196 Smart Technology
- How far (if at all) the driver was depress ing
the accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can he lp provide a better under­
stand ing of the circumstances in which crash­
es and injuries occur. NOTE: EDR data are re­
corded by your vehicle only if a non-trivial
crash situation occ urs; no data are recorded by
the EDR under normal driving conditions and
no personal data (e.g., name, gender, age,
and crash location) are recorded. However,
other parties, such as law enforcement, could
comb ine the EDR data with the type of per ­
sonally identify ing data routine ly acquired
du ring a crash invest igation.
To read data recorded by an EDR, special
equipment is required, and access to the veh i­
cle or the EDR is needed . In add ition to the ve­
hicle manufactu rer, othe r parties, such as law
enforcement, that have the special equip­
men t, can read the information if they have
access to the vehicle or the EDR.
Some state laws restrict the retrieval or down­
loading of data stored by EDRs installed in a
vehicle for the express purpose of retrieving
data after an accident or crash event without
the owner's consent.
Aud i will not access the EDR and/or similar
data or give it to others -
- unless the veh icle owner (or lessee if the ve­
hicle has been leased) ag rees; or
- upon th e official request by the police; or
- upon the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the ju­
dicial discovery process.
- Audi may also use the data for research
about veh icle operation and safety perform­
ance or provide the data to a third party for
research purposes without identifying the
spec ific vehicle or information about the
identity of its owner or lessee and o nly after
the recorded vehicle data has been ac­
cessed.
Vehicle control modules
Your vehicle is also equipped with a number of
electronic control modules for various vehicle
systems, such as engine management, emis­
sion control, airbags, and safety belts.
T hese electronic control mod ules record data
during norma l vehicle operation that may be
needed by trained technicians for diagnostic
and repair purposes. The recording capability
of these modu les is limited to data (no sound
is recorded). Only a small amount of data is
actually recorded over a very limited period of
t ime, or stored when a system fault is detect­
ed by a contro l module . Some of the data
stored may relate to vehicle speed, direction,
or braking, as well as restraint system use and
performance in the event of a crash. Stored
data can also on ly be read and down loaded
with special eq uipment that is directly con­
nected to the vehicle .
(D Tips
Your vehicle may be equipped with Audi
connect. Your use of certain A udi connect
features requires wireless services that are
provided by a third party wire less telecom­
munications provider. For details regard­

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, 500 k ilome ters).
(D Note
Extremely h igh engine speeds a re auto­
ma tica lly reduced. However, t he se RPM

Driving and the environment 197
@) 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) . Bra ke 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 t o 150 miles (15 0 to
2 00 kilometers) o f no rma l cit y 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.

198 Driving and the environment
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water or mud, the
braking effect can be reduced due to mois­
ture on the brake discs and brake pads. A
few careful brake applications should dry off the brakes.
@) Note
Vehicle components such as the engine, transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Determ ine the depth before driving
through water.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water .
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid dr iving through salt water (corro­
s ion).
Catalytic converter
App lies to vehicles: with gasoline engine
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.
> Always use lead-free gaso line r=;, page 210,
Fuel supply .
> Never run the tank down all the way to emp-
ty.
> Never put too much motor o il in your engine
r=;, page 223, Adding engine oil > Never try to push- or tow -start your vehicle .
The catalytic converter is an efficient "clean ­
up" device built into the exhaust system of
the vehicle . The cata lytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critica lly
important for the life of the catalytic convert­
er and proper functioning of the engine.
A WARNING
-
The temperature of the exhaust system is high, both when driv ing and after stopping
the eng ine .
- Never touch the exhaust tail pipes once
they have become hot . This could result
in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additional undercoating or
rustproofing on or near the exhaust manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
r=;, page 223.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is moving.
- Do not continue to operate your vehicle
under these conditions, as otherwise fuel

200 Driving and the environment
Vehicles use the most fuel when they are ac­
celerati ng. If you anticipate what is going to
happen next, you will need to brake less and,
thus, accelerate less. let the vehicle coast
whenever poss ible -for example when you see
that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well be low your car's max imum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment. F ue l consumption, exhaust emissions and en ­
gine noise increase disproportionately at hig h
speeds . If you drive at approximately three
quarters of top speed, fue l consumption will
be reduced by one half. Never dr ive faster
tha n the posted speed limit and weather con­
d itions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
.. Sh ut the engine off when you are not dr iving
the vehicle.
.. Do not warm up the vehicle by letting the
engine run at idle.
It is efficient to switc h off the engine when
stopped at railroad crossings and long red
lights. Turning the engine off for just 30-40
seconds saves mo re fuel than is burned by
start ing the eng in e again.
It takes a long time for the engine to warm up
fu lly when it is running at idle. However, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
d rive away as soon as you sta rt the eng ine and
avoid ru nning a t high RPM wh ile the engine is
still warming up .
(D Note
Do not leave engine i dling unattended af­
ter start ing. If wa rning lights sho uld come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat , w hich could result in over­
hea ting o r othe r damage to the veh icle or
othe r property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
.. Have your ve hicle serviced at regu lar inter-
vals.
Having your veh icle regu larly serviced by an
authorized Aud i dealer helps to ensure that it
runs properly and econom ica lly. The cond it io n
of your veh icle not on ly affects its safety and
ability to ho ld its va lue, i t also affects
fuel
c onsumption .
Check your oil each t ime you fill your tank.
The amount of oi l used is re lated to engine
l oad and speed.
It is normal for the oil consump tion of a new
engine to reach its lowest value after a certain
mileage has been driven .
You m ust drive your ve hicle abou t 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion .
T his also ap plies to fue l consumption and en ­
gine o utp ut.
(D Note
- Have your veh icle ma inta in ed properly
and i n acco rdance with the service rec­
ommendations in you r W arranty
& Main­
t enance boo klet. l ack of proper ma inte ­
nance as well as im proper use of the ve­
hicle will impair the function of the
em iss ion cont ro l system and cou ld lead
to damage.

