WARNING
(continued)
•
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.
•
Checking
tire
pressure
The
correct
tire
pressure for the tires originally installed
on your vehicle is listed on the tire
pressure
label located
on
driver's side 8-pillar.
The recommended
tire
pressures are on
the
tire pressure
label
and
in the table
=>
page
240,
"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 miles (kilometers) at
low
speeds during the previous
three
hours. Air in
the tires
expands
when the tire heats up as a result of internal friction as 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
=>
page
240.
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 new, original equipment tires that were
on your vehicle at the time
it
was manufactured
.
For
the location of
the label
=>
page
240,
fig.
149.
Most
tires
lose
air naturally over time. They can also lose some air
if
you drive over a pothole or hit a curb while parking. It is usually not
possible
to see whether
the
radial tires used today are underinflated
just by looking at them.
Therefore,
be sure to check tire pressures at
least
once a month and
always before going
on
a
long
trip.
Make
sure to take
the
number of
people and the amount of luggage into account when adjusting tire
pressure for a trip
-
even one
that
you would not consider to be
"long." See=> page
244,
"Tires and vehicle load limits" for more
important information.
Always use an accurate tire pressure gauge when checking and
adjusting inflation pressures
.
Check
all of the tires and be sure not
to forget the
spare tire. If the
pressure
in any tire
is
too
high
when
the tire is "cold," let air out of the tire slowly with the edge of the tire
gauge and keep
checking the pressure
until
you reach the pressure
that is correct for the load (passengers and luggage) and kind of
driving you plan
to
do.
If
the pressure
in
any tire
is
too low, note the
difference
between the
pressure in the cold tire and the pressure you need and add the air
that you need
to
reach the correct pressure
for the
vehicle load
(passengers and
luggage)
for the tires on your vehicle as
listed
on
the
on your vehicle and in
this manual
and
the kind of driving
you
plan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember
that the vehicle manufacturer, not the tire manufacturer,
determines
the
correct
tire pressure for the
tires on your vehicle.
It
is important to check the tire pressure when the tires are cold.
•
Read the required tire pressure from the tire pressure label
located
on driver's side
8-pillar.
•
Turn the valve
stem
cap counter -clockwise
to remove
it from
the
tire
valve.
•
Place the
air
pressure
gauge on the valve.
•
The
tire pressures should only be checked and adjusted when
the
tires
are cold. The slightly 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.
