Before you check anything in the engine com­
partment,
always r ead and heed all W ARN­
ING S ~ A in Working in the engine compart­
ment on page 213.
.. Read the brake fluid level from the brake
fluid reservoir ¢
fig. 192, ~ page 215,
fig . 188.
The brake fluid level must be be ­
tween the "MIN" and "MAX" markings.
The location of the brake fl uid reservoir can be
seen in the engine compartment illustration
¢page 215.
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
l ow the "MIN" mark, the brake wa rning/indi ­
cator light
1111 (U .S . models)/ . (Canadian
models) will come on
~ page 14. Do not con­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized Audi dealer or other quali­
f ied fac ility and the cause corrected . If the
b rake fluid level is too low, the brake warn ing/
i ndicator light w ill illuminate . Contact an au­
thor ized Audi dealer
imm ediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
hi gh, cor rosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerab ly and
decrease braking performance.
Therefore, the brake flu id must be changed
ev ery two ye ars. A lways use new b rake fluid
which confo rms to Federal Motor Vehicle
Standard "FMVSS
116 DO T 4".
The brake flu id rese rvoi r ca n be difficult to
r each, therefo re , we recommend that yo u
h ave the brake fl uid changed by you r autho r­
i zed
Audi de aler . Your dea le r has the correct
Checkin g and fillin g 223
tools, the right brake fl uid and the know -how
to do this for you .
A WARNING
-Brake flu id is poisonous. It must be stor­
ed only in the closed or iginal container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only b rake fluid tha t meets SA E
spe cificat ion
J 17 03 and conforms to
Federa l Moto r Ve hicl e Standard
116.
Always check with your authorized Audi
dealer to make sure yo u are using the
correct brake fluid. The correct type of
brake f luid is also ind icated on the
brake f luid reservoir .
- The brake fluid must be new. Heavy use
of the brakes ca n cause a vapor lock if
the brake fluid is left i n the system too
long. This can se riously affect the effi­
c iency of the b rakes as well as your
safety , T his could result in an accident.
(!) Note
Brake fluid will damage the paint of your
vehicle.
@) For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
r equired and the necessary expertise, we
r ecommend that you have th e brake flu id
changed by you r autho rized Aud i dea le r.
Battery
General information
Under normal operating cond itions, the bat­
tery in your Audi does not need any ma inte­
nance . With
high outside temperatu res or
lo ng da ily drives we recommend that you have
the e lectrolyte leve l che cked by a se rv ice fa­
c il ity. The ele ctroly te leve l should also be
chec ked each t ime the battery is cha rged

-Never mount used tires 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.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

Glossary of tire and loading terminology
Accessory weight means the comb ined weight (in excess of
those sta ndard items which may be rep laced)
of au toma tic transmission, power steer ing ,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not) .
Aspect ratio
means the rat io o f the height to the w idth of

typica l in those seasons . Aud i recommends
using winter tires during the winter
months . Low temperatures signif icant ly
dec rease the e lasticity of summer t ires,
which affects tract ion and brak ing ability.
If summer t ires are used i n very co ld tem ­
peratures, cracks ca n form o n the tread
bars , res ulting in perma nen t tire damage
that can cause loud driving noise and un­
bala nced ti re s. Audi i s not respon sible for
th is type of damage .
Cold tire inflation pressure
means the t ire p ress ure recommended by t he
vehicle manufacture r fo r a tire o f a des ignated

Extra load tire
means a t ire design to oper ate a t higher load s
and at higher inflation pressures than the cor­
responding standa rd tire . Extra load tires may
be identified as "XL", "x l", "EXTRA LOAD", o r
"RF" on the sidewal l.

