Audi adaptive cruise control and braking guard
Audi adaptive cruise
control and braking
guard
Introduction
Applies to vehicles: with Audi adaptive cruise contro l
The adaptive cruise contro l system assists the
driver by regulating vehicle speed and helping to
maintain a set distance to the veh icle 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 vehi
cle. This helps to make driving more comfortable
on long highway stretches.
The braking guard system can warn you about an
impending collision and initiate braking maneu
vers

Adaptive cruise control and braking guard have
technical limitations that you must know, so
please read th is section carefully, understand
how the system works and use them properly at
all times.

The function of the adaptive cruise control sys
tem and braking guard is limited under some
condit ions:
- Objects can only be detected when they are
within sensor range
<:!) page 108, fig . 119.
-The system has a limited ability to detect ob
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane.
- Some k inds of veh icles are hard to detect; for
example motorcycles, veh icles 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 i::!) page 107.
& WARNING
-Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re
sponsible for starting and for maintaining
speed and distance to other objects . Braking
guard is used to assist you . The driver must
a lways take action to avoid a collision . The
driver is always responsible fo r braking at the
correct time.
- Improper use of adaptive cruise contro l can
cause collisions, other accidents and serious
personal injury.
- Never let the comfort and convenience that
adapt ive cr uise control and braking guard
offe r dist ract you from the need to be alert
to traffic cond itions and the need to remain
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 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 veh icle.
If registered by the radar sensor, veh icles o r
obstacles that are not moving can trigger a
coll ision warning and if confirmed by the
video camera, an acute collision warning. ..,

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 fun ction is required , the offroad
mode can be activated ¢
page 190. 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 tr ips 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!
Before driving offroad
-Check the engine oi l level, tire pressure, coo l
ant level, and the fluid level in the windshield
washer reservo ir.
- Stow luggage items and other objects in the
luggage compartment, and secure them
against sliding around.
After driving offroad
-After trips offroad, remove any twigs and other
foreign objects from the gri ll, the underbody
and the wheels. Pay special 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 attentively and plan ahead
in difficult road condit ions and when off
road. Excessive speed or incorrect maneu
vers can cause injuries and damage to the
vehicle .
Offroad driving
-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 skidd ing!
- Stability is lim ited 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 environment, 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 altitude gained over a
distance of 109.4 yards or 100 meters (grade)
are given as a percentage or degrees. Informa
t ion about the gradient the vehicle can cl imb un
der its own power (depends in part on the road
s ur face 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.
- All the information was gathered on level,
