2012 RAM CHASSIS CAB light

The key symbol indicates that this outlet can supply
power when the key is in the ON or ACC positions.
All accessories connected to the outlet(s) should be
removed or turned off when the vehicle is not in use to
protect the battery against discharge.
WARNING!To avoid serious injury or death:
• Only devices designed for use in this type of
outlet should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving
the vehicle.
• If this outlet is mishandled, it may cause an
electric shock and failure.Power Outlet Fuse Locations1 — M7 Fuse 20 A Yellow Power Outlet Center Seat (Opt) or

CAUTION!• Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not in
use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
• Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these inter-
mittently and with greater caution.
• After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle’s battery. CIGAR LIGHTER AND ASH RECEIVER — IF
EQUIPPED
A removable ash receiver and cigar lighter are available.
For vehicles with a bench seat the cupholder tray can be
used to hold the ash receiver.

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
The Tachometer indicates engine speed in revolutions per
minute (RPM x 1000).
CAUTION!Do not operate the engine with the tachometer
pointer at high RPM for extended periods. Engine
damage may occur.
2. Turn Signal Indicators
The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
NOTE:
• A continuous chime will sound if the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on. • Check for an inoperative outside light bulb if either
indicator flashes at a rapid rate.
3. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON/RUN position.
4. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.

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
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealership 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-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see “Main-
taining Your Vehicle”. Follow the warnings under the
Cooling System Pressure Cap paragraph.
5. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour (mph/km/h).
6. 4 LOW
This light alerts the driver that the vehicle is in
the four-wheel drive LOW mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to190 UNDERSTANDING YOUR INSTRUMENT PANEL

rotate at the same speed. Low range provides a greater
gear reduction ratio to provide increased torque at the
wheels.
7. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned to 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.
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 autho-
rized dealer for service as soon as possible. If the light is
flashing 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.
For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle Information
Center (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” for further information.
8. 4WD Indicator
This light indicates the vehicle is in four-wheel
drive and 4LOCK. 4WD allows all four wheels
to receive torque from the engine simultane-
ously.
9. SVC (Service) 4WD
The SVC 4WD light monitors the electric shift
four-wheel drive system. If the SVC 4WD light
stays on or comes on during driving, it means
that the four-wheel drive system is not func-
tioning properly and that service is required. 4 UNDERSTANDING YOUR INSTRUMENT PANEL 191

For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle Information
Center (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” for further information.
10. TOW/HAUL
The TOW HAUL button is located on the
center stack switch bank. This light will illumi-
nate when TOW HAUL mode is selected
11. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed. 12. Oil Pressure Gauge — If Equipped
The pointer should always indicate some oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate a
lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
13. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.
14. Odometer Display / Electronic Vehicle Information
Center (EVIC) Display Area
Odometer Display
The odometer display shows the total distance the ve-
hicle has been driven. Regulations require that upon
transfer of vehicle ownership, the seller certify to the
purchaser the correct mileage that the vehicle has been
driven. If your odometer needs to be repaired or serviced,192 UNDERSTANDING YOUR INSTRUMENT PANEL

engine hours will be displayed for a period of 30 seconds
until the ignition is turned OFF or the engine is started.
Some of the above warnings will be displayed in the
Electronic Vehicle Information Center (EVIC) Display
Area located in the instrument cluster. Refer to ”Elec-
tronic Vehicle Information Center (EVIC) — If Equipped”
for further information.
gASCAP
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
loose gascap indicator or the message “gASCAP” will
display in the odometer display area. Tighten the fuel
filler cap properly and press the TRIP button to turn off
the message. If the problem continues, the message will
appear the next time the vehicle is started.
A loose gas cap indicator will display in the Electronic
Vehicle Information Center (EVIC) for the premium cluster (Refer to ”Electronic Vehicle InformationCenter
(EVIC) — If Equipped” for further information).
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
noFUSE
If the vehicle diagnostic system determines that the
Ignition Off Draw (IOD) fuse is improperly installed, or
damaged, a “noFUSE” message will display in the odom-
eter display area. For further information on fuses and
fuse locations refer to “Fuses” in “Maintaining Your
Vehicle”.
CHANgE OIL
Your vehicle is equipped with an engine oil change
indicator system. The CHANgE OIL message will flash
in the instrument cluster odometer for approximately
12 seconds after a single chime has sounded to indicate
the next scheduled oil change interval. The engine oil
change indicator system is duty cycle-based, which194 UNDERSTANDING YOUR INSTRUMENT PANEL
