has been assigned a code. In case of a ma l­
function, the component will be identified
and the fault stored as a code in the contro l
module memory.
The MIL light may a lso illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem .
If the light illuminates after a refue lling,
stop the vehicle and make sure the fuel filler
cap is properly closed ¢
page 216.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBD) .
In order to connect the special diagnostic
equipment, push the plug into the Data L ink
Connector (DLC). The DLC is located to the
right of the hood release¢
fig. 16.
Your authorized Audi dealer or a qualified
service station can interpret the code and per­
form the necessary repair .
A WARNING
Do not use the diagnostic connector for
personal use . Incorrect usage can cause
malfunctions, which can increase the risk
of a coll ision!
Electronic speed limiter
-
Your veh icle may be factory equipped with
tires that are rated for a maximum speed of
130 mph (210 km/h). This is less than the
maximum speed of you r vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your veh icle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from go ing faster than the tire speed
rating. For more informat ion ¢
page 257 .
If the engine control unit receives faulty vehi­
cle road speed s ignals, the Malfunction Indi­
cator Lamp (MIU
¢'4 will illuminate. If this
occurs, contact the nearest authorized Aud i
dealer for assistance. S models
Your
vehicle's top speed is elect ron icall y limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty veh i­
cle roadspeed signals, the Malfunction Indica­
tor Lam p (MIL)
¢'4 will illuminate . If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.
_& WARNING
-= -
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather cond itions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed .

Speed warning system
Introduction
The speed warning system helps you to stay
under 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 exceeds the stored value by ap­ proximately 3 mph (3 km/h) . An indicator
light. (USA models)/ . (Canada models) in
the instrument cluster disp lay also turns on at
the same time. The indicator light./.
turns off when the speed decreases be low the
stored maxim um speed.
Setting a threshold is recommended if you
would like to be reminded when you reach a
certain maximum speed . Situations where you
may want to do so incl ude driving in a country
with a general speed limit or if there is a
specified maximum speed for winter tires .
@ Tips
Even though your vehicle is eq uipp ed w ith
a speed warning system, you sho uld still
watch the speedometer to make sure you
are not driving faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.

Engine sound*
The sou nd of the engine is adapted to these­
lec ted mode and ranges from subtle to sporty.
(D Note
- Make sure there is eno ugh clearance
above and below the veh icle when park­
i ng. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load condi ­
tions and changes to the driving modes,
which can affect clearance.
- When transporting the vehicle on a car
carrier, train, ship or by other means, on­
ly tie the vehicle down at the running
surface of the tires, which is the outer
circumference. Secur ing the vehicle at
the axle components, suspension struts
or tow ing eyes is not permitted because
the pressure in the air suspension struts
can change d uring transpor t. The vehicle
may not be sec ured s uff icient ly if this
happens.
- If you are going to tow a trailer, you
must activate the trailer ope rat ion mode

@ Tips
-In some mode ls, the m axim um vehicle
speed can on ly be reached in the Auto
and Dynami c modes.
- Se lecting the Dynami c mode results in
sporty shifting characteristics . The S
gear position engages automatically .
- In vehicles with sport differential*, the
D ynamic mode is deactivated when tow ­
ing a trai ler .
- In vehicles that have dynamic steering*,
operating noise is heard when starting or

A WARNING
To help prevent poisonous exhaust gas
from being drawn into the vehicle, always keep the rear lid closed while driving .
- Never transport objects larger than
those fitting completely into the luggage
area because the rear lid cannot be fully
closed.
- If you absolutely must drive with the rear
lid open, observe the following notes to
reduce the risk of poisoning:
- Close all windows,
- Close the power roof*,
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­ dows, the power roof* and the rear lid are
securely closed and locked to reduce the
risk of injury when the vehicle is not being
used.
- After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open. A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle .
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
Gj) Tips
-Air circulation helps to reduce window
fogging. Stale air escapes to the outside
through vents in the trim panel. 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 la­
bel is located on the driver's side B-pillar.
The tire pressure label lists the recom­
mended 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 manufactured.
For recommended tire pressures for nor­
mal load conditions, please see chapter
~page 244.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie-downs to secure your cargo prop­
erly~
page 132, Loading the luggage com­
partment.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy 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 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 collision like this.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
-Always use suitable mounting straps and properly secure items to the tie-downs in
.

