ENGINE ELECTRICAL 6D – 3
ON-VEHICLE SERVICE
BATTERY CHARGING
Observe the following safety precautions when
charging the battery:
1. Never attempt to charge the battery when the fluid
level is below the lower level line on the side of the
battery. In this case, the battery must be replaced.
2. Pay close attention to the battery during the
charging procedure.
Battery charging should be discontinued or the rate
of charge reduced if the battery feels hot to the
touch.
Battery charging should be discontinued or the rate
of charge reduced if the battery begins to gas or
spew electrolyte from the vent holes.
3. In order to more easily view the hydrometer blue
dot or ring, it may be necessary to jiggle or tilt the
battery.
4. Battery temperature can have a great effect on
battery charging capacity.
5. The sealed battery used on this vehicle may be
either quick-charged or slow-charged in the same
manner as other batteries.
Whichever method you decide to use, be sure that
you completely charge the battery. Never partially
charge the battery.
JUMP STARTING
JUMP STARTING WITH AN AUXILIARY
(BOOSTER) BATTERY
CAUTION: Never push or tow the vehicle in an
attempt to start it. Serious damage to the emission
system as well as other vehicle parts will result.
Treat both the discharged battery and the booster
battery with great care when using jumper cables.
Carefully follow the jump starting procedure, being
careful at all times to avoid sparking.
WARNING: Failure to carefully follow the jump
starting procedure could result in the following:
1. Serious personal injury, particularly to your
eyes.
2. Property damage from a battery explosion,
battery acid, or an electrical fire.
3. Damage to the electronic components of one or
both vehicles.
Never expose the battery to an open flame or electrical
spark. Gas generated by the battery may catch fire or
explode. Remove any rings, watches, or other jewelry
before working around the battery. Protect your eyes by
wearing an approved set of goggles.
Never allow battery fluid to come in contact with your
eyes or skin.
Never allow battery fluid to come in contact with fabrics
or painted surfaces.
Battery fluid is a highly corrosive acid.Should battery fluid come in contact with your eyes,
skin, fabric, or a painted surface, immediately and
thoroughly rinse the affected area with clean tap water.
Never allow metal tools or jumper cables to come in
contact with the positive battery terminal, or any other
metal surface of the vehicle. This will protect against a
short circuit.
Always keep batteries out of the reach of young
children.
JUMP STARTING PROCEDURE
1. Set the vehicle parking brake.
If the vehicle is equipped with an automatic
transmission, place the selector lever in the “PARK”
position.
If the vehicle is equipped with a manual
transmission place the shift lever in the “NEUTRAL”
position.
Turn “OFF” the ignition.
Turn “OFF” all lights and any other accessory
requiring electrical power.
2. Look at the built-in hydrometer.
If the indication area of the built-in hydrometer is
completely clear, do not try to jump start.
3. Attach the end of one jumper cable to the positive
terminal of the booster battery.
Attach the other end of the same cable to the
positive terminal of the discharged battery.
Do not allow the vehicles to touch each other.
This will cause a ground connection, effectively
neutralizing the charging procedure.
Be sure that the booster battery has a 12 volt rating.
4. Attach one end of the remaining cable to the
negative terminal of the booster battery.
Attach the other end of the same cable to a solid
engine ground (such as the A/C compressor
bracket or the generator mounting bracket) of the
vehicle with the discharged battery.
This ground connection must be at least 450 mm
(18 in) from the battery of the vehicle whose battery
is being charged.
WARNING: Never attach the end of the jumper
cable directly to the negative terminal of the dead
battery.
5. Start the engine of the vehicle with the good battery.
Make sure that all unnecessary electrical
accessories have been turned “OFF”.
6. Start the engine of the vehicle with the dead battery.
7. To remove the jumper cables, follow the above
directions in the reverse order.
Be sure to first disconnect the negative cable from
the vehicle with the discharged battery.
