2010 PORSCHE CAYENNE towing capacity

Trailer Hitch
231
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
maximum total weight of vehicle, passengers,
luggage, hitch, trailer tongue load and optional
equipment.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 see the chapter “TIRES, RIMS, TRACKS”
on Page 350.
The load capacity coefficient (e.g. “106”) is a
minimum requirement. For more information:
fPlease see the chapter “INSCRIPTION ON
RADIAL TIRE” on Page 290.
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
capacity 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 permissible inflation pres-
sure.
The cargo capacity is the permissible weight of
cargo, the subtracted 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 loss of control, damage to the vehicle
and serious personal injury or death.
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 vehicle warranty.

Tr a i l e r H i t c h
Example for determining the combined weight of occu-
pants and cargoVehicle Load CapacityfThe combined weight of occupants and cargo
should never exceed the weight shown on the
tire plate in the vehicle.
Please see the chapter “TIRE PRESSURE
PLATE” on Page 348.
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
vehicle.
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
cargo 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
reduces the available cargo and luggage load
capacity of your vehicle.

Tr a i l e r H i t c h
Towing a trailer
Warning!
Driving with a trailer
fAlways see the permissible towing capacity,
vertical coupling load and rear-axle load.
Please see the chapter “WEIGHTS” on
Page 356.
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 see the chapter “TIRE PRESSURES,
COLD (68 °F/20 °C)” on Page 354.
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
additional 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. Towing at excessive speed can
result in loss of control. Observe country-specific
laws for driving with trailers.
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.
fAlways see the permissible towing capacity,
vertical coupling load and rear-axle load.
Please see the chapter “WEIGHTS” on
Page 356.
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.

Minor Repairs
323
Emergency Starting with Jumper
CablesIf the battery is discharged, e.g. in winter or after
the car has been parked for a long time, the bat-
tery of another car can be used for starting with
the help of jumper cables.
Make sure the voltage of both batteries is the
same.
The capacity (Ampere hours, Ah) of the booster
battery must not be substantially less than that of
the discharged battery.The discharged battery
must be correctly connected to the vehicle's elec-
trical system.
fPlease see the chapter “BATTERY” on
Page 320.
Note
Do not try to start the car by pushing or towing.
Damage to the catalytic converters and other
components of the car may result.
Danger!
Risk of short circuit, damage and explosion,
resulting in serious personal injury or death.
fUse only jumper cables of adequate diameter
cross-section and fitted with completely
insulated alligator clips.
fFollow all warnings and instructions of the
jumper cable manufacturer.
fWhen connecting jumper cables, make sure
that they cannot get caught in any moving
parts in the engine compartment.
The jumper cables must be long enough so
that neither vehicles nor cables touch another.
fThe vehicles must not be in contact, otherwise
current might flow as soon as the positive
terminals are connected.
fThe cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
fCarefully ensure that tools or conductive jewe-
lery (rings, chains, watch straps) do not come
into contact with the positive jumper cable or
the positive battery post.
fImproper hook-up of jumper cables can ruin
the alternator.
Danger of caustic burns.
fDo not lean over the battery.Danger of gas explosion.
fImproper use of booster battery to start a
vehicle may cause an explosion, resulting in
serious personal injury or death.
fKeep sources of ignition away from the
battery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
fA discharged battery can freeze even at
14 °F (−10 °C). Before connecting jumper
cables, a frozen battery must be thawed out.
