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. 114 Front of the vehicle: Position of radar sensor
The area that contains the radar sensor
c::;, fig. 114 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 219. 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. 117.
-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

-Stationary objects c::;, page 108.
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 con trol
can cause collisions, other accidents and
serious personal injury .
- Never let the comfort and convenience
that adaptive 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 .,.
210 Driving off road
Breakover angle
Indicates the angle up to which the veh icle
can drive over a ramp at low speed without
the underside of the vehicle hitting the edge
of the ramp. Maximum permitted breakover
angle: 17°
Approach/departure angle
Transition from the horizontal pla ne to a g ra
dient or from a grade back to level ground. In
dicates the angle up to which the vehicle can
drive onto or off a slope at low speed without
striking 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 of the vehicle underbody.
Ground clearance 7.9 in (200 mm)
A WARNING
Exceeding the stated maximum figures
-
can result in severe injuries or vehicle dam
age.
- All the information was gathered on lev
el, firm and non-slippery road surfaces,
and under dry weather conditions.
- Ideal conditions do not prevail offroad.
Never utilize the maximum readings to
their fullest, always leave a safety re serve.
Driving tips
On poor road and offroad, there is always on
ly one motto: Plan ahead and drive slowly!
Please observe the following when dr iving
away from paved roads:
• Drive only on roads and offroad sections
wh ich match the design of your vehicle and
your abilities as a dr iver. Never take risks!
• Drive slowly and plan ahead!
• Take into consideration the
ground clear
ance
of your vehicle.
• Activate the
ESC off road mode ~ page 19 7
as needed. •
Use the
hill descent assist¢ page 199
when driving down steep sections on hi lls .
Unpaved roads and offroad
Drive slowly on unfamiliar roads and unknown
offroad sections, and look o ut for unexpected
obstacles (e.g . potholes, ro cks, tree stumps,
etc.).
To prevent the vehicle from bottoming and
avo id damage to the underbody, you should
drive straig ht across severe bumps in the
ground with only one side o f the ve hicle so
that only two of yo ur whee ls cross the bumps.
Drive briskly through sandy or marshy offroad
sections and do not stop , if at all possible.
Driving through water
Note the follow ing to avoid veh icle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than walk ing speed .
Driving on a slope
If you ever find yourse lf not able to climb a
s lope, do not try to turn around, drive back
down in
reverse. Otherwise, you run the r isk
of tipp ing over.
If the vehicle threatens to tip over when
driving across a slope, you must immediate
ly steer downhill in the direction of the
slope.
Do not park your vehicle on steep s lopes or
grades.
T o red uce the risk of tipping over, drive on
s lopes in the direction of the downward slope
(fall line) -
not crosswise.
A WARNING
-~
After driving through water, mud, slush,
etc ., the brakes may be s low to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re-
store the full braking effect. .,..
