Jeep Wrangler: SERVICING AND MAINTENANCE / STORING THE VEHICLE
WARNING!
- Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can
be injured by moving fan blades.
- Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact. You
could be seriously injured.
- Vehicles with the Stop/Start system will be
equipped with two batteries. Both the main
and the supplemental batteries must be
disconnected to completely de-energize the
12 Volt electrical system.
- Serious injury or death could result if you do
not disconnect both batteries. To learn how
to properly disconnect, see an authorized
dealer.
CAUTION!
If the negative battery cables are not isolated
properly it can cause a potential power spike
or surge in the system, resulting in damage to
essential electrical components.
If you are storing your vehicle for more than
3 weeks, we recommend that you take the
following steps to minimize the drain on your
vehicle's battery:
- Disconnect the negative cable from battery.
- If your vehicle is equipped with Stop/Start
system then disconnect both the main and
supplemental negative battery cables.
- Any time 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 will ensure
adequate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
- If assistance is needed to disconnect the
battery system, see an authorized dealer.

Battery Cable Disconnect
- Supplemental Negative Battery Cable
- Main Negative Battery Cable
- Intelligent Battery Sensor (IBS)
- Main Negative Battery Terminal
NOTE:
- You must isolate the supplemental battery
connection point, as well as the main battery
terminal from the post, as shown in the image,
to fully de-energize both batteries for storage.
If assistance is needed to disconnect the
battery system, see an authorized dealer.
- Do not disconnect the Intelligent Battery
Sensor (IBS), or your Stop/Start system may
not function for up to 24 hours, due to the IBS
being set into learn mode.

Other information:
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor
coming from the front of the engine compartment.
This is normally a result of moisture from
rain, snow, or high humidity accumulating on
the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze)
to enter the radiator...
