2008 DODGE AVENGER maintenance

NOTE: Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options, or authorized dealer-installed
options, must be considered as part of the total load on
your vehicle. Refer to the Tire and Loading Information
placard in the Tire Safety Information Section of this
manual for the maximum combined weight of occupants
and cargo for your vehicle.
CAUTION!Incorrect trailer tongue weight could result in in-
creased yaw or vehicle instability. A negative trailer
tongue weight could unload the rear suspension of
the tow vehicle decreasing vehicle stability. Negative
trailer tongue weight could cause the trailer to squat
and potentially become disengaged from the tow
vehicle resulting in a runaway trailer condition. Towing Requirements
To promote proper break-in of your new vehicle driv-
etrain components the following guidelines are recom-
mended:
CAUTION!² Avoid towing a trailer for the first 500 mi (805 km)
of vehicle operation. Doing so may damage your
vehicle.
² During the first 500 mi (805 km) of trailer towing,
limit your speed to 50 mph (80 km/h).
Perform the maintenance listed in Section 8 of this
manual. When towing a trailer, never exceed the GAWR,
or GCWR, ratings. STARTING AND OPERATING 339

Automatic Transaxle
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, third
gear for a four-speed automatic and the fifth gear for a
six-speed AutoStick t should be selected.
NOTE: Using third or fifth instead of DRIVE while
operating the vehicle under heavy operating conditions,
will improve performance and extend transaxle life by
reducing excessive shifting and heat build-up. This ac-
tion will also provide better engine braking.
If you REGULARLY TOW a trailer for more than 45
minutes of continuous operation, then change the auto-
matic transaxle fluid and filter according to the interval
specified for ªpolice, taxi, fleet, or frequent trailer tow-
ingº in the ªMaintenance Scheduleº in this manual.
NOTE: Check the four-speed automatic transaxle fluid
level before towing. AutoStick t sixÐspeed transmission is sealed and the fluid level cannot be checked. See your
authorized dealership service center for assistance.
Electronic Speed Control Ð (If Equipped)
² Don't use in hilly terrain or with heavy loads.
² 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.
² Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transaxle overheating,
take the following actions:
² City Driving
When stopped for short periods of time, put transaxle in
neutral and increase engine idle speed.344 STARTING AND OPERATING

² Highway Driving
Reduce speed.
² Air Conditioning
Turn off temporarily.
² Refer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.
If you have any questions or concerns after reviewing
this section, please consult your authorized dealer to for
full details on the towing capabilities of the vehicle. RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Towing This Vehicle Behind Another Vehicle (Flat
towing with all four wheels on the ground)
CAUTION!DO NOT flat tow this vehicle. Damage to the driv-
etrain will result.
NOTE: If the vehicle requires towing make sure all four
wheels are off the ground. STARTING AND OPERATING 345

WARNING!A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
ENGINE OIL OVERHEATING (2.4L ENGINE ONLY)
Ð IF EQUIPPED
During sustained high-speed driving or trailer tow up
long grades on a hot day, the engine oil temperature may
become too hot. If this happens, the ªHOTOILº message
flashes in the odometer and the vehicle speed will be
reduced to 53 mph (85 km/h) until the engine oil
temperature is reduced. NOTE: The vehicle speed is reduced to a maximum of
53 mph (85 km/h). You may of course, reduce your
vehicle speed further if needed.
JACKING AND TIRE CHANGING
WARNING!² Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
² The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.350 WHAT TO DO IN EMERGENCIES

5. Connect the other cable, first to the negative terminal
of the booster battery and then to the engine ground (-)
of the vehicle with the discharged battery. Make sure
you have a good contact on the engine ground. Refer to
the following illustration for jump-starting connections.
6. If the vehicle is equipped with Sentry Key t Immobi-
lizer, turn the ignition switch to the ON position for three
seconds before moving the ignition switch to the START
position.
7. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
8. When removing the jumper cables, reverse the se-
quence exactly. Be careful of the moving belts and fan.
9. Reinstall the protective cover over the remote jump-
start positive battery post. NOTE: Refer to ªMaintenance Proceduresº in Section 7
of this manual for information on accessing the battery
for service or replacement.
WARNING!Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting out
the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.360 WHAT TO DO IN EMERGENCIES

RESET button to turn off the message. If the 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
light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of this 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 the 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, the vehicle may fail the test.
This vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if this vehicle's OBD II system is ready, you must
do the following:
1. Insert the 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 the ignition key to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.372 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 the
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 the vehicle's OBD II
system is ready, and you can proceed to the I/M
station.
If the OBD II system is not ready, you should see an
authorized dealer or repair facility. If this vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive the vehicle as you normally would in order for the OBD II system to
update. A recheck with the above test routine may then
indicate that the system is now ready.
Regardless of whether the vehicle's OBD II system is
ready or not ready, if the MIL is illuminated during
normal vehicle operation, you should have the vehicle
serviced before going to the I/M station. The I/M station
can fail the 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. MAINTAINING YOUR VEHICLE 373
