2009 DODGE RAM 2500 DIESEL ABS

Vehicle Security Alarm 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 Vehicle Security
Alarm is armed.
NOTE:If the Vehicle Security Light stays on continu-
ously during vehicle operation, have the Vehicle Security
Alarm checked by an authorized dealer.To Disarm the SystemUse the RKE transmitter to unlock the door. If something
has triggered the Vehicle Security Alarm in your absence,
the horn will sound three times when you unlock the
doors and the Vehicle Security Light will flash for 30 sec-
onds. 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 Key
is used to start a vehicle, the
engine will run for two seconds and then the Security
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
Vehicle Security Alarm 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.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 19

18. Malfunction Indicator Light (MIL)The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBD II, that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON position, before engine start. If the bulb 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 MIL 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.
If the MIL flashes when the engine is running, serious
conditions may exist 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. 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.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Program (ESP) sys-
tem. In this case, the light will remain on until the
condition has been corrected. If the problem is related to
the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during
each stop.194 UNDERSTANDING YOUR INSTRUMENT PANEL

The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
an accident. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
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.
20. Anti-Lock Brake (ABS) Light This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional 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. 21. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. 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 authorized dealer for service as soon as possible. If
the light is flashing when the engine is running, imme-
diate 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
briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.196 UNDERSTANDING YOUR INSTRUMENT PANEL

12. Check wire rope. The wire rope should be neatly
wound around the spooling drum. Improper winding
can cause damage to the wire rope.13. In certain situations you
may decide to throw a heavy
blanket or similar object over
the wire rope. A heavy blan-
ket can absorb energy should
the wire rope break. Place it
on the wire rope midway be-
tween the winch and the an-
chor point. Do this before the
wire rope is put under ten-
sion. Do not approach or move the blanket once tension
is applied. Do not allow it to get pulled into the fairlead.
If it is necessary to move or remove the blanket, slack the
tension on the wire rope first.
14. Establish \bno people\b zones:Make your intentions
clear. Be sure that everyone in the immediate vicinity
surrounding the winching operation is completely aware
of your intentions before you pull. Declare where the
spectators should not stand - never behind or in front of

If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still func-
tion with some loss of overall braking effectiveness. This
will be evident by increased pedal travel during applica-
tion, greater pedal force required to slow or stop, and
activation of the “Brake Warning Light” and the “ABS
Warning Light” (If Equipped) during brake use.3500 Dual Rear Wheel Models OnlyThe brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
system. You may experience some clicking or hissing
noises from the hydro-boost system during hard braking
conditions.
NOTE:Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid reaches
operating temperature.
Four-Wheel Anti-Lock Brake System
WARNING!
The Four-Wheel Anti-Lock Brake System contains
sophisticated electronic equipment. It may be sus-
ceptible to interference caused by improperly in-
stalled or high output radio transmitting equipment.
This interference can cause possible loss of anti-lock
braking capability. Installation of such equipment
should be performed by qualified professionals.
The Four-Wheel Anti-lock Brake System (ABS) is de-
signed to aid the driver in maintaining vehicle control
under adverse braking conditions. The system operates
with a separate computer to modulate hydraulic pressure
to prevent wheel lockup and help avoid skidding on
slippery surfaces.
STARTING AND OPERATING 331

The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation. This is
normal.
The ABS conducts a low-speed selftest at about 10 mph
(16 km/h). If you have your foot lightly on the brake
while this test is occurring, you may feel slight pedal
movement. The movement can be more apparent on ice
and snow. This is normal.
The ABS pump motor runs during the self-test at 10 mph
(16 km/h) and during an ABS stop. The pump motor
makes a low humming noise during operation. This is
normal.
When you are in a severe braking condition involving
use of the ABS, you will experience some pedal drop as
the vehicle comes to a complete stop. This is the result of
the system reverting to the base brake system and is
normal.Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal, and indicate that the
system is functioning.
ABS Warning LightThe ABS includes an amber warning light. When the light
is illuminated, the ABS is not functioning. The system
reverts to standard, non-anti-lock brakes.
WARNING!
•
Pumping of the anti-lock brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.
