- Read the engine coolant level in the open coolant expan­
sion tank :::::>
page 338, fig. 287. With a cold engine, the
coolant level should be between the "min" and "max"
markings. When the engine is warm, the level may be
slightly above the "max" marking.
The location of the coolant expansion tank can be seen in the
engine compartment illustration~
page 332.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped with an electric
coolant level sensor.
When the coolant level is too low, the warning light in the Auto­
Check System~
page 33will blink until you add coolant and the
level has been restored to normal. Even though there is an electric
coolant level sensor, we still recommend you check the coolant level
from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling system . In the event
of coolant loss, the cooling system should be inspected immedi­
ately by your authorized Audi dealer . It is not enough merely to add
coolant.
In a
sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating.
& WARNING
The cooling system is under pressure and can get very hot. Reduce
the risk of scalding from hot coolant by following these steps.
• Turn off the engine and allow it to cool down.
• Protect your face, hands and arms from escaping fluid and
steam by covering the cap with a large, thick rag.
& WARNING (continued)
• Turn the cap slowly and very carefully in a counter-clockwise
direction while applying light, downward pressure on the top of
the cap .
• To avoid being burned, do not spill antifreeze or coolant on the
exhaust system or hot engine parts. Under certain conditions, the
ethylene glycol in engine coolant can catch fire.
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coolant. Adding radiator repair fluid may adversely affect the func ­
tion and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty. •
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compartment,
always read and heed all WARNINGS:::::> & in "Working in
the engine compartment" on
page 331.
- Turn off the engine.
Let the engine cool down.
Place a thick rag over the coolant expansion tank
=:> page 338, fig. 287 and carefully twist the cap counter­
clockwise :::::>& .
Add coolant.
- Twist the cap on again
tightly.
Replacement engine coolant must conform to exact specifications
~ page 337, "Coolant". Even in an emergency, if coolant additive .,,

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
~ page 379.

& 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
ment (whether installed or not).
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.
Bead separation means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
& 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",
"xi", "EXTRA LOAD", or "RF" on the side ­
wall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire -ground interfaces.
Gross Vehicle Weight Rating ("GVWR"l
means the maximum total loaded weight of the vehicle.

& WARNING (continu ed )
• Incorrect tire pressure and /or under inflation can cause
in creased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect t ire pressures and /o r underinflat ion can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing lo ss of vehicle control .
• The driver is respon sible for the correct tire pressures for all
tires on the vehicle. The applicable pre ssure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
• Only when all tires on the vehicle are filled to the correct pres ­
sure , the tire pressure monitoring sy stem can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is essential that the driver observe
the specified tire pressure value s for the tires and the correct pres ­
sures for the function of the tire pressure monitoring system.
• Always inflate tires to the re commended and correct tire pres ­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation , sudden tire failure and loss
of control.
• Ex cessive speed and /overloading can cause heat build-up ,
s udden tire failure and lo ss of control .
• If the tire pres sure is too low or too high , the t ires will wear
prematurely and the vehicle will not handle well .
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service station
to check the t ire pressure and add air as required.

make, there will be six to eight of them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other symbols)
indicate the positions of the tread wear indicators. Worn tires must
be replaced. Different figures may apply in other countries=>& .
Tire pressure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out. For this reason, tire pressure must be checked
at least once a month =>
page 353.
Driving style
Driving fast around curves, heavy acceleration and hard braking
increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rotated according to the
tire manufacturer's suggested tire rotation intervals. Please
remember the following:
• Tire rotation intervals may differ from the vehicle service inter­
vals outlined in your Warranty
& Maintenance booklet.
• The longer one tire is used in one location on the vehicle , the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer's suggested tire rotation intervals .
• Vehicles with front-wheel drive experience more tread wear on
the front wheels compared to all-wheel drive (quattro ®l.
• Please rotate tires as shown =>
page 357, fig. 294.
• Extra care must be taken when rotating direction-specific tires
=>
page 379.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday driving can cause them to become unbal ­
anced, resulting in vibrations you can usually feel through the
steering wheel. Unbalanced
wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause excessive tire wear , impairing
the safety of the vehicle. If tires show excessive wear, have the
wheel alignment checked by an authorized Audi dealer or qualified
workshop.
All Wheel Drive
Vehicles with quattro® must always have tires of the same size,
construction and tread type. For details see=>
page 294.
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage, such as
grease, oil, gasoline and brake fluid away from tires .
• 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
lower speeds .
• 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. •