Because tec hnical changes may be made to
ve hicl e equ ipment dur ing the model yea r, a l­
ways compare the tire s ize designation on the
tire pressure label on your vehicle with the
tires on your vehicle . Make s ure that the tire
size information on the vehicle label is the
same as the s ize of the t ires on the vehicle.
This is especially important if the vehicle be­
longs to someone else or you bought the veh i­
cle with different rims/tires or you bought the
veh icle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing sure that
load limits are not exceeded . Vehicle load in­
cludes everybody and everything in and on the
ve hicl e. These load limits are technically refer­
r ed to as the vehicle's G ross Vehicle We ight
Rating ("GVWR"). The Gross Ax le Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two axles .
The Gross Vehicle We ight Rating and the G
ross Ax le Weig ht Rating are listed on the
sa fety comp liance sticke r label lo cated on the
driver's side B-pillar . The tire pressu re labe l on
your A udi lists the maximum combined
weight of all of the occ upants and luggage o r
other cargo that the veh icle can carry. For the
location of the t ire pressure label ¢

A WARNING
-Overloading a vehicle can cause loss of ve-
h icle contro l, a crash or other accide nt, se­
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly a nd in­
crease the risk of a loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.

236 Tire s and whee ls
including a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passenge rs a lso
depends on making s ure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle. These
load limits are techn ically referred to as the
vehicle's
Gr oss Veh icl e W eight R ating
("GVWR").
The "GVWR" includes the weight of the basic
ve hicle, all factory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
i ntended to carry ("seating capacity") with a n
assumed weight of 150 lbs (68 kg) for each
passenger at a des ignated seat ing pos ition
and the tota l we ight of any luggage in the ve­
h icle.
The
Gro ss Axle Weight Rating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles .
The G ross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker labe l located on the
driver 's side B-p illar. Your A udi has 4 seating
positions, 2 in the front and 2 in the rear for
total seating capacity of 4. Each seating posi­
tion has a safety belt
9 page 133, Safety
belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the tota l weight of whatever is being car­
ried in the vehicle is limited. The more passen­
gers in the veh icle or passengers who are
heav ier than the standard weights assumed
mean that less weight can be carried as lug­
gage.
The tire pressure label on your Audi also lists
the maximum combined weight of all of the
occupants and luggage or other cargo that
the veh icle can carry . For the location of the
l abe l

A WARNING
Overloading a vehicle can cause loss of ve­
h icle contro l, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly 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
veh icle w ith in a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total lo ad be­
ing transpor ted does not make the veh i­
cle heavier than the vehicle's Gross Vehi ­
cle Weight Rating.

_& WARNING ,...__._
- Using incorrect or unmatched tires and/
or whee ls or improper tire and whee l
combinations can lead to loss of contro l,
co llision and serious persona l injury.
- Always use tires, rims and wheel bo lts
that meet the specifications of original
factory-installed tires or other combina­ t ions that have been spec ifically ap­
proved by the vehicle manufacturer.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds . Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds .
- Never mount used tires on your vehicle if
you are not su re of their "previous histo­
ry." Old used ti res may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss of vehicle control.
- All four wheels must be fitted with radia l
tires of the same type, size (rolling cir­ c u mference) and the same tread pattern.
Driving with different tires red uces veh i­
cle handling and can lead to a loss of
control.
Tire s an d wheel s 241
-If the replacement tire is not the same as
the t ires that are mounted on the veh icle
- for example with winter tires - only use
the replacement tire for a short per iod of
time and drive with extra care . Refit the
normal road whee l as soon as safely pos­
sible.
- Never drive faster than the max imum
speed for which the tires on you r vehicle
a re rated because tires that are dr iven
faster than thei r rated speed ca n fa il
suddenly .
- Ove rloading tires ca use heat build-up,
sudden tire fa ilure, including a blowou t
and sudden deflation and loss of cont ro l.
- Temperature grades apply to ti res that
are properly inflated and not over or un ­
derinf lated .
- F or technical reasons it is not always
possible to use whee ls from other
vehicles -in some cases not even whee ls
from the same veh icle mode l.
- If you install wheel trim discs on the ve ­
hicle wheels, make sure that the air flow
to the brakes is not b locked. Reduced air­
flow to the brakes can them to overheat, increas ing stopping d istances and caus­
ing a co llision.
- Run flat tires may only be used on
veh icles that were equipped with them
at the factory . The veh icle must have a
chassis designed for run flat tires . Incor­
rect use of ru n flat ti res can lead to vehi­
cle damage or accide nts. Che ck with an
author ized Audi dealer or tire spe cialist
to see if your vehicle can be eq uipped
with run flat tires . If run flat tires are
used, they must be installed on all four
wheels. Mixing tire types is not permit­
ted.
@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er veh icles. Th is can hold tr ue for wheels
of the same vehicle type. .,..
