The instrument illumination (for dials and
needles) turns on when the ignition is on
and the vehicle lights are turned off. As
the daylight fades, the illumination of the
dials likewise dims automatically and wil l
go out completely when the outside light
is very low. This feature is meant to rem ind
you to switch on the headlights when out­
side light conditions become poor.
Engine coolant temperature gauge
The engine coolant gauge CD¢ page 11, fig. 3
only works when the ignition is on. To prevent
damage to your eng ine, please note the fol­
l owing important points:
Engine cold
If only the LEDs at the bottom of the gauge
turn on, the eng ine has not reached operating
temperature yet . Avoid high engine speeds,
heavy engine loads and heavy throttle applica­
tions.
Normal temperature
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving cond i­
t ions. The LEDs higher up may turn on when
the engine is under heavy load or the exterior
temperature is high. This is no need to worry
as long as the. warning light in the instru­
ment cluster does not illuminate . If the LEDs
in the upper area of the display and the indica­
tor light . in the instrument cluster display
turn on, the coolant temperature is too high
¢page 16.
A WARNING
-Always observe the warn ing in
¢ page 222, before opening the hood
and checking the engine coolant level.

12 Instrum ent s and w arn ing /indic ato r light s
-Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself . Let the engine
cool off first until you can no longer see
o r hear steam or coo lant escaping.
@ Note
- Mounting additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the rad iator . At h igh outside
temperatures or high eng ine load, the
engine could overheat.
- The front spo iler has been designed to
proper ly distribute the cooling air when
t h e ve hicle is moving.
If the spoiler is
dam aged, th is co uld red uce the cooling
effect and the engine co uld then over­
heat . Ask your authorized Audi dea ler for
assistance .
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine RP M drops be low 1,500, yo u should
downshift to the next lower gear. The red a rea
at the end of the sca le indicates maximum
perm iss ib le engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position D/S (Drive) or ease
your foot off the accelerator pedal.
(D Note
The tachometer needle should on ly br iefly
be in the red zone: you could damage your
engine! The beginn ing of the red zone var­
ies depending on the engine .
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.
Fuel gauge
The fuel gauge only works when the ignition is
on .
If the fuel level d rops below 2 . 6 ga llons (10 liters), the bottom LED turns red and the
indicator light
ll'J turns on r=> page 22. The
bottom LED blinks red when the fuel level is
very low.
T he possible range based on the current fuel
level is shown in tab@r=>
page 24, fig . 4 .
(D Note
Never run the tank completely dry. An ir ­
r egular supply of f uel can cause engine
misfiring and fuel could enter the ex ha ust
system . The catalytic converter could then
overheat and be damaged.

16 Instrum ent s and w arn ing /indic ato r light s
-If the brake warning/indicator light does
not go out after a few seconds and the
park ing brake is released, or lights up
wh ile you are driving, the fluid level in
the brake fluid reservoir is too low .
If you
believe that it is safe to do so, proceed
immediately at low speed to the nearest
authori zed Aud i dealer o r qualified repa ir
f acili ty and have the brake system in­
spected.
- Always keep in m ind that after several
brake applicat ions, yo u will need greater
pressure on the brake peda l to stop your
vehicle. Do not re ly on strained brakes to
respond with maxim um stopp ing power
in critical situations. You must allow for
increased brak ing distances . The extra
distance used up by fad ing brakes could
lead to an acc ident.
PARK/( ®) Electromechanical parking brake
The warning/indicator light monitors the
electromechanical parking brake.
If the indicator light . (USA models)/ .
(Canada models) turns on, the park ing brake
was set .
• (U SA models) • (Canada models ) Cau­
tion: Vehicle pa rked too steep
If the indicator light blinks and the message
appears, there is not eno ugh braking power to

