2015 JEEP COMPASS air filter

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
entering the cabin. The filter acts on air coming from
outside the vehicle and recirculated air within the pas-
senger compartment. 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” in “Maintaining Your
Vehicle” for filter service intervals.
308 UNDERSTANDING YOUR INSTRUMENT PANEL

To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•Drain the fuel tank (see your authorized dealer).
•Change the engine oil and oil filter.
•Disconnect and reconnect the battery to reset the
engine controller memory.
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.

excessive shifting and heat buildup. This action will also
provide better engine braking.
If you REGULARLY tow a trailer for more than 45 min-
utes of continuous operation, then change the transmis-
sion fluid and filter as specified for#police, taxi, fleet, or
frequent trailer towing#. Refer to the#Maintenance
Schedule#for the proper maintenance intervals.
AutoStick® — If Equipped
When using the AutoStick® shift control, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose#4#if
the desired speed can be maintained. Choose#3#or#2#if
needed to maintain the desired speed.
To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as necessary
to avoid extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and road
conditions allow.
Electronic Speed Control — If Equipped
•Do not use in hilly terrain or with heavy loads.
•When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
•Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.
Engine Oil Viscosity (SAE Grade)
MOPAR® SAE 5W-20 engine oil or equivalent Pennzoil®
or Shell Helix® is recommended for all operating tem-
peratures. This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also states the recommended engine oil viscosity
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 Oil
The manufacturer strongly recommends against the ad-
dition 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 addi-
tives.
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

station 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 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 a high quality oil
filter and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) 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 induction system (air cleaner,
hoses, etc.) removed. Failure to do so can result in
serious personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. MOPAR® engine air
cleaner filters are a high quality filter and are recom-
mended.
