Four-Wheel Drive

Transfer Case Buttons
Your vehicle's transfer case buttons
allow you to shift into and out of the vari-
ous four-wheel drive modes.
The switches, located above the center
console, include:
S
4 (Four-Wheel High): Used for driv-
ing in most street and highway situa-
tions.
S
4 (Four-Wheel High Lock): Used
when extra traction is needed in most
off-road situations.
T
4 (Four-Wheel Low Lock): Used in
extreme off-road conditions.
When shifting between Four-Wheel High
and Four-Wheel High Lock, you must be
traveling less than 45 mph. To shift,
press the desired button. The indicator
light will flash while shifting. The light will
continue to flash if your speed is above
45 mph, indicating the shift has not
occurred. The light will remain lit when
the shift is complete. Neutral is used
only when towing the vehicle.
Note: Shifting the transfer case to
Neutral can cause the vehicle to roll
even if the transmission is in Park. Be
sure to set the parking brake before
placing the transfer case in Neutral.
Locking Rear Axle
The locking rear axle can provide addi-
tional rear wheel traction when driving in
off-road conditions such as climbing
over large rocks or up steep grades.
This feature can be engaged only when
the transfer case is in the 4LO Lock
mode by pressing the
the center console. The vehicle should
be stopped when locking the rear axle.
The locking rear axle will be disengaged
when traveling above 20 mph.
See Section 4 of your Owner Manual.

Off-Road Driving Basics

Off-road driving can be great fun, but it
does have its hazards. The greatest
hazard can be the terrain itself. Off-road
driving involves some new skills, so it's
very important to read this guide as well
as your Owner Manual.
Loading Your Vehicle for Off-Road
Driving
There are some important things to
remember about loading your vehicle:
• The heaviest items should be on the
load floor and forward of the rear
axle. Put heavier items as forward as
possible, but do not place them in the
front seat area.
• Be sure the load is secured properly
to prevent items from moving during
off-road driving.
Note:
• Cargo on the load floor piled higher
than the seat can be thrown forward
during sudden stops.
• Unsecured cargo on the load floor
can be tossed about when driving
over rough terrain.
• Heavy loads on the roof raise the
vehicle's center of gravity, making it
more likely to roll over.
