Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
te cts the engine from freezing in the winter .
The cooling system is sealed and generally re­
qu ires little attention .
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-based coolant additive G 13 antifreeze with
anticor ros ion add itives (50% for USA mode ls;
60% for Canadian mode ls). This mixtu re both
assures the ne cessa ry frost prote cti on and
p rotec ts metal components in the engine's
coo ling system from cor ros io n an d scaling. It
a lso raises the boiling point of the coolant.
D o not red uce the con cent ration o f th e coo l­
ant in the summe r by adding plain water .
The
proportion of coolant additive must be at least 50% but not more than 60%
to ma in­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant cou ld freeze and damage the veh i­
cle heating and eng ine cooling system .
For yea r-round driving, antifreeze is added at
the factory for temperatures down to:
- -3 1 °F (-35°C)USA
- -4 0 ° F ( - 40 °C) Canada.
A WARNING

220 Check ing and filling
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢
page 214 .
To obtain an accurate read ing, the eng ine
must be switched off .
The expans io n tank in you r vehicle is equipped
with an e lectr ic cool ant level sensor.
When the coolant level is too low, the warning light in the A uto-Check System ¢
page 18 will
b link until you add coo lant and the level has
been restored to no rm al. Even though the re is
an e lec tric coolant level sensor, we s till rec ­
ommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolan t loss, the cool ­
i ng system should be inspected immedia tely
by your authorized A udi dealer. It is not
enough merely to add coolant.
I n a
s e aled system, losses can occur only if
the boiling poin t of the coolant is excee ded as
a result of overheating.
A WARNING
The cooling system is unde r pressure and
can get ve ry hot. Reduce the risk of sca ld­
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 ve ry carefu lly in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap .
- To avoid being b urned, do not spill ant i­
freeze or coolant on t he exhaust system
or hot eng ine parts. Unde r certain condi­
tions, t he ethy lene g lycol in engine cool­
an t can ca tch fire.
(D Note
Do not ad d any type of radiator leak sea l­
ant to your veh icle's engine coo lant. Add­
i ng radiator repa ir fluid may adverse ly af­
fect the funct ion and performance of your
cooling system and could result in damage not cove red by your New Veh icle L imited

228 Tire s and wheel s
-Never mount used tires on yo ur 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 t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.

Please note that summer and winter tires
are designed for the cond itions that are
Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those sta ndard items which may be rep laced)
of au toma tic tra nsmission, power steer ing,
power brakes, power windows, power seats,
radio, and heater, to the extent that th ese
items are availab le as factory -installed equip­
ment (whether installed or not) .
Aspect ratio
means t he ratio of the he ight to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overall handling on dry pavement .
Bead
means the part of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead separation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typ
ica l in those seasons . Audi recommends
using winter tires during the winter
months . Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very co ld tem­
peratures, cracks ca n form on the tread
bars, res ulting in permanent tire damage
that can cause loud driving no ise and un­
balan ced t ires. Audi is not responsible for
th is type of damage .
Cold tire inflation pressure
means the tire p ressu re recommended by t he
vehicle manufacturer fo r a tire of a des igna ted
s iz e that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
t h e three hour period before the tire pressure
is measured or adjusted.
Curb weight
mea ns the we ight of a motor ve hicl e w ith
standard equipment including the max imum
capacity of fuel, oil, and coolant, air condi ­
tioning and additional weight of optiona l
equipment.
Extra load tire
me ans a t ire design to operate at higher loads
and at h igher inflation pressures than the cor­
responding standard tire . Extra load tires may
be identified as "XL", "x l" , "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR ")
means the lo ad -c a rry ing c apac ity of a s ingle
axle system , measured a t the tire-ground in­
terfaces.
Gross Vehicle Weight Rating ("GVWR ")
mea ns the maximum total loaded we ight of
t h e ve hicl e. .,.

.8, WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a veh icle 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 "hydrop lan ing" 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 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 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 s udden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .

24 4 T ire s and wheel s
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed rims. If differen t 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
secure ly and that the brake system funct ions
correctly .
In ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
i s the same model~
page 2 71.
_& WARNING
Improperly tig htened o r maintained whee l
bolts can become loose ca using loss of
contro 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
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed .
- Never use different wheels bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and com e out when the veh i­
cl e is moving. If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
@ Note
The spec ified torq ue fo r the wheel bo lts is
90 ft lbs. (120 Nm) wi th a toler ance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bo lts diagonally. After changing a wheel, the
torque m
ust be checked as soon as possi­
ble with a torque wrench -preferably by an
a uthori zed Audi dea ler or q ua lified work­
shop .
Low aspect ratio tires
Your Audi is factory -equ ipped w ith low aspect
ratio tires . T hese tires have been thoroughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a variety o f driv ing condi ­
t ions . As k your authorized A udi dealer for
more details .
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or l ess in the tire's s ize
designation. The numeral represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage . Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more .
The performance of low-a spect-r atio tire s is
pa rt icul arly s ens itive to imp ro per i nfl ation
pressure. It is therefore import ant that low
aspect ratio tires are inflated to the specified pre ssure and that the inflation pressure is
r e gularly checked and maintained . Tire pres­
sur es should be checked at l east once a
month and always before a long trip
~ page 233, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, c urbs, g ull ies
o r ridges on the road, pa rticul arly if the tire is
u nderinfla ted .
In orde r to minimize the occurrence of impact
damage to t he tires of your vehi cle, we recom­
mend tha t you observe the following preca u­
tions:
- Always ma inta in recommended inflation
pressu res. Check your tire pressure eve ry
2 ,000 miles (3,000 km) and add air if neces -
sary. ..,.

264 Emergency situations
fall from a lift if there is a change in ve­
hicle weight distribution and balance.
This might happen, for example, when
heavy components such as the engine
block or transmission are removed .
- When removing heavy components like
these, anchor vehicle to hoist or add cor­
responding weights to maintain the cen­
ter of gravity. Otherwise, the vehicle
might tilt or slip off the hoist, causing
serious personal injury.
(D Note
- Be aware of the following points before
lifting the vehicle:
-The vehicle should never be lifted or
jacked up from underneath the engine
oil pan, the transmission housing, the
front or rear axle or the body side
members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
inserted between the floor jack and
the lift points.
- Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity
of the hoist.
- Before driving over a workshop hoist,
ensure that there is sufficient clear­
ance between the hoist and low parts
of the vehicle.
