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.
Adding non-dealer/non-retailer
accessories can affect vehicle
performance. SeeAccessories and
Modifications on page 9-3.
Braking
SeeBrake System Warning Light on
page 4-16.
Braking action involves perception
time and reaction time. Deciding
to push the brake pedal is
perception time. Actually doing it is
reaction time.
Average reaction time is about
three-fourths of a second. But that
is only an average. It might be
less with one driver and as long as
two or three seconds or more
with another. Age, physical
condition, alertness, coordination,
and eyesight all play a part. So
do alcohol, drugs, and frustration.
But even in three-fourths of a
second, a vehicle moving at 60 mph
(100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an
emergency, so keeping enough
space between the vehicle
and others is important.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 engine ever stops while the
vehicle is being driven, brake
normally but do not pump the brakes.
If the brakes are pumped, the
pedal could get harder to push down.

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.

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.
8-22 Driving and Operating
ProCarManuals.com

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 might 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.Driving at Night
Night driving is more dangerous than
day driving because some drivers
are likely to be impaired — by alcohol
or drugs, with night vision problems,
or by fatigue.
Night driving tips include:
Drive defensively.
Do not drink and drive.
Reduce headlamp glare by
adjusting the inside rearview
mirror.
Slow down and keep more space
between you and other vehicles
because headlamps can only
light up so much road ahead.
Watch for animals.
When tired, pull off the road.
Do not wear sunglasses.
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.

Blizzard Conditions
Being stuck in snow can be in a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program on page 12-6.
To get help and keep everyone
in the vehicle safe:
Turn on theHazard Warning
Flashers on page 4-4.
Tie a red cloth to an outside
mirror.
{CAUTION
Snow can trap engine exhaust
under the vehicle. This may cause
exhaust gases to get inside.
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
(Continued)
CAUTION (Continued)
If the vehicle is stuck in the snow:
Clear away snow from
around the base of your
vehicle, especially any that is
blocking the exhaust pipe.
Check again from time to
time to be sure snow does
not collect there.
Open a window about two
inches (5 cm) on the side of
the vehicle that is away from
the wind to bring in fresh air.
Fully open the air outlets on
or under the instrument
panel.
Adjust the Climate Control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control System in the
Index.
(Continued)
CAUTION (Continued)
For more information about
carbon monoxide, seeEngine
Exhaust on page 8-14.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (carbon
monoxide) gas to get inside.
CO could overcome you and kill
you. You cannot see it or smell it,
so you might not know it is in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust.
Run the engine for short periods
only as needed to keep warm,
but be careful.
To save fuel, run the engine for
only short periods as needed
to warm the vehicle and then shut
the engine off and close the window
most of the way to save heat.

Low-Prole Tires
If the vehicle has 225/40ZR18 or
215/45R18 size tires, they
are classied as low-prole
performance tires. These tires
are designed for very responsive
driving on wet or dry pavement.
You may also notice more
road noise with low-prole
performance tires and that they
tend to wear faster.
Notice:If the vehicle has
low-prole tires, they are more
susceptible to damage from
road hazards or curb impact
than standard prole tires.
Tire and/or wheel assembly
damage can occur when
coming into contact with road
hazards like, potholes, or
sharp edged objects, or when
sliding into a curb. The vehicle
warranty does not cover this
type of damage. Keep tires
set to the correct inationpressure and, when possible
avoid contact with curbs,
potholes, and other road
hazards.
Winter Tires
If the vehicle has 225/40ZR18 or
215/45R18 size tires, they are
classied as low-prole performance
tires. These tires are designed for
very responsive driving on wet or dry
pavement. If you expect to drive
on snow or ice covered roads often,
you may want to get winter tires
for your vehicle. All season tires
provide good overall performance on
most surfaces but they may not
offer the traction you would like or
the same level of performance
as winter tires on snow or ice
covered roads.
Winter tires, in general, are
designed for increased traction
on snow and ice covered roads.With winter tires, there may be
decreased dry road traction,
increased road noise, and shorter
tire tread life. After switching to
winter tires, be alert for changes in
vehicle handling and braking.
See your dealer/retailer for details
regarding winter tire availability
and proper tire selection. Also, see
Buying New Tires on page 9-54.
If you choose to use winter tires:
Use tires of the same brand and
tread type on all four wheel
positions.
Use only radial ply tires of the
same size, load range, and
speed rating as your original
equipment tires.
Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W,
Y and ZR speed rated tires.
If you choose winter tires with a
lower speed rating, never exceed
the tire’s maximum speed capability.

If the vehicle has P205/55R16 size
tires, additional air pressure is
required when driving the vehicle at
speeds of 99 mph (158 km/h) or
higher. Set the cold tire ination
pressure to the maximum ination
pressure shown on the tire sidewall,
or 32 psi (220 kPa), whichever is
lower. See the example following.
Example:
The maximum load and ination
pressure is molded on the tire’s
sidewall, in small letters, near the rim
ange. It reads something like this:
Maximum load 710 kg (1565 lbs)
350 kPa (51 psi) Max. Press.
For this example, the cold tire
ination pressure for high-speed
driving should be set at 32 psi
(220 kPa).
When high-speed driving ends,
return the tire pressure to the
recommended cold ination
pressure shown on the Tire and
Loading Information label.SeeLoading the Vehicle on
page 8-30. Tire pressure should be
checked and correctly set when
the tires are cold. SeeInflation - Tire
Pressure on page 9-47.
Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your vehicle’s tires
and transmit tire pressure readings to
a receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inated to
the ination pressure recommended
by the vehicle manufacturer on
the vehicle placard or tire ination
pressure label. (If your vehicle
has tires of a different size than the
size indicated on the vehicle
placard or tire ination pressure
label, you should determine the
proper tire ination pressure
for those tires.)As an added safety feature, your
vehicle has been equipped with
a tire pressure monitoring system
(TPMS) that illuminates a low
tire pressure telltale when one or
more of your tires is signicantly
under-inated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inate them to
the proper pressure. Driving on a
signicantly under-inated tire
causes the tire to overheat and can
lead to tire failure. Under-ination
also reduces fuel efficiency and
tire tread life, and may affect the
vehicle’s handling and stopping
ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if under-ination
has not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
