How to Handle BatteryINFOID:0000000001328243
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.
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.
 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, immediately flush wit h water for 15 minutes and seek medical attention.

STARTING SYSTEM
STARTING SYSTEM
System DescriptionINFOID:0000000001328246
Power is supplied at all times
 through 40A fusible link (letter F, located in the fuse and fusible link block)
 to ignition switch terminal 1,
 through 15A fuse (No. 78, located in the IPDM E/R)
 to CPU of IPDM E/R,
 through 10A fuse (No. 71, located in the IPDM E/R)
 to CPU of IPDM E/R.
When the selector lever in the P or N position, power is supplied
 from TCM, and through A/T assembly terminal 9
 to IPDM E/R terminal 53.
Ground is supplied
 to IPDM E/R terminals 38, 50 and 60
 from grounds E21, E50 and E51.
With the ignition switch in the START position, and provided that the IPDM E/R receives a starter relay ON sig-
nal from the CAN lines, the IPDM E/ R is energized and power is supplied
 from ignition switch terminal 5
 to IPDM E/R terminal 4 and
 through IPDM E/R terminal 3
 to starter motor terminal 1.
The starter motor plunger closes and provides a clos ed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.
