Audi adaptive cruise control and braking guard
When the adaptive cruise control is turned on,
you must press the clutch to shift gears (as usu­
al). When sh ifting normally or when pressing the
clutch, the adaptive cruise control remains
turned on.
After you have engaged the gear, you do
not need
to press the gas pedal. The adaptive cruise con­
trol accelerates automatically if necessary .
If you press down on the clutch for too long or
shift/coup le im properly, the adaptive cruise con­
trol may turn off automat ica lly.
@ Tips
You cannot turn on the adaptive cruise control
during a shifting operation.

Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 96 Detection range
What can Audi adaptive cruise control do?
The adaptive cruise control works in conjunction
with a rada r sensor installed in the front of the
veh icle¢
page 89, fig. 93, which is subject to
des ignat ed system limits¢
page 91. Stationa ry
objects are disregarded.
On open roads w ith no traff ic, adaptive cruise
control wo rks like a regu lar cruise control system.
The stored speed is mainta ined. When approach­
ing a moving vehicle detected up ahead, the
adaptive cruise control system automatically
slows down to match that vehicle's speed and
then maintains the distance that the driver previ­
ously stored. As soon as the system does not de- tect a vehicle up
ahead, adaptive cruise control
acce lerates back up to the stored speed.
Which functions can be controlled?
When you switch adapt ive cr uise control on, you
can set the current speed as the "control speed"
¢ page 91, Switching on and off.
When driving, yo u can stop cru ise contro l
¢page 93 or change the speed ¢page 92 at
any time.
You can also set the distance to the object ahead
and set the adaptive cruise control dr iv ing pro­
gram ¢

speeds below 20 mph (30 km/h), will auto­
matically accelerate the vehicle to 20 mph
(30 km/h), which is the minimum speed
that can be set.
@ Tips
-If you switch the ign it ion or the adaptive
cruise control off, the set speed is erased
from the system memory.
- The electronic stabilizat ion control (ESC)
and the anti-slip-regulation (ASR) are auto­
matically turned on when the adaptive
cruise control is turned on. Both systems
cannot be turned off if the adaptive cruise
control is turned on .

sary, how they work and how to adjust and wear
them correctly .
~ Read all the informat ion that fo llows and heed
all of the instructions and WARNINGS .
A WARNING
Not wearing safety belts or wearing them im­
properly increases the r isk of serious personal
injury and death.
- Safety belts are the sing le most effective
means availab le to reduce the r isk of serious
injury and death in automobile accide nts .
For yo ur protection and tha t of your passen­
gers, always correct ly wear safety belts
when the veh icle is moving.
- Preg nant wome n, injured, or physically im­
paired pe rsons mu st also use safety belts .
Lik e all ve hicle occu pants, t hey are more
likely to be seriously injured if they do not
wea r safety belts . The best way to protect a
fetus is to protect the mother -th rougho ut
the enti re pregnancy.
Number of seats
Your Audi has a total of four seating positions:
t wo in the fron t and two in the rear. Each seating
position has a safety belt.
A WARNING
N ot wea ring safety belts or wea ring them im­
prope rly i ncreases the r is k of se rious personal
injury and death.
- Never st rap more than one pe rson, includ­
ing small children, into any belt. It is espe­
ci ally d angerous t o place a safe ty belt over a

Airbag syste m
detail below . Because the front passenger seat
contains important parts of the Advanced Airbag
System, you must take care to prevent it from be­ ing damaged. Damage to the seat may prevent
the Advanced Airbag for the front passenger seat
from doing its job in a crash .
The front Ad vanced Airb ag System con sis ts
of the follow ing :
-Crash sensors in the front of the veh icle that
measure veh icle acceleration/decelerat ion to
provide information to the Advanced Airbag
System about the severity of the crash .
- An electronic control unit, with integrated crash sensors for front and side impacts. The
control un it "decides" whether to fire the front
airbags based on the informa tion rece ived from
the crash sensors. The con trol un it also "de­
cides" whether the safety be lt pretensioners
shou ld be activated.
- An Advanced Airbag wi th gas generator and
control valve for the driver inside the steering
whee l hub.
- An Advanced Airbag with gas generator and
control va lve inside the instrument panel for
the front passenger.
- A weight -sensing mat under the upholste ry
padding of the front passenger seat cushion
that measures the total weight on the seat. The information registered is sent continuously to
the electronic control un it to regu late dep loy­
ment of the front Advanced Airbag on the pas­
senger side.
- An airbag monitoring system and indicator
light in the instrument cluster
r=> page 139.
-A sensor in each front seat registers the dis­
tance between the respect ive seat and the
steering wheel or instrument panel. The infor­
mation registered is sent cont inuously to the
electron ic co ntro l unit to regulate deployment
of the front Advanced Airbags.
- T he
PA SSENGER AIR B AG OFF light comes on
and stays on in the center of the instrument
pane l
c>page 139, fig . 135 and tells you when
the front Advanced A irbag on the passenger
side has been turned off.
- A sensor below the safety belt la tch for the
front seat passenge r to measure the tension on
136 the safety belt
. The tension on the safety be lt
and the weight registered by the weight-sens ­
ing mat help the control unit "decide" whether
the front a irbag for the front passenger seat
should be turned
off or not c> page 130, Child
restraints on the front seat -some important
things to know.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and transm its this info rmat ion to the elect ro ni c
cont ro l unit .
_&. WARNING
Damage to the fron t passenger seat can pre­
vent the front a irbag from working properly.
- I mproper repa ir or d isassembly of the front
passenger and driver seat will p revent the
Advanced Airbag System from functioning properly.
- Repairs to the front passenge r seat must be
performed by qualified and properly trained
wo rkshop personne l.
- Never remove the front passenger o r driver
seat from the vehicle .
- Never remove the upho lstery from the front
passenger seat.
- Never d isassemble o r remove par ts from the
seat or disconnect w ires from it.
- Never carry sharp obje cts in yo ur pocke ts or
place them on the seat. If the weight-sens­
ing mat in the passenger seat is p unctured
it cannot work properly.
- Never carry things on you r lap or carry ob­
jects on the passenger seat. S uch items can
increase the weight registe red by the
weight-sensing mat and send the wrong in­ formation to the airbag contro l unit.
- Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, preventing them and the airbag sys­
tem from wo rking prope rly.
- Never p lace seat covers or rep lacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced Air­ bag System from recogniz ing ch ild

