Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to prov ide effect ive lubrication and cool ing of in ternal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumption varies from engine to engine
and may change significantly over the life of the engine . Typically,
eng ines wi th a specified break -in period
(see ~ page 243) consume
more oil during the break -in period than they consume after oi l
consumption has stabi lized .
Under norma l condit ions, the rate of o il consumption depends on
the quality and viscosity of the oil, the RPM (revo lutions per minute)
at whic h the engine is operated, t he amb ient te mperature and road
conditions. Further factors are the amount of oil dilution from water
condensatio n or fuel residue and t he oxidation level of the o il. As
any engine is subject to wear as mileage builds up, the oil consump ­
t ion may increase over time until rep laceme nt of worn components
may become necessary .
With all these variables coming into play, no standard rate of oil consu mption can be estab lished or specified. T here is no a lternative
to regu lar and frequent checking of the oil level, see
Note .
If the yellow eng ine o il level warni ng symbol in the instrument
cluster ~ lights up, you should check the oil level as soon as
possible
with the oil dipstick ~ page 277 . Top off the o il at your
earl iest
convenience~ page 278.
& WARNING
Bef ore you che ck anything in the eng ine comp artment , alway s
read and heed all WARNINGS
~ & in "Working in the engine
c ompartment " on
page 27 3.
0 Note
Driving with an insuff ic ient oil level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pres sure warning displ ay "e:7: is n ot an indi cator of the oil
level . Do not rel y on it. Instead, check the oil level in your engine at
regular inter vals, preferably ea ch time you refuel , and al way s before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oi l, we reco mmend that you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that t he accurate measurement of oil consumptio n requ ires great
care and may take some time. Your Audi dealer has instructions
about how t o measure oil cons umpt ion accurately. •

Changing the engine oil
We recommend that have your oil changed by an autho ­
rized Audi dealer or a qualified service station.
Before you check anything in the engine compartment, always read
and heed all WARNINGS =>
& in "Working in the engine compart ­
ment" on
page 273.
The engine oil must be changed according to the intervals specified
in your Maintenance
& Warranty booklet. This is very important
because the lubricating properties of oil diminish gradually during
normal vehicle use.

Under some circumstances the engine oi l should be changed more
frequen tly . Change oil m ore often if you drive most ly shor t
distances, operate the vehicle in dusty areas or under predom i­
n ant ly stop -and -go traffic conditions , or have yo ur vehicle whe re
temperatures remain below freezing for extended periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has bee n run nin g fo r a sh ort time. This is nor mal and is not
a reason to change the oi l more often than recommended .
Beca use of the proble m of p roper d isposal, along wi th the s pec ia l
tools and necessary expertise required, we strongly recommend
t hat yo u have your oi l ch anged by an authorized
Audi dealer or a
qua lified serv ice stat ion .
If you choose to change your o il yourself , please note the follow ing
i mportan t informatio n:
& WARNING
To reduce the risk of personal injury if you must change the engine
oil in your vehicle yourself :
• Wear eye prote ction .
• To reduce the risk of burns from hot engine oil , let the engine
c ool down to the touch .
• When removing the oil drain plug with your fingers, stay as far
away as po ssible . Always keep your forearm parallel to the ground
to help prevent hot oil from running down your arm.
• Drain the oil into a container designed for this purpose , one
large enough to hold at least the total amount of oil in your engine.
• Engine oil is poisonous . Keep it well out of the rea ch of ch ildren .
• Continuous contact with used engine oil is harmful to your
skin . Always prote ct your skin by washing oil off thoroughly with
soap and water.

Engine cooling system
Coolant
T he engine coolan t performs two fun ctions: it keeps the
engine from overhe ating and it pr otec ts the engine from
f reez ing i n th e win ter.
Th e cooling system is sea led and general ly requires l itt le attention.
T he coo ling system has been fi lled at the factory with a permanent
coo la nt which does not need to be c hange d. The c oolan t consis ts of
a mixture of water and the manufacturer's glycol -based coolant
additive G12 + an tifreeze wi th anticorros io n add itives (50% for USA
models; 60% for Canadian models). This mixture both assures the
necessary frost protection and protects me tal components in the
engine's cool ing system from corrosion and scaling . It also raises
the boiling poi nt of the coolant .
Do n ot reduce t he co ncentration o f the coolan t in the su mmer by
adding plain water .
The proportion of coolant additive must be at .,_

___ C_ h_ e_c _k _ i_n ~g _ a_n_ d_ f_il _li _n_ g~--------------------------------------------
-Read the engine coolant level in the open coolant expan­
sion
tank => fig. 211. 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 location of the coolant expansion tank can be seen in the
engine compartment
illustration=> page 275 .
To obtain an accurate reading, the engine must be sw itched 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 31 will blink until you add coolant and the
level has been restored 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 cooling system . In the event
of coolant loss, the cooling system should be inspected immedi­
ately 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
coolant 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.
• Protect your face, hands and arms from escaping fluid and
steam by covering the cap with a large, thick rag.
& WARNING (continued)
• 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 antifreeze or coolant on the
exhaust system or hot engine parts. Under certain conditions, the
ethylene glycol in engine coolant can catch fire.
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coolant. Adding radiator repair fluid may adversely affect the func ­
tion and performance of your cooling system and could result in damage not covered by your New Vehicle Limited Warranty. •
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compartment,
always read and heed all WARNINGS => & in "Working in
the engine compartment" on
page 273.
-Turn off the engine.
-Let the engine cool down.
-Place a thick rag over the coolant expansion tank
=> page 281 , fig. 211 and carefully twist the cap counter­
clockwise
=> & .
-Add coolant.
-Twist the cap on again tightly.
Replacement engine coolant must conform to exact spec ifications
=> page 280, "Coolant". If in an emergency coolant additive G12 + is .,,

crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• 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
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­

means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
&, WARNING (continued)
• Never mount used tires 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.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage.
•
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period

& 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 wear indicators .
• Especially in wet and slick driving situations , a preferably large
profile depth of the tires is necessary , and an approximately
similar profile depth of the front and rear axle tires.
• The diminished driving safety , caused by too small of a tire
profile, is negatively perceivable especially in handling , in danger
of hydroplaning when driving through deep puddles and ponds,
when driving around curves , and in braking behavior.
• 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 chem icals 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 .

Tires and wheels 1111
----------------
W For the sake of the environment
Use summer tires when weather conditions permit. They are
quieter, do not wear as quickly and reduce fuel consumption. •
Snow chains
Snow chains may be fitted only to the front wheels, and only to
certain tire sizes. Ask your authorized Audi dealer on which tire
sizes snow chains can be used.
If you are going to use snow chains, then you must install them on
the front wheels at least.
The snow chains must have low-profile links and must not be thicker
than 0.53 inch (13.5 mm), including the lock.
Remove wheel center covers and trim discs before putting snow
chains on your
vehicle => 0. For safety reasons cover caps must
then be fitted over the wheel bolts. These are available from autho­
rized Audi dealers.
& WARNING
Using the wrong snow chains for your vehicle or installing them
incorrectly can increase the risk of loss of control leading to
serious personal injury.
• Snow chains are available in different sizes. Always make sure
to follow the instructions provided by the snow chain manufac­
turer.
• When driving with snow chains never drive faster than the
speed permitted for your specific snow chains.
• Always observe local regulations .
0 Note
• Remove snow chains before driving on roads not covered with
snow to avoid damaging tires and wearing the snow chains down
u n 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.
[ i] 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 factory 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 348.
& 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.
