Audio System(s)
Determine which radio your vehicle has and then read the
pages following to familiarize yourself with its features.
{CAUTION:
This system provides you with far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and you
or others can be injured or killed. Always keep
your eyes on the road and your mind on the
drive — avoid engaging in extended searching
while driving.
Keeping your mind on the drive is important for
safe driving. SeeDefensive Driving on page 4-2.
Here are some ways in which you can help avoid
distraction while driving.While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering wheel
controls if the vehicle has them.
Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer/retailer. Also, check federal rules covering
mobile radio and telephone units. If sound
equipment can be added, it is very important to do
it properly. Added sound equipment may interfere
with the operation of your vehicle’s engine, radio,
or other systems, and even damage them.

Section 4 Driving Your Vehicle
4-1

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 your 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 your
vehicle. SeeTraction Control System (TCS) on page 4-6,
Enhanced Traction System (ETS) on page 4-9, and
Electronic Stability Control (ESC) on page 4-10.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.

Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have ABS, you can steer and brake at the same
time. However, if you do not have ABS, your rst
reaction — to hit the brake pedal hard and hold it
down — might be the wrong thing to do. Your wheels
can stop rolling. Once they do, the vehicle cannot
respond to your steering. Momentum will carry it in
whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the very
thing you were trying to avoid, or into traffic.
If you do not have ABS, use a “squeeze” braking
technique. This will give you maximum braking while
maintaining steering control. You can do this by pushing
on the brake pedal with steadily increasing pressure.
In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease off the brake pedal.
This will help you retain steering control. If you do have
ABS, it is different. SeeAntilock Brake System (ABS)
on page 4-5.
In many emergencies, steering can help you more than
even the very best braking.
Brake Assist
If your vehicle has ESC with ABS, it also has a brake
assist feature that responds to emergency braking
by generating additional pressure and engaging
the ABS. When this happens, the brake pedal will feel
easier to push. Just hold the brake pedal down rmly
and let the system work for you. You might feel the
brakes vibrate or notice some noise, but this is normal.
The brakes will return to normal operation after the brake
pedal is released.
Brake assist cannot compensate for unsafe driving
practices and braking effectiveness, itself, depends on
the condition of the road, tires, and brakes and
vehicle mass.
Traction Control System (TCS)
Your 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 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.
If your vehicle has TCS, there is a ESC/TCS button
located on the instrument panel.
4-6

This light ashes while the
traction control system is
limiting wheel spin.
You may feel or hear the system working, but this is
normal.
SeeElectronic Stability Control (ESC)/Traction Control
System (TCS) Indicator/Warning Light on page 3-33
for more information.
If your vehicle is in cruise control while TCS begins to
limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, the cruise control can be re-engaged. See
Turn Signal/Multifunction Lever on page 3-7.
When this light is on 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 3-43for more information.
The Traction Control System is automatically enabled
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should always
leave the system enabled. You can turn TCS off if you
ever need to.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn the
system off if your vehicle is stuck in sand, mud, ice or
snow, and you want to “rock” your 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 4-26.
To turn the system off or
on, press and release the
ESC/TCS button located
on the instrument panel.
The DIC displays the appropriate message as described
previously when the button is pressed.
4-7

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 you start your vehicle, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses that any of the wheels are spinning
or beginning to lose traction while driving. For more
information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-40.
Notice:If you allow the wheel(s) of one axle to spin
excessively while the ESC/TCS, ABS and Brake
warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed, you
could damage the differential. The repairs would not
be covered by your 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, or
Competitive Driving Mode is active, 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, you may notice
a reduction in acceleration, or may hear a noise or
vibration. This is normal.
If your vehicle is in cruise control while the system
activates, the ESC/TCS light ashes and the cruise
control automatically disengages. When road conditions
allow you to use cruise control again, you may
re-engage the cruise control. SeeCruise Control on
page 3-10.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
4-8

Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if
it senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may also
upshift the transmission to limit wheel spin. You may feel
or hear the system working, but this is normal.
If your vehicle has ETS, there is not an ESC/TCS
button on the instrument panel. To turn the system off,
shift to LOW (L) or REVERSE (R). There is more
information about how to turn the system off later in
this section.
The light below ashes and a LOW TRACTION
message will appear on the Driver Information Center
(DIC) when the traction control system is actively limiting
wheel spin. You may feel or hear the system working,
but this is normal. Slippery road conditions may
exist if this message is displayed, so adjust your driving
accordingly.
If your vehicle is in cruise control when the ETS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may re-engage the cruise control.
SeeCruise Control on page 3-10.The ETS indicator/warning light may come on for the
following reasons:
The indicator/warning light ashes while the traction
control system is limiting wheel spin.
If you turn the system off by moving the shift lever to
LOW (L), the indicator/warning light will come on and
stay on. To turn the system back on, move the shift
lever back to a position other than LOW (L). The
indicator/warning light should go off.
The indicator/warning light will come on when you set
your parking brake with the engine running, and it will
stay on if your parking brake does not release fully. If
the transmission shift lever is in any position other
than LOW (L) and the indicator/warning light stays on
after your parking brake is fully released, it means
there is a problem with the system.
If the traction control system is affected by an engine
related problem, the system will turn off and the
indicator/warning light will come on.
