(D Tips
- The distance needed between the remote
control transmitter and the Homelink mod­
ule in the radiator grille
¢fig. 29 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
-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. Because you cannot
steer and brake as you usually would, this
could lead to accidents and serious injuries.
(D 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.
{D) 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.
.,. Move the selector lever into the P position .
... Press the
I START ENGINE STOPI button
¢ page 57, fig. 60.
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 switch the engine
off, press
the
! START ENGINE STOPI button twice in a row
briefly or press and hold for longer than two sec­
onds.
_&. WARNING
- Never turn off the engine before the vehicle
has come to a complete stop.
58
- Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine
off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and braking capa­
bility is not available, the risk of accidents or
. . . . mJunes increases.
- 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.
- 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 temperature rises as the
result of heat buildup or if the engine is al­
ready warm and the engine compartment is
also heated by the sun's rays.
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after th@ 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.

parking aids will help you when parking and ma­
neuvering.
The
rear park ing system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 83.
The parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the veh icle
¢ page 83.
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 84. The parking sys­
tem plus functions are also available
¢ page 83.
& 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 leaving 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 gr ille, 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.

(D 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 th is obstacle.
- Keep enough distance from the curb to re­
duce 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 . When doing
this, there should be good light and weath­
er conditions.
- 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 park aid to operate .

caping coolant and steam by covering the
coolant tank cap with a large, thick cloth .
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap .
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­
haust system or hot engine components .
The ethylene g lycol in engine coolant can
catch fire under certain circumstances.
- The coolant add itive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can sw itch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine. If this is the case, do not
cont inue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­

Consumer information
scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
gine and transmission parts which an owner can
perform .
Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and other
equipment available to specially trained work­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty.
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for
upholding a possible warranty claim made within
the warranty period.
Above all, operational safety can be adversely af­
fected, creating unnecessary risks for you and
your passengers.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any other properly
equ ipped and qualified workshop. We strongly
urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­
nance and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly.
Performing limited maintenance yourself
The following pages describe a limited number of procedures which can be performed on your vehi­
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicable text and careful­
ly follow the instructions given. Always rigorously
observe the
WARNINGS provided.
Before you check anything in the engine com­
partment, always read and heed all WARNINGS

A WARNING
-
- Serious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when working
on the vehicle. Always follow commonly ac­
cepted safety practices and general com­
mon sense. Never risk personal injury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fully familiar with these
or other procedures with respect to the ve­ hicle, or are uncertain how to proceed.
- Do not do any work without the proper tools
and equipment. Have the necessary work
done by your authorized Audi dealer or an­
other properly equipped and qualified work­
shop.
- The engine compartment of any motor vehi­
cle is a potentially hazardous area. Never
reach into the area around or touch the radi­
ator fan. It is temperature controlled and
can switch on suddenly - even when the en­
gine is off. The radiator fan switches on au­
tomatically when the coolant reaches a cer­
tain temperature and will continue to run
until the coolant temperature drops.
- Always switch off the ignition before anyone
gets under the vehicle.
- Always support your vehicle with safety
stands if it is necessary to work underneath
the vehicle. The jack supplied with the vehi­
cle is not adequate for this purpose and
could collapse causing serious personal in­
Jury.
- If you must work underneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that
the engine cannot be started.
- Always make sure the transmission selector
lever (automatic transmission) is in P (Park
position) and the park brake is applied. ..,
