Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specific
government test course. For example, a tire
graded 150 would wear one and a half (1-1/2)
times as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.
Traction AA, A, B, C
The traction grades, from highest to lowest, are
AA, A, B, and C and they represent the tire's ability
to stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Warning!
The traction grade assigned to this is based
on braking (straight-ahead) traction tests
and does not include cornering (turned)
traction, acceleration, hydroplaning or peak
traction characteristics. Temperature A, B, C
The temperature grades are A (the highest), B and
C, representing the tire's resistance to the
generation of heat and it
s ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperatures can cause the
material of the tire to de generate and reduce tire
life, and excessive temperature can lead to
sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109.
Grades B and A represent higher levels of
performance on the labora tory test wheel than the
minimum required by law.
Warning!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combin ation, can cause heat
buildup and possible tire failure, resulting
loss of control, leading to serious personal
injury or death.
Tire pressures
Danger!
Risk of accident.
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
pressure increases rate of wear of the
affected tires and cause damage.
f Always use an accurate tire pressure gage
when checking inflation pressures.
f Do not exceed the maximum tire pressure
listed on the tire sidewall. (Also refer to
”Technical data“).
f Please see the chapter “TIRE PRESSURE
PLATE” on page 283.
f Cold tire inflation pressure means: all tires
must be cold, ambient temperature maximum
68 °F (20 °C), when adjusting the inflation
pressure. Avoid sunlight striking the tires
before measuring cold pressures, since the
pressures would rise from temperature
influence.

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.

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.

Minor Repairs
305
Replacing the batteryThe service life of the battery is subject to normal
wear; it depends greatly on care, climatic
conditions, and driving conditions (distances,
loads).
f Only use an original Porsche battery, with the
correct part number, as a replacement. Only
this battery meets the spec ific requirements of
the vehicle.
f Please observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is connected or after a fully
discharged battery is charged, the PSM warning
light lights up on the instrument panel and
a message appears on the multi-function display
in the instrument panel to indicate a fault.
This fault can be corrected with a few
simple steps:
1. Start the engine. To do this, turn the igni tion key or the control
unit (on vehicles with Porsche Entry & Drive)
to ignition lock position 2, twice .
2. With the vehicle stationary, perform a few steering movements to the left and right and
then drive a short distance in a straight line
until the PSM warning light goes out and the
message is erased from the multi-function
display in the instrument panel.
3. If the warnings do not disappear, then:
Drive carefully to the nearest authorized
Porsche dealer to have the fault corrected.
4. After the warnings go out: Stop the vehicle in a suitable place.
5. Store the end position for the power windows. For information on storin
g the end positions for
the power windows:
f Please see the chapter “STORING END
POSITION OF THE DOOR WINDOWS AFTER
CONNECTING THE VEHICLE BATTERY” on
page 88.
6. Teach tires on vehicles with Tire Pressure Monitoring.
For information on teaching the Tire Pressure
Monitoring system:
f Please see the chapter “TIRE PRESSURE
MONITORING (TPM)” on page 127.
7. Store end position on vehicles with a slide/ tilt roof.
For information on storing the end position for the
slide/tilt roof:
f Please see the chapter “STORING END
POSITION OF THE SLIDE/TILT ROOF” on
page 90.
