MILES TO EMPTY TANK
This function shows the approximate distance
that can be driven on the fuel remaining in the

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 message ---- miles to empty tank
appears in the display, refuel as soon as pos-
sible.

ing

switched off, information on fuel consumption
is stored and remains in system memory until

INSTANTANEOUS
This value indicates the current fuel consump-
tion, based on readings taken once per sec-
ond. When the car is not moving, "
---- " will be
displayed.
AVERAGE SPEED
This value indicates average speed since the
last time the trip computer was reset, by press-
ing
RESET (button 3). When the engine is
switched off, information on average speed is
stored and remains in system memory until the
RESET (button 3) is pressed again.
