5.The polygon tool contains an auxiliary tool. Remove this from the square and replace it afterwards.Use the auxiliary tool to carefully lever the wheel-hub cap out of its seating. For this purpose, insert the metal tongue of the auxiliary tool deep into the opening groove A on the central bolt and then swivel the handle back.
6. Position the polygon tool and insert it until it engages . This opens the safety lock on the central bolt.
Information
A very high torque is required to loosen the central bolt, especially if it has not been opened in a long time.
fTurn in the correct direction.fMake sure there is sufficient clearance so that neither people nor vehicle parts will be harmed if the lever breaks away.fThe wheel should be prevented from turning by getting a second person to brake firmly using the brake pedal.fHold the steering wheel securely when loosening the front wheels.
Risk of damage to the central bolt lock.fWhen loosening the central bolt, make sure that the tool remains pushed on fully and does not slide out of position.
7. Unscrew the central bolt and set it down in such a way that no dirt can enter the cone area or the thread.

There is a risk of damage to brake disks on vehicles with Porsche Ceramic Composite Brake (PCCB).fDo not tilt the wheel when removing it.
8. Remove wheel carefully. 9. Check that the toothed locking bolt C moves smoothly.When you press the bolt into its element, it must return firmly to its original position without catching.The toothing on the locking bolt C must not be damaged.The cone ring A must turn easily in the central bolt.10. There must be a generous coating of grease on the thread of the central bolt and wheel hub. Whenever wheels are changed, apply some aluminium paste to the trapezoidal thread on the wheel hub.
Always grease the conical area A (45° area) of the central bolt and the cylindrical part B of the wheel hub with a light coating of aluminum paste before fitting the central bolt. Make sure that no dirt sticks to the components.All other parts must be free of grease.
Deferring inspection, maintenance and replacement measures can result in accidents.
Carry out a visual inspection of all parts before fitting the wheel.
The central bolt and central bolt lock are safety- related components. Always check them for signs of wear and damage.fThe affected parts must be replaced by your authorized Porsche dealer if they are damaged or if you suspect that they are not in perfect working order.fThere must be no scratches or cracks on the cone area, thread or inner teeth of the bolt.fThe cone ring must turn easily in the central bolt.fThere must be a generous coating of grease on the thread of the central bolt and wheel hub.fOnly brake disks that were approved for the central lock may be fitted.fAll contact surfaces on the wheel, wheel hub and brake disk as well as the thread in the wheel hub must be free of abrasion, sand, dust or shavings.
fThe central bolt lock C prevents the central bolt from being lost and must not therefore be removed from the wheel hub.
There is a risk of damage to brake disks on vehicles with Porsche Ceramic Composite Brake (PCCB).fDo not tilt the wheel or place it against the brake disk when mounting it.
11. Fit the wheel carefully.

Information
The vehicle must not be standing on the wheel to be secured during fitting.
12. Insert the central bolt into the polygon tool (until it engages), fit the central bolt at right angles to the wheel hub and screw it on without tilting.13.Tighten the central bolt to 443 ftlb. (600 Nm) using a suitable torque wrench. Prevent the resultant turning of the wheel by getting a second person to firmly press the brake pedal. Hold the steering wheel securely when tightening the front wheels.
14. Loosen the central bolt again by 1/4 turn. 15. Tighten the central bolt again to 443 ftlb. (600 Nm) .
Information
If you do not have a suitable torque wrench in a breakdown situation, the emergency procedure for fastening the central bolt must be performed.fPlease see the chapter “CENTRAL BOLT EMERGENCY FASTENING” on page 263.
16. Remove the polygon tool and check whether the locking pin C has already automatically engaged in the central bolt. The locking pin then completely covers the inner teeth of the central bolt. The locking pin is usually still in the rear position and must be turned to the left and right slightly using the auxiliary tool until it engages with spring force in the central bolt.

17. Position the wheel-hub cap in the central bolt so that the positioning tab is facing the screw groove . Then press the cap into position.Do not drive without the wheel-hub cap in place. Otherwise water and dirt can get into the central bolt and impair the function of the central bolt lock.A little grease on the rubber ring makes fitting and subsequent removal easier.18.The vehicle can now be lowered.
Rim Cleaner
Using rim cleaners: Rim cleaners can bleach the anodized surface of the central bolt.fOnly use rim cleaners approved by Porsche and use these sparingly and in accordance with instructions for use.
Central Bolt Emergency Fastening
If there is no suitable torque wrench available for tightening the central bolt to the high tightening torque of 443 ftlb. (600 Nm) in an emergency situation, the emergency fastening procedure must be used.fThe central bolt must always be fitted using the original tool (stored in the luggage compartment, see point 4).fThe vehicle must not be standing on the wheel to be secured during fitting.1. Tighten the central bolt with great force using a long lever (3/4-inch adapter required) and loosen again by 1/4 turn.2. Tighten the central bolt using a commercially available torque wrench (3/4-inch adapter required) to exactly 74 ftlb. (100 Nm).

Filling in tire sealant
The tire sealant can be found in the right-hand box in the luggage compartment. The compressor is located under the cover in the luggage compartment.
The tire sealant can be used to seal small cuts, especially in the tire tread.
Sealing the tire with the tire sealant is only an emergency solution so you can drive to the nearest workshop. Even if the tire is air-tight, it may only be used for short journeys in an emergency.
The tire sealant set comprises: – a filler bottle– a filler hose– a valve turner– a spare valve insert– a sticker with the maximum permitted speed– a compressor– operating instructions
Always observe the following points:fUse the tire sealant only in the case of cuts or punctures no larger than 0.15 in. (4 mm).fNever use the tire sealant if the rim is damaged.
The sealant is highly flammable and harmful to health.fFire, naked flame and smoking are prohibited when handling tire sealant.fAvoid contact with skin, eyes or clothing due to caustic chemical properties of the tire sealant.fKeep tire sealant away from children.fDo not inhale vapors, due to the consequent harm to personal health resulting in serious personal injury or death.
In the event of contact with sealant:
fIf sealant gets on your skin or into your eyes, thoroughly rinse the affected part of your body immediately with plenty of water.fChange soiled clothing immediately.fSee a doctor immediately in the event of an allergic reaction.fIf sealant is swallowed, thoroughly rinse out the mouth without delay and drink plenty of water. Do not induce vomiting.See a doctor immediately.