Warm and cold Climate controls
Description
App lies to vehicles: with three -zone cl imate contro l or
four -zone a uto mat ic climate contro l
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
sunroof* are closed . If the temperature inside
the parked veh icle becomes very warm, open­
i ng the w indow br iefly will speed up the cool­
ing process.
In all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
drip and form a puddle of wate r under the ve­
h icle. This is normal and does not mean there
is a leak .
Pollutant filt er
The pollutant filter removes pollutants such
as dust and po llen from the air.
The air pollutants filter must be changed at
the intervals specified in your Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work .
If you drive your vehicle in an area with high
a ir pollution, the filter may need to be
changed more frequently than specified in
your Aud i Warranty
& Ma intenance booklet. If
i n doubt, ask your authori zed Audi Service Ad­
visor for adv ice.
K ey coded settings
Three-zone climate control: T he b lower set­
ting and air d istribution are stored automati­
cally and ass igned to the remote control key
that is in use .
Four-zone automatic climate control: The cli­
mate contro l settings are automatica lly stor­
ed and assigned to the remote control key
that is in use .

A WARNING
-
Reduced visibi lity is dangerous and can
cause acc idents .
- For safe driving it is very important that
all windows be free of ice, snow and con­
densat ion.
- Comp letely fam il iarize yourse lf with the
proper use and funct ion of the heat ing
a nd ventilation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer system in freez ing weathe r unt il you
have wa rmed the windshie ld first, using
the heating and ventilation system. The
washer sol ution may freeze on the wind­
shie ld and red uce visibi lity.
CJ) Note
- If you s uspect that the air conditioner
has been damaged, switch the system
off to avoid furt her damage and have it
inspected by a qualified dea lership .
- Repairs to the Audi air conditioner re­
quire specia l technical know ledge and
special tools. Contact an authorized Audi
dealer fo r ass istance.
@ For the sake of the envi ronment
By reducing the amount of f uel you use,
you also red uce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lo ts ( in front of the
w indshield) free from ice, snow and de­
bris in order to maintain the proper func­
tion of the climate control system.
- The energy ma nagement system may
switch the seat heating* or rear window defroster off temporar ily. These systems
are available again as soon as the energy
balance has been restored .
- Air escapes through vents under the rear window. When plac ing items of cloth ing
on the luggage compartment cover, en­
sure that the openings are not covered.

climate control
system is switched off .
You can activate the residual heat function
whe n the ignition is off by pressing and hold­
ing the ~ button. The residua l heat from the
coolant is used to heat the vehicle interior .
The residual heat function switches off auto­
matically after about 30 minutes.
jA/C j Switching cooling mode on/off
The air is not coo led and humidity is not re­
moved when cooling mode is switched off.
T his can cause fog on the windows. Cooling
mode switches off automatically when the
outside temperature is be low zero .
1- 1 Switching recirculation mode on/off
In recircu lation mode, the air inside the vehi ­
cle is circu lated and filtered. This prevents the
unfiltered air outside the vehicle from enter­
ing the vehicle interior . We recommend
switching recirculation mode on when driving
through a tunnel or when sitting in traffic
¢ .&, .
The !AUTO I button or l switches recirculation mode off.

