2008 JEEP COMPASS air filter

Circulation Control
Use this button to choose be-
tween outside air intake or
recirculation of the air inside
the vehicle. A lamp will illu-
minate when you are in recir-
culate mode. Only use the re-
circulate mode to temporarily
block out any outside odors,
smoke, or dust and to cool the
interior rapidly upon initial
start up in very hot or humid
weather.
NOTE:Continuous use of the recirculate mode may
make the inside air stuffy and window fogging may
occur. Extended use of this mode is not recommended.
In cold or damp weather, the use of the Recirculate
position will cause windows to fog on the inside becauseof moisture build up inside the vehicle. For maximum
defogging, select the Outside Air position.
NOTE:Recirculation Mode will not operate in floor, mix
or defrost modes.
Air Filtration System ± If Equipped
An air filter is included in the optional Security Group.
Filter media includes a particle filtration layer and a
charcoal layer. The filter will reduce, but not eliminate,
diesel and agricultural smells. The filter acts only on air
coming from outside the vehicle; it does not filter air
inside the passenger compartment. See the maintenance
schedule for the filter change interval. The air filter
change interval coincides with engine oil and filter
change intervals. As with oil changes, the interval is
shorter for heavy duty service or dusty conditions. See
your authorized dealer for service.

American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
Engine Oil Viscosity (SAE Grade)
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low tempera-
ture starting and vehicle fuel economy. Your engine oil
filler cap also states the recommended engine oil vis-
cosity grade for your engine.Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber 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.
Materials Added To Engine Oils
The manufacture 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
it's performance may be impaired by supplemental ad-
ditives.

Fuel Filter
A plugged fuel filter can cause hard starting or limit the
speed at which a vehicle can be driven. Should an
excessive amount of dirt accumulate in the fuel tank,
frequent filter replacement may be necessary. The fuel
filters are located inside the fuel tank. See your dealer for
service.
Air Cleaner Element (Filter)
Replace the filter at the intervals shown in the ªMainte-
nance Schedule.º Refer to Section 8 of this manual.
WARNING!
The air cleaner can provide a measure of protection
in the case of engine backfire. Do not remove the air
cleaner unless such removal is necessary for repair or
maintenance. Make sure that no one is near the
engine compartment before starting the vehicle with
the air cleaner removed. Failure to do so can result in
serious personal injury.

Automatic Transaxle (CVT)
Selection Of Lubricant
It is important that the proper lubricant is used in the
transaxle to assure optimum transaxle performance. Use
only the manufacturer's recommended transmission
fluid which has been formulated with special metal to
metal friction coefficient additives to provide the proper
steel belt traction on the drive and driven pulleys. Refer
to ªFluids, Lubricants and Genuine Partsº for correct
fluid type.
CAUTION!
Using a transmission fluid other than the manufac-
turers recommended fluid will cause belt slip and
result in a complete transmission failure! Refer to
ªFluids, Lubricants, and Genuine Partsº for correct
fluid type.
Fluid Level Check
The fluid level in the automatic transaxle should be
checked only by a trained technician.
Fluid and Filter Changes
Refer to the ªMaintenance Scheduleº in Section 8 of this
manual for the correct change interval.
Special Additives
Do not add any materials (other than leak detection dyes)
to Continuously Variable Transaxle (CVT) Fluid
(CVTF+4). CVTF+4 is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Manual Transaxle
Lubricant Selection
Use only the manufacturers recommended transmission
fluid. Refer to ªFluids, Lubricants, and Genuine Partsº
for correct fluid type.
