Electronic speed
limiter
Your vehicle may be factory equipped with tires that are rated for a maximum speed of
130 mph (210 km/h) . Th is is less than the
maximum speed of your vehicle. To reduce the
r isk of sudden tire failure and loss of control if
the veh icle is operated at excessive speeds,
your veh icle also has an elect ronic speed limit­
er. The electronic speed limiter prevents yo ur
vehicle from going faster than the tire speed
rating. For more information~
page 206.
If the engine control unit receives fau lty vehi­
cle road speed signals, the Malfunction Indi ­
cator Lamp (MIL)¢• will illuminate . If this
occ urs, contact the nearest authorized Audi
dealer for assistance.
A WARNING
-
Always observe the posted speed limits and adjust your speed to suit prevailing
road, t raff ic and weather conditions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires insta lled.

Speed warning system
Overview
T he speed warning system helps you to keep
your driving speed below a set speed limit.
The speed warning system warns if the driver
exceeds a prev iously stored maximum speed .
A warning tone will sound as soon as the vehi ­
cle speed exceeds the set speed by about
3 mph (3 km/h). At the same time , an indica­
tor lamp
(mj (USA models) / ISJ (Canada mod­
e ls) will light up in the instrument cluster dis ­
p lay and the driver message
Spe ed limit
wa rning exceeded.
wi ll appear. The indicator
l amp
1mj / i•j will go out when the speed
drops below the set speed lim it aga in.
Setting a thresho ld is recommended if you
wou ld like to be reminded when you reach a
certain maximum speed . Situations where yo u
may want to do so include driving in a country
with a general speed limit or if the re is a
specified max imum speed for winter tires .
(D Tips
Even though your vehicle is equipped with
a speed warning system, you should st ill
watch the speedometer to make sure you are not driving faster than the speed lim it.
Setting speed limit
You can set , change and delete the threshold
in the MMI.
.,. Se lect :
I CAR I funct ion button > S ystem s or
Car System s control button > Vehicle set­
tings > Speed warning .
You can set any thresho ld 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
Description
The cruise cont ro l system makes it poss ible to
drive at a constant speed start ing at 15 mph
(20 km/h).
The speed is kept constant by modifying en­
gine powe r or th rough an active brake inte r­
vention.
A WARNING
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your vehicle and other vehicles.
- For reasons of safety, cr uise control
should not be used in the city, in stop ­
and-go traffic, on winding roads and
when road cond it ions are poor (such as
ice, fog, gravel, heavy rain and hydro­
plan ing) -you could have an accident .
- Sw itch the cruise control off temporar ily
when dr iv ing in turning lanes, h ighway
exits or in constr uction zones.
- Please note that unconsc iously "resting"
your foot on the accelerator pedal pre­
vents the cruise control from braking .
This is due to the control system be ing
overridden by the dr iver's acceleration .
- If a b rake system malfunction s uc h as
overheating occurs when the cruise con­
trol system is swi tched on, the braking
function in the system may be switched off . The other cruise control functions re­
main active as long as the indicator light
II (US models) !l'I (Canada mode ls) is
on .
(D Tips
-The cruise control system is ideal for
stretches w ith speed limits. The driver is
responsib le for adhering to the correct
speed.
- The cru ise control remains act ive when
shift ing gears .

to reduce the risk of injury when the vehi­
cle is not be ing 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. Be ing trapped in a vehicle can
lead to serious persona l injury.
- Never let children play in or around the vehicle .
- Never let passe ngers r ide in the luggage
compartment . Ve hicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- Air c irculation helps to reduce window
fogging. Sta le air escapes to the outside
th rough vents in the trim pane l. Be su re
to keep these slots free and open.
- The t ire pressure must correspond to the
load. The t ire pressur e is shown o n the
tire p ress ure label. The tire pressure la­
bel is loc ated on the d river's s ide B-pi ll a r.
The t ire pressure label lists the recom­
mended cold ti re inflat ion pressu res for
the vehicle at its maximum capacity
weig ht and the tires that were on you r
vehicle at the time it was manufactured.
For recommended t ire pressures fo r nor­
mal load conditions, please see chap ter
c:>page 199.
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
c:> page 100, Loading the luggage com­
partment.
In a coll is ion, the laws of phys ics mean that
even smalle r items that are loose in the vehi­
cle will become heavy missiles that can cause
Dr iving S afel y 101
serious injury. Items in the ve hicle possess en ­
ergy which vary with vehicle speed and the
weight o f the item . Vehicle speed is the most
s ignificant factor.
Fo r example, in a fronta l collision at a speed
of 30 mph (48 km/h), the forces acting on a
10 -lb (5 kg) object a re about 20 times the
no rmal weight of the item. This means that
the weight of the item would sudden ly be
about 200 lbs. (90 kg) . You can imag ine the
i njur ies that a 200 lbs . (90 kg) item flying
fr eely th ro ugh the passenger compar tme nt
c ould cause in a co lli sion like this.
A WARNING
We ak, dam aged or improper str aps used
to secure items to tie -downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury .
-Always use s uita ble mount ing stra ps and
properly secu re items to the tie-downs in
the l uggage compa rtme nt to he lp pre­
vent items from shift ing or f ly ing fo r­
ward as dangerous missiles .
-When the rea r seat backrest is folded
down, a lways use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to hel p prevent items from fly ing for­
ward as dangerous missiles into the pas­
s enger compartment.
- Never attach a chi ld safety seat te th er
strap to a t ie- down .

