202 Driving and Operating
To Accelerate
To accelerate when the accelerator
pedal is pressed further, kickdown
operates and the speed increases.
The transmission will downshift at
speeds below 88 km/h (55 MPH) for
diesel vehicles, and below
112 km/h (70 MPH) for gasoline
vehicles, to provide greater
acceleration.
Kickdown
If you press the accelerator pedal
fully while driving, in accordance
with the current speed the gear
automatically shifts down and the
engine speed rises, enabling
sufficient acceleration. This is called
kickdown.
You can easily accelerate to the
required speed when overtaking
other vehicles or when joining traffic
on a highway. In order to maintain
speed when driving on an uphill
road, as you gradually press the
accelerator pedal the engine may
automatically shift down in
accordance to the current speed
(shifts to a lower speed gear),
increasing the engine speed and
increasing vehicle speed.
Driving Uphill or Downhill
Uphill driving:
With the selector lever in D (diesel
engine) or D6/D4 (gasoline engine),
if you press down on the accelerator
pedal, kickdown (change to a low
speed gear) may operate causing
the engine revolutions to suddenly
increase (increasing the speed).
Driving for a prolonged duration on
an uphill road with the selector lever
in D (diesel engine) or D6/
D4 (gasoline engine) may cause the
automatic transmission fluid to
overheat.
For vehicles with a diesel engine,
drive with the overdrive off switch
ON to keep the engine revolutions
constant to enable smoother driving
with fewer changes in engine
revolutions.
For vehicles with a gasoline engine,
drive with the selector lever in the
D4 position to keep the engine
revolutions constant to enable
smoother driving with fewer
changes in engine revolutions.
