storage area into separate compartments. Lift the lower
handle on the front of the armrest, and raise the armrest
for access to the lower storage bin. On Quad Cab and
Mega Cab models the rear of the floor console offers a
power outlet, a tip out bin and a rear air duct (Mega Cab
Only).
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
discharge sufficiently to degrade battery life
and/or prevent engine starting.
•Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will degrade 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.

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 isunbuckled, 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 toEnhanced Driver Seat Belt Re-
minder System (BeltAlert™)in the Occupant Restraints
section for more information. (See page 30 for more
information.)
8. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour.
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 379 for more
information.)

CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
18. Brake System Warning Light
This light illuminates when the ignition key is turned to
the ON position and remains on for a few seconds. If the
light stays on longer, it may be an indication that the
parking brake has not been released. This light will
illuminate if the brake fluid is low, especially when
braking or accelerating hard. This light will illuminate if
the ABS indicator light has a malfunction. This light will
flash if the engine is running and the parking brake is on.If the light remains on when the parking brake is
released, it indicates a possible brake hydraulic system
malfunction. In this case, the light will remain on until
the cause is corrected.
If brake failure is indicated, immediate repair is necessary
and continued operation of the vehicle in this condition is
dangerous.
Acceleration which causes the rear wheels to slip for a
period of time may result in the red brake light illumi-
nating and a brake switch code being set on ABS
equipped vehicles. Depressing the brake pedal should
extinguish the red brake light.
19. ABS Warning Light
This light monitors the Anti-Lock Brake System
which is described elsewhere in this manual. This
light will come on when the ignition key is turned to the
ON position and may stay on for five seconds. If the ABS
light remains on or comes on during driving, it indicates

25. 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
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
26. Wait To Start Indicator
The Wait To Start Indicator will illuminate when
the ignition key is first turned to the ON position.
Wait until the Wait To Start Indicator turns OFF then start
the vehicle.27. Odometer/Trip Odometer Button

28. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.
29. Low Fuel Warning Light
Glows when the pointer is between “E” and 1/8
indication mark (approximately 15% of tank vol-
ume) on the fuel gauge. When the fuel gauge
pointer is on “E” (equivalent to Distance To Empty [DTE]
= 0 on the overhead console if so equipped) there is
reserve fuel capacity, which corresponds to approxi-
mately 8% of tank volume. This reserve capacity was put
in place to prevent the likelihood of customers running

254 STARTING AND OPERATING

•If the engine is started before the WAIT TO START
light turns off, the preheat cycle will turn off.
•If the engine is cranked for more than 10 seconds, the
post-heat cycle will turn off.
NOTE:Engine idle speed will automatically increase to
1000 rpm at low coolant temperatures to improve engine
warm-up.
NOTE:When a diesel engine is allowed to run out of
fuel or the fuel gels at low temperatures, air is pulled into
the fuel system.
You may try priming as described below.
1. Add a substantial quantity of fuel to the tank (5 to 10
gallons) or eliminate the gelled fuel condition.
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFFposition). The electric fuel transfer pump will continue to
run and purge air from the system for about 20 seconds.
After 20 seconds, attempt to start the engine again.
3. Start the engine using the Normal Starting Procedure.
4. Repeat the procedure if the engine does not start.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.

Starting Fluids
WARNING!
STARTING FLUIDS or flammable liquids are
NEVER TO BE USED in the Cummins Diesel (see
Warning label). Never pour diesel fuel, flammable
liquid, starting fluids (ether) into the air cleaner
canister, air intake piping, or turbocharger inlet in an
attempt to start the vehicle. This could result in a
flash fire and explosion causing serious personal
injury and engine damage.
The engine is equipped with an automatic electric air
preheating system. If the instructions in this manual are
followed, the engine should start in all conditions.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
NORMAL OPERATION
Observe the following when the engine is operating.
•All message center lights are off.
•Check Engine Lamp is off.
•Engine Oil Pressure is above 10 psi (69 kPa) at idle.
•Low Oil Pressure light is off.
258 STARTING AND OPERATING

If One or More Shift Conditions are not Met
1. The indicator light for the current position will remain
ON.
2. The newly selected position indicator light will con-
tinue to flash.
3. The transfer casewill notshift.
NOTE:Before retrying a selection, make certain that all
the necessary requirements for selecting a new transfer
case position have been met. To retry the selection, turn
the control knob back to the current position, wait five (5)
seconds, and retry selection. To find the shift require-
ments, refer to theShifting Procedurefor your transfer
case, located in this section of the owner’s manual.
The “SERVICE 4WD” warning light monitors the electric
shift 4WD system. If this light remains on after enginestart up or illuminates during driving, it means that the
4WD system is not functioning properly and that service
is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if theService 4WDlight is
illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The transfer case is not
equipped with a synchronizer and therefore the front and
rear driveshaft speeds must be equal for the shift to take
place. Shifting while only the front or rear wheels are
spinning can cause damage to the transfer case.
280 STARTING AND OPERATING

LIMITED-SLIP DIFFERENTIAL — IF EQUIPPED
The limited-slip differential provides additional traction
on snow, ice, mud, sand and gravel, particularly when
there is a difference between the traction characteristics
of the surface under the right and left rear wheels. During
normal driving and cornering, the limited-slip unit per-
forms similarly to a conventional differential. On slip-
pery surfaces, however, the differential delivers more of
the driving effort to the rear wheel having the better
traction.
The limited-slip differential is especially helpful during
slippery driving conditions. With both rear wheels on a
slippery surface, a slight application of the accelerator
will supply maximum traction. When starting with only
one rear wheel on an excessively slippery surface, slight
momentary application of the parking brake may be
necessary to gain maximum traction.WARNING!
On vehicles equipped with a limited-slip differen-
tial, never run the engine with one rear wheel off the
ground, since the vehicle may drive through the rear
wheel remaining on the ground. You could lose
control of the vehicle.
Care should be taken to avoid sudden accelerations when
both rear wheels are on a slippery surface. This could
cause both rear wheels to spin, and allow the vehicle to
slide sideways on the crowned surface of a road or in a
turn.

PARKING BRAKE
The foot operated parking brake is positioned below the
lower left corner of the instrument panel. To release the
parking brake, pull the parking brake release handle.
NOTE:The instrument cluster red brake warning light
will come on and flash to indicate that the parking brake
is applied. You must be sure that the parking brake is
fully applied before leaving the vehicle.
Be sure the parking brake is firmly set when parked and
the gear shift lever is in the PARK position. When
parking on a hill you should apply the parking brake
before placing the gear shift lever in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the selector out of PARK.
