-Never try to push- or tow-start your vehic le .
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 po llutants in the exhaust gas before they are released into the
atmosphere.
The exclusive use of un leaded fuel is critica lly important for the life
of the catalytic converter and proper functioning of the engine .
& WARNING
• Do not par k or operat e the vehicle in areas w here the ho t

0 Note
• Be aware that just one tank filling with le aded fue l wil l a lready
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level
~ page 275.
• Do not drive until the fuel tank becomes completely empty. The
engine could misf ire. Unburned fuel could also get into the exhaust
system and this could cause the catalytic converter to overheat.
• Do not turn off the ignit ion whi le the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the cata lytic converter. This could result
in overheating of the converter, requiring its rep lacement .

ving and environm ent
• To assure efficient operation of the Emission Control System:
- Have your vehic le maintained properly and i n accordance w ith
the service recommendations in your Warranty
& Maintenance
booklet .
- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the function of the em ission control system
and could lead to damage .
Even when the Emission Control System is operating properly, the
exhaust gas can have a sulfur-like exhaust gas smell under some
operating states . This depends on the su lfur content of the fuel
bei ng used. Using a different brand of fue l may help, or fil ling the
tank with lead-free super grade gasoline .
Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels .
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your persona l driving style
• operating conditions
• technica l limitations
If you anticipate what you need to do next and drive economica lly,
you can easily cut your fuel consumpt ion by 10-15 percent . This
section wil l give you some tips on how you can help the environ-
ment and your pocketbook . ...

Trailer load d is trib ut ion
Be sure the load in the trailer is held securely in place to prevent it
from shifting forward, backward or sideways.
Ne ver allo w a passen ger to rid e i n a tr ailer => & in "Driving instruc ­
tions" on
page 249.
En gin e c ool ing syst em
Towing a trailer makes the engine work harder. It is important that
the cooling system 's performance is up to the additiona l load. Make
sure that the cooling system has enough flu id.
Ti re press ure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the labe l located either on the
driver's side B-pillar (visible when the door is open} or inside the fuel
filler flap . Inflate trailer tires to trai ler and tire manufacturers' spec ­
ifications.
Ligh ts
The headlight settings should be checked with the trailer attached
before driving off . Check to make sure both vehicle and trailer lights
are working properly .
Safe ty c hain s
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave enough slack in the chains to
permit turning corners. When you install safety chains, make sure
they will 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 separation from the hitch.

Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of veh icle and trailer,
please note t he following :
Do not tow a loaded trailer when your car itself is not
loaded .
- Be especia lly careful when passing other vehicles .
Observe speed l imits .
Do not drive at the maximum permissible speed.
Always apply brakes early.
Monitor the temperature gauge.
W eight distrib utio n
Towing a loaded trailer with an empty car results in a h ighly
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 control. This means that
t he tow vehicle should be loaded to the extent possible and permis ­
sible, while keeping the trailer as light as possib le under the circum ­
stances . Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considerations.
S pee d
The higher the speed, the more difficu lt it becomes for the d river to
control the rig. Do not drive at the maximum permissible speed.
Reduce your speed even more if load, weather or wind conditions
are unfavorable -particularly when going downhill .
Reduce vehicle speed
i mmed iatel y if the trailer shows the slightest
sign of swaying .
Do not try to st op the swa ying b y accelerating.

Tires
General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particularly considering the comparative ly sma ll patch
of rubber on each tire that assures that all- important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regu lar ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overa ll condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avoiding dama ge
If you have to drive over a curb or similar obstacle, drive very slow ly
and as close as possible at a right angle to the curb.
A lways keep chemica ls includ ing grease, oil, gasoline and brake
f luid off the tires.
I nspec t the tires regularly for damage (cuts, cracks or blis ters, etc.l.
Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove them to indicate the direction of rota ­
tion . This ensu res you to be ab le to mount them correctly when you
reinstal l them. When removed, the wheels or tires shou
ld be stored in a coo l, dry
and preferably dark place.
St ore t ires in a vertical posit ion if they a re not mounted on rims, in
a horizontal position if they are mounted on rims.
New tire s
New tires have to be broken in~&.
The tread dep th of new tires may va ry, according to the type and
make of tire and the tread pattern.
Hidden d ama ge
Damage to tires and rims is often not readily visible. If you notice
unusua l vibration or the vehicle pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immed iately by an authorized Audi dealer or qualified workshop .
Unidire ction al tir es
A unidirectio nal tire can be iden tif ied by arrows on the s idewa ll, that
point in the direction the tire is designed to rotate. You must follow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information

& WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­

Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead
means the part of the tire that is made of steel wires, wrapped or reinforced by ply cords and that is shaped to fit the rim.

& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted.
Curb weight means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire design to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire. Extra load tires
may be identified as "XL",

Uniform Tire Quality Grading
is a tire information system developed by the United States National
Highway Traffic Safety Adm inistration (NHTSA) that is designed to
help buyers make relative comparisons among tires. The UTQG is
not a safety rati ng and not a guarantee that a tire will last for a
prescribed number of miles (kilometers) or perform in a certain way.
It simply gives tire buyers additional informat ion to combine with
other considerations, such as price, brand loyalty and dealer recom-mendations. Under UTQG, tires are graded by the tire manufac­
t urers in three areas: treadwear, traction, and temperature resis­
tance . The UTQG information on the tires, molded into the
sidewalls.
U .S. DOT Tire Identification Number (TIN }
This is the tire's "seria l number". It begins with the letters "DOT"
and indicates that the tire meets al l federa l standards. The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac­
ture. For example,
DOT ... 2209 ...
means that the tire was produced in the 22nd week of 2009 . The
other numbers are marketing codes that may or may not be used by
the tire manufacturer . This information is used to contact
consumers if a tire defect requires a reca ll.
Vehicle capacity weight
means the rated cargo and luggage load plus 150 lbs. (68 kilograms)
times the vehicle's tota l seating capacity as listed on the label
located either on the driver's side 8-pillar or on the inside of the fuel

Vehicle maximum load on the tire
means that load on an individual tire that is determined by distrib­
uting to each axle its share of the maximum loaded vehicle weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual tire that is determined by distrib­
uting to each axle its share of the curb weight, accessory weight,
and normal occupant weight (distributed in accordance with table
below =>
page 291) and dividing by two. _..

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 229 Tire pressure
label: located either on
driver's side B-pillar or
inside the fuel filler flap
Tir e pressure generally refers to the amount of air in a tire that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents. T ire pressure is measured in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSll. Tire pressure is based in part on the vehicle's design and
load limit -the greatest amount of weight that the vehicle can carry
safely and the tire size . The proper tire pressure is frequently
referred to as the "recommended cold tire inflation pressure." Air in
the tires expands when the tire heats up because of internal friction
when it flexes in use. The tire pressure is higher when the tire has
warmed up than when it is "cold." It is the inflation pressure in a
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure" recommendations.
The tires would then be underinflated and could fail suddenly.

Main taining proper tire pressure is one of the most important
things you can do to help avoid sudden tire failure. Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying.
Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load-carrying capacities approved for your vehicle.
The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
On USA vehicles, the tire pressure label is located on the driver's
side B-pillar. On Canada vehicles, the tire pressure label is located
either on the driver's side B-pillar or inside the fuel filler flap . The tire
pressure label lists the recommended cold tire inflation pressures ..,.

If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants) , you can adjust tire pressures to
those specified for normal vehicle load. Before operating the vehicle at maximum load, you must increase the tire pres sures to those
