air filter JEEP WRANGLER 2020 Owner handbook (in English)

CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
• Use care when washing the inside of
the rear window. Do not use abrasive
window cleaners on the interior surface
of the window. Use a soft cloth and a
mild washing solution, wiping parallel
to the heating elements. Labels can be
peeled off after soaking with warm
water.
• Do not use scrapers, sharp instru-
ments, or abrasive window cleaners on
the interior surface of the window.
• Keep all objects a safe distance from
the window.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstruc-
tions, 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.
Cabin Air Filter
The climate control system filters out dust
and pollen from the air. Contact an autho-
rized dealer to service your cabin air filter,
and to have it replaced when needed.
POWER WINDOWS — IF
EQUIPPED
The power window switches are located on
the instrument panel below the radio. Push
the switch downward to open the window and
upward to close the window.
The top left switch controls the left front
window and the top right switch controls the
right front window.
WARNING!
Never leave children unattended in a ve-
hicle, and do not let children play with
power windows. Do not leave the key fob in
or near the vehicle, or in a location acces-
sible to children. Occupants, particularly
WARNING!
unattended children, can become en-
trapped by the windows while operating
the power window switches. Such entrap-
ment may result in serious injury or death.
