To lock the rear axle, do the following:
1. Place the transfer case in the 4LO Lock mode. This
is the only mode which will allow the rear axle to
lock. SeeFull-Time Four-Wheel Drive on page 2-27
for more information regarding the transfer case
and 4LO Lock mode.
2. Press the button with the vehicle stopped or moving
less than 2 mph (3 km/h).
You must wait for the light in the button to stop ashing
and remain illuminated before the rear axle is locked.
Notice:If you try to lock the rear axle while your
vehicle is stuck and the tires are spinning, you
could damage your vehicle’s drivetrain. The repairs
would not be covered by your warranty. Always lock
the rear axle before attempting situations and/or
navigating terrain which could possibly cause the
vehicle to become stuck.
The locking rear axle will be disengaged when the
wheel speed is greater than 20 mph (32 km/h), if the
vehicle’s battery is low and/or the transfer case is
shifted out of 4LO Lock mode.
Notice:If you lock the rear axle while driving on
pavement, you could damage your vehicle’s
drivetrain. The repairs would not be covered by
your warranty. Do not use the locking rear axle
on pavement. If you need four-wheel drive when
traveling on pavement, use only 4HI.StabiliTrak®System
Your vehicle has a vehicle stability enhancement
system called StabiliTrak®. It is an advanced computer
controlled system that assists you with directional
control of the vehicle in difficult driving conditions.
StabiliTrak
®activates when the computer senses a
discrepancy between your intended path and the
direction the vehicle is actually traveling. StabiliTrak
®
selectively applies braking pressure at any one of
the vehicle’s brakes to assist the driver with keeping
the vehicle on the intended path.
When you rst start your vehicle and begin to drive
away, the system performs several diagnostic checks to
insure there are no problems. You may hear or feel
the system working. This is normal and does not mean
there is a problem with your vehicle.
If there is a problem detected with StabiliTrak
®,a
SERVICE STAB SYS message will be displayed on the
Driver Information Center (DIC). SeeDIC Warnings
and Messages on page 3-43for more information. When
this message is displayed, the system is not operational.
Adjust your driving accordingly.

Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer
but it will take much more effort.
Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned
on the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject
to the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when you
turn the front wheels. If there is no traction, inertia will
keep the vehicle going in the same direction. If you
have ever tried to steer a vehicle on wet ice, you will
understand this.
The traction you can get in a curve depends on the
condition of the tires and the road surface, the angle at
which the curve is banked, and your speed. While you
are in a curve, speed is the one factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to do their
work where the tires meet the road. Adding the sudden
acceleration can demand too much of those places.
You can lose control. SeeTraction Control System (TCS)
on page 4-5andStabiliTrak
®System on page 4-7.
What should you do if this ever happens? Ease up on
the accelerator pedal, steer the vehicle the way you
want it to go, and slow down.
