WARNING MESSAGES” on page 152.
BrakesfMake it a habit to chec k the operation of your
brakes before driving.
Keep in mind that the braking distance increases
very rapidly as the speed increases. At 60 mph
(100 km/h), for example, it is not twice but four
times longer than 30 mph (50 km/h). Tire traction
is also less effective when the roads are wet or
slippery.
f Therefore, always maintain a safe distance
from the car in front of you.Vehicles without Porsche Ceramic
Composite Brake (PCCB)Even though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to
corrode if your car is parked for an extended
period. The brakes will tend to “rub” as a result.
The nature, extent and effects of corrosion
depend on the amount of time the vehicle was
parked, whether road salt or grit was spread and
whether grease-dissolving agents were used in
car washes.
If the braking comfort is noticeably impaired, we
recommend having the brake system checked by
experts at an authorized Porsche dealer.
Brake system functionYour Porsche is equipped with a power assisted
hydraulic dual circuit brake system with disc
brakes at the front and rear.
Both circuits function independently. One brake
circuit operates the front left and rear right wheel
and the other operates the front right and rear left
wheel.
If one brake circuit has failed, the other will still
operate. However, you will notice an increased
pedal travel when you apply the brakes. Failure of
one brake circuit will cause the stopping distance
to increase.
Warning!
Risk of an accident, resulting in serious
personal injury or death.
In the unlikely event of hydraulic failure of
one brake circuit:
f Push the brake pedal down firmly and hold it in
that position. A mechanical linkage activates
the second circuit, and you will be able to bring
the vehicle to a stop.
f After bringing your vehicle to a complete stop,
avoid driving the vehicle and instead have it
towed to the nearest authorized Porsche dealer for repair.

StoppingfFor a brief stop, e.g. at traffic lights, leave the
selector lever in drive position and hold the
vehicle with the brake pedal.
f Do not hold the vehicle on a slope using the
accelerator. Use the brake pedal or the
electric parking brake instead.
f Before leaving the vehicle, always apply the
electric parking brake and move the selector
lever to position P.Parkingf Go easy on the accelerator!
f When parking or maneuvering in a small
space, control the speed by careful use of
the footbrake.Driving in winterIn wintry road conditions, it is advisable to take
steep inclines in manual mode. This prevents gear
changes occurring that could cause wheel spin.Tow-starting, towingfPlease see the chapter “TOWING” on
page 316.
Reduced driving programIf there is a fault in the transmission
– Depending on priority, either the “Gearbox
emergency operation” warning in yellow or red
or the warning “Gearbox temperature too high”
will appear on the multi-function display.
“Gearbox emergency operation” warning in
yellow
Effects:
– Restricted gearshift comfort, reverse gear may not function.
Action required:
f Have the fault corrected immediately.
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. “Gearbox emergency operation” warning in red
Effect:
– Vehicle can be driven
only until it comes to
astop.
Action required:
f It is not possible to continue driving. Stop the
vehicle immediately in a suitable place. Have
the vehicle towed to a qualified specialist
workshop.
f Please see the chapter “TOWING” on
page 316.
Warning “Gearbox temperature too high”
–Effects: “Warning jerks” can be fe lt when driving off and
the engine power may be restricted.
Action required:
Do not hold the vehicle with the accelerator on
a hill, for example. Hold the vehicle with the
brake. Reduce engine load. Stop the vehicle in
a suitable place if possib le. Allow the engine to
run in selector-lever position P or N until the
warning disappears.

Advantages of PSM
– Best possible traction and lane-holding ability
in all driving situations – even on road surfaces
with varying friction.
– The system compensates for undesired vehicle reactions (Ferraria effect) when the
driver releases the accelerator pedal or brakes
on bends. This compensation functions up to
the maximum lateral acceleration.
– PSM actively stabilises the vehicle if necessary during dynamic driving maneuvers (e.g. rapid
steering movements, during lane changes, or
on alternating bends).
– Improved braking stability on bends and on different or varying road surfaces.
– Improved brake function and shorter stopping distance in the event of emergency braking. Readiness for operation
PSM is switched on automatically every time you
start the engine.
Function
Sensors at the wheels, brakes, steering system
and engine continuously measure:
–Speed
– Direction of travel (steering angle)
– Lateral acceleration
– Axial acceleration
– Rate of turn about the vertical axis
PSM uses these values to determine the direction
of travel desired by the driver.
PSM intervenes and corrects the course if the
actual direction of motion deviates from the
desired course (steering-wheel position):
It brakes individual wheels as required.
If necessary, PSM also influences the engine
power or the gear-changing characteristic of
Porsche Doppelkupplung (PDK) in order to
stabilise the vehicle. The events below inform the driver of PSM control
operations and warn him to adapt his driving style
to the road conditions:
– PSM warning light on the instrument panel
flashes.
– Hydraulic noises can be heard.
– The vehicle decelerates and steering-wheel forces are altered as PSM controls the brakes.
– Reduced engine power.
– The brake pedal pulsates and its position is changed during braking.
In order to achieve full vehicle deceleration,
foot pressure must be increased after the
brake pedal has begun vibrating.
Examples of PSM control operations
– If the “front wheels of the vehicle drift” on
a bend, the engine power is reduced and the
rear wheel on the inside of the bend is braked
if necessary.
– If the rear of the vehicle swings out on a bend, the front wheel on the outside of the bend is
braked.

