@ Tips
If the climate control system is operating
in cooling mode, a ir flows primarily 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 conditioner, engine pow­
er is reduced and fuel consumption increases.
To save fuel, you should use the air condition ­
e r only when necessary. Also please note the
following points :
.,. To save fuel, turn off cooling mode by press­
ing the
I AC ! button (indicator light goes
out) .
.,. In add ition, if you open the window or the
Panoramic sliding sunroof* while driving,
turn off cooling mode by p ress ing the
IACI
button (indicator light goes out).
.,. If the vehicle is extremely hot due to the
heat of the sun, briefly open doors and win­
dows.
@ For the sake of the environment
By reducing the amount of fue l you use,
you also reduce the amount of poll utants
emitted into the air. W

Traile r to wing we ight s
W it h a fac tor y-ins talled trailer hitch, the
maximum permissible trailer we ight is 6 ,615
lbs (3,000 kg) . The maximum permissible un­
braked trailer weight is 1,650 lbs (750 kg) .
W ith an aft er mar ket trailer hitch, the maxi­
m um permissible trailer we ight is 5,512 lbs
(2,500 kg) . These specifica tions apply when
driving on roads having an incline of less than
12%.
Perm issible tongue load
F or best vehicle handli ng u nder these
changed condit ions, adjust the trailer load so
that the tongue load is at the maxim um al ­
l owable or slightly lower. Yo u can get an ap­
proximation of the tongu e load with a bath­
room scale o r you c an measu re the load at a
trucking company or weighing s ta tion.
With a factory-in stalled trailer hitch, the
maximum permissib le load on the ball hitch
may not exceed 662 lbs (300 kg). With an af­
termarket trailer hi tch, the maximum permis­
sib le load on the ball h itch 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 t ra iler is held secure ly
in place to prevent it from shift ing forward,
backward or sideways.

Ball m ount
The trailer hi tch may only be used w ith suita­
ble ball mount and ball¢
fig. 219 . Installa ­
tion of the h itch ball must be carried out in ac­
cordance with the manufacturer's inst ruc­
tions . At the height dimens ion of 1.5 in
(38 .5 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 impo rtant that the cooling system's
performance is up to the additional load.
Make sure that the cooling system has enough
fluid.
T ire pressur e
When towing a trailer, inflate the tires of your
vehicle to the cold ti re pressu re listed under
" F u ll load" on the tire pressure label. The tire
pressure label is located on the drive r's side B­
pillar . Inflate trailer tires to t railer and tire
manufacturers' specifications.
Lights
T he headlight settings should be checked wi th
t h e trai ler attached before d riving
off. Check
to make s ure both vehicle and trailer lights
are worki ng properly.
Safety chains
Be sure trailer safety chains are properly con­
nected from the trai le r to the hitch on the ve­
hicle. Leave enough slack in the ch ains to pe r­
mit turning corners. When you install safety
chains, make sure they will not drag on the
road when you are driving. ..,.

C hanging the engine oil
The engine oil and o il fil te r must be changed
according to the m ileage (ki lomete rs) and
time inte rva ls spe cified in your vehicle 's War­
ra nty
& Main ten ance booklet. Do not ex ceed
these in tervals - harmful depos its from ol d
engine o il can reduce engine performance an d
can lead to expensive engi ne re pairs.
C hanging the o il at th e recommen ded i nte r­
v al s is so very impor tant because t he lub ric at ­
ing p roperties o f oi l decrease gra dually du ring
norma l vehicle use . If you are not sure when
you have yo ur oil changed, ask yo ur aut ho r­
i z ed A udi Service Advisor.
Unde r some ci rc u ms tances the engine o il
should even be change d mo re frequently .
C hange o il more often if you drive mostly
short d istances, ope rate the vehicle in d usty
areas or mostly under stop-and-go traffic con­
d it ions, or when you use your veh icle w he re
tem peratures stay below freez ing poin t fo r
l ong periods .
Detergent addit ives i n the o il w ill make fresh
oil look dark after the eng ine has been run­
ni ng fo r a shor t time . This is no rma l and is not
a reason to change the o il mo re often tha n

Damage or malfunctions due to lack of
maintenance
It is essential that yo u change your oil at the
recommended interva ls using only engine o il

from eng ine to engi ne and may cha nge over
t h e life of the engine. Engines tend to use
more o il du ring t he b reak-in pe riod tha n they

driven and the operati ng conditions, oil con ­
s u mption can be up to 1 q uart per 1, 200
miles (1 liter per 2,000 km) . Consumption
may be higher within the first 3,000 m iles
(5,000 km) .
Un der normal con ditions , the rate o f oi l con­

We urge you to check the engine oil level at
regular intervals, preferably every time you
fill the fuel tank, and always before a long
trip.
The oil pressure 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 driving (above 1500 rpm), a
buzzer will sound. It indicates that the oil
pressure is too low . Stop the engine immedi·
ately, check the engine oil level and add oil if
necessary. If the engine oil level is normal,
but the light continues to flash, do not keep
driving or let the engine idle, as damage may
occur .

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 cooli ng system has bee n filled a t the fac­
t ory with a permanent coolant which does not
need to be c hanged . The coo lant cons ists of a
mixture of water and the manufacturer's gly ­
col-based coo lant additive G l3 antifreeze
with anticorrosion additives (50% for USA
models; 60% for Canadian mode ls). This m ix­
ture both assures the necessary frost protec­
tion and protects meta l compone nts in t he
engine's cool ing system from corros io n and
sca ling.
It also raises the boiling point of the
c oolant.
Do not reduce the concentration of the cool ­
ant in the s ummer by adding p lai n water .
The
proportion of coolant additive must be at
lea st 50 % but not more than 60 %
to main ­
tai n antifree ze pro te ct io n a nd coo ling eff icien­
cy .
If the coo lant fros t protection is too low,
the coo lant co uld freeze and damage the vehi-
cle heating and engine cooling system. .,..

266 Check ing and filling
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.
_& WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARN INGS
¢ .&. in Working in the engine
compartment on page 258.
(D Note
- Befo re winter se ts in, have the coolant
checked to see if t he coolant addit ive 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 co ld. If necessary, in­
crease the proport ion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­ ditive G12++ or G13 for your vehicle.
Th is coo lant add itive 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 coo lant and se­
r ious engine damage.
- Do not add any type of radiator leak sea l­
ant to your vehicle's engine coolant.
Adding rad iator repair fluid may adve rse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle Limited Wa rranty.
