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=>

Changing the engine oil
We reco mmend tha t ha ve your oil chan ged by an auth o ­
ri zed Audi deal er or a qualified s erv ic e sta tion.
Before you check anything in the engine compartment, always read
and heed all WARNINGS=>
& in "Working in the engine compart­
ment" on
page 275.
Th e en gine oi l must be changed a ccording to the i nte rvals spe cifi ed i n
your Warranty
& Maintenance booklet. This is very important because
the lubricating prope rties of oil diminis h gradually during normal
veh icle use.
Under some circumstances the engine o il should be changed more
frequently . Change o il more often if yo u drive most ly sho rt dista nces,
operate the vehicle in dusty areas or under predom inant ly stop-and­
go tra ffic condi tions , or have your vehi cle where tempera tures rem ain
be low freezing for extended per iods.
Detergent ad ditives in the oi l will make fresh oil look dark after the
eng ine has bee n ru nning fo r a short t ime . This is normal a nd is not a
reason to change the oil mo re often than recommen ded .
B eca u se of the prob lem of pro per disposal, along with the s peci al
too ls and necessary expertise required, we strong ly recommend that
you have your o il changed by a n autho rized
Audi dealer or a qualified
serv ice stat io n.
If you choo se to change your oil yourself , please note the following
i m po rtant informat ion:
& WARNING
To reduce the risk of personal injury if you must change the engine
oil in your vehicle yourself :
• Wear eye protection.
• To reduce the risk of burns from hot engine oil, let the engine
cool down to the touch.

& WARNING (co ntinued )
• When removing the oil drain plug w ith your fingers , sta y as far
away as possible . Alway s keep your forearm parallel to the ground
to help p revent hot oil from running down your arm.
• Drain the oil into a container de signed 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 reach of chil­
dren.
• Continuous contact with u sed engine oil is harmful to your
skin. Always protect your skin by washing oil off thoroughly with
soap and water.

Safety first
Engine cooling system
Coolant
The engine coolant performs two functions: it keeps the
engi ne f rom over heat in g and it prote cts the engine fro m
free zing in the winter .
The coo ling system is sealed and generally requires little attention.
Th e cool ing sys tem h as been filled a t the f actory w ith a permanent
coo lant wh ic h does not need to be changed . The coolant consists of a
mi xtu re of water and the manufacturer 's glyco l-basedcoo lant add i­
t ive Gl2++ antifreeze w ith anticor ros ion addit ives (50% for USA
mode ls ; 60% for Ca nadian mode ls). This mixture both ass ures the
necessa ry frost protect ion and p rotects meta l components in the
engine's cooling system from corrosion and scaling. It also raises the
boiling poin t of the coo lant.
Do not red uce the concentrat io n of the coolant in t he summer by
adding p lain wate r. The proportion of coolant additive must be at
least 50 % but not more than 60 %
to maintain antifreeze protection
and coolin g efficiency. If the coolan t fros t pro tection is too low , the
coo la nt cou ld freeze and damage t he veh icle heat ing and engine
cooling system .
For year-ro und d riving, a ntifree ze is adde d at the fac to ry fo r tempe r­
atures down to:
• - 31°F(-3 5°C) USA
• -40°F ( -40°() Canada.
Yo u can mix the Gl2 ++ coo lant add itive with other additives (G12 + or
Gl2) . A lways check wi th yo ur auth o rized Audi dealer .
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS =>
& in "Working in the engine
compartment " on
page 275.

0 Note
• 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.

in. WARNING
• To reduce the risk of serious injury and vehicle damage.
-Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated
=> page 333, fig. 238 and
=> page 333, fig. 239.
- Failure to lift the vehicle at these points could cause the
vehicle to tilt or fall from a lift if there is a change in vehicle
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 corresponding weights to maintain the center of
gravity. Otherwise, the vehicle might tilt or slip off the hoist,
causing serious personal injury.
0 Note
• Be aware of the following points before lifting the vehicle :
-The vehicle should never be lifted or jacked up from under­
neath 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 clearance between the hoist and low parts of the
vehicle. •