Anti-slip r egulation (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 ED L brakes wheels that are spinn ing and
transfers the drive power to the o ther d rive
wheel or whee ls if the vehicle is equipped with
all-wheel drive* . This function is available up
to about 60 mph (100 km/h).
I n extreme cases , ED L automat ica lly switches
off to help keep the brake on the braked whee l
from overheating . EDL wi ll switch on again au­
tomatically when conditions have returned to normal.
El ectron ic inte ra xle diff ere ntial lock */
se lec tive wheel t orque contr ol*
The electronic interaxle differential lock (front
wheel drive) or the select ive wheel torque
control (all-wheel drive) operates when driv­
ing through curves. The front wheel on the in·
side of the curve or both wheels on the inside
of the curve are braked select ively as needed .
This minimizes s lid ing in the front wheels a nd
allows for more p rec ise driving through
curves. The app licab le system may not acti­
vate when driving in wet or snowy conditions .
A WARNING
-ESC, ABS, ASR, EDL, the electronic inter­
axle differentia l lock* /selective whee l
torque control* and the hill descent as­
sist cannot overcome the laws of physics.
Th is is especially important on slippery
o r wet roads . If the systems begin acting to stabilize your vehicle, you should im­
mediately change your speed to match
the road and traffic conditions. Do not let the increased safety provided by
these systems tempt you to take r isks .
Doing so will increase the risk of a loss of
veh icle cont ro l, collision and ser ious 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 on slippery or wet roads, and
when driving too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL and the electronic inter­
axle d ifferential lock*/selective wheel
torque control* cannot prevent colli­
sions .
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow .
The drive wheels can spin even w ith
these assistance systems t hat cannot al­
ways he lp to reduce the risk of loss of ve­
hicle control.
(D Tips
- ABS and ASR only wo rk correct ly when
all four wheels are equipped with identi­
cal tires. D ifferent tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working .
-If the ind icator light DJ or Ell (USA
mode ls)/ lCO)J there may be a malfunction~

- If you damage the front s poiler, or if you
insta ll a different spoiler, be su re the air
flow to the front brakes is not obstruct­ ed. Otherwise the brake system could
ov erhe at r educi ng the eff ect iveness of
t h e enti re brak e system.
- Failure of one brake ci rcuit will impair
the braking capability resulting in an in­ creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­
est author ized Audi dealer or qualif ied
wor kshop.
- Never let the vehicle rol l to a stop w ith
the engine shu t off.
- If the brake booster is not working, the
brake pedal must be pressed conside ra­
bly harder to make up for the lac k of
booster assistance.
Electromechanical
steering
The electromechanical steering supports the
driver 's steering movements .
Power steering adapts electronically based on
the vehicle speed.
Ind icator light s and messages
• Steering fault! Do not drive vehicle !
If this indicator light tu rns on and stays on
and this message appears, t he power steering
may have fa iled.
Stop the vehicle in a safe locat ion as soon as
possib le . Do
not continue driving . See your
author ized Audi dealer or other qua lified re­
pa ir facility for assistance .
If the indicator light turns on, the steer ing
may be more d ifficu lt to move or more sensi­
tive than usual. The steer ing may also be at an
angle when dr iving st raight . Drive slowly to you
r authorized Audi dea ler or
qualified workshop to have the ma lf u nction
corrected.

