Your Driving, the
Road, and the Vehicle
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
Avoid fast starts and accelerate
smoothly.
Brake gradually and avoid abrupt
stops.
Avoid idling the engine for long
periods of time.
When road and weather
conditions are appropriate, use
cruise control, if equipped.
Always follow posted speed limits
or drive more slowly when
conditions require.
Keep vehicle tires properly
inated.
Driving Your Vehicle 4-1

And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry, or
icy; tire tread; the condition of
the brakes; the weight of the vehicle;
and the amount of brake force
applied.
Avoid needless heavy
braking. Some people drive in
spurts — heavy acceleration
followed by heavy braking — rather
than keeping pace with traffic.
This is a mistake. The brakes might
not have time to cool between
hard stops. The brakes will wear out
much faster with a lot of heavy
braking. Keeping pace with
the traffic and allowing realistic
following distances eliminates a lot
of unnecessary braking. That
means better braking and longer
brake life.
If the vehicle ever loses electrical
power while it is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,the pedal could get harder to push
down. If the vehicle loses electrical
power, there will still be some
power brake assist but it will be
used when the brake is applied.
Once the power assist is used up, it
can take longer to stop, the brake
pedal will be harder to push,
and you might experience longer
pedal travel.
Adding non-dealer/non-retailer
accessories can affect vehicle
performance. SeeAccessories and
Modifications on page 5-3.
Hill Start Assist
This vehicle has a Hill Start Assist
(HSA) feature, which may be
useful when the vehicle is stopped
on a grade. This feature is
designed to prevent the vehicle from
rolling, either forward or rearward,
during vehicle drive off. After
the vehicle is stopped on an incline,
push the brake pedal completely
to the oor to activate Hill StartAssist. When the system activates,
a chime will sound and the HSA
ON message will be displayed.
Letting off the brake pedal slightly or
applying the accelerator pedal to
disengage Hill Start Assist gives the
driver two seconds to pull forward
or back up before the vehicle
starts to roll. Lightly ease off the
brake pedal to disengage Hill
Start Assist. The brakes will
automatically be held for a maximum
of two seconds while the driver
switches from applying the brakes
to pushing the accelerator pedal.
When Hill Start Assist is active, the
driver might experience a “hard
pedal.” This is normal and does not
affect safe brake operation.
On steeper hills, Hill Start Assist will
only activate if the driver tries to
move the vehicle up the hill. It will
not activate if the vehicle is in a
drive gear and facing downhill or if
the vehicle is facing uphill and
in R (Reverse).

Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that will
help prevent a braking skid.
When the engine is started and the
vehicle begins to drive away,
ABS checks itself. A momentary
motor or clicking noise might
be heard while this test is going on.
This is normal.
If there is a problem with ABS, this
warning light stays on. See
Antilock Brake System (ABS)
Warning Light on page 3-28.Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you. You
slam on the brakes and continue
braking. Here is what happens
with ABS:
A computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work
the brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the
obstacle while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls braking
pressure accordingly.Remember: ABS does not change
the time needed to get a foot
up to the brake pedal or always
decrease stopping distance. If you
get too close to the vehicle in
front of you, there will not be enough
time to apply the brakes if that
vehicle suddenly slows or stops.
Always leave enough room up
ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down rmly and
let antilock work. The brakes might
vibrate or some noise might be
heard, but this is normal.
Driving Your Vehicle 4-5

