Consumer Info rmation
today's a utomo biles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by veh icle owners.
Also , sa fet y and
en vironmental
concerns place very strict limits
on the nature of repairs and adjustmen ts to en­
g ine and transmission parts wh ich an owner can
perform .
Maintenance, adjustments and repairs usually re­
qu ire special tools, testing devices and other
equ ipment available to specially trained work ­
shop personnel in order to assure proper per­
forma nce, re liability and safety of the veh icle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliab ility of your
ve hicle and eve n void your vehicle warranty .
Therefo re, proof of se rvicing in a ccordance w ith
the m aintenance sched ule may be a condition for
up ho ld ing a possible wa rranty claim made within
the wa rranty pe riod.
Above all , ope rational safety can be adversely af­
fected, cre ating unne cessa ry risks fo r you and
your passengers.
I f in doubt about any servicing, have it done by
your author ized Audi dealer or any other properly
eq uipped and qualified workshop . We strongly
urge you to g ive your author ized Audi dealer the
opportunity to perform a ll scheduled mainte ­
nance and necessa ry repairs. Your dealer has the
facilities, origina l parts and tra ined specialists to
keep your veh icle runn ing prope rly.
Performing limited maintenance yourself
The fo llow ing pages describe a limited number of
procedures whic h can be performed on your vehi­
cle with ordinary tools, should the need arise and
tra ined personnel be unava ilable. Before per­
forming any of these procedures, always thor­
ough ly read all of the app licab le text and carefu l­
ly follow the instructions g iven . A lways rigorously
observe the
WARNINGS prov ided .
Befo re yo u check anything in the engine com ­
partment, always read and heed all WARNINGS
c::> & and c::> & in Working in the engine compart­
ment on page 323 .
