Driving and Driving Safety
“Sport” and “Sport Plus” Mode FunctionThe selectable chassis settings mean that the
vehicle can offer various modes for a sportier
overall setup.
When “Sport” or “Sport Plus” mode is selected, all
the vehicle’s control systems are intentionally
shifted towards greater agility and driving
performance:
– PASM (Porsche Active Suspension Management) is automa tically changed to
“PASM Sport” or “PASM Sport Plus” mode,
resulting in a stiffer suspension setup.
The vehicle switches to Low Level in “PASM
Sport Plus” mode.
f Please see the chapter “PORSCHE ACTIVE
SUSPENSION MANAGEMENT (PASM)” on
page 208.
– Just like PASM, PDCC is switched to the corresponding “Sport” or “Sport Plus” mode,
whereby the rolling movements of the vehicle
are reduced further, depending on the
selected mode.
f Please see the chapter “PORSCHE DYNAMIC
CHASSIS CONTROL (PDCC)” on page 211.
– The PDK transmission switches to a sporty gear-changing map and shortens the gear
shifting times when Sport mode is activated.
Gear changes take place faster. f
Please see the chapter ““SPORT” AND “SPORT
PLUS” MODE” on page 195.
– The electronic accelerator pedal reacts sooner, and the engine is more responsive to
throttle inputs. When Sport mode is switched
on and the vehicle is travelling at a speed of
less than 25 mph (40 km/h), this function is
activated only after the driver has floored the
accelerator pedal or released it briefly.
– The rpm limiter characteristic is “harder”. In other words: the engine is immediately
throttled when the performance limits are
reached (only in manual selection mode on
vehicles with PDK).
– The turbo overboost briefly increases the engine boost pressure in the engine speed
range from 2,500 rpm to approx. 4,000 rpm.
As a result, torque in this speed range is
increased by 70 Nm (52 ftlb.). This
considerably improves acceleration and
flexibility, particularly in the medium engine
speed range. This does not affect the
maximum power. Quickly flooring the
accelerator pedal acti vates turbo overboost
in the engine control system. Overboost has
an effective operating time of approx.
10 seconds. After this time, it can be re-
activated by quickly flooring the accelerator
pedal again. – PSM (Porsche Stability Management) control is
more sporty in “Sport Plus” mode. PSM
interventions are later than in Normal mode.
The driver can maneuver the vehicle with
greater agility at it s performance limits,
without having to dispense with the assistance
of PSM in emergency situations. This helps to
achieve optimal lap times, particularly on race
circuits with a dry road surface.
f Please see the chapter “PORSCHE STABILITY
MANAGEMENT (PSM)” on page 202.
– Adaptive cruise control regulates speed and distance more dynamically.
– The Auto Start Stop function is deactivated.
f Please see the chapter “AUTO START STOP
FUNCTION” on page 169.
– The rear spoiler extends earlier and retracts later (“Sport Plus” mode only).
f Please see the chapter “RETRACTABLE REAR
SPOILER” on page 214.
– The system switches from High Level.
f Please see the chapter “HIGH LEVEL” on
page 209.

switched on.
fPress button .
When the sports exhaust system is switched
on, the indicator light on the button lights up.
Retractable Rear SpoilerThe rear spoiler improves driving stability at high
speeds and reduces fuel consumption at low
speeds.
Vehicles with a turbo engine have an enhanced
rear spoiler with a larger aerodynamically
effective spoiler surface thanks to additional flaps.Automatic modeAutomatic extension and retraction of the rear
spoiler depends on various conditions.

