– The driver's skill level must be commensurate with the vehicle performance levels in the upper range limits, due to
increased safety risks in the upper range limits.

  • Sport tires are not suitable for use in cold, snowy, or icy conditions. At outside temperatures below 45 °F (7 °C) change to snow tires.
  • Notify anyone using your car of these characteristics and possible effects.

Loss of Road Surface Contact, Control over the Vehicle and Braking Ability

The reduced tire tread depth means that there is an increased risk of aquaplaning on wet roads.

  • When driving on wet or mud-covered roads reduce speed significantly.

Worn Tires

Sport tires have a smaller tread depth, and thus can reach their wear limit sooner.

It is important to check tire wear frequently to avoid risk of serious personal injury or death from worn tires.

  • Check tire wear frequently.

Driving on Race Circuit (e.g. Sports Driving Schools, Club Sport Events)
Brake fluid, brake pads and brake discs
Brake fluid absorbs moisture from the air over time. This accumulation of water lowers the boiling point and can impair braking action if the brakes are subjected to high temperatures, such as can occur on race circuits (sports driving school, Club Sport events).

The brake fluid should therefore not be more than 12 months old if the vehicle is driven on race circuits (sports driving school, Club Sport events).

  • For more information, see the " Maintenance" booklet.

Wear on the brake pads and brake disks depends to a great extent on the driving style and driving conditions. Wear on the brake components is increased as a result of high temperatures, such as can occur on race circuits (sports driving school, Club Sport events).

  • Before and after driving on race circuits (sports driving school, Club Sport events), it is important therefore to carry out a visual inspection of the brake pads and brake disks for wear.

Racing tires
The fitting of racing tires (e.g. slicks) for sporting events is not approved by Porsche.

Very high cornering speeds can be achieved with racing tires. The resulting transverse acceleration values would jeopardise the adequate supply of oil to the engine.

Porsche therefore refuses to accept any guarantee or liability for damage occurring as a result of non-compliance with this provision.

Setting and operating vehicle components when driving

Operating Components While Driving

Setting or operating the multi-function display, radio, navigation system, telephone or other equipment when driving could distract you from the traffic. You could lose control of the vehicle resulting in serious personal injury or death.

  • Operate the components while driving only if the traffic situation allows you to do so safely.
  • Carry out any complicated operating or setting procedures only with the vehicle stationary.
