Changing a wheel with removal of 17 mm
spacer
Danger!
Risk of accident if the spacers are not re-
moved before mounting 18 inch tires or col-
lapsible spare wheel.
f 17 mm spacers are always to be removed be-
fore mounting 18 inch tires or a collapsible
spare wheel, because the wheel cannot be fit-
ted correctly.
Caution!
Risk of damage to wheel housings if the
spacers on the rear axle are not removed be-
fore fitting the snow chains.
f 17 mm spacers must always be removed from
the rear axle when snow chains are to be fitted.
f Remove spacers if 18 inch tires, snow chains
or a collapsible spare wheel are mounted.
f It is not necessary to use a assembly aid for
mounting a wheel or spare wheel of the same
quality.
f For information on the spacers: Please
