WARNING!
ABS (Anti-Lock Brake System) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevail-
ing road conditions. ABS cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents. The capabilities of an ABS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize
the user’s safety or the safety of others.
TCS (Traction Control System)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in the
“Partial Off” mode. Refer to “ESP (Electronic Stability
Program)” in this section.

Also, the light will come on when the parking brake is
applied with the ignition switch in the ON position.
NOTE: This light shows only that the parking brake is
applied. It does not show the degree of brake application.
If the parking brake is off and the light remains on, have
the brake system inspected as soon as possible.
19. Full Time Indicator Light — If Equipped This light alerts the driver that the vehicle is in
the FULL TIME four–wheel drive mode, and
employs the inter-axle differential which al-
lows the front and rear wheels to rotate at
different speeds. (See page 234 for more information.)
20. Sentry Key/Security Alarm Indicator Light — If
Equipped
Refer to “Sentry Key Immobilizer System” or “Vehicle
Security Alarm” in Section 2 of this manual for more
information. 21. Fuel Gage
When the ignition key is in the ON position, the pointer
will show the level of fuel remaining in the fuel tank. A
small arrow indicates the side of the vehicle where the
filler cap (gas cap) is located.
22. Low Fuel Warning Light
When the fuel level reaches approximately 2.3 U.S.
Gallons (8.7 Liters) this light will come on and
remain on until fuel is added. The “Low Fuel
Warning Light” may turn on and off again, especially
during and after hard braking, accelerations, or turns.
This occurs due to the shifting of the fuel in the tank.
Also, a single chime will sound.
23. Airbag Warning Light This indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned on. If the

NOTE:Shifting into or out of 4L is possible with the
vehicle completely stopped, however difficulty may oc-
cur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch
teeth alignment and shift completion to occur. The pre-
ferred method is with the vehicle rolling 2 to 3 mph (3 to
5 km/h). Avoid attempting to engage or disengage 4L
with the vehicle moving faster than 2 to 3 mph (3 to 5
km/h).
Selec-Trac \bOperating Information/Precautions —
If Equipped
The Selec-Trac transfer case provides 5 mode positions -
normal 2-wheel drive mode, part-time 4-wheel drive
high range, full-time 4-wheel drive high range, neutral,
and 4-wheel drive low range.
This transfer case is equipped with an inter-axle differ-
ential which allows driving the vehicle in the 4 FULL
TIME position at all times on any given road surface including dry hard surfaced roads. The 4 FULL TIME
mode allows the front and rear wheels to rotate at
different speeds which eliminates driveline binding and
component wear that is normally associated with driving
the vehicle in the 4 PART TIME position on dry hard
surfaced roads. This feature provides the safety, security,
and convenience of operating in 4–wheel drive at all
times regardless of road conditions.
When additional traction is required the 4 PART TIME
and 4LO positions can be used to lock the front and rear
driveshafts together through the transfer case inter-axle
differential and force the front and rear driveshafts to
rotate at the same speed. This is accomplished by simply
moving the shift lever to these positions. The 4 PART
TIME and 4LO positions are intended for loose, slippery
road surfaces only. Driving in the 4 PART TIME and 4LO
positions on dry hard surfaced roads may cause in-
creased tire wear and damage to driveline components.
238 STARTING AND OPERATING

Proper operation of 4-wheel drive vehicles depends on
tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
can cause damage to the transfer case.
WARNING!
•Because 4-wheel drive provides improved trac-
tion, there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than road con-
ditions permit.
•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 drive-
shafts from the powertrain and will allow the
vehicle to move regardless of the transmission
position. The parking brake should always be
applied when the driver is not in the vehicle.
Shift Positions
For additional information on the appropriate use of each
transfer case mode position see the information below:
2WD
Rear Wheel Drive High Range - Normal street and
highway driving. Dry hard surfaced roads.
4 PART TIME
Part Time 4–Wheel Drive High Range - Locks the transfer
case inter-axle differential. Forces the front and rear
wheels to rotate at the same speed. Additional traction
for loose, slippery road surfaces only.
4 FULL TIME
Full Time 4-Wheel Drive High Range - Employs an
inter-axle differential. This allows front and rear wheels
to rotate at different speeds, on all road surfaces.
