INSTRUMENT CLUSTER DESCRIPTION
1. Check Gages
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gages indicate a reading either too high or too low.
Examine the gages carefully, and follow the instructions
above for each indicated problem.
NOTE:When the ignition switch is turned to OFF, the
Fuel Gage, Voltmeter, Oil Pressure and Engine Coolant
Temperature gages may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltage Gauge
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. Ifthe pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the “Check Gages” indicator will illuminate
and a single chime will sound. The “Check Gages”
indicator may also illuminate prior to the voltage gauge
moving out of normal range. In either case, see you local
authorized Dealer for system service.

mountain grades, in heavy traffic, or when towing a
trailer. If the needle rises to the “245°F” mark, stop the
vehicle, shift into N (Neutral), and increase the engine
idle speed for 2 to 3 minutes. If the temperature reading
does not return to normal, shut your engine OFF and
allow it to cool. Seek authorized service immediately. See
Cooling System information in the section on “Maintain-
ing Your Vehicle.”

Warning Lamp” in the instrument cluster
comes on when the ignition switch is turned to
the “ON” position as a bulb check. It should go out with
the engine running. If the “ESP/BAS Warning Lamp”
comes on continuously with the engine running, a mal-
function has been detected in the ESP system. If this light
remains on after several ignition cycles, and the vehicle
has been driven several miles at speeds greater than 30
mph (48 km/h), see your authorized dealer as soon as
possible. NOTE:•TheESP/BAS Warning Lampcome
on momentarily each time the ignition switch is turned
ON.•The ESP Control System will make buzzing or
clicking sounds when it is actively operating.25. Low Washer Fluid Light

below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled.
26. Electronic Stability Program (ESP) Indicator Light
— If Equipped
This lamp indicates the ESP system is active
when it is flashing or that a part, or all, of the
features of the ESP system are not able to
function when it is on solid. The yellow “ESP
Indicator Light” located in the tachometer area. The
ESP/TCS Indicator Lightstarts to flash as soon as the
tires lose traction and the ESP system becomes active. The
ESP/TCS Indicator Lightalso flashes when TCS is
active. If theESP/TCS Indicator Lightbegins to flash
during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions. The “ESP/
234 UNDERSTANDING YOUR INSTRUMENT PANEL

TCS Indicator Light” becomes illuminated when the
ESP-Off button has been pressed or ESP is only partially
available.
27. Transmission Oil Temperature Warning Light
(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

symbol will light and a single chime will sound.
(See page 182 for more information.)
NOTE:If your vehicle is equipped with an overhead
console module (CMTC), it is possible for DTE to display
“LO FUEL” before the low fuel warning light turns on in
the instrument cluster. This could occur because the low
fuel warning is set to a specified fuel tank volume and
DTE is an estimated distance calculation based on vehicle
fuel economy and remaining fuel tank volume.
Ram fuel tank volumes are as follows:
•26 gallons - 1500 short box models
•34 gallons - 1500/2500/3500 short box models
•35 gallons - 1500/2500/3500 long box models
