Some of the more challenging repairs covered in this manual
cal¡ for the use of BMW special tools. This, however, does not
automatically mean that the job is too complicated or out of
reach of the novice .
Many of the BMW special tools mentioned in this manual are
simply the best thingto useto do the jobcorrectly. In these cas-
es, the tool is identified with a BMW part number . See your au-
thorized BMW dealer parts department for information on how
to order special tools.
There are some jobs for which expensive special tools are
essential, and not a cost-effective purchase for one-time repair
by the do-it-yourself owner. This manual includes such repairs
for the benefit of these with the necessary experience and ac-
cess to tools. Forthe do-it-yourselfer, the need for special tools
is noted in the text, and whether or not BMW dealer service is
recommended.

ruin a tire or rim than to risk being hit.

mat. Remove the spare tire from the tire storage tray.
