P Parking lock.
The parking lock is an additional
safeguard to the parking brake
when parking the vehicle. En­
gage only with the car stopped.
Note:
The key can be removed from the
steering lock only with the selector
lever in position "P" . The selector
lever is locked in position "P" with
the key removed.
Ft Reverse gear.
Shift to reverse gear only with the
car stopped.
Neutral.
No power is transmitted from the
engine to the rear axle. When the
brakes are released, the vehicle
can be moved freely (pushed or
towed). Do not engage "N" while
driving except to coast when the
vehicle is in danger of skidding
(e.g. on icy roads, see page 17).
D The transmission automatically
upshifts to 4th gear. Position "D"
provides optimum driving charact­
eristics under all normal operating
conditions.
3 Upshift to 3rd gear only. Suitable
for medium range up or down­
grades.
2 Upshift to 2nd gear only. For
driving in mountainous regions.
Since transmission will not shift
up further, this gear selection will
make use of the engine's braking
power.
