Audi adaptive cruise
control
Description
App lies to : vehicles wi th Audi adap tive c ru ise con trol
Fi g. 89 Detect io n range
The adaptive cru ise cont rol system is a comb ina­
tion of speed and dis tance regu lation.
It ass ists
t h e d river by bo th regu lating the speed and
maintain ing a d is ta nce to the vehicle driv ing
ahead, within the limits of the system. If the sys ­
tem detects a vehicle d riving ahead, the adaptive
cruise contro l can brake and accelerate yo ur vehi­
cle. T his makes driving more comfo rtable both
o n long st retches of hig hway and in stop-and-go
traffic .
What can adaptive cruise control do?
The adaptive cru ise control system uses video, ra­
dar, ultrasound and navigat ion data . Vehicles
driv ing ahead can be recognized up to 650 feet
(200 m) away .
Pred ictive functions offer the drive r additional
comfort and contr ibute to the reduct ion in fuel
consumption a nd CO2 em issions
r::::> page 102.
On open roads with no traffic, it functions like a
cruise contro l system. The stored speed is main ­
ta ined . When approaching a vehicle d riving
ahead, the adaptive cruise contro l system auto­
matically brakes to match that vehicle's speed
and then maintains the set dis tance. As soon as
the system do es not detect a vehicle dr iv ing
ahea d, adaptive cruise cont rol accelerates up to
t h e s to red spee d.
In stop-a nd-go traffic, adap tive cruise control can
brake until the veh icle is sta tionary a nd then can .,.

General information
The predict ive control 1> uses the map informa­
tion from the navigation system in order to react
proactively when driving. Information from the
camera -based traffic sign recognition* is also ap­
plied to recognize traffic signs
c::> page 24. When
coming up to areas with speed limits or changes
in the course of the road (such as curves, inter­
sections or traffic c ircles), the system brakes au­
tomatically and then accelerates back up to the
set speed .
When adaptive cruise control is switched off, the
system only provides notifications without con­
trolled interventions
c::> page 95.
The driver can override the predictive contro l at
any time by pressing the accelerator or brake
pedal. If the system changes the veh icle speed to
adapt to speed limits, you can change the speed
using the lever
c::>page 99 , fig . 95.
Always switch off the predictive control in
the following situations:
-When increased attention is needed from the
driver .
- In poor weather conditions such as snow or
heavy rain .
- When driving on roads in poor cond ition.

Safety belts
_& WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death . Safety belts can work only
when used correctly.
-Always fasten your safety belts correctly be­ fore driving off and make sure all passen­
gers are correctly restrained.
- For maximum protection, safety belts must
always be positioned properly on the body.
- Never strap more than one person, includ­
ing small children, into any belt.
- Never place a safety belt over a child sitting
on your lap.
- Always keep feet in the footwell in front of
the seat while the vehicle is being driven.
- Never let any person ride with their feet on
the instrument panel or sticking out the
window or on the seat.
- Never
remove a safety belt while the vehicle
is moving . Doing so will increase your risk of
being injured or killed .
- Never wear belts twisted.
- Never wear belts
over rigid or breakable ob-
jects in or on your clothing, such as eye
glasses, pens, keys, etc., as these may cause
injury.
- Never allow safety belts to become dam­
aged by being caught in door or seat hard­
ware .
- Do not wear the shoulder part of the belt
under your arm or otherwise out of position.
- Several layers of heavy clothing may inter­
fere with correct positioning of belts and re­
duce the overall effectiveness of the system.
- Always keep belt buckles free of anything
that may prevent the buckle from latching
securely .
- Never use comfort clips or devices that cre­
ate slack in the shoulder belt. However, spe­
cial clips may be required for the proper use
of some child restraint systems.
- Torn or frayed safety belts can tear, and
damaged belt hardware can break in an acci­
dent . Inspect belts regularly.
If webbing,
bindings, buckles, or retractors are dam-
248
aged, have belts replaced by an authorized
Audi dealer or qualified workshop.
- Safety belts that have been worn and loaded
in an accident must be replaced with the
correct replacement safety belt by an au­
thorized Audi dealer. Replacement may be
necessary
even if damage cannot be clearly
seen . Anchorages that were loaded must al­
so be inspected.
- Never

one o f the rear seating posit ions . If in exception ­
al circumstances you must use it on the front passenger seat, carefully read all of the informa­
tion on child safety and Advanced Airbags and heed a ll of the app licab le WARNINGS. Make cer­
tain that the child and child restraint are correct­ ly recogn ized by the capacit ive passenger detec­
tion system i n the front passenge r seat, that the
fron t passenger airbag is turned off, and that the
a irbag status is always cor rectly sig naled by the

