138 Instruments and Controls
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’s ability to pass
an Emissions Inspection/
Maintenance test. See
Accessories and Modifications
0285.
If the light is flashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service
may be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades. If towing a trailer, reduce the
amount of cargo being hauled as
soon as possible.
If the light continues to flash, find a
safe place to park. Turn the vehicle

amount of fuel remaining in the fuel
tank. Fuel range cannot be reset.
Average Fuel Economy
The Average Fuel Economy display
shows the approximate average
liters per 100 kilometers (L/100 km)
or miles per gallon (mpg). This
number reflects only the
approximate average fuel economy
that the vehicle has right now, and
will change as driving conditions
change. This number is based on
the number of L/100 km (mpg)
recorded since the last time this
menu item was reset. Reset this
display by pressing the trip
