following is a list of all possible menu items:
Digital Speed : Displays how fast the vehicle is moving in either kilometers per hour (km/h) or miles per hour (mph). The speedometer cannot be reset.
Trip 1 or Trip 2, Average Fuel Economy : Displays the current distance traveled, in either kilometers (km) or miles (mi), from the last reset for the trip odometer. The trip odometer can be reset to zero by pressing and holding the SET/CLR button while the trip odometer display is showing.
Also displays the approximate average liters per 100 kilometers (L/100 km) or miles per gallon (mpg). This number is based on the number of L/100 km (mpg) recorded since the last time this menu item was reset. This number reflects only the approximate average fuel economy that the vehicle has right now, and will change as driving conditions change. Reset the average consumption by pressing SET/CLR when it is displayed.
Fuel Range : Displays the approximate distance the vehicle can be driven without refueling. 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. Fuel range cannot be reset.
Average Vehicle Speed : Displays the average vehicle speed of the vehicle in kilometers per hour (km/h) or miles per hour (mph). This average is based on the various vehicle speeds recorded since the last reset. Reset the average speed by pressing SET/CLR when it is displayed.
Timer : To start the timer, press SET/CLR while Timer is displayed. The display will show the amount of time that has passed since the timer was last reset, not including time the ignition is off.