Starting the engine
"'Press the brake pedal c::> _&..
"'Pr ess the !START ENGINE STOPI button
c::> fig. 77. The engi ne will start.
"' It is possible that there will be a slight delay
when starting the engine for diesel vehicles
in colder temperatures. Therefore, you must
hold the brake pedal down until the engine
starts. The indicator lamp
Ii illuminates
when the engine is preheated.
If the engine should not start immedi ately,
the starting process is automatically stopped
after a short time . Repeat starting procedure.
Start-Stop-System*:
Note the information on c::> page 79, Start­
Stop-System.
A WARNING
- Never allow the engine to run in confined
spaces -danger of asphyxiation .
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- The brake booster and power steering
only work when the engine is running.
If
the engine is off, you have to use more
force when steering or braking. Because
you cannot steer and brake as you usual­
ly would, this could lead to crashes and
serious injuries.
-Avoid high engine rpm, full throttle and
heavy engine loads until the engine has
reached operating temperature - other­
wise you risk engine damage.
- The engine cannot be started by pushing
or towing the vehicle.
(D Tips
-After a cold engine is started, there may
be a brief period of increased noise be­
cause oil pressure must first build up in
the hydraulic valve adjusters. This is nor­ mal and not a cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off
On the road 75
after a certain period of time. Please
note that electrical equipment such as
exterior lights will switch off as well
when that happens.
Stopping the engine
"'Bring your vehicle to a complete stop.
"' Move the selector lever to the P or N posi ­
tion .
"'Press the
I STAR T ENGINE ST OP I button
c::> page 7 4, fig. 77.
Steering lock
The steer ing locks when you turn the engine
off using the
I STAR T ENGINE STOP I button
and open the driver's door. The locked steer­ ing helps prevent vehicle theft.
Emergency off
If necessary, the engine can be switched off
with the selector lever in the R or D/S posi ­
tion. The engine stops if you press the
I START ENGINE STOPI button at speeds below
6 mph (10 km/h).
A WARNING
-Never turn off the engine until the vehi­
cle has come to a complete stop.
- The brake booster and power steering
only work when the engine is running. If
the engine is off, you have to use more
force when steering or braking. Because
you cannot steer and brake as you usual­
ly would, this could lead to crashes and
serious injuries.
- For safety reasons, you should always
park your vehicle with the selector lever
in P. Otherwise, the vehicle could inad­
vertently roll away.
- After the engine has been switched off,
the radiator fan can continue to run for
up to 10 minutes -even with the ignition
switched off.
It can also switch on again
after some time if the coolant tempera­
ture rises as the result of a heat buildup
.
or if the engine is hot and the engine .,..

Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Air suspension*
When driving with a trai ler, activate the trailer
mode of the air suspension. Switch the air
suspension trailer mode on when you are tow­
ing a trailer. This will limit the regulation by
the air suspension while driving. Select in the
MMI:
! CARI function button> (C ar) * systems
control button > Vehicle settings > Air susp.:
towing > On .
Coolant temperature
The coolant temperature gauge¢ page 11
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds . Re­
duce your speed immed iately if the LEDs in
the top pa rt of the display turn on.
For more information about indicator lights,
refer to. ¢
page 16 .
A WARNING
Anyone no t properly restrained in a mov­
ing veh icle is at a much greater ris k in an
accident . Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi .
Trailer towing tips
Important to know
Your vehicle handles differently when tow ing
a trailer because of the addit ional weight and
d ifferent weight distribution . Safety, perform­
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
M N turning, stopping and backing up in an area 0
~ away from traffic. Keep practicing until you
~ have become comp lete ly fam iliar with the way 1.1'1 ,...., 1.1'1 ,....,
Trailer towing 207
your vehicle-trai ler combination behaves and
responds.
Backing up is difficult and requires practice .
Backing up with a trailer generally req uires
steering action opposite to that when backing
up your vehicle without a trai ler.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer , you wi ll need a larger than normal
turning rad ius.
When passing, remember that you cannot ac­
ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your trailer before chang­
ing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load ¢
page 292.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.,. App ly the foot brake .
.,. Have someone p lace chocks under both the
vehicle and the trailer wheels.
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load .
.,. Turn the wheels towards the curb.
.,. Apply the parking brake .
.,. Select the P selector lever posit ion.
When re starting after parking:
.,. App ly the foot brake.
.,. Start the engine.

A WARNING
Hot engine coolant can burn you.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
' Working in the engine compartment
Be especially careful whenever you work in
the engine compartment.
Whenever you must perform any work in the
engine compartment, for example checking
and filling different fluids, there is a risk of injury, burns and accidents. To prevent per­
sonal injury always observe the following
WARNINGS. The engine compartment of any
vehicle is a hazardous area
¢ ,&. .
A WARNING
To help avoid injury, before you check any­
thing under the hood:
- Turn off the engine.
- Switch off the ignition .
- Apply the parking brake.
- Move selector lever to P (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment.
- Never spill fluids on hot engine compo­
nents . They can cause a fire .
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly .
- Never open the coolant reservoir cap
when the engine is still warm . The cool­
ant system is pressurized and hot cool­
ant could spray out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir.
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri-
cal system is necessary: ..,_

