bulb DODGE RAM 4500 CHASSIS CAB 2009 4.G Owners Manual

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 Vehicle Security 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.
NOTE:
•The Sentry KeyImmobilizer System is not compat-
ible with some aftermarket remote starting systems. Use of these systems may result in vehicle starting
problems and loss of security protection.
•Exxon/Mobil Speedpass™, additional Sentry Keys
,
or any other transponder-equipped components on
the same key chain will notcause a key-related
(transponder) fault unless the additional part is physi-
cally held against the ignition key being used when
starting the vehicle. Cell phones, pagers, or other
Radio Frequency (RF) electronics will not cause inter-
ference with this system.
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

Airbag Warning Light
The airbag warning light should come on, and remain on,
for six to eight seconds as a bulb check when the ignition
switch is first turned ON. If the light is not lit during
starting, see your authorized dealer. If the light stays on,
flickers or comes on while driving, have the system
checked by an authorized dealer. If there is a problem
with the airbag warning light, the seat belt light will
flash.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for tread wear or uneven wear patterns.
Check for stones, nails, glass or other objects lodged in
the tread.
Inspect for tread cuts or sidewall cracks. Check wheel
nuts for tightness and tires for proper pressure.
Lights
Check the operation of all exterior lights. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for positive closing, latching and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
water, oil, or other fluid leaks. Also, if fuel fumes are
detected the cause should be located and corrected.

Turn Signals
Move the lever up or down to signal a right-hand or
left-hand turn.
The arrow on either side of the instrument cluster flashes
to indicate the direction of the turn, and proper operation
of the front and rear turn signal lights. If a defective bulb
or wiring circuit is detected for the turn signal system, the
arrow indicators will flash at a faster rate. If an indicator
fails to light when the lever is moved, it would suggest
that the switch or indicator lamp is defective.
You can signal a lane change by moving the lever
partially up or down.
Turn Signal Auto-Mode
Tap the multifunction lever once and the turn signal (left
or right) will flash three times, and automatically turn off.

4. 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.
5. Airbag Warning Light The indicator lights and remains lit for six to
eight seconds when the ignition is first turned
on. If the light stays on, flickers or comes on
while driving, have the airbag system checked
by an authorized dealer.
6. High Beam Indicator This indicator shows that headlights are on high
beam. 7. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will turn on for five to eight seconds as a bulb
check. During the bulb check, if the driver’s seat
belt is unbuckled, a chime will sound. After the bulb
check or when driving, if the driver seat belt remains
unbuckled, the Seat Belt Warning Light will flash or
remain on continuously. Refer to Enhanced Driver Seat
Belt Reminder System (BeltAlert) under “Occupant
Restraints” in section 2.
8. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour.

18. Malfunction Indicator Light (MIL)The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system which monitors
the emissions and engine control system. 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 five 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. Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
19. 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.

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. The light will come on when the ignition is first
turned on and remain on for 15 seconds as a bulb check.
If the light does not come on during starting, have the
system checked by an authorized dealer.
22. SERV 4WD IndicatorThe 4WD indicator will be illuminated when-
ever the 4WD mode is engaged for either the
manual or electric shift 4WD systems. The
SERV 4WD indicator monitors the electric shift
4WD system. If the SERV 4WD light stays on or comes on
during driving, it means that the 4WD system is not
functioning properly and that service is required. 23. Transmission Temperature Indicator (Automatic
Transmissions Only)
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel drive
operation (e.g., snow plowing, off-road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
24. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.
25. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Towing Tips — Automatic Transmission
The “DRIVE” range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, the
“TOW HAUL” or “OD/OFF” range should be selected.
NOTE: Using the “TOW HAUL” or “OD/OFF” range
while operating the vehicle under heavy operating con-
ditions will improve performance and extend transmis-
sion life by reducing excessive shifting and heat build up.
This action will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to the “Main-
tenance Schedule” in Section 8 of this manual for proper
maintenance intervals.
