2008 DODGE MAGNUM check engine light

CAUTION!
An unlocked car is an invitation to thieves. Always
remove key from the ignition and lock all doors
when leaving the vehicle unattended.
Key-In-Ignition Reminder
If you open the driver's door and the key is in the
ignition, a chime will sound to remind you to remove the
key.
NOTE:The Key-In-Ignition reminder only sounds
when the ignition key is placed in the LOCK or ACC
position.
SENTRY KEY
The Sentry Key Immobilizer System prevents unautho-
rized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses the factory-mated Fob with Integrated
Key and Wireless Ignition Node (WIN) to prevent unau-
thorized vehicle operation. Therefore, only Fobs that are
programmed to the vehicle can be used to start and
operate the vehicle. The system will shut the engine off in
two (2) seconds if someone uses an invalid Fob to start
the engine.
After turning the ignition switch to the ON position, the
Vehicle Security Alarm Indicator Light will turn on for
three (3) seconds for a bulb check. If the light remains on
after the bulb check, it indicates that there is a problem
with the electronics. In addition, if the light begins to

flash after the bulb check, it indicates that someone used
an invalid Fob to start the engine. Either of these condi-
tions will result in the engine being shut off after two (2)
seconds.
If the Vehicle Security Alarm Indicator Light turns on
during normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there is a fault in
the electronics. Should this occur, have the vehicle ser-
viced as soon as possible.
NOTE:
²The Sentry Key Immobilizer System is not compatible
with aftermarket remote starting systems. Use of these
systems may result in vehicle starting problems and
loss of security protection.
²Exxon/Mobil Speed Pass,Ÿ additional Fobs, or any
other transponder-equipped components on the same
key chain willnotcause a fault unless the additional
part isphysically held against the Fobbeing used tostart the vehicle. Cell phones, pagers, or other RF
electronics will not cause interference with this system.
All of the Fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:Only Fobs that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Fob is programmed to a vehicle, it cannot be
programmed to any other vehicle.
CAUTION!
Always remove Sentry Keys from the vehicle and
lock all doors when leaving the vehicle unattended.
At the time of purchase, the original owner is provided
with a four-digit PIN number. Keep the PIN in a secure

6. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should turn on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the light stays on or turns on while
driving, turn off some of the vehicle's non-essential
electrical devices (i.e. radio), or slightly increase engine
speed (if at idle). If the light remains on, it means that the
charging system is experiencing a problem. See your
local authorized dealer to obtain SERVICE IMMEDI-
ATELY.
7. Electronic Throttle Control (ETC) Light
This light will turn on briefly as a bulb check
when the ignition switch is turned ON. This
light will also turn on while the engine is
running if there is a problem with the Elec-
tronic Throttle Control system.If the light comes on while the engine is running, safely
bring the vehicle to a complete stop as soon as possible,
place the gear selector in park, and cycle the ignition key.
The light should turn off. If the light remains lit with the
engine running, your vehicle will usually be drivable.
However, see your dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required. In this case, you may
experience reduced performance, an elevated/rough idle
or engine stall, and your vehicle may require towing.
Also, have the system checked by an authorized dealer if
the light does not come on during starting.
8. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.

19. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. The trip odometer shows individual trip
mileage. Refer to ªTrip Odometer Buttonº for additional
information.
NOTE:U.S. federal regulations require upon transfer of
vehicle ownership, the seller certify the mileage the
vehicle has been driven. Therefore, if the odometer
reading is changed because of repair or replacement, be
sure to keep a record of the reading before and after the
service so that the correct mileage can be determined.
On vehicles equipped with a Premium Instrument Clus-
ter, this display shows the Electronic Vehicle Information
Center (EVIC) messages when the appropriate conditions
exist. (See page 185 for more information.)Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
ªCheck Gascapº message will display in the Electronic
Vehicle Information Center (EVIC) Ð if equipped.
Tighten the fuel filler cap properly and press the odom-
eter reset 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 Malfunction Indicator Light (MIL).
(See page 387 for more information.)
Change Oil Message (Base Cluster)
Your vehicle is equipped with an engine oil change
indicator system. The ªChange Oilº message will flash in
the instrument cluster odometer for approximately 12
seconds after a single chime has sounded to indicate the

If the ABS light remains on or turns on while driving,
then the Anti-Lock portion of the brake system is not
functioning and service is required. However, the con-
ventional brake system will continue to operate normally
if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
Ignition switch is turned to the ON position, have the
light inspected by an authorized dealer. (See page 293 for
more information.)
24. Low Fuel Indicator Light
This light will turn on and a single chime will
sound when the fuel level drops to 1/8 tank. (See
page 336 for more information.)25. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD. The OBD system monitors engine
and automatic transmission control systems. The
light will turn on when the key is in the ON position
before engine start. If the light does not come on when
turning the key from OFF to ON, have the condition
checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
The Malfunction Indicator Light flashes to alert you to
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs. (See
page 387 for more information.)
