2008 DODGE CHALLENGER battery

6. Connect the other cable, first to the negative terminal
of the booster battery andthen 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. 7. Start the engine in the vehicle that has the booster
battery. Let the engine idle a few minutes. Then, start the
engine in the vehicle with the discharged battery.
NOTE:
Refer toSynchronizing ESP under Electronic
Stability Program in Section 5 if the ESP/BAS light (in
the instrument cluster) remains on continuously after
starting the engine of the vehicle with the discharged
battery.
8. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.

WARNING!
•You should not try to start your vehicle by pushing
or towing.
•Do not connect the cable to the negative post of the
discharged battery. The resulting electrical spark
could cause the battery to explode.
•During cold weather when temperatures are be-
low the freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump-starting
because the battery could rupture or explode. The
battery temperature must be brought above the
freezing point before attempting jump-start.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between RE-
VERSE and DRIVE. Usually, the least accelerator pedal
pressure to maintain the rocking motion without spin-
ning the wheels is most effective.
NOTE: Turn off the Electronic Stability Program (ESP)
before rocking the vehicle. Refer to “Electronic Stability
Program,” or “Traction Control” in Section 5.

Trip Odometer button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.
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 notbe 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.

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 readyand 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
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 parts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.

Materials Added to Engine Oil
The manufacturer 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 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 sta-
tion, 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.
Engine Oil Filter Selection
This manufacturer’s engines have a full-flow type oil
filter. Use a filter of this type for replacement. The qualityof 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.
Drive Belts — Check Condition And Tension
Belt tension is controlled by means of an automatic
tensioner. Therefore, no belt tension adjustments are
required. However, belt and belt tensioner condition
should be inspected periodically and replaced if re-
quired. Improper belt tension can cause belt slippage and
failure. Low generator belt tension can cause battery
failure.
Inspect belts for evidence of cuts, cracks, glazing, or
frayed cords and replace if there is indication of damage
that could result in belt failure. Also, check belt routing to
make sure there is no interference between the belts and
other engine components. See your authorized dealer for
service.

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.
NOTE:The battery is stored under an access cover in
the trunk. Remote battery terminals are located in the
engine compartment for jump starting (Refer to Jump
Starting in Section 6 of this manual).
