Introduction

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.
If the light remains ON while driving, the temperature of the engine may
be too high, refer toEngine coolantin theMaintenance and
Specificationschapter.
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.
Powertrain malfunction
indicator:Illuminates when a
powertrain or a AWD fault has been
detected. Contact your authorized
dealer as soon as possible.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position
when the engine is not running, or in a position between ON and START,
or by applying the parking brake when the ignition is turned to the ON
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level and the
brake system should be inspected immediately by your authorized dealer.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your authorized dealer. Driving extended distances with
the parking brake engaged can cause brake failure and the risk of
personal injury.

ensure the bulb is working. If the light does not turn ON, have the
system inspected by your authorized dealer. For more information on
this system, refer toUnderstanding your Tire Pressure Monitoring
Systemin theTires, Wheels and Loadingchapter.

the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Service

Average fuel economy (AFE)
Select this function from the INFO
menu to display your average fuel
economy in miles/gallon or liters/km.
If you calculate your average fuel
economy by dividing miles 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 RESET control (press and hold RESET for 2
seconds in order to reset the function) after setting the speed control to
get accurate highway fuel economy readings.
Instantaneous fuel economy
Select this function from the INFO
menu to display your instantaneous
fuel economy. This will display your
fuel economy as a Bar Graph
ranging from
poor fuel economy
to
excellent fuel economy. As
the bars increase from left to right,
the instantaneous fuel economy is
increasing.
Your vehicle must be moving to calculate instantaneous fuel economy.
When your vehicle is not moving, this function shows one or no bars
illuminated. Instantaneous fuel economy cannot be reset.
