Audio System(s)
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.
If that equipment is replaced or additional equipment
is added to your vehicle, the chimes may not work.
Make sure that replacement or additional equipment
is compatible with your vehicle before installing it.
SeeAccessories and Modifications on page 5-3.
The vehicle has Retained Accessory Power (RAP).
With RAP, the audio system can be played even after
the ignition is turned off. SeeRetained Accessory
Power (RAP) on page 2-25for more information.

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 1-13.
{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.

Braking
SeeBrake System Warning Light on page 3-33.
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.
If the vehicle has Electronic Stability Control (ESC) and
the 2.0L turbocharged engine, it also has a hydraulic
brake boost feature which supplements the power brake
system to maintain consistent brake performance under
conditions of low brake booster vacuum. Low brake
booster vacuum conditions can include initial start up
after the vehicle has been parked for several hours, very
frequent brake stops, or high altitude driving. When
hydraulic brake boost is active, minor brake pulsation or
movement might be felt but this is normal. If brake pedal
feel changes or the brake pedal feels hard to push, the
system might not be receiving the intended brake boost
and the SVC BRAKE SYSTEM DIC message may be
displayed.
4-4

Under certain weather or operating conditions, occasional
brake squeak, squeal, or other noise might be heard with
the vehicle’s performance braking system. The brake
system on SS models is designed for superior fade
resistance and consistent operation using high
performance brake pads. Brake noise and brake dust
are normal and do not affect system performance.
Adding non-dealer/non-retailer accessories can affect
vehicle performance. SeeAccessories and Modifications
on page 5-3.
Antilock Brake System (ABS)
The vehicle might have the Antilock Brake System
(ABS), an advanced electronic braking system that helps
prevent a braking skid.
If the vehicle has ABS,
this warning light on the
instrument panel comes on
briey when the vehicle is
started.When the engine is started, or when 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 or pulses a little. This is normal.
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.

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 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 ashes while the
traction control system is
limiting wheel spin.
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.
SeeElectronic Stability Control (ESC)/Traction Control
System (TCS) Indicator/Warning Light on page 3-35
for more information.If the vehicle is in cruise control while TCS begins
to limit wheel spin, the cruise control will automatically
disengage. The cruise control can be re-engaged when
road conditions allow. SeeTurn 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 3-50for more information.
The Traction Control System comes on automatically
whenever the vehicle is started. 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”
your vehicle to attempt to free it. It may also be necessary
to turn off the system when driving in off-road conditions
where high wheel spin is required. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 4-24.
4-10

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.
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 that 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 3-48.
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, thedifferential 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, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the drive
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not attempt
to shift when the drive wheels do not have traction.
Damage caused by misuse of the vehicle is not
covered. See the 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 while the system
activates, the ESC/TCS light ashes and the cruise
control automatically disengages. The cruise control can
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.
4-11

Enhanced Traction System (ETS)
The 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.
If the vehicle has ETS, there is not an ESC/TCS button
on the instrument panel. To turn the system off, shift
to L (Low) or R (Reverse). There is more information
about how to turn the system off later in this section.
The ETS indicator/warning light ashes and
LOW TRACTION appears on the Driver Information
Center (DIC) when the traction control system is actively
limiting wheel spin. The system may be heard or felt while
it is working, but this is normal. Slippery road conditions
may exist if this message is displayed, so adjust your
driving accordingly.
If the vehicle is in cruise control when the ETS begins
to limit wheel spin, the cruise control will automatically
disengage. The cruise control can be re-engaged when
road conditions allow. 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 the system is turned off by moving the shift lever
to L (Low), the indicator/warning light comes on
and stays on. To turn the system back on, move
the shift lever back to a position other than L (Low).
The indicator/warning light should go off.
The indicator/warning light will come on when the
parking brake is set with the engine running, and it
will stay on if the parking brake does not release fully.
If the transmission shift lever is in any position other
than L (Low) and the indicator/warning light stays on
after the parking brake is fully released, 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.

Steering
Electric Power Steering
If 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.
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 POWER STEERING message
comes on, contact your dealer/retailer for service
repairs. SeeDIC Warnings and Messages on page 3-50.
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.
