A WARNING
-Always observe the warning in¢ page 191,
before open ing the hood and check ing the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
cou ld burn yourself. Let the eng ine cool off
first so that you cannot hear o r see any
steam o r engine coo lant.
0 Note
- Mount ing additional lights or accesso ries in
fron t of the a ir inlets reduces the cooling ef­
fect of the radia to r. A t high outside temper­
atu res or high e ngine load, the eng ine could
overheat.
- The front spo iler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving. If the spo iler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­ ized Audi dealer for assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revo­
lutions per minutes).
If engine RPM drops be low 1,5 00, you should
downshift to the next lower gea r. T he red area at
the end of the scale indicates max imum permis­
sible eng ine RPM after the break-in period . Be­
fore reachi ng this area, move the selector lever to
position D/S or ease your foot off the accelerator
pedal.
(D Note
The tachometer needle@¢ page 10, fig. 3
should o nly briefly be in the red zone: you
co uld damage your eng ine! The beginn ing of
the r ed zone varies depending on the engine.
@ For the sake of the environment
Upshift ing early saves fuel and reduces eng ine
noise .

Warm and cold
Warm and cold Climate control system
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior. It
is the most effective when the windows and sun­
roof are closed. If there is a build-up of heat in­
side the vehicle , ventilation can help to speed up
the cooling process.
In all heating mode functions except
defrost, the
blower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture.
Condensation from the cooling system can drip
and form a puddle of water under the vehicle.
This is normal and does not mean there is a leak.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
The air pollutants filter must be changed at the
intervals specified in your Warranty & Mainte­
nance booklet, so that the air conditioner can
properly work.
If you drive your vehicle in an area with high air pollution , the filter may need to be changed
more frequently than specified in your Audi War­
ranty
& Maintenance booklet. If in doubt, ask
your authorized Audi Service Advisor for advice.
Key coded settings
The climate control settings are automatically
stored and assigned to the remote control key
that is in use .
.8, WARNING
Reduced visibility is dangerous and can cause
accidents.
- For safe driving it is very important that all
windows be free of ice, snow and condensa­
tion.
68
- Completely familiarize yourself with the
proper use and function of the heating and
ventilation system and especially how to de­
fog and defrost the windows .
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshield first, using the heat­
ing and ventilation system . The washer solu­
tion may freeze on the windshield and re­
duce visibility .
(D Note
-If you suspect that the air conditioner has
been damaged, switch the system off to
avoid further damage and have it inspected
by a qualified dealership.
- Repairs to the Audi air conditioner require
special technical knowledge and special
tools. Contact an authorized Audi dealer for
assistance.
@ For the sake of the environment
By reducing the amount of fuel you use, you
also reduce the amount of pollutants emitted
into the air.
(D Tips
-Keep the air intake slots (in front of the
windshield) free from ice, snow and debris
in order to maintain the proper function of
the climate control system.
- The energy management system may switch
the seat heating* or rear window defroster
off temporarily. These systems are available
again as soon as the energy balance has
been restored.
- Air escapes through vents under the rear
window. When placing items of clothing on
the luggage compartment cover, ensure
that the openings are not covered.

ten if you drive most ly short distances, operate
the vehicle in dusty areas or under predom inantly
stop-and-go traffic condit ions, or have your vehi­
cle where temperatures rema in below freezi ng
for extended periods.
Detergent addit ives in the o il w ill make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
cha nge the oil mo re often than recommended .
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
qu ired, we stro ngly recommend that you have
your oil changed by an autho rized
Aud i deale r or
a qualif ied se rvice stat ion.
If you choose to change your o il yourself, please
note the fo llowing important information :
A WARNING
To reduce the ris k of persona l inju ry if yo u
must c han ge the engine oil in your ve hicle
yo urself:
- Wea r eye p rotection .
196
-
-To reduce t he risk of burns from hot engine
oil, let the engine coo l down to the touch.
- W hen removing the o il drain p lug with your
fingers, stay as far away as possib le. Always
keep your forearm parallel to the ground to
he lp prevent hot oi l from running down your
arm .
- Dra in the oil into a c ontainer designed for
this purpose, one la rge enough to hold at
least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it we ll out of
the reach of chi ld ren .
- Continuous contact w it h used eng ine oi l is
ha rmf ul to your skin. Always protect you r
skin by washi ng oil off tho roughly wi th soap
a nd wate r.
(D Note
Never mix oil additives with your engine oil.
These additives can damage your e ngine and
adverse ly affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
- Before changi ng your oil, first make su re
you know where you ca n prope rly dispose of
the used oil.
- Always dispose of used eng ine oil properly.
Do not d ump it on garden so il, wooded
areas, in to op en st reams o r down sewage
drai ns.
- Recycle used engi ne oil by taking it to a used
eng ine oi l collect ion fac ility in yo ur area, o r
c ontact a service station.
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.
The cooling system is sealed and genera lly re­
q u ires little attention.
The cooli ng sys tem has been filled at the f actory
wi th a permanent coolan t which does not need to
be changed. The coolant consists of a mixtu re of
jll,,

M N
i? co ,...., \!) 1.1"1
N 1.1"1 ,....,
specially conditio ned water an d the manu fa ctu r­
er's glycol-basedcoolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­
els; 60% for Canadian models). This m ixture both
assures the necessary frost protection and pro­
tects meta l components in the engine's cooling
system from corrosion and scal ing . It also raises
the boiling point of the coolant.
Do not reduce the concentration of the coolant in
the summer by adding plain water .
The p ropor­
tion of coolant addit ive must be at l east 50 %
but n ot mor e th an 60 %
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant cou ld
freeze and damage the vehicle heating and en­
gine cooling system.
F or yea r-round driving, antifreeze is added at the
factory fo r temperatures dow n to:
- -31°F(-35°C)USA
- -40 °F ( - 40 °C) Canada.
If you must add coo lant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
¢ &. in Working in the engine compart­
ment on page 191.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant addit ive in your
vehicle is suffic ient to meet the cli mate con­
dit ions. This is especially important if you
li ve in a region where the win ter is extreme­
l y co ld. If ne cessary, i ncrease the proport ion
of coo lant add itive to 60%.
- When adding coolant a ddit ive to you r cool ­
i ng system, remember:
- We recommend using only coolant addi­
tive Gl2++ or Gl3 for your ve hicle. This
coolant additive is ava ilable at authorized
Audi dea lers. Other types of ant ifreeze can
significant ly reduce co rrosion protection.
Checking and Fillin g
The resulting corrosion can ca use a loss o f
coolant and serious engine damage.
- Do not add any type of rad iator le ak sealan t
to your vehicle's engine coolant. Adding ra­
diator repai r fluid may adverse ly affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Lim ited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.
