80 On the road
the distance between your vehicle and
other vehicles.
- For safety reasons, the cruise control
should not be used in the city, in stop­ and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
planing) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off. The other cruise control functions re­
main active as long as the indicator light
II (US models) !Iii (Canadian models)
is on.
The brake lights illuminate as soon as the
brakes decelerate automatically.
Changing speed
Applies to vehicles: with cru ise control
.,. To increase/decrease the speed in incre­
ments, tap the lever in the
010 direction
¢ page 79, fig . 86
.,. To increase/decrease the speed quickly, hold
the lever in the
010 direction until the de­
sired speed is displayed.
You can also press the accelerator pedal down
to increase your speed, e.g . if you want to
pass someone. The speed you saved earlier
will resume as soon as you release the acceler­
ator pedal.
If , however, you exceed your saved speed by
6 mph (10 km/h) for longer than 5 minutes,
the cruise control will turn off temporarily.
The green symbol
II (US models) !Iii (Cana- dian models) in the display will go out but the
saved speed remains the same.
Presetting your speed
Applies to vehicles: with cruise cont
rol
You can preset your desired speed while the
vehicle is not moving.
.,. Switch on the ignition.
.,. Pull lever into position@¢
page 79,
fig. 86.
.,. Press the lever in the 0 or 0 direction to
increase or decrease your speed.
.,. Release the lever to save that speed.
This function makes it possible, for example,
to save the speed you want before driving on
the highway. Once on the highway, activate
the cruise control by pulling the lever toward
@.
Switching the system off
Applies to vehicles: with cruise control
Temporary deactivation
.,. Press the brake pedal, or
.,. Press the lever into position@(not clicked
into place)
~ page 79, fig . 86, or
.,. Drive for longer than 5 minutes at more
than 5 mph (10 km/h) above the stored
speed.
Switching off completely
.,. Press lever into position @ (clicked into
place), or
.,. Switch the ignition off .
The system retains the saved speed if you de ­
activate the cruise control temporarily. To re­
sume the saved speed, release the brake ped­
al and pull the lever to position @.
Switching the ignition off erases the saved
speed .
A WARNING
-You should only return to the saved speed
if it is not too fast for the current traffic
conditions -risk of an accident!

Automatic Transmission 107
To keep shifting using the shift paddles,
move the selector lever to the right out of
the D/S pos ition.
When accelerating, the transmission does
not
automatically shift to the next gear shortly
before the maximum permitted engine RPM is
reached.
If you have se lected a lower gear than the cur­
rent one, the automatic transmission will shift
down only when the engine will not be over ­
revved.
With kick-down , the transmission shifts into a
lower gear depending on speed and engine
RPM.
(D Tips
Tiptronic is inoperat ive when the transmis­
sion is in the fa il-safe mode.
Kick-down
Kick-down enables maximum acceleration.
When you depress the accelerator peda l be­
yond the resistance point, the automatic
transmission downshifts into a lower gear, de­
pending on vehicle speed and engine speed .
The upshift into the next higher gear takes
place once th e maximum specified engine
speed is reached .
A WARNING
Please note that the drive wheels can spin
if kick-down is used on a smooth slippery
road - there is a risk of skidd ing.

lect gear again
Press the brake pedal and select the desired
selector lever position again . You can then
continue driving.

conservatively

188 Intelligent technology
Anti-slip regulation (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerat e and drive up hills .
Electronic differential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive powe r to the o ther wheels.
This function is not availab le at higher speeds.
I n extreme cases , ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll sw itch on aga in au­
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steering*, ESC also
he lps to stabilize the stee ring in critical s itua­
tions.
Selective wheel torque control
Selective wheel torque control is used when
driving on curves . The front wheel on the in­
side of the curve o r both wheels on the inside
of the curve are braked selective ly as needed.
This a llows more prec ise driving in curves. The
appl icable system may no t activ ate when driv­
ing in wet or snowy condi tions .
A WARNING
- The ESC and its integrated systems can­
not overcome the lim its posed by natural
physical laws. This is especia lly impor- tant on slippery or wet roads
. If the sys­
tems beg in acting to stabilize your vehi­
cle, you should immediately change your
speed to match the road and traffic con­
ditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Do ing so will increase the risk
of a loss of veh icle contro l, collision and
serio us pe rsonal inj uries.
- Always ad apt your speed to road, traffic
a nd wea ther conditions. The risk of los­
ing con trol of the vehicle increases when
driving too fast, especially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead . The ESC and its integrated sys­
tems cannot a lways prevent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistan ce sys tems that cannot al­
ways he lp to re duce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
all four wheel s are equipped with identi­
c al tires . D iffe ren t tire sizes can lead to a
reduction in engine power.
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator lig ht

particular require a great deal of energy. If
you notice, for example, that the heated seats* or the heated rear window are not
heating, they have been temporarily cut back
or switched off. These systems will be availa­ ble again as soon as the energy balance has
been restored.
You will also notice that engine idle speed has been increased slightly. This is normal and not
a cause for concern . By increasing engine idle
speed the additional energy required is gener­
ated and the battery is charged.

