Instruments and indicator lights
reached the reserve mark, the bottom LED will
turn red and the
ljJ indicator light turns on
¢
page 23. The bottom LED blinks red when
the fuel level is very low.
The on-board computer shows the range based
on the fuel level¢
page 28, On-board comput­
er display.
For the tank capacity in your vehicle, refer to the
Technical Data
¢ page 260.
(D Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter.
Coolant temperature indicator
In vehicles without a coolant temperature indica­
tor, an indicator light. will turn on when the
coolant temperature is too high ¢
page 19. Re­
fer to ¢(1) .
The coolant temperature indicator @c:>
page 10,
fig . 3 only works when the ignition is switched
on . To prevent engine damage, please observe
the following notes about the temperature rang­
es.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­ perature yet. Avoid high engine speeds, full accel­
erating and heavy engine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions . The
LEDs higher up may turn on if the engine is under
heavy load or the outside temperature is high.
This is no cause for concern as long as the. in­
dicator light in the instrument cluster does not
turn on.
12
Hot range
If the LEDs in the upper area of the display and
the . indicator light in the instrument cluster
display turn on, the coolant temperature is too
high
c:> page 19 .
A WARNING
-Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. Wait until you no longer see or hear
steam or coolant escaping.
- The engine compartment in any vehicle can
be a dangerous area . Stop the engine and al­
low it to cool before working in the engine
compartment. Always follow the informa­
tion found in ¢
page 198, Working in the
engine compartment.
(D Note
- In vehicles with a boost pressure indicator* ,
this indicator replaces the temperature dis­
play. To promote a long engine service life,
avoiding high engine speeds, full accelera­
tion and heavy engine loads during approxi­
mately the first 15 minutes when the en­
gine is cold is recommended . The amount of
time until the engine is warm depends on
the outside temperature . Check the engine
oil temperature* if necessary .
c:> page 30
-Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy engine
load.
- The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance.

Checking and F ill in g
Using the proper engine o il is important for the
functionality and service life of the engine. Your
engine was factory-fi lled w ith a high-quality o il
which can usually be used throughout the ent ire
year.
@) Note
Your L imited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended ma intenance and use
requ irements as set forth in the Audi Ow ne r's
Manual and Wa rranty
& Ma intenance booklet .
- Use only a high quality eng ine oil t hat ex-
pressly comp lies w ith the Audi o il quality
standard specified for your vehicle's e ngine .
Using a ny other oil can cause se rious engine
damage.
- Do not mix any lubricants o r othe r addit ives
i nto the engine oil. Doing so can cause en ­
g ine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
y o ur eng ine requires, you m ay add a total of
no more than 0.5 quart/li ter o f a h igh-quali ty
"synthet ic"oil that meets the fo llowing speci ­
fications .
- V ehicles wi th gasoline engine: AC EA A3 o r
API SM with a viscosity grade of SAE 0W- 30,
SAE SW -30 or SAE SW-40 .
- Vehicles with d iesel engine: ACEA C3 o r
API CF with a viscosity g rade of SAE 0W-30
or SAE SW-30.

www.aud iusa.com or www .aud icanada .ca.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubrication and cool­ ing of in ternal engine components, all internal
202
combust ion engines consume a certa in amoun t
of oil. Oil consumptio n varies from engine to en­
gine and may change sign ificant ly over the li fe of
the engine . Typically, eng ines with a specif ied
break-in period (see
¢ page 70) consume more
o il dur ing the break-in per iod than they consume
after oil consumption has s tabilized .
Under normal cond itions, the rate of oil con­
sump tion depends on the quality and viscos ity of
the oil, the RPM (revolutions per minute) at
wh ich the engine is operated, the ambie nt tem­
perature and road cond it ions . Furthe r facto rs a re
t h e amo unt of o il di lution from water conde nsa­
t ion or fue l residue and the ox idat ion leve l o f the
o il. As any engine is s ubject to wear as mileage
builds up, the oil consumption may increase ove r
time unt il rep lacement of wo rn components may
become necessary.
With a ll these va riab les coming into p lay, no
standard rate of oil consumption can be estab ­
li shed or spec ified. There is no alte rnative to reg­
ul ar and frequent checking o f the oil leve l, see
Note .
If the yellow engine oi l level warning sym bo l Ill
in the instrument cluster lights up, yo u should
check the o il level as soon as possible
¢ page 203. Top off the oil at your earliest con­
venience
¢ page 203.
A WARNING
Before you c heck anythi ng in the eng ine com ­
partment, always read and heed al l WAR N­
IN GS ¢page 198.
(D Note
Driving w it h an insufficient o il level is likely to
cause severe damage to the engine.
(D Tips
- The oil pressure warning d isplay. is not
an indicator of the oil level. Do not rely on
it. Instead, check th e oil level in your en­
gine at regular intervals, preferably each
time you refuel , and alway s before going
on a long trip.

-Overloading can lead to loss of
vehicle control and increase the risk of an accident. Read
and follow the important
safety precautions in
¢ page 22 7, Tires and vehicle
load limits.
-The tire must flex more if the
tire pressure is too low or if the vehicle speed or load are
too high. This heats the tire up
too much. This increases the risk of an accident because it
can cause the tire to burst and result in loss of vehicle con­
trol.
-Incorrect tire pressure increas­
es tire wear and has a negative

@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(1) Tips
Audi recommends using the
tire pressure specified for a nor­mal load
¢ table on page 226
or for a full load when the vehi­
cle is partially loaded.
Make sure that the tire designa ­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table .
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed.

.&_ WARNING
Please note the important safe­
ty precautions regarding tire pressure ¢
page 224 and load
limits¢
page 227.
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 al­
so 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 pas ­
sengers also depends on making
sure that load limits are not ex­ ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gro ss Vehicle We ight Rating
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
Tires and wheels
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in ­
tended to carry ("seating capac i­
ty") with an assumed weight of
150 lbs . (68 kg) for each passen­
ger at a designated seating posi­
tion 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 includ­ ed as part of the vehicle load.
The
Gross Ax le Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two ax les.
T he fact that there is an upper
limit to your vehicle's Gross Vehi ­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehic le (inc luding
the weight of a trai ler hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard we ights assumed mean
that less weight can be carried as luggage.
