The expansion tank in your vehicle is equipped
with an electric coolant level sensor
r::!) page 14.
We still recommend you check the coolant level
from time to time .
Coolant lo ss
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
author iz ed Audi dealer. It is not enough merely
to add coolant.
In a
s e a led system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheat ing.
A WARNING
- The cooling system is under pressure. Do
not open the cap of the coolant expans ion
tank when the engine is hot. You risk being
sca lded.
-
- The coolant add itive, and therefore the cool­
ant itself, is hazardous to health. Keep the
c oolant additive in the or igina l co ntainer out
of the re ach of children.
It is a poison haz­
ard.
Ch eck ing and fillin g
(D Note
Do not add any type of radiator leak sea lant
to your vehicle's engine coolant . Add ing radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Veh icle Limited Warranty.
Adding coolant

We recommend using only coolant add it ive Gl2+
+, G l3
or in an emergency Gl2 +. Do not use a
different additive. In an emergency use pla in wa­
ter unt il you ca n get the correct add itive and can
restore the co rrect ratio . This should be done as
soon as possib le .
If you have los t a considerab le amount of cool­
ant, then you shou ld add cold antifreeze and cold
water only when the engine is co ld .
Always use
new engine coo lant when refilling .
Do not fill coolant above the "max" mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the eng ine becomes
hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps .
- Turn off the engine and allow it to cool
down .
- Protect your face, hands and arms from escaping fluid and steam by covering the
cap with a large, thick rag.
163

Checking and filling
-Turn the cap slowly and very carefully in a
counter-clockwise direction while applying
light, downward pressure on the top of
the cap .
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or hot engine parts. Under certain condi ­
tions, the ethylene glycol in engine cool­
ant can catch fire .
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out of the reach of children .
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison".
CD Note
-Coolant pollutes the environment and could
cause an engine fire . Excess coolant will be
forced out through the pressure relief valve
in the cap when the engine becomes hot.
-If, in an emergency, only water can be add­
ed, the correct ratio between water and an­
tifreeze
¢ page 161 must be restored as
soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulations.
Brake fluid
Have the brake fluid changed by an experienced
technician.
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after a peri­
od of time. The boiling point of the brake fluid
will also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed
every
two years.
Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4".
164
Brake fluid is replaced according to the Audi
maintenance service schedule . Your authorized
Audi dealer is equipped with the necessary spe­
cial tools and replacement parts, has the neces­
sary expertise, and can dispose of the used fluid .
A WARNING
-Brake fluid is poisonous . It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old or inappro­ priate brake fluid. Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard
116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid .
The correct type of brake fluid is also indi­ cated on the brake fluid 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 long.
This can seriously affect the efficiency
of
the brakes as well as your safety . This
could result in an accident.
CD Note
Brake fluid will damage the paint of your vehi­
cle.
@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as well as the special tools re­
quired and the necessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer.
Battery
General information '
Your vehicle is equipped with a special battery, an
ACM battery . This battery is located in the lug­
gage compartment and must be replaced with an
original equipment battery. Under normal oper­
ating conditions, the battery is
maintenance-
free. ..,_

Tires and wheels
Cold tire infl ation pre ssure
means the tire pressure recom ­
mended by the vehicle man ufac­
turer for a tire of a designated
size that has not been driven fo r
more than a couple of miles (kilo­
meters) at low speeds in the three
hour period before the tire pres­
sure is measured or adjusted .
Curb weight
means the weight of a motor ve­
hicle with standard equipment in­
cluding the maximum capacity of
fuel, oil, and coolant, air condi­
tioning and additiona l weight of
optional equipment.
E x tra load tire
means a tire designed to operate
at higher loads and at higher in­
flation pressures than the corre­ sponding standard tire. Extra load
tires my be identified as "XL",
"xl ", "EXTRA LOAD", or "RF" on
the sidewall.
Gross Axle Weight Rating ("GAWR" )
means the load-carrying capacity
of a single axle system, measured
at the tire -ground interfaces.
1 72
Gross Vehicle Weight Rating
("GVWR")
means the maximum total loaded
weight of the vehicle.
Groove
means the space between two ad­
jacent tread ribs.
Load rating (code )
means the maximum load that a
tire is rated to carry for a given in­
flation pressure . You may not find
this information on all tires be­
cause it is not required by law .
Maximum load rating
means the load rating for a tire at
the maximum permissible infla­
tion pressure for that tire .
Maximum loaded vehicle
weight
means the sum of :
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity weight, and
(d) Production options weight
Ma ximum (permissible )
inflation pressure
means the maximum cold infla­
tion pressure to which a tire may be inflated. A lso called "maxi-
mum inflation pressure ." .,.

technically referred to as the vehi­
cle's
Gross Vehicle We ight Rating
("GVWR") .
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci ­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar. Your Audi
has 2 seating positions . Each
seating position has a safety belt
¢ page 95, Safety belts.
The fact that there is an upper
limit to your vehicle's Gross Vehi ­
cle Weight Rating means that the
total weight of whatever is being
Tires and wheels
carried in the vehicle is limited.
The more passengers in the vehi­
cle or passengers who are heavier
than the standard weights as­
sumed mean that less weight can
be carried as luggage.
The tire pressure label on your
Audi also lists the maximum com ­
bined weight of all of the occu­
pants and luggage or other cargo
that the vehicle can carry. For the location of the label¢
page 176,
fig. 147.
A WARNING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and in­
crease the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud­
denly, including a blowout and •

CD Note
-Remove snow chains before driving on roads
not covered with snow to avoid damaging
tires and wearing the snow chains down un­ necessarily.
- Snow chains, which come into direct contact
with the wheel rim, can scratch or damage
it. Therefore, make sure that the snow
chains are suitably covered . Check the posi­
tion of the snow chains after driving a few
yards and correct if necessary. Follow the in­
structions from the snow chain manufactur­
er when doing so.
(j) Tips
Where snow chains are mandatory on certain
roads, this normally also applies to vehicles
with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the fac­
tory installed rims. If different rims are fitted,
the correct wheel bolts with the right length and
correctly shaped bolt heads must be used. This
ensures that wheels are fitted 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 217.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of con­
trol, a collision and serious personal injury.
-
- Always keep the wheel bolts and the threads
in the wheel hubs 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 driving if greased or oiled, even
if tightened to the specified torque.
- Only use wheel bolts that belong to the rim
being installed.
Tires and wheels
- Never use different wheels bolts on your ve­
hicle.
- Always maintain the correct tightening tor­
que 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 loosen and
come out when the vehicle is moving. If the
tightening torque is too high, the wheel bolts and threads can be damaged and the
wheel can become loose.
CD Note
The specified torque for the wheel bolts is 90
ft lb (120 Nm) with a tolerance of± 7 .4 ft lb
(± 10 Nm) . Torque wheel bolts diagonally. Af­
ter changing a wheel, the torque must be
checked as soon as possible with a torque
wrench -preferably by an authorized Audi
dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ra­
tio tires. These tires have been thoroughly tested
and been selected specifically for your model for
their superb performance, road feel and handling under a variety of driving conditions . Ask your au­
thorized Audi dealer for more details.
The low aspect ratio of these tires is indicated by
a numeral of
55 or less in the tire's size designa­
tion. The numeral represents the ratio of the
tire's sidewall height in relation to its tread width
expressed in percentage. Conventional tires have
a height/width ratio of 60 or more.
The performance of low-aspect-ratio tires is par­
ticularly sensitive to improper inflation pres­
sure. It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should be checked at least once a month and always
before a long trip
