0 Note
Dr iv ing with an insufficient oil level is likely to cause severe damage
to the engine .
[ i ] Tips
• The oil pressure warning display~ is not an indicator of the oil
level. Do not rely on it. Instead , check the oil level in your engine at
regular intervals, preferably each time you refuel, and always
before going on a long trip .
• If you have the impression your engine consumes excessive
amounts of oil, we recommend that you consult an authorized Audi
dealer to have the cause of your concern properly diagnosed. Keep in
m ind that the accurate measurement of o il consumption requires
great care and may take some time. An authorized Audi dealer has
instructions about how to measure oil consumption accurately .•
Checking the engine oil level
Fig. 206 MMI Display:
Oil leve l ind icator
Read oil level
-Park your vehicle so that it is horizontally level.
- Shut the engine off when it is at operating temperature.
Vehicle OP-eration
-Wait approx . two minutes.
- Select: Function button
[CAR]> Oil level.
- Read the oil level in the MMI* Display => fig. 206. Add
engine oil if the bar of the oil level indicator is near "Min"
=>
page 279
Depending on the way the vehicle is driven and the operating condi­
tions, oil consumpt ion can be up to a 1/2 quart per 600 mi les (0.5
liter per 1,000 km). Consumption may be higher within the first
3,000 miles (5,000 km) .
[ i ] Tips
Th e oil level indicator in the MMI* Display is on ly an information
display.
If the oi l level is too low, a m inimum o il warning appears in
the instrument cluster. Add oil=>
page 2 79. If the hood has been
opened, the current oil level is shown in the instrument cluster the
next time the ignition is switched on .•

• Before w inter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if yo u live in a region where
the winter is extremely cold.
If necessary, increase the proportion of
coolant additive to 60% .
• When adding coolant additive to your cooling system, remember :
- We recommend using only coolant additive G12++ (check the
label) for your vehicle. This coolant additive is available at autho­
r iz ed Audi dealers. Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle 's
engine coolant. Adding radiator repair flu id may adversely affect the
function and performance of your cooling system and cou ld result in
damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant Level
The engine coolant level can be checked with a quick
glance.
Fig. 208 Engine
co mpartment : Coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS~ & in "Working in
the engine compartment" on
page 275.
-Turn off the ignition.
- Read the engine coolant level from the coolant expansion
tank~ fig. 208 . With a cold engine, the coolant level
should be between the "MIN" and "MAX" markings. When
the engine is warm, the level may be slightly above the
"MAX" marking.
The locat io n of the coolant expansion tank can be seen in the engine
compartment illustration~
page 276.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped with an electric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check
System =>
page 34 will blink until you add coolant and the level has
been resto red to normal. Even though there is an electric coolant
level sensor, we still recommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling system. In the event of
coolant loss, the cooling system should be inspected immediately by
your authorized Audi dealer. It is not enough merely to add coolant.
In a
sealed system, losses can occur only if the boiling point of the
coo lant is exceeded as a result of overheating .
& 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.

& WARNING (conti nu ed )
• Tire s age even if they are not being used and can fail suddenly ,
especially at high speeds . Tires that are more than 6 year s old can
only be used in an emergency and then with special care and at low
s peed .
Glossary of tire and loading terminology
Accessory weight
means the combined we ight (in excess of those sta nda rd items which
may be rep lace d) of automatic transmission, power steering, power
bra kes, powe r w indows , power seats, radio, and heater, to the extent