Porsche Active Suspension
Management (PASM) with Air
Suspension and Level ControlPASM with air suspension is an active shock
absorber adjustment and ride height balancing
system. The adjustable damper system selects
the appropriate damping level for each wheel
according to the driving situation and driving
conditions. The level control system automatically
balances load changes and maintains a constant
ride height. Driving safety , agility and comfort are
optimised.
Three different chassis setups can be selected at
the push of a button:
– “PASM Comfort”
– “PASM Sport”
– “PASM Sport Plus”
Comfort mode ensures comfortable chassis
tuning.
The “PASM Sport” chassis setup offers very
sporty shock absorber tuning.
“PASM Sport Plus” mode offers particularly sporty
shock absorber tuning (e.g. for driving on the race
circuit). The vehicle is also lowered by
approx. 1 in. (25 mm) compared with the normal
level and the spring rate is increased.
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 mode1. Switch on ignition.
2. Start the engine.
3. Press button (repeatedly).
On the button:
– No indicator light come s on when you select
“PASM Comfort” (default setting).
– One indicator light comes on when you select “PASM Sport”.
– Two indicator lights come on when you select
“PASM Sport Plus”. In addition, the selected chassis setup is shown on
the multi-function display in the instrument panel
for approx. 4 seconds.
Note
The mode cannot be changed if a door or the
tailgate is opened or when the engine is switched
off.
When the vehicle is stopped, the ride height may
be adjusted automatically
in order to balance the
vehicle load.
High LevelThe level control system al lows you to raise the
vehicle in maneuvering mode by approx. 0.8 in.
(20 mm) compared with the normal level in order
to drive over curbs and ramps.
High Level can only be selected manually and at
speeds of less than approx. 20 mph (30 km/h).
Note
High Level must not be us ed on public roads since
the prescribed installation height of the reflectors
can be exceeded in High Level.

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

f Exercise extreme caution when working in the engine compartment.
Topping Up Engine OilPorsche recommends .1) Generally, you can find details on the
manufacturer approvals on the oil containers or as
a notice displayed by the retailer.
The current approval status is also available from
your authorized Porsche dealer.2) SAE viscosity class - Example: SAE 0W - 40
Specification 0W = Viscos ity specification for low
temperatures (winter).
Specification 40 = Viscosity specification for high
temperatures.3) For all temperature ranges.4) For the temperature range over –13 °F
(–25 °C).
Always observe the following points:
– Use engine oils approved by Porsche only. This is a precondition for optimum and
problem-free driving.
– Regular oil changes are part of servicing. It is important that the service intervals,
particularly the oil change intervals, are
observed in accordance with the specifications
in the “Maintenance” booklet. – Oils approved by Pors
che can be mixed with
each other.
– Porsche engines are designed so that no oil additives may be used.
– A label is located in the engine compartment,
which provides you with information on suitable
oil for your engine.
Your authorized Porsche dealer will be pleased to
advise you.
Caution!
Fire hazard if engine oil comes into contact
with hot engine parts.
Risk of damage if engine oil comes into
contact with the drive belt.

Maintenance and Car Care
Fuel EconomyFuel economy will vary depending on where,
when and how you drive, optional equipment
installed, and the general condition of your
car.
A car tuned to specifications and correctly
maintained, will help you to achieve optimal
fuel economy.
fHave your vehicle tuned to specifications. Air
cleaner should be dirt free to allow proper
engine “breathing”.
Battery should be fully charged.
Wheels should be properly aligned.
Tires should be inflated to the correct
pressure.
f Always monitor your fuel consumption.
f Drive smoothly, avoid abrupt changes in speed
as much as possible.
f Avoid jack rabbit starts and sudden stops.
f Do not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
f Prolonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.
f Switch off the engine if stationary for longer
periods.
f Any additional weight carried in the vehicle
reduces fuel economy. Always keep cargo to
a minimum and remove all unnecessary items. f
Organize your trips to take in several errands
in one trip.
f All electrical accessories contribute to
increased fuel consumption.
f Only switch on the air conditioning when
necessary.
f Do not drive with the Ro of Transport System
mounted unless you need it.
The EPA estimated miles per gallon (mpg) is
to be used for comparison purposes, actual
mileage may be different from the estimated
mpg, depending on your driving speed,
weather conditions and trip length. Your
actual highway mileage may be less than the
estimated mpg.
f Please observe all local and national speed
limits.
Operating Your Porsche in other
CountriesGovernment regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards.
Therefore, cars built for the U.S. and Canada differ
from vehicles sold in other countries.
If you plan to take your Porsche outside the
continental limits of the United States or Canada,
there is the possibility that
– unleaded fuel may not be available;
– unleaded fuel may have a considerably lower
octane rating. Excessi ve engine knock and
serious damage to both engine and catalytic
converters could result;
– service may be inadequate due to lack of proper service facilities, tools or diagnostic
equipment;
– replacement parts may not be available or very difficult to get.
Porsche cannot be responsible for the
mechanical damage that could result
because of inadequate fuel, service or parts
availability.
If you purchased your Porsche abroad and want to
bring it back home, be sure to find out about
shipping and forwarding requirements, as well as
current import and customs regulations.
