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.
The Check Engine indicator 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 your Check Engine light 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 good quality fuel and/or properly installing and securely tightening
the gas cap. After three driving cycles without these or any other
temporary malfunctions present, the Check Engine 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 Check Engine 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.
Instrumentation

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.
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
the Seating and safety restraints
chapter.
Brake system warning (if equipped)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If brake
warning lamp does not illuminate at
this time, seek service immediately.
Also illuminates when the parking brake is engaged. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately.
Anti-lock brake system (ABS) (If equipped)
Momentarily illuminates when the
ignition is turned on and the engine
is off. If the light does not illuminate
momentarily at start up, remains on
or continues to flash, the ABS needs
to be serviced. 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 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 to Exterior bulbs in the Maintenance and care
chapter.
High beams
Illuminates when the high beam
headlamps are turned on.
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.
Engine oil pressure (if equipped)
Illuminates when the oil pressure
falls below the normal range. Stop
the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level and
add oil if needed. Refer to Engine oil in the Maintenance and Care
chapter.
This lamp also illuminates when the ignition is turned to ON and the
engine is off.

Engine coolant temperature
Illuminates when the engine coolant
temperature is high. Stop the
vehicle as soon as safely possible,
switch off the engine and let it cool.
Never remove the coolant
recovery cap while the
engine is running or hot.
Refer to Engine coolant in the Maintenance and care chapter. If light
stays on or continues to turn on after the vehicle warms up, have your
vehicle serviced.
This light also illuminates briefly when the ignition key is turned to ON.
Air suspension (if equipped)
This light tells you if the air
suspension needs repair or if the air
suspension switch is OFF. For
information on the air suspension
system, refer to the Driving
chapter.
O/D off
Illuminates when the transmission
control switch has been pushed.
When the light is on, the
transmission does not shift into
overdrive. If the light does not come

GAUGES
Standard instrument cluster gauges
Optional instrument cluster gauges
Fuel gauge
Displays approximately how much fuel is in the fuel tank (when the key
is in the ON position). The fuel gauge may vary slightly when the vehicle
is in motion. The ignition should be in the OFF position while the vehicle
is being refueled. When the gauge first indicates empty, there is a small
amount of reserve fuel in the tank. When refueling the vehicle from
empty indication, the amount of fuel that can be added will be less than
the advertised capacity due to the reserve fuel.

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 9.5 liters (2.5 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:
•80 km (50 miles) left before you run out of fuel
•40 km (25 miles)
•16 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 “CO” or “CS” is displayed, there is a problem with the fuel indication
system and you should contact your dealer for service as soon as
possible.
AVG ECON (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:
•your vehicle was not perfectly level during fill-up
•differences in the automatic shut-off points on the fuel pumps at
service stations
•variations in top-off procedure from one fill-up to another
•rounding of the displayed values to the nearest 0.1 liter (gallons)
