workshop and have the malfunction correctÂed.
- If the brake warning/indicator light does
not go out after a few seconds and the parkÂ
ing brake is released, or lights up while you
are driving, the fluid level in the brake fluid
reservoir is too low. If you believe that it is
safe to do so, proceed immediately at low
speed to the nearest authorized Audi dealer
or qualified repair facility and have the
brake system inspected.
- Always keep in mind that after several brake
applications, you will need greater pressure
on the brake pedal to stop your vehicle. Do
not rely on strained brakes to respond with
maximum stopping power in critical situaÂ
tions. You must allow for increased braking
distances. The extra distance used up by
fading brakes could lead to an accident.
PARK/( ®) Electromechanical parking brake
The warning/indicator light monitors the elecÂ
tromechanical parking broke.
If the indicator light- (USA models)/ .
(Canada models) turns on, the parking brake was
set .
- (USA models) • (Canada models) CauÂ
tion: Vehicle parked too steep
If the indicator light blinks and the message apÂ
pears, there is not enough braking power to keep
the vehicle from rolling. The brakes have overÂ
heated. The vehicle could roll away even on a
small incline.

- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road cond itions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because this increases the
risk of an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, h ighway ex its
or in construction zones.
- Please note that unconsciously "resting" your foot on the accele rator pedal p revents
the cruise control from braki ng. This is d ue
to the contro l system being over ridden by

Audi adapt ive cru ise control and brak ing gu ard
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydrop lanÂ
ing). Using the system under these condiÂ
t ions could resu lt in a col lision.
- Switch adaptive cruise control off temporaÂ
rily when driving in turn ing lanes, on exÂ
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situat ions.
- The adapt ive cr uise control sys tem wi ll not
brake by itself if yo u put you r foot on the acÂ
celerator pedal. Doing so can ove rride the
speed and distance regulation.
- When approach ing stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking g uard will have
limited function.
- The adapt ive cr uise control system and brakÂ
ing guard do not react to people, animals,
objects cross ing the road or oncoming obÂ
jects .
- The function of the radar sensors can be afÂ
fected by reflective objects such as guard
rails, the entrance to a tunnel , heavy rain or
ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly . The adapÂ
t ive cru ise control cannot s low or brake the
vehicle safely when you fo llow another veh iÂ
cl e too close ly. Always remembe r that the
automa tic brak ing funct ion c annot bring the
vehicle to a sud den or emergency stop unÂ
der these conditions.
- To prevent unin tended operation, always
switch ACC off when it is not be ing use d.
(D Note
The sensors can be displac ed by impacts or
damage to the bum per, whee l hou sing and
unde rbody. That could affe ct the adap tive

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
F ig. 99 Instrument cluster : approach warning
Braking guard uses radar sensors and a video
camera. It also functions within the lim its of the
system when adaptive cruise control is sw itched
off.
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own veh icle is traveling at a high speed
and approaching a vehicle up ahead that is movÂ
ing more slow ly . Braking guard does not react if it
cannot de te ct 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 avo id a collision. The indicator light.
in the d isplay comes on .
- The
approach warning is g iven when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is g iven, it may only be posÂ
sible to
avoid a co llis ion by swerving or braking
sharp ly. The indicator light. and indica tor in
the display will warn yo u about the danger
¢
fig. 99. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
all to the situation, braking guard will intervene
M N by braking. <( I.J "". rl I.O
"' N <.0 ll This is not a vailable in some coun tri es. rl
- If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
app ly ing the brakes.
- If you do not react to the acute warning, brakÂ
ing guard can brake with increasing force within
the limits of the system. This reduces the vehiÂ
cle speed in the event of a collision.
- The system can initiate maximum braking
short ly before a collision
1l . Full dece leration at
high speeds occurs only in vehicles with adapÂ
tive cruise control and s ide ass ist (pre sense
plus).
- If the braking guard senses that you are not
braking hard enough when a collis ion is imm iÂ
nent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imm inent ¢
page 185 .
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
¢ page 92, Settings in the Infotainment sysÂ
tem .
A WARNING
--
Lack of attention can cause collisions, other
accidents and ser ious personal injuri es. The
braking guard is an ass ist system and cannot
prevent a collision by itself. The driver must
always intervene . The driver is always responÂ
sib le for braking at the correct 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 comÂ
p lete control whenever necessary. Always
keep the safe and legal distance between
your veh icle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
example when approaching a stopped vehiÂ
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in trafÂ
fic).
-Always remember that the radar sensor for
the braking gua rd works on ly w ithin defined

Automatic transmission S tronic, tiptronic
Introduction
The automat ic transm iss ion is controlled elecÂ
tronically. The transmission upshifts or downÂ
shifts automatically depending on which drive
program is selected.
When a
moderate driving style is used, the
transmission selects the most econom ical driving
mode. The transmiss ion upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
The transmission switches to a sporty mode after a kick-down or when the driver uses a
sporty drivÂ
ing style
cha racterized by quick accelerator pedal
movements, heavy acceleration, frequent
changes in speed and traveling at the maximum
speed.
If desired, the driver can also select the gears
manually (tiptronic mode) ¢ page 111.
Various automat ic tr ansm issions may be instalÂ
