In o rder to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC) . The DLC is located to the
right of the hood release ¢
fig. 18.
Your authorized A udi dealer or qualified work­
shop can interpret the code and perform the necessary repa ir.
A WARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a coll is ion!
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). Thi s is may be less than
the maximum speed of your ve hicle. To red uce
the risk of sudden ti re failure and loss of con ­
trol if the vehicle is operated at excessive
speeds, your vehicle has an e lectronic speed
limiter. The electronic speed limiter prevents
your veh icle from going faster than the t ire
speed rat ing . For more informat ion
¢ page 246 .
If the engine control unit rece ives fa ulty vehi ­
cle roadspeed signa ls, the Ma lfunction Indica­
tor Light (MIL)
¢..ij w ill illuminate . If this oc­
curs, contact the nearest authorized Audi
deale r for assistance.
A WARNING
-
Always observe the posted speed limits
and ad just yo ur speed to suit p revail ing
road, t raff ic and weather conditions . Never
drive your vehicle faster than the maxi ­
mum speed rating of the tires insta lled .
Dri ver information di spla y 31

88 On the road
vehicle speed exceeds the set speed by about
3 mph (3 km/h). At the same time, a warning
symbol appears in the d isp lay . The symbol's
appeara nce m ight be d ifferent in some mod­
els.
The speed warning system has one or two*
warn ing thresholds that f unct ion independ ­
ently of each other and that have somewhat
d ifferent purposes:
Speed warn ing 1
You can use speed warning 1 to set the maxi­
m um speed w hile you are driv ing. T his setting
will remain in effect until you turn
off the igni­
tion, assuming that you have not changed or
reset the setting.
The . (USA models)/ . (Canada models)
speed warning symbol in the warning 1 dis­
p lay appears whe n you exceed the maximum
speed. It goes out when the speed fa lls below
the stored max imum speed .
The speed warning symbo l w ill also go out if
the speed
exceeds the stored max imum speed
by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed
is deleted .
Sett ing speed warning 1
c::> page 88.
Speed warning 2*
Sto ring warning 2 is recommended if you al­
ways
want to be reminded of a certain speed,
for example when yo u are traveling in a coun­
try that has a general maximum speed limit,
or if you do not want to exceed a specified
speed for winter tires.
The . (USA mode ls)/ . (Canada mode ls)
speed warning 2 symbo l appears in the dis­
play when you exceed the stored speed lim it.
Unlike warning 1, it will not go out until the
vehicle speed drops below the stored speed
lim it.

(D Tips
Even tho ugh your vehicle is equipped with
a speed warning system, you should st ill watch the speedome
ter to ma ke s ure you
are not dr iving faster than the speed limit .
Speed warning 1: setting a speed limit
Warning threshold 1 is set by the ISETI but­
ton.

134 Driving Safely
A WARNING
Always make sure that the doors, all win­
dows, the sunroof and the rear lid are se ­
curely 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.
(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
c:>page238.

Tie-downs
Applies to vehicles: with tie -downs
The luggage comportment is equipped with
four tie-downs to secure luggage and other
items .
Use the tie-downs to secure your cargo p rop­
erly
c:> page 133, Loading the luggage com ­
portment .
In a collision, the laws of physics mean that
even smaller i tems 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
the luggage compartment to help pre­
vent items from shifting or flying for­
ward as dangerous missiles.
- When the rear seat backrest is folded
down, always use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to help prevent items from flying for­
ward as dangerous missiles into the pas­
senger compartment.
- Never attach a child safety seat tether
strap to a tie-down .

-Always acce lerate with specia l care on
even, smooth surfaces s uch 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 help to reduce the risk of loss of ve­ hicle control.
(0 Tips
- ABS and ASR on ly work correctly when
all four wheels are equ ipped w ith ident i­
ca l tires. Different tire s izes can lead to a
reduct ion i n eng ine power.
- You may hear noises when the systems
described are wo rking .
- If the indicator light D] or m!S (USA
models) ;tiJ (Canada models) appears,
the re may be a malfunct ion

Driving with your
quattro ®
Applies to vehicles: with a ll-wheel drive
With all-wheel drive, all four wheels are driv­
en.
Gener al inform ati on
W ith all-wheel drive, power is distributed to
all four wheels . This happens automatically
depending on your dr iving style and the road
conditions at the t ime. See also
c:> page 185.
A center different ial distr ibutes the dr iv ing
power var iably to the front and rear axle . It
works together with selective wheel torque
control, which activates when driving throug h
curves
c:> page 186. With the spo rt d ifferen ­
tial*, power dist ribution to the rear wheels is
variable and can be adjusted with drive select
c:> page 113.
The all-wheel drive concept is designed for
h igh engine power. Yo ur vehicle is exception ­
ally powerful and has exce llent driving charac ­
teristics both under normal driving conditions
and on snow and ice. Always read and fo llow
safety precautions
c:> A .
Winter t ir e s
When driv ing in the w inter, your veh icle w ith
all-wheel drive has an advantage,
even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
a ll four
w heels . See also c:> page 250, Winter tires .
Intellig ent technolog y 191
Tire chain s
Where tire chains are mandatory on certain roads, this no rma lly also applies to veh icles
with all-wheel drive
c:> page 251, Snow
chains.
Replacing wheels /tires
Vehicles with a ll-wheel drive must always
have tires of t he same s ize. A lso avoid tires
with different tread depths . For detai ls see
page
c:> page 246, New tires and replacing
tires and wheels .
Off-Road driving?
You r A udi does no t have enough ground clear ­
ance to be used as an off-road vehicle .
It is
therefore best to avoid rough tracks and un ­
even terrain as much as possib le . Also refer to
c:> page 194.
A WARNING
Always adjust your dr iving to road and traf­
f ic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire traction. You
should therefore not d rive at excessive
speeds on icy or slippe ry road surfa ces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
co uld begin to slide on top of the water
(aquaplaning) . If this should occur, yo u
will have no warning from a s udden in ­
crease in engine speed as w ith a front­
wheel drive veh icle. Always drive at
speeds which are su ited to the road con­
ditions -risk of crash.

194 Driving and environment
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 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
max imum pe rm iss ible road or eng ine speed .
During and after break-in per iod
... Do not rev the eng ine up to h igh speeds
when it is cold. Th is app lies whether the
transmission is in N (Neutral) or in gear.
After the break- in period
... 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¢
page 10.
During the first few hours of driving, the en­
g ine's inter na l friction is higher tha n later
when alt the moving parts have been broken
i n. How welt this break- in process is done de­
pends to a conside rable extent on the way the
ve hicl e is driven du ring the first 1,000 miles
(1, 500 kilome ters).
(D Note
E xtremely high engi ne speeds are auto­
mat ica lly re duced. However, these rpm
lim its are programmed for a n engine welt
r u n- in, not a new eng ine.
{® 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
very carefully for the first 350 miles (500 kilo­ meters) after fitting.
_& WARNING
N ew tires tend to be slip pery a nd mus t al­
so be "broken -in" . Be s ure to remembe r
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.
Avoid damaging the
vehicle
When you a re d rivi ng on poo r roads, or over
cu rbs, ste ep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoile rs and ex ha ust
s ystem parts do not bot tom o ut and get dam ­
aged.
T his is espec ially true for veh icles with low­
s lu ng chassis (s por ts chassis)* and fully load­
ed vehicles.
Driving through water
on roads
Note th e following to avoid vehicle damage
whe n driving through water, for examp le on
flooded roads:
- The wa ter must not be any hig he r th an the
bottom of the vehicle body .
- Do not dr ive faste r than walk ing speed.

200 Trailer towing
Tire pressure
When towing a trai le r, inflate the tir es of your
vehicle 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 manufac ­
turers' specifications.
Lights
The headlight settings should be checked with
the trailer attached before dr iving off. Check
to make sure both vehicle and tra iler lights
are working properly.
Safety chains
Be sure trailer safe ty cha ins are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave eno ugh slack in the chains to per ­
mit turning corners. When you install safety
cha ins, make sure they w ill 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, p lease note the following:
.,. Do not tow a loaded trailer when your car it ­
self 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 re­
sults in a highly unstable distribution of
weight . If this cannot be avo ided, drive at very
low speeds only to avoid the risk of losing
steering control. A "ba
lanced'' 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 keep ing 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 veh icle while obse rving
tongue load requ irements and vehicle load ing
considerations.
Speed
The higher the speed, the more d iff icu 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 -pa rticularly
whe n going downhill.
Reduce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds
for vehicles tow ing trailers are lower than for
regular vehicles .
Always apply brakes early. When driving
downh ill, shift into a lower gear to use the en ­
gine braking effect to slow the vehicle . Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge c> page 10
must be observed carefully . If the needle
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light •
in the in strument cluster starts flashing, pull
off the road, stop and let the engine
idle for
abo ut two minutes to prevent heat build-up .
_& WARNING
Anyone not properly restrained in a mov­
in g vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not p roperly wea ring the restraints
provided by Audi.