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not funct ioning prop­
erly cannot provide supplementa l protect ion
in a frontal crash.
- If the airbag indicato r light ~ page 19
comes when the vehicle is be ing used, have
the system inspected immed iate ly by your
authorized Audi dealer . It is possible that
the a irbag will inflate when it is not s up­
posed to, or wi ll not inflate when it should.
A WARNING
If the front airbag inflates, a ch ild without a
child restraint, in a rearward-facing child safe­
ty seat or in a forward-facing child restraint that has not been proper ly installed will be
ser iously injured and can be killed.
- Even though your veh icle is equipped with
an Advanced Airbag System, make certa in
that all ch ild ren, especially 12 years and
Airbag syste m
younger, a lways ride on the back seat prop­
erly restra ined for their age and size.
- Always install forward o r rear-facing child
safety seats on the rear seat -even with an
Advanced Airbag System.
- If you must install a rearward-facing child
safety seat on the front passenger seat be­
cause of except iona l circumstances and the
PASSENGER AIR BAG OFF light does not
appear and stay on, immediately install the
rea r-facing chi ld safety seat in a rear seating
position and have the airbag system inspect­
ed by your authori zed Audi dealer .
- A tight tether or o ther s trap on a rea rward­
facing ch ild restraint attached to the front
p assenger seat can put too much pressure
on the weight-sens ing mat in the seat and
register more weight than is actually on the
seat. The heavier weight registe red can
make the system work as though an adult
were on the seat and deploy the Advanced
Airbag when it must be suppressed causing
serio us or even fatal injury to the child.
- If, in exceptiona l circumstances, you must
install a forward-facing child restraint on
the front passenger seat, always move the seat into its rearmost pos ition in the seat's
fore and aft ad justmen t range, as fa r away
from the airbag as possib le. The b ackrest
m ust be adjus ted to an upr ight position.
Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the time
whenever the ignit ion is switched on.
A WARNING
--
- If the PASSENGER AIR BAG OFF light does
not go out when an adult is s itting on the
front passenger seat after tak ing the steps
described above, make sure the adult is
p roperly seated and restrained at one of the
rea r seat ing pos itions.
- Have the airbag system inspected by your
author ized Audi dealer befo re transpo rting
anyone on the front passenger seat.

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of sk id­
d ing and loss of veh icle control.
It works only
when the engine is runn ing . ESC detects certain
d ifficult driving situations, including when the ve­
h icle is beginn ing to sp in (yaw) out of control and
he lps you to ge t the vehicle back u nder cont rol by
selectively braking the wheels, and/or reducing
engine power and providing steering assistance
to help hold the vehicle on the driver's intended
course. The indicator light
liJ in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
d itions you may come up against. For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of friction of the road surface. Whe n
there is a section of d ry road that is s uddenly cov ­
ered wi th wa ter, s lush or snow, ESC cannot per­
form the same way it wou ld on the d ry surface . If
the vehicle hydroplanes (rides on a cushion of wa ­
ter instead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been i nterrupted and the
ve hicle cannot be braked or steered. Dur ing fast
cornering, particula rly on w inding roads, ESC
cannot a lways deal as effect ively with d iff icu lt
d riving situat ions than at lower speeds. When
towing a trailer, ESC is not able to he lp yo u regain
con trol as it wou ld if yo u were not towing a trail­
er .
A lways adjust you r speed and dr iving style to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limi ts, increase the
170
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention .
Instead, ESC improves the possibility of keeping
the ve hicle under control and on the road dur ing
extreme maneuvers by using the dr iver's steering
i nputs to help keep the vehicle going in the in­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can p rov ide any assistance, you may not expe ri­
ence the benefi ts of ESC.
ESC is switched o n all the time. In ce rtain s itua­
tions when you need less traction, you can switch
off ASR by p ress ing the button [!]¢
page 171,
fig. 153 or ¢page 171, fig. 154. Be s ure to
swi tch ASR on again when you no longe r need
l ess traction .
The following system s are integrated in the ESC:
Anti- lock braking s ystem (ABS )
ABS prevents the wheels from locki ng up when
braking. The vehicle ca n still be steered even dur­
i ng hard braki ng . Apply steady pressure to the
brake pedal. Do not pump t he pedal. A pu lsing in
t h e b ra ke peda l ind icates that the system is he lp­
i ng yo u to b ra ke the vehicle.
Brake assist system
The brake ass ist system can decrease brak ing dis ­
ta nce. It increases braking power when the d river
presses the bra ke peda l quickly in emergency sit­
u at ions. You must press and hold t he b ra ke peda l
u nt il t he s ituation is ove r. In vehicles with adap­
tive cru ise contro l*, the bra ke assist system is
more sensitive if the distance detected to the ve ­
hicle ahead is too sma ll.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the d rive wheels
begin to spi n and adap ts the force to the ro ad
cond it ions . This makes it eas ie r to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL bra kes whee ls that a re spinn ing and
t ransfers the dr ive power to the othe r drive wheel
o r whee ls if the ve hicle is equippe d wi th a ll-wheel
drive*. T his function is not available at higher
speeds .

