battery.
Periodically check the speci®c gravity of the electrolyte. Keep
a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Do not allow battery ¯uid 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
¯ush with water for 15 minutes and seek medical attention.

Trouble Diagnoses
Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspec-
tion Table.
+Before starting, inspect the fusible link.
+Use fully charged battery.

Note:
+If the inspection result is OK even though the charging system is malfunctioning, check the B ter-
minal connection. (Check the tightening torque.)
+When ®eld circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary,
replace faulty parts with new ones.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate ``CHARGE'' warning lamp, if any of the following
symptoms occur while alternator is operating:
+Excessive voltage is produced.
+No voltage is produced.

Replacement
For removal and installation of spiral cable, refer to RS section
[``Installation Ð Air Bag Module and Spiral Cable'', ``SUPPLE-
MENTAL RESTRAINT SYSTEM (SRS)''].
+Each switch can be replaced without removing combination
switch base.
+To remove combination switch base, remove base attaching
screw.
+Before installing the steering wheel, align the steering wheel
guide pins with the screws which secure the combination switch
as shown in the left ®gure.

LOW BEAM
1. Turn headlamp low beam on.
2. Use adjusting screws to perform aiming adjustment.
+First tighten the adjusting screw all the way and then make
adjustment by loosening the screw.
+Adjust headlamps so that main axis of light is parallel to
center line of body and is aligned with point P shown in
illustration.
+Figure to the left shows headlamp aiming pattern for driv-
ing on right side of road; for driving on left side of road,
aiming pattern is reversed.
+Dotted lines in illustration show center of headlamp.
