@ Tips
The brake fluid rese rvoir is located unde r­
neath the cover.
Changing brake fluid
Hove the broke fluid changed by on experi­
enced technician .
Brake fluid absorbs moistu re from the a ir. If
the water content in the brake fluid is too
hi gh , corrosion in the b rake system may resul t
after a per iod of t ime . The bo iling po int of t he
b rake fluid w ill also decrease considerably and
decrease braking performance.
Therefore, the brake flu id must be changed
e ver y two year s. Always use new b rake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake flu id rese rvoi r ca n be difficult to
r eac h, therefore , we recommend th at yo u
h ave the brake f luid changed by yo ur autho r­
ized
Audi dealer . Your deale r has the correct
too ls, the right brake fluid and the know -how
to do th is for you.
A WARNING
- Brake fluid is po isonous . It must be stor­
ed only in the closed orig inal container
out of the reac h of children!
- Brake fa ilure can result from old or inap­
propr iate brake fluid . Observe these pre­
caut ions:
- Use on ly bra ke fluid that meets SAE
specification
J 1 7 03 and conforms to
Checkin g and fillin g 217
Federa l Moto r Ve hicle Standard 1 16 .
Always check with your authorized Audi
dealer to make sure you are using the correct brake fluid . The correct type of
brake flu id is also ind icated on the
brake f luid rese rvoir .
- The brake fluid must be new . Heavy use
of the brakes ca n cause a vapo r lock if
the b rake fluid is left i n the system too
l ong. This can se riou sly affect the effi­
c iency of the brakes as well as your
safe ty . T his co uld resu lt in an accident.

230 Tire s and wheel s
@ For the sa ke 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 that any vehicle and any t ire can carry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not only lead to loss of vehicle control, but can also damage important pa rts of the
vehicle and can lead to s udden tire failure, in­
cluding 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 limi ts are
not exceeded . Vehicle load includes everybody
and everything in and on the vehicle. These
load limits are technica lly referred to as the
vehicle's
Gross Veh icle We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of f uel, oi l, coo lant and other fluids pl us
maximum load. The maximum load includes
the number of passengers that the vehicle is intended to carry ("seating capacity") with an
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 l uggage in the ve­
h icle. If you tow a trailer, the weight o f the
trai ler hitch and the tong ue weight of the
loaded trailer must be included as part of the
vehicle load.
The
Gro ss Axl e W eight 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 Weigh t Rating are listed on the
safety compliance sticker labe l located on the
driver's side B-pi llar . Audi has 4 seati ng posi­
tions, 2 in the front and 2 in the rear for tota l
seating capacity of 4 . Each seating position
has a seat belt¢
page 129, Safety belts.
T he fact 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
trailer hitch and the tongue weight of the
loaded tra iler) is lim ited . The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mea n tha t less we ight can be carried as lug­
gage.
T he t ire pressure label on your Aud i also lists
the max imum combined weig ht of a ll of the
occupants and luggage or other cargo that
the vehi cle can carry . For the location of the
label¢
page 226, fig. 185.
.&, 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.
- Ca rrying more weight than your vehicle
was des igned to carry wi ll prevent the
vehicle 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 load be­
ing transported -including the weight of
a trailer hitch and the tongue we ight of a
loaded trailer - does not ma ke the vehi­
cle heavier than the vehicle's G ross Vehi­
cle Weight Rating.

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal 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
your risk of "hydroplaning" 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 . Tir es 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 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.
