Trip computer (option)
The trip computer stores information gathered  from  several systems in your vehicle and  has five menus (six on Canadian
models) that can be  shown in the information display.
MILES TO EMPTY TANK
AVERAGE  (average  fuel consumption)
INSTANTANEOUS  (current fuel consumption)
AVERAGE SPEED
ACTUAL SPEED (current speed in m.p.h., Canadian models only)
DSTC (see page 150)
 NOTE 
Warning messages from  the car's monitoring  systems will override the trip computer function.
If a  warning message is shown in the information display while you are using the trip computer:

Page 55 of 234
Resetting
AVERAGE (average  fuel consumption) and  AVERAGE  SPEED  can be  reset.
1. Select  one  of these functions.
2. Press RESET  (C).
Holding RESET  for at least five seconds resets both functions at the same time.
MILES TO EMPTY TANK
This function shows  the approximate distance that can be  driven on the fuel remaining in the tank. This calculation is
based on average fuel consumption during the last 20 miles (30 km) of driving and  the amount of fuel remaining in the
tank when the reading was taken. When the driving distance on current fuel reserve  is less than 12 miles (20 km), "----"
will be  displayed in the information display.
AVERAGE
This value indicates fuel consumption since the last time the trip computer was reset (by pressing RESET, button C).
When the engine is switched off, information on fuel consumption is stored  and  remains in system memory until the
RESET (button C) is pressed again.
INSTANTANEOUS
This value indicates the current fuel consumption, based on readings taken once per second. When the vehicle is not
moving, "----" will be  displayed.
AVERAGE SPEED
This value indicates average speed since the last time the trip computer was reset (by pressing RESET, button C). When
the engine is switched off, information on average

speed is stored  and  remains in system memory until the RESET (button C) is pressed again.
ACTUAL SPEED (Canadian  models only)
This function provides  the driver with an  instantaneous  conversion of the car's current speed from  km/h to m.p.h.
 NOTE 
Trip computer readings may vary slightly  depending on the circumference of the tires on the car, tire inflation, or
driving style.
