pressure value shown on the Tire
and Loading Information label. See
Tire Pressure on page 10-51.
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a

Trip A or Trip B: Shows the
current distance traveled, in either
kilometers (km) or miles (mi), since
the trip odometer was last reset.
This also shows the approximate
average liters per 100 kilometers (L/100 km) or miles per
gallon (mpg). This number is
calculated based on the number of L/100 km (mpg) recorded since the
last time this menu item was reset.
This number reflects only the

average of fuel economy for the
most recently traveled selected
distance. Displayed below the bar
graph is the best average fuel
economy that has been achieved for
the selected distance. The selected
distance is displayed at the top of
the page as “last xxx mi/km.” Next
to the odometer, the Active Fuel
Management displays the number of
cylinders the vehicle is running on.
