2012 AUDI A8 control arm

vehicle from handling properly and in­crease the risk of a loss of veh icle con­
tro l.
- The brakes on a veh icle that 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
tro l and a crash .
- Always make sure that the tota l load be­
ing transported -including the we ight of
a tra ile r hitch and the tongue weight of a
loaded trailer -does not make the veh i­
cle heav ier than the veh icle's Gross Vehi­
cle Weight Rating.
A WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious o r fatal acci­
dent.
- Incorrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle .
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including 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 tire pressures are on the
tire pressure labe l and in the tab le
c:> page 239, Cold tire inflation pressure .Th is
means that the pressure must be checked and
adjusted 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 the tire heats up
as a result of inte rna l fr iction as it flexes in
use. The ti re p ress ure is higher when the tire
h as warmed up than when it is "cold."
It is the inflat ion pressure in a "cold " tire that
counts. Therefo re, you shou ld neve r let air out
Tire s an d wheel s 241
of a wa rm tire to match "Cold tire inflat ion
pressure" recommendations
c:> page 239. T he
tires wou ld then be underinflated and cou ld
fail suddenly .
T he t ire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
maximum capacity for the new, orig inal
equipment tires that were on your vehicle at
the time it was manufactured. For the loca­
tion of the labe l
c:>poge 239, fig . 183 .
Most tires lose air natura lly over t ime. They
can a lso lose some air if you drive over a pot­
hole or hit a curb while park ing. It is usually
not possible to see whether the rad ia l tires
used today are underinflated just by looking
at them.
Therefore, be sure to check t ire pressures at
least once a mo nth and a lways before going
o n a long tr ip . Make sure to take the number
of peop le and the amount of luggag e into ac­
count when adjust ing tire p ressu re for a trip -
even one th at yo u wo uld not conside r to be
"long." See¢
page 243, Tires and vehicle
load limits
for mo re important information .
Always use an accura te ti re pressu re gauge
whe n checking and adj usting i nflation pres­
s ur es . Check a ll of the tires and be sure not to
forget the spare tire.
If the pressure in any tire
is too high when the ti re is "cold," let air o ut
of the t ire s low ly w ith 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 k ind of
driv ing you plan to do .
If the pressure in any tire is too low, note the
difference be tween the pressure in the cold
ti re and the pressure you need and add the air
that you need to reach the correct pressure for
the ve hicle load (passengers and luggage) for
t h e tires on you r veh icle as l isted on the on
you r vehicle and in this ma nual a nd the k ind
of driving you plan to do.
Nev er e xceed the ma ximum inflation pre s­
s ure lis te d on the tir e sidewall for any re a­
son.

24 2 T ire s and wheel s
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the correct
tire pressure for the t ires on your vehicle.
I t is important to check the tire pressu re when
the tires a re cold.
- Read the requ ired t ire pressure from the tire
pressure label. The tire pressure labe l is lo ­
cated on the drive r's side 8-p illar.
- T urn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressu re gauge on the valve.
- The tire pressures should only be checked
and adjusted when the tires are cold. The
sl igh tly ra ised p ressu res of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the va lve stem cap on the valve .
When should I check the ti re pres sure ?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always before start ing a jou rney. Do not
fo rget to check the tire pressure for the spare
wheel
i::!> page 258.
When should I adju st the tire p re ss ure s?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then
sto re t he new ti re press ures in the t ire pres­
sure mon itor ing system*
i::?> page 253.
_8 WARNING
Incorrect tire pressures and/or underinf la­
tion can lead sudden tire failure, loss of
contro l, co llision, ser ious persona l injury
or even death.
- When the warning symbo l
RI] appears in
the instrument cluster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla­
t ion can cause increased t ire wear and
can affect the handling of the veh icle and
stopp ing ability. -
Incorrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and sudden de­
flation, caus ing loss of veh icle control.
- The driver is responsible for the correct
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­ ed on a sticke r on the dr iver's s ide 8-pil­
lar.
- Only when all tires on the vehicle are fil­ led to the correct pressure, the t ire pres­
sure mon itor ing* system can work cor­
rectly.
- The use of incorrect t ire p ressure va lues
can lead to acc idents or other damage.
Therefore it is essential t hat the drive r
observe the spec ified tire pressure values
for the tires and the correct pressures for
the function of the t i re press ure monitor­
ing system*.
- Always inflate tires to the recommended
and correct ti re press ure before driving
off.
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
tion to check the t ire p ress ure and add
a ir as req uired.
Q) Note
Driving w ithout valve stem caps can cause
damage to the tire valves. To prevent this,
always make sure that factory insta lled
valve stem caps o n all whee ls are sec urely
mounted on the valve.

@ Tips
Check carefully to make sure the hook-up
is secure before moving the car up the flat­
bed truck ramp.
Vehicle transport
Whenever you have your vehicle transported,
be sure to note the following:
(D Note
Mount the tie-down chains/cables over the
running surface (circumference) of the
tires. Never secure the vehicle by the axle,
the suspension struts or the front or rear
towline eye. For technical reasons, the
pressure in the suspension struts may
change during the transport and this will
adversely affect vehicle handling.
Lifting vehicle
Lifting with workshop hoist and with
floor jack
The vehicle may only be lifted at the lifting
points illustrated.
