2008 DODGE MAGNUM SRT fuel cap

Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) (if equipped). If this
occurs, tighten the fuel filler cap properly and press the
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 your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.For states that require an I/M (Inspection and
Maintenance), this check verifies the MIL is func-
tioning and is not on when the engine is running,
and that the OBD II system is ready for testing.
Normally, the OBD system will be ready. The OBD II
system maynotbe ready if your vehicle was recently
serviced or recently had a dead battery or had a battery
replacement. If the OBD II 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 II 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.
382 MAINTAINING YOUR VEHICLE

Ensure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of wear or damage that could cause failure.
Fuel System
The Electronic Fuel Injection high-pressure fuel system’s
hoses and quick connect fittings have unique material
characteristics that provide adequate sealing and resist
attack by deteriorated gasoline.
You are urged to use only the manufacturer’s specified
hoses with quick connect fittings, or their equivalent in
material and specification, in any fuel system servicing. It
is mandatory to replace any damaged hoses or quick
connect fittings that have been removed during service.Care should be taken with installing quick connect
fittings to ensure they are properly installed and fully
connected. See your authorized dealer for service.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the “Mainte-
nance Schedule” in Section 8.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
