2013 JEEP WRANGLER Owners Manual

Side Window Demisters
A side window demister outlet is located at each end of
the instrument panel. These non-adjustable outlets direct
air toward the side windows when the system is in the
Floor, Mix, or Defrost mode. The air is directed at the area
of the windows through which you view the outside
mirrors.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
winter months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter — If Equipped
The A/C Filter prevents most dust and pollen from enter-
ing the cabin. The filter acts on air coming from outside the
vehicle and recirculated air within the passenger compart-
ment. Refer to “Maintenance Procedures” in “Maintaining
Your Vehicle” for A/C Air Filter service information or see
your authorized dealer for service. Refer to “Maintenance
Schedules” for filter service intervals.

•When leaving the vehicle, always remove the key
fob from the ignition and lock your vehicle.

number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the shift lever.
