air filter JEEP WRANGLER 2017 JK / 3.G Owners Manual

Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy
and/or humid weather. To clear the windows, select De-
frost or Mix mode and increase the front blower speed. Do
not use the Recirculation mode without A/C for long
periods, as fogging may occur.
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.
Cabin Air Filter
The climate control system filters out dust and pollen from
the air. Contact your authorized dealer to service your
cabin air filter, and to have it replaced when needed.

The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the “Engine Compart-
ment” illustration in this section.
NOTE:MOPAR SAE 5W-30 engine oil approved to FCA
Material Standard MS-6395 such as Pennzoil, Shell Helix or
equivalent may be used when SAE 5W-20 engine oil
meeting MS-6395 is not available.
Lubricants which do not have both the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes are
followed.
Synthetic engine oils which do not have both the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service sta-
tion or governmental agency for advice on how and where
used oil and oil filters can be safely discarded in your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter at
every engine oil change.
Engine Oil Filter Selection
This manufacturer’s engines have a full-flow type dispos-
able oil filter. Use a filter of this type for replacement. The
quality of replacement filters varies considerably. Only
high quality filters should be used to assure most efficient
service. MOPAR engine oil filters are high quality oil filters
and are recommended.
