2008 DODGE VIPER battery

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 system isnot readyand you shouldnot
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 system
isreadyand you can proceed to the I/M station.
If your OBD system isnot 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
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 system is
ready or not ready, if the MIL symbol 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 symbol is on
with the engine running.
REPLACEMENT PARTS
Use of genuine Mopartparts for normal/scheduled
maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-Mopartparts for maintenance
and repairs will not be covered by the manufacturer's
warranty.

quality filters should be used to assure most efficient
service. MopartEngine Oil Filters are a high quality oil
filter and are recommended.
Drive Belts Ð 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 at the specified intervals and re-
placed if required. Improper belt tension can cause belt
slippage and failure. Low generator belt tension can
cause battery failure.
At the intervals indicated on the ªMaintenance Sched-
ules,º inspect belt and belt tensioner condition. Inspect
belts for evidence of cuts, cracks, glazing, or frayed cords
and replaced if there is indication of damage, which 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.8.4L ACCESSORY BELT ROUTING

NOTE:
²Because of the plastic body shell on your vehicle,
ignition cables should be replaced with the specially
designed RFI cables available at your dealer.
²The ignition timing cannot be set on this engine.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from plugging due to deposits. As vehicle mileage builds
up, the Crankcase Ventilation Valve orifice may accumu-
late deposits. If a valve is not working properly, it should
be replaced with a new orifice. DO NOT ATTEMPT TO
CLEAN THE OLD ORIFICE!
Check the ventilation hose for indication of damage or
plugging deposits and replace if necessary. See your
authorized dealer for service.
Maintenance-Free Battery
The top of the MAINTENANCE-FREE battery is perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
The battery is located underneath an access panel inside
the rear compartment on the left side of the vehicle. A
remote battery terminal is located in the engine compart-
ment for jump-starting.
