If necessary, the engine can be sw itched off
with the selector lever in the R, Dor S posi ­
tions . The engine stops if you press the
I START ENGINE STOP ! button at speeds below
6 mph (10 km/h).
A WARNING
- Never turn off the eng ine before the ve­
hicle has come to a complete stop . The
full function of the brake booster and the
power steering is not quaranteed. You
must use more force to turn or brake if
necessary. Because you cannot steer and
brake as you usual ly would, this could
lead to crashes and serious injur ies.
- For safety reasons, you should always
park your vehicle with the se lector lever
in P. Otherwise, the vehicle co uld inad­
vertent ly roll away .
- After the engine has been switched off, the radiator fan can continue to run for
up to 10 min utes - even with the ign it ion
switched off. It can a lso switch on aga in
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
compartment is addit ionally heated by
the sun's rays.
(D Note
Do not stop the engine immed iate ly afte r
ha rd or extended dr iving. Keep the engine
r u nning for approx imately two m inutes to
prevent excessive heat build-up.

Audi adaptive cruise control and braking guard 97
When approaching a moving vehicl e up ahead,
the adaptive cruise contro l system automati­
cally brakes to match that object's speed and
then maintains the stored distance.
If the ve­
hicle ahead accelerates, adaptive cruise con­
trol will also accelerate up to the stored
speed .
The higher the speed, the greater the distance
in yards (meters) ¢.&. . The
Distance 3 setting
is recommended .
The distances prov ided are specified values .
Depending on the driving situation and the
how the vehicle ahead is driving, the actual
distance may be more or less than these tar ­
get distances.
The various symbols for the time increments appear briefly in the information line @
¢
page 94, fig . 101 when you change the set ­
tings .
,::::::,_,::::::, ___ Distance 1: This setting corre-
sponds to a distance of 92 feet/28 meters
when traveling at 62 mph (100 km/h), or a
time interval of 1 second.
,::::::, __ ,::::::, __ Distance 2: This setting corre­
sponds to a distance of 118 feet/36 meters
when traveling at 62 mph (100 km/h), or a
time interval of 1.3 seconds .
,::::::, ___ ,::::::,_ Distance 3: This setting corre-
sponds to a distance of 164 feet/SO meters
when traveling at 62 mph (100 km/h), or a
time interval of 1.8 seconds .

sponds to a distance of 210 feet/64 meters
when traveling at 62 mph (100 km/h), or a
time interval of 2.3 seconds .
A WARNING
Following other vehicles too closely in­
creases the risk of collisions and serious
personal injur y.
- Setting short distances to the traffic
ahead reduces the time and distance
available to bring your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic. -
Always obey applicable traffic laws, use
good judgment, and select a safe follow­
ing d istance for the traff ic, road and
weather conditions .
(D Tips
-Distance 3 is set automatically each time
you switch the ignition on.
- Your standard settings are automatically
stored and assigned to the remote con­
trol key being used.

Fig. 105 Instrument cluste r: request fo r dr ive r inter­
vent ion
In certain situations, the system will prompt
you to take action . This could happen, for ex­
amp le, if braking by the adaptive cruise con­
trol system is not enough to maintain enough
distance to the veh icle ahead .
The indicator light . and the symbol in the
display will warn you about the situation

- Always remember that the radar sensor
for the braking guard works only withi n
defined detection and range limits that
may prevent the proper detection of oth­
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not
be promptly detected or may not be de­
tected at al l.
- Reflective surfaces in cl ud ing crash barr i­

Homelink
Universal remote
control
General information
Applies to vehicles: with Home link unive rsal remote con­
tro l
The Homelink universal remote control can
be programmed with hand -held transmitters
from existing equipment
Using the Homelink universal remote control,
you can operate equ ipment such as garage
doors, property gates and house lights from inside your vehicle .
Using the Homelink universal remote control,
you can replace up to three separate hand ­
held transmitters for equipment on your
property with just one universal remote con­
trol. Most of these transmitters a re used to
operate ga rage doors and property gates. The
individual transmitters are programmed at
the front bumper. That is where the control
module is located.
The transmitters must be programmed first in
order to operate systems using the Homelink
universal remote control.
A WARNING , .,.
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as required by federal safety stand­
ards . Th is 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 . Us ing a garage door
opener without these features increases
risk of serious injury or death.
- 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
H ome link 131
Homelink remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, this can overstrain motor and
damage its electrical components -an
overheated motor is a fire hazard!
- To avoid possible injuries or property
damage, please always make absolutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equipment being ope rated.
(D Tips
- If you would like additional information
on the Home link Universal Transce iver
