Tightening wheel bolts
– Push the wheel wrench* fully onto the wheel bolt
– Grasp the end of the wrench* and turn the bolt to the right until it is tight.
WARNING
Slacken the wheel bolts only a little (about one turn) as long as the vehicle has
not yet been lifted with the lifting jack* - risk of accident!
Note
Apply pressure carefully with your foot to the end of the wrench* if it proves difficult
to slacken the bolts. Hold tight on the vehicle when doing this and ensure that you have
a steady position.
Raise vehicle
You have to raise the vehicle with the lifting jack* in order to be able to
take off the wheel.
Position the lifting jack* by selecting the jacking point which is closest to the wheel to

lower sill. The engraving is only visible after opening the door.
– Position the lifting jack* below the jacking point and move it up until its claw is
positioned directly below the vertical web of the lower sill.

– Turn the lifting jack* up further until the wheel is just clear of the ground.
Ground which is soft and slippery below the lifting jack* can cause the vehicle to slip
off the lifting jack*. It is therefore always necessary to place the lifting jack* on a solid
surface or use a wide and stable base. Use a non-slip base (e.g. a rubber foot mat) if
the surface is smooth, such as cobbled stones, a tiled floor, etc.
WARNING
Always raise the vehicle with the doors closed - risk of injury!
Take suitable measures to prevent the base of the lifting jack from slipping
off - risk of injury!
Not positioning the lifting jack* at the specified points can result in damage
to the vehicle. The jack can also slip off if it does not have sufficient grip - risk of
injury!
It is important to support the vehicle with suitable supporting blocks if you
wish to work under the lifted vehicle - risk of injury!
Securing wheels against being stolen*
You need a special adapter for slackening the safety wheel bolts.
– Pull off the full wheel trim/cap from the wheel hub or cap from the safety wheel
bolt.
