224 Check ing and filling
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
¢ page 218.
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 w ill
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

248 Tires and wheels
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain 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 whee l bolts is matched to the
factory installed rims. If different rims are fit­
ted, 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 275.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision 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 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.
- Never use different wheels bolts on your
vehicle.
- Always maintain the correct tightening
torque for the wheel bolts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the veh i- cle
is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as possi­
ble with a torque wrench -preferably by an
authorized Audi dealer or qualified work­
shop.
Low aspect ratio tires
Your Audi is factory -equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road feel
and handling under a variety of driving condi­
t ions . Ask your authorized 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 s ize
designation . The numeral represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
tional tires have a height/w idth rat io of 60 or
more.
The performance of low-aspect-ratio tires is
particularly sensitive to improper inflation
pressure. 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 pres­
sures should be checked at least once a
month and always before a long trip
¢ page 237, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact with potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.

268 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.

-Always make sure the transm ission se­
lector lever (automatic transmiss ion) is
in "P" (Park position) or Neutral (manual
transmission) and the park brake is firm­
ly appl ied .
® For the sake of the environment
-Changing the eng ine settings w ill ad­
versely affect em ission levels. This is det­
rimental to the environment and increas­
es fuel consumption .
- Always observe env ironmental regula­
tions when d ispos ing of old engine oil,
used brake fluid, dirty engine coolant,
spent batter ies or worn out t ires.
- Undeployed airbag modules and p reten­
s ioners might be classified as Perchlo­
rate Material -special handling may ap ­
ply, see www.dtsc.ca .gov/hazardous­
waste/perch lorate . When the veh icle or
parts of the restraint system including
airbag modules safety belts with preten­
s ioners are scrapped, all applicable laws
and regulations must be observed. Your
authorized Audi dealer is familiar w ith
these requirements and we recommend
that you have your dealer perform this
serv ice for you .
