Assist Switching off completely
.,. Press the leve r into position @(clicked into
place), or
.,. Switch the ignition off.
The speed you sto red w ill be retained if the cruise
control has been switched off tempora rily . To re­
sume the stored speed, re lease the brake pedal
and pu ll the lever into position
(D .
The stored speed is erased when the cruise con­
trol is sw itched off comp letely or the ignit ion is
switched off .
A WARNING
You should only resume the stored speed if it
is not too high for existing traffic conditions.
Otherwise you risk an accident .
@ Tips
-If the brakes become too heated whi le driv­
ing, the cruise control switches off. If this
happens while driving downhill, you can re­
lieve the brakes by shifting into a lower
gear.
- When the cruise control is activated, ESC
sport mode cannot be switched on.
Audi adaptive cruise control
Description
Applies to vehicles: w ith Audi adaptive cruise control
Fig. 115 Detect ion range
The adaptive cruise control system is a combina­
tion of speed and distance regulation .
It assists
the driver by both regulating the speed and
maintaining a distance to the object ahead, with-
132
in the abilities of the system. If the system de­
tects an object, adaptive cruise contro l can brake
and acce lerate your vehicle. This makes driving
more comfortable both on long stretches of
highway and in stop-and-go traffic.
What can adaptive cruise control do?
The adaptive cruise control system uses radar
and a video camera. The radar is subject to desig­
nated system limits
i=> page 133 .
On open roads with no traffic , it functions like a
cruise contro l system. The stored speed is main ­
tained. When approaching an object ahead and
the system detects it, the adapt ive cr uise control
system automatically brakes to match that ob­
ject's speed and then maintains the stored dis­
tance . As soon as the system does not detect an
object ahead, adapt ive cr uise control acce lerates
up to the stored speed.
Within the limits of the system, adaptive cruise control can brake in stop -and -go traffic until the
vehicle is stat ionary and then begin driving agai n
under certain cond itions
i=> page 136, Driving in
stop-and-go traffic.
Which functions can be controlled?
When you switch adapt ive cru ise control on, you
can set the current speed as the "control speed"
i=> page 134, Switching on/off.
When dr iving, you can stop cruise control
i=> page 136 or change the speed c> page 136 at
any time .
You can also adjust the following settings :
- Distance
i=> page 137
-Dr iv in g program i=> page 138
-Dr iving mode c> page 138

Ass is t
- Always follow applicable traffic laws, use
common sense and select a distance to
vehicles ahead that takes the current traffic,
road and weather conditions into account .
(D Tips
Distan ce 3
is set automatically each time you
switch the ignition on. If you would like to set
another d istance as the standard setting, you
can have the
Ad apti ve cruis e control menu
added or enabled by an authorized Aud i dea l­

(D Tips
- ESC/ASR cannot be switched off or sport

- Mal functions in the Audi magnet ic r ide may
make it imposs ible to sw itch the ESC/ASR

Brakes
New brake pads
New brake pads do not ac hieve the ir full braking
effect during the first 250 mi (400 km) . They
must be "b roken in " fi rs t . However, you can com­
pensate for the slightly reduced bra king fo rce by
p ressing firmly o n the brake pedal. Avoid heavy
b raking during the break -in period .
Wear
Brake pad
wear depends largely on the way th e
ve hicl e is driven a nd on operat ing cond itions.
This is especially true if you are d riving frequently
in the c ity and on c urves o r wi th a sporty driving
style.
Operating noise
Noises may occur when bra kin g depend ing on the
speed , braking force and ou ts ide cond it ions s uch
as tempe rature and humidity .
Effect of water and road salt
In certain situations, for example after dr iving
through water, in heavy ra in, after ove rnig ht con­
densat ion or after washing your car, the b raking
Intellig ent Technology
effect ca n be reduced by moist ure o r ice on the
bra ke rotors and brake pads . The brakes must be
"d ried" first with a few caref ul brake applica­
tions.
At h igher speeds and w ith the wi ndshield wipe rs
tu rned on, the brake pads press against the brake
roto rs fo r a short amount of time. This action
wh ich is not felt by the dr iver happens at reg ular
interva ls and facilit ates a be tter reaction t ime for
the brakes in wet weather .
The braking effect can a lso be reduced if yo u are
driv ing on salted roads and yo u do not app ly the
brakes for long per iods of time . The layer of salt
o n the brake rotors and pads must be wor n off
first whe n the bra kes are applied .
Corrosion
Leaving the vehicle pa rked for long periods of
time, 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 brak ing or if there is
corrosion present, occasiona l heavy brak ing at
high speeds is recommended to clean the b rake
roto rs and pads<=>,& .
Brake system malfunction
if you notice that t he b rake pedal travel has sud­
denly gotten larger, t hen a b rake c ircuit may have
failed. Drive to an author iz ed Audi dealer or au­
thorized Audi Serv ice Facility immediately to have
t h e problem corrected. On the way there, drive
with red uced speed and keep in mind that a long
bra king d ista nce and increased pressu re on the
br ak e pedal w ill be necessary.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur . The b rake fluid level

Brake booster
The brake booster amp lifies the press ure you ap­
ply to the brake pedal. It on ly operates wh ile the

Intelligent Technology
All wheel drive (quattro)
Applies to vehicles: with all wheel drive
In all wheel drive, all four wheels ore powered.
General information
In all wheel dr ive, the driving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as well as
the current road conditions . A lso see
c> page 159, Electronic stabilization control
(ESC).
The all whee l drive concept is designed for high
engine power. Yo ur vehicle is exceptionally pow­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­
cautions
c> ,&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on veh icles w ith all wheel dr ive
c> page 269, Snow chains.
Replacing tires
For vehicles with a ll wheel d rive, only wheels with
the same rolling circumference should be used .
Avoid wheels with different tread depths
c> poge 260.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficu lt terrain . Also see<=)
page 302.
A WARNING
--Also, in veh icles with all whee l drive, adapt
your driving style to the current road and
traffic cond itions. Do not let the increased
safety prov ided tempt you into taking r isks.