-Do not alter or remove any component of
the Emission Contro l System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, wh ich are designed to protect
your vehicle's Emission Control System and other important veh icle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
~ Try to avoid driving short distances with a
cold eng ine.
The engine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effectively.
Just after starting, a cold engine in a mid -size
car only achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2 .5 m iles (4 km),
the engine is at its proper operating tempera­
ture and fue l economy has reached a normal
l eve l. So you can see that you should avoid
short trips wheneve r possible.
The
outside temperature is also critical in this
regard . Your car consumes more fuel in the
winter than in the summer.

202 Trailer towing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, always fo llow the operating
and drivi ng i nstr uctions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and mu st be
mounted secure ly on the ve hicle's chassis at a
technically sound location . Use only a trailer
h itch with a removab le ball mount. A lways
check with the tr ailer hitch manu fac tur er to
make sure tha t you are using t he cor rect
hitch.
Do not us e a bumper hitch .
The hitch must be installed in such a way t hat
it does not interfe re with t he impact-absorb­
ing bumper syst em . No mod ifications should
be made to the vehi cle exhaust and brake sys ­
tems . From time to time, check th at a ll hit ch
mo unt ing bo lts remain secure ly fastened.
When you are not towing a trail er, remove the
tra iler hitch ba ll mount. This prevents the
hi tch from causing d amage sho uld your ve hi­
cle be str uck from be hind
¢ A .
Trailer brakes
If you r tra ile r is eq uipped w ith a braking sys­
tem, check to be su re that it conforms to a ll
r egulat ions . T
he trailer hyd raulic brake system mus t not be
direct ly connected to the vehicle's hydraulic
brake system .
Safety chains
Always use s afety chains be tween your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be
su re to c hec k w ith your Audi dea le r fo r cor rect
wiring, swi tches and relays.
Mirrors
If you are unable to see the traffic behind you
u sing the regular o utside m irrors, then you
must insta ll ext ended mirro rs . It is important
t h at you
always have clea r vis io n to the rea r.
,8. WARNING
-
Afte r removing t he trailer hit ch, d o no t
s tore it in yo ur vehicle . In case of sudden
br aking, t he h itch cou ld fly forward an d in­
j ur e you or yo ur passengers .
Operating instructions
Maximum traile r weight
A trai le r fo r you r vehicle is limited to a typi cal
class 1 or class 2 trai le r.
Trailer load distribution
B e sure the load in the t ra ile r is held secure ly
i n p lace to p reven t it from shift ing forw ard,
backw ard or sideways.
Never allow a passenger to ride in a trailer
¢ A in Driving instru ctions on page 203.
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is impo rtant that the cooling system 's
performance is up to the additional load .
Make su re that the coo ling system has enough
fl uid .
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to t he cold tire pressure listed under

M 1.1'1 ,....,
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open).
Inflate trailer t ires to tra iler and t ire manufac­
turers' specifications.
Lights
Check to make sure both vehicle 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 su re they wi ll not drag on the
road when you are driving.
The chains should cross under the tra ile r
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 poss ible handling of vehicle
and traile r, p lease note the following:
~ Do not tow a loaded tra iler 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 avoided, drive at very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con ­
trol. This means that the tow vehicle should be loaded to the extent poss ible and permiss i­
ble, wh ile keeping the trailer as light as poss i­
ble under the circumstances . Whenever possi-
Trailer towing 203
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tongue load requirements and vehicle load ing
considerations.
Speed
T he higher the speed, the mo re difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissib le speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill.
Reduce veh icle 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 trai lers are lower than for
regular vehicles .
Always apply brakes early. When driving
downhi ll, shift into a lower gear to use the en ­
gine braking effect to s low the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperatu re gauge <=> page 12
must be observed carefu lly. The coolant tem ­
perature can increase if you drive on long in­
clines 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.
For more information about indicator lights,
refer to .<=>
page 20.
A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi.

different weight distribution. Safety, perform ­
ance and economy wi ll greatly depend on how
carefu lly you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in a n area
away from traffic. Keep practicing until you
have become comp letely fam iliar with the way
your veh icle-trailer comb ination behaves and
responds.
Backing up is d iff icult and requires practice.
Backing up with a tra iler genera lly requires
steering action opposite to that when back ing
up your veh icle without a trailer.
Maintain a greater distance between your ve­
h icle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius.
When passing, remember that yo u cannot ac ­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow
p lenty of room for your tra iler before chang­
ing lanes aga in.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a tra iler dur ing the break-in
period of you r vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the ext ra load
¢ page 289.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol­
lowing:
Wh en park ing:
.. Apply the foot brake .
.. Have someone place chocks under both the
vehicle and the trailer wheels. ..
With chocks in place, slowly release the
brakes unti l the whee l chocks absorb the
load.
.. Turn the whee ls towards the curb.
.. App ly the parking brake.
.. Select the P selector lever posit ion.
When re starting afte r park ing :
.. App ly the foot brake.
.. Start the engine.
.. Select the D/S se lector lever position.
.. Release the parking brake and s lowly pull
out and away from the wheel chocks .
.. Stop and have someone retr ieve the wheel
chocks .
@ Tips
If you move the selector leve r of the auto­
matic transmission to P befo re applying
the pa rking brake and before bloc king the
whee ls, you may h ave to use more force
la ter to move the lever out of the P posi­
tion .
