Clock (Hatchback Only)
Your vehicle has a digital clock. The clock is located
in the secondary instrument cluster on the center of the
instrument panel, above the center air outlets. When
the ignition is turned to ACC/ACCESSORY or ON/RUN,
the time is displayed in the digital clock. There are
two adjusting buttons for the digital clock:
H (Hour):To go forward one hour, press the H button
once. To go forward more than one hour, press and
hold the button until the correct hour is reached.
M (Minute):To go forward one minute, press the
M button once. To go forward more than one minute,
press and hold the button until the correct minute
is reached.
After disconnecting the battery or replacing the fuse,
reset the clock.
Safety Belt Reminders
Safety Belt Reminder Light
The safety belt light will
come on and stay on until
the driver’s safety belt
is buckled.
This light will come on briefly when you turn on the
ignition as a check to show you it is working.
3-44

Airbag Readiness Light
There is an airbag readiness light on the Secondary
Information Center (SIC), which shows the airbag
symbol. The system checks the airbag’s electrical system
for malfunctions. The light tells you if there is an electrical
problem. The system check includes the airbag sensor,
the airbag modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 1-56.
This light will come on
when you start your
vehicle, and it will flash for
a few seconds. Then the
light should go out. This
means the system is ready.
If the airbag readiness light stays on after you start the
vehicle or comes on or flashes when you are driving,
your airbag system may not work properly. Have
your vehicle serviced right away by your dealer/retailer.{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the airbag readiness light
stays on after you start your vehicle.
The airbag readiness light should flash for a few
seconds when you turn the ignition to ON/RUN.
If the light does not come on then, have it fixed so
it will be ready to warn you if there is a problem.
3-45

Passenger Airbag Status Indicator
(Hatchback)
Your vehicle has the passenger sensing system.
If you have a hatchback, the airbag off symbol will be
visible in the Secondary Information Center (SIC) during
the system check.
When you start the vehicle, the passenger airbag status
indicator will light for several seconds as a system check.
Then, after several more seconds, if the off symbol is lit
on the passenger airbag status indicator, it means that
the passenger sensing system has turned off the right
front passenger’s frontal airbag and seat-mounted side
impact airbag (if equipped).
{CAUTION:
If the off symbol in the passenger airbag
status indicator does not come on when you
have a rear-facing child restraint installed in
the right front passenger’s seat, it means that
the passenger sensing system has not turned
off the passenger’s frontal airbag and side
airbag (if equipped). A child in a rear-facing
child restraint can be seriously injured or
killed if the right front passenger’s airbag or
airbags inate. This is because the back of the
rear-facing child restraint would be very close
to the inating airbag or airbags. Do not use
a rear-facing child restraint in the right front
passenger’s seat unless the airbag or airbags
have been turned off.
If the off symbol is not lit on the passenger airbag
status indicator, it means that the right front passenger’s
frontal airbag and seat-mounted side impact airbag
(if equipped) are enabled (may inflate). United
States – Hatchback

{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the airbag(s). SeeAirbag Readiness Light
on page 3-30for more on this, including
important safety information.
Charging System Light
The charging system light
will come on briefly when
you turn on the ignition,
and the engine is not
running, as a check
to show you it is working.
Then it should go out when the engine is started.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
Have it checked by your dealer/retailer. Driving while
this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
3-47

Antilock Brake System
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this
light will come on briefly
when the engine is started.
If it does not come on have your vehicle serviced.
If the light stays on, turn the ignition to LOCK/OFF.
If the light comes on, 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. See your
dealer/retailer. If the regular brake system warning light is
not on, you still have brakes, but you do not have antilock
brakes. If the regular brake system warning light is also
on, you do not have antilock brakes and there is a
problem with your regular brakes. SeeBrake System
Warning Light on page 3-33.
Hold Mode Light
If your vehicle has this
feature, this light comes
on when the hold mode is
active.
If the HOLD mode light flashes, have your vehicle
checked. See “Hold Mode” underAutomatic
Transmission Operation on page 2-21for more
information.
3-48

Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure that emissions are at acceptable levels for the life of
the vehicle, helping to produce a cleaner environment.
The check engine light
comes on to indicate
that there is an OBD II
problem and service
is required.
Malfunctions often are indicated by the system before
any problem is apparent. This can prevent more serious
damage to your vehicle. This system is also designed
to assist your service technician in correctly diagnosing
any malfunction.
Notice:If you keep driving your vehicle with
this light on, after a while, the emission controls
might not work as well, your vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by your warranty.Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system
of your vehicle or replacement tires that do not
match your vehicle’s original tires can affect your
vehicle’s emission controls and can cause this light
to come on. Modications to these systems could
lead to costly repairs not covered by your warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 5-3.
When the ignition is turned to ON/RUN, this light comes
on and should go out after a few seconds as a check
to show it is working. If the light does not come on, have
it repaired. This light also comes on during a malfunction
in one of two ways:
•Light Flashing— A misfire condition has been
detected. A misfire increases vehicle emissions
and could damage the emission control system
on your vehicle. Diagnosis and service might
be required.
•Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service might be required.
3-49

If the Light Is Flashing
The following can prevent more serious damage to your
vehicle:
•Reduce vehicle speed.
•Avoid hard accelerations.
•Avoid 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/retailer for service as
soon as possible.
If the Light Is On Steady
You might be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install the
cap. SeeFilling the Tank on page 5-7. The diagnostic
system can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap allows
fuel to evaporate into the atmosphere. A few driving trips
with the cap properly installed should turn the light off.
Did you just drive through a deep puddle of water?
If so, your vehicle’s electrical system might be wet.
The condition is usually corrected when the electrical
system dries out. A few driving trips should turn the
light off.
3-50

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. Poor fuel quality causes
the engine not to run as efficiently as designed. You
might notice this as stalling after start-up, stalling when
you put the vehicle into gear, misfiring, hesitation on
acceleration, or stumbling on acceleration — these
conditions might go away once the engine is warmed up.
This will be detected by the system and cause the light to
turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer/retailer can check the vehicle. Your dealer/
retailer has the proper test equipment and diagnostic
tools to fix any mechanical or electrical problems that
might have developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced the battery or if the battery
has run down. The diagnostic system is designed to
evaluate critical emission control systems during normal
driving. This can take several days of routine driving. If
you have done this and your vehicle still does not pass
the inspection for lack of OBD system readiness, your
dealer/retailer can prepare the vehicle for inspection.
3-51

Oil Pressure Light
If your vehicle has low
engine oil pressure, this
light will stay on after
you start your engine,
or come on when you
are driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have
some other oil problem. Have it fixed immediately
by your dealer/retailer.
The oil light could also come on in three other situations:
•When the ignition is on but the engine is not running,
the light will come on as a test to show you it is
working. The light will go out when you turn the
ignition on. If it does not come on with the ignition
on, you may have a problem with the fuse or bulb.
Have it fixed right away.
•If you make a hard stop, the light may come on for a
moment. This is normal.
{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.
