Assist Electronic speed limiter*
Applies to veh icles: with electronic speed limiter
Your vehicle may be factory equipped with ti res
that are rated for a maximum speed of 130 mph
(210 km/h) . T his is less than the maximum speed
of your vehicle . To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed
limiter prevents your vehicle from going faster
than the tir e speed rat ing . For more information
~page 221.
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL)
¢4 will illuminate . If this occurs,
contact the nearest a utho rized Audi dealer for as­
sistance .
A WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions . Never drive your
vehicle faster than the maximum speed rating of the tires installed.
Speed warning system
Introduction
The speed warning system helps you to stay un­
der a specified maximum speed.
-
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
You will hear a warning tone when your speed ex­
ceeds the stored value by approximately 3 mph
(3 km/h) . Th e. (USA models)/. (Canada
models) indicator light and the message
Speed
limit exceeded!
appear in the instrument cluster
disp lay at the same time . The ./. indicator
light turns off when the speed decreases below
the stored maximum speed.
Setting a thresho ld is recommended if you would
like to be reminded when you re ach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
94
al speed limit or if there is a specified maximum
speed for winter tires.
(D Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit .
Setting the threshold
You can set, change and delete the threshold in
the MMI.
.. Select: the I MENU I button >Car> Systems*
contro l button > Driver assistance > Speed
warning.
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h) . Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
· Description
Applies to vehicles: with cruise control system
The cruise control system makes it poss ible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modify ing engine
power or through an act ive brake intervention.
A WARNING
- Always pay attention to the traffic around
you when the cruise control is in operation.
You are a lways responsible for your speed
and the distance between your vehicle and
other vehicles.
- For reasons of safety, cruise contro l should
not be used in the city, in stop-and-go traf­
fic, on winding roads and when road condi­ tions are poor (such as ice, fog, gravel,
heavy rain and hydroplaning) -you could
have an accident .
- Switch the cruise control off temporarily
when driv ing in turning lanes, highway exits
or in construction zones .

-Please note that unconsciously "resting"
your foot on the accelerator pedal prevents the cruise control from braking. This is due
to the control system be ing overr idden by
the driver 's acceleration .
-If there is a b rake system malfunction such
as overheating when the speed warning sys­
tem is switched on, the braking function in
the system will be deactivated. The remain­
ing speed warni ng system fu nctions will re­
ma in active, as long as the~ (USA mod ­

{i) Tips
-The cruise cont ro l system is idea l for
stretches with speed limits. The driver i s re­
spons ible for adhering to the cor rect speed.
- The cruise cont ro l rema ins active when

Audi pre sense basic
Description
App lies to vehicles: wit h Aud i pre sense basic
The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or higher .
The following functions can be triggered under certain conditions within the limits of the sys­
tem:
- Tensioning of the safety belts (for example,
during heavy braking): the front safety belts
have reversible belt pretensioners. If a col lision
does not occur, the safety belts loosen slightly
and are ready to trigger again .
- Closing the windows and the sunroof* (for ex­
ample, when over- or understeering): the w in­
dows and the sunroof* close until there is only
a small gap open .
Audi drive select: the deployment time is adapt­ ed in dynam ic mode.
_&. WARNING ~
The pre sense basic cannot overcome natural
physical laws . It is a system des igned to assist
and it cannot p revent a coll ision. Do not let

