Porsche Active Suspension Management (Pasm) - Porsche cayman gt4 Owner's Manual

Function
The decisive advantage of ABS lies in the driving
stability and manoeuvrability of the vehicle in
hazardous situations.
ABS prevents locking of the wheels during full
braking, on almost all road surfaces, until just
before the vehicle stops.
ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable
with extremely rapid cadence braking.
The pulsating brake pedal and a "juddering noise"
warn the driver to adapt his driving speed to the
road conditions.
f
If full braking is necessary, press the brake
pedal fully during the whole braking operation,
even though the pedal is pulsating. Do not
reduce brake pressure.
Warning light USA
Warning light Canada
If the ABS warning light lights up on the instrument
panel while the engine is running, the ABS has
switched off because of a fault.
The warning message "ABS/PSM failure
Adapted driving permitted" appears on the
multi-function display in the instrument panel.
For information on warning messages on the multi-
function display:
f
Please see the chapter "OVERVIEW OF
WARNING AND INFORMATION MESSAGES"
on page 109.
In this case, the braking system will operate
without lock prevention, as in vehicles without
ABS.
f
Adapt your driving style to the changed
braking behavior.
The ABS must be checked by your Porsche
dealer in order to prevent the occurrence of
further faults with unpredictable
consequences.
Please contact a qualified specialist workshop.
We recommend that you get an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with non-approved dimensions can
lead to different wheel speeds, causing ABS to
switch off.
Porsche Active Suspension
Management (PASM)
The PASM system actively adjusts the shock
absorbers. The adjustable damper system selects
the appropriate damping level for each wheel
according to the driving situation and driving
conditions. Driving safety, agility and comfort are
optimised.
Two different chassis setups can be selected at
the push of a button:
– "Chassis Normal"
– "Chassis Sport"
In Normal mode, the chassis is in a basic setup for
public roads and race circuits with uneven
surfaces.
Sport mode provides a shock absorber tuning for
particularly high driving dynamics (e.g. on even
race circuits).
In addition to manual mode selection, PASM also
adjusts shock absorber tuning for either sporty or
comfort driving, depending on the driving
situation.
Selecting the PASM mode
1. Switch on ignition.
2. Press button (repeatedly).
On the button:
– No indicator light comes on when "Chassis
Normal" is selected (default setting).
– An indicator light comes on when "Chassis
Sport" is selected.
In addition, the selected chassis setup is shown on
the multi-function display in the instrument panel
for approx. 4 seconds.
