The transmission is provided with a selector switch for
Standard “S” and Winter/Wet (snow and ice) “W”
program modes.
Caution!
Never change the program mode when the selector lever
is out of position “P”. It could result in a change of
driving characteristics for which you may not be
prepared.Important!
Always be certain of the program mode selected since
the vehicle driving characteristics change with the
selection of the program mode.
SStandard mode
Press switch on symbol “S”. Use this mode for all
regular driving.
The vehicle starts out in 1st gear.
Accelerator Operation:
Fast on = depressing the accelerator pedal quickly
(not into kickdown position) while driving
continuously, rather than depressing the
accelerator pedal in the usual manner, will cause
the automatic transmission to shift down into a
lower gear. This gear shifting process is
dependent on the current vehicle speed.
Fast off = there will be no upshift when releasing
the accelerator pedal quickly, e.g. using the
engine’s braking power during performance
driving.