M any types and models of child rest raints have
been available ove r the yea rs , new models are in­
troduced regularly incorporat ing new and im­
p roved designs and older mode ls are taken o ut of
product ion . Chi ld restraints a re not standardized .
Ch ild rest raints of the same type typica lly have
d ifferent weights and s izes and d ifferent "foot­
prints", the s ize and shape of the bottom of the
chi ld restraint that s its on the seat, when they
are installed on a vehicle seat . These differences
make it virtually impossible to ce rtify compliance

The convertible locking retractor for child re­
straints will be deactivated automatically when
the belt is wound all the way back into the re­
tractor .
~ Press the red button on the safety belt buckle.
The belt tongue will pop out of the buckle.
~ Guide the safety belt all the way back into its
stowed position .
Always let the safety belt retract completely into
its stowed position. The safety belt can now be
used as an ordinary safety belt without the con­
vertible locking retractor for child restraints.
If the convertible locking retractor should be ac­
tivated inadvertently, the safety belt must be un­
fastened and guided completely back into its
stowed position to deact ivate this feature. If the
convert ible locking retractor is not deactivated,
the safety belt w ill gradually become tighter and
uncomfortable to wear.

LATCH system (Lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicab le way to
attach the child restraint on the vehicle seat,
Federal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LATCH system for
"Lower Anchorages and Tethers for Children". In
Canada, the terms "top tether" with "lower uni­
versa l anchorages" (or "lower universal anchor­
age bars") are used to descr ibe the system .
In other countries the term "ISOFIX" is used to
describe the lower anchorages .
Forward-facing child restraints manufactured af­
ter September 1, 1999, are required by U.S. fed­
eral regulations to comply with new child head
movement performance req uirements. These
new performance requirements make a tether
necessary on most new ch ild seats.
Installing a child restraint that requires a top
tethe r without one can seriously impair the per­
formance of the child restraint and its ab ility to
pro tect the child in a collision. Installing a child
restra int that requi res a top tether without the
top tether may be a violation of state law.
Child restraint manufacturers offer LATCH lower
anchorages on their child seats w ith hook-on or ..,.

Wheels
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8-pillar, always follow the specifica­
tion on the 8-pillar label
¢ page 327, fig. 255.

(i} For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the

lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 329
or for a full load
when the vehicle is partially loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.

Low aspect ratio tires
Your Aud i is facto ry-equipped with low aspect ra ­
tio ti res. These t ires have been tho rough ly tested
and been se lected specifically for yo ur model for
their superb per formance, road feel and handling
under a variety of driving conditions. Ask your au­
thorized Audi dealer for more details .
The low aspect ratio of these t ires is indica ted by
a numera l of
55 or les s in the tire's size designa ­
tion. The numeral represents the ratio of the
tire's sidewall height in r elation to its tread width
expressed in percentage. Conventional tires have
a height/w idth rat io of 60 or more.
The performan ce of low-aspect- ratio tire s is par­
ticularl y sensiti ve to improper inf lat ion pres­
sure . It is therefore impo rtant that low aspect
ratio tir e s are infl ated to the specified pressu re
and tha t the inflation pr essure is regularly
checked and maint ained . Tire pre ssure s should
be check ed at lea st once a month and alwa ys
b efore a long trip<=:>
page 32 7.
What you can do to a void tire and rim
damage
L ow aspect rat io tires can be damaged more easi­
l y by impact with potho les, cu rbs, gull ies or
r idges on the road, pa rtic ularly if the tire is un­
derinflated.
Wh eel s
In order to min imize the occurrence o f impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau ­
t ions:
- Always maintain recommended inflation pres ­
sures . Check your tire pressure every 2,000
m iles (3,000 km) and add air if necessary .
- Drive carefully on roads with potholes, deep
gu llies or ridges . The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immed iate ly inspect your
tires or have them inspected by the nearest au­
thorized Audi dealer . Replace a damaged tire as
soon as possible .
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not always
easy to see . Damage can lead to loss of a ir and
underinflation, wh ich could eventually cause
tire fa ilu re . If yo u bel ieve that a tire may have
been damaged, replace the tire as soon as pos­
sible.
= These tires may wear mo re quickly tha n others.
- Please also remember that , while these tires
de live r responsive ha nd ling, they may ride less
comfort ably and make more noise t han other
choices .
Reduced performance in w inter /cold season
conditions
All tires are des igned for certai n pu rposes. The
low aspect ratio, ultra high performance tires
origina lly installed on your vehicle are intended
for maximum dry and wet road performance and handling. They are not suitable for co ld, snowy or
icy weather conditions. If you drive under those
c ircumstances, you should equip your vehicle
with all -season or winter tires, which offer better
tract ion under those conditions . We suggest you
use the recommended s now or a ll-season tires
spe cified for your vehicle, o r their equiva lent.
