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 Cabtand
Mega Cabtmodels the rear of the floor console offers a
power outlet, and a tip out bin.
WARNING!
²This 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.
²In 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 endanger-
ing occupants of the vehicle. Items stored should
not exceed a total of 10 lbs (4.5 kg).
CAUTION!
²Many 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.
²Accessories 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.
²After 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.

INSTRUMENT CLUSTER DESCRIPTION
1. Check Gauges ± Premium Cluster Only
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gauges indicate a reading either too high or too low.
Examine the gauges carefully, and follow the instructions
contained below for each indicated problem.
NOTE:When the ignition switch is turned to OFF, the
Fuel Gauge, Voltmeter, Oil Pressure and Engine Coolant
Temperature gauges 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. 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 ªCheck Gaugesº indicator will illuminate
and a single chime will sound. The ªCheck Gaugesº
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.
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.

31. CRUISE Light
This indicator lights when the electronic speed control
system is turned on.
32. Coolant Temperature Light ± Base Cluster Only
This light indicates engine coolant temperature is
to high. If the light comes on, stop the vehicle, shift
into NEUTRAL, and increase the engine idle
speed for two to three minutes. If the light does not turn
off, shut your engine OFF and allow it to cool. See an
authorized dealer for service immediately. Refer to
ªCooling Systemº under ªMaintaining Your Vehicleº in
section 7.
CAUTION!
Do not leave your vehicle unattended with the en-
gine running as you would not be able to react to the
temperature indicator if the engine overheats.NOTE:Engine idle speed will automatically increase to
1000 rpm at elevated coolant temperatures to improve
engine cooling.
33. Battery Voltage Indicator Light ± Base Cluster
Only
When the engine is running, this light indicates
the electrical system voltage is out of normal
range. This 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.
34. Oil Pressure Indicator light ± Base Cluster Only
This light indicates continuous high or low oil
pressure, and under normal driving conditions,
may indicate a lubrication system malfunction. Immedi-
ate service should be obtained.

WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
If the vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster battery
or the battery in another vehicle. This type of start
can be dangerous if done improperly. Refer to ªJump
Startingº in Section 6.If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is
released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly.
If the engine shows no sign of starting after two 15-
second periods of cranking with the accelerator pedal
held to the floor, the normal starting procedure should be
repeated.
After Starting
The idle speed is automatically controlled and will de-
crease as the engine warms up.

information on towing a trailer with your vehicle. When
TSC is functioning, the ªESP/TCS Indicator Lightº will
flash, the engine power may be reduced and you may
feel the brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is disabled
when the ESP system is in the Partial Off or Full Off
modes.
TSC is only active in the default ªESP Onº mode. TSC can
be disabled by pressing the ESP Off button and entering
ªESP Partial Offº mode. It is not active in the ªESP Partial
Offº or ªESP Offº modes. Please refer to the ESP portion
of this section for an explanation of the different ESP
operating modes.WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
MULTI-DISPLACEMENT SYSTEM (MDS) Ð 5.7L
ENGINE ONLY
This feature offers improved fuel economy by shutting
off four of the engine's eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
338 STARTING AND OPERATING

NOTE:During snowplow usage on vehicles equipped
with an overhead console module, the outside tempera-
ture display will show higher temperatures than the
outside ambient temperature. The higher displayed tem-
perature is due to blocked or reduced airflow to the
underhood ambient temperature sensor by the snow-
plow. This is common, and outside temperature display
operation will return to normal when the snowplow is
removed.
General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer's instructions. Whenever the plow is
disconnected from the vehicle, coat the exposed angling
cylinder rods with chassis lubricant. The lift cylinder
should be extended upward and chassis lubricant ap-
plied to the lift rod. The hydraulic hoses interconnect to
keep the couplers clean.Keep all snowplow electrical connections and battery
terminals clean and free of corrosion.
When plowing snow, to avoid transmission and driv-
etrain damage, the following precautions should be ob-
served.
²Operate with transfer case in 4L when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4H.
²Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission between forward and reverse.
NOTE:Change the automatic transmission fluid and
filter(s), refer to ªMaintenance Scheduleº in Section 8.

HAZARD WARNING FLASHER
The Hazard Warning switch is mounted on the top of the
steering column as shown in the illustration.To engage the Hazard Warning lights, depress the button
on the top of the steering column. When the Hazard
Warning switch is activated, all directional turn signals
will flash off and on to warn oncoming traffic of an
emergency. Push the button a second time to turn off the
flashers.
This is an emergency warning system and should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning lights will continue to operate even
though the ignition switch is OFF.
NOTE:With extended use, the Hazard Warning lights
may discharge your battery.
