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.
9 mph (14 km/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.

Car Telephone and Aftermarket Alarms Important legal and safety information re-
garding the use of cellular telephones
Some states may prohibit the use of cellular tele-
phones while driving a vehicle. Check the laws and
regulations on the use of cellular telephones in the
areas where you drive.
Danger!
Risk of an accident.
Severe personal injury or death can result in
the event of an accident.
Looking away from the road or turning your
attention away from your driving can cause
an accident and serious personal injury or
death.
When using your cellular telephone, you should al-
ways:
fGive full attention to your driving - pull off the
road and park before making or answering a
call if traffic conditions so require; and
fKeep both hands on the steering wheel - use
hands-free operation (if available) - pull off the
road and park before using a hand-held tele-phone.It is essential to observe the instructions of
the telephone manufacturer before putting
the telephone into operation.
Any portable telephone or radio transmitter which
is used in a Porsche must be properly installed in
accordance with the technical requirements of
Porsche.
The transmission power must not exceed
10 W.
The devices must possess a type approval for
your vehicle and have an “e“ symbol.
If you should require equipment with transmission
power values greater than 10 W, please consult
your authorized Porsche dealer for this purpose.
He is familiar with the technical requirements for
installing devices of this kind.
The antennas for all radios and telephones with a
transmitting antenna must be externally mounted.
The improper installation of radios or telephones
or use of a radio or telephone with a transmitting
antenna inside the car may cause the warning
lights to come on.
Improper installation of such equipment can cre-
ate a discharged battery or excessive current
draw from added equipment.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.

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 352.
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 weight of the car-trailer
combination must therefore be reduced by
10% for each increment of 3,280 ft. or
1,000 metres altitude. A fractional increment
counts as the full 1,000 metres. Please take
this into consideration when planning 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
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
circumstances adapt your speed to prevailing
road and driving conditions.
In no event should you exeed a speed of 50 mph
(80 km/h). Towing in 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
fPlease take into consideration that driving with
a trailer places markedly greater stress on all
vehicle components. Expert inspection and
maintenance after every use are indispensable
prerequisites for proper functioning and safety.
