@ Tips
If the climate co ntrol syste m is operati ng
in cooling mode, a ir flows primari ly from
the outlets in the center conso le and in the
door pillars. To achieve adequate cooling,
you should never close the outlets com­
pletely .
Using climate control economically
Using the climate controls prudently can help
save fuel.
When you use the air cond it ioner , engine pow­
er is reduced and fuel consumption increases.
To save fuel, you should use the air condition ­
e r on ly w hen necessary . Also please note the
following points :
.,. To save fuel, tu rn off coo ling mode by press­
ing the
I A/Cl button (indicator lig ht goes
out) .
.,. In add it ion, if you open the w indow o r the
Pano ram ic s liding sunroof* wh ile driving,
t ur n off cooli ng mode by p ress ing the
IA/C l
button (ind icator light goes ou t).
.,. If the vehicle is extremely hot due to the
heat of the s un, briefly open doors and win­
dows.
@ For the sake of the environment
By reducing the amount of fue l yo u use,
you also reduce the amount of poll utants
emitted into the air.

Fig. 231 Perm itted ba ll posit ion of the trailer hitch
Trailer towing weights
With a factory-installed trailer hitch, the
maximum permissible trailer weight is 6,615
lbs (3,000 kg). The maximum permissible un­
braked trailer weight is 1,650 lbs (750 kg).
With an
aftermarket trailer hitch, the maxi­
mum permissible trailer weight is 5,512 lbs
(2,500 kg). These specifications apply when
driving on roads having an incline of less than
12%.
Permissible tongue load
For best vehicle handling under these
changed cond itions, adjust the trailer load so
that the tongue load is at the maximum al­
lowable or slightly lower. You can get an ap­
proximation of the tongue load with a bath­
room scale or you can measure the load at a
trucking company or weighing station .
With a
factory-installed trailer hitch, the
maximum permissible load on the ball hitch Trailer towing 241
may not exceed 662 lbs (300 kg). With an
af­
termarket
trailer hitch, the maximum permis­
sible load on the ball hitch may not exceed
551 lbs (250 kg).
It is recommended to use
the maximum permissible load.
Trailer load distribution
Be sure the load in the trailer is held securely
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢ .& in Driving instructions on page 242.
Ball mount
The trailer hitch may only be used with suita­
ble ball mount and ball ¢
fig. 231. Installa­
tion of the hitch ball must be carried out in ac­
cordance with the manufacturer's instruc­
tions. At the height dimension of 1.5 in
(38.S mm) a tolerance of+/- 0.5 in (12. 7 mm)
is permissible.
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is important that the cooling system's
performance is up to the additional load.
Make sure that the cooling system has enough
fluid .
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressure listed under
"Full load" on the tire pressure label. The tire
pressure label is located on the driver's side B­
pillar . Inflate trailer tires to trailer and tire
manufacturers' specifications .
Lights
The headlight settings should be checked with
the trailer attached before driving
off. Check
to make sure both vehicle and trailer lights
are working properly .
Safety chains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the
ve­
hicle. Leave enough slack in the chains to per­
mit turning corners. When you install safety

C han gin g the en gin e o il
The engine oil and oil filter must be changed
according to the m ileage (ki lomete rs) and
time inte rva ls specified in your vehicle 's War­
r anty
& M aintenance booklet. Do not ex ceed
t hese intervals -harmf ul depos its from old
engine oi l can reduce engine performance and
can lead to expensive engine repairs.
Changing the o il at the recommended inte r­
va ls is so very important because the lub ric at­
ing p roperties o f oi l decrease grad ually during
norma l vehicle use . If you are not sure when
you have yo ur oi l changed, ask your a uthor­
ized A udi Service Advisor.
Unde r some ci rc u mstances the engine o il
should even be changed more frequently.
Change o il more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
d itions, or when you use your vehicle where
temperatures stay below freezing po int for
l ong periods .
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
ni ng fo r a short time . This is no rmal and is not
a reason to change the o il mo re often than
r ec om mended.
Damage or malfun ctions due to lack of
maintenance
It is essential that yo u change your oil at the
recommended interva ls using only engine oil
that complies with Audi oi l standard