228 Check ing and filling
- Always dispose of used engine oil proper ­
l y . Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.
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.
The cooling system is sealed and generally re­
qu ires little attention.
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of spec ially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with ant icorros ion addi­
tives (50% for USA models; 60% for Canadian
models). This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's coo ling system from
corrosion and scaling . It also raises the boil­
ing point of the coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water.
The
p ropo rtion of coolant add itive must be at
l e a st 50 % but not mo re th an 60 %
to ma in­
tain antifreeze protection and cooling efficien­
cy . If the coolant frost protect ion is too low,
the coo lant cou ld freeze and damage the veh i­
cle heating and eng ine cool ing system.
For year-round driving, antifreeze is added at
the facto ry for temperatures down to:
- -31°F(-35°C)USA
- -40 °F ( -40 °C) Canada.
If you m ust add coo lant, use a m ix tu re of wa ­
ter and coo lant addit ive . M ixing the coolant
additive with disti lled water is recommended .
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS~ &.
in Working in the engine
compartment on page
222 .
(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 especia lly impor­
tant if you live in a reg ion where t he win ­
t er is ex treme ly cold. If necessary, in­
crease the p roportion of coo lant add it ive
to 60% .
- When adding coolant addi tive to yo ur
c ooling sys tem, remembe r:
- We recommend us ing on ly coolant ad­
d itive G12++ or G13 (check the label)
for your vehicle . This coolant additive is
ava ilable at autho rized Aud i dea le rs.
Other types of antifree ze ca n sign ifi­
ca ntly reduce co rros io n protec tion. The
res ulting corrosion c an cause a loss of
coolant and serious engine damage.
- Do not add any type of r ad iator le ak seal­
ant to yo ur vehicle 's engine coolant .
Adding radiator repair flu id may adverse­
ly affect the function and performance of
your cooling system and cou ld resu lt in
damage not covered by your New Vehicle Limited Warranty.
Checking the engine coolant level
-
The engine coolant level can be checked with
a quick glance.
F ig. 1 91 Engi ne compartment: cover on the coola nt
expansio n tank

230 Check ing and filling
We recommend using on ly coo lant addi-
tive
Gl2++, Gl3 or in an emergency Gl2 +. Do
not use a different additive . In an emergency
use plain water unt il you can get the correct
additive and can restore the correct ratio. This
should be done as soon as possible .
If you have lost a cons iderable amount of
coolant, then you should add co ld antifree ze
and cold water only when the engine is co ld.
A lways use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolan t will be forced out through the
p ressure relie f valve in the cap when the en ­
gine becomes hot.
A WARNING
- The coo ling system is under press ure and
can get very hot. Reduce the risk of
sca lding from hot coolant by following
these steps.
- Turn off the eng ine and a llow it to cool
down.
- Protect your face, han ds and arms from
escap ing fl uid and steam by cover ing
the cap with a large, thick rag.
- Tur n the cap slowly and very c arefully
in a counter-clockwise d irect ion while
applying light, downward press ure on
the top of the cap .
- To avo id being burned, do not sp ill an ­
tifreeze or coolant on the exhaust sys ­
tem or hot engine parts. Under certain
conditions, the ethylene glyco l in en­
g ine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its or iginal container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clear ly marked "poison".
- Do not add coolant if the expansion tank
is empty. A ir could enter the cooling sys­
tem and damage the eng ine. If this is the case, do not cont
inue driving . Seek
professiona l assistance .
- Coo lant poll utes the environmen t and
co uld cause an engine fire . Excess cool­
ant will be forced out thro ugh the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an eme rgency, only wate r can be
added, the correct ratio between water
and antifreeze
c::> page 228 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be reused . A l­
ways d ispose of used coolant while observ­
i ng all environmental regulations .
Radiator fan
The radiator fan switches on automatically by
itself.
An a uxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operat ing condit ions .
After yo u switch the engine off, the auxi liary
fan can continue r unning for up to 10 minutes
- even w ith the ignition off . It can even switc h
on again later by itself
c::> .& , if
- the temperature of the engine coo la nt rises
due to the heat build- up from the engine in
the engine compartment, or
- the engine compa rtment heats up because
the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal injury nev­
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
