comp lexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, safet y and environm ent al
con-
cerns place very strict limits on t he nat ure of
repairs and adjustments to engine and trans -
mission parts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth-
er equipment availab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi-

Improper ma intenance, adjustments and re-
pairs can impair the operation and reliability
of your vehicle and even void your vehicle war-
ranty. Therefo re, proof of servicing in accord-
ance with the maintenance sched ule may be a
condition for upholding a poss ible warranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, creat ing unnecessary risks for you
and your passengers.
If in doubt about any servicing, have it done
by your authorized Audi dealer or any other
properly equipped and qualified workshop .

Audi dealer the opportunity to perform all
schedu led maintenance and necessary repairs .

and trained spec ialists to keep your vehicle
