Natural leather
Aud i makes great eff orts to maintain the pro per ties,
n atu ra l look and feel of in ter ior leather.
General
We offer many different types of leather on our vehicles. Most are different types o f nappa leather, which has a smooth surface and
comes in various co lors.
The intens ity of the color de termi nes the vis ual c h aracteris tics and
appearance. If the surface of the leather has a typica l natural look ,
t hen t he leather is a nap pa lea ther tha t has been left in a re lati ve ly
natural condition. This leather offers particu lar ly good comfor t and
breathes well. Fine veins, closed grains, insect bites, skin folds, and
subt le variations in color remain visib le. These character istics
demonstrate that the material is natura l.
N at ura l n ap pa leather is not covere d by a col or fin is h. It is the refor e
more sensitive to soiling and wear, which is something you need to
co nside r if chi ld ren, a nim als o r othe r factors m ight prove to be
particularly hard on the leather.
By contrast, leather types that are covered by a colored finish layer
ar e mo re du rable. T his has a positive ef fect on the leather's resis ­
tance to wear and soiling in daily use. On the other hand, the typical
cha ract erist ics of natura l leather are barely or n ot appa ren t.
However, th is does not mean that the leather itself is of inferior
quali ty.

prevent the formation of harmful deposits, sometimes called
"sludge," that over time can lead to expensive repairs.
At the time of printing, engine oils available in the U .S . and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So
always be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal conditions where you drive. You can use oil with a viscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi­
tions .
However, if engine oil viscosity grade SAE 5W40 is not available, you
can also use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be
available everywhere when you need it, we strongly recommend
that you always carry with you an extra quart {liter) of oil that
expressly conforms to the VW 502 00 specification, in case you have
to top off the oil while on the road.
Only if the level of the oil is at or below the minimum mark on the
oil dipstick -and no oil that expressly conforms to Audi oil standard
VW 502 00 specifications is available -may you top off with a high
quality engine oil, preferably synthetic -based, that meets ACEA A3,
ACEA A5 or ACEA B5, API SL or ILSAC GF-3 specifications, but even
then, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40 .
However, during the entire time between oil change intervals, never top off with more than a total of 0
.5 qt/liter engine oil that does not
conform to Audi oil specification VW 502 00.
For more information about engine oil that has been approved for
your vehicle, please contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www.audiusa.com or www.audicanada.ca. Here you will also find a
current list of oils (manufacturers, brand names etc.) that conform
to Audi oil standard VW 502 00.
Changing the engine oil
The engine oil and oil filter must be changed according to the
mileage (kilometers) and time intervals specified in your vehicle 's
Warranty
& Maintenance booklet. Do not exceed these intervals -
harmful deposits from old engine oil can reduce engine perfor­
mance and can lead to expensive engine repairs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Advisor.
Under some circumstances the engine oil should even be changed
more frequently . Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and-go traffic conditions, or when you use your vehicle where
temperatures stay below freezing point for long periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not
a reason to change the oil more often than recommended .
Damage or malfunctions due to lack of maintenance
It is essential that you change your oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW 502 00 . Your New Vehicle Limited Warranty does not cover
damage or malfunctions due to failure to follow recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Warranty & Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in

the form of Service or Repair Orders that all schedu led maintenance
was performed in a time ly manner .•
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 provide effective lubrication and cool ing of internal
engine components , all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significantly over the life of the engine. Typically,
engines with a specified break -in period (see~
page 197) consume
more oil during the break-in period than they consume af ter oi l
consumption has stabi lized .
Unde r normal conditions, the rate of oil consumption depends on
the quality and viscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
conditions . Further factors are the amount of oil dilution from water
condensation or fuel residue and the oxidation level of the o il. As
any engine is subject to wear as mileage builds up, the oil consump ­
tio n may increase over time unt il rep lacement of worn components
may become necessary.
W ith all these variables coming into play, no standard rate of oil
consu mption can be estab lished or specified. There is no a lternative
to regular and frequent checking of the oil level, see
Note .
If the yellow engi ne oil level warning symbol in the instrume nt
cluster lights up, you should check the oil level as soon as
poss ible
with the oil dipstick~ page 229 . Top off the oil at your
earliest convenience~
page 230.
& WARNING
Before you che ck anything in the eng ine comp artment , alw ay s
read and heed all WARNINGS
~ & in "Working in the engine
c ompartment " on
page 22 5.
0 Note
Driving with an insufficie nt o il level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pressure warning displ ay ce,. is not an indi cat or of the oil
level . Do not rely on it. Instead , check the oil level in your engine at
regular interv als , prefe rably ea ch time you refuel , and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amoun ts of oil, we recommend that you consu lt your authorized
Audi dealer to have the cause of your concern proper ly diagnosed .
Keep in mind that the accura te m easuremen t of oil consumption
requires great care and may take some time . Your authorized Audi
dea ler has instructions about how to measu re oil consumption
accurately .•

0 Note
• Before winter 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 you 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
rized Audi dealers. Other types of antifreeze can significantly
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 fluid may adversely affect the
function and performance of your cooling system and could 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 . 175 Engine
compartment : 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 225.
Turn off the ignition.
Read the engine coolant level from the coolant expan­
sion tank==> fig. 175. 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 226.
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 30will 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.

vehicle at the time it was manufactured.
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants), you can adjust tire pressures to
those specified for normal vehicle load. Before operating the vehicle at maximum load, you must increase the tire pressures to those
specified for maximum vehicle load
=> &.
Bear in mind that the tire pressure monitoring system* can only
monitor the tire pressures you have stored. The system does not
recognize the load condition of your vehicle.
The effectiveness of the tire pressure monitoring system* will be impaired if you store normal load pressures but then operate the
vehicle at its maximum load=>&. See
the illustrat ion=>

either on driver's side B -pillar or inside the fuel filler flap (color of
the actual label and exact location on the vehicle will vary slightly).
Note that the following table is accurate at the time of going to
press and is subject to change . In the event of discrepancies, the tire
pressure label (on USA vehicles, the tire pressure label is loc ated on
driver's side B-pillar; on Canada vehicles, the tire pressure label is