Electronic stabilization
control (ESC)
Description
The E lectronic Stabilization Contro l (ESC) reinfor­
ces driver safety. It reduces the risk of slipping
and improves driving stability. ESC detects criti ­
cal s ituations such as the vehicle oversteering
and understeering or the wheels a re spinning.
The vehicle is stabilized by applying the brakes or
reducing engine torque. Once the ESC is activat­
ed, the indicator light
DJ blinks in the instru­
ment cluster.
The fol low ing systems a re integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
i ng. The vehicle can still be steered even during
hard braking . Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal ind icates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking d is­
tance . It increases braking power when the driver
presses the brake pedal quickly in emergency s it­
uations. You must press and hold the brake pedal
unti l the dangerous sit uation is ove r. In vehicles
with adaptive cruise control *, the brake assist
system is more sensit ive if the distance detected
to the vehicle ahead is too small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive whee ls
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up inclines.
Intelligent Technology
Electronic differential lock (EDL)
The EDL brakes whee ls that are spinning and
trans fers the drive power to the other drive wheel
or whee ls if the vehicle is equipped with all wheel
drive*). This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over ­
heating. The vehicle is still working correct ly. EDL
will switch on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
Selective wheel torque control
Selective wheel torque control is used when dr iv­
i ng on curves. The front wheel on the inside of
the curve o r both wheels on the inside of the
curve are braked selectively as needed . This al­
lows more precise driving in curves .
Automatic post-collision braking system
The "Automat ic post -collision braking system"
can help to reduce the ris k of sliding and of other
collisions after an accident. If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
T he vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the brak ing force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electr i­
cal system are not funct ion ing .
A WARNING
-The ESC and its integrated systems cannot
overcome the limits posed by natural phys i­
cal laws. This is especially important on slip­
pery or wet roads .
If the systems begin act­
ing to stabilize your vehicle, you should im-
mediately a lter your speed to match the ..,.

A WARNING
You should only switch sport mode on or switch ESC/ASR off if your driving ab ilities and
road condit ions perm it.
- The stabilization function is limited when
sport mode is switched on. The dr iving
wheels could sp in and the veh icle could
swerve, especially on slick or slippery road
surfaces.
- There is no vehicle stabilization when ESC/
ASR are switched off.
(D Tips
- ESC/ASR cannot be switched off or sport
mode cannot be sw itched on if the cru ise
control system* or the adapt ive cruise con­
trol* is switched on.
- Malfunctions in the Audi magnetic r ide may
make it impossible to sw itch the ESC/ASR
off or to switch spo rt mode o n.
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km). They
must be "broken in" f irst. Howeve r, you can com­
pensate for the slightly reduced braking force by
press ing firmly on the b rake pedal. Avoid heavy
braking during the break -in period.
Wear
Brake pad wear is large ly dependent on the way
the veh icle is d riven and on operating co nditions.
This is especially t rue if you are driving frequent ly
in the city and on cu rves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, b rak ing force and o utside conditions s uch
as tempe rat ure and h umid ity.
Effect of water and road s alt
In certain situat ions, for example after driving
throug h wate r, in heavy ra in, after overn ight con­
densat ion or afte r wash ing you r car, the braking
In te llig ent T echnolog y
effect can be reduced by moisture or ice on the
brake rotors and brake pads . The brakes must be
"dried" first with a few careful brake applications.
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the b rake
rotors for a short amount of time . This action
wh ich is not felt by the driver happens at regular
intervals and facilitates a better reaction t ime for
the brakes in wet weather.
The braking effect can a lso be reduced if you are
driv ing on salted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first whe n the brakes a re applied .
Corro sio n
Leav ing the ve hicle parked for long periods of
t ime, low mileage and avoiding heavy braking can
contribute to corros ion on the brake rotors and
dirty brake pads.
If you usua lly avoid heavy b raking or if there is
corrosion present, occas ional heavy braking at
high speeds is recommended to clean the brake
rotors and pads¢,&.
Brake sy stem malfunct ion
if you notice that the b rake pedal travel has sud­
denly gotten larger, then a brake circ uit may have
failed. Drive to an authorized Audi dealer or au ­
thori zed Audi Service Facility immediately to have
the problem cor rected. On the way there, dr ive
with reduced speed and keep in mind that a long
braking distance and increased pressu re on the
brake pedal will be necessa ry.
Low br ake fluid level
When the brake f lu id level is low, malfunct ions in
the brake system may occur. The brake flu id leve l
is electronically mon itored.
Brake boo ste r
The brake booster amplifies the pressure yo u ap­
ply to the brake peda l.
It only works when the en-
gine is running.
