Dodge 2009 Charger Owner's Manual page 435

NOTE:
The oil change indicator message will not monitor the
time since the last oil change. Change your vehicle's
oil if it has been six months since your last oil change,
even if the oil change indicator message is NOT
illuminated.
Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or six months, which-
ever comes first.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under "Oil Change
Required" under "Electronic Vehicle Information Center
MAINTENANCE SCHEDULES 433
(EVIC)" in Section 4 or under "Odometer/Trip Odom-
eter" under "Instrument Cluster Descriptions" in Sec-
tion 4.
At Each Stop for Fuel
Check the engine oil level. Refer to "Engine Oil" under
"Maintenance Procedures" in Section 7.
Check the windshield washer solvent and add if
required.
Once a Month
Check tire pressure and look for unusual wear or
damage.
Inspect the battery, and clean and tighten the terminals
as required.
Check the fluid levels of coolant reservoir, brake
master cylinder, power steering, and transmission,
and add as needed.
