Global Reset
If the RESET button is pressed twice within 4 seconds
while in any of the 3 resettable displays, the Global Reset
will reset all 3 displays.
Step Button
Use this button to choose or cycle through the four trip
conditions.
Average Fuel Economy (AVG ECO)
Shows the average fuel economy since the last reset. This
display mode becomes less sensitive to instantaneous
changes in fuel consumption as the number of total
vehicle miles since the last reset increases. It is suggested
that this mode be reset periodically for general operation
or when driving conditions change significantly (for
example, at the end of a trip or when a trailer is
connected or disconnected).
Distance To Empty (DTE)
Shows the estimated distance that can be travelled with
the fuel remaining in the tank. The estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level.
When Distance To Empty = 0, the fuel gauge pointer will
initially be on the red ªEº marker. At this point (fuel
gauge pointer on the red ªEº marker) there is reserve fuel

2. EconomyÐ
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Underinflation also increases tire
rolling resistance and results in higher fuel consumption.
3. Ride Comfort and Vehicle StabilityÐ
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure for passenger cars
is listed on either the face of the driver's door or the
driver's side ªBº pillar. For vehicles other than passenger
cars, the cold tire inflation pressures are listed on either
the ªBº pillar, the Certification Label or in the Tire
Inflation Pressures brochure in the glove compartment.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than themaximum loaded vehicle condition. These pressure con-
ditions will be found in the ªSupplemental Tire Pressure
Informationº section of this manual.
The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to
