steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Als o, sa fe ty a nd en vir onm ent al con­
cerns place very strict limits on the nature of
repairs and adjustments to engine and trans­
miss ion parts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth­
er equipment available to specially trained
workshop personnel in order to assure proper pe rformance, reliab ility and safety of the vehi­
cle and its many systems.
Improper maintenance, adjustments and re­
pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­
ranty. Therefore, proof of servic ing in accord­
ance w ith the ma intenance schedule may be a
condition for upholding a poss ible warranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, c reating unnecessary risks for you
and your passengers.
If in doubt about any se rv icing, have it done
by your author ized Audi dealer or any other
p roperly equipped and qualified workshop.
We strong ly urge you to give yo ur autho rized
Audi dealer the opportunity to perfo rm all
schedu led maintenance and necessary repairs.
Your dea ler has the facilities, original parts
and trained specialists to keep your vehicle
running properly.
