28. Front Fog Light Indicator — If EquippedThis indicator will illuminate when the front fog
lights are on.
29. Anti-Lock Brake (ABS) Light This light monitors the Anti-lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the anti-lock portion of the brake system is
not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of anti-lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer. 30. Transmission Temperature Warning Light
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.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.

WARNING!
If the Transmission Temperature Warning Light is
illuminated and you continue operating the vehicle,
in some circumstances you could cause the fluid to
boil over, come in contact with hot engine or exhaust
components and cause a fire.
For vehicles equipped with a premium cluster this warn-
ing light will display in the Electronic Vehicle Informa-
tion Center (EVIC). Refer to ”Electronic Vehicle Informa-
tion Center (EVIC) — If Equipped” for further
information.
31. Seat Belt Reminder Light When the ignition switch is first turned to ON/
RUN, this light will turn on for four to eight
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’s seat belt remains unbuckled, the seat belt reminder light will
flash or remain on continuously. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” for further information.
32. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned to ON/RUN and remain on
briefly as a bulb check. If the light stays on or comes on
while driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If
the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.

transmission will automatically shift from third gear to
OVERDRIVE if the following conditions are present:
•the shift lever is in DRIVE
•the engine coolant has reached normal operating tem-
perature
•vehicle speed is above approximately 30 mph
(48 km/h)
•the TOW/HAUL switch has not been activated
•the transmission has reached normal operating
temperature
NOTE: If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into OVER-
DRIVE 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. 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 “Transmission
Temperature Warning Light” may illuminate and the
transmission may downshift out of OVERDRIVE until
the transmission cools down. After the transmission cools
down, the transmission will resume normal operation.
The transmission will downshift from OVERDRIVE to
DRIVE if the accelerator pedal is fully pressed 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 switch. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When

Overdrive Operation
The Overdrive automatic transmission contains an elec-
tronically controlled fourth and fifth gear (Overdrive).
The transmission will automatically shift from DRIVE to
Overdrive if the following conditions are present:
•the shift lever is in DRIVE;
•the engine coolant (antifreeze) has reached normal
operating temperature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the TOW/HAUL switch has not been activated;
•transmission has reached normal operating
temperature.
NOTE: If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive

NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant (antifreeze) are
warm [usually after 1 to 3 miles (1.6 to 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 switch
when the transmission is sufficiently warm will dem-
onstrate that the transmission is able to shift into and
out of Overdrive.
•If the vehicle has not been driven in several days, the
first few seconds of operation after shifting the trans-
mission 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
cause damage to the transmission. The torque con-
verter will refill within five seconds after starting the
engine.
FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
Four-wheel drive trucks are equipped with either a
manually shifted transfer case or an electronically shifted
transfer case. Refer to the operating instructions for your
transfer case, located in this section for further informa-
tion.
Manually Shifted Transfer Case – If Equipped
The transfer case provides four mode positions.
•Two-wheel drive high range (2H)
•Four-wheel drive high range (4H)
•Neutral (N)
•Four-wheel drive low range (4L)
This transfer case is intended to be driven in the 2H
position for normal street and highway conditions such
as dry, hard surfaced roads.

your vehicle’s abilities and be able to recover it if
something goes wrong. You should never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls do not
attempt to restart it. Determine if it has ingested water
first. The key to any crossing is low and slow. You want
to use first gear in 4L (Low Range) and proceed very
slowly with a constant slow speed (3-5 mph [5–8 km/h]
maximum) and light throttle. Keep the vehicle moving;
do not try to accelerate through the crossing. After
crossing any water higher than the bottom of the axle
differentials, you should inspect all of the vehicle fluids
for signs of water ingestion.CAUTION!
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you drive
too fast or through too deep of water. Water can cause
permanent damage to engine, driveline or other
vehicle components and your brakes will be less
effective once wet and/or muddy
•Before You Cross Any Type Of Water– As you
approach any type of water you need to determine if
you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a
stick. You need to be sure of its depth, approach angle,
current and bottom condition. Be careful of murky or
muddy waters, check for hidden obstacles. Make sure
you will not be intruding on any wildlife and you can
recover the vehicle if necessary. The key to a safe5

CAUTION! (Continued)
•Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission, axle, etc.) for signs of contamination
(i.e., fluid that is milky or foamy in appearance)
after driving through standing water. Do not con-
tinue to operate the vehicle if any fluid appears
contaminated, as this may result in further dam-
age. Such damage is not covered by the New
Vehicle Limited Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
