Service indicator
This information is displayed for a few
seconds after switching on the igni-
tion. It informs the driver when the next
service is due, in accordance with the
manufacturer's servicing schedule.
The point at which the service is due is
calculated from the last service indica-
tor zero reset. It is determined by two
parameters:
- the distance travelled,
- the time elapsed since the last service.
More than 1 800 miles (3 000 km)
remain before the next service is due
When the ignition is switched on, no
service information appears in the in-
strument panel central screen.
Between 600 miles (1 000 km) and
1 800 miles (3 000 km) remain
before the next service is due
For a few seconds after the ignition is
switched on, the spanner symbolising
the service operations comes on. The
distance recorder display line or a spe-
cifi c message in the instrument panel
central screen indicates the distance re-
maining before the next service is due.
For example:
1 700 miles (2 800 km)
remain before the next service is due.
For a few seconds after the ignition is
switched on, the screen indicates:
Less than 600 miles (1 000 km) remain
before the next service is due
Example:
560 miles (900 km) remain
before the next service is due.
For a few seconds after the ignition is
switched on, the screen indicates:
A few seconds after the ignition is
switched on, the spanner goes off
; the
distance recorder resumes its normal
operation. The screen then indicates
the total and trip distances. A few seconds after the ignition is
switched on, the distance recorder
resumes its normal operation. The
spanner remains on
to indicate that a
service must be carried out soon.
