cold engine, the coo lant level should be be
tween the "min" and "max" markings. When
the engine is warm, the level may be s light ly
above the "max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus
tration
c:> page 218.
To obtain an accurate reading, the engine must be switched
off.
The expansion tank in you r vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check System
c:> page 15 will
i l lum ina te unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time.
Coolant los s
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
sea led system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise direction wh ile ap
plying light, downward pressure on the
top of the cap.
- To avoid be ing burned, do not spill ant i
freeze or coolant on the exhaust system
'
or hot engine parts. Under certain cond i
tions, the ethylene glycol in engine coo l
ant can catch fire.
(D Note
Do not add any type of radiator leak sea l
ant to your vehicle's engine coolant. Add i ng radiator repa ir fl uid may adverse ly af
fect the funct ion and performance of your
cooling system and could result in damage
not covered by your New Veh icle L imited
War ranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the eng ine com
partment,
always read and heed all W ARN

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 a lso damage importan t pa rts of the
ve hicle and can lead to s udden tire failure, in
cluding a blowout and sudden deflation that
can cause the veh icle to crash.
Your safety and that of yo ur 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 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 insta lled accessories, a full
tank of f ue l, oil, coolant and other fluids plus
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 total we ight of any l uggage in the ve
hi cle. If you tow a trailer, the weight of the
trailer 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 R ating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating a re listed on the
safety compliance sticker labe l located on the
driver's side B -pillar . Your A udi has 4 seating
positions, 2 in the front and 2 in the rear for
total seating capacity of 4. Each seating pos i
tion has a safety belt¢
page 128, Safety
belts .
Tire s an d wheel s 239
The fact that there is an upper limit to your
vehicle's Gross 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 w ho are
heavier than the standard we ights assumed
mean that less we ight can be ca rried as lug
gage.
The tire pressure label on your Aud i also lists
the maximum combined weight of a ll of the
occupants and luggage or other cargo that
the ve hicl e can carry . For t he locat ion of the
label¢
page 235, fig . 176.
.&_ 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 weight than your vehicle
was designed to carry wi ll 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 over load
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 -includ ing the weight of
a t railer hitch and the tongue we ight of a
loaded trailer - does not ma ke t he vehi
cle heavier than the vehicle's G ross Vehi
cle Weight Rating.

242 Tires and wheels
& 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 tires.
- Tires age even if they are not be ing 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 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 .

T he tires and rims are essential parts of the
vehicle 's design . The tires and rims approved
by Audi are spec ially matched to the charac
teristics of the vehicle and can make a major .,..
248 Tire s and whee ls
Where snow chains are mandatory oncer
tain roads, this normally also applies to ve
hicles with a ll-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory insta lled rims . If different rims are fit
ted, the correct wheel bolts with the r ight
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
r=> page 275.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop
er ly t ightened .
- Never grease or oil the wheel bo lts 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 whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue 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 w hen the veh i
cle is moving. If the tighteni ng torque is
too high, the whee l bolts and threads can be damaged and the whee
l can be
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torque whee l bolts diago
nally. After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author
i zed Audi dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-eq uipped w it h low aspect
ratio tires. These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and handling under a variety of driving condi
t ions . Ask your author ized A udi dealer for
more details.
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage. Conven
t iona l tires have a he ight/w idth ratio of 60 or
more .
The performance of low-aspect -ratio tires is
particularly sens iti ve to imp roper inflation
pre ssure. It is therefore important that low
a spect ratio tires ar e inflat ed to the specified
pre ssure and that the inflation pressure i s
r e gularly ch ecked and maintain ed. Tire pre s·
sure s should be checked at lea st once a
m onth and alw ays bef ore a long trip
r=> page 237, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be d amaged more
easily by impact with potholes, curbs, gull ies
or ridges on t he road, particularly if the tire is
u nd eri nflated.
