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

Driving and Driving Safety
HOLD function: Drive-Off Assistant and
standstill management The HOLD function assists the driver when
stopping and driving off on upward slopes.
The vehicle is automatically prevented from rolling
back away from the desired direction of travel.
When the HOLD function is active, the function
light on the instrument panel lights up.
When adaptive cruise control is operating
normally, the HOLD function holds the vehicle
following automatic braking until the vehicle is
actively held in a stationary position.
Notes on operation
The HOLD function is no t available if the PDK
selector lever is in position N.
If the PDK selector lever is moved while the
HOLD function is active, the HOLD function is
deactivated.
If the driver’s seat be lt is unbuckled and the
driver’s door is opened wh ile the HOLD function is
active, the electric park ing brake is activated
automatically.
For information on the electric parking brake:
f Please see the chapter “ELECTRIC PARKING
BRAKE” on page 171.
Warning!
In spite of the advantages of the HOLD function, it
is still the driver’s responsibility to adapt his
driving style and maneuvers in line with road and
weather conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greate r risks with your safety.
Caution!
If the vehicle comes to a stop on a steep
uphill gradient without operation of the
footbrake by the driver, this may result in a
certain roll-back before the vehicle is held by
the HOLD function. In this situation, the roll-
back can be reduced by operating the
footbrake.
f Assist holding of the vehi cle by increasing the
brake force with the footbrake.
Brake pedal feels different. When adaptive
cruise control is operating normally or when
the HOLD function is active, the brake pedal
may feel different and you may hear
hydraulic noises.
This behavior is no rmal for the system.
It is not a fault.
Danger!
Risk of accidents. The limits set by physics of
driving cannot be overcome, even with HOLD
function. The responsibi lity for stopping and
driving off on uphill gradients is still the
driver’s, despite the HOLD function.
Assistance by the HOLD function is not
always guaranteed when stopping and
driving off on a slippery surface (e.g. on icy
or loose surfaces). In this case, the vehicle
can slip.
f Always adjust your driving style to the driving
conditions and vehicle load. Use the footbrake
if necessary.
If the Drive-Off Assistant is not functioning,
the driver cannot be assisted when driving
off on hills.
f Hold the vehicle with the footbrake.

ABS Brake System
(Anti-Lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the
driver’s responsibility to adapt his driving style and
maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physic s of driving cannot be
overcome, even with ABS.
Risk of accidents due to inappropriate speed
cannot be reduced by ABS.
ABS ensures
– Full steering control
The vehicle remains steerable
– Good driving stability
No skidding due to locked wheels
– Optimum braking distance
Shorter stopping distance in most cases
– Prevention of wheel locking
No flat spots on the tires Function
The decisive advantage of ABS lies in the driving
stability and maneuverability 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. If the ABS warning light lig
hts up on the instrument
panel while the engine is running, the ABS has
switched off because of a fault.
The warning message “ABS 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.
In this case, the brake system will operate without
lock prevention, as on vehicles without ABS.
f Adapt your driving style to the changed
braking behavior.
The ABS must be checked by your authorized
Porsche dealer in order to prevent the
occurrence of further faults with unpredictable
consequences.
Please contact a qualified specialist workshop.
We recommend that you have 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 no n-approved dimensions can
lead to different wheel speeds, causing ABS to
switch off. Warning light USA
