Selector positions
D
This is the gear to select for normal driving.
The three forward gears are automatically
engaged, according to the load on the
engine and the speed of the vehicle.
2
This is the gear to select for mountainous
terrain, as well as for long uphill or downhill
stretches. The engine's power is better uti­
lised, and also the retardation affect of the
engine is greater. The vehicle pulls away in
1st gear and changes automatically into 2nd
gear. 3rd gear is locked out. During driving,
this position can be selected, even with the
accelerator depressed. However, as 2nd
gear is then immediately engaged, this
should not be done at speeds in excess of
150 km/h (90 mph).

1
This position should be selected when it ap­
pears advisable to hold the vehicle in 1st
gear, e. g. steep up- or downhill stretches, or
when operating with a trailer in mountainous
terrain.
The vehicle remains in 1st gear, and 2nd and
3rd gears are locked out.
This position can be selected from position
2 during driving by pressing the lock-out but­
ton, but should only be done at speeds
lower than 60 km/h (35 mph).
Ρ
Must only be selected when the vehicle is
stationary.
In this position, the driving wheels are me­
chanically locked. To select Ρ the lock-out
button must be pressed.
Ρ should only be selected after the hand­
brake has been applied, and should be dis­
engaged before the handbrake is released.
The engine can be started in this position.
Ν
In this selector position, no gears can be
engaged. It is the same as neutral in a man­
ual gearbox, and should be selected when
the vehicle is stationary for any length of
time, e. g. traffic jam. This position should
only be selected when the engine r. p. m. are
at tick-over.
The engine can be started in this position.
R
This position must only be selected at tick-
over, and with the vehicle stationary. The
lock-out button has to be pressed to select
R. At speeds in excess of 15 km/h (10 mph) a
hydraulically operated lock-out prevents R
and Ρ from being engaged. With the ignition
on, the reversing lights come on automatic­
ally when R is selected.
