Chrysler Aspen (2009 year). Instruction — part 24
The least amount of accelerator pedal pressure to main-
tain the rocking motion without spinning the wheels or
racing the engine is most effective. Allow the engine to
idle with the shift lever in NEUTRAL for at least one
minute after every five rocking-motion cycles. This will
minimize overheating and reduce the risk of transmis-
sion failure during prolonged efforts to free a stuck
vehicle.
EMERGENCY TOW HOOKS — IF EQUIPPED
Your vehicle may be equipped with emergency tow
hooks.
NOTE:
For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of
damage to the vehicle.
WARNING!
• Chains are not recommended for freeing a stuck
vehicle. Chains may break, causing serious injury
or death.
• Stand clear of vehicles when pulling with tow
hooks. Tow straps and chains may break, causing
serious injury.
CAUTION!
Tow hooks are for emergency use only, to rescue a
vehicle stranded off-road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle.

TOWING A DISABLED VEHICLE
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use of safety chains is recom-
mended. Attach towing device to main structural mem-
bers of the vehicle — not to bumpers or associated
brackets. State and local laws, applying to vehicles
under tow, must be observed.
Four-Wheel Drive Vehicles
The manufacturer recommends towing with all wheels
OFF
the ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of the vehicle raised
and the opposite end on a towing dolly.
Two-Wheel Drive Vehicles
Provided that the transmission is operable, tow with the
transmission in NEUTRAL and the ignition key in the
OFF position, along with the front wheels raised and the
rear wheels on the ground. The speed must not exceed 30
mph (50 km/h), and the distance must not exceed 15
miles (25 km).
If the vehicle is to be towed more than 15 miles (25 km)
or faster than 30 mph (50 km/h), it must be towed on a
flatbed, or with the rear wheels raised and the front
wheels on the ground, or with the front end raised and
the rear wheels on a towing dolly.
NOTE:
Towing the vehicle with the rear wheels on the
ground at more than 30 mph (50 km/h) or for more than
15 miles (25 km), can cause severe transmission damage.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
• Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability.
The vehicle must be serviced before any emissions
tests can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose, improp-
erly installed, or damaged. A loose fuel filler cap message
will be displayed in the instrument cluster. Tighten the
gas cap until a
9clicking9 sound is heard. This is an
indication that the gas cap is properly tightened. Press
the odometer RESET button to turn the message off. If the
MAINTAINING YOUR VEHICLE
387

-------------------------------------------------------------------------------------------------------------------------------------------------------------
problem persists, the message will appear the next time
the vehicle is started. This might indicate a damaged cap.
If the problem is detected twice in a row, the system will
turn on the MIL. Resolving the problem will turn the MIL
off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and Mainte-
nance (I/M), this check verifies the Malfunction
Indicator Light (MIL) is functioning and is not on
when the engine is running, and that the OBD II system
is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a dead battery, or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see the MIL symbol come on as part of a normal bulb
check.
388
MAINTAINING YOUR VEHICLE
-------------------------------------------------------------------------------------------------------------------------------------------------------------
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition key or start the engine. This means that
your vehicle’s OBD II system is not ready and you
should not proceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition key or start
the engine. This means that your vehicle’s OBD II
system is ready , and you can proceed to the I/M
station.
If your OBD II system is not ready, you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD II
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD II system is
ready or not ready, if the MIL is illuminated during
normal vehicle operation, you should have your vehicle
serviced before going to the I/M station. The I/M station
can fail your vehicle because the MIL is on with the
engine running.
REPLACEMENT PARTS
Use of genuine MOPAR
t parts for normal/scheduled
maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-MOPAR
t parts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.

DEALER SERVICE
Your authorized dealer has the qualified service person-
nel, special tools and equipment to perform all service
operations in an expert manner. Service Instructions are
available which include detailed service information for
your vehicle. Refer to these instructions before attempting
any procedure yourself.
NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which
you have the knowledge and the proper equipment.
If you have any doubt about your ability to perform
a service job, take your vehicle to a competent
mechanic.
MAINTENANCE PROCEDURES
The pages that follow contain the required maintenance
services determined by the engineers who designed your
vehicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. The
best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off or
before starting the engine after it has sat overnight.
390
MAINTAINING YOUR VEHICLE
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding 1 quart/liter of oil when the reading is
at the bottom of the SAFE zone will result in a reading at
the top of the SAFE zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
Change Engine Oil
Refer to the Maintenance Schedule in Section 8 for
recommended engine oil change intervals.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends engine oils that are API certified and meet
the requirements of Chrysler Material Standard MS-6395.
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 temperature
starting and vehicle fuel economy.
MAINTAINING YOUR VEHICLE
391

-------------------------------------------------------------------------------------------------------------------------------------------------------------
The engine oil filler cap also shows the recommended
engine oil viscosity for your vehicle. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in this section.
NOTE:
Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in improper
operation of the Multiple Displacement System (MDS).
Refer to “Multi Displacement System” under “Starting
and Operating” in Section 5.
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 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
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
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 at every engine
oil change.
392
MAINTAINING YOUR VEHICLE
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Engine Oil Filter Selection
The 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
t engine oil filters are a high quality oil
filter and are recommended.
Engine Air Cleaner Filter
Refer to the Maintenance Schedule in Section 8 for
recommended engine air cleaner filter change intervals.
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
The top of the maintenance-free battery is permanently
sealed. You will never have to add water, nor is periodic
maintenance required.

the negative post. Battery posts are marked (+)
positive and negative (-) and identified on the
battery case.
• If a “fast charger” is used while battery is in
vehicle, disconnect both vehicle battery cables
before connecting the charger to battery. Do not
use a “fast charger” to provide starting voltage.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
394
MAINTAINING YOUR VEHICLE
-------------------------------------------------------------------------------------------------------------------------------------------------------------
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.
WARNING!
• Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer to
Section 3 of the Warranty Information book for
further warranty information.
• The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced technician.
NOTE:
Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oils and Refrigerants.
Refrigerant Recovery and Recycling
R-134a air conditioning refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by authorized dealers or other
service facilities using recovery and recycling equipment.
Drive Shaft Constant Velocity Joints
All 4-wheel drive models are equipped with four con-
stant velocity joints. Periodic lubrication of these joints is
not required. However, the joint boot should be inspected
for external leakage or damage periodically. If external
leakage or damage is evident, the joint boot and grease
should be replaced immediately. Continued operation
could result in failure of the joint due to water and dirt
