Driving and Driving Safety
Brake boosterThe brake booster assists braking only when
the engine is running.
When the car is moving while the engine is not
running, or if the brake booster is defective, more
pressure on the brake pedal is required to bring
the car to a stop.
Moisture, road salt or grit on brakes affects
braking.
Brakes will dry after a few cautious brake
applications.
Warning!
Risk of an accident, resulting in serious
personal injury or death.
Driving through water may reduce the
traction. Moisture on brakes from road
water, car wash, or a coating of road salt or
grit may affect braking efficiency.
f Cautiously apply brakes to test brakes after exposure to road water, etc.
Brake wearYour car has excellent brakes, but they are still
subject to wear. The rate at which they wear
depends on how the brakes are used.
f Have the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the “On” position (position 1) and verifying that the
warning light illuminates.
A warning message will be displayed on the multi-
function display of the instrument panel if the
brake pads are worn, excessively.
f Do not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
Brake pads and brake discsWear on the brake pads and brake discs depends
to a great extent on the driving style and the
conditions of use and therefore cannot be
expressed in actual miles on the road.
The high-performance brake system is designed
for optimal braking effect at all speeds and
temperatures.
Certain speeds, braking forces and ambient
conditions (e.g. temperature and humidity) can
therefore cause the brakes to “squeal”.
New brake pads or linings
New brake pads have to be “broken in”, and
therefore only attain optimal friction when the car
has covered several hundred miles or km.
The slightly reduced braking ability must be
compensated for by pressing the brake pedal
harder. This applies whenever the brake pads
and/or brake discs are replaced.

Driving and Driving Safety
Resuming the stored speed – RESUMEfPress the control stalk up (position 4).
Cruise control accelerates/decelerates the
vehicle to the stored speed.
Note on operation
The stored speed should on ly be recalled if traffic
and road conditions are conducive to driving at
that speed.Switching cruise control readiness offf Press button A on the control stalk.
The memory is cleared and the readiness
symbol disappears.
The stored desired speed is cleared when the
ignition is switched off when the vehicle is parked.
Tip on driving
On upward or downward slopes, the set speed
cannot always be maintained by cruise control.
f To obtain sufficient engine braking or a better
rev range, you therefore have to change down
to a lower gear.
Adaptive Cruise ControlAdaptive cruise control maintains any selected
speed between approx. 20–100 mph
(30–160 km/h) when driving on open roads
without you having to use the accelerator.
If a vehicle travelling ahead of you in the same lane
is detected as driving slower than the selected
speed, adaptive cruise control will automatically
maintain a set distance fr om the vehicle in front.
Adaptive cruise control slows your vehicle down if
the distance to the vehicle ahead becomes too
short and accelerates your vehicle if the distance
increases.
Warning!
Risk of accidents in heavy traffic, in city
traffic, on twisting roads or in unfavorable
road conditions (e.g. wintry or wet conditions
or varying road surfaces, etc.).
f Do not use adaptive cruise control under these
conditions.
Adaptive cruise control will not detect
stationary or slowly moving vehicles,
pedestrians, objects on the road, oncoming
vehicles in the same lane or cross traffic.
f You must pay attention to your vehicle’s
position in relation to other objects and
intervene as needed to ensure safe driving.
f Always keep the direction of travel in your field of view.
Radar sensorAdaptive cruise control uses a radar sensor
located in the middle of the front apron.
Maintenance note
fAlways keep the radar sensor clean and free of
ice and snow to ensure tha t it is fully functional.
For car care instructions:
f Please see the chapter “CAR CARE
INSTRUCTIONS” on page 269.

