Checking Condition

WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

Tyres are a safety element that fulfil the demands placed on them only if they have the correct air pressure and a sufficient tread depth.

WARNING: Risk of accidents if the air pressure in the tyres falls below the minimum, if the tread depth is insufficient or if there are foreign bodies, pricks, cracks and bulges in the sidewall (ply breakage).

Modified handling behaviour can cause accidents and major material damage.

→ The air pressure must never fall below the values specified (these are minimum pressures).

→ The tread depth must never fall below the minimum value.

→ A visual inspection of the tyres (for cracks, pricks, bulges in the sidewall and/or foreign bodies) must be carried out.

Information

The tyre pressure was changed in model year 2006 . → Information
For vehicles with Tire Pressure Monitoring, which can be identified by aluminium valves, the tyre pressure should be adjusted according to the filling information in the multi-function display. To do this, select >> Main menu >> Tyre pressure >> -Settings- << and adjust the deviation values so that they range from 0.0 bar to +0.1 bar. Fill the tyres according to the display using the tyre-inflating device. Example: If the tyre-pressure display shows >> Settings << = -0.2 bar, 0.2 bar must be added.

Due to the pressure and temperature relationship (0.1 bar/10° C), the actual pressures displayed in the -Basic tyre pressure screen- in the multi-function display, or on the pressure gauge of the tyre-inflating device, can deviate from the required pressure specification on the tyre pressure plate, which is defined at 20° C. This is particularly the case if the tyre air temperature is significantly above (higher values) or significantly below (lower values) 20° C. Changes in the tyre pressure are displayed up to a max. of 1 minute later in the >> Settings <<.

For vehicles with Tire Pressure Monitoring, always use plastic valve caps. Valve caps protect against dust, dirt and humidity, and therefore against damage (corrosion).

Check condition and tyre pressure.
Valve caps protect the valve from dust and dirt and therefore from damage.
Always screw on valve caps tightly and replace missing valve caps.
