How to Handle BatteryINFOID:0000000005146573
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 battery cable from the negative terminal. (If
the vehicle has an extended storage switch, turn it off.)
• 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:
Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never touch or rub your eyes until you 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.

Harness LayoutINFOID:0000000005146582
HOW TO READ HARNESS LAYOUT
The following Harness Layouts use a map style grid to help locate
connectors on the drawings:
• Main Harness, Console Sub-harness, Console Switch Sub-har-
ness and Optical Sensor Sub-harness
• Engine Room Harness and Engine Room Sub-harness
• Engine Room Harness (Passenger Compartment)
• Engine Control Harness and Engine Control Sub-harness
• Chassis Harness and Rear Sonar Sensor Sub-harness
• Body Harness, Front Seat LH Harness and Third Row Power Fold-
ing Seat Sub-harness
• Body No. 2 Harness and Front Seat RH Harness
• Rear Seat Harness
• Room Lamp Harness, Room Lamp Sub- harness A, and Room Lamp Sub-harness B
• Back Door Harness, Back Door No. 2 LH Harness, Back Door LH Harness, Back Door No. 2 RH Harness
and Back Door RH Harness
To use the grid reference
1. Find the desired connector number on the connector list.
2. Find the grid reference.
3. On the drawing, find the crossing of the grid reference letter column and number row.
4. Find the connector number in the crossing zone.
5. Follow the line (if used) to the connector.
