-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 tempera­
ture rises as the result of heat buildup or
if the engine compartment is heated by
the sun's rays and the engine is hot.
(D 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 sw itched off -there is a ris k of
damaging the engine. For this reason, let
the engine run for at idle for approx imate ­
ly two minutes before shutting it off.

86 Audi adapti ve cruise control
Audi adaptive cruise
control
Introduction
Applies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system is a combi­
nation of speed and distance regulation. It as­
sists the driver by both regulat ing the speed
and maintaining a distance to the object
ahead, within the abilit ies of the system. If
the system detects an object, adaptive cru ise
con trol can brake and acce le rate your veh icle.
This makes driving more comfortable both on
long stretches of highway and in stop-and -go
traffic.
General Information
General information
Applies to vehicles: with Audi adaptive cruise control and
Audi pre se nse front
Fi g. 75 Front of veh icle: sensor
The genera l information applies to adaptive
cruise control * and pre sense front *
c:;, page 94.
The radar sensor a rea c::> fig. 75 m ust not be
covered w ith stickers, deposits or a ny other
obstructions as it may impair the function of
the adaptive cruise control and the pre sense
front. For information on cleaning, refer to
c:;, page 205. The same applies for any modifi­
cations made in the front area.
The function of the adaptive cruise control
system and pre sense front is limited in some
conditions : -
Objects can on ly be detected when they are
within the sensor range
c::> page 87,
fig. 78.
-The system has a limited ability to detect
objects that are a short distance ahead, off
to the side of your vehicle or moving into
your lane.
- Objects that are difficult to detect such as
motorcycles, vehicles with high ground
clearance or an overhanging load are detect­
ed late or not detected at all.
- When driving through curves
c::>page 87.
-With stationary objects c::> page 87.
A WARNING
-
Always pay attent ion to traffic when adap­
tive cruise control is switched on and the
pre sense front is active
c::> page 94. As
the driver, yo u are still responsible for
start ing and for mainta ining speed and
d istance to other objects. The pre sense
front is used to ass ist you. The dr iver must
a lways take action to avo id a collision . The
driver is always responsible for braking at
the correct time.
- I ncorrect use of the adaptive cruise con­
trol can cause collisions, other accidents
and serio us personal injury.
- For safety reasons, do not use adaptive cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplaning). Us ing the system unde r
these conditions could result in a coll i­
sion .
- Switch adaptive cruise control off tempo­ rarily when driving in tu rni ng lanes, o n
expressway ex its or in construction
zones. This prevents the vehicle from ac­
celerating to the set speed when in these
situations .
- The adaptive c ruise control system will
not brake by itself if you put your foot on
the accelerator pedal. Doing so can over-
ride the speed and distance reg ulation . ..,_

using the multifunction steering wheel b ut­
tons ¢
page 28 .
Based on the g raphics in the display, yo u can
determ ine if the system is maintaining a dis ­
tance to a vehicle ahead and what that dis­
tance to this vehicle is:
N o vehicle -No object ahead was detected .

Both arrows on the scale© in dicate the dis ­
tance to the object ahead. No arrow appears
when the vehicle is on an open road and there
is no object ahead.
If an object is detected
ahead, the arrow moves on the scale.
The green zone on the scale indicates the

the distance, refer to r::!> page 91. If the dis ­
tance selected is exceeded or not reached, the
arrow moves into the red zone on the scale.
_& WARNING
- Using adaptive cru ise contro l incorrectly
can cause collisions, other acc idents and
ser ious inju ries .
- If you press t he
~IS-E T ~I button when driv­
ing at speeds below 20 mph (30 km/h),
the vehicle acce lerates automatically up
to 20 mph (30 km/h), wh ich is the mini­
m um speed that can be set.
(D Tips
- If you switch the ig nit ion or the adaptive
cruise cont ro l system off, the set speed
is e rased for safety reason .
- The Elect ronic Stabilization Control (ESC)
and Anti-Slip Regulat ion (ASR) both
switch on when the adaptiv e cruis e con­

Driving in stop-and-go traffic
Applies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system assists you
in stop-and-go traffic. If an object that is de­
tected ahead stops, your vehicle will brake
and stay at a stop, within the limits of the sys­
tem.
