& WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit. Other
road users must not be put at risk - you may cau se an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often . This could
cause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake . This may cause the brakes to overheat ,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
passing through water , driving in heavy rain or after washing the
& WARNING (co ntinued )
vehicle, the effectiveness of the brakes can be reduced . In winter,
ice can ac cumulate on the brake pads, linings, dis cs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations.
• Driving for an extended period of time on salt-covered roads
without u sing your brakes can also affect braking efficiency . Clean
off accumulated salt coating from b rake discs and pads with a few
careful brake applic ations.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes i s not obstructed .
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping di stance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop.

& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working, for example when towing
your vehicle , or because the brake booster has somehow been
damaged, the brake pedal mu st be pressed considerably harder to
make up for the lack of booster assistance. •

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:

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 .•

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.
