Automatic Transmission
The automatic transmission
selects individual gears auto-
matically, dependent upon
Selector lever position
Accelerator position
Vehicle speed
Important!
When parking the car or before
working on the vehicle with the
engine running, firmly depress the
parking brake pedal and shift the
selector lever into "P".
Driving
The selector lever is automatically
locked while in position "P". To
move the selector lever out of position
"P", the service brake pedal must be
firmly depressed before the shift lock
will release.
Shift selector lever to the desired
driving position only when the engine
is idling and the service brake is
applied. Do not release the brake until
ready to drive. The vehicle may
otherwise start creeping when the
selector lever is in drive or reverse
position.
Warning!
It is dangerous to shift the selector
lever out of "P" or "N" if the engine
speed is higher than idle speed. If
your foot is not on the brake pedal,
the car could accelerate quickly
forward or in reverse. You could lose
control of the car and hit someone or
something. Only shift into gear when
the engine is idling normally and
when your right foot is firmly on the
brake pedal.
Important!
After selecting any driving position
from "N" or "P", wait a moment to
allow the gear to fully engage before
accelerating, especially when the
engine is cold.
Accelerator position
Partial throttle = early upshifting
= normal acceleration
Full throttle = later upshifting
= rapid acceleration
Kickdown (depressing the accelerator
beyond full throttle) = downshifting
to next lowest gear = maximum
acceleration. Once the desired speed
is attained, ease up on the accelerator
- the transmission shifts up again.
