Driving and Driving Safety

Transmission and Chassis Control SystemsYour Porsche features a complex integrated system made up of all control systems acting in power transmission and in the chassis.
All control systems are networked with the aim of combining the best possible driving performance with maximum safety.
The following systems are invo lved, depending on equipment:
System/designation Scope
PTM
Porsche Traction Management – Active all-wheel drive with electronically
regulated map-controlled multiple-disc clutch
PSM
Porsche Stability Management – Driving stability control
– Anti-lock brake system (ABS)
– Brake system prefilling
– Brake booster (Hydraulic Brake Assist)
– Automatic brake differential (ABD)
– Anti-slip control (ASR)
– Engine drag torque control (MSR)
– HOLD function: standstill management
Air suspension
with level control and height adjustment – Full load-bearing air-spring stru
ts with integrated shock absorbers
– Height adjustment with Low Level setting in “S port Plus” mode and High Level setting for
maneuvering
PAS M
Porsche Active Suspension Management – Shock absorber system with adaptive, continuous shock absorber control
PDCC
Porsche Dynamic Chassis Control – Active chassis control system to stabilise
roll tendency of vehicle body when driving
– Controlled rear differential lock

204
Driving and Driving Safety
– Brake system prefilling:
The brake system is prepared for possible
subsequent emergency braking if the
accelerator pedal is released suddenly and
quickly. The brake system is prefilled and the
brake pads are already applied gently to the
brake discs.
– Brake booster (Hydraulic Brake Assist): In the event of an emergency braking operation
where the pedal force is insufficient, a brake
booster provides the braking pressure
necessary for maximum deceleration at all
4wheels.
Combined operation of PSM and PTM
In order to ensure optimum stabilisation of the
vehicle, torque distribution between the front and
rear wheels is adapted and the rear differential
lock is controlled on vehicles with PDCC.
In the event of a PTM fault, PSM cannot be
switched off.
If PSM is switched off, it is switched on again
automatically. Automatic brake differential (ABD)
The ABD system controls the front and rear axles
separately. If one wheel of an axle starts to spin,
it is braked so that the other wheel on the same
axle can be driven.
ABD recognizes different driving states, and it
features control strategies adapted to these
states. In situations in which little propulsive power
is required, such as when the vehicle moves off on
a level gravel surface, traction control already
becomes active at low engine speeds. If a large
amount of propulsive power is required, e.g. when
driving off on an uph
ill slope or for rapid
acceleration, the ABD system is adapted
accordingly.
Anti-slip control (ASR)
The anti-slip control system prevents the wheels
from spinning by adjusting the engine power,
thereby ensuring good lane-holding ability and
stable handling.
Engine drag torque control (MSR)
In conditions of excessive slip, the engine
drag torque control system prevents all driven
wheels from locking up when the vehicle is
overrunning. This is also the case for downshifts
on a slippery road.
Switching off PSMf Press button for at least 1 second.
PSM is switched off after a short delay.
The indicator light on the button and the
PSM OFF warning light on the instrument
panel light up.
The warning “PSM off” appears on the
multi-function display in the instrument panel.

Driving and Driving Safety
205
When you brake in the ABS control range,
the vehicle is stabilised 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.
H o w e v e r, i t m a y b e a g o o d i d e a to s w it c h o f f P S M
temporarily in exceptional situations:
– On a loose surface and in deep snow.
– When “rocking the vehicle free”.
– When using snow chains.
Tip on driving
The vehicle retains its enhanced braking readiness
through prefilling of the br ake system even when
PSM is switched off.
When PSM is switched off, wheel-specific brake
interventions and the anti-slip control system (ASR)
are also switched off.
The automatic brake differential (ABD) remains on.
Adaptive cruise control is deactivated when PSM
is switched off.
When PSM is switched off, the slip monitoring
function of Porsche Doppelkupplung (PDK) is also
deactivated.
Switching PSM back onf Press button .
PSM is active immediately.
The indicator light on the button and the
PSM OFF warning light on the instrument
panel go out.
The message “PSM switched on” appears on
the multi-function disp lay in the instrument
panel.“Sport Plus” modeA sportier setup is obtained when “Sport Plus”
mode is switched on.
PSM interventions occur later than in Normal
mode. The vehicle can be maneuvered with
greater agility at its pe rformance limits, without
having to dispense with th e assistance of PSM in
emergency situations. This helps to achieve
optimal lap times, particular ly on race circuits and
on a dry road surface. – The PSM warning light on the instrument panel
lights up for a lamp check when the ignition is
switched on.
– The light indicates a control operation, even when PSM is switched off, e.g. brake control in
the event of one-sided wheel spin.
– The light - in conjunction with the multi-function display - indicates a fault.
The warning message “PSM failure” 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 MESSAGES” on page 152.
f Adapt your driving style according to the
changed conditions.
f Contact a qualified spec ialist workshop in
order to correct the fault. We recommend that
you have an authorized Porsche dealer to do
this work, as they have the trained workshop
personnel and the necessary parts and tools
for this type of work.
