2009 PORSCHE PANAMERA warning

Minor Repairs
285
In case of tire damage, where it is uncertain
whether there is a break in the ply with all its
consequences or tire damage caused by thermal
or mechanical overloading due to loss of pressure
or any other prior damage, we recommend that
the tire be replaced for safety reasons.
If one faulty tire is replac ed it should be noted that
the difference in tread depth on one axle must not
exceed 30%. Handling inconsistencies may result.
f Perform a visual inspection if necessary.Tire replacementsfUse only tire makes and types tested by
Porsche.
If you do not use a Porsche recommended
replacement tire, make sure that you
purchase your new tires from a reputable tire
dealer and that the dealer complies with all
manufacturers warnings for those tires.
Only tires with the same manufacturer and
with the same specific ation code (e.g. “N0”,
“N1”…) should be mounted on the vehicle.
Before mounting new tires, check with your
Porsche dealer about the current release
status.
Tires should be replaced no less than on one axle
at the time. Only tires of the same make and type
must be used. Mixed tire s are not permissible and
will affect vehicle performance, safety, and can
affect vehicle warranty. Porsche dealers can recommend the most current
replacement tire options for your vehicle.
Initially, new tires do not have their full traction.
You should therefore drive at moderate speeds
during the first 60 - 120 miles (100 - 200 km).
Tires must always remain
on the same side of
the vehicle.
When wheels are removed, the direction of
rotation and position of each wheel should be
marked.
If new tires are installed only on one axle, a
noticeable change in hand ling occurs due to the
different tread depth of the other tires. This
happens especially if only rear tires are replaced.
However, this condition disappears as the new
tires are broken in.
f Please adjust your driving style accordingly.
Installation of new tires should only be done by a
qualified tire technician.
Valves
f Use only plastic valve caps.
f The rubber valves must be replaced whenever
the tires are changed.
f The fitting and replacement specifications
must be observed for metal valves.
f Only use Original Porsche metal valves.
f Protect the valve inserts against soiling with
valve caps. Soiled valve inserts can cause a
gradual loss of air.
Parking at the curb
Danger!
Hard impacts against curbs (or traffic
islands) are dangerous and may cause
hidden tire damage which is not noticeable
until later. Such damage can result in
accidents at high speeds causing serious
personal injury or death. Depending on the
force of impact, the edge of the rim can also
be damaged.
f After such an impact, have the wheel checked
by an expert.
f If you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle. Exercise care when parking along curbs.
Maintenance note
Tire repairs are not permissible under any
circumstances.
Wheel alignment, wheel balancingAs a precaution, have wheels with summer tires
balanced in the spring, and those with mud and
snow tires before winter. Unbalanced wheels may
affect car handling and tire life.
Only the specified weights may be used for wheel
balancing.

288
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.