“Sport Plus” mode deactivated
The rear spoiler extends automatically:
– to position A at approx. 55 mph (90 km/h).
– to position B at approx. 130 mph (205 km/h).
The rear spoiler retracts automatically:
–from position B to position A at approx.
110 mph (180 km/h).
–from position A to the end position at
approx. 40 mph (60 km/h).
Additional rear spoiler position on vehicles
without a turbo engine
The rear spoiler also mo ves to an intermediate
position between A and B when extended at
speeds of between appr ox. 100 mph (160 km/h)
and 130 mph (205 km/h) and when retracted at
speeds of between appr ox. 110 mph (180 km/h)
and 90 mph (145 km/h).
“Sport Plus” mode activated
The rear spoiler extends straight to position B at
approx. 55 mph (90 km/h).
The rear spoiler retracts from position B straight
to the end position at approx. 40 mph (60 km/h). If the automatic control system fails, the warning
message “Spoiler failure”
appears on the multi-
function display.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
Warning!
Risk of accidents if the “Spoiler failure”
warning appears. Driving stability will be
adversely affected if th e rear spoiler retracts
or fails to extend. This is due to increased
rear axle lift at higher speeds. The rear axle
will tend to lift, reducing the road holding
characteristics of the car in higher-speed
turns.
f Adapt your driving style and speed to the
changed driving behavior.
f Have the fault corrected.
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.
Manual modeWhen the ignition is on, the rear spoiler can be
extended and retracted manually using the button
in the center console.
When the rear spoiler is in manual mode,
the indicator light on the button lights up.
The rear spoiler does not retract fully in
manual mode.

Working on your vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
f The engine compartment of any motor vehicle
is a potentially hazardou s area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
f O n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
f Ensure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially
cautious of devices such as hot water heaters
which ignite a flame intermittently.
f Before working on any part in the engine
compartment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
f Be alert and cautious around the engine at all
times while it is running. If you have to work on
the engine while it is running, always put the
parking brake on and put the PDK selector
lever in position P or N.
f In particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get caught in the fan, belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The fans can start or continue running as a
function of temperature,
even with the engine
switched off.
Carry out work in these areas only with the
engine off and exercise extreme caution.
f Your Porsche is equipped with an electronic
ignition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise
extreme caution when working on any part of
the engine while the ignition is on or the engine
is running.
f Always support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
Switch off level control of air suspension and
height adjustment.
Please see the chapter “RAISING THE VEHICLE
WITH A LIFTING PLATFORM, TROLLEY JACK
OR STANDARD JACK” on page 290.
f When working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Withdraw ignition keys (switch ignition off in
vehicles that have Porsche Entry & Drive). f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher close at hand.
f Incomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty
coverage.
f Supplies of fluids, e.g. engine oil, washer fluid,
brake fluid or coolant, are hazardous to your
health.
Keep these fluids out of children's reach and
dispose of them in accordance with the
appropriate regulations.
f Some countries require additional tools and
special spare parts to be carried in your
vehicle. Please make enquiries before driving
abroad.

Technical ModificationsfModifications may be carried out on your
vehicle only if approved by Porsche.
This ensures that your Porsche will remain
reliable and safe to drive, and that it will not be
damaged as a result of the modifications.
Your authorized Porsche dealer will be pleased
to advise you.
Safety notes!
f Only use genuine Porsche spare parts for your
vehicle or spare parts of similar quality which
have been manufactured according to the
specifications and production requirements of
Porsche. These parts are available from your
authorized Porsche dealer or a qualified
specialist workshop. Safety-related
accessories should only be used if they are
from the Porsche Tequipment range or are
tested and approved by Porsche. Your
authorized Porsche dealer will be pleased to
advise you and answer any questions you may
have.
However, the use of other parts or
accessories may adversel y affect the safety
of your vehicle, and Porsche can take no
responsibility for any loss or damage caused
by their use.
Even if the supplier of other accessories or
parts is a recognized supplier, the safety of
your vehicle may still be affected if such items
are installed.
Due to the large variety of products offered in the accessory market, it is not possible for
Porsche to inspect and approve every one.
f In addition, please note that the use of
replacement parts that are not genuine
Porsche parts or approved parts, or the use of
accessories not approved by Porsche may
also detrimentally affect your vehicle warranty.
f Check your vehicle regularly for signs of
damage. Damaged or missing aerodynamic
components, such as spoilers or underbody
panels, impair vehicle handling and must
therefore be replaced immediately.
Radiator fanFor information on radiator fans:
fPlease see the chapter “RADIATOR FANS” on
page 258.
Warning!
Danger of injury. After the ignition is
switched off, the engine compartment and
coolant temperatures are monitored for
approx. 30 minutes. During this period, and
depending on temperature, the radiator fan
may continue to run or start to run.
f Carry out work in these areas only with the engine off and exercise extreme caution.
