264 Vehicle care
To remove:
1. Open the floor cover.
2. The spare wheel is secured with a
wing nut. Turn wing nut
anticlockwise and remove the
spare wheel.
Under the spare wheel there is the
box with vehicle tools.
3. When, after a wheel change, no
wheel is placed in the spare wheel
well, secure the tool box by
turning right back the wing nut and
close the floor cover.
Stowing the replaced full size
wheel in the spare wheel well
The spare wheel well is not designed
for all permitted tyre sizes. If a wheel
wider than the spare must be stowed
in the spare wheel well, the thread
bolt for mounting the wheel must be
replaced by an extension bolt, located
in the tool box 3 252. To replace the
bolt:
● Remove tool box from the spare
wheel well.
● Install the hexagon key of the
wheel wrench ensuring that it
locates securely on the bolt.
● Turn the wheel wrench
anticlockwise to loosen the bolt.
Remove the bolt.
● Take the extension bolt from the
tool box 3 252 and screw it in
hand-tight using the hexagon key
of the wheel wrench.
● Store the tool box and the
damaged wheel outside up in the
spare wheel well and secure it by
turning the wing nut clockwise on
the bolt.
The floor cover can be placed on the
projecting wheel.
To fit the spare wheel in the well after
renewing the defective wheel use the
short thread bolt again. Exchange the
bolt in the same way.
