Minor Repairs
Danger!
Driving on worn tires can result in loss of
control of the vehicle and could cause
serious personal injuries or death.
f Do not drive with worn tires or tires showing
cuts or bruises as they may lead to sudden
deflation and loss of control which could cause severe personal injury.
f If you notice that tires are wearing unevenly,
consult your authorized Porsche dealer.
Uneven wear may not alwa ys be due to improper
wheel alignment. It can be the result of individual
driving habits such as cornering at high speeds. If
the tire pressure is no t checked and adjusted
regularly, abnormal tire wear can also occur.
Tire caref Avoid damaging tires and wheel rims.
f I f y o u m u s t d r i v e o v e r a c u r b o r o t h e r o b s t a c l e ,
drive slowly and at an obtuse angle.
f Check tires for uneven wear and damage
before driving off.
f Remove imbedded material.
f Replace worn or damaged tires immediately.
f Keep oil, fuel, brake fluid, etc. away from tires.
f Replace missing valve stem caps.
f Keep tires inflated correctly.
f Wash tires when washing the vehicle. Also
clean inner side of wheels.
f Do not use abrasive cleaners when washing
the wheels.
f Check wheel rims for corrosion.
f Remove road salt, if driving in winter.
Tire damage, puncturefPlease see the chapter “HIGH-PRESSURE
CLEANING EQUIPMENT” on page 270.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected
tires.
f Check tires – including sidewalls – regularly for
foreign bodies, nicks, cuts, cracks and bulges.
f Cross curb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp curbs.
f In cases of doubt, have the wheel (particularly
the inner side) checked by an authorized Porsche dealer.

Minor Repairs
Snow chains
Warning!
Risk of damage to body, axle or brake
components.
f Use only the fine-link snow chains recom-
mended and authorized by Porsche so that
sufficient clearance between the wheel well
and the chain is assured.
f Please see the chapter “WHEELS, TIRES” on
page 325.
f Follow instructions issued by the supplier of the chains.
Fit snow chains only on the rear axle.
f Remove spacers if snow chains are mounted.
f Before fitting chains, remove accumulated ice
and snow from the wheel well.
f Vehicles with snow chains must not be driven
faster than 30 mph (50 km/h) .
Different states and countr ies have varying statu-
tory requirements regarding maximum speed.
f Check with local authorities for possible
restrictions.
f Remove chains as soon as the roads are free
of ice and snow.

Changing a wheel
Danger!
Failure to follow these instructions may result
in serious personal inju ry or death to you or
to bystanders.
Before changing the wheel
f If 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.
f Do not park your vehicl e 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.
f Passengers must not be in the vehicle when it
is jacked up.
f Before you change a wheel, be sure the ground
is level and firm. If necessary, use a board
under the jack to ensure that the jack does not
sink into the ground.
f Set the electric parking brake and block the
wheels opposite the flat tire on the other side
of the vehicle.
While operating the jack
f The jack is only to be used for changing a
wheel. Do not use it as a support to work under
the car. f
The car must be jacked up only at the
illustrated jacking points. Lifting at any other
place may damage the vehicle or may result in
personal injury. Never jack the car up by the
body or the bumpers.
f For safety reasons do not use tire inflating
bottles. Do not use co mmercially available
sealant bottles. Use only the tire inflating bottle
located in the luggage compartment.
Note
The tools required for changing a wheel (e.g. jack,
wheel bolt wrench, assembly aids) are not
supplied as standard with the vehicle. Your
authorized Porsche dealer will be pleased to
advise you.
Sequence of operation Warning!
The jack must be used on ly to raise the car
for wheel changing. The jack must never be
used as a support to work underneath the
vehicle. If the jack is accidentally dislodged,
you or bystanders could suffer severe
personal injury.
f Never jack up other ve hicles or other loads
with the jack.
f Always place the car on stable supports if you
have to work under it. When working under the
vehicle, always use safety stands specifically designed for this purpose. f
Please use a suitable knee rest to protect your
clothing against soiling.
1. Activate the electric parking brake and shift into 1st gear or move the PDK selector lever
to position P .
Remove the ignition key or control unit on
vehicles with Porsche Entry & Drive.
2. Switch on the emergency flasher if necessary.
3. Secure the vehicle against rolling away, e.g. by means of wedges at the wheels on the
opposite side.
This is particularly important on slopes.
4. Slightly loosen the wheel bolts on the wheel to be changed.
5. Lift the vehicle only at the specified jacking points.
6. Raise the vehicle until the wheel lifts off the ground.
f Please see the chapter “RAISING THE VEHICLE
WITH A LIFTING PLATFORM, TROLLEY JACK
OR STANDARD JACK” on page 290.
7. Remove 1 or 2 wheel bolts (see corresponding figure).

