Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driving
the vehicle.
11-Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at rail­
road cross ings, or at traffic lights that have
long waits on red. Turning the engine
off for
just 30-40 seconds saves more fuel than is
burned starting the engine again.
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting. If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel .
11-Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects fuel
consumption.
Check your oil each time you fill your tank.
Driving and environment 233
The amount of oil used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(S,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
t enance booklet. Lack of prop er mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission cont ro l system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
11-Try to avoid driving short distances w ith a
cold engine.
T he engine and cata lytic converter have to
reach their optimal operating temperature to
reduce fuel consumpt ion and noxious emis­
s ions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/l00km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 miles (4 km), liJI,

Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system.
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
Applies to vehicles : wit h gasoli ne e ng in e
A majo r concern among many auto manufac­
ture rs is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline g rades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
Fuel supply and filling your fuel tank 249
brands include additives to keep engine and
fuel systems clean, they are not equally effec­
tive .
Audi recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
webs ite (www.toptiergas.com).
After an extended per iod of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
CD Note
Damage or malf unct ion due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diesel engine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2. The ULSD No. 2 meets the ASTM D97S.
Diesel fuel with concentrations of biodiesel
highe r than S % such as Bll, B2O or BlOO are
strictly prohib ited .
Se rv ice stat ion fuel pumps are labeled with
the cor rect fuel informat ion for easy recogn i­
tion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries .
ULSD No. 2 can become thicker in very cold
temperatu res, and this can impair the en­
gine's start ing and running. Depending on the
season, gas stations provide ULSD No. 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usua l.
CD Note
-Yo ur vehicle's diesel engine was de­
signed soley for use with ULSD No. 2.
Therefore, never use gasoline, heating oil, other fuels or flow improvers. These
conta in substances that will severely
damage the fuel system and the engine . .,.

8_ WARNING
Stop! Before working in the engine com­
partment, always read and heed all WARN ­
INGS
~ .&. in Working in the engine com­
partment on page
256 . The engine com­
partment of any motor veh icle is a poten­
tially dangerous area and can cause ser i­
ous personal injury.
8_ WARNING ,,,__
If you must change the engine oil in your
vehicle:
- Always wea r eye protection .
- T o reduce the ris k of burns from hot en-
gine oil let the engine cool down to the
touch.
- Whe n removing the oil drain plug with
yo ur fingers, stay as far away as poss ible.
Always keep your forearm paralle l to the
ground to he lp prevent hot oil from run­
ning down your arm.
- Drain the oi l into a container designed
for this pu rpose, one large enough to
hold at least the total amount of oil in
your engine.
- To reduce the risk of poisoning, never use
empty food or beverage containers that
might m islead someone into dr ink ing
from them.
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Cont inuous contact with used engine oil
is harmful to your skin. Always protect
your sk in by washing thoroughly with
soap and water .
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adverse ly affect your Audi Limit­
ed New Vehicle Warranty.
@i For the sake of the environment
- Before changing the oil, first make sure
you know where you can properly dispose of the old oil.
-
.
- Always dispose of used oil p roperly. Nev ­
er dump it on garden soil, in wooded
areas, into st reams or down sewage
dra ins.
- Recycle used oi l by taking it to a used en­
gine oil collection facility in your area, or
contact a service station.
- We strongly recommend that yo u have
your oil changed by an authorized Audi
dealer or a qualified workshop with the
special tools and expert ise required, and
proper means of disposal.
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­
tects the engine from freezing in the winter.
T he cooling sys tem is sealed and genera lly re­
quires little attention.
The cooling system has been fi lled at the fac­
tory with a permanent coolant which does not need to be changed. The coo lant cons ists of a
mixtu re of specially conditioned water and the
manufacturer's g lycol -basedcoo la nt add
i-
tive G l3 antifreeze with anticorrosion addi ­
tives (SO% for USA mode ls; 60% for Canadian
models). This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the eng ine's cooling system from
corros ion and scaling.
It also ra ises the bo il­
i ng po int of the coolant .
Do not reduce the concentration of the cool­
ant in the summer by adding p lain wate r. Th e
proportion of coo lant additiv e mu st be at
l e as t 50 °/4 but not m ore than 60°/4
to main­
ta in ant ifreeze protect io n and cooling eff ic ien­
c y.
If the coo lant fros t protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system.
For year- round driving, antifreeze is added at
t h e factory fo r temperatures down to:
- -31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.

264 Check ing and filling
Coolant lo ss
Coolant loss may indicate a l ea k in t he cooling
system. In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
se ale d system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefully in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap .
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system
or hot eng ine parts. Under certain condi­
t io ns, the ethy lene g lycol in engine cool­
an t ca n ca tch f ire.
0 Note
Do not add any type of radiator leak seal­
ant to your vehicle's eng ine coolant. Add­
ing radiato r repair fluid may adve rsely af­
fect the function and performance of your
cooling system and could res ult in damage
not covered by your New Vehicle Limited
Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anything i n the engine com­
pa rtmen t,
a lwa ys read and heed all WARN ­
INGS c:::> A in Working in the engine compart ­
ment on page 256.
.. Tu rn off the engine .
.. Let the engine cool down.
.. Place a thick rag over the coo lant expansion
tank
c> page 263 , fig. 246 and carefully
twist the cap counter-clockwise c> ,&. .
.. Add coo lant m ixed in the correct rat io
c:::> page 262, Coolant.
.. Twist the cap o n again tightly.
Rep lacement engine coo lant must conform to
exact spec ificat ions
c> page 262, Coolant.
We recommend using only coo lant add it ive
G12 ++, G13 or in an emergency G12 +. Do
not
use a different add itive. In an emergency use
plain water until you can get the correct addi­
t ive and can restore the correct ratio . This
shou ld be done as soon as poss ib le.
If you have lost a considerab le amount of
coolant, the n you should add cold ant ifreeze
and co ld water on ly when the eng ine is cold .
Always use
new engine coolant when refilling.
Do not fi ll coo lant above the "MAX" mark. Ex­
cess coolant will be forced o ut through the
pressure relief valve in the cap when the en­
gine becomes hot.
A 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 coo l
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, th ick rag.
- Turn the cap s low ly and very carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engi ne parts. Under certain
cond it ions, the ethylene g lycol in e n­
gine coolant can catch fire .
