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.

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.

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,

Minor Repairs
Battery carefEnsure that battery is securely mounted.
f Keep terminals and connections clean and
properly tightened. Corrosion can be
prevented by coating the terminals and
connections with petroleum jelly or silicone
spray.
f Ensure that vent caps ar e securely tightened to
prevent spillage.
Checking the electrolyte fluid level
(only on low-maintenance batteries)
Generally, the electrolyte level must be checked
more often in summer than in the winter, and more
often when driving long distances.
f When adding water, use only clean containers.
In no case may alcohol (e.g. window cleaner
residues) be permitted to enter the battery.
f Unscrew and open the filler vent caps of each
cell.
With the car on a level surface, the fluid level
should meet the indicator mark in each cell.
f If necessary, top up with distilled water. Do not
use acid. Only fill up to the mark, otherwise the
electrolyte will overflow when the battery is
being charged and cause damage.
Winter operationDuring the winter months, battery capacity tends
to decrease as temperatures drop. Additionally,
more power is consumed while starting, and the
headlights, heater, rear window defogger, etc.,
are used more frequently.
f Let your Porsche dealer test the battery's
capacity before winter sets in.Vehicle storageIf the car stands for long periods in the garage or
workshop, the doors and lids should be closed.
f Remove the ignition key and, if necessary,
disconnect the battery.
Notes on operation
f When the battery is disconnected, the alarm
system ceases to function.
If the vehicle was locked before the battery
was disconnected, the alarm will be triggered
when the battery is reconnected.
To deactivate the alarm system:
f Lock the vehicle and unlock it again.
Alarm system, central locking
f The status of the central locking and alarm
system is not changed by disconnecting the
battery. Maintenance notes
Even if you put your vehicle out of operation, the
battery still discharges.
The battery will discharge more quickly if your
vehicle is not driven on a daily basis over a
distance of several miles. The more often you
drive your vehicle, and
the longer the distance
driven on each trip, the more opportunity the
vehicle‘s charging system w ill have to recharge the
batteries.
f To preserve its efficiency, charge the battery
about every 6 weeks.
f Check the battery acid level and top off with
distilled water if necessary.
f Store a battery that has been removed in a
dark, cool place, but not subject to freezing.
