Trip master ¡
71 This electronic instrument is fitted into the
check panel of 1100SL and 1300SL models
from 1986.

consumption, range, speed and elapsed time.
73 With the ignition key turned to MAR,
figures are displayed in respect of the last
journey - average fuel consumption, average
speed and elapsed time (up to switching off
the ignition).
74 As soon as the engine is started, the
instrument processes the current values to
include fuel consumption, range and the
actual time.
75 Fuel consumption is only displayed when
the road speed exceeds 8.0 km/h (5.0 mph).
76 The fuel range is only displayed after a
road speed of between 25.0 and 70.0 km/h
(15.0 to 44.0 mph) has been maintained for at
least 90 seconds or at higher speeds for
22 seconds.
77 A reset button is provided, also a display
change button (from instant to average or
total values). Should the instrument reading
exceed 99 hours, 59 minutes or 1000 km
(622 miles) depressing the display change
button will display all zeros. Depress button E
to resume normal function.