194 Intelligent technology
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
smal l.
Anti -slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hills.
Electronic diffe rential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other wheels .
This function is available up to abo ut 75 mph
(120 km/h) .
I n extreme cases , ED L automat ic all y switches
off to help keep the brake on the braked whee l
from overheating . EDL will switch on again au­
tomatically when conditions have returned to normal.
Dynamic st eering*
On vehicles with dynamic steering* , ESC helps
stabilize the steering in critical situations .
Electronic interaxle differential lock */
s elective whe el torque control *
The electronic in teraxle d iffe ren tial lock (fro nt
wheel drive) or the select ive whee l torq ue
control (a ll-wheel drive) operates when driv­
ing throug h curves . The front whee l on the in­
side of the curve or both wheels on the inside
of the curve are braked selectively as needed.
T his minimizes sliding in the front wheels and
allows for more precise driving through
curves . The applicable system may not acti­
vate when d rivi ng in wet or snowy conditions.
_& WARNING
- E SC, ABS, ASR, EDL, dynamic steering*
and the E lec tronic interaxle differentia l lock
*/se lective whee l torque control*
cannot overcome the laws of physics.
This is especially important on slippery
or wet roads .
If the systems beg in acting
to stabilize your veh icle, you should im­
mediately chang e you r speed to match
the road and t raffi c conditions. Do not
let the increased safety provided by
these systems temp t you to take risks.
Doing so will increase the risk of a loss of
veh icle cont ro l, collision and serio us per­
sonal injur ies.
- Always adapt your speed to road, traffic
and weather conditions . The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and o n slippery or wet roads, and
when dr iv ing too close to vehicles up
a head . ESC, ABS, the brake ass ist sys­
tem, ED L, ASR, dynam ic steeri ng* and
the Electronic in terax le different ial
loc k*/se lective whee l torque control*
cannot prevent collisions .
- Always accelerate wi th spe cial care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
(D Tips
- ABS and ASR only wo rk correctly when
all four wheels are equipped with identi­
cal tires . D ifferent tire si zes can lead to a
reduction in engine powe r.
- You may hear noises when the systems descr ibed are working.
- If the ind icator light
Bl or fJl1 (USA
mode ls)l iiJ (Canada models) appears,
there may be a malfunction