Trailer mode
Tire pressure
When tow ing a trailer, inflate the tires of your ve­
hicle to the cold tire pressure listed under " Full
load" on the label located on the driver's side B ­
pillar (visible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off . Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be su re trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains shou ld cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with a trailer always requires extra care
and consideration.
To obtain the best possible handling of vehicle
and trai ler, please note the following:
.. Do not tow a loaded trailer when your car itself
is not loaded .
.. Be especia lly careful when passing other
vehicles.
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Towing a loaded trai ler with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
182
A "balanced" rig is easier to operate and contro l.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, wh ile
keep ing the trailer as light as possible under the
c ir cumstances. Whenever poss ible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle load ing considerat ions .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or w ind
cond it ions are unfavorab le - particularly when
go ing downh ill.
Reduce veh icle speed
immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing tra ilers are lower than for regular
vehicles.
Always apply brakes early. When dr iving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge¢ page 10 must
be observed carefully. If the needle moves close
to the upper end of the scale, reduce speed im­
med iately and/or turn off the air conditioner .
If the coolant temperature warning light . in
the instrument cluster starts flashing, pull off
the road, stop and let the engine
idle for about
two m inutes to prevent heat build-up .
&_ WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.

(D Note
- Fuels containing a high pe rcentage of etha­
no l such as ESQ and E85 may only be used in
vehicles with f lexible fuel engines. Using
high ethanol fuel in veh icles not equ ipped
with flexible fuel engines can cause severe
engine damage.
- Methanol fuels which do not meet these re­ quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the spec i­
fied criter ia in this chapter .
- If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier .
- Do not use fuel for wh ich the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those spec ified are not the respon­
s ibility of Audi and are not covered under
the New Vehicle o r the Emission Cont ro l
System Warranties.
- If you experience a loss of fue l economy o r
driveability and pe rformance problems due
to the use of one of these f uel b lends, we
r ecommend that yo u switch to unb lended
fuel.
Ethanol fuel (Bio-ethanol)
Applies to vehicles: with flexible fuel engine
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of the fuel filler flap.
Vehicles w ith f lexible fuel engines may be operat­
ed with bio-ethanol fuels such as E85 (85% e tha ­
nol and 15% gasoline) or with unleaded gasoline
(91 AKI/ROZ 95) . The vehicle may also be operat­
ed with a m ixt ure of these fuels.
Fu el and R efu elin g
Your f uel consumption wi ll increase when using
bio-ethano l fue ls due to the lower amount of en­
ergy contained per unit vo lume in ethano l.
Warming up the fle xible fuel engine in low
t e mperatu res
Due to the chemical composition of b io-ethanol,
a certain amount of fue l ends up in the engine oil
when driving short distances in
very low temper­
atures. This fuel evaporates again when the en­
gine is warmed up .
II Please w arm up eng ine .
If the driver message appears in the instrument
cluster disp lay, drive with a warm engine to re ­
duce the oil leve l.
(D Note
-Never fill with methano l or with a h igher
percentage of b io-ethanol than 85% (E85).
A highe r percentage of bio-ethanol in the
fue l can cause damage to the engine or to
the fuel system.
- If you use on ly E85, it is recommended to
fill the fue l tank complete ly w ith unleaded
premium grade gasoline every 5,000 miles.
- If you experience starting, rough id le or hes­
itat ion driveab ility problems, fill the fuel
tank complete ly w ith unleaded premium
grade gasoline and drive it normally unt il
the gaso line is used. See your author ized
Audi dea ler if the problem pe rsists.
- Inform your author ized Audi dealer that you
are operating or have operated the vehicle
w ith E85.
