The engine oil used in your Audi needs the right kind of
oil.
The engine in your Audi is a sophisticated powerplant that was built
to exacting specifications . This engine needs the right kind of
engine oil that meets specifications regarding quality and viscosity
so that it can run smoothly and re liably . Choosing the right oil and
changing oil within the time and mileage intervals printed in your
vehicle's Maintenance
& Warranty booklet matters a lot more today
than it did years ago. Audi has developed a special quality standard
f or engine oil that wil l help assure that your vehicle's engine wi ll get
the lubrication it needs for proper operation .
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine
lubrication that can outlast traditional petroleum-based oils,
making them a smart choice for use throughout the life of your Audi .
Whether you use synthetic or petroleum -based engine oil, the oil
that you use must conform to Audi's oi l quality standard VW 502 00
to help keep your vehicle 's engine running smoothly and help

M aintaini ng proper t ire pressure is one of the most im po rta nt
thi ngs you ca n do t o help avo id sud den t ire fa ilu re. Underi nflated
tires are a major cause of sudden tire failure. Keeping tires at the
ri ght pressure is also importa nt for safe and r espo nsive ve hicle
handling, traction, braking and load carrying.
Tire pressures are
particularly important when the vehicle is being driven at higher
speed s, and then especially when heavily loaded even within the
•
T ire pressure generally refe rs to the amou nt of air in a t ire that it
needs it to do its job and safely carry the combined load of the entire
veh ic le and i ts c ontents. Tire p ressu re is measu red in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSI) . Tir e p res su re is based in part on th e vehic le's design and
load lim it - the greatest amount of weight that the veh ic le can carry
safely and the tire size . The proper tire pressure is frequently
re ferred to as the "recommended cold t ire infla tion pressure." A ir in
the tires expands when the tire heats up because of internal friction
when it fl exe s i n us e. The tir e press ure is high er w he n th e t ire has
warmed up than when it is "cold." It is the inflation pressure in a "c old" tire that c ounts. Theref ore , yo u sho uld never le t air ou t of a

the e nv ironment. •
Important considerations for you and your
vehicle
T he increasing use of elec tronics, sophisticated fue l injection and
emission con trol systems, and t he gene rally increasing tec hn ical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repai rs which can be carried ou t by vehic le
owners.
Also , safety and environmental concerns p lace very strict
limits on the nature of repairs and adjustments to engine and trans ­
m iss ion parts whic h an owne r can perform.
Maintenance , adjustments and repairs usua lly require special tools ,
t es ting dev ices a nd othe r eq uipment availab le to s pec ial ly t rai ned
workshop personne l in order to assure proper performance , reli ­
abil ity and safe ty of the vehicle and its many sy stems .
Im proper maintena nce, adjustments and repairs can impa ir the
operation and reliability of your vehicle and even void your vehicle
wa rranty. T here fore, proof o f servic ing in acc orda nce with the main­
tenance schedule may be a condition for upholding a possib le
warranty cla im made with in t he war ran ty per iod .
Above all, operationa l safety can be adversely affected, creating
unnecessary risks for you and your passengers.
I f in doubt about any servicing, have it do ne by your auth orized Audi