198 Driving and en vironm ent
_& WARNING
The temperature o f the exhaust system is
high, both when driving and after stopping
the engine .
- Never touch the exha ust tail p ipes once
they have become hot. This could result in burns .
- Do not park or operate the veh icle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold , exhaust p ipes, catalytic con ­
verte r or heat shie lds. D uri ng d riving, the
substance used for undercoating cou ld
over heat and cause a fire .
(I) Note
- Be aware that just one tank filling with
l eaded fuel will already seriously de­
grade the perfo rmance of the cata lytic
conve rter.
- Do not exceed the correct engine oil leve l
¢page 215.
- Do not d rive until the fuel tank becomes
completely empty. The eng ine could mis­
fire. Unburned f uel could a lso ge t in to
t h e exhaus t sys tem and this could cause
the ca talyt ic converte r to ove rheat.
- Do no t switch off the ign ition wh ile the
vehicle is moving.
- Do no t continue to operate yo ur vehicle
u nder these condi tions, as otherw ise fuel
can reac h the catalytic converter . This
could result in overheating of the co n­
verter, req uiring its replacement.
- To assure efficient operation of the Emis ­
sion Control System :
- Have your veh icle maintained properly
and in accordance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir the function of the em
ission cont ro l
system and could lead to damage .
~ For the sake of the env ironment
Even when the Emiss ion Con trol Sys tem is
operat ing proper ly, the exha ust gas can
have a sulfur-li ke ex haust gas smell under
some ope rat ing states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or fil ling the tank with lead -free super
grade gasoline .
Shutting down vehicle
If you would like you r vehicle to remain inop­
erative for a longer per iod of t ime, contact an
Audi o r other spec ia lized dealer. They can ad­
v ise you on ne cessa ry precautions e .g. co rro­
s io n preven tion , maintena nce and s to rage.
Pay a ttent ion to addi tional in fo rmat ion con­
cerning the battery. Refer to

Operate your vehicle
economically and
minimize pollution
General
Your p ersonal style of driving will determine
the economy of your vehicle , as well as ex ­
haust and nois e le ve ls .
Fu el economy, environmenta l impact, and
wear on your engine , brakes and tires largely
depend on three factors:
- your personal d riving style
- operati ng conditions
- technical limitat ions
If you an tic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt io n by 10 -15 percent . This sec ­
t ion w ill give you some tips on how you can
help the e nvir onment and your pocketbook .

@ Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehi­
cle load and speed, road and weather con­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
~ Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
celerating. If you anticipate what is going to happen next, you will need to brake less and,
thus , accelerate less . Let the vehicle coast
whenever possible -for example when you see
that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
~ Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en­
gine noise increase disproportionately at high
speeds . If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
~ Shut the engine off when you are not driving
the vehicle.
Driving and environment 199
~ Do not warm up the vehicle by letting the
engine run at idle.
It makes sense to shut off the engine in traffic
jams , when waiting for trains to pass at rail­
road crossings, or at traffic lights that have
long waits on red. Turning the engine off for
just 30 -40 seconds saves more fuel than is
burned starting the engine again.
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in over­
heating or other damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
~ Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you fill your tank.
The amount of oil used is related to engine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven .

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 specially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with anticorros 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 cooling 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
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi ­
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 ° F ( - 40 °C) Canada.
I f you must add coo lant, use a mixture of wa­
ter and coolant addit ive. Mixing the coolant
additive with distilled water is recommended.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~.&.
in Working in the engine
compartment on page 211.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
Checkin g and fillin g 217
your vehicle is sufficient to meet the cli ­
mate conditions. This is especia lly impor­
tant if you live in a region where the win­
ter is extremely co ld. 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 G12++ or G13 (check the label)
for your vehicle . This coolant additive is
avai lable at authorized Audi dealers .
Other types of antifreeze can signifi­
cantly reduce corrosion protection. The resulting corrosion can cause a loss of
coolant and serious 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 Veh icle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

with an e lectric coolant level sensor.
When the coolant level is too low, the warning l ight in the Auto-Check System
9 page 15 w ill
illum inate unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time .
Coolant loss
Coolant loss may indicate a le ak in the 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
s ealed 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 followi ng these
steps .
- Turn off the engine and allow it to coo l
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 carefu lly in
a counter-clockwise direction w hile ap­
plying light, downward pressure on the
top of the cap . -
To avoid being burned, do not spi ll anti­
freeze or coolant on the exha ust system
or hot engine parts. Under certain cond i­
tions, the ethylene glycol in engine coo l­
a nt can catch fire.
(D Note
Do not add any type of radiator leak sea l­
ant to your veh icle's engine coolant. Add­
i ng radiator repair fluid may adverse ly af­
