Loading InformationDefinitionsThe Curb weight - actual weight of your vehicle -
vehicle weight including standard and optional
equipment, fluids and emergency tools. This
weight does not include passengers 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, luggage
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 compliance 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 911 CARRERA, 911 CARRERA S” on
Page 288.
The load capacity coefficient (e.g. “100”) is a min-
imum requirement.The Gross Combined Weight Rating is the
maximum total weight rating of vehicle, passen-
gers and cargo.
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.
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, 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 vehi-cle warranty.

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 observe the chapter “TIRE PRESSURE
PLATE” on Page 285.
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 vehi-
cle.
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.

A- Filler bottle
B- Filler hose
C- Plug of the filler hose
D-Valve turner
E-Valve insert
F- Tire valveInserting sealant
1. Leave the object that caused the puncture in
the tire.
2. Remove sealant and the enclosed sticker from
the luggage compartment.
3. Adhere the sticker in the driver's field of vision.
4. Shake filler bottle A.5. Screw filler hose B onto the filler bottle.
The filler bottle is now open.
6. Unscrew valve cap from tire valve F.
7. Remove valve insert E from the tire valve with
valve turner D.
Keep the valve insert in a clean and dry place.
8. Remove plug C of the filler hose B.
9. Push filler hose onto the tire valve.
10.Hold filler bottle higher than the level of the tire
valve and press it together forcefully until the
bottle is completely emptied into the tire.
11.Pull filler hose off the tire valve.
12.Twist the valve insert firmly into the tire valve
using the valve turner.
13.Connect the compressor to the cigarette light-
er and inflate the tire to the prescribed tire
pressure.
Please observe the chapter “TIRE PRESSURES
FOR COLD TIRES” on Page 290.
14.Screw valve cap onto the tire valve.
15.Check the tire pressure after driving for around
10 minutes.
If the tire pressure is less than 22 psi (1.5 bar),
do not continue driving.
If a value of more than 22 psi (1.5 bar) is indi-
cated, correct the pressure to the prescribed
value.16.Please consult your authorized Porsche
dealer.
Care Instructions
After drying, any sealant that emerges can be
peeled off like a film.
Warning!
Risk of accident.
fHave the tire replaced by an authorized
Porsche dealer immediately.
fAvoid hard acceleration and high cornering
speeds.
fDo not exceed maximum speed of 50 mph
(80 km/h).
fPlease always observe the safety and oper-
ating instructions, which can be found in the
separate operating instructions for the sealant and on the compressor.

SpacersfUse the spacers only together with wheels and
fastening parts approved by Porsche.
Before having spacers fitted, find out about the
current approval status.911 Carrera 4, 911 Carrera 4S
Danger!
Risk of accident.
17 mm spacers must only be mounted on the
rear axle together with 11.5 J x 19 (67 mm
rim offset) wheels.
fAlways remove 17 mm spacers before
mounting other wheel sizes or an emergency
spare wheel because the wheel cannot be mounted correctly.

If 5 mm spacers are mounted, these must not be
removed to mount an emergency spare wheel.
Fitting snow chains
The use of snow chains is not permitted when
5 mm spacers are mounted.
Caution!
Risk of damage to the wheel housings if the
5 mm spacers are not removed before fitting
snow chains.
fTo permit the fitting of snow chains, have the 5 mm spacers removed on all 4 wheels.Note on operation
fTo fit/remove the spacers:
Please consult an authorized Porsche dealer.
fPlease observe the chapter “17 MM

Practical Tips, Emergency Service
Changing a wheel
Warning!
Risk of injury. The car may slip off the jack.
fMake sure that no one is in the vehicle when
jacking up and changing a wheel.
fAlways place the car on stable supports if work
has to be carried out under the car.
Risk of damage to the brake discs of the
Porsche Ceramic Composite Brake (PCCB).
fAlways screw in both assembly aids when changing a wheel.
Note
The tools required for changing a wheel (e.g. jack,
wheel bolt wrench, assembly aids) are not sup-
plied with the car.
Your authorized Porsche dealer will be pleased to
advise you.1. Fully apply the handbrake, engage 1st gear or
select position P and withdraw the ignition key.
2. Secure the car against rolling away, e.g. by
means of wedges under the wheels on the op-
posite side.
This is particularly important on slopes.
3. Slightly slacken the wheel bolts of the wheel to
be changed.
4. Raise the car until the wheel lifts off the
ground.
fPlease observe the chapter “LIFTING THE VE-
HICLE WITH A LIFTING PLATFORM OR GARAGE
LIFT” on Page 244.

and screw in the remaining wheel bolts. Initially
tighten bolts in diagonally opposite sequence
so that the wheel is centered.8. Lower the car completely.
9. Tighten wheel bolts in diagonally opposite
sequence.
Immediately after changing a wheel, use a
torque wrench to check the prescribed
tightening torque (130 Nm/96 ftlb.).
Checking tire pressure with a
pressure gauge1. Remove the valve stem cap from the tire.
2. Press the pressure gauge onto the valve stem.
Note on operation
fDo not press too hard or force the valve stem
sideways, or air will escape.
If the sound of air escaping from the tire is
heard, reposition the pressure gauge.
3. Read the tire pressure on the gauge stem and
compare it to the permissble tire pressure.
This information can be found on the tire pres-
sure plate or in the chapter Technical Data.
Please observe the chapter “TIRE PRESSURES
FOR COLD TIRES” on Page 290.