Porsche Doppelkupplung (PDK)Porsche Doppelkupplung (PDK) is a seven-speed
transmission with an “automatic” and a “manual”
selection mode.
In automatic selection mode (selector-lever
position D), gear changing is automatic.
You can change temporarily from automatic to
manual mode using the shift buttons on the
steering wheel.
In manual selection mode (selector-lever
position M ), you change gear using the shift
buttons on the steering wheel or with the PDK
selector lever.
You can change between selector-lever
positions D and M as you wish while driving.
Note
f Take care not to operate the shift buttons on
the steering wheel in advertently in either
automatic or manual mode, thereby triggering
undesired gear changes.
Changing the selector-lever positionThe selector lever is blocked when the ignition is
switched off.
When the ignition is switch ed on, the selector lever
can be moved from position P and N only when
the release button is pressed, and when the brake
pedal is pressed.
Release button
The release button ( arrow) in the selector lever
prevents the gear from being changed
unintentionally.
The release button must be pressed when shifting
to position R or P.
StartingThe engine can only be started using the car key
if the brake pedal is pressed and the selector lever
is in position P or N.Driving offf Only select the desired position for driving off
(D, M or R) when the engine is idling and the
brake pedal is pressed.
f Since the vehicle crawls when in gear,
do not release the brake until you are ready
to drive off.
Driving off on hills
The Drive-Off Assistant assists the driver when
driving off on hills. The vehicle is held on the slope
when the driver changes from the brake pedal to
the accelerator to facilitate driving off immediately
after the brake is released.
f Please see the chapter “HOLD FUNCTION:
DRIVE-OFF ASSISTANT AND STANDSTILL
MANAGEMENT” on page 206.

Selector-Lever PositionsP – Parking lockfEngage parking lock only when the vehicle is
stationary.
If selector-lever position P is flashing in the
instrument panel, the parking lock is not
engaged. The vehicle can roll away.
Shift again from selector-lever position R to P.
f Activate the electric parking brake and then
engage the parking lock.
If selector-lever position P is flashing in the
instrument panel, the parking lock is not
engaged. The vehicle can roll away.
Shift again from selector-lever position R to P.
The ignition key can be removed only in selector-
lever position P.R – Reverse gearf Select only if the vehicl e is stationary and the
brake is applied.N – Neutral (idling)Selector-lever position N must be selected for
towing or in car washes, for example.
f Only select the desired position for driving off
(D , M or R) when the engine is idling and the
brake pedal is pressed.
D – Automatic selection modeSelect position D for “normal” driving. The gears
are shifted automatically according to the
accelerator position and speed.
Depending on the way the vehicle is driven
(economical, comfortable or sporty driving style)
and on the resistance (e.g. uphill), the gear-
changing points are shifted towards higher or
lower engine-speed ranges.
The accelerator position, driving speed, engine
speed, longitudinal and lateral acceleration and
the road profile all have an influence on the gear-
changing characteristic.
Unwanted upshifts, e.g. when entering
bends, are prevented by swiftly releasing the
accelerator pedal.
Depending on lateral acceleration, upshifts on
bends are not made until the engine-speed limit
is reached.
When you brake, and depending on the amount of
deceleration, the PDK transmission changes down
earlier.
For subsequent cornering, the right gear is
engaged when pressure is applied to the brakes
before the bend. The bend is taken in the right
gear, and when you accelerate out of the bend you
do not have to change down.
With a sporty driving style, downshifts are already
initiated when the brake pedal is touched lightly.
This further enhances a dynamic driving style. The PDK transmission temporarily changes to the
sportiest gear-changing map, i.e. to the highest
possible gear-changing points, if the accelerator
pedal is pressed quickly. The transmission
accordingly shifts down
immediately by one or
two gears (temporary change-down).
The transmission no longer selects 7th gear
at high driving speeds.
“Sport” and “Sport Plus” Mode “Sport” mode activated:
The PDK transmission switches to a sporty gear-
changing map and shortens the shifting times.
A sporty driving style is recognized more quickly
and the gear-changing speeds are adapted to
driving performance.
Deceleration downshifts are initiated earlier.
Downshifts occur for small decelerations,
even at higher revs.
“Sport Plus” mode activated:
In “Sport Plus” mode, the PDK transmission
changes to a shift program designed for driving
on race circuits. 7th gear is not selected.
The gear-changing performance is enhanced
significantly again compared with “Sport” mode.
f Please see the chapter ““SPORT” AND “SPORT
PLUS” MODE” on page 212.

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.
