Check engine
Illuminates briefly to ensure the
system is functional. 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 and will
not require towing.
Light turns on solid:
Temporary malfunctions may cause your light to illuminate. Examples
are:
1. The vehicle has run out of fuel.
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 fuel cap. After three driving cycles
without these or any other temporary malfunctions present, the light
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 the light 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
Illuminates when the fuel cap is not
installed correctly. Check the fuel
cap for proper installation. When
the fuel filler cap is properly
re-installed, the light(s) will turn off
after a period of normal driving. Continuing to operate the vehicle with
the check fuel cap light on, can activate theService Engine Soon/Check
Enginewarning light.
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
specificationschapter.
Brake system warning
²Standard instrument cluster
²Optional instrument cluster
Illuminates if the parking brake is
engaged. Also momentarily
illuminates at start up to ensure the
circuit is functional. If the brake
warning lamp does not illuminate at these times, or illuminates after
releasing the parking brake, seek service immediately. Refer toBrakesin
theDrivingchapter for more information.
Anti-lock brake system (ABS) (If equipped)
Momentarily illuminates at start up
to ensure the circuit is functional. If
the light does not illuminate,
remains on or continues to flash, the
ABS needs to be serviced (refer to
Brakesin theDrivingchapter for more information). With the ABS light
on, the ABS is disabled and normal braking is still functional.

Engine coolant temperature gauge
Indicates the temperature of the engine coolant. At normal operating
temperature, the needle remains within the normal area (the area
between the ªHº and ªCº). If it enters the red section, the engine is
overheating. Stop the vehicle as soon as safely possible, switch off the
ignition and let it cool. Refer toEngine coolantin theMaintenance
and specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
²Standard instrument cluster
²Optional instrument cluster
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the engine
coolant andCheck Engine/Service Engine Soonindicators illuminate,
refer toWhat you should know about fail-safe coolingin the
Maintenance and specificationschapter.

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 theWarranty Guidefor audio system warranty information.
If service is necessary, see your dealer or a qualified technician.

AIMING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident the alignment of your headlamps
should be checked by a qualified service technician.
TURN SIGNAL CONTROL
²Push down to activate the left
turn signal.
²Push up to activate the right turn
signal.
The flash rate of the turn signal will speed up considerably if the left or
right turn lamp bulb (front or rear) is burned out.
Cornering lamps
When the turn signal is used and the headlamps are on, the cornering
lamps will light either the right or left side depending on the direction of
the turn.

Message center functions
DISTANCE TO EMPTY (DTE)
This function estimates
approximately how far you can drive
with the fuel remaining in your tank
under normal driving conditions.
Remember to turn the ignition OFF
when refueling your vehicle. Otherwise, the display will not show the
addition of fuel for a few miles. At least four gallons of fuel must be
added for the fuel gauge to immediately show the new fuel level.
The DTE function will flash for 5 seconds and sound a tone for 1 second
when you have approximately:
²80 km (50 miles) left before you run out of fuel
²40 km (25 miles)
²16 km (10 miles)
The message center will remain in
the DTE function until the SELECT
control is pressed to change
functions.
Displayed DTE will not be equal to
AVG ECON multiplied by the FUEL
REMAIN value. DTE is calculated
using a method that considers the
fuel economy of the last 800 km
(500 miles) driven.
If ªCOº or ªCSº is displayed, there is a problem with the fuel indication
system and you should contact your dealer for service as soon as
possible.

AVG FUEL ECONOMY (average fuel economy)
Select this function to display your
average fuel economy in liters/100
km or miles/gallon.
If you calculate your average fuel
economy by dividing miles traveled by gallons used, your figure may be
different than displayed for the following reasons:
²your vehicle was not perfectly level during fill-up
²differences in the automatic shut-off points on the fuel pumps at
service stations
²variations in top-off procedure from one fill-up to another
²rounding of the displayed values to the nearest 0.1 liter (gallons)
Press the RESET control while AVG
ECON is displayed to reset the
function.
