complexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, s afe ty and en vironm ental con­
cerns p lace very strict limits on the nature of
repairs and adjustments to engine and trans ­
miss io n pa rts which an owner can perform .
Maintenance, adjustments and repairs usua lly
require special tools, testing devices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliability
of your vehicle and even vo id your vehicle war­
ranty. The refo re, p roof of servic ing in accord­
ance w ith the ma intenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period .
Above all, operational safety can be adversely
affected, c rea ting unnecessary risks for you
and your passengers.
I f in doubt about any servicing, have it done
by your authori zed Audi dealer or any othe r
p roperly equipped and q ualified workshop .
We strong ly urge you to give your aut horized
Audi dealer the opportunity to perfo rm all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, or iginal parts
and trained spec ialists to keep your vehicle
running properly .
