Audi adaptive cruise
control and braking
guard
Introduction
App lies to: veh icles with Audi adaptive cruise contro l
The adaptive cruise control system assists the
driver by regulat ing vehicle speed and helping to
maintain a set distance to the vehicle ahead,
within the limits of the system.
If the system de
tects a moving vehicle up ahead, adaptive cruise
control can brake and then accelerate your veh i
cle . This helps to make driving more comfortable
on long highway stretches .
The braking gua rd system can warn you about an
impend ing collision and initiat e braking maneu
vers
¢ page 115.
Adaptive cruise control and braking guard have
technical lim itations that you must know, so
please read th is section carefully, understand
how the system works and use them properly at
all times.
General information
General information
Applies to: vehicles with Audi adaptive cruise control
Fig. 122 Fro nt o f th e ve hicle: Pos it ion of rada r sen sor
The area that contains the radar sensor
¢
fig . 122 must never be covered by st ickers or
other objects or obs tructed with dirt, insects,
snow or ice that w ill interfere w ith the adaptive
cruise control system and braking guard. For in
formation on cleaning, refer to¢
page 204 . The
same applies for any modifications made in the
front area . T
he function of the adaptive cruise control sys
tem and braking guard is limited under some
condit ions:
- Ob jects can on ly be de tected when they are
within sensor range
q page 111, fig . 125.
-The sys tem has a limited ability to de tect ob
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane .
- Some kinds of veh icles are hard to detect; for
examp le motorcycles, ve hicles w ith hig h
ground clearance or overhanging loads may be
detected when it is too late or they may not b e
detected at all.
- When driving through curves

,&_ WARNING
-= -Always pay attention to t raffic when adaptive
cruise control is switched on and braking
g uard is active. As the driver, you are still re
sponsible for starting and for maintain ing
speed and distance to other objects . Braking
g uard is used to ass ist you . The driver must
a lways take act ion to avoid a co llision . The
driver is always respons ible for braking at the
cor rect time.
- I mproper use of adaptive cruise control can
cause collisions, other accidents and ser ious
pe rsonal injury.
- Never let the comfort and conven ience that
adapt ive cr uise control and braking g uard
offe r distract you from the need to be a lert
to traffic cond itions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adapt ive cruise
control and braking guard have limits -they
will not slow the vehicle down or maintain
the set distance when you dr ive towards an
obstacle or something on or near the road
that is not moving, such as vehicles stopped
in a traff ic jam, a stalled or disab led vehicle .
If reg istered by the radar sensor, vehicles or
obstacles that a re not mov ing can trigger a
coll is ion warning and if confi rmed by the
video camera, an acute co llision wa rning.

Offroad dri ving
Offroad driving
Driving under difficult
conditions and off-road
General information
The operation of the Electronic Stabilization Con
trol (ESC) is expanded for operation away from
paved roads. In situations where slip or a differ
ential locking function is required, the offroad mode can be activated
<=> page 186. Your Audi al
so has permanent all-wheel drive in addition .
However, your Audi is not a pure offroad vehicle.
It was not built for driving under extreme condi
tions, e.g. for trips that are in the nature of an
expedition .
Drive only on roads and offroad sections which
match the design of your vehicle and your abili
ties as a driver. Never take risks!
Befo re driving offroad
-Check the eng ine oil level, tire pressure, coo l
ant level, and the fluid leve l in the windshield
washer reservoir.
- Stow luggage items and other objects in the
lu ggage compartment, and secure them
against sliding around.
After driving offroad
-After trips offroad, remove any twigs and other
foreign objects from the grill, the underbody
and the wheels. Pay specia l attention to foreign
objects (stones) which have become lodged in
the tire tread.
- Clean the body and the vehicle underside, and
inspect the vehicle for possible damage.
- Clean dirty windows, headlamp lenses, rear
lights, and license plates.
- Perform a brake check (particularly after travel
ling through water) .
A WARNING
- Drive especially attentive ly and plan ahead
in difficult road conditions and when off
road. Excessive speed or incorrect maneu
vers can cause in juries and damage to the
vehicle.
198
- Always adapt your speed and driving style to
road, offroad, traffic, and weather condi
tions. Drive especially slowly offroad when
your view is restricted.
- Please be aware that in offroad mode, par
ticularly on a smooth and slippery road, the
wheels may have an increased tendency to
spin and the vehicle may break away - dan
ger of skidding!
- Stability is limited in the offroad mode.
® For the sake of the environment
Avoid damage to the environment and re
spect nature.
(D Tips
Only drive where it is permitted and stay on
marked roads and paths.
Explanation of some technical terms
The following data refer to ideal conditions. De pending on vehicle load and ground conditions
and the env ironment, the numbers may vary. It is
the driver's responsibility to decide whether ave
hicle can overcome a specific s ituation
<=> .&. .
Gradient angle
The number of meters in alt itude gained over a
distance of 109.4 yards or 100 meters (grade)
are given as a percentage or degrees . Informa
tion about the gradient the vehicle can cl imb un
der its own power (depends in part on the road
surface and eng ine power). Maximum permitted
grade: 31
°
Ground clearance
The distance between the road surface and the lowest point of the vehicle underbody. Ground
clearance 7.9 in (200 mm)
.&, WARNING
Exceeding the stated maximum figures can
result in severe injuries or vehicle damage.

Driving tips
On poor rood and offrood, there is always only
one motto: Plan ahead and drive slowly!
Please observe the following when driving away
from paved roads:
~ Drive only on roads and offroad sections wh ich
match the design of your veh icle and your abili
ties as a driver. Never take risks!
~ Drive slowly and plan ahead!
~ Take into consideration the ground clearance
of your veh icle.
~ Activate the off road mode q page 186 as need
ed .
~ Use the hill descent assist q page 188 when
driv ing down steep sections on h ills.
Unpaved road s and offroad
Drive s low ly on unfamiliar roads and unknown
offroad sections, and look out for unexpected ob
stacles (e .g . potholes, rocks, tree stumps, etc .).
T o prevent the vehicle from bottoming and avoid
damage to the underbody, you should drive
stra ight across severe bumps in the ground with
only one side of the vehicle so that only two of
your wheels cross the bumps .
Drive briskly through sandy or marshy offroad
sections and do not stop, if at all possible.
Driving through water
Note the following to avoid vehicle damage when
driving through water, for example on flooded
roads:
- Th e wate r must not be any higher than the bot-
tom of the vehicle body.
- Do not drive faster than walking speed.
Driving on a slope
If you ever find yourself not able to climb a slope,
do not try to turn around, drive back down in
re
verse.
Othe rw ise, you run the risk of tipping over.
Offroad driving
If the vehicle threatens to tip over when driving
across a slope, you must immediately steer
downhill in the direction of the slope.
Do not park your vehi cle on steep slopes or
grades .
T o reduce the risk of tipping over, drive on slopes
i n the direction of the downward slope (fall line) -
not crosswise .
& WARNING ~ -
After driving thro ugh water, mud, slush, etc.,
the brakes may be slow to take effect beca use
of wet brake rotors and pads. Dry the brakes
f ir st by braking carefu lly to restore the full
braking effect.
(D Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys
tem can be severely damaged by driving
through water .
- Always switch off the Start-Stop-System*
when driving through water
Q page 90.
(D Tips
-Check the depth of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
-Avoid dr iv ing through salt water because it
can cause corros ion.
