Wheel bolts
The wheel bolts hold the wheel in place on the wheel hub.
Only use rims that have been tested and approved by Volvo and are included in Volvo's original product range.
Use a torque wrench to check that the wheel bolts are tightened correctly.
Do not grease the wheel bolt threads.
Wheel bolt lock kit*
To loosen or tighten the locking wheel bolt, turn the key in the locking bolt until it fully engages in the code grooves. When removing a wheel, always start with the locking wheel bolt. When installing a wheel, finish with the locking bolt.
When the wheel bolt key is not being used, stow it in its designated location in the foam block under the cargo compartment floor. This is important to remember so that the tool is available if the vehicle is taken to a workshop. If you lose the key, contact your Volvo retailer.
