Six ultrasound sensors in the front and rear
bumpers measure the distance to the closest ob-
stacle.
– Range of outer sensors
(front and rear):
approx. 24 in. (60 cm)
– Range of front middle sensors (arrow):
approx. 48 in. (120 cm)
Rear ultrasound sensors– Range of rear middle sensors (arrow)
(only in vehicles without spare wheel bracket):
approx. 59 in. (150 cm)
– Range of rear middle sensors
(only in vehicles with spare wheel bracket):
approx. 48 in. (120 cm)
Obstacles cannot be detected in the "blind" sensor
area (above and below the sensors).Maintenance note
fThe sensors must always be kept free of dust,
ice and snow in order to ensure that they are
fully functional.
fDo not damage sensors by abrasion or
scratching.
fMaintain sufficient distance when cleaning with
steam-jet units.
The sensors will be damaged if the pressure is
too high.
Note on operation
The rear ultrasound sensors may not function
correctly if tires that have not been recommended
by Porsche are fitted on the spare wheel bracket.
If the spare wheel bracket is open, this may impair
the function of the rear ultrasound sensors.
In vehicles that have air suspension with level
control and height adjustment, the system may
not recognise obstacles near the ground at terrain
level or special terrain level.

Loading InformationDefinitionsThe towing capacity (gross weight of the trailer)
is the sum of the trailer's empty weight and the
weight of the load.
The vertical coupling load is the weight that the
trailer drawbar exerts on the trailer coupling of the
vehicle.
The rear-axle load is the vehicle weight on the
rear axle plus the weight of the transported load
and the vertical coupling load of the trailer.
The gross weight of the vehicle and trailer is
the sum of the weight of the towing vehicle and the
weight of the trailer.
The Curb weight - actual weight of your vehicle -
vehicle weight including standard and optional
equipment, fluids, emergency tools, and spare tire
assembly. This weight does not include passen-
gers and cargo.
The Gross Vehicle Weight is sum of the curb
weight and the weight of passengers and cargo
combined.
The Gross Vehicle Weight Rating is the maxi-
mum total weight of vehicle, passengers, lug-
gage, hitch, trailer tongue load and optional equip-
ment.The Gross Axle Weight Rating is the maximum
load limit for the front or the rear axle. This infor-
mation is located on the safety comliance sticker
located in the driver’s side door jamb.
For determining the compatibility of the tire and
vehicle load capabilities:
fPlease observe the chapter “TIRES, RIMS,
TRACKS” on Page 358.
The load capacity coefficient (e.g. “106”) is a mi-
nimum requirement.
The Gross Combined Weight Rating is the
maximum total weight rating of vehicle, passen-
gers, cargo and trailer.
The Vehicle Capacity Weight - Load Limit - is
the maximum total weight limit specified of the
load (passengers and cargo) for the vehicle. This
is the maximum weight of passengers and cargo
that can be loaded into the vehicle. This informa-
tion can be found on the tire pressure plate.
If a trailer is being towed, the trailer tongue weight
must be included as part of the cargo load.
The maximum loaded vehicle weight is the
sum of curb weight, accessory weight, vehicle ca-
pacity weight and production options weight.
The load rating is the maximum load that a tire
is rated to carry for a given inflation pressure.
The maximum load rating is the load rating for
a tire at the maximum permissble inflation pres-
sure.The cargo capacity is the permissible weight of
cargo, the substracted weight of passengers from
the load limit.
fNever exceed the permissible limits.
Danger!
Risk of personal injury or death.
Injuries are much more likely in an accident
if persons ride in the cargo area.
fPersons must ride only on the seats provided
for this purpose.
fMake sure that everybody fastens their safety
belts.
Risk of personal injury, loss of control and
damage to vehicle.
fNever exceed the specified axle loads. Over-
loading can shorten the service life of the tires
and car, as well as lead to dangerous vehicle
reactions and long braking distances. Damage
due to overloading is not covered by the vehic-le warranty.

Example for determining the combined weight of occup-
ants and cargoVehicle Load CapacityfThe combined weight of occupants and cargo
should never exceed the weight shown on the
tire plate in the vehicle.
Please observe the chapter “TIRE PRESSURE
PLATE” on Page 281.
fNever exceed the number of passengers
shown on the tire pressure plate in the vehicle.Determining the combined weight of
occupants and cargo:
fAdd the weight of all occupants and then add
the total luggage weight (figure).
Steps for determining correct load limit
1. Locate the statement "The combined weight of
occupants and cargo should never exceed XXX
pounds" on your vehicle’s placard (depending
on the date of manufacture)
2. Determine the combined weight of the driver
and passengers that will be riding in your vehic-
le.
3. Subtract the combined weight of the driver and
passengers from XXX kilograms or XXX
pounds.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the "XXX" amount equals 1400
lbs. and there will be five - 150 lb passengers
in your vehicle, the amount of available cargo
and luggage load capacity is 650 lbs. (1400 -
750 (5 x 150) = 650 lbs.)
5. Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available car-
go and luggage load capacity calculated in
Step 4.
6. If your vehicle will be towing a trailer, load from
your trailer will be transferred to your vehicle.
Consult this manual to determine how this re-
duces the available cargo and luggage load ca-
pacity of your vehicle.

Stowing load in the vehicle
Warning!
Danger of injury.
An unsecured or incorrectly positioned cargo
can slip out of place or endanger the vehicle
occupants during braking, direction changes
or in accidents.
Never transport objects which are not se-
cured.
fAlways transport cargo in the cargo area, nev-
er in the passenger compartment (e.g. on or in
front of the seats).
fSupport the cargo on the seat backrests when-
ever possible. Always lock the backrests into
place.
fPlace the cargo behind unoccupied seats
whenever possible.
fStow heavy objects as close to the front of the
cargo area as possible, with lightweight ob-
jects behind them.
fThe cargo must never project over the top
edge of the seat backrest.
fAlways protect the passenger compartment
with a luggage safety net and a luggage
compartment cover.
Do not drive with objects on top of the luggage
compartment cover.fIf the rear seats are not occupied, the back-
rests can be additionally secured with the safe-
ty belts. Simply cross the outer safety belts
and insert each into the opposite buckle.
fMake sure that the cargo cannot damage the
heating filaments of the rear window and the
TV antenna of the side window.
Luggage net
fLuggage must be stowed completely covered
by the luggage net.
The luggage net can prevent only lightweight
objects from slipping.
Tie-down belts
fDo not use elastic belts or straps to tie down
cargo.
fDo not place belts and straps over sharp edg-
es.
fObserve the directions for use and information
for the tie-down equipment.
fUse only belts with a tear strength of at least
1543 lbs. (700 kg) and a maximum width of
1in. (25mm).
fCross the belts over the load.Driving
fThe car's handling changes depending on the
vehicle loading. Adapt your driving style to the
changed driving behavior.
fDo not exceed the maximum gross weight and
the axle load.
fPlease observe the chapter “WEIGHTS” on
Page 363.
fNever drive with the rear window or rear lid
open.
Exhaust gases can enter the passenger
compartment.
fAdapt the tire pressure to the load.
fPlease observe the chapter “LOAD” on
Page 93.
fPlease observe the chapter “TIRE PRESSU-
RES, COLD” on Page 361.

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.
