2007 DODGE MAGNUM check engine light

A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
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, which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD 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 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 your 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
your vehicle’s OBD system isnot readyand you
shouldnotproceed to the I/M station.

WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Master Cylinder - Brake Fluid Level Check
Check the fluid level in the master cylinder immediately
if the brake system warning light indicates system fail-
ure.
Check the fluid level in the master cylinder when per-
forming underhood services.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
“FULL” mark on the side of the master cylinder reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the require-
ments described on the brake fluid reservoir. With discbrakes, fluid level can be expected to fall as the brake
pads wear. However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only manufacturer’s recommended brake fluid. Re-
fer to “Fluids, Lubricants, and Genuine Parts” for the
correct fluid type.WARNING!
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
•Use of a brake fluid that has a lower initial boiling
point than the recommended MOPARDOT 3
product or a brake fluid that is unidentified as to
FMVSS specification may result in sudden brake
failure during hard prolonged braking. You could
have an accident.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.

the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•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 termi-
nals as required.
•Check the fluid levels of coolant reservoir and brake
master cylinder, and add as needed.
•Check all lights and all other electrical items for correct
operation.
•Check rubber seals on each side of the radiator for
proper fit.
At Each Oil Change
•
Change the engine oil filter.
•Inspect the exhaust system.
•Inspect the brake hoses.
•Inspect the CV joints and front and rear suspension
components.
•Check the coolant level, hoses, and clamps.
