• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of
coo lant additive to 60% .
• When adding coolant additive to your cooling system, remember:
-We recommend using only coolant additive G12++ (check the
label) for your vehicle. This coolant additive is available at autho­
r iz ed Audi dealers. Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle 's
eng ine coolant. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty. •
Checking the engine coo lant level
The engine coolant level can be checked with a quick
glance.

compartment: Coolant
expansion tank
Vehicle OP-eration
Before you check anything in the engine compartment,
always read and heed all WARNINGS=> & in "Working in
the engine compartment" on
page 289.
- Turn off the ignition.
- Read the engine coolant level from the coolant expansion
tank=> fig. 247 . With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
"max'' marking .
The locat ion of the coolant expans ion tank can be seen in the engine
compartment illustration=>
page 290.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped with an electric coolant level sensor .
When the coolant level is too low, the warn ing light in the Auto-Check
System =>
page 29 will blink until you add coolant and the level has
been restored to normal. Even though there is an electric coolant
level sensor, we still recommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event of
coolant loss, the cooling system should be inspected immediately by
your authorized Audi dealer .
It is not enough merely to add coolant.
In a
sealed system, losses can occur only if the boiling point of the
coo lant is exceeded as a result of overheating.
& WARNING
The cooling system is under pressure and can get very hot. Redu ce
the risk of scalding from hot coolant
by following these steps.
• Turn off the engine and allow it to cool down.

Tires
General notes
Tires may be the least appreciated and most abused
parts of a motor vehicle.
T ir es may be the least apprec iated and most abused pa rts of a moto r
vehicle. Tires are, however, one of the most important parts of a
veh icle, parti cularly conside ring the comparative ly small patch of
rubber on eac h tire that assu res that all- important co ntact between
you , your ve hicle and the road .
Ma inta in ing t he correct t ire pressu re, making s ure that your veh icle
and i ts tires do not have to carry more weight than they can safely
hand le, avoid ing damage from road ha za rds and reg ula rly inspect ing
tires for damage incl ud ing c uts, s lashes irregular wea r and overall
condi tion are the mos t important th ings that you can do to help avoi d
sudden tire fa ilure includ ing t read separation and blowouts .
Avoiding damage
If you have to drive over a curb or sim ilar obstacle, drive very s lowly
and as close as poss ible at a right angle to the cu rb .
Always keep chemicals including grease, oil , gasoline and bra ke fl uid
o ff the t ires .
Inspect the ti res regularly for damage (cuts, crac ks o r bl ist ers, e tc .).
Remove any foreign bodies embed ded in the trea ds.
Storing tires
M ar k tires when yo u remove t hem to indica te the d irect ion of rota ­
tion . This ens ures yo u to be able to mo unt them co rrectly whe n you
re insta ll them.
Wh en r emoved, t he wheels or tires s hould be sto red in a c ool, dry and
preferably da rk p lace. Sto
re tires in a ver tica l pos it ion if they a re not mounted on rims, in a
hor izonta l position if they are mo unted on r ims.
New tires
N ew tires have to be bro ken in~ & .
Th e tread dep th of new tires may v ary, ac cor ding to t he type an d
make of t ire and the tread pattern.
Hidden damage
Dama ge to t ires and rims is often not readi ly visible . If yo u notice
unusu al v ib rat ion o r the veh icle pulls to one sid e, t his may i ndicate
that one of the tires has been damaged. The tires must be c hecke d
i m medi ately by an a uthor ized A udi deale r or quali fied w or ksh op .
Unidirectional tires
A u nidirectional tire can be identified by arrows on the sidewall, that
point in the d irect io n the tire is des igned to rotate. Yo u m ust follow
t he s peci fied dire ction of ro tation . T his is nece ssary so th at t hese
tires can develop the ir optimum c haracter istics regarding gr ip, road
noise, we ar and hy dropl aning res istance. For more informa tion
~page 341 .
& WARNING
New tires or tires that are old , worn or damaged cannot provide
maximum control and braking ability.
• New tires tend to be slippery and must be broken in. To reduce
the risk of losing control, a collision and serious personal injuries, drive with special care for the first 350 miles (560 km) .
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure , including a blowout and sudden deflation ,
crashes and serious personal injuries. Have worn or damaged tires
replaced immediately. .,_

Inco rrect wheel al ignment
Incorrect wheel alignment can cause excessive tire wear, impairing
the safety of the vehicle . If tires show excessive wear, have the wheel
alignment checked by an authorized Audi dealer or qualified wo rk­
shop .
All Wheel Drive
Vehicles with quattro ® must always have tires of the same s ize,
constr uction and tread type . For details see~
page 257.
& WARNING
Sudden tire failure c an lead to loss of control , a cra sh and seriou s
personal injur y!
• Never drive a vehicle when the tread on any tire i s worn down
to the wear ind icators .
• Worn tire s are a s afety hazard, they do not grip w ell on wet
roads and increa se your risk of "h ydroplaning" and lo ss of control.
• Always keep chemical s that can cause tir e damage, su ch as
grea se , oil , gasoline and brake flu id away from tires .
• Tires age even if they ar e not b eing used and can fail suddenly ,
especially at high speeds. Tires that are more than 6 year s old can
only be used in an emergency and then with special care and at
lower speeds .
• Never mount u sed tir es on your vehicle if you are not sure of
their "previous history. " Old used tires m ay have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

Wheel bolts
Wheel b olts must al ways be tig hten ed to the correct
torque.
Th e design of whee l bo lts is matc hed to the facto ry installed rims. If
different r ims are fitted, the correct wheel bolts wi th t he r igh t lengt h
and correctly s haped bolt heads must be used . Thi s ensures that
w heels are fi tted secure ly and tha t the br ake system f unc tion s
correctly.
I n cert ain circumst ances, yo u may not us e wheel bolts from a
different veh icle -even if it is the same model=>
page 363.
& WARNING
Improperly tightened or maintained wheel bolts can become
loose causing lo ss of control, a collision and serious per sonal
injury .
• Always keep the wheel bolts and the thread s in the wheel hub s
clean so the wheel bolts can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while d riving if greased or oiled , even
if tightened to the specified torque.
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low , they can loo sen and come out when the
vehicle is moving. If the tightening torque is too high, th e wheel
Safety first
& WARNING (co ntinued )
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The speci fied tor que f or th e wheel bolts is 90 ft lb (1 2 0 Nm) wi th a
tolerance of ± 7,4 ft lb( ± 10 Nm). Torque wheel bolts diagonally.
After ch anging a wheel, the to rque mu st be checked a s so on as
poss ible with a torque w rench -prefe rab ly by an authorized Aud i
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is fa cto ry -equ ip ped wi th low aspec t ratio tires. These tire s
have been thorough ly tested and been selected specifically for your
mode l for the ir supe rb perfo rmance, roa d fee l an d han dling un der a
var iety of driv ing cond it ions. Ask your author ized Audi dea ler for
more deta ils.
Th e low a spect rat io of these tires is indica ted by a nu meral of
55 or
less
in the tire's size designation. The numeral represents the ratio of
t he t ire's s idewall heigh t in relat io n t o its t re ad wi dth expressed in
percentage. Conventiona l tires have a height/width ratio of 60 or
more .
The performance of low -aspect -ratio tires is particularly sen sitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and mainta ined. Tire pres­
s ure s should be checked at lea st once a month and always before a
long trip =>
page 313, "Checking tire pressure".
What you can do to avoid tire and rim damage
Low aspect ratio ti res can be damaged more easi ly by impact w ith
potholes, curbs, gull ies or ridges on the road, p articular ly if the tire is
underinflated. .,_
