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.
