5. When the repair work is completed, return the ignition switch to the
″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.

How to Handle Battery INFOID:0000000004306818
CAUTION:
• If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.
• After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
• Never add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE The following precautions must be taken to prevent over-discharging
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 specific gr avity 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 touch-
ing a battery, do not touch or rub your eyes until yo u have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, imme diately flush with water for 15 minutes and seek medical attention. MEL041F

CHARGING THE BATTERY
CAUTION:
• Do not “quick charge” a fully discharged battery.
• Keep the battery away from open flame while it is being charged.
• When connecting the charger, connect the leads first, then turn on the charger. Do not turn on the
charger first, as this may cause a spark.
• If battery electrolyte temperature rises above 55 °C (131 °F), stop charging. Alw ays charge battery at a
temperature below 55 °C (131 °F).
Charging Rates
Do not charge at more than 50 ampere rate.
NOTE:
The ammeter reading on your battery charger will automat ically decrease as the battery charges. This indi-
cates that the voltage of the battery is increasing norma lly as the state of charge improves. The charging amps
indicated above refer to initial charge rate.
• If, after charging, the specific gravity of any two ce lls varies more than 0.050, the battery should be replaced.
Trouble Diagnosis with Battery Service Center INFOID:0000000004306819
For battery testing, use Battery Serv ice Center (J-48087). For details and operating instructions, refer to Tech-
nical Service Bulletin and/or Battery Service Center User Guide.
Removal and Installation INFOID:0000000004306820
REMOVAL 1. Disconnect battery negative (1) and positive (2) terminals. CAUTION:
When disconnecting, disconnect the battery negative termi-
nal first.
2. Remove battery hold-down wedge bolt (A) and remove battery hold-down wedge bracket (3).
3. Remove battery cover.
4. Remove battery. −
