Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That is
normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you are driving, stop as soon
as possible and turn the ignition off. Then start
the engine again to reset the system. If the light still
stays on, or comes on again while you are driving, your
vehicle needs service. If the regular brake system
warning light is not on, you still have brakes, but you do
not have anti-lock brakes. If the regular brake system
warning light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
Brake System Warning Light on page 3-38. Also
see “Service ABS” underDIC Warnings and Messages
on page 3-58.
The anti-lock brake system warning light will come on
briefly when you turn the ignition key to ON. This is
normal. If the light does not come on then, have it fixed
so it will be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
This light should come on
briefly as you start the
engine. If the light does not
come on then, have it
fixed so it will be ready to
warn you if there is a
problem.
If it stays on, or comes on and the DIC shows a
SERVICE TRACTION SYSTEM message when you are
driving, there is a problem with your TCS system and
your vehicle needs service. When this light is on,
the system will not limit wheel spin. Adjust your driving
accordingly. If the driver turns off the Traction Control
System by pressing the button on the console, the TCS
system light will come on and the TRACTION SYSTEM
OFF message will show on the DIC.

Notice:Modications made to the engine,
transmission, exhaust, intake or fuel system of your
vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
•Light Flashing— A misfire condition has been
detected. A misfire increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
•Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
•Reducing vehicle speed.
•Avoiding hard accelerations.
•Avoiding steep uphill grades.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle.Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart
the engine. If the light remains on steady, see “If
the Light Is On Steady” following. If the light is still
flashing, follow the previous steps, and see your dealer
for service as soon as possible.

Elapsed Time
Press the TRIP button until ELAP. TIME is displayed,
such as ELAP. TIME 00:00:00.00.
When the ignition is in ON, the Driver Information
Center (DIC) can be used as a stopwatch. The display
can show hours, minutes, seconds and hundredths
of a second. The elapsed time indicator will record up to
99 hours, 59 minutes and 59 seconds, then it will
reset to zero and continue counting. (Hundredths are
shown up to 59 minutes, 59 seconds and
99 hundredths). The display appears as ELAP. TIME
00:00:00.00 in the elapsed time function.
You can start or stop the elapsed time by pressing
RESET. To reset the elapsed time to zero, stop the timer
by pressing RESET. Then press and hold RESET
until ELAP. TIME 00:00:00.00 appears in the DIC.
Average Speed
Press the TRIP button until the average speed is
displayed, such as:
•AVERAGE SPEED 62 MPH or
•AVERAGE SPEED 100 km/h
Press reset in this mode to start calculating the average
speed. Press and hold RESET to clear.
Engine Oil Life
Press the TRIP button until the engine oil life is
displayed, such as OIL LIFE REMAIN 89%.
This is an estimate of the engine oil’s remaining useful
life. It will show 100% when the system is reset after
an oil change. It will alert you to change your oil
on a schedule consistent with your driving conditions.
When the remaining oil life is low, the system will
alert you with the message CHANGE OIL SOON.
When the oil life is down to zero, you will receive the
message CHANGE OIL NOW.
Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed. It
can’t be reset accurately until the next oil change.
To reset the system, see “How to Reset the Change Oil
Soon Message” underEngine Oil on page 5-13.
Also, seeEngine Oil on page 5-13andScheduled
Maintenance on page 6-4.

DIC Warnings and Messages
The following messages and warnings may appear in
the DIC display. The DIC display area is located in
the instrument panel cluster below the speedometer and
tachometer, directly above the steering column. You
may receive more than one message at a time.
Messages will appear one behind the other. To
acknowledge a message and remove it from the display,
press RESET. You may scroll through the messages
that may have been sent at the same time. The
message center is continuously updated with the vehicle
performance status.
ABS ACTIVE (Anti-Lock Brake System
Active):When your anti-lock system is adjusting brake
pressure to help avoid a braking skid, the ABS
ACTIVE message will be displayed.
Slippery road conditions may exist if this message is
displayed, so adjust your driving accordingly. The
message will stay on for a few seconds after the system
stops adjusting brake pressure.ACT HNDLG – WARMING UP:When you first start
your vehicle (especially during cold winter weather), and
begin to drive away (up to 6 mph (10 km/h)), the
message ACT HNDLG – WARMING UP may be
displayed in the DIC, the instrument panel cluster light
will be on, and a chime will sound. This is normal.
You can acknowledge this message by pressing the
RESET button. The Active Handling System
performance is affected until the next message WARM
UP COMPLETE is displayed in the DIC.
During hot or cold temperature conditions, this message
may be displayed in the DIC after exceeding 12 mph
(20 km/h) for 30 seconds. The Active Handling System is
off until the WARM UP COMPLETE message is
displayed.
ACTIVE HANDLING:Your vehicle is equipped with a
computer controlled system to assist the driver in
controlling the vehicle in difficult driving conditions. You
may feel or hear the system working and see the
ACTIVE HANDLING message displayed in the DIC.
This is normal when the system is operating. Also see
Braking on page 4-6.

