Hazard Warning Flashers
Your hazard warning ashers let you warn others. They
also let police know you have a problem. Your front
and rear turn signal lamps will ash on and off.
The hazard warning
asher button is located in
the center of the
instrument panel.
Your hazard warning ashers work no matter what
position your key is in, and even if the key is not in.
Press the button to make the front and rear turn signal
lamps ash on and off. Press the button again to
turn the ashers off.
When the hazard warning ashers are on, your turn
signals will not work.
Other Warning Devices

the side of the road about 300 feet (100 m) behind
your vehicle.
Horn
To sound the horn, press the horn symbol on the
steering wheel pad.
Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. If you have the tilt steering wheel, you
can raise it to the highest level to allow more room
for the driver to enter and exit the vehicle.

Turn and Lane-Change Signals
The turn signal has one upward (for right) and
one downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is nished, the lever will automatically
return to the off position.
To signal a lane change, raise or lower the lever until
the arrow starts to ash. Hold it there until the change is
completed. The lever will return by itself when released.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
As you signal a turn or a lane change, if the arrows
ash more quickly than normal, a signal bulb may
be burned out and other drivers will not see your
vehicle’s turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when signaling
a turn, check for a burned-out bulb or a blown fuse.
For bulb replacement, seeTaillamps, Turn Signal,
Stoplamps and Back-up Lamps on page 5-50. For a
blown fuse or circuit breaker, seeFuses and Circuit
Breakers on page 5-96.
Turn Signal On Chime
If a turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each ash of the turn
signal and the message TURN SIGNAL will also appear
in the DIC. To turn the chime and message off, move
the turn signal lever to the off position.
See “TURN SIGNAL” underDIC Warnings and
Messages on page 3-44DIC Warnings and Messages
for more information.
Headlamp High/Low-Beam Changer

the instrument panel
cluster will also be on.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they are working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly — and even dangerous. So please get to know
your warning lights and gages. They are a big help.
Your vehicle has a DIC that works along with the
warning lights and gages. SeeDriver Information
Center (DIC) on page 3-41for more information.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven, in either miles or kilometers.
The odometer mileage can be checked with the ignition
off. Simply press the trip information stem. See
“Odometer” underDIC Controls and Displays on
page 3-41for more information.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to
the mileage total of the old odometer, then it must
be. But if it cannot, then it is set at zero, and a label
must be put on the driver’s door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
Your vehicle has a trip odometer that can tell you how
far your vehicle has been driven since you last set
the trip odometer to zero.
See “Trip Odometer” underDIC Controls and Displays
on page 3-41for more information.
Tachometer
The tachometer displays
the engine speed in
revolutions per
minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.

Battery Warning Light
This light will come on
briey when you start the
vehicle, as a check to
show you it is working;
then it should go out.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
Have it checked right away. Driving while this light is
on could drain your battery and result in a vehicle that
may stall. SeeDIC Warnings and Messages on
page 3-44for more information.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and climate control system.
Up-Shift Light (Manual
Transmission)
This light appears when
you need to shift to the
next higher gear on
a manual transmission
vehicle.
Shifting when the indicator light is on will help you get
the best fuel economy. See “Up-Shift Light” under
Manual Transmission Operation on page 2-21for more
information.
3-31

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to ON. If it does not come on then, have
it xed so it will be ready to warn you if there is
a problem.When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
SeeParking Brake on page 2-27for more information.
The light will stay on if your parking brake does not
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push, or the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-57.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed
for service. United StatesCanada

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, this light will come
on briey when you
start your engine to show it
is working. Then it will
turn off. This is normal.
If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake
system warning light isn’t on, you still have brakes, but
you don’t have anti-lock brakes. If the regular brake
system warning light is also on, you don’t have anti-lock
brakes and there’s a problem with your regular
brakes. SeeBrake System Warning Light on page 3-32.
The anti-lock brake system warning light should come
on briey when you turn the ignition key to ON. If
the light doesn’t come on then, have it xed so it will be
ready to warn you if there is a problem.
Traction Off Light
If you have the traction
control system, this light
will come on when
the traction control system
has been turned off.
This light will come on briey when the ignition is turned
to ON, if it does not the system may require service.
For more information on the traction off light, see
Traction Control System (TCS) on page 4-9.
StabiliTrak®Not Ready Light
If you have the StabiliTrak®
system, this light will come
on when the StabiliTrak®
system has been
turned off.
This light will come on briey when the ignition is turned
to ON, if it does not the system may require service.
For more information, seeStabiliTrak
®System
(Automatic Transmission) on page 4-11.

Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.This light tells you if there
could be a problem with
your engine oil pressure.
The light goes on when you turn your key to ON or
START. It goes off once you start your engine. That’s a
check to be sure the light works. If it doesn’t come
on, be sure to have it xed so it will be there to warn
you if something goes wrong.
When the light comes on and stays on, it means that oil
isn’t owing through your engine properly. You could
be low on oil and you might have some other system
problem. SeeEngine Oil on page 5-13and “OIL” under
DIC Warnings and Messages on page 3-44for more
information.

Fuel Gage
When the ignition is on, the fuel gage tells you about
how much fuel you have remaining in the fuel tank.Here are three things that some owners ask about.
None of these indicate a problem with your fuel gage:
At the gas station, the gas pump shuts off before
the gage reads full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to
ll the tank.
The gage moves a little when you turn a corner or
speed up.
When the fuel in the fuel tank is low, you will see a
LOW FUEL message on the Driver Information
Center (DIC) display. SeeDIC Warnings and Messages
on page 3-44for more information. United States
