2004 JEEP GRAND CHEROKEE battery

To determine the battery charge, check the battery test
indicator (if equipped) on top of the battery. Refer to the
illustration.
CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
negative post. Battery posts are marked (+) positive
and negative (-) and identified on the battery case.
Also, if a ªfast chargerº is used while battery is in the
vehicle, disconnect both vehicle battery cables be-
fore connecting the charger to battery. Do not use a
ªfast chargerº to provide starting voltage.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an Authorized Dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.

Your vehicle is equipped with an electrical power distri-
bution center located in the engine compartment near the
battery. This power center houses plug-in ªCartridgeº
fuses which replace in-line fusible links. The power
center also contains ªMiniº fuses and plug-in full and
mini ISO relays. A label inside the latching cover of the
288 MAINTAINING YOUR VEHICLE

center identifies each component for ease of replacement,
if necessary. ªCartridgeº fuses and relays can be obtained
from your authorized dealer.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
²Remove Cartridge fuse #15 in the Power Distribution
Center labeled Ignition-Off Draw (IOD).
²Store the removed IOD fuse in the Power Distribution
Center location #11 labeled ªIOD Storage.º
²Or, disconnect the negative cable from the battery.
²Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This willinsure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
