charger),
the battery cables do not have to be
disconnected first. Before charging at
high vol­
tages, i .e.
"fast charging", you must disconnect
both cables. In either case , follow the instruc­
tions from the manufacturer of the charger.
Fastcharging a battery is
dangerous¢.&. in
Working on the battery on page 166.
It requires
special charging equipment and the knowledge
to go with it. We recommend having your battery
fast charged only by a qualified workshop.
A discharged battery can
freeze at temperatures
of only 32
°F (0 °C). Allow a frozen battery to ..,.

Checking and filling
thaw completely before attempting to charge it
c> &. . However, we recommend not us ing a
thawed battery again because the battery casing
can be cracked due to ice format ion and can leak
battery acid.
Do no t open the battery caps when charging the
battery .
A WARNING
Charging a battery can be dangerous.
- Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice. Al­
low a frozen battery to thaw out first.
- Do not reuse batteries which were frozen.
The battery housing may have cracked and
weakened when the battery froze.
- Charge the battery in a we ll ventilated area.
Keep away from open flame or electrical
spark. Do not smoke . Hydrogen gas generat­
ed by the battery is explosive .
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating .
- Fast charg ing a battery is dangerous and
should only be attempted by a competent
technician with the proper equipment .
- Battery acid that may spill during charg ing
sho uld be washed off w ith a solution of
warm water and baking soda to neutralize
the acid.
CD Note
Never use a fast charger as a booster to start
the engine. This will seriously damage sensi­
tive electronic components, such as control
units, re lays, radio, etc., as well as the batte ry
charger.
@ Tips
- The vehicle battery must not be charged
with a standard small charger that plugs in­
to the cigarette lighter or outl et.

Tires and wheels
Hidden damage
Damage to tires and rims is often
not readily visible. If you notice
unusual vibration or the vehicle
pulls to one side, this may indi­
cate that one of the tires has been
damaged. The tires must be
checked immediately by an au­
thorized Audi dealer or qualified
workshop.
Unidirectional tires
A unidirectional tire can be identi­
fied by arrows on the sidewall,
that point in the direction the tire
is designed to rotate. You must
follow the specified direction of
rotation . This is necessary so that
these tires can develop their opti­
mum characteristics regarding
grip, road noise, wear and hydro­
planing resistance. For more in­
formation
¢ page 203 .
A WARNING ~ -
New tires or tires that are old,
worn or damaged cannot pro­
vide maximum control and
braking ability.
-New tires tend to be slippery
and must be broken in. To re­
duce the risk of losing control,
a collision and serious person­
al injuries, drive with special
170
care for the first 350 miles (560 km).
-Driving with worn or damaged tires can lead to loss of con­
trol, sudden tire failure, in­
cluding a blowout and sudden
deflation, crashes and serious
personal injuries. Have worn
or damaged tires replaced im­
mediately.
-Tires age even if they are not being used and can fail sud­
denly, 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.
-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.

.&_ WARNING
Overloading a vehicle can cause loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death .
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and in­ crease the risk of a loss of ve ­
hicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud­
denly causing loss of control
and a crash.
A WARNING
-
- Incorrect tire pressures and/or
underinflation can lead to a
serious or fatal accident.
-Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the
handling of the vehicle.
- Incorrect tire pressures and/or
underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
Tires and wheels
Checking tire pressure
The correct tire pressure for the
tires originally installed on your
vehicle is listed on the tire pres­
sure label located on driver 's side
8-pillar .
The recommended tire pressures
are on the tire pressure label and
in the table
c:::> page 176 , Cold tire
inflation pressure.
This means
that the pressure must be checked and adjusted when the
tire has not been driven for more
than a couple of m iles (kilome­
ters) at low speeds during the
previous three hours. Air in the
tires expands when the t ire heats
up as a result of internal friction
as it flexes in use . The tire pres­
sure 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 shou ld never let air out of a
warm tire to match "Cold tire in­
flation pressure" recommenda ­
tions
c:::> page 176. The tires would
then be underinflated and could
fail suddenly.
The tire pressure label on your
Audi lists the recommended cold
tire inflation pressures for the

" N ": ... IO "? N U'> .....
-Place the air pressure gauge on the valve .
- The tire pressu res should only be
checked an d adjusted when the
t ires are cold. The slig htly raised
pressures of warm tires must
not be reduced .
- Adjust the tire pressure to the
load you are carrying.
-Reinstall the valve stem cap on the valve .
When should I check the tire
pressu re?
The correct tire pressure is espe­
cially important at high speeds .
The pressure should therefore be
checked at least once a month
and always before starting a jour­
ney.
When should I adjust the tire pressures ?
Adjust the tire pressure to the
load you are carrying . After
changing a wheel
or replacing
wheels you have to adjust the tire pressures on all wheels. In addi ­
tion, you must then initialize the
new tire pressures in the tire pres­
sure mon itoring system

A WARNING
Incorrect tire pressures and/or
underinflation can lead sudden
tire failure, loss of control, col­ lision, serio us personal injury or
even death .
-When the warning symbol
rD]
appears in the instrument
cluster, stop and inspect the
tires.
- Incorrect tire pressure and/or
underinflation can cause in­
creased tire wear and can af ­
fect the handling of the vehi­
cle and stopping ab ility.
- Incorrect tire pressures and/or
underinflation can also lead to
sudden tire failure, including a
blowout and sudden deflation,
causing loss of vehicle control.
- The driver is responsib le for
the correct tire pressures for
all t ires on the vehicle . The ap ­
plicable pressure values are lo­
cated on a sticker on the driv ­
er's side B-pillar.
-Only when all tires on the ve­ hicle are filled to the correct
pressure, the tire pressure monitoring system can work
correct ly .

technically referred to as the vehi­
cle's
Gross Vehicle We ight Rating
("GVWR") .
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci ­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar. Your Audi
has 2 seating positions . Each
seating position has a safety belt
¢ page 95, Safety belts.
The fact that there is an upper
limit to your vehicle's Gross Vehi ­
cle Weight Rating means that the
total weight of whatever is being
Tires and wheels
carried in the vehicle is limited.
The more passengers in the vehi­
cle or passengers who are heavier
than the standard weights as­
sumed mean that less weight can
be carried as luggage.
The tire pressure label on your
Audi also lists the maximum com ­
bined weight of all of the occu­
pants and luggage or other cargo
that the vehicle can carry. For the location of the label¢

A WARNING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and in­
crease the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not be able to stop the vehicle
within a safe distance .

Tires and wheels
All-wheel drive
Only the wheel/tire sizes specified
by the manufacturer may be used
on vehicles with all-wheel drive. For details see¢
page 139.
A WARNING
Sudden tire failure can lead to
loss of control, a crash and seri­
ous 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 sud­
denly, 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.
New tires and replacing tires
