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” on Page 268.
The load capacity coefficient (e.g. “101”) 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 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, 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.

Practical Tips, Emergency Service
Flat Tire
Warning!
Failure to follow these instructions may result
in serious personal injuries to you or to by-
standers.
fIf you have a flat tire, move a safe distance off
the road. Turn the emergency flasher on and
use other warning devices to alert other
motorists. Set the parking brake.
fDo not park your vehicle where it may contact
dry grass, brush or other flammable materials.
The hot parts of the exhaust system could set
such materials on fire, thereby causing both
property damage and severe or fatal physical injury.
A tire sealant and compressor with pressure
tester are located in the toolbox in the luggage
compartment.
fPlease observe the safety and operating in-
structions on the special sealant bottle with a
special Porsche part number and on the com-
pressor – these are essential.Important note
Sealing the tire with the tire repair kit is only
an emergency repair. Even with the tire air-
tight, it may be used only for short trips in an
emergency.
The maximum permitted speed is 50 mph
(80 km/h).
fDo not use commercially available sealant or
tire inflating bottles.
Use only the tire sealant located in the tool box
in the luggage compartment.
Warning!
Risk of accident.
fHave tires replaced by a specialist workshop
as soon as possible.
fAvoid hard acceleration and high cornering speeds.

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 PRESSURE
FOR COLD TIRES” on Page 269.
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.

Wheel Bolts
Warning!
Risk of wheel bolt breakage and wheel sepa-
ration, resulting in severe personal injury or
death.
fFollow all instructions concerning wheel bolts. fAlways clean the wheel bolts before fitting.
fApply a thin coat of Optimoly TA (aluminum
paste) on the thread and between the bolt head
and movable spherical cap ring (arrows).
The bearing surface of the spherical cap
facing the wheel must not be greased.
fReplace damaged wheel bolts.
Only use the Original Porsche wheel bolts
specially designed for this vehicle type.
Tightening torque Tightening torque of wheel bolts:
130 Nm/96 ftlb. Wheel Securing Bolts The wrench socket for the wheel securing bolts is
in the tool box.
To loosen or tighten the wheel bolt with anti-theft
protection, a wrench socket with the appropriate
coding must be used between the wheel bolt and
the wheel-bolt spanner.
fWhen positioning the wrench socket, ensure
that it engages fully in the teeth of the wheel
bolt.
If the wheels have to be removed at the workshop,
please do not forget to hand over the wrench
socket for the wheel securing bolts along with the
car key.
Checking tire pressure with a
pressure gaugefPlease observe the chapter “TPC TIRE PRES-
SURE MONITORING” on Page 103.
1. 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 permissible tire pressure.
This information can be found on the tire pres-
sure plate or in the chapter Technical Data.
Please observe the chapter “TIRE PRESSURE
FOR COLD TIRES” on Page 269.
4. Remove the pressure gauge.

Please observe the chapter “TIRES/WHEELS” on Page 207.
Tire and rim sizes
Extensive tests are performed before specific tires and wheels are approved by Porsche. Your Porsche dealer has information
about approved tires and wheels and is happy to assist you. If aftermarket tires and/or wheels are installed which are not
approved by Porsche, the vehicle’s roadability and handling characteristics might be impaired. Since Porsche has no data on
such combinations, Porsche cannot stand behind the safety or durability of these aftermarket combinations.
* Snow chains Can be mounted only on the rear wheels; maximum speed 30 mph/50 km/h.
Use only Porsche authorized fine-link cross-type or edge chains.
Snow chain clearance can be guaranteed only with the tire + rim combination marked.
