Cruise Control
{CAUTION
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.With cruise control, a speed of
about 25 mph (40 km/h) or more can
be maintained without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 25 mph (40 km/h).
The cruise control buttons
are located on the turn
signal/multifunction lever on the
left side of the steering wheel.
9(On/Off):Press and hold the
button on the back end of the cruise
control lever, to turn the cruise
control system on or off. The CC on
or CC off message will appear on
the instrument panel cluster at
the odometer display to show that
the cruise control system is on or off.
A
J(Set/Accelerate):Press to set
a speed and to accelerate the speed.
B
W(Resume/Coast):Press to
resume a set speed and to decrease
the speed.

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.
StabiliTrak®System
The vehicle may have StabiliTrak
which combines antilock brake,
traction and stability control systems
and helps the driver maintain
directional control of the vehicle
in most driving conditions.
When the vehicle is rst started and
driven away, the system performs
several diagnostic checks to ensure
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. The system should initialize
before the vehicle reaches 20 mph
(32 km/h).The system monitors vehicle
movements, and helps the driver
maintain control of the vehicle in
most driving situations. When the
vehicle’s stability is affected the
engine output is reduced, and the
brakes are applied to individual
wheels.
This light on the instrument panel
cluster will come on briey when the
ignition is turned on.
StabiliTrak is automatically enabled
whenever the vehicle is started. To
assist the driver with vehicle
directional control, especially in
slippery road conditions, the system
should always be left on. The system
can be turned off if needed.It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle is
stuck in sand, mud, ice or snow, and
you want to “rock” the vehicle to
attempt to free it. It may also be
necessary to turn off the system
when driving in extreme off-road
conditions where high wheel spin is
required. SeeIf Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow on
page 8-29.
StabiliTrak may also turn off
automatically if it determines that a
problem exists with the system.
The light on the instrument panel
cluster will be on solid to warn
the driver that StabiliTrak is disabled
and requires service. If the problem
does not clear after restarting
the vehicle, see your dealer/retailer
for service.

Thegswitch is located on the
instrument panel below the Driver
Information Center (DIC).
To turn off StabiliTrak, press and
hold the
gswitch until the light in the
switch illuminates.
To turn StabiliTrak on again, press
the
gswitch again or restart the
vehicle.
A light in the switch should come on
briey when the ignition key is
turned to ON/RUN as a check that
the light is working.
Adding non-dealer/non-retailer
accessories can affect the vehicle’s
performance. SeeAccessories
and Modifications on page 9-3for
more information.
Steering
If the engine stalls while driving, the
power steering assist system
should continue to operate until you
are able to stop the vehicle. If
power steering assist is lost because
the power steering system is not
functioning, the vehicle can be
steered but it will take more effort.
If you turn the steering wheel in
either direction several times until it
stops, or hold the steering wheel
in the stopped position for an
extended amount of time, you may
notice a reduced amount of
power steering assist. The normal
amount of power steering assist
should return shortly after a
few normal steering movements.
The power steering system does not
require regular maintenance. If you
suspect steering system problems
and/or the Service Vehicle Soon light
comes on, contact your dealer/
retailer for service repairs.
Steering Tips
It is important to take curves at a
reasonable speed.
Traction in a curve depends on the
condition of the tires and the
road surface, the angle at which the
curve is banked, and vehicle
speed. While in a curve, speed is
the one factor that can be controlled.
If there is a need to reduce speed,
do it before entering the curve,
while the front wheels are straight.
Try to adjust the speed so you
can drive through the curve.
Maintain a reasonable, steady
speed. Wait to accelerate until out
of the curve, and then accelerate
gently into the straightaway.

Passing
Passing another vehicle on a
two-lane road can be dangerous.
To reduce the risk of danger
while passing:
Look down the road, to the sides,
and to crossroads for situations
that might affect a successful
pass. If in doubt, wait.
Watch for traffic signs, pavement
markings, and lines that could
indicate a turn or an intersection.
Never cross a solid or
double-solid line on your side of
the lane.
Do not get too close to the vehicle
you want to pass. Doing so can
reduce your visibility.
Wait your turn to pass a slow
vehicle.
When you are being passed, ease
to the right.
Loss of Control
Let us review what driving experts
say about what happens when
the three control systems — brakes,
steering, and acceleration — do
not have enough friction where the
tires meet the road to do what
the driver has asked.
In any emergency, do not give up.
Keep trying to steer and constantly
seek an escape route or area of
less danger.
Skidding
In a skid, a driver can lose control of
the vehicle. Defensive drivers avoid
most skids by taking reasonable care
suited to existing conditions, and by
not overdriving those conditions.
But skids are always possible.The three types of skids correspond
to the vehicle’s three control
systems. In the braking skid, the
wheels are not rolling. In the steering
or cornering skid, too much speed
or steering in a curve causes tires
to slip and lose cornering force.
And in the acceleration skid, too
much throttle causes the driving
wheels to spin.
If the vehicle starts to slide, ease
your foot off the accelerator pedal
and quickly steer the way you want
the vehicle to go. If you start steering
quickly enough, the vehicle may
straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
slow down and adjust your driving to
these conditions. It is important to
slow down on slippery surfaces
because stopping distance is longer
and vehicle control more limited.

Driving in Rain and on
Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or owing water.
{CAUTION
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
(Continued)
CAUTION (Continued)
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
owing water could cause your
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through owing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under your vehicle’s
tires so they actually ride on
the water. This can happen if the
road is wet enough and you
are going fast enough. When your
vehicle is hydroplaning, it has little or
no contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is
to slow down when the road is wet.

Top of hills: Be alert — something
could be in your lane (stalled car,
accident).
Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 32°F
(0°C) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.Drive with caution, whatever the
condition. Accelerate gently
so traction is not lost. Accelerating
too quickly causes the wheels
to spin and makes the surface under
the tires slick, so there is even
less traction.
Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
TheAntilock Brake System (ABS)
on page 8-18improves vehicle
stability during hard stops on
a slippery roads, but apply the
brakes sooner than when on
dry pavement.Allow greater following distance
on any slippery road and watch for
slippery spots. Icy patches can occur
on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid
sudden steering maneuvers and
braking while on ice.
Turn off cruise control, if equipped,
on slippery surfaces.
