with great force and will smash the child
safety seat and child against the backrest,
door or roof. Have the airbag system in­
spected immediately by your Audi dealer.
- Improper installation of child restraints can
reduce their effectiveness or even prevent
them from providing any protection .
- An improperly installed child restraint can
interfere with the airbag as it deploys and
seriously injure or even kill the child.
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier .
- Never place additional items on the seat
that can increase the total weight registered
by the weight-sensing mat and can cause in­
jury in a crash.
A WARNING
Forward-facing child restraints:
-Always make sure the forward-facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Never put the forward-facing child restraint
up, against or very near the instrument pan­
el.
-Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible before installing the for­
ward-facing child restraint. The backrest must be adjusted to an upright position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
A WARNING
Rearward-facing child restraints:
- A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates - even with an Ad­
vanced Airbag System .
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
Child Safety
will smash the child safety seat and child
against the backrest, door or roof.
- Always be especially careful if you must in­
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir­
cumstances.
- A tight tether strap on a rearward-facing
child restraint attached to the front passen­
ger seat can put too much pressure on the
weight -mat in the seat and register a heavi­
er weight in the Advanced Airbag System .
The heavier weight registered can make the
system work as though an adult were on the
seat and deploy the Advanced Airbag when
it must be suppressed causing serious or
even fatal injury to the child.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
- Never install a rearward facing child safety
seat on the front passenger seat unless the
PASSENGER AIR BAG OFF light comes on
and stays on. If the
PASSENGER AIR BAG
OFF
light does not come on and stay on
have the airbag system inspected immedi­
ately by your Audi dealer .
Activating the convertible locking retractor
Use the conver tible locking re trac tor to secure a
child restraint.
Always h eed the child safety seat manufacturer's
instructions when installing a child restraint in
your vehicle. To ac tiva te the convertible locking
retractor:
.. Place the child restraint on a seat.
.. Slowly pull the belt
all the way out .
.. Route it around or through the child restraint
belt path
c:> ,&. .
.. Push the child safety seat down with your full
weight to get the safety belt really tight.
.,. Insert the belt tongue into the buckle for that
seating position.
.. Guide the safety belt back into the retractor un­
til the belt lies flat and snug on the child safety
seat. ..,.

General notes
Tires may be the least appreciat­
ed and most abused parts of a
motor vehicle.
Tires may be the least appreciated
and most abused parts of a motor
veh ic le . Tires are, however, one of
the most important parts of ave ­
hicle, particularly considering the
comparatively small patch of rub­
ber on each tire that assu res that
all-important contact between
you, your vehicle and the road .
Maintain ing the correct t ire pres­
sure, making sure that your vehi­
c le and its tires do not have to
carry more weight than they can
safe ly handle, avoiding damage
from road hazards and regularly inspecting tires for damage in­
c luding cuts, slashes i rregular
wear and overall condition are the most important th ings that you
can do to help avo id sudden tire
failure including tread separation
and blowouts.
Avoiding damage
~ If you have to dr ive over a curb or ":
~ similar obstacle, drive very s lowly

Tir es a nd whe els
and as close as possible at a right
ang le to the curb.
Always keep chemicals including
grease, oil, gasoline and brake
fluid off the tires. Inspect the tires regularly fo r
damage (cuts, cracks or blisters ,
etc.) . Remove any foreign bodies
embedded in the treads.
Storing tires
Mark tires when you remove them
to indicate the direction of rota­
tion. This ensures you to be able
to mount them correctly when
you reinstall them.
When removed, the w heels or
tires sho uld be stored in a coo l,
dry and preferably dark place.
Store tires in a vertical position if
they are not mounted on rims, in
a horizon tal position if they are
mounted on rims .
New tires
New tires have to be broken in
¢,&.
The tread depth of new tires may
vary, according to the type and make of tire and the tread pa t­
tern.

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of
a vehicle.
Fig . 147 Tire pressure label: located on
driver's side 8-pillar
Tire 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.
Tire pressure is measured in kilo­
pascals (kPa), the international
measuring unit and in pounds per
square inch (PSI). Tire pressure is
based in part on the vehicle's de­
sign and load limit -the greatest
amount of weight that the vehicle
can carry safely and the tire size.
The proper tire pressure is fre-

Fig. 148 Tire pressure label
quently referred to as the "recom­
mended cold tire inflation pres­
sure." 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 infla-
tion pressure in a "cold" tire that
counts. Therefore , you should
never let air out of a warm tire to
match "cold tire inflation pres­
sure" recommendations. The tires ""

...
would then be underinflated a nd
could fail suddenly .
M ainta ining proper tire pressure
is one of the most important
things you can do to he lp avoid
s u dden tire fai lure . Under inflated
tires are a major cause of sudden
tire fa ilure . Keeping tires at the
r ight pressure is also important
for safe and responsive vehic le
handling, traction, braking and
load carrying.
Tire pressures are
particularly important when the
vehicle is be ing dr iven at higher
speeds, and then especially when
heavily loaded even within the
permissib le load-carrying capaci­
ties 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
transport ing .
The tire pressure label is located
on the driver's side 8-pillar . The
tire pressure label lists the recom­ mended cold tire inflation pres­
s u res for the vehicle at its maxi­
mum capacity weight and tires

If you wish to improve comfort
when operating the vehicle at
normal load (up to 2 occupants ),
you can adjust tire pressu res to
those specified for normal vehi­
cle load . Before operating the ve­
hicle at ma ximum load, you
must increa se the ti re pressures
to those specified for maximum
vehic le load

Bear in mind that the tire pres­
sure monitoring system can only monitor the tire pressures that
are stored. The system does not recognize the load condition of
your vehicle .

Because technical changes may be
made to vehicle equipment dur­
ing the model year, always com­
pare the tire size designation on
the tire pressure label on your ve­ hicle with the tires on your vehi­
cle. Make sure that the tire size information on the vehicle label is
the same as the size of the tires on the vehicle. This is especially
important if the vehicle belongs
to someone else or you bought
the vehicle with different rims/
tires or you bought the vehicle as a previously owned vehicle.
Remember, your safety and that
of your passengers also depends
on making sure that load limits
are not exceeded. Vehicle load in­
cludes everybody and everything
178
in and on the vehicle. These load
limits are technically referred to
as the vehicle's Gross Vehicle
Weight Rating ("GVWR"). The
Gross Axle Weight Rating ("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles. The Gross Ve­ hicle Weight Rating and the Gross
Axle Weight Rating are listed on
the safety compliance sticker la­ bel located on the driver's side B­
pillar. The tire pressure label on
your Audi lists the maximum combined weight of all of the oc­
cupants and luggage or other car­
go that the vehicle can carry. For

.&_ 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.

Audi lists the recommended cold
tire inflation pressures for the
