Drunk Driving
{CAUTION
Drinking and then driving is
very dangerous. Your reexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious — or even
fatal — collision if you drive after
drinking. Do not drink and drive or
ride with a driver who has been
drinking. Ride home in a cab; or if
you are with a group, designate a
driver who will not drink.
Death and injury associated with
drinking and driving is a global
tragedy.
Alcohol affects four things that
anyone needs to drive a vehicle:
judgment, muscular coordination,
vision, and attentiveness.Police records show that
almost 40 percent of all motor
vehicle-related deaths involve
alcohol. In most cases, these deaths
are the result of someone who was
drinking and driving. In recent years,
more than 17,000 annual motor
vehicle-related deaths have been
associated with the use of alcohol,
with about 250,000 people injured.
For persons under 21, it is against
the law in every U.S. state to drink
alcohol. There are good medical,
psychological, and developmental
reasons for these laws.
The obvious way to eliminate the
leading highway safety problem
is for people never to drink alcohol
and then drive.
Medical research shows that alcohol
in a person’s system can make crash
injuries worse, especially injuries
to the brain, spinal cord, or heart.This means that when anyone who
has been drinking — driver or
passenger — is in a crash, that
person’s chance of being killed or
permanently disabled is higher than
if the person had not been drinking.
Control of a Vehicle
The following three systems
help to control the vehicle while
driving —brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of
the vehicle. SeeTraction Control
System (TCS) on page 4-8.
Adding non-dealer/non-retailer
accessories can affect vehicle
performance. SeeAccessories and
Modifications on page 5-3.

StabiliTrak®System
The vehicle has a vehicle stability
enhancement system called
StabiliTrak which combines antilock
brake, traction and stability control
systems and helps the driver
maintain directional control of the
vehicle in most 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 checks to 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.This light is located on the
instrument panel cluster.
It will ash when StabiliTrak is both
on and activated.
If the system fails to turn on or
activate, this light will be on solid.
When the light is on solid, the system
will not assist the driver maintain
directional control of the vehicle.
Adjust your driving accordingly.
The StabiliTrak system automatically
comes on 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.
StabiliTrak can be turned off if
needed.The Traction Control System
(TCS)/StabiliTrak button is located
on the instrument panel.
TCS can be turned off or turned
on by pressing and releasing the
TCS/StabiliTrak button. To disable
both StabiliTrak and TCS, press
and hold the button until the TCS/
StabiliTrak warning light turns on
solid.
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.
StabiliTrak may also turn off
automatically if it determines that a
problem exists with the system.

The TCS/StabiliTrak warning light
will be on solid to warn the driver that
StabiliTrak is disabled and requires
service. If the problem does not clear
itself after restarting the vehicle, see
your dealer/retailer for service.
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.
Trailer Sway Control (TSC)
The vehicle has a Trailer Sway
Control (TSC) feature as part of the
StabiliTrak system. If the vehicle is
towing a trailer and the system
detects that the trailer is swaying, the
vehicle’s brakes are applied without
the driver pressing the brake pedal.
The TCS/StabiliTrak warning light
will ash on the instrument panel
cluster to notify the driver to reduce
speed. If the trailer continues to
sway, StabiliTrak will reduce engine
torque to help slow the vehicle.Adding non-dealer/non-retailer
accessories can affect the vehicle’s
performance. SeeAccessories
and Modifications on page 5-3for
more information.
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel spin.
This is especially useful in slippery
road conditions. The system
operates only if it senses that any
of the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to
limit wheel spin and also reduces
engine power. The system may be
heard or felt while it is working, but
this is normal.This light will ash when TCS is
limiting wheel spin.
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. SeeRocking Your
Vehicle to Get It Out on page 4-27
andIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 4-27for
more information.
The TCS/StabiliTrak
®button is
located on the instrument panel.

ProCarManuals.com

Press and release this button to turn
off TCS. The TCS warning light will
be displayed on the instrument panel
cluster. The traction control system
can be turned back on by pressing
the TCS/StabiliTrak button.
If the system is limiting wheel spin
when the button is pressed, the
system will not turn off until there is
no longer a current need to limit
wheel spin. The system can
be turned back on at any time by
pressing the button again. If the TCS
light does not come on, TCS may
not be functioning properly and
the vehicle should be serviced at
your dealer/retailer.
Adding non-dealer/non-retailer
accessories can affect the vehicle’s
performance. SeeAccessories
and Modifications on page 5-3for
more information.All-Wheel Drive (AWD)
System
If the vehicle has all-wheel drive
(AWD), the AWD system operates
automatically without any action
required by the driver. If the front
drive wheels begin to slip, the rear
wheels will automatically begin to
drive the vehicle as required. There
may be a slight engagement noise
during hard use but this is normal.
This light is located on the
instrument panel cluster.
It will come on and stay on to
indicate there may be a problem
with the drive system and service is
required. If the light stays on, it must
be reset. To reset the light, turn the
ignition off and then back on again.
If the light stays on, see your
dealer/retailer for service.If the vehicle is exposed to extended
heavy AWD usage, the AWD system
will shut off to protect the system
from overheating. When the system
cools down, the AWD system will
activate again automatically; this
cool-down can take up to 20 minutes
depending on outside temperature
and vehicle use.
Steering
Electric Power Steering
If the vehicle has the electric power
steering system and the engine
stalls while driving, the power
steering assist system will continue
to operate until you are able to
stop the vehicle. If power steering
assist is lost because the electric
power steering system is not
functioning, the vehicle can be
steered but it will take more effort.
Driving Your Vehicle 4-9
ProCarManuals.com

