2018 Ram 3500 Chassis Cab brake light

Daytime Running Lights (DRL) — If Equipped
The headlights on your vehicle will illuminate when the
engine is started and the transmission is in any gear except
PARK. This provides a constantlights oncondition until
the ignition is turned OFF. The lights illuminate at less than
half of normal intensity. If the parking brake is applied, the
Daytime Running Lights (DRL) will turn off. Also, if a turn
signal is activated, the DRL lamp on the same side of the
vehicle may turn off for the duration of the turn signal
activation. Once the turn signal is no longer active, the DRL
lamp will illuminate.
Multifunction Lever
The multifunction lever is located on the left side of the
steering column.
High/Low Beam Switch
Push the multifunction lever toward the instrument panel
to switch the headlights to high beam. Pulling the multi-
function lever back toward the steering wheel will turn the
low beams back on, or shut the high beams off.
Automatic High Beam Headlamp Control — If
Equipped
The Automatic High Beam Headlamp Control system
provides increased forward lighting at night by automat-
ing high beam control through the use of a digital camera
mounted on the inside rearview mirror. This camera de-
tects vehicle specific light and automatically switches from
high beams to low beams until the approaching vehicle is
out of view.

The instrument cluster display screens are located in the
center portion of the cluster and consists of eight sections:
1. Main Screen — The inner ring of the display willilluminate in grey under normal conditions, yellow for
non critical warnings, red for critical warnings, and
white for on demand information.
2. Audio / Phone Information and Submenu Information — Whenever there are submenus available, the position
within the submenus is shown here.
3. Selectable Information (Compass, Outside Temp, Range to Empty, Trip A, Trip B, Average Fuel Economy, Trailer
Trip (distance only), Trailer Brake Gain, Time)
4. Telltales/Indicators
5. Gear Selector Status
6. Selectable Menu Icons
7. 4WD Status
8. Selectable Gauge 2 (Trans Temp, Oil Temp, Oil Life, Trailer Brake, Current Fuel Economy)
9. Selectable Gauge 1 (Trans Temp, Oil Temp, Oil Life, Trailer Brake, Current fuel economy) The instrument cluster display area will normally display
the main menu or the screens of a selected feature of the
main menu. The main display area also displays “pop up”
messages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories:
•
Five Second Stored Messages
When the appropriate conditions occur, this type of mes-
sage takes control of the main display area for five seconds
and then returns to the previous screen. Most of the
messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. As long as
there is a stored message, an “i” will be displayed in the
instrument cluster display’s compass/outside temp line.
Examples of this message type are “Right Front Turn Signal
Lamp Out” and “Low Tire Pressure.”
• Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle).

WARNING LIGHTS AND MESSAGES
Red Warning Lights
— Seat Belt Reminder Warning Light
This light indicates when the driver or passenger seat belt
is unbuckled. When the ignition is first placed in the
ON/RUN or ACC/ON/RUN position and if the driver ’s
seat belt is unbuckled, a chime will sound and the light will
turn on. When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime will sound.
Refer to “Occupant Restraints Systems” in “Safety” for
further information.
— Air Bag Warning Light
This light indicates a fault with the air bag, and will turn on
for four to eight seconds as a bulb check when the ignition
is placed in the ON/RUN or ACC/ON/RUN position. This light will illuminate with a single chime when a fault
with the air bag has been detected, it will stay on until the
fault is cleared. If the light is either not on during startup,
stays on, or turns on while driving, have the system
inspected at an authorized dealer as soon as possible.
— 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 Control (ESC) system.
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.
The dual brake system provides a reserve braking capacity
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 conditions.
The vehicle should have service performed, and the brake
fluid level checked.
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). 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/RUN position. The light should illuminate for ap-
proximately 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 your authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch 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.
— 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 Coolant Temperature Warning Light
This light warns of an overheated engine condition. If the
engine coolant temperature is too high, this indicator will
illuminate and a single chime will sound. If the tempera-
ture reaches the upper limit, a continuous chime will be
sound for four minutes or until the engine is able 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