Braking in Emergencies
ABS allows the driver to steer
and brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Brake Assist
This vehicle has a Brake Assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied
the brake pedal in an attempt to
quickly stop or slow down the
vehicle. The stability system
hydraulic brake control module
increases brake pressure at each
corner of the vehicle until the
ABS activates. Minor brake pedal
pulsations or pedal movement
during this time is normal and the
driver should continue to applythe brake pedal as the driving
situation dictates The Brake Assist
feature will automatically disengage
when the brake pedal is released
or brake pedal pressure is quickly
decreased.
StabiliTrak®System
The vehicle has a vehicle stability
enhancement system called
StabiliTrak. It is an advanced
computer controlled system that
assists the driver with directional
control of the vehicle in difficult
driving conditions.
StabiliTrak activates when the
computer senses a discrepancy
between the 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 the vehicle is started and
begins to move, the system
performs several diagnostic checksto insure there are no problems.
The system may be heard or
felt while it is working. This is normal
and does not mean there is a
problem with the vehicle.
If cruise control is being used when
StabiliTrak activates, the cruise
control automatically disengages.
The cruise control can be
re-engaged when road conditions
allow. SeeCruise Control on
page 3-9.
If there is a problem detected with
StabiliTrak, a SERVICE STAB
SYS message displays on the Driver
Information Center (DIC). See
DIC Warnings and Messages on
page 3-37for more information.
When this message is displayed, the
system is not working. Adjust your
driving accordingly.
StabiliTrak comes on automatically
whenever the vehicle is started
and resets itself at each ignition
cycle. However, when the transfer
case is placed in Four-Wheel-Low
Lock mode, StabiliTrak is

Scanning the Terrain
Off-road driving can take you over
many different kinds of terrain.
Be familiar with the terrain and its
many different features.
Surface Conditions:Off-roading
surfaces can be hard-packed
dirt, gravel, rocks, grass, sand,
mud, snow, or ice. Each of these
surfaces affects the vehicle’s
steering, acceleration, and braking
in different ways. Depending on
the surface, slipping, sliding, wheel
spinning, delayed acceleration,
poor traction, and longer braking
distances can occur.
Surface Obstacles:Unseen or
hidden obstacles can be hazardous.
A rock, log, hole, rut, or bump
can startle you if you are not
prepared for them. Often these
obstacles are hidden by grass,
bushes, snow, or even the rise and
fall of the terrain itself.Some things to consider:Is the path ahead clear?
Will the surface texture change
abruptly up ahead?
Does the travel take you uphill or
downhill?
Will you have to stop suddenly or
change direction quickly?
When driving over obstacles or
rough terrain, keep a rm grip on the
steering wheel. Ruts, troughs, or
other surface features can jerk the
wheel out of your hands.
When driving over bumps, rocks, or
other obstacles, the wheels can
leave the ground. If this happens,
even with one or two wheels,
you cannot control the vehicle as
well or at all.
Because you will be on an unpaved
surface, it is especially important
to avoid sudden acceleration,
sudden turns, or sudden braking.Off-roading requires a different
kind of alertness from driving on
paved roads and highways. There
are no road signs, posted speed
limits, or signal lights. Use
good judgment about what is safe
and what is not.Crossing Obstacles
Approach Angle — a Key to
Mobility
If you encounter a large dip in the
terrain, do not enter straight on;
enter at an angle — 15° minimum
approach (A), 75° maximum
approach angle (B).
Driving Your Vehicle 4-19

Approaching a Hill
When you approach a hill, decide
if it is too steep to climb, descend, or
cross. Steepness can be hard to
judge. On a very small hill, for
example, there may be a smooth,
constant incline with only a
small change in elevation where
you can easily see all the way to the
top. On a large hill, the incline
may get steeper as you near the
top, but you might not see this
because the crest of the hill
is hidden by bushes, grass, or
shrubs.
Consider this as you approach
a hill:
Is there a constant incline, or
does the hill get sharply
steeper in places?
Is there good traction on the
hillside, or will the surface
cause tire slipping?
Is there a straight path up or
down the hill so you will not have
to make turning maneuvers?
Are there obstructions on the hill
that can block your path, such
as boulders, trees, logs, or ruts?
What is beyond the hill? Is there
a cliff, an embankment, a
drop-off, a fence? Get out and
walk the hill if you do not know. It
is the smart way to nd out.
Is the hill simply too rough?
Steep hills often have ruts,
gullies, troughs, and exposed
rocks because they are
more susceptible to the effects
of erosion.
See “Hill Start Assist” underBraking
on page 4-3for information on
vehicles stopped on a grade.
Driving Uphill
Once you decide it is safe to drive
up the hill:
Use transmission and transfer
case low gear and get a rm
grip on the steering wheel.
Get a smooth start up the hill
and try to maintain speed.
Not using more power than
needed can avoid spinning the
wheels or sliding.
Let the traction system work to
control any wheel slippage.
The traction control system
allows for moderate wheel spin
with some capability to dig in and
power up the hill.
