126 Automatic transmission
8_ WARNING
-Unintended vehicle movement can cause
serious injury .
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running,
activate the parking brake and move the
selector lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into
R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system .
- To preven t the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake.
- Never hold the vehicle on an incline with
a slipping clutch . The clutch opens auto­
matically when it becomes too hot from
the overload. An indicator lamp
[O] illu­
minates and a driver message appears
<=:> page 128when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
r:::> page 231 . Otherwise, any increase in engine speed may set the vehicle in mo­
tion, even with the parking brake ap­
plied.
(D Note
- When stopping on an incline , do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake pedal to prevent the vehicle from rolling .
- Allowing the vehicle to roll when the en ­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances.
@ Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er's safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
Hill descent control is activated when these­
lector lever is in D /S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations. It may still be nec­
essary to adjust the speed with the brakes .
Hill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
When the speed is set in the cruise control
system
r:::> page 95, hill descent control is also
activated.
A WARNING
-
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all

Homelink
Universal remote
control
Description
Applies to vehicles: with Home link
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
With Home Link, you can control devices such
as the garage door, security systems, house
lights , etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to rep lace
three different remote controls from dev ices
in your home with one universal remote. This
feature works for most garage door and exte­
rior door motor signals. Programming the in­
dividual remote control for your remote con ­
trol takes place near the center of the radiator
grille. There is a control module attached at
this location .
A one-time programming of the sensor must be performed before you are able to use sys­
tems with Homelink. If the system does not activate after performing the one-time pro­
gramming, check whether the system uses a rolling code¢
page 138 for vehicles without
the MMI*.
& WARNING
-
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as requ ired by federa l safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
-A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Using a garage door
opener without these features increases
risk of serious injury or death.
Homelink 135
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, th is can overstrain motor and
damage its electrical components - an
overheated mo to r i s a fire hazard!
- To avoid possib le injuries or property
damage, please always make abso lutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) rein­
forces driver safety. It reduces the risk of slip ­
ping and improves driving stability. ESC de­
tects critical s ituations such as the vehicle
Intelligent technology 197
oversteering and understeering or the whee ls
spinning . The vehicle is stabilized by applying
the brakes or reducing eng ine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL), dy­
namic steering*, hill descent assist and selec­
tive wheel torque control.
Anti-lock brake system (ABS)
ABS prevents the whee ls from locking up
when braking . The vehicle can still be steered
even during hard braking. App ly steady pres­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations . You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels beg in to sp in and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hill s.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the othe r whee ls .
T his function is available up to about 78 mph
(125 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au­
tomatically when conditions have returned to
normal.

206 Driving and en vir onm ent
Catalytic converter
Appl ies to vehicles: with gasoline e ngin e
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.. Always use lead-free gasoline i=> page 222,
Gasoline .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 236, Adding engine oil 'l=r. .
.. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalyti c converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr itically
important for the l ife of the cata lytic convert­
e r and proper functioning of the engine.
A WARNING
T he temperature o f the exhaust system is
high, both when driving and after stopping
the engine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle 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
verter or heat sh ields . During driving, the
substance used for u ndercoating cou ld
overheat and cause a fire.
@) Note
- Be aware that just one tank f illing with
leaded fuel will already seriously de­
grade the perfo rmance of the cata lytic
conve rter. -
Do not exceed the correct engine oil level
i=>page 236.
-Do not drive until the fue l tank becomes
completely empty . The engine co uld m is­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is mov ing .
- Do not continue to ope rate your vehicle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis­
sion Control System:
- Have you r vehicle maintained p roperly
and in accordance w ith the service rec­
ommendations in your Warranty & Maintenance book let.
- Lack of prope r maintenance as we ll as
improper use of the vehicle wi ll impair
the function of the em ission contro l
system and could lead to damage.
@) For the sa ke of the en vironment
Even when the Emission Control System is
ope rat ing properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Usi ng a different brand of fuel may help,
or f illing the tank with lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with diese l eng ine
The diesel part icu late filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil­
te r cleans itself automat ica lly unde r no rma l
dr iv ing cond itions . If the filte r cannot clean it­
self (for example, because you are on ly driving
short distances), the filter becomes clogged
with soot and the
II symbol for the diesel
particulate filter i lluminates
i=> page 34. ..,.

238 Check ing and filling
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adversely affect your Audi Limit­
ed New Vehicle Warranty.
@) For the sake of the environment
- Before changing your oi l, f irst make sure
you know where you can properly dispose of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden so il, 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 sea led and generally re­
q ui res little attention .
The cooling system has been filled at the fac­
tory with a pe rmanent coolant which does not
need to be changed. The coolant consists of a
mixture o f spec ia lly condi tioned water and the
manufacturer's glycol -basedcoolant addi -
tive G l3 antifreeze with anticorrosion 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
i ng po int of the coo lant .
Do not red uce the concentration of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add iti ve mu st be at
least 50 % but not more than 60 %
to main­
tain antifreeze protection and cooling efficie n­
cy.
If t he coolant frost protect io n is too low,
the coo lant cou ld freeze and damage the veh i­
cle heating and engine cooling system. F
or year -ro und driving, antifreeze is added a t
the factory for temperatures down to :
- -31°F(-35° C)USA
- -40°F ( -40°C) Canada.
If you must add coolant, use a mixture of wa­
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended .

Before you c hec k anyth ing in the engine
compartment, a lways read and heed a ll
WAR NIN GS~ .&.
in Working in the engine
compor tment on page 231 .
(J;) Note
-Before winter sets in, have the coo lant
checked to see if the coolant additive in
yo ur vehicle is sufficient to meet the cli­
mate condi tions . This is especia lly impor ­
tant if you live in a region where the win ­
ter is extreme ly co ld . If necessary, in­
crease the p roportion of coo lant add itive
to 60%.
- When adding coolant additive to yo ur
cooling system, remember :
- W e r ecommend using o nly coola nt ad­
d itive G l2++ or Gl3 for your veh icle.
T his coolan t additive is av ail ab le a t au­
thor ized Audi dealers. O ther types of
antifreeze can significant ly reduce cor ­
rosion protection . The resulti ng cor ro­
sion can cause a loss o f coolant and se­
rious engine damage.
- Do not add any type of rad iator leak seal ­
ant to your vehicle 's eng ine coolant.
Add ing radiato r repair flu id may adverse­
ly affect the function and performance of
your cooling system and co uld resu lt in

blink until you add coo lant and the level has
been restored to normal. Even though there is
a n elec tric coolant leve l sensor, we s till rec­
ommend you chec k the coolant leve l from
time to time .
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool-

@ Tips
-Do not operate the compressor for more
than 12 minutes continuously, otherwise it can overheat. Once the compressor has
cooled, you can continue to use it.
- If sealant has spilled out, let it dry and
then you can remove it by peeling it away
