Switching off PSM

  • Press button .
    PSM is switched off after a short delay.
    The light-emitting diode in the button is lit up.
    When PSM is switched off, the PSM OFF warning light on the instrument panel lights up and a message appears on the multi-function display of the instrument panel.

With increased braking power, the vehicle is stabilized even when PSM is switched off.

One-sided spinning of the wheels is prevented, even with PSM switched off.

PSM should always be switched on during "normal" driving.
However, it may be a good idea to switch off PSM temporarily in exceptional situations:

  1. on a loose surface (e.g. on sand)
  2. in deep snow,
  3. when "rocking the vehicle free" and
  4. when using snow chains.

Information
When PSM is switched off, wheel-specific brake interventions and the anti-slip regulation system (ASR) are also inactive.

The automatic brake differential (ABD) remains on.


Switching PSM back on

  • Press button .
    PSM is active immediately.
    The light-emitting diode in the button and the PSM OFF warning light on the instrument panel go out.
    The message "PSM on" appears on the multifunction display of the instrument panel.

PSM warning light

  1. The PSM warning light on the instrument panel lights up for a lamp check when the ignition is switched on.
  2. The light indicates a control operation, even when PSM is switched off, e.g. brake control in the event of one-sided wheel spin.
  3. The light - in conjunction with the multi-function display - indicates a fault.
    The warning message "PSM failure" appears on the multi-function display of the instrument panel.

For information on warning messages on the multi-function display:

  • Please see the chapter "OVERVIEW OF WARNING MESSAGES AND INFORMATION" on page 140.
  • Adapt your driving style according to the changed conditions.
  • Consult your authorized Porsche dealer.
