& WARNING (continued )
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehi cle within a safe distance .
• Tires on a vehicle that has been overloaded can fail suddenly
c au sing lo ss of control and a cra sh.
• Always make sure that the total load being transported -
including the we ight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
v ehicle's Gross Vehicle Weight Rating .
& WARNING
• Incorrect tire pressures and /or underinflation can lead to a
serious or fatal accident.
• Incorre ct tire pressures and /or underinflation cause in creased
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,
c ausing loss of vehi cle control.

Checking tire pressure
The c orrect tire pressu re f or the tires ori gina lly installe d
on your vehicle is lis ted on the ti re pressure la bel loca ted
either on driver's side 8-pillar or inside the fuel filler flap.
The rec omme nded ti re p ressu res a re on the tire pr essure la be l an d
in the
table~ page 328, "Co ld tire inflation pressure". This means

not been driven for more than a couple of miles (kilometers) at low
speeds du rin g the p revio us th ree hou rs . Ai r in t he tires ex pand s
when the tire heats up as a resu lt of internal fr iction as it flexes in
use. The tire pressure is hig her when the tire has warmed up than
when it is "co ld ." I
t is the inflation pressure in a "cold" t ire that counts . Therefore, you
s h oul d never le t air ou t of a warm ti re to matc h "Co ld t ire in fl ati on
pressure"
recommendations~ pa ge 328 . The tires wou ld then be
u nde rinflate d and could fail sud denly .
The t ire pressure label o n your Au di lists the recomme nded cold t ire
inflation press ures at maximum capacity for the new, origina l equip ­
m ent tires t hat we re on yo ur vehicle at t he t ime it was manufac ­
tured. For the location of the

you drive ov er a pothole or h it a curb while parkin g. It is usually not
pos sible to see whe the r the rad ial tir es use d today are unde rin flated
just by look in g at t hem .
T herefore, be sure to chec k tire pressures at least once a month and
a lways be fore go ing o n a lo ng trip . Make su re to take the nu mber o f
people and the amount of luggage into account when ad justing tire
pr ess u re fo r a trip -even one t hat you wou ld not conside r to be

See~ page 333, "Tires and vehic le load limits" for more
i mp ort ant i nfor mati on .
A lways use a n accu rate ti re p ressure gauge w hen c hec kin g a nd
adjusting inflation pressures . Chec k all of the tires and be sure not
t o fo rget t he spare t ire . If the pressu re i n an y tire is too high when
the tire is "co ld," let air out of the tire slow ly with the edge of the tire
ga uge and kee p checking the press ure u ntil y ou r each th e pr essu re
that is correct for the load (passengers and luggage) and kind of
d riv in g yo u plan to do .
I f 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
t hat you need to r each the correct pressure for the veh ic le load
(passengers and luggage) for the tires on your vehicle as listed on
t he o n you r vehicl e and i n thi s m anua l a n d t he kind of driving yo u
p lan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason .
Remember that the vehic le manufacturer, not the tire manufacturer,
deter mines the correc t tire pressure for the ti res on your vehicle.

After changing a wheel
A wheel change is not complete without the doing the
following.
-Store and secure the wheel you replaced in the spare
wheel well.
-Replace the tools and the jack in their proper location.
-Check the tire pressure on the spare wheel immediately
after mounting it.
-As soon as possible , have the tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 90 ft lb (120 Nm) .
-Have the flat tire replaced as soon as possible.
[ i] Tips
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque . .,_
