Determine which radio the vehicle has and read the
following pages to become familiar with its features.
{CAUTION:
Taking your eyes off the road for extended periods
could cause a crash resulting in injury or death to
you or others. Do not give extended attention to
entertainment tasks while driving.
This system provides access to many audio and non
audio listings.
To minimize taking your eyes off the road while driving,
do the following while the vehicle is parked:
Become familiar with the operation and controls of
the audio system.
Set up the tone, speaker adjustments, and preset
radio stations.
For more information, seeDefensive Driving on
page 4-2.Notice:Contact your dealer/retailer before adding
any equipment.
Adding audio or communication equipment could
interfere with the operation of the vehicle’s engine,
radio, or other systems, and could damage them.
Follow federal rules covering mobile radio and
telephone equipment.
Notice:The chime signals related to safety belts,
parking brake, and other functions of your vehicle
operate through the radio/entertainment system.

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.
Combine several trips into a single trip.
Replace the vehicle’s tires with the same
TPC Spec number molded into the tire’s sidewall
near the size.
Follow recommended scheduled maintenance.
Defensive Driving
Defensive driving means “always expect the
unexpected.” The rst step in driving defensively is
to wear your safety belt — SeeSafety Belts: They Are
for Everyone on page 1-12.
{CAUTION:
Assume that other road users (pedestrians,
bicyclists, and other drivers) are going to be
careless and make mistakes. Anticipate what they
might do and be ready. In addition:
Allow enough following distance between you
and the driver in front of you.
Focus on the task of driving.
Driver distraction can cause collisions resulting in
injury or possible death. These simple defensive
driving techniques could save your life.
4-2

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 5-3.
Braking
SeeBrake System Warning Light on page 3-34.
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.
If the engine stops, 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 and the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can affect
vehicle performance. SeeAccessories and Modifications
on page 5-3.
4-4

Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that helps 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, and it might even be noticed that the brake pedal
moves a little. This is normal.
If there is a problem with
ABS, this warning light
stays on. SeeAntilock
Brake System (ABS)
Warning Light on
page 3-35.
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 antilock pump or
motor might be heard operating and the brake pedal
might be felt to pulsate, but this is normal.
4-5

Traction Control System (TCS)
The vehicle may have 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 the front wheels are spinning too much
or are beginning to lose traction. When this happens,
the system works the front brakes and reduces
engine power by closing the throttle and managing
engine spark to limit wheel spin.
This light will ash when
the traction control system
is limiting wheel spin.
The system may be heard or felt while it is working,
but this is normal.
If the vehicle is in cruise control when TCS begins to
limit wheel spin, the cruise control will automatically
disengage. The cruise control may be re-engaged when
road conditions allow. SeeCruise Control on page 3-10.When this light is on
solid and either the
SERVICE TRACTION or
TRACTION OFF message
is displayed, the system
will not limit wheel spin.
Adjust your driving accordingly. SeeDIC Warnings and
Messages on page 3-46for more information.
The Traction Control System is automatically enabled
whenever the vehicle is started. To limit wheel spin,
especially in slippery road conditions, always leave the
system enabled. TCS 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 4-19.
4-8

To turn the system off or
on, press and release this
button located on the
center console.
The DIC will display the appropriate message as
described previously when the button is pressed.
Traction Control Operation
Traction control limits wheel spin by reducing engine
power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when the vehicle is started, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses either of the front wheels are
spinning or beginning to lose traction while driving.
For more information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-43.
Notice:If the wheel(s) of one axle are allowed to
spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed,the differential could be damaged. The repairs would
not be covered by the vehicle warranty. Reduce
engine power and do not spin the wheel(s)
excessively while these lights and this message
are displayed.
Notice:When traction control is turned off, it is
possible to lose traction. If you attempt to shift with
the front wheels spinning with a loss of traction,
it is possible to cause damage to the transmission.
Do not attempt to shift when the front wheels do
not have traction. Damage caused by misuse of the
vehicle is not covered. See your warranty book
for additional information.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, a reduction
in acceleration may be noticed, or a noise or vibration
may be heard. This is normal.
If the vehicle is in cruise control when the system
activates, the ESC/TCS light will ash and the cruise
control will automatically disengage. The cruise control
may be re-engaged when road conditions allow.
SeeCruise Control on page 3-10.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
