Service engine soon:TheService
engine soonindicator light
illuminates when the ignition is first
turned to the on position to check
the bulb and to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. Normally, the “Service engine
soon” light will stay on until the engine is cranked, then turn itself off if
no malfunctions are present. However, if after 15 seconds the “Service
engine soon” light blinks eight times, it means that the vehicle is not
ready for I/M testing. See theReadiness for Inspection/Maintenance
(I/M) testingin theMaintenance and Specificationschapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.
WARNING: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.

ENG HRS
Registers the accumulated time the engine has been running.
MILES (km) TO E
This displays an estimate of 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 to allow this feature to
correctly detect the added fuel.
This function will display LOW FUEL LEVEL when you have
approximately 50 miles (80 km), to empty. Press RESET to clear this
warning message. It will return at approximately 25 miles (40 km),
10 miles (16 km) and 0 miles (0 km) to empty.
The distance to empty is calculated using a running average fuel
economy, which is based on your recent driving history of 500 miles
(800 km). This value is not the same as the average fuel economy
display. The running average fuel economy is re-initialized to a factory
default value if the battery is disconnected.
XX.X MPG (L/100km)
Average fuel economy displays your average fuel economy in miles/gallon
or liters/100 km.
If you calculate your average fuel economy by dividing distance traveled
by gallons of fuel used (liters of fuel used by 100 kilometers traveled),
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 gallon (liter)
1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the SELECT/RESET button (press and hold the
SELECT/RESET button for two seconds in order to reset the function)
after setting the speed control to get accurate highway fuel economy
readings.
