Failure to Secure Vehicle

An unsecured or incorrectly secured vehicle can move unintentionally or fall down off the lifting equipment, e.g. jack or lifting platform, during repairs.

  • If you have to work on the engine while it is running, always put the parking brake on and put the gearshift lever in neutral or the PDK selector lever in position P.
  • Always place the vehicle on stable supports if work has to be carried out under the vehicle.
    The car jack is not suitable for this.
  • Lift the vehicle only at the specified jacking points on the vehicle underbody.
  • Never start the engine while the vehicle is raised. Engine vibrations can cause the vehicle to fall down.
  • When working under the car without safety stands but with the wheels on the ground, make sure the car is on level ground, the wheels are blocked, and that the engine cannot be started.
    Remove the ignition key.

Information

  • Incomplete or improper servicing may cause problems in the operation of the car. If in doubt about any servicing, have it done by your authorized Porsche dealer.
    Improper maintenance during the warranty period may affect your Porsche warranty coverage.
  • Some countries require additional tools and special spare parts to be carried in your vehicle. Please make enquiries before driving abroad.


Tires/Wheels
The original equipment tires and wheel rims on your Porsche comply with all applicable Federal Motor Vehicle Safety Standards.

For your safety remember the following:
–Wheel rims and wheel bolts are matched to fit your Porsche.
– If you intend to use other than original equipment wheels, be sure that they conform to Porsche specifications for your model.
Only tires with the same make and with the same specification code (e.g. "N0", "N1"...) can be mounted.
– The use of wheel rims and wheel bolts that do not meet specifications of the original factory installed equipment will affect the
safe operation of your vehicle.
– Before you plan on exchanging wheels, or snow tires already mounted on the wheel rims, consult your authorized
Porsche dealer. Your dealer has the technical information necessary to advise you which wheel rims and wheel
bolts are compatible with the original factory installations.
