OP-eration
The supply of a ir to the outlets is controlled either automat ically or
manually depend ing on the operation mode selected. The airflow
from all outlets can be heated, unheated or cooled .
The heater outlets for the rear footwells are located under the front
seats. When you select outlets@, air is also directed to the rear foot­
wells.
[I) Tips
• When defrosting/defogging the windows, air flows from outlets
(D ,@ and @. To defrost or defog the windows as rapidly as poss ible,
air outlets ® should be opened
fully with the adjuster wheels.
• When the air conditioner is working, cooled air w ill flow primarily
from outlets @,® and @. To assure adequate cooling, outlets ®
and © should never be completely closed.•
Using the climate controls economically
Using the climate controls prudently can help save fuel .
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should use
the air conditioner only when necessary. Also please note the
following points:
- If you want to save fuel, switch off the air conditioner .
- If you are going to drive with the windows open, switch off
the air conditioner.
By reducing the amount of fuel you use, you also reduce the amount
of polluta nts emitted into the air. •

Trailer towing
"---------------------------------------------------
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor ­
tation .
If you p lan to tow a t railer, p lease remember that the additional load
w ill affect durability, economy and performance.
Tr ailer towing not on ly p laces mo re s tress on the vehicle, it also calls
for more concentration from the driver.
For this reasons, a lways fo llow the operating and driv ing instr uctions
prov ided and use common sense .•
Technical requirements
Trailer hitch
Use a we ight-carrying hitch conforming to the gross trai ler weight .
Th e h itch mus t be suit able for your veh icle and t railer and mus t be
mounted securely on the vehicle's chassis at a
technically sound l oca­
t ion. Use on ly a tra ile r hi tch w ith removable b all moun t. Alw ays check
w ith the trailer hitch manufacturer to make sure that you are using
t he correc t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way t hat it does not interfere
w ith the impact -ab sorb ing bumper system. No mod ifi cations s houl d
be made to the vehicle exhaust and brake systems . From t ime to
t ime, che ck t hat all hitch mou nting bolts rema in securely faste ned.
W hen you are no t tow ing a trai ler, remove the trailer hitch ball
mount. This prevents the hitch from ca using damage should your
veh icle be s truck from behind=>&.
Tire pressure
When towing a tra iler, inflate the tires of you r vehicle to the cold tire
pressu re listed under "Full lo ad"on t he st ick er o n the r ight doo rjamb.
I n flate trailer t ires to trai ler and tire manufacturers' specifications .
Lights
The headlight settings should be checked with the tra iler attached
befo re d riving o ff. Have the headlights adjusted as necess ary s o that
you can see the road ahead but not b lind oncoming t raffic.
Check to make s ure bo th vehicle and t railer lights a re wor king prop­
er ly.
Engine cooling system
Towing a trailer ma kes t he engin e work harder. It is important t hat
t he cooling sys tem' s per formance stands up to the add ition al stra in.
M ake sure that the coo ling sys tem has eno ugh fluid .
Trailer brakes
If your trai ler is equipped with a braking system, check to be su re that
it confo rms to all regula tions .
Th e tra ile r hydrau lic brake system must not be directly con nected to
the vehicle's hydraulic b rake system.
Safety chains
Be sure trailer safety cha ins are p roper ly connected from the t rai ler
to the hitch on the vehicle. Leave enough s lac k in t he chai ns to permit
t u rni ng corners. When you insta ll safety chains, ma ke s ure t hey will
not d rag on t he road when yo u are d riving .
The chai ns should cross under the trailer tongue to prevent it from
drop ping in ca se of separat io n from t he hitch.
Trailer lights
Trailer lights must meet all regulat ions. Be su re to chec k w ith your
author ized A udi dealer for correct wiring, switches and relays. _.

___ C_ h_ e_c _k _i _ n _g ~ a_n _d_ f_il _l_in _ g _________________________________________ _
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and-go traff ic conditions, or when you use your vehicle where temper­
atures stay below freezing point for long periods .
Detergent additives in the oil will make fresh oil look dark after the
engine has been run ning for a short time . This is normal and is not a
reason to change the oil more often than recommended .
Damage or malfunctions due to lack of maintenance
It is essentia l that you change your oi l at the recommended intervals
using only engine oil that complies with Audi oi l standard VW 502 00
(vehicles with gasoline engine) or VW 507 00 (vehicles with diesel
engine). Your Limited New Vehicle Warranty does not cover damage
or malfunctions due to failure to follow recommended maintenance
and use requirements as set forth in the Audi Owner's Manua l and
Warranty
& Maintenance booklet. Your dealer will have to deny
warranty coverage unless you present to the dealer proof in the form
of Service or Repair Orders that all scheduled maintenance was
performed in a timely manner .•
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 cooling of internal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumpt ion varies from engine to engine
and may change significant ly over the life of the eng ine. Typically,
engines with a specified break- in period (see~
page 197) consume
more oi l during the break-in period than they cons ume after oil
consumption has stabilized.
Under normal cond itions, the rate of oil consumpt ion depends on the
quality and vis cosity of the oil, the RPM (revol utions pe r minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oi l dilution from water condensation or fuel residue and the ox
idation level of the o il. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level , see
Note .
If the yellow engine oil level warning symbol in the instrument
cl uster .... lights up, you should check the oil level as soon as possible
with the oil dipstick~ page 231. Top off the o il at your earliest
convenience ~
page 232.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Work ing in the engine
compartment" on
page 226.
0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine .
[ i ] Tips
• The oil pressure warning display 't::r. is not an indicator of the oil
level. Do not rely on it. Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and alway s
before going on a long trip.
• If you have the impression your eng ine consumes excessive
amounts of oi l, we recommend that you consu lt your authorized Audi
dea ler to have the cause of your concern properly diagnosed. Keep in
mind that the accurate measurement of oil consumption requires
great care and may take some time . Your authorized Audi dea le r has
instructions about how to measure oil consumption accurately. •
