Audi adaptive cruise control and braking guard 99
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 113 Instrument cluste r: approac h warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise control is switched off.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own vehicle is traveling at a high speed and approaching a vehicle up
ahead that is moving more slowly . Braking
gua rd does not react if it cannot detect the
situation .
The system advises you of various situations:
- The distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you wi ll
not be able to avoid a collis ion. The indicator
light. in the display comes on .
- The approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing much more slowly than you are or if it
brakes sharply . When th is warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. Th e indicator
light. and indicator in the display will
warn you about the danger
c::> fig. 113. You
will a lso hear an acoustic signa l.
If you do not react fast enough or do not react
at all to the situation, Braking guard will in-

tervene by braking and the message braking
guard intervention will appear.
- If a coll ision is imminent , the system will
first provide an acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake within the lim its of
the system. This reduces the vehicle speed
in the event of a collision.
- At speeds unde r 20 mph (30 km/h), the sys­
tem can initiate a comp lete deceleration
shortly before a collision
ll.
- If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the braking force .
Which functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or M MI
c::> page 100, Settings in the radio/
MMI.
A WARNING
-Lack of attention can cause collisions, oth-
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The dr iver is
always respons ible for braking at the cor­
r ect time .
- Always pay close attention to traffic,
even when the braking guard is switched
on . Be ready to intervene and be ready to
take comp lete control whenever necessa­
ry. Always keep the safe and legal dis­
tance between your vehicle and vehicles up ahead.
- Braking guard works within limits and
will not respond outside the system lim­
its, for examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).

R ear vie w camera co verag e ar ea
The MM I d isplay shows the area covered by
the rear view camera ¢
fig. 123 (D. Objects
that are not in the area covered @are not
shown on the MMI display.
We recommend that you p ractice park ing with
the rear view camera in a traffic -free location
or parking lot to become familiar with the sys ­
tem, the orientation lines, and their function.
When doing th is, there shou ld be good light
and weather conditions.
In the MMI disp lay, objects or vehicles appear
closer or further away if:
- you are d riving in reverse gear from a level
surface onto an incline, or a downward
s lope,
- you are driving in reverse gear toward pro ­
truding objects,
- the vehicle is carrying too much load in the
rear .
The accu racy of the orienta tion lines and b lue
surfaces dimin ishes if:
- the rear view camera does not provide a rel i­
able image, for examp le, in poor visibility
condit ions or if the lens is dirty,
- the image on the screen is not visible due to
sun glare and reflect ion.
Cari ng for the rear view came ra len s
The rear view camera is located above the rear
license plate bracket . For the parking assist to
operate, the lens¢
fig. 124 must be kept
clean:
- Dampen the lens with a househo ld alcohol­
based glass cleaner, and clean the lens with
a dry cloth ¢(D .
- Remove snow with a hand brush and ice
preferably with a de -icing spray ¢(D .
A WARNING
-The parking aid cannot replace the driv­
er's attent ion. The dr iver alone is respon­
sible for parking and s imilar driving ma­
neuvers.
-Always keep your eyes on the vehicle 's
sur roundings, us ing the rea r view m irror
as we ll.
- Do not allow yourself to be distracted
from traffic by the rea r view came ra p ic­
tures.
- If the position and t he installation angle
of the camera has c hanged, for e xample,
after a rear end co llision, do not conti nue
to use the system for safety reasons .

Universal remote
control
Description
Applies to vehicles: with Home link
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
With Home Link, you can control devices such
as the garage door, security systems, house
lights , etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to rep lace
three different remote controls from dev ices
in your home with one universal remote. Th is
feature works for most garage door and exte­
rior door motor signals. Programming the in­
dividual remote control for your remote con ­
trol takes place near the center of the radiator
grille. There is a control module attached at
this location .
A one-time programming of the sensor must be performed before you are able to use sys­
tems with Homelink. If the system does not activate after performing the one-time pro­
gramming, check whether the system uses a rolling code¢

What impairs driving safety?
Safe driving is directly related to the condi­
tion of the vehicle, the driver as well as the
driver 's ability to concentrate on the rood
without being distracted.
The driver is responsible for the safety of the
vehicle and all of its occupants. If your ability
to drive is impaired, safety risks for everybody
in the vehicle increase and you also become a
hazard to everyone else on the road ¢
.&,.
Therefore:
• Do not let yourself be distracted by passen­
gers or by using a cellular telephone.
• NEVER drive when your dr iving ability is im­
paired (by medicat ions, alcohol, drugs, etc.) .
• Observe all traffic laws, rules of the road
and speed limits and plain common sense.
• ALWAYS adjust your speed to road, traffic
and weather conditions.
• Take frequent breaks on long trips . Do not
drive for more than two hours at a stretch .
• Do NOT drive when you are tired , under
pressure or when you are stressed.
A WARNING , .
Impaired driving safety increases the risk
of serious personal injury and death when­
ever a vehicle is being used.
Proper occupant
seating positions
Proper seating position for the driver
The proper driver seating position is impor­
tant for safe, relaxed driving.
Fig. 132 Correc t seat ing posit ion
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the driver's seat to the
following position:
• Adjust the driver's seat so that you can easi­
ly push the pedals all the way to the floor
while keeping your knee(s) slightly bent
¢.&, .
• Adjust the angle of the seatback so that it is
in an upr ight position so that your back
comes in full contact with it when you drive.
• Adj ust the steering wheel so that there is a
distance of at least 10 inches (25 cm) be­
tween the steering wheel and your breast
bone ¢
fig. 132. If not possible, see your au­
thorized Audi dealer about adaptive equip­ ment.
• Adjust the steering wheel so that the steer­
ing wheel and airbag cover points at your
chest and not at your face .
• Grasp the top of the steer ing wheel with
your elbow(s) slightly bent.
• Applies to veh icles w ith adjustable head re­
straints: Adjust the head restraint so the up­
per edge is as even as possible with the top
of your head.
If that is not possible, try to
adjust the head restraint so that it is as
close to this posit ion as possible.
• Fasten and wear safety belts correctly

