There must be at least 10 inc hes (25 cm) be­
tween you r chest and the center of the steer ­
ing whee l.
If you cannot sit more than 10 in­
ches (25 cm) from the steering whee l, see if
adaptive equipment is available to help you reach the pedals and increase the distance
from the steer ing wheel.
F or detai led information on how to adjust the
driver's seat, see
<::> page 54 .
In vehicles with the memory f unction* , the
steering column settings are stored together
with the seat position.
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause se rious personal injury.
- Adjust the steer ing whee l column on ly
when the vehicle is not moving to pre­
vent loss of veh icle control.
-
- Adjust the driver's seat or steering wheel
so that the re is a min imum of 10 inches
(25 cm) between your chest and the
steering wheel ¢
page 1211 fig. 146. If
you can not maintain this min imum dis­
tan ce, the airbag system cannot protect
yo u properly.
- If phys ica l limi tations prevent you from
sitting 10 in ches (25 cm) o r more from
the steering wheel, check with yo ur au­
tho rized Aud i dealer to see if adaptive
equipment is availab le .
- If the steering wheel is aligned with you r
face, the supp lemental drive r's airbag
cannot provide as much protect ion in an
acc ident. A lways make sure that the
steering wheel is aligned with your
chest.
- Always hold the steering wheel with your
hands at the 9 o'clock and 3 o'clock posi­
t ions to reduce the risk of pe rsonal injury
if the d river 's airbag deploys.
- Never hold the steering whee l at the 12
o'clock posit ion or w ith your hands i nside the steering wheel rim or on the steering
wheel hub. Hold
ing the steer ing wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er 's airbag deploys.

_& WARNING ,_
Emergency braking should only be used in
an emergency, when the norma l foot bra ke
has fa iled or the brake pedal is obstructed.
Using the parki ng brake to perform eme r­
gency b raking will s low your veh icle down
as if you had made a full bra ke application .
The law s of physi cs cannot be su spen ded
even wi th ESC and i ts asso ciated com po­
nents (ABS, A SR, EDL) . In corners and
when road o r weathe r con ditions are bad,
a full brake application can ca use the vehi­
cle to sk id or the rear end to break away -
risking an accident.

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. 88 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. 88
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 201. 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. 91 .
-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 .

stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).
- Always remember that the radar sensor
for the braking guard works only within
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 all.
- Reflective surfaces including crash barri­
ers or tunnel entrances may impair the
function of the radar sensor.
({) Tips
-You can cancel the braking with increas­
ing force that is initiated by the system
by braking yourself, by accelerating no­
ticeably or by swerving.
