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.

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.

Porsche Drive-Off Assistant –
Moving-off assistant on vehicles with
manual transmissionThe Porsche Drive-Off Assistant enables the driver
to move off on upward slopes. The vehicle must
have sufficient road contact to use this feature.
The Porsche Drive-Off Assistant is available for
slopes starting at approximately 5%.
fPlease observe the chapter “TRAILER
COUPLING” on Page 194.
Danger!
Risk of accident.
When moving off on a slippery surface (e.g.,
on icy or loose surfaces), assistance by the
Porsche Drive-Off Assistant is no longer
assured. In this case, the vehicle could slip.
The limits set by the physics of driving cannot
be overcome, even with the Porsche Drive-
Off Assistant. The responsibility for moving
off on upward slopes is still the driver's,
despite the Porsche Drive-Off Assistant.
fAlways adjust your driving style to the driving
conditions and vehicle load, use the footbrake if necessary.Moving off with Porsche Drive-Off Assistant
1. Hold the vehicle securely with footbrake or
parking brake on the slope.
The engine must be running.
2. Fully depress the clutch pedal.
3. Engage one of the gears used to ascend in the
direction of travel (1st gear or reverse).
4. While keeping the clutch pedal depressed,
release the footbrake or foot-operated parking
brake.
The vehicle is held on the slope.
5. Move off as usual.Note on operation
The Porsche Drive-Off Assistant ceases to
function:
– by shifting to neutral.
– when changing gears.
– by stopping or “stalling” the engine.
Danger!
Risk of accident.
If the Porsche Drive-Off Assistant ceases to
function, the vehicle will no longer be held on
a slope.
fHold the vehicle with the footbrake.