Driving with your
quattro
Applies to veh icles: w ith all-w hee l d ri ve
With all-wheel drive, all four wheels are driv­
en.
General information
Wi th a ll-w heel d rive, power is dis trib ute d to
all four wheels . This happens automatically
depending on your driving style and the road
conditions at the time . See a lso
¢ page 153.
The all -whee l dr ive concept is des igned for
high eng ine power. Your veh icle is except ion ­
ally powerfu l and has excellent d riving charac­
terist ics both under normal driving conditions
and on snow and ice. Always read and follow
safety precaut ions¢ .&..
Winter tires
When driving in the winter, yo ur vehicle with
all-wheel drive has an advantage, eve n wit h
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing: these tires must be mounted on
all four
wheel s.
See also ¢ page 210, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this norma lly also app lies to ve hicles

with all-wheel drive¢ page 211, Snow
chains .
Replacing wheels /tire s
Vehicles w ith all-wheel drive mus t always
h ave tires o f the same size. Also avoid t ires
with different tread depths. For details see
page
c::> page 206, New tires and replacing
tires and wheels.
A WARNING
Always adjust your driving to road and traf­
fic condit ions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Although the all-wheel dr ive is very ef­
fective, always remember that braking capacity is limited by t ire traction . You
should therefore not dr ive at excess ive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
c ou ld beg in to s lide on top of the water
(aquaplaning). If this sho uld oc cur, you
will have no warning from a sudden in­ crease in engine speed as with a front­
wheel drive vehicle. A lways drive at
speeds which are suited to the road con ­
ditions -risk of crash.
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 conventional energy system
is not driven for a long period of time , the bat­
tery is discharged by idling cu rrent consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insufficient energy
M avai lab le to start the engine . N

Intelligent energy management in your veh i­
cle handles the d istribution of elec trical ener­
gy . Starting abi lity is markedly improved and
the life of the battery is extended .
Intellig ent technolog y 159
Basica lly, energy management consists of
b att ery diag nosis , id lin g cur rent man age­
ment
and dyn amic en ergy m anag ement.
Batte ry diagnosis
Battery diagnosis continuously determines
the state of the battery . Sensors determine
battery voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the batte ry .
Idlin g current manag ement
Id ling current management reduces energy
consumption while the vehicle is standing.
With the ig nition switched off, it controls the
energy supply to the various electrical compo­ nents. Data from battery diagnosis is cons id­
ered.
Depending on the battery's state of charge ,
individual consumers are gradually turned off
to prevent excessive discharge of the batte ry
and thus maintain starting capability .
Dynamic energy manag ement
While the vehicle is being driven, dynamic en­
ergy management distributes the energy gen ­
erated according to the needs of the individ u­
al components . It regulates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery .
(D Tips
-But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited.
- If start ing ability is threatened, the indi­
cator light (•) ;ippears

What you should know
The highest priority is given to maintaining
starting capability .
The battery is severe ly taxed in short-distance
driving , in ci ty traff ic and during the cold time

(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the first 600 mile s (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 .
From 600 to 1 ,000 miles (1,000 to
1,500 kilometers ):
.. Speeds can gradually be increased to the
maximum perm iss ible road or eng ine speed .
During and after br eak-in period
.. Do not rev the eng ine up to h igh speeds
when it is cold. Th is applies whether the
transmission is in N (Neutral) or in gear.
Afte r the break- in peri od
.. Do not exceed max imum eng ine speed un­
der any circumstances .
.. Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ometer scale
c.> page 10.
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 done de ­
pends to a considerable extent on the way the
ve hicl e is driven du ring the first 1,000 miles

Driving and environment 161
@) For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds - upshifting ear ly saves f uel,
reduces noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
very carefully for the first 350 miles (500 ki lo­
meters) after fitting.
.&, WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be sure to remember
this dur ing the f irst 350 m iles (500 kilo­
meters) . Brake gently . Avoid fo llowing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
Avoid damaging the
vehicle
When you are d rivi ng on poo r roads, or over
cu rbs, steep ramps, etc., make certa in that
low- ly in g parts s uch as spo ile rs and ex ha ust
system parts do not bottom o ut and get dam ­
aged.
Th is is espec ially true for veh icles with low­
s lung chassis (spo rts chas sis)* and fully load ­
ed vehicles.
Catalytic converter
It is very important that your emission con­ trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
