A WARNING ~
-You or your passengers could be injured
while changing a wheel if you do not fo l­
low these safety preca utio ns:
- Position the vehicle jack on ly at the
designated lifting points and align the
jack. Otherwise, the vehicle jack could slip and cause an injury if it does not
have sufficient hold on the vehicle.
- A soft or unstable surface under the
jack may cause the vehicle to slip off
the jack . Always provide a firm base for
the jack on the ground. If necessa ry,
use a stu rdy board under the jack.
- On hard, s lippery surface (such as t iles)
use a rubber mat or simi lar to prevent
the jack from slipping.
- To help prevent injury to yourself and
your passe ngers:
- Do not raise the vehicle until you are
sure the jack is securely engaged.
- Passengers must not remain in the ve­
hicle when it is jacked up.
- Make sure that passengers wait in a
safe place away from the vehicle and
well away from the road and traffic .
- Make sure jack pos ition is correct, ad ­
just as necessary and then continue to raise the jack.
- Changes in temperature or load can af­
fect the height of the vehicle.

264 What do I do now?
and the hub. Remove all dirt from these
surfaces before remo unting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in
the right direction.
Using a spare tire with a tread pattern
intende d fo r use in a specific direction
When using a spare tire with a tread pattern
intended for use in a specific direction, p lease
note the fo llowing:
- T he direction o f rotation is marked by an a r­
row on the side of the tire.
- If the spare t ire has to be installed in the in ­
correct di rection, use the spare tire only
temporarily since the tire will not be able to achieve its optimum performance character­
ist ics with regard to aquaplaning, noise and
wear.
- We recommend that you pay particular at­
tent ion to this fact during wet weather and
that you adjust your speed to matc h road
condit ions .
- Replace the flat tire w ith a new one and
have it installed o n your ve hicle as soon as
poss ible to restore the handling advantages
of a un id irect iona l tire .
Notes on wheel changing
Please read the information i:> page 246, New
t ires and repla cing tires and wheels
if you are
going to use a spare tire which is differen t
from the tires on your ve hicle.
Afte r you cha nge a tire :
-Check the t ire pressure on the spare imme ­
diately after installation .
- Have the wheel bolt tightening torque
checked with a torqu e wrench as soon as
possib le by your authorized Audi dealer or
a qualified servi ce station .
- With st eel and alloy wheel rims , the wheel
bolts are correctly tightened at a torque of
90 ft lb (120 Nm) . -
If you notice that the wheel bolts are cor­
roded and difficult to turn while chang ing
a tire , they should be repl aced before you
check the t ightening torque.
- Repl ace the flat ti re w ith a new one and
have it installed on your vehicle as soon a s
possible. Remount the wheel cover .
Until then , dri ve with extra care and at re­
duced speeds.
A WARNING
- I f you are going to equip your vehicle
with tires or rims which differ from those
which were factory installed, then be
sure to read the information
i:> page 246,
New tires and replacing tires and
wheels.

even a flat tire and the jack and tool ki t
are properly secu red in the luggage co m­
p ar tment and are no t loo se in the pas­
senger compartment .
- I n an accident or sudde n maneuver they

complexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, safe ty and e nvir onm en tal con­
cerns p lace very strict limits on the na ture of
repairs and adjustments to engine and trans ­
miss io n pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing dev ices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliability
of your vehicle and even void your vehicle war­ ranty. The refo re, p roof of servici ng in accord­
ance w ith the maintenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, crea ting 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 q ualified workshop .
We strong ly urge you to give you r a uthorized
Audi dealer the opportunity to perform all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, or iginal parts
and trained spec ialists to keep your vehicle
running properly .
Performing limit ed m aintenance you rself
The fo llowing pages describe a limited num­
ber of procedures which can be performed on
your vehicle with ordinary too ls, should the
need arise and trained personnel be unavaila­
b le. 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 obse rve the
WARNINGS provided .
Before you check anything in th e engine
compartment, a lway s re ad and heed all
Con sumer In formation 28 1
WARNINGS ¢ & and¢ & in Working in the
engine comportment on page 219 .
A WARNING
-Ser ious 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
mon ly accepted safety pract ices and gen­
eral common sense . Never r isk personal
lnJU ry .
- Do not attempt any of the ma intenance ,
checks or repairs descr ibed on the fol­
lowing pages if you are not fully fam iliar
wit h these or othe r pro cedures with re­
spect to t he veh icle, or are uncerta in how
to p roceed .
- Do not do any work without the proper
too ls and equipment. Have the necessary
work done by your authorized A udi deal ­
er or another proper ly equipped and
qualified workshop .
- The engine compartment o f any motor
veh icle is a potentially hazardous area.
Never reach into the area around or
touch the rad iator fan. It is temperature
contro lled and can switch on suddenly -
even when the engine is
off . The radiator
fan switches on automat ically when the
coo lant reaches a certai n temperature
and will cont inue to run until the coo lan t
temper ature drops.
- Always sw itch
off the ignition before any­
one gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work under­
neath the vehicle . The j ack s upplied with
the vehicle is not adequate for this pur­
pose and cou ld collapse causing serio us
personal i njury .
- I f you must work unde rneath the vehicle
with the wheels on the ground, a lways
make sure the vehicle is on leve l ground,
that the wheels are a lways securely
blocked and that the engine cannot be
