Driving the Automatic Transmission
There are a few points you should know if
you want to take full advantage of the Auto-
matic Transmission.
...Apply the parking brake or foot brake
before selecting a driving range. When the
selector lever is in a driving range, the car
may creep even at idle speed. Therefore, do
not release the parking brake or foot brake
until you are ready to move.
... Do not accelerate while selecting a driv-
ing range. At this time the engine must run
at idle speed so that no undue stress will be
placed on the automatic clutches in the
transmission.
... Do not move the selector lever into
Neutral (N) at driving speeds above 30 mph
or 50 km/h.
If the selector lever is unintentionally moved
into Neutral (N) while driving, take your foot
off the accelerator pedal and wait until the
engine speed has dropped to idling before
selecting a driving range.
The driving ranges
The Automatic Transmission has 3 forward
driving ranges and one reverse. In the driv-
ing ranges D and 2 the Automatic Trans-
mission changes gears automatically while
driving.
Position D
is the driving range to be normally used for
day-to-day driving and highway driving. It
ranges from zero to top speed, and all three
gears engage automatically while driving.
Position 2 and 1
are to be used for mountain driving or slow
driving, and also when you want to make use
of the engine's braking effect.
Position 2
should only be used to 95 mph or 150 km/h.
In " 2 " , only the first and second gears will
engage automatically. Therefore, only shift
down into driving range " 2 " when the speed
is below 80 mph or 130 km/h. It is not neces-
sary to let up on the accelerator.
Position 1
is needed on rare occasions. It should only
be used up to 65 mph or 105 km/h. In " 1 " the
transmission will stay in first gear and not
shift into the second or third gear. Only shift
down into " 1 " when the car speed is below
45 mph or 75 km/h.
The reverse driving range
The reverse driving range should be select-
ed only when the car has come to a full stop
and the engine is running at idle speed. At
driving speeds above 10 mph or 15 km/h, a
hydraulic lock prevents the driver from un-
intentionally moving the selector lever into
position R or P.
The back-up lights come on automatically
when you engage Reverse (with ignition on).
Starting the engine
is only possible when the selector lever is in
Neutral or in Park. As long as one of the
driving ranges is engaged a safety switch
prevents the engine from being started.