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 electric 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.
Hydraulic Power Steering
If the vehicle has the hydraulic
power steering system and power
steering assist is lost because
the engine stops or the power
steering system is not functioning,
the vehicle can be steered but it
will take more effort.
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.
Steering in Emergencies
There are times when steering can
be more effective than braking. For
example, you come over a hill and
nd a truck stopped in your lane, or a
car suddenly pulls out from nowhere,
or a child darts out from between
parked cars and stops right in front of
you. These problems can be avoided
by braking — if you can stop in time.
But sometimes you cannot stop in
time because there is no room.
That is the time for evasive
action — steering around the
problem.
The vehicle can perform very well
in emergencies like these. First
apply the brakes. SeeBraking on
page 4-5. It is better to remove as
much speed as possible from a
collision. Then steer around the
problem, to the left or right
depending on the space available.

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 steeringor 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.
Remember: Any traction control
system helps avoid only the
acceleration skid. If the traction
control system is off, then an
acceleration skid is best handled by
easing your foot off the accelerator
pedal.
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 will be longer and
vehicle control more limited.
While driving on a surface with
reduced traction, try your best to
avoid sudden steering, acceleration,
or braking, including reducing vehicle
speed by shifting to a lower gear.
Any sudden changes could cause
the tires to slide. You may not realize
the surface is slippery until the
vehicle is skidding. Learn to
recognize warning clues — such as
enough water, ice, or packed snow
on the road to make a mirrored
surface — and slow down when
you have any doubt.
Remember: Any Antilock Brake
System (ABS) helps avoid only the
braking skid.

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.

Driving on Hills
Off-road driving often takes you up,
down, or across a hill. Driving safely
on hills requires good judgment and
an understanding of what the vehicle
can and cannot do. There are some
hills that simply cannot be driven, no
matter how well built the vehicle.
{CAUTION
Many hills are simply too steep for
any vehicle. If you drive up them,
you will stall. If you drive down
them, you cannot control your
speed. If you drive across them,
you will roll over. You could be
seriously injured or killed. If you
have any doubt about the
steepness, do not drive the hill.
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.

If you feel the vehicle starting to slide
sideways, turn downhill. This should
help straighten out the vehicle and
prevent the side slipping. The best
way to prevent this is to “walk the
course” rst, so you know what the
surface is like before driving it.
Stalling on an Incline
{CAUTION
Getting out on the downhill (low)
side of a vehicle stopped across
an incline is dangerous. If the
vehicle rolls over, you could be
crushed or killed. Always get out
on the uphill (high) side of the
vehicle and stay well clear of the
rollover path.
If the vehicle stalls when crossing
an incline, be sure you, and any
passengers, get out on the uphill
side, even if the door there is harder
to open. If you get out on the downhill
side and the vehicle starts to roll
over, you will be right in its path.If you have to walk down the slope,
stay out of the path the vehicle
will take if it does roll over.
Driving in Mud, Sand, Snow,
or Ice
When you drive in mud, snow, or
sand, the wheels do not get good
traction. Acceleration is not as quick,
turning is more difficult, and braking
distances are longer.
It is best to use a low gear when in
mud — the deeper the mud, the
lower the gear. In really deep mud,
keep the vehicle moving so it does
not get stuck.
When driving on sand, wheel
traction changes. On loosely packed
sand, such as on beaches or sand
dunes, the tires will tend to sink
into the sand. This affects steering,
accelerating, and braking. Drive at a
reduced speed and avoid sharp turns
or abrupt maneuvers.Hard packed snow and ice offer the
worst tire traction. On these surfaces,
it is very easy to lose control. On wet
ice, for example, the traction is so
poor that you will have difficulty
accelerating. And, if the vehicle does
get moving, poor steering and
difficult braking can cause it to slide
out of control.
{CAUTION
Driving on frozen lakes, ponds,
or rivers can be dangerous.
Underwater springs, currents
under the ice, or sudden thaws
can weaken the ice. Your vehicle
could fall through the ice and you
and your passengers could
drown. Drive your vehicle on
safe surfaces only.

Avoid staring directly into
approaching headlamps.
Keep the windshield and all glass
on your vehicle clean — inside
and out.
Keep your eyes moving,
especially during turns or curves.
No one can see as well at night as
in the daytime. But, as we get
older, these differences increase.
A 50-year-old driver might need
at least twice as much light to
see the same thing at night as
a 20-year-old.
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.
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.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
Allow extra following distance.
Pass with caution.
Keep windshield wiping
equipment in good shape.
Keep the windshield washer uid
reservoir lled.
Have good tires with proper tread
depth. SeeTires on page 5-43.
Turn off cruise control.
