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

that the vehicle should travel on the
remaining fuel, assuming average fuel
economy and fuel consumption stay