LOW OIL LEVEL:Press RESET to acknowledge that
you have read the message and to remove it from
the display. The message will reappear every
10 minutes until this condition changes. Once the
vehicle senses a temperature change in the engine oil,
the light will remain off.
You will hear two chimes when this message is
displayed. If this message appears after starting your
engine, your engine oil level may be too low. You
may need to add oil. SeeEngine Overheating on
page 5-26.
LOW OIL PRESSURE:You will hear four chimes and
the CHECK GAGES telltale will come on when this
message is displayed. To acknowledge the warning,
press the RESET button. After you press the RESET
button, a message will be displayed and you will hear a
chime every minute until the vehicle is serviced. If
you do not press RESET, the message will remain on
the digital display until the vehicle is serviced.
Low oil pressure may be the result of a combination of
low oil level and abrupt changes in the vehicle’s
direction. When this warning is displayed, you should
not operate the engine at high rpm or make fast abrupt
moves. As soon as possible, you should check the
oil level. SeeEngine Oil on page 5-13.LOW TIRE PRESSURE (Except Z06):You will hear
two chimes when this message is displayed. To
acknowledge the warning, press RESET. After you
press RESET, a message will appear every 10 minutes
until this condition changes. This message indicates
that the pressure in one of your tires is less than 25 psi
(172 kPa). Next to the LOW TIRE PRESSURE
message, you can see either LF (left front), LR (left
rear), RF (right front) or RR (right rear) to indicate to you
which tire is low on pressure. You can receive more
than one tire pressure message at a time. To read other
messages that may have been sent at the same time,
press RESET. If a tire pressure message appears on the
DIC, stop as soon as you can. Have the tire pressures

Playing a CD
Insert a CD partway into the slot, label side up. The
player will pull it in. The CD should begin playing. CD
and the CD symbol will appear on the display. If
you want to insert a CD with the ignition off, first press
the EJECT or the RECALL button.
If you turn off the ignition or radio with a CD in the
player, it will stay in the player. When you turn on the
ignition or radio, the CD will start playing where it
stopped, if it was the last selected audio source.
As each new track starts to play the track number will
appear on the display.
The CD player can play the smaller 8 cm single CDs
with an adapter ring. Full-size CDs and the smaller CDs
are loaded in the same manner.
If playing a CD-R the sound quality may be reduced
due to CD-R quality, the method of recording, the quality
of the music that has been recorded, and the way the
CD-R has been handled. You may experience an
increase in skipping, difficulty in finding tracks, and/or
difficulty in loading and ejecting. If these problems occur
try a known good CD.Do not add paper labels to CDs, they could get caught
in the CD player.
Do not play 3 inch CDs without a standard adapter CD.
If an error appears on the display, see “CD Messages”
later in this section.

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. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.Anti-lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-39.

•Do not get too close to the vehicle you want to
pass while you are awaiting an opportunity. For one
thing, following too closely reduces your area of
vision, especially if you are following a larger
vehicle. Also, you will not have adequate space if
the vehicle ahead suddenly slows or stops.
Keep back a reasonable distance.
•When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and
do not get too close. Time your move so you will be
increasing speed as the time comes to move into
the other lane. If the way is clear to pass, you
will have a “running start” that more than makes up
for the distance you would lose by dropping
back. And if something happens to cause you to
cancel your pass, you need only slow down
and drop back again and wait for another
opportunity.
•If other vehicles are lined up to pass a slow vehicle,
wait your turn. But take care that someone is not
trying to pass you as you pull out to pass the slow
vehicle. Remember to glance over your shoulder
and check the blind spot.
•Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far
enough ahead of the passed vehicle to see its front
in your inside mirror, activate your right lane
change signal and move back into the right lane.
(Remember that your right outside mirror is convex.
The vehicle you just passed may seem to be
farther away from you than it really is.)
•Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.
•Do not overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it
may be slowing down or starting to turn.
•If you are being passed, make it easy for the
following driver to get ahead of you. Perhaps
you can ease a little 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 your vehicle’s
three control systems. In the braking skid, your 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.
A cornering skid is best handled by easing your foot off
the accelerator pedal.Remember: Any traction control system helps avoid only
the acceleration skid. If your TCS system is off, then
an acceleration skid is also best handled by easing your
foot off the accelerator pedal.
If your 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,
your 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,
you will want to 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 engine braking by shifting to a
lower gear). Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery
until your 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 anti-lock brake system (ABS) helps
avoid only the braking skid.
