- The brakes on a vehicle t hat has been
overloaded may not be able to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload-
ed can fail suddenly causing loss of con-
trol and a crash.
- Always make sure that the tota l load be-
ing transported - including the we ight of
a tra iler hitch and the tongue weight of a
loaded trailer - does not make the veh i-
cle heavier than the vehicle's Gross Vehi-
cle Weight Rating.
A
WARNING
- Incorrect tire pressures and/or underin-
fla t ion can lead to a serious or fatal acci-
dent.
- Incorrect t ire pressures and/or underin-
fla t ion cause increased tire wear and can
affect t he handling of the vehicle .
- Incorrect t ire pressures and/or underin-
flation can also lead to sudden tire fa il-
ure, incl uding a blowo ut and sudden de-
flation, causing loss of vehicle control.
Checking tire pressure
.
The correct tire pressure for the tires original-
ly installed on your vehicle is listed on the tire
pressure Lobel located on driver's side 8-pil-
lor.
The recommended t ire pressures are on t he
tire pressure label and in the tab le
c=>
page 235, Cold tire inflation pressure. This
means that the pressure must be checked and
adj usted when the tire has not been driven for
more than a couple of m iles (kilometers) at
low speeds during the previous three hours .
Air in the tires expands when t he tire heats up
as a result of inte rnal fr iction as it flexes in
use. The t ire pressure is higher w hen the tire
has wa rmed up th an when it is "cold."
It is the inflat ion pressure in a "cold" tire that
counts. Therefore, you shou ld never let air out
of a warm t ire to matc h "Cold tire infl ation
pressure" recommend ations

ti res wo uld t hen be unde rinflated and could
fail suddenly.
The ti re pressure label on your Aud i list s t he
recommended cold t ire inflation pressures at
maximum capacity f or the new, orig inal
equipment tires that were on your vehicle at
the time it was manufactured. For the loca-
tion of the label

Most tires lose air naturally over t ime. They
can also lose some air if you drive over a pot-
hole or hit a curb while par king. It is usually
not possible to see whether the rad ial tires
used today are underinflated just by looking
at them .
Theref ore, be sure to check t ire pressures at
least once a month and always before going
on a long tr ip. Make sure to take the number
of people and the amount of luggage into ac-
count when adjust ing tire pressure for a tr ip -
even one that you wou ld not conside r to be
"long." See
c::>
page 239, Tires and vehicle
food limits
f or mo re import ant inform ation .
Always use an accurate ti re pressure gauge
when checking and adju sting inflation pres-
sures. Check all of t he tires and be sure not to
forge t the spare tire.
If
t he pressure in any t ire
is too high when t he ti re is "cold", let air out
of the ti re slow ly 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
driv ing you plan to do.
If the pressure in any ti re 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 you r veh icle as listed on the on
you r vehicle and in this ma nual and the kind
of drivi ng you plan to do .
Never exceed th e maximum inflation pres-
sure listed on the tire sidewall for any rea-
son.