· Engine oil consumption
To provide effective l ubr ication and cooling for
interna l eng ine parts, all interna l combustion
engines use some oi l. Oi l consumption varies
from eng ine to engine and may change over
the life of the engine . Engines tend to use
more o il du ring the b reak-in period tha n they
do afterward, when o il cons umption has sta­
bilized. Depend ing on the way the vehicle is
driven and the operating conditions, oil con­
s u mption can be up to
1 quart per 1,200
miles (l liter per 2,000 km) . Consumption
may be higher within the first
3,000 m iles
(5,000 km) .
U nder normal conditions , the rate of oi l con ­
s u mption depends on oi l quality as well as vis­
cosity, engine speed (rpm), outs ide tempera ­
ture, road conditions, the amount of oil dilu­
tion caused by condensed water or fue l resi­
due, and ox idat ion of the o il. Oi l consumption
may increas e with eng ine wear over time, un­
t il rep lacement of worn engine pa rts may be­
come ne cessa ry.
Because of all these var iables, there is no
standard o r "n orma l" rate of o il cons umption .
We urge you to check the engine oil level at
regular interval s, preferably every time y ou
fill the fuel t ank, and always before a long
trip .
The oil pres sure warning light. i s not an
indicator of low engine oil level. If the warn ­
ing light does not go out after starting, or
flashes while dr iving (above 1500 rpm), a
buzzer will sound. It indicate s that the oil
pressure is too low . Stop the engine immedi ­
ately , check the engine oil level and add oil if
necessa ry. If the engine oil level is normal,
but the l ight continues to fla sh, do not keep
driving or let the engine idle, as damage may
occur .

A WARNING
Stop! Before working in the engine com­
partment, a lways read and heed all WARN­
INGS
c> .&. in Working in the engine com­
partment on page 257. The engine com­
partment of any motor veh icle is a poten­
tially dangerous a rea and can cause ser i­
ous personal injury.
A WARNING
If you must change the engine oil in your
vehicle:
- Always wea r eye p rotection.
- T o reduce the r isk of burns from hot en-
gine oil let the engine cool down to the
touch.
- When removing the oil drai n plug with
yo ur finge rs, stay as far away as possible.
Always keep your forea rm pa ra ll el t o the
ground to he lp prevent hot oil from run­
ning down your arm.
- Dr ain the o il into a container designed
for this p urpose, one large enough to
hold at least the total amount of oil in
yo ur engine .
- T o reduce the r is k of po ison ing, never use
empty food or beverage containers that
might mis lead someone into drinking
from them.
- Engine oil is poisono us. Keep it well out
of the reach of children.
- Cont inuo us contact with used engine oil
is harmful to your skin . Always protect
yo ur sk in by washing thoro ughly with
soap and water.
@ Note
Never mix oil ad ditives with your engine
oil. These additives can damage your en­
gine and adverse ly affect your Audi Limit­
ed New Vehicle Warranty.
(® For the sake of the environment
- Before changing the oil, first make sure
you know where you can prope rly dispose
of the old o il.
- Always dispose of used oil p roperly. Nev­
er dump it on garden soil, in wooded
areas, into streams or down sewage
dra ins.
- Recycle used o il by tak ing it to a used en­
gine oil collection facility in your area, or
contact a se rvice station.
- We strongly recommend that yo u have
your oil cha nged by an authorized Audi
dealer or a qualified workshop with the
special tools a nd expert ise required, and
prope r m eans 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.
T he coo lin g sys tem has been fi lled a t the fac­
tory with a permanent coolan t which does not
need to be changed . The coo lant cons ists of a
mixture of specially conditioned water and the
manufacture r's g lycol-basedcoo lant add i-
t ive
Gl3 antifreeze with anticorrosion addi­
t ives (SO% for USA models; 60% for Canadian
models). This mixture both assures the neces­
sa ry frost protection and protects metal com ­
ponents in the eng ine's cooling system from
corros io n and scaling.
It also ra ises the bo il­
i ng po in t of the coolan t.
Do not reduce the concentration of the cool ­
ant in the summer by addi ng p lain water .
The
proportion of coolant additiv e must be at
lea st 50 % but not more than 60°/o
to main ­
t ai n ant ifree ze pro te ct io n and cooling eff ic ien­
cy .
If the coo lant fros t protec tion is too low '
t h e coo lant co uld freeze and damage the vehi-
cle heating and engine cooling system. ..,.

For year-round driv ing, antifreeze is added at
the factory for temperatures down to:
- - 31 °F (- 35 °C) USA
- - 40 °F ( - 40 °C) Canada .
If you mus t add coolant, use a mixture of wa­
ter and coolant additive. Mixing the coolant
additive with distilled water is recommended .
A WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
A in Working in the engine
compartment on page 257.
(D Note
-Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extremely cold.
If necessary, in­
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive Gl2++ or G13 for your vehicle.
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection . The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in damage not covered by your New Vehicle
Limited Warranty.

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 32 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­ ommend you check the coolant level from
time to time .

26 6 Ch eck 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 ions, the ethy lene g lycol in engine cool­
an t can 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 .

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 considerable amount of
coolant, then you should add cold ant ifreeze
and co ld water only when the eng ine is cold .
Always use
new engine coolant when refilling.
Do not fi ll coolant above the "MAX" mark. Ex­
cess coolant will be forc ed out through the
pressure relief valve in the cap when the en­
gine becomes hot.