Tire pressure
Incorrect tire pressure causes premature wea r a nd can cause sudden
t ire blow-out. For this reason, ti re p ressure must be checked at least
once a month ~
page 297.
Driving style
Driving fast around curves, heavy acce le ra tion and hard brak ing
increase tire wear .
Rotating tires for more even wear
For all four tires on your veh icle to have the same service life, we
re commend that the fron t and re a r tires are rotate d according to the
tire manufact urer's suggested tire rotation interva ls . Please
remember the fo llow ing:
• Tir e rotat ion inte rvals may differ from t he ve hicl e service intervals
outlined in your Maintenance and War ranty Booklet .
• T he longer one tire is used in one location on the veh icle, the more
it wears at certa in points; therefore, we recommend that you follow
t he t ire m anufac ture r's suggested tire rotation in terva ls.
• V ehicles with front-whee l drive expe rience mo re tread wea r on t he
fron t wheels compa red to all-whee l drive (quattro
® ).
• Please rotate tires as s hown ~fig. 215.
• Extra care must be taken when rotating d irection-specific tires
~ page 321.
Wheel balancing
The w heels on new vehicles are balanced. Howeve r, va rious sit uat io ns
dur ing eve ryday dr iv ing can cause them to become unbalanced,
re su lt ing in v ibr ations yo u can usually fee l throug h the steering
wheel.
Unbalanced wheels must be rebalanced to avoid excessive wea r on
steeri ng, suspension and t ires . A wheel must also be rebalanced
w hen a new tire is installed.
Incorrect wheel alignment
Incorrec t whee l alignment can ca use excessive tire wear, impai ring
t he sa fety of the veh icle . If tires show excess ive wear, have the wheel
alignment checked by an authorized A udi dealer or qualified wo rk­
shop .
All wheel drive
Vehicles w ith q uattro ® must always have ti res of the same size,
const ructio n and trea d type. For details see~
page 242 .
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wea r ind icato rs.
• Worn tire s are a safety hazard, they do not grip well on wet
roads and in crease your risk of "hydroplaning" and lo ss 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 tire s on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

wheels are fitted secure ly and that the brake system func tions
cor rectly.
I n certa in circumsta nces, yo u may not use wheel bo lts from a
different vehicle -even if it is the same model =>
page 342 .
& WARNING
Improperly tightened or maintained wheel bolts can become
loose causing loss of control, 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 .
• 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 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.
0 Note
The specified torque for the wheel bolts is 90 ft lbs. (120 Nm) wit h a
tol eran ce o f± 7,4 ft lbs.( ± 10 Nm ). Tor qu e wheel bolts di ag on ally.
After chang ing a wheel, the to rque must be checked as soon as
p ossib le wi th a tor qu e wrench - prefer ably by an authorized Audi
dealer or qualified wo rkshop .•
Safety first
Low aspect ratio tires
Your Audi is factory-equipped with low aspect rat io tires. These tires
h ave bee n t horo ugh ly te st ed a nd bee n sele cted spe cifica lly for your
mode l for their supe rb performance, road fee l and hand ling u nder a
v ariety o f dr iv ing co ndi tio ns . Ask your author ized A udi d ealer for
more deta ils.
Th e low as pect rat io of these tires is indicated by a numera l o f
55 or
less
in t he ti re 's s ize des ig nation. The nu meral represen ts the ratio o f
the t ire's si dewall height in relat io n to its tread wi dth expressed in
per ce nta ge. Conve ntiona l t ires h ave a heigh t/w idt h 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 pre s­
sures should be checked at least once a month and always before a
long trip~ pag e 297, "Ch ecking tire pre ss ur e".
What you can do to avoid tire and rim damage
Low as pect ratio t ires ca n be damaged more easi ly by impact w ith
potholes, curbs, gullies or ridges on the road, pa rtic ularly if t he tire is
unde rinflated.
I n order to minim ize the occurrence of impact damage to the t ires of
your vehicle, we re co mmend that y ou o bserve the f ollowin g pre ca u­
tions :
• Always maintai n recommen ded in flation p ressures. Chec k your
tire pressu re e very 2,0 00 m ile s (3,0 00 km) an d add air if n ecess ary .
• D rive ca refu lly on roads with potholes, deep gulli es o r ridges. The
impact from d riving thro ugh or over such obs tacles can damage your
tires. Im pact w it h a cu rb may also cause damage to your tires .
• After a ny impact , immediately inspect you r tir es o r have t hem
inspected by the nea rest author ized Aud i dealer . Replace a damage d
t ire as soon as possib le. _.,
