check engine light Ram 1500 2009 Owner's Manual

The system uses ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off in two
seconds if someone uses an invalid key to try to start the
engine.
NOTE:A key that has not been programmed is also
considered an invalid key.
During normal operation, after turning on the ignition
switch, the Vehicle Security Light will turn on for three
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
key to try to start the engine. Either of these conditions
will result in the engine being shut off after two seconds. If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10 sec-
onds), it indicates that there is a fault in the electronics.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer.
NOTE:
The Sentry Key Immobilizer System is not
compatible with some aftermarket remote starting sys-
tems. Use of these systems may result in vehicle starting
problems and loss of security protection.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE: Only keys that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Sentry Key is programmed to a vehicle, it cannot
be programmed to any other vehicle.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

VEHICLE SECURITY ALARM — IF EQUIPPED
The Vehicle Security Alarm monitors the vehicle doors
and ignition for unauthorized operation. When the Ve-
hicle Security Alarm is activated, the system provides
both audible and visible signals. For the first three
minutes the horn will sound and the headlights, park
lamps and/or turn signals will flash and Vehicle Security
Light will flash repeatedly. For an additional 15 minutes
only, the headlights, park lamps and/or turn signals and
Vehicle Security Light will flash. The engine will run only
if a valid Sentry Keyis used to start the vehicle. Use of
the Sentry Key will disable the alarm.
Rearming of the System
The Vehicle Security Alarm will rearm itself after the 15
additional minutes of headlights and Vehicle Security
Light flashing, if the system has not been disabled. If the
condition which initiated the alarm is still present, the
system will ignore that condition and monitor the re-
maining doors and ignition.
To Set the Alarm
The Vehicle Security Alarm will set when you use the
power door locks, or use the Remote Keyless Entry (RKE)
transmitter to lock the doors. After all the doors are
locked and closed, the Vehicle Security Light in the
instrument cluster will flash rapidly to signal that the
system is arming. The Vehicle Security Light in the
instrument panel cluster will flash rapidly for about
16 seconds to indicate that the alarm is being set. After
the alarm is set, the Vehicle Security Light will flash at a
slower rate to indicate that the system is armed.
NOTE:If the Vehicle Security Light stays on continu-
ously during vehicle operation, have the system checked
by an authorized dealer.
To Disarm the System
Use the RKE transmitter to unlock the door. If something
has triggered the system in your absence, the horn will
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

sound three times when you unlock the doors and the
Vehicle Security Light will flash for 30 seconds. Check the
vehicle for tampering.
The Vehicle Security Alarm will also disarm if the vehicle
is started with a programmed Sentry Key. If an unpro-
grammed Sentry Keyis used to start a vehicle, the
engine will run for two seconds and then the alarm will
be initiated. To exit the alarming mode, press the RKE
transmitter UNLOCK button, or start the vehicle with a
programmed Sentry Key.
The Vehicle Security Alarm is designed to protect your
vehicle; however, you can create conditions where the
system will arm unexpectedly. If you remain in the
vehicle and lock the doors with the RKE transmitter, the
alarm will sound when you pull the door handle to exit.
The door will be locked, but the Vehicle Security Alarm
will not arm.ILLUMINATED ENTRY SYSTEM — IF EQUIPPED
The courtesy lights will turn on when you use the
Remote Keyless Entry (RKE) transmitter or open the
doors. This feature is only available if you have Remote
Keyless Entry.
The lights will fade to off after approximately 30 seconds,
or they will immediately fade to off once the ignition
switch is turned ON.
NOTE:
•The front courtesy overhead console and door cour-
tesy lights do not turn off if the dimmer control is in
the interior lights ON position (extreme right posi-
tion).
•The illuminated entry system will not operate if the
dimmer control is in the extreme left position.

WARNING! (Continued)
•Do not attempt to modify any part of your ad-
vanced airbag system. The airbag may inflate
accidentally or may not function properly if modi-
fications are made. Take your vehicle to an autho-
rized dealer for any advanced airbag system ser-
vice. If your seat, including your trim cover and
cushion, needs to be serviced in any way (includ-
ing removal or loosening/tightening of seat attach-
ment bolts), take the vehicle to your authorized
dealer. Only manufacturer approved seat accesso-
ries may be used. If it is necessary to modify an
advanced airbag system for persons with disabili-
ties, contact your authorized dealer.
Airbag Warning Light
You will want to have the airbags ready to
inflate for your protection in a collision. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system immediately.
•The Airbag Warning Light does not come on for
approximately six to eight seconds when the ignition
switch is first turned ON.
•The light remains on after the approximate four to
six-second interval.
•The light comes on and remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The airbags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

INSTRUMENT CLUSTER DESCRIPTION
1. Tachometer
The Tachometer indicates engine speed in revolutions per
minute.
CAUTION!
Do not operate the engine with the tachometer
pointer at high RPM for extended periods. Engine
damage may occur.
2. Turn Signal Indicators The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
NOTE:
•A continuous chime will sound if the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on.
•Check for an inoperative outside light bulb if either
indicator remains on and does not flash, or flashes at a
rapid rate.
3. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.
4. 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.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.

7. Electronic Throttle Control (ETC) LightThis light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned ON and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the shift lever is
placed in the PARK position, the light should turn off.
If the light remains lit with the engine running, your
vehicle will usually be drivable; however, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required and you may experience reduced performance,
an elevated/rough idle or engine stall and your vehicle
may require towing. For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle Information
Center (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” in this section for more
information.
8. 4WD Indicator
This light indicates the vehicle is in four-wheel
drive and 4LOCK. 4WD allows all four wheels
to receive torque from the engine simulta-
neously.
9. 4WD Auto Indicator The 4WD auto indicator will be illuminated
whenever the four-wheel drive mode is auto-
matically engaged.

21. Voltmeter
When the engine is running, the gauge indicates the
electrical system voltage. The pointer should stay within
the normal range if the battery is charged. If the pointer
moves to either extreme left or right and remains there
during normal driving, the electrical system should be
serviced.
NOTE:
•If the gauge pointer moves to either extreme of the
gauge, the “Check Gauges” indicator will illuminate
and a single chime will sound.
•The voltmeter may show a gauge fluctuation at vari-
ous engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of
the cycling operation is controlled by the enginecontrol module. Post-heat operation can run for sev-
eral minutes, and then the electrical system and volt-
meter needle will stabilize.
22. Cargo Light The cargo light will illuminate when the cargo
light is activated by pressing the cargo light
button on the headlight switch.
23. Brake Warning Light This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the Anti-lock Brake System reservoir.

Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON position. The light should illuminate for approxi-
mately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is detected.
If the light does not illuminate, have the light inspected
by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
24. Oil Pressure Warning Light This light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns
on. Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle Information
Center (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” in this section for more
information.
25. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly, when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
NOTE: The TPMS telltale is also accompanied by a
“Low Tire” message in the odometer (Base Cluster), or in
the Electronic Vehicle Information Center (EVIC) screen
indicating “Low Tire” for EVIC enabled clusters. 26. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic (OBDII) system which
monitors the emissions and engine control sys-
tem. If the vehicle is ready for emissions testing, the light
will come on when the ignition is first turned on and
remain on, as a bulb check, until the engine is started. If
the vehicle is not ready for emissions testing the light will
come on when the ignition is first turned on and remain
on for 15 seconds, then blink for 5 seconds, and remain
on until the vehicle is started. If the bulb does not come
on during starting, have the condition investigated
promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
