ELECTRICAL POWER OUTLETS
The auxiliary electrical outlet can provide power for in
cab accessories designed for use with the standard “cigar
lighter” plug. The outlet is located in the instrument
panel below and to the right of the Climate Control
Panel. A cap is attached to the outlet base indicating
“Power Outlet” 12V-20A.Compass Variance Map UNDERSTANDING THE FEATURES OF YOUR VEHICLE 149

There is an additional Power Outlet inside the center
console of vehicles equipped with 40/20/40, or Bucket
front seats. There is also a Power Outlet located on the
rear of the center console for Quad Cab or Mega Cab
vehicles (only) equipped with bucket seats.
The outlet(s) has/have a fused direct feed from the
battery so it/they receive power whether the ignition is
ON or OFF.
All accessories connected to this/these outlet(s) should
be removed or turned OFF when the vehicle is not in use
to protect the battery against discharge.
NOTE: If desired, all of the power outlets can be
converted by your authorized dealer to provide power
with the ignition switch in the ON position only. CAUTION!Electrical Outlet Use With Engine Off
• 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 engine 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.150 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

CIGAR LIGHTER AND ASH RECEIVER
The removable ash receiver is located in the instrument
panel cup holder tray.
The cigar lighter is located on the instrument panel,
above and to the left of the ash receiver.
As a child safety precaution, the lighter only operates
with the ignition switch ON. It heats when pushed in and
pops out automatically when ready for use. To preserve
the heating element, do not hold the lighter in the
heating position. Ash Tray Automatic Transmission UNDERSTANDING THE FEATURES OF YOUR VEHICLE 151

configure the storage area into compartments. For ex-
ample, compartments can be configured to hold a lap-top
computer, a cellular telephone, CD’s and miscellaneous
items. The top of the cover provides a generous firm
surface to serve as a desktop for your “mobile office.”
WARNING!• This armrest is not a seat. Anyone seated on the
armrest could be seriously injured during vehicle
operation, or an accident. Only use the center
seating position when the armrest is fully upright.
• In an accident, the latch may open if the total
weight of the items stored exceeds about 10 lbs
(4.5 kg). These items could be thrown about
endangering occupants of the vehicle. Items
stored should not exceed a total of 10 lbs (4.5 kg). 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

Located in the center of the front 40/20/40 seat cushion
there is a storage compartment.
Standard cab models also have storage behind the seat.
The Quad Cab models provide additional storage under
the rear seat. Lift the seat to access the storage compart-

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. Voltmeter
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. If the 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.
NOTE:
• The voltmeter may show a gauge fluctuation if certain
engine temperatures are below 66°F (19°C). This cy-
cling operation is caused by the post-heat cycle of the
intake manifold heater system. The number of cycles
and the length of the cycling operation is controlled by
the engine control module, this time will not exceed
150 seconds. The needle should then stabilize at the
approximate operation point.
• The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a noticeable
reduction in blower motor speed.172 UNDERSTANDING YOUR INSTRUMENT PANEL

3. Turn Signal Indicators
Lights in instrument cluster flash when outside turn
signals are operating.
4. Tachometer
The tachometer indicates engine speed in revolutions per
minute.
CAUTION!Do not operate the engine with the tachometer
pointer at high rpm for extended periods. Engine
damage may occur.
5. Airbag Indicator Light
The indicator lights and remains lit for 6 to 8 seconds
when the ignition is first turned on. If the light stays on,
flickers or comes on while driving, have the airbag
system checked by an authorized dealer. 6. High Beam Indicator
This indicator shows that headlights are on high
beam.
7. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will turn on for 5 to 8 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 unbuckled,
the Seat Belt Warning Light will flash or remain on
continuously. Refer to  Enhanced Driver Seat Belt Re-
minder System (BeltAlert™)  in the Occupant Restraints
section for more information. (See page 34 for more
information.)
8. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour. UNDERSTANDING YOUR INSTRUMENT PANEL 173

9. 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. (See page 398 for more
information.)
NOTE: If the gauge pointer moves to either extreme of
the gauge, the “Check Gages” indicator will illuminate
and a single chime will sound.
10. Transfer Case Position
(See page 283 for more information.)
11 . TOW HAUL
The TOW HAUL button is located at the end of the gear
shift lever. This light will illuminate when the TOW
HAUL OD/OFF button is pushed once. (See page 271 for
more information.) 12. OD/OFF
the OD/OFF button is located at the end of the gear shift
lever. This light will illuminate when the TOW HAUL
OD/OFF button is pushed twice. (See page 271 for more
information.)
13. Temperature Gauge
The temperature gauge indicates engine coolant
temperature. Any reading within the normal
range indicates that the cooling system is operat-
ing satisfactorily. The gauge needle will likely indicate a
higher temperature when driving in hot weather, up
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.”174 UNDERSTANDING YOUR INSTRUMENT PANEL
