Automatic drive program
Drive program C is characterized by the
following:
R comfort-oriented engine and transmission
settings
R optimal fuel consumption resulting from
the transmission shifting up sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
R increased sensitivity; this improves driving
stability on slippery road surfaces, for
example
R the transmission shifting up sooner; this
results in the vehicle being driven at lower
engine speeds and the wheels being less
likely to spin
Drive programs S and S+ are characterized
by the following:
R sporty engine and transmission settings
R the transmission shifting up later and
shifting down dynamically
