WARNING!
Driving a vehicle with the BRAKE warning light on
is dangerous. A significant decrease in braking per-
formance or vehicle stability during braking may
occur. It will take you longer to stop the vehicle or
will make your vehicle harder to control. You could
have an accident. Have the vehicle checked immedi-
ately.
The operation of the BRAKE warning light can be
checked by turning the ignition switch from the OFF
position to the ON position. The light should illuminate
for approximately two seconds. The light should then
turn off unless the parking brake is applied or a brake
fault is detected. If the light does not illuminate, have the
light inspected by an authorized dealer.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 Ð 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.
20. Security Alarm System Indicator Light Ð If
Equipped
This light will flash rapidly for approximately 16 seconds
after all of the doors are locked and closed to signal that

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-TracTOperating Information/Precautions Ð
If Equipped
The Selec-Tracttransfer 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 surfaceincluding 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.

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.
N
Neutral - Disengages both the front and rear driveshafts
from the powertrain. To be used for flat towing behind
another vehicle. Refer to ªRecreational Towingº in Sec-
tion 5 for more information.
4LO
Part Time 4±Wheel Drive Low Range - Low speed
4±wheel drive. Locks the transfer case inter-axle differ-
ential. Forces the front and rear wheels to rotate at the
same speed. Additional traction and maximum pulling
power for loose, slippery road surfaces only. Do not
exceed 25 mph (40 km/h).
