Ram 2500 2016 Diesel Supplement

NOTE:
•The gauge may take up to five seconds to update after
adding a gallon or more of Diesel Exhaust Fluid (DEF)
to the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See
your authorized dealer for service.
• The DEF gauge may also not immediately update after
a refill if the temperature of the DEF fluid is below 12F
(-11C). The DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update after a period
of run time. Under very cold conditions, it is possible
that the gauge may not reflect the new fill level for
several drives. •
Outside temperature can affect DEF consumption. In
cold conditions, 12° F (-11° C) and below, the DEF
gauge needle can stay on a fixed position and may not
move for extended periods of time. This is a normal
function of the system.

1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Engine Coolant Temperature •This gauge shows the engine coolant temperature.
The gauge pointer will likely show higher tempera-
tures when driving in hot weather, up mountain
grades, or in heavy stop and go traffic. If the red
Warning Light turns on while driving, safely bring
the vehicle to a stop, and turn off the engine. DO
NOT operate the vehicle until the cause is corrected.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
(Continued)
CAUTION! (Continued)
drops back into the normal range. If the pointer
remains on the “H”, turn the engine off immediately
and call an authorized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle.” Follow the warnings under the “Cooling
System Pressure Cap” paragraph.

3. Oil Pressure Gauge•The pointer should always indicate some oil pres-
sure when the engine is running. A continuous high
or low reading under normal driving conditions may
indicate a lubrication system malfunction. Immedi-
ate service should be obtained from an authorized
dealer.
4. Speedometer •Indicates vehicle speed.
5. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position. 6. Driver Information Display (DID)
•When the appropriate conditions exist, this display
shows the Driver Information Display (DID) mes-
sages. Refer to “Driver Information Display” in
“Understanding Your Instrument Panel” for further
information.
7. DEF Gauge •The DEF Gauge displays the actual level of Diesel
Exhaust Fluid in the DEF tank. Diesel Exhaust Fluid
(DEF) is required to maintain normal vehicle opera-
tion and emissions compliance. If something is
wrong with the gauge, a DEF Warning Message or
Malfunction Indicator Light (MIL) will be displayed.
More information is available in the Electronic Ve-
hicle Information (EVIC) or Driver Information Dis-
play (DID) section under the heading of Diesel
Exhaust Fluid (DEF) Warning Messages.

IMPORTANT: The warning / indicator light switches on
in the instrument panel together with a dedicated mes-
sage and/or acoustic signal when applicable. These
indications are indicative and precautionary and as such
must not be considered as exhaustive and/or alternative
to the information contained in the Owner Manual,
which you are advised to read carefully in all cases.
Always refer to the information in this chapter in the
event of a failure indication.
All active telltales will display first if applicable. The
system check menu may appear different based upon
equipment options and current vehicle status. Some
telltales are optional and may not appear.

Seat Belt Reminder Warning Light
Red TelltaleLight What It Means
Seat Belt Reminder Warning Light
When the ignition switch is first turned to ON/RUN, this light will turn on for four 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 un-
buckled, the Seat Belt Reminder Light will flash or remain on continuously and a chime will
sound. Refer to “Occupant Restraints” in “Things To Know Before Starting Your Vehicle” for
further information.

Air Bag Warning Light
This light will turn on for four to eight seconds as a bulb check when the ignition switch is
first turned to ON/RUN. If the light is either not on during starting, stays on, or turns on
while driving, have the system inspected at an authorized dealer as soon as possible. This
light will illuminate with a single chime when a fault with the Air Bag Warning Light has
been detected, it will stay on until the fault is cleared. If the light comes on intermittently or
remains on while driving, have an authorized dealer service the vehicle immediately. Refer
to “Occupant Restraints” in “Things To Know Before Starting Your Vehicle” for further infor-
mation.

Brake Warning Light
Red TelltaleLight What It Means
United States
Canada
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 reser-
voir.
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 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.
26 UNDERSTANDING YOUR INSTRUMENT PANEL

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
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 an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.
