creases the risk of collisions and serious
personal injury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to br ing your vehicle to a safe
stop and ma kes it
even more necessary
to pay close attention to traffic.
- Always obey applicable traffic laws, use
good judgment, and select a safe follow­
ing distance for the traffic, road and
weather conditions .

Audi braking guard
Descript ion
Applies to vehicles: with Audi adaptive cruise control
Fig. 113 Instrument cluste r: approach 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
guard 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 will
not be able to avoid a collision. The indicator
light
I 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 possib le to avoid a collision
by swerving or braking sharply . The indicator
l ight
I and indicato r in the display will warn
you about the danger
¢ fig. 113 . You will al­
so hear an acoustic signal.

at all to the situat ion , Braking guard will in-

- If a coll is ion is imminent, the system wi ll
fi rst 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 under 20 mph (30 km/h), the sys­
tem can initiate a comp lete deceleration

).
- If the braking guard senses that you are not
brak ing hard enough when a co llision 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 MMI
¢ page 101, 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 responsible for braking at the cor­
rect time .
- Always pay close attent ion to traffic,
even when the braking guard is switched
on. Be ready to intervene and be ready to
take complete 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 t raffic).

Audi adaptive cru ise control and brakin g guar d 101
-Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that
may prevent the proper detection of oth­
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not be promptly detected or may not be de­
tected at al l.
- Reflective surfaces includ ing crash barr i­
ers or tunnel ent ran ces may impair the
function of the radar sensor.
- You can cance l the braking that is initiat­
ed by the system by braking yourself, by
accelerating noticeab ly or by swerving.
- Bra king guard error messages
<> page 101.
-Keep in mind that braking guard can
brake unexpectedly . Always secure any
ca rgo or objects that you are transport­
i ng to reduce the risk of d amage or in ­
ju ry.

180 Intelligent technology
ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti-slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering" and
e lectronic interaxle differentia l lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certa in s ituations whe n you need
l ess t raction, you can switch off ASR by p ress­
i ng the bu tto n
[ru ¢ fig. 167 or ¢ fig. 168. Be
sure to sw itch ASR on ag ain when you no lon­
ger need less trac tion.
Anti -lock braking system (ABS)
ABS prevents t he wheels from locking up
when braking. The veh icle can still be st eered
even d uring ha rd b rak ing . Apply steady p res­
sure to the br ake pedal. Do no t pu mp the ped­
a l. A puls ing in t he bra ke peda l ind icates that
the system is he lping yo u to b rake the vehicle .
Brake assist system
The brake assist system can decrease bra king
d ista nce. It increases braking powe r w hen the
d river p resses the brake pedal quickl y in eme r­
gency situa tions . You mus t press and ho ld the
brake peda l until the situation is over. In
ve hicles with adaptive cruise contro l", the
brake assist system is more sensit ive if the
d ista nce detected to t he vehicle a head is too
smal l.
Anti-slip regulation (ASR)
ASR reduces engi ne power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic diffe rential lock (EDL )
The EDL brakes wheels that are spinning and
tra nsfers t he d rive powe r to the other d rive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h).
In extreme cases, EDL a utomatica lly switches
off to help keep the bra ke on the braked whee l
from overheating. EDL will switch on aga in au­
tomatically when conditions have returned to
normal.
Dynamic steering*
On vehicles wi th dynam ic s teering *, ESC he lps
sta bilize the steer ing in crit ica l sit uat ions.
Electronic interaxle differential lock*/
selective wheel torque control*
T he ele ctroni c in te raxle di fferentia l lock ( fron t
whee l drive) o r th e se lective whee l torque
control (all -whee l drive) operates when driv­
ing t hro ugh cu rves. The front wheel on the in­
s ide of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
Th is mi nimizes sliding in the front wheels and
allows for more precise d rivi ng through
cu rves . The a ppl icable syste m may not acti­
vate when dr iv ing in wet o r snowy cond itions.
_&. WARNING
- E SC, A BS, ASR, ED L d ynam ic steering *

This is especia lly important on slippery
or wet r oads. If the systems beg in acting
to stabilize your veh icle, yo u should im­
mediately change you r speed to match
the road and t raff ic conditions. Do not
let the increased safety prov ided by
t hese systems temp t you to ta ke r is ks.
Doing so will increase the risk of a lo ss of
veh icle cont ro l, col lision an d ser io us per­
sonal injur ies.
- Always adapt your speed to ro ad, traff ic
an d wea ther conditions . The risk of los ­
ing contro l of t he vehicle increases when
driving too fast, es pec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
a head. ESC, ABS, the brake ass ist sys­

Chamois are not suitable for drying the top .
Neve r use gasoline, spot remover, benzene,
pa int thinner o r so lvents to remove spots. We
recommend that you only use cleaners espe­
cially formu lated for use on convertible tops,
and that you follow the produce use directions
caref ully. Authorized Audi deals can provide
deta iled information.
A WARNING
Always read and heed all WARNINGS and
the information on
¢ page 194.
@ Note
Never use a high-pressure power washer to
clean the power top.
Wind deflector
App lies to vehicles: with wind def lector
Clear the wind deflector with water or, if it is
heav ily soiled, a chemically neutral cleaning
solut ion .
A WARNING
Always read and heed a ll WARNINGS and
the information on¢
page 194.
Sensors and camera lenses
-Remove snow with a hand brush and remove
ice with a de-icing spray that does not con­
tain solvents .
- Clean the sensors (adapt ive cruise control*,
parking system*) with a cleaning solution
that does not conta in solvents and a soft
cloth .
@ Note
- If you wash you r vehicle with a pressu re
washer,
- make sure there is enough distance to
sensors in the rear bumper .
- do not clean the camera lenses and the
area around them with the pressure
washer . - Never use warm or hot wate
r to remove
snow or ice from the camera lens . This
cou ld cause the lens to crack.
- Never clean the camera lens with abra­
sive products.
Waxing and Polishing
W axin g
A good wax coating protects the vehicle paint
to a large extent against the environmental
factors listed under¢
page 194, Washing and
even against slight scratches.
You can use a liquid car wax to protect your
paint as soon as one week after your vehicle
has been delivered.
Even if you regularly use a
w axin g process in
automatic car washes, we recommend that
you manually apply a coat of wax to give the
paint extra protection, part icularly if water no
longer beads on the clean paint .
Protect plastic body parts with car wax in the
same way as the vehicle
body.
During warm weather dead insects tend to
collect on the front bumper and on the for­
ward area of the hood . They are much easier
to remove from pa int that is waxed
often.
Polishing
Polish yo ur vehicle only if the paint has lost its
shine and the gloss cannot be brought back
with wax .
If the polish used does not conta in preserva­
tive compounds, the paint must be waxed af­
terwards.
A WARNING
A lways read and heed all WARNINGS and
other information ¢
