close to one sidewall of the load
compartment.
2. Place the loop end of the strap
through the front lashing eye on
the appropriate side.

through the loop and pull it until
the strap is fastened securely to
the lashing eye.
4. Insert the strap through the
spokes of the wheel as shown in
the illustration.

using the buckle.
9 Danger
Always drive with folded up and
engaged rear seat backrests when
stowing a damaged full size wheel

Temporary spare wheel
Caution
The use of a spare wheel that is
smaller than the other wheels or in
combination with winter tyres
could affect driveability. Have the
defective tyre replaced as soon as
possible.
Only mount one temporary spare
wheel. Do not drive faster than
80 km/h. Take curves slowly. Do not
use for a long period of time.
If your vehicle gets a flat tyre on the
rear while towing another vehicle,
mount the temporary spare wheel in
the front and the full tyre in the rear.
