There is a system malfunction that can result
in restr icted driving stability or reduced
ground clearance .
Drive to your authorized Audi dea ler immedi
ately to have the malfunction corrected.
II Air suspension: vehicle too low. Ground
clearance reduced
The ground clearance is ve ry low due to a sys
tem malfunction . Wait until the air suspen
sion system has restored normal ground clear
ance . Otherwise, conditions such as an uneven
road surface can lead to vehicle damage.
tfsl !f Safety systems
The fl (USA models) ;fll (Canada models) in
d icator light monitors the safety systems (e.g.
a ir bags, pretensioners) and illuminates for a
few seconds each time you switch the ignition
on.
If the
fl (USA models)I E,I (Canada models)
indicator light does not go out, or if it illumi
nates while you are driv ing, or if it starts to
blink, then there is a malfunction somewhere in
the system. If the light does not illuminate
when you switch the ignition on, this also
means there is a malfunct ion .

tems, contact your authorized Audi dea ler
im mediately . Otherwise the safety sys
tems may not work properly in an acc i
dent.
Lt Central indicator light
If the indicato r light . or II turns on, check
the message in the instr ument cluster.
f;,J [); Electronic Stabilization Control
(ESC)
If the lj] indicator light blinks while driving,
the ESC or ASR (Anti-Slip Regulation) is active

has switched the ESC off. In this case, you can
switch the ign ition off and then on to switch
the ESC on aga in. The ind icator light turns off
whe n the system is functioning fully.
If the

owner's manual
If the J.j] indicator light and the ABS indicator
light
fJln (USA mode ls) ,1IJ (Canada models)
turn on and the message appears, the ABS or electronic differentia l lock is malfunctioning.
This also causes the ESC to malfunction. The
brakes still function with their normal power,
but ABS is not active .

Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system assists the
driver by regu lating vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system . If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac
celerate your vehicle. Th is he lps to make driv
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers¢
page 87.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un
derstand how the system works and use them
properly at all times.
General information
General information
Applies to vehicles: with Audi adaptive cruise control
Fig. 86 Front of the vehicle: sensors and video came ra
The areas that contain the radar and ultrason
ic sensors and the v ideo camera ¢
fig. 86
must neve r be covered by stickers or other ob
jects or obstructed with dirt, insects, snow or
ice that will interfere with the adaptive cruise
control system and braking guard. For infor
mation on cleaning, refer to¢
page 203. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some conditions:
- Objects can on ly be detected when they are
w ith in sensor range
¢page 83, fig. 89 .
-The system has a limited ability to detect
objects that are a shor t distance ahead,
off
t o the side of your vehicle or moving into
your lane.
- Some kinds of ve hicles are hard to detect;
for examp le motorcycles, vehicles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at all.
- When driving through curves
¢page 82 .
- Stationary objects¢ page 82.
& WARNING
Always pay attent ion to traffic when adap
tive cruise control is switched on and brak ing g uard is active. As the driver, you are
still respons ible for starting and for ma in
taining speed and distance to other ob
jects . Braking guard is used to assist you .
The driver must always take action to avo id
a collision. The driver is always responsible
for braking at the co rrect time.
- Improper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and conven ience
that adaptive cruise control and braking
guard offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in full control of your ve
hicle at all times,
- Always remember that the adaptive
cruise control and braking guard have
limits -they will not s low the vehicle
down or maintain the set distance when
you drive towards an obstacle or some
thing on or near the road that is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle .
