30 Driver in formation system
Electronic speed limiter*
Applies to vehicles: electro nic speed li miter
Your veh icle may be facto ry equipped with
tires that a re rated for a maxim um speed of
130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the
risk of s udden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your ve hicle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from go ing faster than the tire speed
rating . For mo re informat io n ~
page 236 .
If the engine control unit rece ives fa ulty vehi­
cle road speed s ignals, the Malfunction Ind i­
cator Lamp (MIU
¢'4 will illuminate . If th is
occurs, con tact the nearest aut horized Aud i
dea ler for assistance.
S model s
Your vehicle's top speed is e lectronically limit­
ed to 155 mph (250 km/h) .
If t he engine control unit receives fa ulty vehi­
cle roadspeed signa ls, the Ma lf u nction Indica­
tor Lamp (MIU
¢4 will illum inate. If th is oc­
curs, contact the nearest authorized A udi
dealer for assistance .
A WARNING
-
Always observe the posted speed limits
an d ad just yo ur speed to suit p revailing
road, t raffi c and wea ther conditions. Never
drive you r vehicle faster tha n the maxi­
m um speed rating of the tires insta lled .

-Starting on inclines in stop-and-go traf­
fic: To help prevent the vehicle from roll­
ing back when starting, press and hold
the brake pedal for several seconds when
the vehicle is stationary .
(D Tips
You can find out if your vehicle is equipped
with Hill Hold by checking at an authorized
Audi dealer or qualified repair facility .
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 display also turns on at
the same time. The indicator light./.
turns
off when the speed decreases below the
stored maximum 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 include 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 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 can set, change and delete the threshold
in the MMI.
"' Select: Systems or Car systems > Driver as­
sist> Speed warning .
Driving 79
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 6 mph
(10 km/h).
Cruise control system
Description
Applies to vehicles: with cruise control system
The cruise control system makes it possible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
.&_ 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, cruise control
should not be used in the city, in stop­
and-go traffic, on winding roads and
when road conditions are poor (such as ice, fog, gravel, heavy rain and hydro­
planing) -you could have an accident.
- Switch the cruise control
off temporarily
when driving in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal pre­
vents the cruise control from braking.
This is due to the control system being
overridden by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched 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 (Canadian models)
ison.

128 Driving safety
-Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Axle Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­
missible weight standards can cause the
vehicle to slide and handle differently .
- Please observe information on safe driv­
ing
~ page 121.
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 luggage compartment
lid left open. A child could crawl into the
vehicle through the luggage compart­
ment 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 .
(D 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 229.
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 12 7, Loading th e luggage com­
par tment.
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 .S 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 ..,_

correctly. ED L will switch on again automati ­
cally when conditions have returned to nor­
mal.
Electroni c inte raxle diff ere ntial lo ck */
s e le ct ive w heel t orqu e cont rol *
The electronic interaxle differential lock (front
wheel drive) or the selective wheel torque
contro l (all wheel drive) operates when driving
through curves. The front whee l on the inside
of the curve or both wheels o n the inside of
the curve are braked selectively as needed .
This minimizes s liding in the front wheels and
a llows for more precise driving through
curves. The app licab le system may not acti­
vate when driving in wet or snowy conditions .
Post-collision bra ke ass ist
"Post-collision brake assist" can ass ist the
driver during a collision by reducing the dan­
ge r of slipp ing and further co llision and by au­
tomatic braking.
"Post-collision brake assist" functions during
front, side and rear collis ions when the a irbag
control module a detects a trigger level and
the co llision takes place at a dr iv ing speed
faster than 6 mph (10 km/h). The braking of
the vehicle happen automatically via the ESC
as long as the ESC, the hydraulic brake sys­
tem, and the vehicle electrical system are not
damaged from the coll ision.
The fo llowing activ ities override the automat­
ic braking during a collision:
- If the dr iver presses the accelerator peda l.
T here is no a utomatic braking.
- When the force on the press brake pedal is
stronger than the b raking force initiated by
the system . The vehicle is manually braked .
- When the ESC is damaged and the "post­
collision brake assist" is not availab le.
A WARNING
- The ESC, ABS, ASR, EDL, electron ic inter­
axle d ifferential lock or select ive wheel
torque control cannot overcome the laws
of physics. This is espec ially important
on sl ippery o r wet roads.
If the systems
begin acting to stabili ze your veh icle, you
should immediately alter your speed to
match the road and traffic conditions . Do
not let the increased safety prov ided
tempt you into tak ing risks. This could
increase your risk of a collision.
- Please note the risk of a collision increas­
es when driving fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to objects ahead .
ESC, ABS, the brake assist system, EDL,
electronic interaxle differentia l lock or
selective whee l to rque control cannot
p revent coll is ions.
- Press the acce lerator pedal carefully
when acce le rat ing o n even, slippe ry sur­
f a ces such as ice and snow. The drive
wheels can spin even when these control
systems are installed and this can affect
driving stability and increase the risk of a
col lision.
(D Tips
- ABS and ASR only function correc tly
when all four wheels are eq uipped w ith
identical tires. Different t ire sizes can
lead to a reduction in engine power.
- Yo u may hear noises when the systems
described are working .
- If the
DJ or m] (USA models) !II] (Cana ­
da mode ls) indicator light appears, there
may be a malfunction
¢ page 22.

190 Smart T echnol ogy
Drive to an authorized Audi dea le r or qualified
repair facility immediately to have the ma l­
function corrected .
_& WARNING
Have the system malfunction repaired as
soon as possible by an authorized Audi
dealer or qualified repair facility, as th is in ­
creases the risk of an acc ident.
(D Tips
If the . or ,1:-ij indicator light on ly stays
on for a short time , you may continue driv­
ing .
ALL wheel drive
(quattro)
Appl ies to vehicles: wit h all whee l drive
In all wheel drive, all four wheels are pow ­
ered .
General information
In all wheel drive, the driving power is divided
between all four wheels. This happens auto­
mat ica lly depending on you r driv ing behavior
as we ll as the current road conditions. Re fer
to
¢ page 185, Electronic stabilization con ­
trol (ESC) .
The all wheel drive concept is designed for
h igh engine power . Yo ur vehicle is exception­
a lly powerful and has excellent driving charac ­
teristics bot h under normal driving conditions
and on snow and ice . A lways read and fo llow
safety precautions
c> & .
Wint er t ire s
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter
conditions . However, in winter we recommend
using winter or all season t ires on
all four
wheels, because this will improve the braking
effec t.
Snow cha in s
If there are snow chain laws, snow chains
must also be used on vehicles with a ll whee l
drive
c> page 241, Snow chains.
Replacing tire s
For vehicles with a ll wheel d rive, only wheels
with the same ro lling circumference should be
u sed. Avoid wheels with different tread
depths ¢
page 236 .
Offroad vehicle?
You r A udi is not a n offroad vehicle -there is
not enoug h ground clearance. For this reason ,
avoid difficu lt terrain. Refer to
c::> page 266.
A WARNING ~
- Also, in vehicles with a ll w heel drive,
adapt your driving sty le to the c urrent
road and traffic cond itions. Do not let
the increased safety provided tempt you into taking risks .
- The braking ability of your veh icle is lim­
ited to the traction of the wheels. In this
way, it is not different from a two wheel d rive vehicle . Do not be tempted to ac­
celerate to a high speed when the road is
slippe ry this inc reases the r is k of an acci­
dent.
- Note that o n wet s treets, the front
wheels ca n "hydrop lane " if driv ing at
speeds that are too high. Unlik e fron t
wheel drive vehicles, the engine does not rev higher sudden ly when the vehicle be­
g ins hydroplaning. For this reason, pay
attention to the road conditions regard­ less of your speed.
Energy management
The starting ability is optimized
The energy management system manages
the electrical energy distribution and optimiz­
es the availability of electrical energy for
starting the engine.
When a vehicle with a conventiona l energy
system is not d riven for a long time , the bat­
te ry is drained by equ ipment ( for example the
immobilizer) . In certain c ircumstances, there
cou ld may not be enough energy to start the
engine .

Driving and the
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 mil es
(1,000 kilometers):
.,. Do not use full throttle.
.,. Do not drive at engine speeds tha t are more
than 2/3 of the max imum permitted RPM .
.. Avoid high engine sp eeds .
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 ib le road or eng ine speed .
During and after break-in per iod
.,. Do not rev the engine up to high speeds
when it is cold. Th is app lies whether the
transmission is i n N (Ne utra l) or in gear.
After the break- in period
.. Do not exceed maximum engine speed un­
der any circumstances.
.,. Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ome ter scale
¢ 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
i n. How well this break-i n process is done de­
pends to a conside rable extent on the way the
ve hicl e is driven d uring the first 1,0 00 miles
(1 ,5 00 k ilome ters).
(D Note
Extremely h igh engine speeds a re auto­
ma tica lly reduced. However, t he se rpm
lim its are pr ogr amme d for an eng ine well
r u n- in, not a new engine .
Driving and the environment 193
@) For the sake of the environment
Do not drive with unnecessar ily hi gh en­
g ine speeds -upsh ifting ear ly saves f uel,
r educes noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
.&, WARNING
N ew tires tend to be slippery and mus t al­
so be "b roken -in" . Be s ure to remember
this dur ing t he f irst 350 m iles (500 kilo­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
New brake pads
Remember that new brake pads do not have a
full brak ing effect dur ing the first 250 m iles
(400 kilomete rs) afte r they a re install ed.
New brake pads have to be "burnished in" be­
fo re they have optima l grab¢ .&. .
D uring the brea k-in pe riod, you should avo id
putting severe loads on the brakes. Severe
l oads include , for example, sudden hard brak­
i ng, in particular at very h igh speeds or, for
example, on mounta in passes .
.&, WARNING
New b rake pa ds don 't have the best stop­
p in g p ower a nd must be "b ro ken -in " dur­
ing the ini tial 1 00 to 150 miles (15 0 to
2 00 kilometers) o f no rma l ci ty driving . You
can compensate for this by pressing t he
b rake peda l more fi rm ly . This also applies
l ater when new pads are installed.

Make sure that the cooling system has enough
f luid .
Tire pressure
When tow ing a trai ler, inflate the t ires of your
veh icle 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 trai ler and tire manufac­
turers' specifications.
Lights
Check to make sure both veh icle and trailer
lights are working properly.
Safety chains Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners . When you install safety
chains, make sure they wi ll not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
sepa ration from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obta in the best poss ible handling of vehicle
and trai le r, p lease note the following:
.. Do not tow a loaded tra iler when your car it ­
self is not loaded .
.. Be especially carefu l 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
Tow ing a loaded trailer with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at very
Trailer towing 199
low speeds on ly to avoid the risk of losing
steering contro l.
A "balanced " rig is easier to operate and con­
trol. This means that the tow vehicle should
be loaded to the extent possible and permissi­
ble, while keeping the trailer as light as possi­
ble under the c ircumstances. Whenever poss i­
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficu lt it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill .
Reduce vehicle speed
immediately if the trail­
er 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 veh icles .
Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­ gine braking effect to slow the vehicle . Use of
the brakes alone ca n cause them to overheat
and fail.
Coolant tempe rature
The coo lant temperature gauge¢
page 12
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
cli nes in a low gear at high engine speeds . Re ­
duce your speed immediately if the LEDs in
the top part of the display turn on.

A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greate r risk in an
accident. Never let anyone ride in yo ur car
