28. Transmission Oil Temperature Warning Light
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. If this
light comes on, stop the vehicle and run the
engine at idle or faster, with the transmission in NEU-
TRAL until the light goes off.
ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the time in hours and
minutes whenever the ignition switch is in the “ON” or
“ACC” position.
When the ignition switch is in the “OFF” position, or
when the radio frequency is being displayed, time keep-
ing is accurately maintained.
Clock Setting Procedure
1. Turn the ignition switch to the “ON” or “ACC”
position. Using the point of a ballpoint pen or similar
object, press either the “H” (Hour) or “M” (Minute)
buttons on the radio. The display will show the time.
2. Press the “H” button to set hours or the “M” button to
set minutes. The time setting will increase each time you
press a button.

speeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation isencountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.
NOTE:On models equipped with Diesel engines, the
idle speed will automatically increase to 1000 rpm at
elevated coolant temperatures to improve engine cooling.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.

NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer also to the Note under
torque converter clutch, later in this section.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough the TRANS TEMP light
may illuminate and the transmission may downshift out
of Overdrive until the transmission cools down. After
cooldown, the transmission will resume normal opera-
tion.
The transmission will downshift from Overdrive to Drive
if the accelerator pedal is fully depressed at vehicle
speeds above approximately 35 mph (56 km/h).When To Use “TOW/HAUL” Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the “TOW/HAUL” button. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in “TOW/HAUL” mode, 5th gear (if
236 STARTING AND OPERATING

equipped) is disabled and 2-3 and 3-4 shift patterns are
modified. Shifts into Overdrive (4th gear) are allowed
during steady cruise (for improved fuel economy) and
automatic closed-throttle downshifts to 3rd gear (for
improved braking) will occur during steady braking.
The “TOW/HAUL” light will illuminate in the instru-
ment cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the “TOW/HAUL” mode is desired,
the button must be pressed each time the engine is
started.
Torque Converter Clutch
A feature, designed to improve fuel economy, has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation inhigh gear. When the vehicle speed drops or during
acceleration when the transmission downshifts to second
gear, the clutch automatically disengages.
NOTE:The torque converter clutch will not engage
until the transmission fluid and engine coolant are warm
[usually after 1-3 miles (1.6 - 4.8 km) of driving]. Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmission
is not shifting into Overdrive when cold. This is normal.
Pressing the “TOW/HAUL” button, when the transmis-
sion is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of overdrive.
NOTE:If the vehicle has not been driven in several
days, the first few seconds of operation after shifting the
transmission into gear may seem sluggish. This is due to
the fluid partially draining from the torque converter into
the transmission. This condition is normal and will not

Automatic Transmission Oil Temperature Warning
Light
All vehicles with automatic transmissions are equipped
with a transmission sump oil temperature sensor and
warning light. If elevated transmission temperatures are
encountered, the engine controller will select the most
desirable gear until the transmission temperatures are
reduced. If transmission oil temperatures continue to
rise, a warning light located in the instrument cluster will
illuminate. If this should occur, stop the vehicle, shift to
Neutral, and run the engine at idle or faster until the light
goes off.
Towing With An Automatic Transmission
Vehicles equipped with an automatic transmission may
shift into and out of Overdrive, or a lower gear, when
driving in hilly areas, when heavily loaded, or when
towing into heavy winds.
When this condition occurs, select TOW/HAUL mode or
shift into a lower gear to prevent excessive transmission
wear and/or overheating, and to provide better engine
braking.
NOTE:Do not exceed the following RPM while manu-
ally downshifting:
•5800 rpm with 3.7L engines.
•5800 rpm with 4.7L engines.
•5600 rpm with 5.7L engines.
If your vehicle has an automatic transmission and you
tow a trailer frequently, change transmission fluid and
filter(s) according to Maintenance Schedule “B.”
304 STARTING AND OPERATING

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.
•Operate 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.
•Do 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) according to Maintenance ScheduleB.
RECREATIONAL TOWING — 4 WHEEL DRIVE
VEHICLES (BEHIND MOTORHOME, ETC.)
Recreational Towing – 2 Wheel Drive Models
Recreational towing 2 Wheel Drive is not allowed.
Towing with the rear wheels on the ground can result in
severe transmission damage.
CAUTION!
Failure to follow these requirements can cause se-
vere damage to the transmission and/or transfer case.

4. Shift automatic transmission to N (NEUTRAL), or
depress the clutch on manual transmissions.
5. Shift transfer case lever to desired position.
6. Shift automatic transmission into P (Park).
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(NEUTRAL) position without first fully engaging
the parking brake. The transfer case N (NEUTRAL)
position disengages both the front and rear drive-
shafts from the powertrain and will allow the ve-
hicle to move regardless of the transmission posi-
tion. The parking brake should always be applied
when the driver is not in the vehicle.
CAUTION!
•Do not use a bumper mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
•Do not disconnect the rear driveshaft because
fluid will leak from the transfer case and damage
the internal parts.

NOTE:Flashing neutral (N) position indicator light
indicates that shift requirements have not been met.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging the
parking brake. The transfer case Neutral (N) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
despite the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
•Do not use a bumper mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
•Do not disconnect the rear driveshaft because
fluid will leak from the transfer case and fluid
loss will damage internal parts.
