2019 Jeep Grand Cherokee Owner’s Manual — STORING THE VEHICLE

If you are storing your vehicle for more than 21 days, we recommend that you take the following steps to minimize the drain on your vehicle’s battery:

Disconnect the negative cable from battery.

Any time you store your vehicle or keep it out of service (i.e., vacation) for two weeks or more, run the air condi- tioning 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 dam- age when the system is started again.
