2. DESCRIPTION OF COMPONENTS
2.1 SELECTOR LEVER
The various gears of the automatic gearbox are
selected using the selector lever. The selector
lever has four positions for the forward gears
(1, 2, 3 and D), a neutral position (N) and a
reverse position (R).
The neutral position (N) is the usual position for
starting and stopping the engine and for longer
stationary periods when the engine is idling. The
gearbox must not be put in the neutral position
when driving.
In the drive position (D) the gearbox automatically
changes up and down in all forward gears.
In positions (1), (2) and (3) the gearbox changes
up as far as the selected gear. These positions
can be used to keep the engine in the correct rev
band or to obtain maximum engine brake
performance.
To reverse, the selector lever must be in the (R)
position. A warning signal is also activated when
reversing.