-Safety belts offer opt imum protection
only when the seat back is u pright and
be lts are proper ly posit ioned o n the
body.
-
- Never attach t he safety belt to the buck­
le for another seat. Attaching the belt to
the wrong buckle will reduce safety be lt
effectiveness and can cause serious per ­
sonal injury .
- A passenger who is not proper ly restrain-
ed can be seriously injured by the safety ..,.

For this reason, and because the back seat is
the safest place for children - when properly restrained according to their age and size - we
strongly recommend that children always sit in the back seat
Q page 161, Child Safety.
A WARNING
-
A child in a rearward-facing child safety seat installed on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inflates - even with an Ad­
vanced Airbag System.
- T he inflating a irbag w ill hit the child
safety seat or infant carrier w ith great
force and w ill smash the ch ild safety sea t
and child against the backrest, cente r
armrest, door or roof .
- Always install rear -facing child safety
seats on the rear seat.
- If you mus t inst all a rearward facing
child safety seat on the front passenger
seat beca use of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on , im­
med iately install the rear-facing child
safety seat in a rear seating posit ion and
have the a irbag system inspected by your
authorized Aud i dealer .
- Forward-fac ing ch ild safety seats instal­
led on the front passenger's seat may in­
terfe re with the deployment of the air­
bag and cause se rious personal injury to
the ch ild.
A WARNING
If, in exceptional c irc umstances, you mus t
install a forwa rd-facing child restra int on
the front passenger's seat:
- Alw ays make sure the forw ard -fac ing
sea t has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward -facing child re ­
straint up aga inst or very near the instru­
ment pane l.
- Always move the passenger seat into its
rearmost position in the seat's fore and

146 Airbag sys te m
For exa mpl e, the air b ag ma y depl oy if:
- a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whe ther the child is in one of
the chi ld safety seats listed
¢ page 163),
-a ch ild who has outgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PA SSENGER AIR BAG OFF light in the cente r
of the instrument panel w ill come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PAS SENGER AIR BAG OFF
light does not illuminate and stay lit) if:
- a small adult or teenager is on the front pas­
senger seat
- a passenger who is not sitt ing upright wit h
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the seat is on the front passenger seat.
If the front passenger airbag deploys, the Federal Standard requires the airbag to meet
the "low risk" deployment criteria to help re­
d uce the risk of inju ry through interaction
with the airbag. " Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the e lectronic control
un it.
¢ page 150
Alw ays re memb er: Even tho ugh you r vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat . Please be sure to read the impor­
tant information in the sect ions that follow
and be sure to heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag
inf lates, always wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of in jury is much higher.
- You w ill also receive serious injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in- f
lates - even with an Advanced A irbag
¢page 140.
A WARNING
-A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be serious ly injured and can be killed if
the front airbag inflates - even with an Ad­
vanced A irbag System.
- Although the Advanced Airbag System in your veh icle is designed to turn off the
front airbag when a rearward-facing child restraint has been instal led on the
front passenger seat, nobody can abso­
lutely g uarantee that dep loyment is im ­
possible in all conceivable situations that
may happen during the usefu l life of your
veh icle.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child aga inst the backrest, center
armrest, door, or roof.
-Always install rearward -facing ch ild re ­
straints in the back seat.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptiona l circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately insta ll th e rear-fac ing ch ild
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer .
A WARNING
If, in exceptional circumstances, you m ust
insta ll a forward -facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never p ut the forward-facing child re­
straint up against or very near the instru- ment panel.
~

-Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lling
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime w henever the ignition is sw itched
o n.
Advanced Airbag System components
The fron t passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack ­
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on .
The control un it mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on whe n a ma lfunction in t he sys tem
components is de tected. The function of the
airbag indicator light is described in greater
detai l below . Because the front passenger
seat contains important parts of the Ad ­
vanced A irbag System, you m ust take care to
prevent it from being damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/decele ration
to provide information to the Advanced Air­
bag System about the seve rity of the crash.
- An electronic co ntrol unit, with integrated
c rash se nsors for front and side impacts .
T he cont ro l unit " decides " whethe r to fire
the front airbags based on the inform ation
received from the crash senso rs . The contro l