292
Minor Repairs
Screw in one assembly aid on vehicles without PCCB8. Screw in assembly aids instead of wheel bolts.
Caution!
Risk of damage to brake discs.
f Always screw in the assembly aids when changing a wheel.
Screw in two assembly aids on vehicles with PCCB9. Remove the remaining wheel bolts.
10.Take the wheel off and put a new wheel on.
fPlease see the chapter “WHEEL BOLTS” on
page 293.
11.Insert wheel bolts and tighten by hand.
12.Remove assembly aids and screw in remaining wheel bolts.
Initially tighten bolts only slightly in
diagonally opposite sequence so that
the wheel is centerd. 13.Inflate the tire if necessary.
f
Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/20 °C)” on page 326.
14.Lower the vehicle fully and remove the jack.
15.Tighten wheel bolts in diagonally opposite sequence.
Immediately after changing a wheel, use
a torque wrench to check the prescribed
tightening torque of the wheel bolts
(160 Nm/118 ftlb.).
Note on operation for vehicles with Tire
Pressure Monitoring
f On vehicles with Tire Pressure Monitoring, the
settings on the multi-function display must be
updated after the wheel change.
f Please see the chapter “TIRE PRESSURE
MONITORING (TPM)” on page 127.

Wheel Bolts fAlways clean the wheel bolts before fitting.
f Wheel bolts must not be greased.
f Replace damaged wheel bolts.
Only use genuine Porsche wheel bolts
assigned especially to this model or wheel
bolts of similar quality that have been
manufactured according to Porsche
specifications and production requirements.
Tightening torque
Tightening torque for wheel bolts: 160 Nm
(118 ftlb.) .
Security wheel boltsThe adapter (wrench socket) for the security
wheel bolts is stored in the tool tray under the
luggage compartment floor.
fIf the wheels have to be removed at the
workshop, do not forget to hand over the
socket for the security wheel bolts along
with the car key.
f To loosen or tighten the wheel bolt with anti-
theft protection, the adapter must be used
between the wheel bolt and the wheel
bolt wrench.
f When positioning the wrench socket, ensure
that it engages fully in the teeth of the
wheel bolt.
Flat Tire 1. Stop the vehicle as far away from the driving lane as possible.
The vehicle must be parked on a firm and flat
surface offering adequate grip.
2. Switch emergency flasher on.
3. Apply the parking brake.
4. Put the vehicle in 1st gear or move the PDK selector lever to position P.
5. Straighten the front wheels.
6. Remove the ignition key, or the control unit on vehicles with Porsche Entry & Drive, in order to
lock the steering and pr event the engine from
being started.
7. Get all passengers to leave the vehicle.
8. Set up the warning triangle at a suitable distance.Filling in tire sealantThe tire sealant and compressor with pressure
tester can be found in the tool tray under the
loadspace floor in the luggage compartment.
The tire sealant can be used to seal small cuts,
especially in the tire tread.
Sealing the tire with the tire sealant is only an
emergency solution so you can drive to the
nearest workshop. Even if the tire is air-tight,
