Notes on wheel change
Pl ease rea d the information ¢ page 191, New
tires and replacing tires and wheels,

going to use a spare t ire which is different
from the tires on your ve hicle.
Afte r you change a tire:
- Check the tire pressure on the spare imme ­
diately after mounting .
- Have the wheel bolt tightening torque
che cked with a torque wrench as soon as
possible by your authorized Audi dealer or
a qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lb (120 Nm) .
- If you notice while changing a tire that the
wheel bolt s are co rroded and diffi cult to
turn , then they should be replaced before
you check the t ightening torque.
What do I do now? 211
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as

steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also , sa fe ty a nd en vir onm ent al con­
cerns place very strict limits on the nature of
repairs and adjustments to engine and trans­
miss ion parts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth­
er equipment available to specially trained
workshop personnel in order to assure proper pe rformance, reliab ility and safety of the vehi­
cle and its many systems.
Improper maintenance, adjustments and re­
pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­
ranty. Therefore, proof of servic ing in accord­
ance w ith the ma intenance schedule may be a
condition for upholding a poss ible warranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, c reating unnecessary risks for you
and your passengers.
If in doubt about any se rv icing, have it done
by your author ized Audi dealer or any other
p roperly equipped and qualified workshop.
We strong ly urge you to give yo ur autho rized
Audi dealer the opportunity to perfo rm all
schedu led maintenance and necessary repairs.
Your dea ler has the facilities, original parts
and trained specialists to keep your vehicle
running properly.
Performing limit ed m aint enance yours elf
The following pages describe a limited num­

need arise and trained personnel be unavaila­
ble. Before performing any of these proce­
dures, always thoroughly read all of the app li­
cable text and carefully follow the instruc­
tions given . Always rigorously observe the

_& WARNING
- Serious personal injury may occur as a re­
sult of improperly performed mainte­
nance, adjustments or repa irs.
- Always be extremely careful when work­
ing on the vehicle. Always follow com­
monly accepted safety pract ices and gen­
eral common sense. Never r is k personal
inju ry.
- Do not attempt any of the maintenance,
checks or repairs descr ibed on the fol­
lowing pages if you are not fu lly fam iliar
with these or other procedures with re ­
spect to the vehicle, or are uncertain how
to proceed .
- Do not do any work without the proper
too ls and equipment. Have the necessa ry
work done by your authorized A udi deal­
er or another proper ly equipped and
qualified workshop.
- The engine compartment of any motor
veh icle is a potentially hazardous area.
Never reach into the area around or
touch the radiator fan. It is temperature controlled and can sw itch on suddenly -
even when the engine is off and the igni­
tion key has been removed. The rad iator
fan switches on automa tical ly when the
coo lant reaches a certain temperature
and will continue to run until the coo lant
temperature drops .
- Always remove the ign ition key before
anyone gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work under­
neath the vehicle. The jack supplied with
the vehicle is not adequate for this pur­
pose and cou ld collapse causing serious
personal injury.
- If you must work underneath the vehicle
with the wheels on the ground, always
make sure the vehicle is on leve l ground,
that the wheels a re a lways secure ly
b locked and that the engine cannot be
started.
