If the Light is Flashing
The following can prevent more serious damage to
your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the ignition off, wait at least 10 seconds, and restart
the engine. If the light remains on steady, see “If the
Light Is On Steady” following. If the light is still ashing,
follow the previous steps and see your dealer/retailer
for service as soon as possible.
If the Light Is On Steady
You might be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 5-9.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose
or missing fuel cap allows fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water?
If so, your vehicle’s electrical system might be wet.
The condition is usually corrected when the electrical
system dries out. A few driving trips should turn the
light off.

The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to
the number of miles (kilometers) driven since the
ignition was last turned on. This can be used if the trip
odometer is not reset at the beginning of the trip.
To use the retro-active reset feature, press and hold
the set/reset button for at least four seconds. The
trip odometer will display the number of miles (mi)
or kilometers (km) driven since the ignition was last
turned on and the vehicle was moving. Once the
vehicle begins moving, the trip odometer will accumulate
mileage. For example, if the vehicle was driven
5 miles (8 km) before it is started again, and then the
retro-active reset feature is activated, the display
will show 5 miles (8 km). As the vehicle begins moving,
the display will then increase to 5.1 miles (8.2 km),
5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after
the vehicle is started, but before it begins moving,
the display will show the number of miles (mi) or
kilometers (km) that were driven during the last
ignition cycle.RANGE
Press the trip/fuel button until RANGE displays.
This display shows the approximate number of
remaining miles (mi) or kilometers (km) the vehicle
can be driven without refueling. The display will show
LOW if the fuel level is low.
The fuel range estimate is based on an average of
the vehicle’s fuel economy over recent driving history
and the amount of fuel remaining in the fuel tank.
This estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, this display may read one number, but if
the vehicle is driven on a freeway, the number may
change even though the same amount of fuel is in the
fuel tank. This is because different driving conditions
produce different fuel economies. Generally, freeway
driving produces better fuel economy than city driving.
Fuel range cannot be reset.

AVG (Average) ECONOMY
Press the trip/fuel button until AVG ECONOMY displays.
This display shows the approximate average miles
