Parking AidsParkAssistParkAssist provides a visual and acoustic indica-
tion to the driver of the distance between the
vehicle and a large obstacle.
ParkAssist is switched on automatically when the
engine is started and remains active up to a speed
of approx. 9 mph (14 km/h).
ParkAssist is switched off automatically at high
speed. ParkAssist is switched on again auto-
matically when the speed drops below approx.
9mph (14km/h).
The selector lever position determines activation
levels for ParkAssist and the corresponding area
that is monitored.
Selector lever position:
–P – ParkAssist is not activated.
–R, N – ParkAssist is activated for the front and
rear areas.
–D, M – ParkAssist is activated for the front ar-
ea.Gearshift lever position:
–R– ParkAssist is activated for the front and
rear areas.
–In all other gearshift positions – ParkAssist
is activated for the front area.
Note
On vehicles with manual transmission, the parking
assistant is not switched on in the rear area if the
vehicle rolls backward without reverse gear enga-
ged.
Danger!
Risk of serious personal injury or death.
ParkAssist cannot detect small objects such
as children and pets.
Even when using ParkAssist, the driver is still
responsible for taking due care when park-
ing and when assessing obstacles.

Controls, Safety, Instruments If aftermarket systems are installed by non-dealer-
ship technicians or outside the selling dealer,
problems may result. Installation of aftermarket
equipment is not covered under the New Car War-
ranty.
fConsult your authorized Porsche dealer about
the installation of non Porsche approved equip-
ment.
Reception quality
The reception quality of your car telephone will
change constantly when you are driving. Interfer-
ence caused by buildings, landscape and weather
is unavoidable. It may become particularly difficult
to hear when using the hands-free function due to
external noise such as engine and wind noise.
Automatic car-wash
fUnscrew external antennas before using an au-
tomatic car-wash.
Porsche Communication
Management (PCM)
Warning!
There is a danger of accident if you set or
operate the on-board computer, radio, navi-
gation system, telephone or other equipment
when driving.
This could distract you from the traffic and
cause you to lose control of the vehicle re-
sulting in serious personal injury or death.
fOperate the components while driving only if
the traffic situation allows you to do so safely.
fCarry out any complicated operating or setting
procedures only with the vehicle stationary
fIf it is necessary to operate these components
while the vehicle is in motion, use the function keys on the multi-functional steering wheel.
fRefer to the separate operating instructions
before putting the PCM into operation.
When put into operation for the first time, a dis-
tance of approx. 3 miles (5 km) must be driven in
order for the navigation system to complete the
process of fine calibration. The same applies
when the tires are changed (e.g. summer/winter
tires) or new tires fitted. Full location accuracy is
not yet achieved during the fine-calibration pro-
cess.If the vehicle has been transported (e.g. ferry, car
train), the system may take a few minutes after be-
ing switched on before it determines the current
location.
Serious tire slip (e.g. spinning wheels on snow)
may result in temporarily inaccurate navigation.
When the battery has been disconnected, it may
take up to 15 minutes before the navigation
system is operational once more.
Satellite radioYou must have the satellite radio activated before
you can put it into operation. You will need a con-
tract with a provider in order to use this radio.
fRefer to the separate radio operating instruc-
tions before putting into operation.

Towing a trailer
Warning!
Driving with a trailer
fAlways observe the permissible towing capac-
ity, vertical coupling load and rear-axle load.
Please observe the chapter “WEIGHTS” on
Page 363.
fWhen connected, the trailer must always be
horizontal behind the towing vehicle. If neces-
sary, use a trailer with an adjustable drawbar.
fWhen the vehicle is driven in the mountains, the
engine output decreases as altitude increases.
The maximum weights stated are the values at
sea level. The total permissable weight of the
car-trailer combination must therefore be re-
duced by 10% for each increment of 3,280 ft.
(1,000 meters) altitude. A fractional increment
counts as the full 3,280 ft. (1,000 meters).
Please take this into consideration when plan-
ning your route.Distributing the load
fDistribute the load in the trailer so that heavy
objects are as close to the axle as possible.
Always safeguard all objects against slipping
and tie them down securely.
fYou should make the best possible use of the
trailer coupling's rated vertical coupling load
when loading the trailer, but never exceed it.
Tire pressure
fSelect the vehicle tire pressure for full load
when towing a trailer.
fPlease observe the chapter “Tire pressure ta-
bles”.
fCheck the tire pressure of the trailer's wheels
according to the manufacturer's instructions.Door mirrors
fIf the width of the trailer obstructs your view of
the traffic behind the trailer, you must have ad-
ditional door mirrors fitted.
Headlights, lights
fAlways check the headlight adjustment before
driving with a trailer.
If necessary, correct with the headlight beam
adjustment function.
fCheck whether the plug of the trailer is
plugged into the towing vehicle and whether all
lights function.

Driving with a trailer
When towing a trailer you must under all circum-
stances adapt your speed to prevailing road and
driving conditions. Never exeed a speed of
50 mph (80 km/h). Towing at excessive speed
can result in loss of control.
fCarefully and gradually familiarize yourself with
the handling and braking behavior of the car-
trailer combination.
fDo not drive with the towing vehicle empty and
the trailer loaded.
If this unfavorable combination is unavoidable,
please drive especially slowly.
fBear in mind the different vehicle handling and
size in situations such as braking, parking,
cornering and overtaking, etc.
fThe driving stability of the car-trailer combina-
tion worsens as the speed increases. There-
fore, drive especially slowly on downhill
stretches and in the case of unfavorable road
and weather conditions (such as wind).
fDrive in an appropriately low gear on downhill
stretches in order to make use of the engine
braking effect.fSlow down immediately if the trailer starts to
sway. Do not countersteer; brake if necessary.
Never attempt to straighten out the car-trailer
combination by accelerating.
fActivate Low Range when moving off on steep
slopes.
fUnder no circumstances may people, animals
or objects be in the space between the trailer
and the towing vehicle when the vehicle is
moving.
fWhen reversing, bear in mind that ParkAssist is
not active.
Maintenance note
Please take into consideration that driving with a
trailer places markedly greater stress on all vehi-
cle components. Expert inspection and mainte-
nance after every use are indispensable prerequi-
sites for proper functioning and safety.

Warning!
Risk of accident.
fDo not obstruct the pedal travel with floor mats or other objects.
Floor mats of the correct size and with the
appropriate fasteners are available from your
authorized Porsche dealer.The positions of the gears are shown on the shift
diagram on the gearshift lever.
fWhen shifting gears, always ensure that the
clutch pedal is fully depressed and the gear
has fully engaged.
fSelect reverse only when vehicle is stationary.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
When reverse gear is selected and the ignition is
on, the reversing lights are lit.
Permitted engine speedfYou should change into a higher gear before
the needle reaches the red mark on the
tachometer, or ease off the accelerator.
If the red zone is reached during acceleration, fuel
feed is interrupted.
Caution!
Risk of engine damage (overrevving) when
shifting down to a lower gear.
fTake care not to exceed the maximum permit-ted engine speed when down-shifting.
