Trip Computer
The computer memory stores data for a
journey or series of journeys until it is
reset to zero.
The displayed information is for guidance
only, as it can be affected by traffic, road
and weather conditions.
Two independent memories are available
(A and B) to allow two separate journeys
to be recorded concurrently,
for example, work usage and evening/
weekend usage.
Trip distance, average fuel economy and
average speed will be prefixed A or B
depending on the current memory
selected.
Press the TRIP button on the end of the
left column stalk switch repeatedly to
display the data in the following order:
• Odometer.
•Trip distance.
•Range.
• Current fuel consumption.
• Average fuel economy.
• Average speed.
• Messages.
Odometer
The odometer shows the total vehicle
distance travelled since the vehicle was
new.
When the ignition is switched ON
(position ‘II’) the display shows the
odometer reading unless another trip
computer function was previously
selected or a warning message is
displayed, for example, ‘DOOR OPEN’.
The odometer reading is displayed in
either miles or kilometres, depending on
the units selected with the trip computer.
Trip Distance (A/B)
Distance travelled since the last memory
reset. The maximum trip reading is
9999.9 miles (16, 090 kilometres).
The computer, either A or B, will
automatically reset to zero if this distance
is exceeded.
Range
Predicted distance, kilometres or miles,
that the vehicle should travel on the
remaining fuel, assuming average fuel
economy and fuel consumption stay
constant.
