instrument panel Ram 3500 Chassis Cab 2017 Repair Manual

If brake failure is indicated, immediate repair is necessary.
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 a
collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force
Distribution (EBD).
CAUTION!
In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immedi-
ate repair to the ABS system is required. Operation of the Brake Warning Light can be checked by
placing the ignition in the ON/RUN position. The light
should illuminate for approximately 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 placed in the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.

Red Telltale Light What It Means
Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15 seconds when the vehicle security alarm is
arming, and then will flash slowly until the vehicle is disarmed.

Engine Temperature Warning Light
Red WarningLight What It Means
Engine Temperature Warning Light
This light warns of an overheated engine condition. As engine coolant temperatures rise and the
gauge approaches
H, this indicator will illuminate and a single chime will sound after reaching a
set threshold. Further overheating will cause a continuous chime sound for 4 minutes, or until
the engine is allowed to cool, whichever comes first.
If the light turns on while driving, safely pull over and stop the vehicle. If the A/C system is on,
turn it off. Also, shift the transmission into NEUTRAL and idle the vehicle. If the temperature
reading does not return to normal, turn the engine off immediately and call for service. Refer to
“If Your Engine Overheats” in “What To Do In Emergencies” for further information.
Battery Charge Warning Light
Red Telltale Light What It Means
Battery Charge Warning Light
This light illuminates when the battery is not charging properly. If it stays on while the engine is
running, there may be a malfunction with the charging system. Contact your authorized dealer as
soon as possible. This indicates a possible problem with the electrical system or a related compo-
nent.

Oil Pressure Warning Light
Red TelltaleLight What It Means
Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop the vehicle
and shut off the engine as soon as possible. A chime will sound 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.
Electronic Throttle Control (ETC) Warning Light
Red Telltale
Light What It Means
Electronic Throttle Control (ETC) Warning Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system. If a prob-
lem is detected while the engine is running, the light will either stay on or flash depending on
the nature of the problem. Cycle the ignition key when the vehicle is safely and completely
stopped and the transmission is placed in the PARK position. The light should turn off. If the
light remains on with the engine running, your vehicle will usually be drivable; however, see an
authorized dealer for service as soon as possible.
If the light continues to flash 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. The light will come on when the ignition is first placed in the ON/RUN 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.

Yellow Telltale Indicator Lights
Engine Check/Malfunction Indicator Light (MIL)
Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic System
called OBD II that monitors engine and automatic transmission control systems. The light will
illuminate when the ignition is in the ON/RUN position before engine start. If the bulb does not
come on when turning the key from OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor quality fuel, etc., may illuminate the
light after engine start. The vehicle should be serviced if the light stays on through several typical
driving styles. In most situations, the vehicle will drive normally and will not require towing.
When the engine is running, the MIL may flash to alert serious conditions that could lead to im-
mediate loss of power or severe catalytic converter damage. The vehicle should be serviced as
soon as possible if this occurs.

WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you drive
slowly or park over flammable substances such as dry
plants, wood, cardboard, etc. This could result in death
or serious injury to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the vehicle
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.

Electronic Stability Control (ESC) Indicator Light — If Equipped
Yellow TelltaleLight What It Means
Electronic Stability Control (ESC) Indicator Light — If Equipped
The “ESC Indicator Light” in the instrument cluster will come on when the ignition is placed in
the ON/RUN position, and when ESC is activated. It should go out with the engine running. If
the “ESC Indicator Light” comes on continuously with the engine running, a malfunction has
been detected in the ESC system. If this light remains on after several ignition cycles, and the ve-
hicle has been driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to have the problem diagnosed and corrected.
•
The “ESC Off Indicator Light” and the “ESC Indicator Light” come on momentarily each
time the ignition is placed in the ON/RUN position.
• Each time the ignition is turned to ON/RUN, the ESC system will be on, even if it was turned
off previously.
• The ESC system will make buzzing or clicking sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive.
• This light will come on when the vehicle is in an ESC event.

Tire Pressure Monitoring System (TPMS) Warning Light
Yellow TelltaleLight What It Means
Tire Pressure Monitoring System (TPMS) Warning Light
The warning light switches on and a message is displayed to indicate that the tire pressure is
lower than the recommended value and/or that slow pressure loss is occurring. In these cases,
optimal tire duration and fuel consumption may not be guaranteed.
Should one or more tires be in the condition mentioned above, the display will show the indica-
tions corresponding to each tire in sequence.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Repair immedi-
ately using the dedicated tire repair kit and contact
your authorized dealer as soon as possible.
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.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.
