Installing Wheel
- Risk of squashing or crushing
→ Secure components to prevent them from falling down.
NOTIFICATION
Removing/fitting wheels
- Risk of damage to (ceramic) brake discs
→ Use two assembly pins when removing and fitting the wheel.
→ Carefully guide the wheel towards the wheel hub, thereby preventing any heavy impact on the (ceramic) brake disc.
Information
For vehicles with Tyre Pressure Monitoring (TPM):
- Every new set of wheels or wheel change must be communicated to the control unit. Even if the new wheels have the same specifications as the old ones.
- To do this, select TPM, Settings, Tyre type and Tyre size in the main menu on the instrument cluster and confirm your selection. The control unit stores these values while the vehicle is driving (at more than 25 km/h (16 mph)). The current tyre pressure is not available during this time.
- For information on teaching the TPM system, see
> 4X00IN - GENERAL INFORMATION ON THE TYRE PRESSURE MONITORING SYSTEM (TPM)
Information
The use of power tools (impact bolter) for loosening and securing the wheel bolts is not permitted.