Winter tires
When dr iv ing in the w inter, your ve hicl e w ith
a ll-whee l drive has an advantage,
even with
regular ti res . In winter road conditions it may
be advisable to mount winter tires (o r all-sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
all four
whe els .
See also c:> page 264, Winter tires.
Tire chains
Where tire cha ins are mandatory on certa in
roads, th is normally a lso applies to vehicles
with a ll-wheel drive
c:> page 265, Snow
chains.
Replacing wheel s/tir es
Vehicles w ith all-wheel drive must a lways
have tires of the same size . Also avoid tires
with d ifferent tread depths. For details see
page
c:> page 257, New tires and replacing
tires and wheels.
Off-Road driv ing?
Your Audi does not have enough ground clear ­
ance to be used as an off-road ve hicle . It is
therefore best to avoid rough tracks and un ­
even terrain as much as possible. Also refer to
c:> page 201.
A WARNING
Always adjust your driving to road and traf­
fic conditions . Do not let the ext ra safety
afforded by all-wheel dr ive tempt you into
taking extra risks.
- Alt hough the all-whee l dr ive is
very ef­
fec tive, a lways remember that b raking
c ap aci ty is limited by tire traction. Yo u
sho uld the re fo re not dr ive at excessive
speeds on icy or slippery road su rfaces.
- O n wet road s urfa ces, be c areful not to
drive too fast because the front wheels
cou ld begin to sli de on top of the water
(aq uaplaning) . If this sho uld occ ur, you
will have no warn ing from a sudden in­
crease in engine speed as with a front­
w heel d rive vehicle. A lways drive at
speeds w hich are suited to the road con­
ditions -risk of c rash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventiona l energy system
is not driven for a long period of t ime, t he bat­
te ry is discharged by idling current consume rs
(e .g. immobili ze r). In certa in circumstan ces it
ca n res ult in the re be ing insu ffic ien t energy
available to start the eng ine.
Intelligent energy management in your vehi­
cl e ha ndles the dist rib ution o f electr ica l ene r­
gy. Start ing abili ty is m arke dly improved and
the life of the battery is extended .
Bas ica lly, energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic energy management .
Battery diagnosis
Battery diagnosis continuously determines
the state of the batte ry. Sensors determine
batte ry voltage, batt ery cu rr e nt and battery
tempe ratu re. This de termines the cur ren t
sta te o f cha rge and t he power o f th e battery.
Idling current management
Idli ng cur rent management reduces energy
consumpt ion while the vehicle is standing .
With the ig nition sw itched off, it controls the
energy supp ly to the variou s ele ctri ca l compo ­
nen ts. Da ta from ba ttery d iagnos is is co nsid­
ered.
Depend ing on the batte ry's state of cha rge,
i ndivid ual con sume rs are g radually turned off
to prevent excessive discharge o f the battery
and th us main tain starting capabi lity.
Dynamic energy management
While the vehicle is being d riven, dynamic en­
ergy ma nagement distr ib utes the energy ge n­
era ted a ccord ing to t he needs of the indivi du-
al components .
It regula tes consumption, so
t h at more electrical energy is not being used ..,.

Driving and
environment
The first 1,000 miles
(1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometers ):
.,. Do not use full throttle.
... Do not d rive at engine speeds that are more
than 2/3 of the max imum permitted RPM.
... Avoid high engine speeds.
From 600 to 1,000 mile s (1 ,000 to
1,500 kilometers):
... Speeds can gradually be increased to the
max imum pe rm iss ible road or eng ine speed .
During and after break-in period
.,. Do not rev the eng ine up to high speeds
when it is cold. Th is app lies whether the
transm ission is in N (Neutra l) or in gear.
After the break-in period
... Do not exceed maximum engine speed un­
der any circumstances.
.,. Upshift into the next hig her gear
before
reaching the red area at the end of the tach­
ometer scale
c:> page 11.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving parts have been broken
in . How well this break- in process is do ne de­
pends to a conside rable extent on th e way the
ve hicl e is driven during the first 1,0 00 miles
(1, 500 k ilome ters).
0 Note
E xtremely high engi ne speeds are auto­
mat ica lly reduced. However, these rpm
lim its are progr amme d for an engine well
r u n- in, not a new engine .
{® For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds - upshifting ear ly saves fuel,
reduces no ise and protects the environ­
ment.
, New tires
If your vehicle is runni ng on new tires, drive
part icularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
A WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be s ure to remember
this dur ing the fi rst 350 mi les ( 500 kilo ­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
braking .
New brake pads
Remember that new brake pads do not have a
full bra king effect dur ing the fi rst 250 m iles
(400 kilomete rs) afte r they a re insta lled.
New brake pads have to be "burnished in" be­
fo re t hey have optima l grab
c:> A .
During the break- in period, you should avoid
putting severe loads on the brakes. Severe
l oads include, for example, sudden hard brak­
i ng, in particular at very high speeds or, for
example, on mounta in passes .
A WARNING
New b rake pa ds don't have t he bes t stop­
pi ng power and mus t be "broke n-in " dur­
i ng the in iti al 1 00 to 150 mi les (150 to
20 0 k ilometers) of no rma l city driving . You
can compensate for this by pressing the
br ake peda l mo re f irm ly . This also applies
l ater when new pads are installed.
