Audi adaptive cruise control and braking guard 107
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 on long highway
stretches.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers

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. 113 Front of the vehicle: Position of radar sensor
The area that contains the radar sensor
c::;, fig. 113 must never be covered by stickers
or other objects or obstructed with dirt, in
sects, snow or ice that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
c::;, page 217. The same applies for any modifi
cations made in the front area . The
function of the adaptive cruise control
system and braking guard is limited under
some cond itions:
- Objects can only be detected when they are
within sensor range
.:!>page 109 , fig. 116.
-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.
- Some kinds of vehicles 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

A WARNING
-Always pay attention to traffic when adap-
tive cruise control is switched on and brak ing guard is active. As the dr iver, you are
still respons ible for start ing and for main
tain ing speed and distance to other ob
jects. Braking guard is used to assist you.
The driver must always take action to avoid
a collision. The driver is always responsible
for braking at the correct time.
- Improper use of adaptive cruise control
can caus e collisions, other accidents and
serious personal inj ury .
- Never let the comfort and convenience
that adap tive cruise control and braking
guard offer d istract you from the need to
be alert to traffic conditions and the
need to remain in fullcontrolofyourve
hicle at all times,
- Always remember that the adaptive
cru ise contro l and braking guard have
limits -they will not slow 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
moving, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle.
If registered by the radar sensor, vehicles
or obstacles that are not moving can
trigger a collision warning and if .,.
Breakover angle
Indic ates t he angle up to whi ch the veh icle
can drive ove r a ramp at low speed w it h out
the unde rside of the veh icle hitting the e dge
of t he ramp. Maximum permitted breakover
angle: 17°
Approach /departure angle
Transi tion from the ho rizon tal p lane to a g ra
d ient or from a grade back to level gro und. In
d icates the angle up to which the vehicle can
drive onto or off a s lope at low speed without
stri king the bumper or the underbody. Maxi
mum permitted approach/departure angle :
25° (front), 20° (rear)
Ground clearance
The distance between the road surface and
the lowest point o f the veh icle unde rbody.
Ground clearance 7.9 in (200 mm)
A WARNING
Exceeding the stated maximum figures
-
can result in severe injuries or veh icle dam
age.
- All the information was gathered on lev
el, firm and non-slip pery road surfaces,
and unde r dry wea ther condi tions .
- Ideal conditions do not prevail offroad .
Never utilize the maximum rea dings to

... Use the hill descent assist~ page 199 when
driving dow n steep sections on hills.
Unpaved roads and offroad
Drive slowly on unfamiliar roads and unknown
off ro ad sec tions, an d loo k out for unexpec ted
o bstacles (e.g . potholes, roc ks, tree s tumps,
etc.).
T o p reven t the vehicle from bo ttoming and
av oid da m age to t he underbody, yo u should
d rive s traig ht a cross severe bumps in the
gro und with only one side o f th e veh icle so
that only two of yo ur whee ls cross the bumps .
Drive br is kl y through sandy o r m arshy offro ad
sections and do not stop, if at all possible.
Driving through water
Note t he follow ing to avoid veh icle damage
whe n driving through water, for examp le on
f loo ded roa ds:
- The water must not be any higher t han the
