NOTE
Some vehicles may have an ultra ca-
pacitor mounted in the battery box.
These devices have a similar shape to
a battery but have two positive posts
and one negative posts. Do not attach
battery chargers to these devices to
recharge the vehicles batteries. Con-
nect directly to the conventional two
post charging batteries to charge
them.
NOTE
Follow the instructions that come with
your battery charger.
1. Access the battery terminals, the
batteries do not have to be
removed from the vehicle.
2. Make sure the battery charger is
turned off.
3. Disconnect the battery cables.
4. Connect charger cables.
5. Start charging the battery at a rate
not over 6 amperes. Normally, a
battery should be charged at no
more than 10 percent of its rated
capacity.
6. After charging, turn OFF charger
and disconnect charger cables.
Alternator
Take the following precautions to avoid
burning out alternator diodes:
• Do not start the engine with
alternator disconnected
(connections removed) from the
circuit.
• Before welding, disconnect all
electronic connections to the
vehicle batteries.
• Remove battery power cable and
insulate it from the vehicle.
• Do not run the engine with the
batteries disconnected.
• Do not disconnect the battery
cables or alternator connection
cables with the engine running.
• Never turn the ignition switch from
the ON position to the START
position with the engine running.
• When charging the battery
(installed in the vehicle) disconnect
the battery cables.
• Do not reverse the cables of the
alternator, starter motor, or battery.
• Do not polarize the alternator. The
alternator should not be polarized
like a generator. To ensure correct
polarity, use a test lamp or a
voltmeter.
Remote Keyless Entry
The remote keyless entry system may
become inoperational due to a key fob
battery.
If you have issues with a key fob, replace
the battery and re-synchronize the key fob.
In some situations, the key fob may need
to be replaced and in others, a fuse may
have failed and may render both key fobs
inoperative. Contact your dealer for more
help if a key fob does not work and it is not
because of a bad battery.

Batteries should last approximately three
years, depending on use. Consistently
reduced range is an indicator that the
battery needs replacement.
