Sport mode
A sportier car set-up is obtained when Sport or
Sport Plus mode is switched on.
PSM interventions are later than in Normal mode;
the vehicle can be maneuverd with greater agility
at its performance limits, without dispensing with
the assistance of PSM in emergency situations.
This helps to achieve optimal lap times, particu-
larly on race circuits and a dry road surface.
PSM multifunctional light
– The multifunctional light on the instrument
panel lights up for a lamp check when the
ignition is switched on.
– The light indicates a control operation by
flashing, including when PSM is switched off
(brake control in the event of one-sided wheel
spin).
– In conjunction with a message on the on-board
computer, the light indicates that PSM is
switched off.
An acoustic signal also sounds.
– The light indicates a fault in conjunction with a
message on the on-board computer.
PSM is out of order.
f Please have the fault remedied at an author-
ized Porsche dealer.
