environmental
concerns place very strict limits

Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and o ther
equipment available to specially trained work ­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and
its many systems.
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for upholding a possible warranty claim made within
the warranty period.
Above all , operational safety can be adversely af­
fected, creating 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. We strongly urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­ nanc e and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly .
