On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your eng ine system has been as­
signed a code . In case of a malfunction, the com­
ponent will be identified and the fault stored as a
code in the control module memory .
The MIL light may also illuminate if there is a leak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop ­
erly closed
¢ page 214.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD) .
In order to connect the special diagnostic equip ­
ment, push the plug into the Data Link Connector
(DLC) . The DLC is located to the right of the hood
release
c> fig . 17.
Your author ized Audi dealer or a qualified service
station can interpret the code and perform the necessary repair.
A WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!
Electronic speed limiter
Your veh icle may be factory equipped with t ires
that are rated for a maximum speed of 130 mph
(2 10 km/h). This 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 rating . For more information
¢page 243 .
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
L amp
(Mil) Ill will illuminate . If this occurs,
contact the nearest authorized Audi dealer for
assistance .
Instruments and indicator lights

Your vehicle 's top speed is elect ronically lim ited
to 155 mph (250 km/h).
If the engine control unit receives faulty vehicle
roadspeed signals, the Malfunction Indicator
Lamp (MIL)¢• will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
assistance.
A WARNING
-A lways 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.

Driving
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). An indicator light . (USA models) .
(Canada models) in the instrument cluster dis­
p lay also tur ns on at the same time. The indicator
light •• turns off when the speed decreases
be low the stored maximum speed.
Setting a threshold is recommended if you would
like to be reminded when you reach a certa in
maximum speed. Situations where you may want
to do so include driving in a country with a gener ­
al speed limit or if there is a specified maximum
speed for winter tires.
(D Tips
Even though your vehicle is equipped with a
speed warning system, you should still watch
the speedometer to make sure you are not
driving faster than the speed limit.
Setting the threshold
You con set, change and delete the threshold in
the MMI.
.,. Select:
ICARI function button > Car systems
contro l button > Driver assist > 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 S mph (10 km/
h).

Head-up Display*.
The speed is kept constant via an engine output
adjustment or active brake intervention. ..,_

Engine sound *
The sou nd of the engine is adapted to the select­
ed mode and ranges from subt le to sporty.
(D Note
- Make sure there is enough cle arance above
and below t he vehicle when parking. The
height of the vehicle can change once it is
parked due to temperature f luctuations,
changes to the load conditions and changes
to the driving modes, which can affect clear­
ance.
- When transporting the vehicle on a car car­
rier, tra in, ship or by other means, only t ie
the vehicle down at the running surface of
the tires, which is the outer circumference.
Securing the vehicle at the axle compo­
nents, suspe ns ion struts or towing eyes is
not permitted be cause the press ure in the
air suspension struts can change dur ing
transport . The vehicle may not be secured
sufficiently if this happens .
-If yo u are going to tow a tra ile r, you m ust
activate the trailer operation mode
<:!;>page 202.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the
auto and
dynamic modes.
- Se lecting the
d ynami c mode resu lts i n spor­
ty shifting characteristics. The S gear posi­
tion engages a utomatically.
- In vehicles that have dynamic steering*, op ­
erating noise is heard when starting or stop­ ping the engine. This does not indicate a
problem.

- In vehicles w ith sport differential*, the dy­
namic mode is deactivated when towing a
trailer .
Selecting the driving mode
You con choose between Comfort, Auto , Dynamic
and Individual .

Driving safety
-Never leave your vehicle unattended espe­
cially with the rear lid left open. A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
- Air circulation helps to reduce window fog­
ging . Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
- The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B·pillar. The tire pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter ¢
page 247.
Tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items .
Use the tie-dow ns to secure your cargo properly
¢ page 135, Loading the luggage compartment .
In a coll ision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury . Items in the vehicle possess energy which
vary with vehicle speed and the weight of the item. Vehicle speed is the most significant factor.
For example, in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10 -lb
(4 .5 kg) object are about 20 times the normal
136
weight of the item. This means that the weight
of the item would suddenly be about
200 lbs. (90 kg) . You can imagine the injuries
that a 200 lbs. (90 kg) item flying freely through
the passenger compartment could cause in a col­
lision like th is.
A WARNING
Weak, damaged or improper straps used to
secure items to tie-downs can fail during hard
braking or in a collision and cause serious per­
sonal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent items from shifting or flying forward as dan­
gerous missiles.
- Never attach a child safety seat tether strap
to a tie-down.

Reporting Safety Defects
Applicable to U.S.A.
If you believe that your vehicle
has a defect which could cause a
crash or could cause injury or
death, you should immediately in­
form the National Highway Traffic Safety Administration (NHTSA) in
addition to notifying Audi of
America, Inc.
If NHTSA receives similar com­plaints, it may open an investiga­
tion, and if it finds that a safety
defects exists in a group of
vehicles, it may order a recall and remedy campaign. However,
NHTSA cannot become involved in
individual problems between you,
11>

In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL w ill switch on aga in a utomati­
cally when conditions have returned to normal.
Ste ering recommendat ion
The ESC helps to stabilize the ve hicle by chang ing
the s teering torque .
I n vehicles with dynamic steering*, ESC also
h e lps to s tabilize the stee ring in critical s itua­
tions.
Selective wh eel torqu e control
Select ive whee l torque control is used when driv­
in g on curves . T he front wheel on the inside of
the cu rve or both wheels o n the inside of the
curve are br aked selec tively as needed . This al ­
l ows more precise driv ing in curves . The applica­
b le system may not activate when driving in wet
or snowy conditions.
Automatic post-collision braking system
The "Automatic post-co llision bra king system"
can help to reduce the ris k of slid ing and of other
coll is ions after an accident. If the airbag contro l
module detects a col lision above a certain vehicle
speed, the vehicle is b raked by t he ESC.
The vehicle does not b rake automatica lly if :
- the driver p resses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greate r than the brak ing force
that wou ld be initiated by the system, or
- the ESC, the brake system or the vehicle electri ­
ca l system are not f unction ing .
Sma rt Technology
A WARNING
- The ESC and its integrated systems cannot
overcome the limits posed by natural physi­
cal laws . This is especia lly important on s lip­
pe ry o r we t roads .
If the systems beg in act­
i n g to stab iliz e your ve hicle, yo u should im­
mediately change yo ur speed to ma tch the
road and traffic con dit ions . Do not let the
increased safety provided by these systems
tempt you to take r isks. Do ing so will in­
crease the r isk of a loss of vehicle contro l,
coll is ion and serious pe rsonal in juries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle increases when driving too fast, especially through curves and on
slippery or wet roads, and when driving too
close to vehi cles up ahead. The ESC and its
i n teg ra ted systems ca nnot alw ays preven t
coll is io ns -the re is s till a risk of accide nts!
- Always accelerate w ith specia l care on even,
smooth s urfaces su ch as those that are wet
or covere d wi th ice and snow. The d rive
whee ls can spin eve n wit h these assistance
systems that cannot always help to reduce
the risk of loss of vehicle contro l.
(D Tips
-ABS a nd ASR only wo rk cor rec tly when all
four wheels a re equipped wi th identi cal
tires. Diffe rent tire s izes can lead to a red uc­
tion i n engine power .
- You may hear noises when the systems de ­
scribed are working .

Driving with your
quattro
With All Wh eel Drive , all four wh eels are driven .
General information
With All W heel Drive, power is dis tribute d to all
four wheels . This happens automatically depend­
ing on your dr iving style and the road conditions
at the time . See also¢
page 190 . With the sport
d ifferent ial*, power d istr ibution to the rear
wheels is variable and can be adjusted with Audi
d rive select*
¢ page 106. Always read and fo llow
safety preca utio ns ¢ ,&. .
Winter tires
When drivi ng in the w inter, you r vehicle with All
Wheel Drive has an advantage, even with reg ular
tires. In winter road cond itions it may be adv isa­
b le to mount w inte r tir es (or a ll-season tires) for
i mproved d riveab ility and bra king : these tires
must be mounted on
all four wheels . See also
¢ page 251, W inter tires.
Snow chains
Where snow chains are mandatory on certain
roads, this normally also a pplies to vehicles w it h
All Whee l Dr ive ¢
page 251, Snow chains.
Replacing wheels /tires
Veh icles w ith All Wheel Drive must always have
tires of the same s ize. A lso avo id tires wi th d iffer­
ent tread depths. For detai ls see page
¢ page 243.
Off-Road driving?
Your Aud i does not have e nough g round clear­
a nce to be used as an off-road vehicle . It is there­
fore best to avoid rough tracks and uneve n ter­
r ain as m uch as possible . Also refe r to
¢page 197.
_& WARNING ,~ -
Always adjust you r driv ing to road and t raffic
conditions . Do not let the extra safety affo rd­
ed by All Wheel Drive tempt you into taking
extra risks.
Sma rt Technology
- Although the A ll Whee l Drive is very effec­
tive, always remember that braking capacity
is limited by t ire tract ion. You shou ld there­
fore not dr ive at excessive speeds on icy or
slippe ry road surfaces .
- On wet road surfaces, be careful not to dr ive
too fast because the front wheels could be­
g in to slide on top of the water (aquap la n­
ing) . If th is should oc cur, you will have no
warn ing from a sudden increase in engine
speed as with a front-wheel d rive vehicle.
Always d rive at speeds which are suited to
the road conditions -risk of c rash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus op timizes the availa­
bility of electrical energy for starting the engine .
If a vehicle with a conventional energy system is
not driven for a long pe riod of time, the battery is
discharged by id ling curre nt consumers (e.g. im­
mobilize r) . In certain circumstances i t can resu lt
in t he re being i nsufficien t energy ava ilable to
sta rt the engine.
Intelligent energy manageme nt in you r vehicle
hand les the distribution of electrical energy .
Start ing ability is markedly improved and the life
of the ba ttery is ex tended.
Bas ica lly, energy management cons ists of
bat ­
tery diagnosis , idling current management
and
dynamic energy management .
Battery diagnosis
Battery d iagnosis continuously dete rm ines the
state of the battery. Sensors determine battery
vo ltage, battery current and battery tempera­
tu re. This de termines the current state o f ch arge
and the power of the battery .
Idling current management
Idling current management reduces energy con­
sumption while the vehicle is standing. With the ..,_

Driving and the
environment
Breaking in
New eng ine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km).
For the first 600 miles (1 ,000 kilometers):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than 2/3 of the max imum permitted RPM .
"' Avoid high eng ine speeds.
From 600 to 1 ,000 miles (1,000 to 1,500
kilometers ):
"' Speeds can gradually be increased to the maxi­
mum pe rm issib le road or e ngine speed.
During and after b reak-in period
"' Do not rev the engine up to high speeds when it
is cold . This applies whether the transmission is
in N (Neutral) or in gear .
After the bre ak-in period
"' Do not exceed maximum engine speed under
any circumstances .
"' Upshift into the nex t higher gear
before reach­
ing the red area at the end of the tachometer
sca le
c:::;, page 10.
During the first few hours of driving , the eng ine's
internal friction is higher than later when all the
mov ing parts have been broke n in. How well this
b reak-in process is done depends to a considera­
b le exte nt o n the way the veh icle is d rive n du ring
the first 1,0 00 miles (1,500 kilome ters).
(D Note
E xtremely high eng ine speeds a re au toma ti­
cally reduced. However, t hese rpm li mits are
p rogr amme d fo r an eng ine well run-in, not a
new engine .
Driving and the envir onment
{® For the sake of the environment
Do not drive with unnecessarily high engine
spe eds -upshifting early saves fuel, red uces
no ise and protects the environment.
New tires
If your vehicle is runni ng on new tires, drive par­
t icularly careful for the first 3S0 m iles (500 kilo ­
meters) after fitting .
_&. WARNING
New tires tend to be slippe ry and mus t also
b e "bro ken- in". Be sure to remembe r th is dur­
i ng the first 350 m iles ( 500 k ilome ters).
Brake gent ly . Avoid following closely behin d
other vehicles or other s ituations that might
require sudden, hard braking.
Avoid damaging the
vehicle
When you are dr iv ing on poor roads, or over
curbs, steep ramps, etc., make certai n that low ­
ly ing parts such as spo ile rs and exhaust system
parts do not bottom o ut and get damaged .
This is espec ially true for veh icles with low-s lung
chass is (sports c hass is)* and fully loaded
vehicles .
Catalytic converter
Applies to: vehicles with gasoline engine
It is very important that your emission control
system (catalytic converter) is functioning prop ­
erly to ensure that y our vehicle is running in an
environmen tally sound manner.
"' Always use lead-free gasoline c:::;, page 212,
F uel supply .
"' Never run t he tank down all the way to emp ty.
