Opening and closing

Press both of the outer buttons on the con-
trol unit > page 30, fig. 25 until the yellow
LED (2) turns off and the green LED @ blinks.
This procedure clears the standard codes that
were set at the factory and does not need to
be repeated again to program the other but-
tons.
Briefly press the button in the control panel
that you want to program.
Wait until the yellow LED (2) blinks. The pro-
gramming mode is active for five minutes.
Go in front of the vehicle with the original re-
mote control transmitter for the system that
you are programming to the control panel
button.
Programming the button: step 2 at the
radiator grille
6. Hold the remote control transmitter at the
vehicle radiator grille > fig. 26.
Now press the remote control transmitter
until the turn signals on your vehicle blink.
This can take up to 30 seconds.
If the emergency flashers blink three times,
the programming was successful. If the
emergency flashers only blink one time, the
five-minute time limit for programming has
expired or the programming was unsuccess-
ful. Repeat the programming procedure
starting from the third step or change the
distance to the radiator grille.
If the garage door or other systems do not
open with the HomeLink buttons even if the
programming was successful, the system
may use a rolling code instead of a fixed
code. You must also then perform rolling
code programming > page 31.
The other two buttons in the control panel can be
programmed using the instructions given above.
Start with step 3.
Deleting button programming
The programmed buttons cannot be deleted indi-
vidually. They must be deleted all at once. Repro-
gram the buttons if necessary.

unit until the yellow LED (2) turns off and the
green LED (@ blinks.
Reprogramming buttons
> Switch the ignition on.
> To reprogram an individual button, press the
desired button until the green LED (@) turns off
and the yellow LED (2) starts to blink (after ap-
proximately 20 seconds). Release the button
immediately. The programming mode is active
for five minutes.
> Continue with step 5.
@ Tips
— The distance needed between the remote
control transmitter and the garage door
opener module in the radiator grille
=> fig. 26 depends on the system you are
programming.
— Depending on the system model, you may
need to release the button on the remote
control transmitter while it is programming
and press it again. Hold every position you
try when programming for at least 15 sec-
onds before trying a new position. Keep an
eye on the vehicle turn signals while doing
this.

Driving

short time. If this is the case, repeat the starting
procedure after approximately 30 seconds.

ZA\ WARNING
— To reduce the risk of asphyxiation, never al-
low the engine to run in confined spaces.
— Never turn off the engine before the vehicle
has come to a complete stop.
— The brake booster and power steering only
work when the engine is running. If the en-
gine is off, you have to use more force when
steering or braking. The fact that you cannot
steer and brake as usual may increase the
risk of accidents and serious injuries.

© Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This re-
duces unnecessary emissions.
@ Tips
— Some noise after starting the engine is nor-
mal and is no cause for concern.
— If you leave the vehicle with the ignition
switched on, the ignition will switch off af-
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Stopping the engine
> Bring the vehicle to a full stop.
> Press the [START ENGINE STOP

button.
Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving at speeds starting at
4 mph (7 km/h). To stop the engine, press the
START ENGINE STOP] button twice in a row or
press and hold it one time.

Z\ WARNING
— Never turn off the engine before the vehicle
has come to a complete stop. Switching it
off before the vehicle has stopped may im-
pair the function of the brake booster and
power steering. You may need to use more
force when braking or steering. Because you
cannot brake and steer as you usually would,
this could lead to accidents and serious inju-
ries.
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. If you
do not do this, the engine could be started
and electrical equipment such as the power
windows could be activated. This can lead to
serious injuries.
— For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally.

@) Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
(i) Tips
For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again auto-
matically or it may continue to run, even if the
ignition is switched off.

Parking aid

Parking aid
Introduction
Applies to: vehicles with rear parking system/parking system
plus
Depending on the vehicle equipment, various
parking aids will help you when parking and ma-
neuvering.
The rear parking system is an audible parking aid
that warns you of obstacles behind the vehicle
=> page 81.
The parking system plus assists you while park-
ing by audibly and visually warning you of objects
detected in front of and behind the vehicle
=> page 81.
The rearview camera shows the area behind the
vehicle in the Infotainment system display. The
lines in the rearview camera image help you to
park or maneuver > page 82.

ZA WARNING
— Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is always
responsible when entering or exiting a park-
ing space and during similar maneuvers.
— Please note that some surfaces, such as
clothing, are not detected by the system.
— Sensors and cameras have blind spots in
which people and objects cannot be detect-
ed. Be especially cautious of small children
and animals.
— The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody. The park-
ing system may be impaired as a result.
Have an authorized Audi dealer or author-
ized Audi Service Facility check their func-
tion.
— Make sure the sensors are not obstructed by
stickers, deposits or other materials. If they
are, the sensor function could be impaired.
For additional information on cleaning, see
=> page 262.

@) Note
— Some objects are not detected or displayed
by the system under certain circumstances:
— objects such as barrier chains, trailer draw
bars, vertical poles or fences
— objects above the sensors such as wall ex-
tensions
— objects with certain surfaces or structures
such as chain link fences or powder snow
— If you continue driving closer to a low ob-
ject, it may disappear from the sensor
range. Note that you will no Longer be
warned about this obstacle.
— Maintain enough distance from the curb to
reduce the risk of damage to the rims.
@) Tips
— The system may provide a warning even
though there are no obstacles in the cover-
age area in some situations, such as:
— certain road surfaces or when there is tall
grass
— external ultrasonic sources such as from
cleaning vehicles
—in heavy rain, snow, or thick vehicle ex-
haust
— We recommend that you practice parking in
a traffic-free location or parking lot to be-
come familiar with the system. Practice
parking in good light and weather condi-
tions.
— You can change the volume of the signals.
— What appears in the display is slightly de-
layed.
— The sensors must be kept clean and free of
snow and ice for the parking aid to operate.

— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Allow the engine to cool.
— Keep children away from the engine com-
partment.
— Never spill fluids on a hot engine. These flu-
ids (such as the freeze protection contained
in the coolant) can catch fire.
— Avoid short circuits in the electrical system.
— Never reach into the radiator fan. The fan is
temperature-controlled and can turn on
suddenly, even when the ignition is switched
off.
— Never open the hood when there is steam or
coolant escaping from the engine compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
— Never open the cap on the coolant expan-
sion tank when the engine is warm. The
cooling system is under pressure.
— To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a

circumstances. This increases the risk of
burns.
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-

nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“P” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and ties, tie back long
hair, and make sure all clothing fits close
to the body to to reduce the risk of any-
thing becoming caught in engine compo-
nents.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to exhaust and chemi-
cals to as short a time as possible.

— Before changing the engine oil, make sure
you can dispose of the used engine oil cor-
rectly.
— Engine oil must always be disposed of cor-
rectly. Do not dump it in the yard, in the for-
est, or in open water, river channels, or sew-
ers.
— Have your used engine oil recycled by bring-
ing it to a used oil collection site or contact
a gas station.
Cooling system
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac-
tory. This coolant must not be not changed.
The coolant level is monitored through the B in-
dicator light > page 17. However, occasionally
checking the coolant level manually is recom-
mended.
Coolant additive
The coolant additive is made of anti-freezing and
corrosion protection agents. Only use the follow-
ing coolant additives. These additives may be
mixed with each other.
