• Do not reuse batteries which were frozen . The battery housing
may have cracked and weakened when the battery froze .
• Charge the battery in a well ventilated area . Keep away from
open flame or electrical spark . Do not smoke . Hydrogen gas gener ­
ated by the battery is explosive .
• To reduce the danger of explosion , never connect or disconnect
charger cables wh ile the charger is operating .
• Fast charging a battery is dangerous and should only be
attempted by a competent technician with the proper equipment .
• Battery acid that may spill during charging should be washed
off with a solution of warm water and baking soda to neutralize
the acid .
0 Note
• Nev e r use a fast charger as a booster to start the engine. This will
seriously damage sensitive electronic components, such as control
units, re lays, radio, etc ., as wel l as the battery charger .
• T he vehicle may be optio nally equi ppe d wi th a ge l batt ery , w hich

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, particu larly considering the comparatively small patch
of rubber on each tire that assures that all -important contact
between you, your vehic le 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 regularly inspecting tires for damage inc luding cuts, s lashes 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
blowouts.
A vo iding d am age
If you have to drive over a curb or similar obstac le, drive very slowly
and as close as possible at a right angle to the curb.
A lways keep chemica ls including grease, oi l, gaso line and brake
fluid off the tires.
Inspect the ti res regu larly for damage (cuts, cracks or b listers, etc.l .
Remove any foreign bodies embedded in the treads.
Storing tir es
Mark tires when you remove them to indicate the direction of rota ­
t ion. This ensures you to be able 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.
S tore tires in a vertical pos it ion if they a re not mounted on r ims, in
a horizonta l position if they are mounted on rims.
New tir es
New tires have to be broken in=>&.
The tread depth of new ti res may vary, according to the type and
make of tire and the tread pattern.
H idd en damage
Damage to tires and rims is often not readily visible. If you notice
unusual vibration or the vehicle pu lls to one s ide, this may indicate
that one of the tires has been damaged . The tires must be checked
immediately by an authorized Audi dealer or qualified workshop .
Unidire cti ona l t ires
A unidirectional tire can be identif ied by arrows on the sidewa ll, that
point in the direction the tire is designed to rotate . You must fo llow
t he specified directio n of rotation . This is necessary s o that these
tires can develop their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance . For more information

U ni form Tire Q ua lity G rading
is a tire information system developed by the United States Nationa l
Highway Traffic Safety Administration (N HTSA) that is designed to
help buyers make re lative comparisons among tires. The UTQG is
not a safety rating and not a guarantee that a tire will last for a
prescribed number of miles or perform in a certain way. It simply
gives tire buyers additiona l information to combine with other
considerations, such as price, brand loya lty and dealer recommen- dations
. Under UTQG, tires are graded by the tire manufacturers in
three areas : treadwea r, trac tion and temperature resistance. The
U TQG information on the tires, molded into the sidewalls.
U .S . DOT Tire Identifi cation Number (TIN )
This is the tire's "serial number" It begins with the letters "DOT" and
indicates that the ti re meets a ll federa l standards. The next two
numbers or letters indicate the plant where it was manufactured,
and the last four num bers represent the week a nd 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
t he tire manufacturer. This information is used to contact
consumers if a tire defect requires a recall.
Vehicle capa cit y weight
means the rated cargo and luggage load plus 150 lbs. (68 kilograms)

Cold tire inflation pressure
Tire
pressure affects the overall handling, performance and safety of a vehicle.

label: located either on
driver's side B-pillar or
inside the fuel filler flap
Tire pressure generally refers to the amount of air in a tir e that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents. Tire pressure is measured in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSI). 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.

Maintaining proper tire pressure is one of the most important
th ings 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 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
