Practical Tips, Emergency Service

A - Socket for the central nut under the front lid

Wheel change

f Have the wheel changed at an authorized 

Porsche dealer. 

f Do not attempt to loosen central nut with 

conventional tools.

Because of the large breakaway torque as well as 

the high tightening torque of the special central 

nut, workshop equipment is necessary to change 

a wheel. 

(E.g. a torque wrench with 1 inch square, and at 

least 550 Nm (407 ftlb.)).

Porsche Ceramic Composite Brake (PCCB).
f When changing a wheel, make sure that the 

brake discs are not damaged.

Socket

A suitable socket A for loosening or tightening the 

central nut can be found in the compartment for 

the roof panels under the front lid. 

The socket is not suitable for impact or impulse 

screwdrivers.

The tools required for changing a wheel (e.g. jack, 

torque wrench) are not supplied with the car.
The socket is adjusted for the special teeth of the 

central nut. To avoid damage, only this socket 

may be used to loosen or tighten the central nut.
f When positioning the socket, ensure that it 

engages fully in the teeth of the central nut.

f Always leave the socket in the compartment 

for the roof panels so that it is always available 

in the event of a flat tire.
