Before you check anything in the engine com­
partment,
a lwa ys read and heed all WARN­
ING S c:> .&.. in Working in the engine compart­
ment on page 179 .
~ Read the brake fluid level from the brake
fluid reservoir
c:> fig. 149, <=> page 181,
fig . 145.
The brake flu id level must be be­
tween the "MIN" and "MAX" markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the
left side <::;>
page 181 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads . This is not cause for alarm .
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (USA models: ., Canada models:
• will come on
<::;> page 13. Do not continue
to operate the vehicle . The complete brake
system should be thorough ly checked by an
author ized Audi dealer or qua lified workshop
and the cause corrected.
If the brake fluid lev­
e l is too low, the brake warning/indicator ligh t
will illuminate . Contact an authorized A ud i
dealer
immediately.
@ Tips
The brake f luid reservoir is located under­
neath the cover .
Checking and fillin g 189
Changing brake fluid
Have the brake fluid changed by on experi­
enced technician.
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also dec rease considerably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
ev ery two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "F MVSS 116 DOT 4".
The brake fluid reservo ir can be d iff icult to
reach, the refore, we recommend that you
have the brake fluid changed by your author­
i zed
Audi d ealer. Your dealer has t he correct
tools, the right brake fl uid and t he know-how
to do this for you .
A WARNING -.
-Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f luid. Observe these pre­
cautions:
- Use only brake fluid that meets SAE
spe cificat ion
J 1 7 03 and conforms to
Federa l Moto r Ve hicl e Standard 116.
Always check with yo ur authorized Audi
dealer to make sure yo u are using the
correct bra ke fluid. The correct type of
brake f luid is also indicated on the
brake f luid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
l ong . This can seriously affect the effi­
c iency of the brakes as well as your
safety. This cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

(D Note
Dr iving without va lve stem caps can cause
damage to the t ire va lves . To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secu re ly
mounted on the va lve .
@) For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption.
Tires and vehicle load limits
There are limits to the amount of load or
weight t hat any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in ­
cluding a blowout and sudden deflation that
can cause the ve hicle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making sure th at load limits are
no t exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle. These
load limits a re tech nica lly referred to as the
ve hicle's
Gross Veh icle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
ve hicle, all factory installed accessories, a full
tank of f uel, oil, coo lant and othe r fluids plus
max imum load. The maximum load includes
the number o f passenger s that the ve hicl e is
intended to carry ("se ating capacity") w it h an
assumed weig ht o f 150 lbs. (68 kg) for each
passenger at a designated seating position
and the tota l weight of any luggage in the ve­
h icle. If you tow a trailer, the weight of the
trailer hitch and the tong ue weight of the
Tire s an d wheel s 203
loaded tra ile r must be included as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating (" GAWR") is
the max imum load th at can be applied at each
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and t he
G ross Ax le Weig ht Ra ting are l iste d on the
s af ety comp liance s tic ke r la bel lo cated on the
driver's side 8 -pillar . Yo ur Audi has 5 seating
positions, 2 in the front and 3 in the rear fo r
total seating capacity of 5. Eac h seating posi ­
tion has a seat be lt

T he fac t that there is an upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is being car ­
ried in the vehicle ( includ ing the weight of a
trai ler hitch and the tongue weight of the
l oaded tra ile r) is lim ited . The more passen ­
gers in the vehicle or passe ngers w ho are
heavi er than the standard we ights assumed
mea n that less we ight can be ca rried as lug­
gage.

A WARNING
-=
Overloading a vehicle can cause loss of ve -
h icle cont ro l, a c rash or other accide nt, se ­
rious pe rsonal injury, and even death.
- Ca rrying more we ight than your vehicle
was des igned to carry wi ll prevent the
veh icle from handling pr oper ly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
ve hicle w it hi n a safe distance.
- Tires o n a vehicle that has been over load­
ed can fail s uddenly, incl uding a blowout
a nd sudden defla tion, causing loss of
con trol an d a crash . ..,.

206 Tires and whe els
& WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious persona l injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors .
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
yo ur risk of "hydroplan ing" and loss of
control.
- Always keep chemicals that can cause tire damage, such as grease, oil, gasoline and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly , especially at high
speeds . T ir es that are more t han 6 years
o ld can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used ti res on yo ur vehicle if
yo u are not sure of their "previous histo ­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .

driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this normally also applies to
veh icles with all wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled rims . If different rims are fit ­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model¢
page 239.
.&_ WARNING
Improperly tig htened or maintained wheel
bolts can become loose ca using loss of
cont ro l, a co llision and serious p ersona l in­
Jury.
- Always keep the wheel bolts and the
threads in t he wheel hubs clea n so the
wheel bolts can tu rn easily and be prop­
erly tigh tened.
- N ever grease or oil the wheel bo lts and
the threads in the wheel h ubs. They can
become loose w hile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- O nly use wheel bo lts that be long to the
rim being installed.
- N ever use different whee ls bolts on your
vehicle.
- Alw ays mai nta in the co rrec t tighte ning
tor que fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the veh i- cle is moving.
If the tig
hte ning torq ue is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the whee l bolts is
105 ft lbs. (140 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changing a wheel, the
torque must be checked as soon as poss i­
ble with a to rque wrenc h - preferab ly by an
a uthorized Aud i dea le r or qualified wor k­
shop.
Low aspect ratio tires
Your A udi is factory -eq uipped w it h low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
t ions . Ask your authorized Audi dealer for
more details .
The low aspect ratio of these tires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the tire's sidewall height in relation to its
t read width exp ressed in percentage. Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
pa rticularly sen sitive to improp er inflation
pre ssure. It i s therefor e important that low
a spe ct ratio tir es are inflated to the spe cified
pre ssure and that the inflation pre ssure i s
regula rly checked and mainta ined. Tire pre s­
sure s should be checked at lea st once a
month and always befo re a long trip
¢ page 201, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.

Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increas ingly more and more
difficult to replace vehicle lig ht bulbs s ince in
many cases, other parts of the car must first
be removed before you are able to get to the bulb.
This applies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment.
Sheet meta l and bulb holders can have sharp
edges that can cause serious cuts, parts must
be correct ly taken apart and then properly put
back together to he lp prevent breakage of
parts and long term damage from water that
can enter housings that have not been proper­
ly resealed.
For your safety, we recommend that you have
your authori zed Audi dea ler replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamps (Xenon lights ):
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light are identified by
the high voltage st icker.
A WARNING "--
Changing Xenon lamps without the neces-
sary equipment can cause serious persona l
injury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
- On veh icles equipped with gas discharge
bulbs (Xenon light) life-threatening inju­
ries can result from improper handling of
the high-voltage portions of such lamps!
- Only your authorized Audi dealer or qualified workshop should change the
bu lbs in gas discharge lamps. There are
pa rts with sharp edges on the openings
and on the bulb holders that can cause
serious cuts. If you are uncertain about
what to do, have the work performed by
an authorized Audi dealer or qualified
workshop. Serious personal injury may
result from improperly performed work.
@ Tips
-If you still prefer to replace the light
bulbs yourself, be aware that the engine ..,.
