Also , s afety a nd
en viro nm enta l
concerns place very strict limits
on the nature of repairs and adjustments to en­

qu ire spec ial tools, testing devices and other
equ ipment available to specially trained work­
shop perso nnel in order to assure proper per­
formance, reliab ility and safety of the vehicle and
its many systems.
Improper ma intenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of se rv icing in accordance with
the m aintenance schedule may be a condi tion for
upho ld ing a possib le warranty cla im made w ith in
the warranty period .
Above all, operational safety can be adversely af­
fected, creating unnecessary r isks fo r you and
your passengers.

your author ized Audi dealer or any prope rly
equ ipped and qua lified workshop. We st rongly
urge you to give your authorized Audi dealer the
opport unity to perform all sched uled mainte­
nance and necessary repairs. Your dealer has the
