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 279) consume
more oil during the break-in period than they consume after 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.
With 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 313 . Top off the oil at your
earliest convenience~
page 314.
& 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 309 .
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 oi l, we recommend tha t you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that the accurate measureme nt of oil consumption requires great
care and may take some time. Your Audi dealer has instructions
about how to measure oil consumption accurately. •

Maintaining proper tire pressure is one of the most important
things you can do to help avoid sudden tire failure. Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying. Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load-carrying capacities approved for your vehicle.
The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
•
Tire pressure generally refers to the amount of air in a tire that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents . Tire pressure is measured in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSI). Tire pressure is based in part on the vehicle's design and
load limit -the greatest amount of weight that the vehicle can carry
safely and the tire size. The proper tire pressure is frequently
referred to as the "recommended cold tire inflation pressure ." Air in
the tires expands when the tire heats up because of internal friction
when it flexes in use. The tire pressure is higher when the tire has
warmed up than when it is "cold." It is the inflation pressure in a
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure " recommendations .
The tires would then be underinflated and could fail suddenly. On
USA vehicles, the tire pressure label is located on the driver's
side 8-pillar . On Canada vehicles, the tire pressure label is located
either on the driver's side 8 -pillar or inside the fuel filler flap . The tire

pressure label lists the recommended cold tire inflation pressures
for the vehicle at its maximum capacity weight and tires that were
on your 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 effec tiveness of the tire pressure mon itoring system* will be
impaired if you store normal load pressures but then operate the
vehicle at its maximum load=>&. See the

& WARNING (continued)
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly
causing loss of control and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating.
& WARNING
• Incorrect tire pressures and/or underinflation can lead to a
serious or fatal accident.
• Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the handling of the vehicle.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control. •
Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
either on driver's side 8-pillar or inside the fuel filler flap.
The recommended tire pressures are on the tire pressure label and
in the table~
page 330, "Cold tire inflation pressure".This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of miles (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal friction as it flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold ." It
is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Cold tire inflation
pressure" recommendations~
page 330. The tires would then be
underinflated and could fail suddenly.
The tire pressure label on your Audi lists the recommended cold tire
inflation pressures at maximum capacity for the new, original equip ­
ment tires that were on your vehicle at the time it was manufac­
tured. For the location of the label
~ page 330, fig. 274.
Most tires lose air naturally over time. They can also lose some air if
you drive over a pothole or hit a curb while parking. It is usually not possible to see whether the radial tires used today are underinflated
just by looking at them.
Therefore, be sure to check tire pressures at least once a month and
always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you would not consider to be
"long ." See~
page 335, "Tires and vehicle load limits" for more
important information.
Always use an accurate tire pressure gauge when checking and
adjusting inflation pressures . Check all of the tires and be sure not
to forget the spare tire . If the pressure in any tire is too high when
the tire is "cold," let air out of the tire slowly with the edge of the tire
gauge and keep checking the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the difference between the
pressure in the cold tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you
plan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember that the vehicle manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle. .,,_

It is important to ch eck the ti re pressure when the tires are cold .
• Read the req uire d tire p re s su re from the tire press ure la b el. On
USA vehicles, the tire p ressure label is located on the driver's side
8 -p illar. On Canada vehic les, the tire p ressure label is located either
on the driv er's sid e 8-pill ar or ins ide t he fuel fill er flap.
• Tur n the va lve stem cap c ounte r-cl ockwise to rem ove it fr om t he

& WARNING
Incorrect tire pressures and /or underinflation can lead sudden tire
failure, loss of control, collision , serious personal injury or even
death .
• When the warning symbol appears in the instrument
cluster, stop and inspect the tires .
& WARNING (continued)
• Incorrect tire pressure and /or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure , including a blowout and sudden deflation,
causing loss of vehicle control .
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on
a sticker on the driver's side B-pillar or on the inside of the fuel
filler flap.
• Only when all tires on the vehicle are filled to the correct pres­
sure , the tire pressure monitoring system* can work corre ctly.
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is essential that the driver observe
the specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pressure mon itoring system* .
• Always inflate tires to the recommended and correct tire pres ­
s ure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation , sudden tire failure and loss
of control.
• Excessive speed and /overloading can cause heat build-up ,
s udden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service station
to check the tire pressure and add air as required. _..

0 Note
Driving without valve stem caps can cause damage to the tire
valves. To prevent this, always make sure that factory installed valve
stem caps on all wheels are securely mounted on the valve .
W For the sake of the environment
Underinflated tires will also increase the fuel consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle and
any tire can carry . A vehicle that is overloaded will not handle well
and is more difficult to stop. Overloading can not only lead to loss
of vehicle control, but can also damage important parts of the
vehicle and can lead to sudden tire failure, including a blowout and
sudden deflation that can cause the vehicle to crash.
Your safety and that of your passengers also depends on making
sure that load limits are not exceeded. Vehicle load includes every­
body and everything in and on the vehicle. These load limits are
technically referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR"l.
The "GVWR" includes the weight of the basic vehicle, all factory
installed accessories, a full tank of fuel, oil , coolant and other fluids
plus maximum load. The maximum load includes the number of
passengers that the vehicle is intended to carry ("seating capacity")
with an assumed weight of 150 lbs (68 kg) for each passenger at a
designated seating position and the total weight of any luggage in
the vehicle. If you tow a trailer, the weight of the trailer hitch and the
tongue weight of the loaded trailer must be included as part of the
vehicle load.
The
Gross Axle Weight Rating ("GAWR"l is the maximum load that
can be applied at each of the vehicle's two axles. The
Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compliance sticker label located either on
the driver's side 8-pillar or on the inside of the fuel filler flap. Your
Audi has 5 seating positions, 2 in the front and 3 in the rear for total
seating capacity of 5. Vehicles with power individual rear seats*
have 4 seating positions, 2 in the front and 2 in the rear for total
seating capacity of 4. Each seating position has a safety belt
~ page 211, "Safety belts".
The fact that there is an upper limit to your vehicle's Gross Vehicle
Weight Rating means that the total weight of whatever is being
carried in the vehicle (including the weight of a trailer hitch and the
tongue weight of the loaded trailer) is limited. The more passengers
in the vehicle or passengers who are heavier than the standard
weights assumed mean that less weight can be carried as luggage.
The tire pressure label on your Audi also lists the maximum
combined weight of all of the occupants and luggage or other cargo
that the vehicle can carry. For the location of the label
~ page 330,
fig. 274.
& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death.
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly,
including a blowout and sudden deflation, causing loss of control
and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating. •

The tires and rims are essential parts of the vehicle 's design. The
tires and rims approved by Audi are specially matched to the char­
acteristics of the vehicle and can make a major contribution to good
road hold ing and safe handling when in good cond ition and prop­
erly inflated =>& .
We recommend that a ll work on tires and wheels be performed by
an authorized Audi dealer. They are familiar with recommended
procedures and have the necessary special tools and spare parts as
well as the proper facilities for d isposing of the old tires.
Authorized Audi dea lers have the necessary info rmation about tech ­
nical requirements for insta lling or changing tires and rims.
R epl ac ing tires and wheels
Tires shou ld be replaced at least in pairs and not individually (for
examp le both front tires or both rear tires together).
Be sure to read and heed the information to the tire pressure moni ­
toring system*=>
page 340.
Always buy replacement radial tires that have the same specifica ­
tions as the tires approved for your vehicle by Audi. Rep lacement
tires must always have the same load rating specification as the
origina l equipment or approved optional t ires listed in the table
=>
page 330.
