CONTROL TRAC-AUTOMATIC
FOUR-WHEEL DRIVE SYSTEM
(IF EQUIPPED)
Your 4x4 features a heavy-duty
Control Trac system, includes a
computer-operated transfer case.
Coupled with a
center-disconnected front axle, this
unique system is interactive with
the road, continually monitoring
and adjusting torque delivery to
the front and rear wheels to
optimize vehicle control.
Positions of the Control Trac
system
The Control Trac A4WD system
functions in four modes:
²2Hposition delivers power only
to the rear axle.
²A4WDposition delivers power
to the rear axle, and the front
axle when road conditions
dictate the need for increased
traction.
²4Hposition provides
mechanically locked four-wheel
drive power delivery to front
and rear axles.
²4Lposition provides
mechanically locked four-wheel
drive when above average power
at reduced speeds is required.

Utility and four-wheel
drive vehicles arenot
designed for cornering at speeds
as high as passenger cars any
more than low-slung sports cars
are designed to perform
satisfactorily under off-road
conditions. Avoid sharp turns or
abrupt maneuvers in these
vehicles.
Using the Control Trac system
Shifting to A4WD
Move the 4WD control to A4WD at
a stop or at speeds up to 88 km/h
(55 mph).
²At temperatures below 0É C
(32É F), shifts from 2H to A4WD
or 4H should not be performed
above 72 km/h (45 mph).
²Do not shift into A4WD when
only the rear wheels are
spinning.
Shifting to 2H
Move the 4WD control to 2H at
any forward speed.

Driving off-road with 4WD
Your vehicle is specially equipped
for driving on snow, sand, mud or
other rough terrain and has
operating characteristics that differ
from those of other conventional
vehicles.
When using 4WD, maintain
steering wheel control at all times,
especially in rough terrain. Since
sudden changes in terrain can
result in abrupt steering motion,
always grip the steering wheel
from the outside. Do not grip the
spokes.
Drive cautiously to avoid vehicle
damage from road debris such as
rocks or stumps. Be sure to map
out your route before driving in
any off road area.
For more information on driving
off-road and proper operation of
your 4WD vehicle, refer theFour
Wheelingsupplement in your
Owner's Portfolio.

with all of the vehicle wheels on
the ground.
Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of the vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of control and
personal injury.
Preparing to tow
Use the proper equipment for
towing a trailer and make sure that
it is properly attached to your
vehicle. See your dealer or a
reliable trailer retailer if you
require assistance.
If your vehicle is not equipped
with the factory heavy duty trailer
tow option, auxiliary coolers are
recommended for the automatic
transmission system if you are
planning on:
²traveling farther than 80 km (50
miles)
²towing in hilly terrain
²towing frequently
Calculating trailer loads
To determine the amount of weight
that your vehicle can carry:
²Obtain ratings from the Safety
Compliance Certification label
and the trailer towing
specifications in this chapter.
exd_preparing_tow
exd_calculating_load
Driving
129

should the vehicle weight ratings
per axle or combination truck and
trailer exceed the weight ratings
listed on the Safety Compliance
Certification label located on the
driver's side door.
When connecting a trailer hitch:
1. Turn off the air suspension
switch.
2. Connect the trailer.
3. Turn the air suspension back on.
Adjusting an equalizing
hitch so the rear bumper
of the vehicle is lower or higher
than it was unloaded will defeat
the function of the load
equalizing hitch and may cause
unpredictable handling.
Driving while towing a trailer
Speed control (if equipped) may
not work properly while towing on
long, steep grades.
Driving with an automatic
transmission:
²use D, 1 or 2 rather than
Dwhile towing up or down
steep hills
²anticipate stops and brake
gradually.
Towing behind another vehicle
Your vehicle can not be flat towed
with all wheels on the ground.
No neutral tow kit is available for
your vehicle.

²Turn off the ignition.
²Set the parking brake.
²Activate the hazard flashers.
Spare tire information

spare tire that may be used as a
spare or as a regular tire. The
spare is identical to the other tires

Removing flat tire and installing
spare
6. Use the tip of the lug wrench to
remove any wheel trim. Insert the
tapered end of the lug wrench
behind the wheel covers or
hubcaps and twist off.
7. Loosen the wheel nuts with the
lug wrench. Do not remove the lug
nuts until the tire has been raised
off the ground.
8. Insert the jack handle into the
jack and use the handle to slide
the jack under the vehicle.
9. Position the jack according to
the following guides and turn the
jack handle clockwise until the
wheel is completely off the ground.
²When one of the back wheels is
off the ground, the transmission
alone will not prevent the
vehicle from moving or slipping
off the jack, even if the vehicle
is in P (Park). To prevent the
vehicle from moving when you
change the tire, be sure that the
parking brake is set and the
diagonally opposite wheel is
blocked. If the vehicle slips off
the jack, someone could be
seriously injured.
