WARNING LIGHTS AND CHIMES
Check engine
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This
system is commonly known as the
On Board Diagnostics System
(OBD II). This OBD II system protects the environment by ensuring that
your vehicle continues to meet government emission standards. The
OBD II system also assists the service technician in properly servicing
your vehicle.
TheCheck Engineindicator light illuminates when the ignition is first
turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine's emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.
What you should do if the check engine light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourCheck Enginelight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.

3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the gas cap. After three driving cycles
without these or any other temporary malfunctions present, theCheck
Enginelight should turn off. (A driving cycle consists of a cold engine
startup followed by mixed city/highway driving.) No additional vehicle
service is required.
If theCheck Enginelight remains on, have your vehicle serviced at the
first available opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Check fuel cap
Momentarily illuminates when the
ignition is turned to the ON position
to ensure your bulb is working.
When this light turns on, check the
fuel filler cap. Continuing to operate the vehicle with the check fuel cap
light on, can activate theService Engine Soon/Check Enginewarning
light. When the fuel filler cap is properly re-installed, the light(s) will
turn off after a period of normal driving. This period will vary depending
on driving conditions.
It may take a long period of time for the system to detect an
improperly installed fuel filler cap.
For more information, refer toFuel filler capin theMaintenance and
carechapter.

Air bag readiness
Momentarily illuminates when the
ignition is turned ON. If the light
fails to illuminate, continues to flash
or remains on, have the system
serviced immediately.
Safety belt
Momentarily illuminates when the
ignition is turned to the ON position
to remind you to fasten your safety
belts. For more information, refer to
theSeating and safety restraints
chapter.
Brake system warning
Momentarily illuminates when the
ignition is turned to the ON position
to ensure the circuit is functional.
Also illuminates if the parking brake
is engaged. If the brake warning
lamp does not illuminate at these times, seek service immediately.
Illumination after releasing the parking brake indicates low brake fluid
level and the brake system should be inspected immediately.
Anti-lock brake system (ABS)
Momentarily illuminates when the
ignition is turned to the ON position
to ensure the circuit is functional. If
the light remains on, continues to
flash or fails to illuminate, have the
system serviced immediately. With the ABS light on, the anti-lock brake
system is disabled and normal braking is still effective unless the brake
warning light also remains illuminated with the parking brake released.

Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. If one or both of the
indicators stay on continuously or
flash faster, check for a burned-out
turn signal bulb. Refer toBulbsin theMaintenance and carechapter.
High beams
Illuminates when the high beam
headlamps are turned on.
Anti-theft system (if equipped)
Refer toSecuriLockypassive
anti-theft systemin theControls

Charging system
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when the battery is not
charging properly, requiring
electrical system service.
Check gage
Illuminates when the engine coolant
temperature is high, the engine oil
pressure is low or the fuel gauge is
at or near empty. The ignition must
be in the ON position for this lamp to illuminate. The lamp will also stay
illuminated after the ignition is turned to the ON position. Refer to
Engine coolant temperature gauge, Engine oil pressure gaugeor
Fuel gaugein this chapter for more information.

Four wheel drive low (if equipped)
Momentarily illuminates when the
ignition is turned to the ON/START
position. Illuminates when
four-wheel drive low is engaged. If
the light continues to flash have the system serviced.
Four wheel drive high (if equipped)
Momentarily illuminates when the
ignition is turned to the START
position. Illuminates when
four-wheel drive high is engaged. If
the light continues to flash have the system serviced.
Door ajar

pushed turning the transmission overdrive function OFF. When the light
is on, the transmission does not operate in the overdrive mode, refer to
theDrivingchapter for transmission function and operation.
The light may also flash steadily if a transmission malfunction is
detected. If the light does not come on when the Transmission Control
Switch is depressed or if the light flashes steadily, have your vehicle
serviced as soon as possible, damage to the transmission could occur.
Check air suspension (if equipped)
Illuminates momentarily when the
ignition is turned to the ON position
and the engine is OFF. The light
also illuminates when the air suspension system requires servicing.

Radio frequency information
The Federal Communications Commission (FCC) and the Canadian Radio
and Telecommunications Commission(CRTC) establish the frequencies
AM and FM stations may use for their broadcasts. Allowable frequencies
are:
AM 530, 540±1600, 1610 kHz
FM 87.7, 87.9±107.7, 107.9 MHz
Not all frequencies are used in a given area.
Radio reception factors
Three factors can affect radio reception:
²Distance/strength.The further an FM signal travels, the weaker it is.
The listenable range of the average FM station is approximately 40 km
(24 miles). This range can be affected by ªsignal modulation.º Signal
modulation is a process radio stations use to increase their
strength/volume relative to other stations.
²Terrain.Hills, mountains and tall buildings between your vehicle's
antenna and the radio station signal can cause FM reception problems.
Static can be caused on AM stations by power lines, electric fences,
traffic lights and thunderstorms. Moving away from an interfering
structure (out of its ªshadowº) returns your reception to normal.
²Station overload.Weak signals are sometimes captured by stronger
signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.
The audio system automatically switches to single channel reception if it
will improve the reception of a station normally received in stereo.
Audio system warranties and service
Refer to the ªWarranty Guideº for audio system warranty information.
If service is necessary, see your dealer or a qualified technician.
