2007 JEEP COMPASS air filter

In cold or damp weather, the use of the Recirculate
position will cause windows to fog on the inside because
of 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. The filter ’s normal
service life is 12,000 miles (20,000 km) or one year. The air
filter change schedule coincides with that for engine oil
and filter. As with oil changes, the interval is shorter for
heavy duty service or dusty conditions. See your autho-
rized dealer for service.

Towing Tips — Automatic Transmission
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See Schedule “B” in
section 8 of this manual for transmission fluid change
intervals.
NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — Electronic Speed Control (If
Equipped)

Don’t 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.
Towing Tips — Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in neutral but do not increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
refer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.

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)
Under normal driving conditions, replace the filter at the
intervals shown on Schedule “A”. If, however, you drive
the vehicle frequently under dusty or severe conditions,
the filter element should be inspected periodically and
replaced if necessary at the intervals shown on Schedule
“B”.
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.
Maintenance-Free Battery
You will never have to add water, nor is periodic main-
tenance required.

Fluid and Filter Changes
Refer to the “Maintenance Schedule located if section 8 of
this manual for the correct change interval for your type
of driving.
Special Additives
Do not add any materials (other than leak detection dyes)
to Automatic Transmission Fluid (ATF). ATF is an engi-
neered product and its performance may be impaired by
supplemental additives.
Manual Transaxle
Lubricant Selection
Use only manufacturers recommended transmission
fluid. Refer to Fluids, Lubricants and Genuine Parts for
correct fluid type.
Fluid Level Check
Check the fluid level by removing the fill plug. The fluid
level should be between the bottom of the fill hole and a
point not more that 3/16” (4.7 mm) below the bottom of
the hole.
Add fluid, if necessary, to maintain the proper level.
Frequency Of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. Fluid changes are not necessary unless the
following conditions exist:
•The lubricant has become contaminated with water. If
contaminated with water, the fluid should be changed
immediately.
•If severe usage has occurred, refer to Maintenance
Schedule “B” in Section 8 of this manual.
