23. Water In Fuel Indicator—Diesel Only
Indicates there is water detected in the fuel
filter. Refer to the Maintenance section, Drain-
ing Fuel/Water Separator Filter, for water
drain procedure. (See page 410 for more infor-
mation.)
24. Low Washer Fluid Light
This light comes on when the washer fluid level falls
below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled.
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—Diesel Only
The Wait To Start Indicator will illuminate when
the ignition is turned to the run position and the
ambient temperature is below 66 degrees F. Follow
engine starting procedure for proper engine starting and
operating. Wait until the Wait To Start Indicator turns
OFF then start the vehicle.
27. 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.
28. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position. UNDERSTANDING YOUR INSTRUMENT PANEL 179

WARNING!Do not use the Tow/Haul feature when driving in icy
or slippery conditions as the increased engine brak-
ing can cause the rear wheels to slide and the vehicle
to swing around with the possible loss of vehicle
control, which may cause an accident possibly result-
ing in personal injury or death.
When To Lock Out Overdrive
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent 6–5–6 or 5–4–5 transmis-
sion shifting occurs, press the “TOW/HAUL” button.
This will improve performance and reduce the potential
for transmission overheating or failure due to excessive
shifting. 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 in
high gear. When the vehicle speed drops or during
acceleration when the transmission downshifts to 1st
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.278 STARTING AND OPERATING

4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel on single rear wheel (SRW)
models. On dual rear wheel models (DRW) the lug nuts
are a two piece assembly with a flat face. Lightly tighten
the nuts. To avoid risk of forcing the vehicle off the jack,
do not fully tighten the nuts until the vehicle has been
lowered. 6. Using the wheel wrench, finish tightening the nuts
using a crisscross pattern. Correct nut tightness is 135 ft.
lbs. (183 N·m) torque for single rear wheel (SRW) models
and 145 ft. lbs. (197 N·m) for dual rear wheel models. If in
doubt about the correct tightness, have them checked
with a torque wrench by your dealer or at a service
station.
WARNING!A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle.
Always stow the jack parts and the extra tire and
wheel in the places provided.376 WHAT TO DO IN EMERGENCIES

1. Tighten the wheel nuts in the numbered sequence to a
snug fit.
2. Retighten the wheel nuts in the same sequence to the
torques listed in the table. Go through the sequence a
second time to verify that specific torque has been
achieved. Retighten to specifications at 100 miles (160
km) and after 500 miles (800 km).
It is recommended that wheel stud nuts be kept torqued
to specifications at all times. Torque wheel stud nuts to
specifications at each lubrication interval.
Wheel Nuts
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the
bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles
of operation to allow the wheel nuts to become properly
set. All nuts should first be firmly seated against the380 WHAT TO DO IN EMERGENCIES

wheel. The nuts should then be tightened to recom-
mended torque. Tighten the nuts to final torque in
increments. Progress around the bolt circle, tightening
the nut opposite to the nut just previously tightened until
final torque is achieved. Recommended torques are
shown in the following chart.

To Stow The Flat Or Spare (If equipped)
Refer to Upfitters Body Builders Guide for information
on stowing your spare tire (If equipped). HOISTING
A conventional floor jack may be used at the jacking
locations, refer to the graphics that show jacking loca-
tions. However, a floor jack or frame hoist must never be
used on any other parts or the underbody.
CAUTION!Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result. WHAT TO DO IN EMERGENCIES 381
