Driving and Driving Safety
f
Do not warm up the engine when stationary.
Drive off immediately. Avoid high revs and full
throttle until the engine has reached operating
temperature.
f If the vehicle battery power is too weak, the
engine can be started with jump leads.
For information on jump-lead starting:
f Please see the chapter “EXTERNAL POWER
SUPPLY, JUMP-LEAD STARTING” on
page 306.
Note on operation
To ensure a good battery charge condition,
thereby ensuring that the battery will start the
engine, all electrical loads that are not required
should be switched off when the ignition is
switched on and when engine revs are low
(in traffic jams, in city traffic or in queues).
Stoppingf Only remove the ignition key when the vehicle
is stationary.
f Only switch the ignition off when the vehicle is
stationary, as there is no power steering and
brake booster assistance when the engine is
switched off.
f When leaving the vehicle, always remove the
ignition key, apply the electric parking brake
and engage selector-lever position P .
The control unit always remains in the ignition
lock on vehicles with Porsche Entry & Drive .
Warning!
Danger of injury. Hot engine compartment
components can burn skin on contact.
f Before working on any part in the engine
compartment, turn the engine off and let it cool
down sufficiently.
Risk of burn injury when standing near or
coming into contact with the exhaust pipe.
The exhaust pipe is hot wh en the vehicle is running
and remains hot for some time after the vehicle is
turned off. f
To prevent injury, make a point of noting where
your vehicle’s exhaust pipe is, avoid placing
your legs near the exhaust pipe when loading
and unloading cargo in the rear, and closely
supervise children around the vehicle during
time when the exhaust pipe could be hot.
A hot exhaust pipe can cause painful skin
burns.
Radiator fanFor information on radiator fans:
f Please 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,
always anticipating that the fan blade could suddenly start to run.

when driver’s intention to drive off is
detectedIf the engine is running, the driver’s door is closed
and the driver’s seat belt is fastened, it is still
possible to drive off even though the parking
brake is on. The electric parking brake detects
the driver’s intention to drive off and releases
automatically. The warning light on the instrument
panel goes out.
If the driver’s door is not closed or the driver’s
seat belt is not fastened, the electric parking
brake will not be released automatically when the
driver attempts to drive off.
The message “Release electric parking brake”
appears on the multi-function display in the
instrument panel. The brake warning light on the
instrument panel and the indicator light on the
switch start to flash.

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.

Warning!
f Do not obstruct the pedal travel with floor mats
or other objects.
The brake booster is ready for operation only
while the engine is running.
If the engine is switched off or there is a defect in
the brake booster, much greater force has to be
applied to the pedal when braking.
f Vehicles with defective brakes must not
be towed and must be transported on a flat
bed.
For information on towing and tow-starting:
f Please see the chapter “TOWING” on
page 316.
In heavy rain, while driving through water or after
leaving a car wash, the braking action may be
delayed and increased pressure may be required.
f For this reason, keep further back from the
vehicle in front and “dry” the brakes by
applying them at interval s. Make sure that the
traffic behind you is not affected. After a long drive over salted or gritted roads,
a coating may form on the brake discs and pads
that significantly reduces
friction and therefore
also braking effect.
f Even though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to
corrode if your vehicle 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 (not on vehicles with
Porsche Ceramic Composite Brake).
To prevent corrosion of the brake discs,
“brake them dry” before parking the vehicle
(not on vehicles with Porsche Ceramic
Composite Brake).
If braking comfort is no ticeably impaired, we
recommend that you have the brake system
checked by an authorized Porsche dealer. f
To relieve the brake system on downhill
stretches, change down to a lower gear in
good time (engine braking).
If engine braking is insufficient on steep
stretches, operate the footbrake at intervals.
Avoid continuous braking as it overheats the
brakes and reduces the braking effect.
For information on brake fluid and checking the
brake fluid level:
f Please see the chapter “BRAKE FLUID” on
page 258.

Driving and Driving Safety
Exceptions for adaptive cruise control
Adaptive cruise control is
not available in the
following situations:
– If the ignition is switched off.
– When PSM is off.
– If the driver’s door is opened and the driver’s seat belt is not fastened.
– When parking or maneuvering in very tight spaces.
– If the PDK selector lever is at position N, R or
P .
– On upward or downward slopes of more than 20 %.
– When the electric parking brake is activated.
If one of these exception situations occurs when
adaptive cruise control is switched on, adaptive
cruise control will be switched off.
A message to this effect will appear on the
multi-function display. Messages on the multi-function display
If adaptive cruise control was deactivated
automatically or if an action cannot be performed,
a message to this effect in blue appears on the
multi-function display.
–“
ACC not available! ”
Adaptive cruise control is not available,
e.g. when maneuvering.
–“ ABS/PSM intervention!”
Adaptive cruise control was deactivated
because ABS or PSM intervened as a control
mechanism.
–“ Electric parking brake! ”
Adaptive cruise control was deactivated
because the electric parking brake was
activated.
–“ Selector position!”
Adaptive cruise control was deactivated
because the PDK select or lever is not in
position D or manual position M.
–“ Impossible while parked ”
The required action is not possible because
your vehicle is stationary, e.g. when setting
a desired speed.
–“ Speed! ”
Adaptive cruise control was deactivated
because the rpm limit of the engine was
reached in manual position M of the PDK
selector lever. –“
Gradient too steep! ”
The desired distance or the desired speed
cannot be set because the gradient on the
road is too steep.
–“ Stationary object ”
The action is not possi ble because a stationary
object was detected ahead.
–“ PSM off! ”
Adaptive cruise control is not available
because PSM was switched off.
For information on Porsche Stability
Management (PSM):
f Please see the chapter “PORSCHE STABILITY
MANAGEMENT (PSM)” on page 202.

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.

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.

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.
