2014 AUDI S4 instrument cluster

238 Tire s and whee ls
- Adjust the tire pressure to the load you are
carrying.
- Reinsta ll the va lve stem cap on the valve .
When should I ch eck the tire pres sur e?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and a lways before starting a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I adj ust the tire p re ss ures?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
o r replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then initi­
alize the new tire pressures in the tire pres­
sure monitoring system*~
page 249.
A WARNING
Incorrect tire pressures and/or underinf la­
tion can lead sudden tire failure, loss of
control, collision, ser ious personal injury
or even death.
- When the
RI] warning symbol 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
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
t ire pressures fo r all tires on the vehicle .
T he applicable p ressure va lues are locat­
ed on a sticker on the driver's side B-pil ­
lar.
- Only when a ll ti res on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring system* can work cor­
rect ly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified t
ire pressure values
for the tires and the correct pressures for
the function of the ti re pressure monitor­ing system*.
- Always inflate tires to the recommended
and correct t ire pressure before dr iv ing
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 cont rol.
- 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 wh eel immediately, drive at
reduced speed to the nearest service sta­
tion to check the t ire p ressure and add
air as required.
Q) Note
D riving without valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure tha t factory insta lled
valve stem caps on all whee ls are sec urely
mounted on the valve.
@ For the sake of the environment
U nderinflated tires w ill also incre ase the
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any tire can carry.
A vehicle that is over loaded will not handle
well and is more d iff icult to stop. Overloading
can not only lead to loss of vehicle control,
but can also damage important parts of the
vehicle and can lead to sudden tire fa ilure, in­
clud ing a b lowout and sudden deflation tha t
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are .,..

Tire pressure monitoring system
UJ General notes
Applies to vehicles: with tire pressure monito ring system
Each t ire, i ncluding the spare (if provi ded),
should be chec ked month ly w hen cold and in­
flated to the inflation pressure recommended by the vehicle manufacture r o n the vehicle
placar d or tire infla tion pressure label. (If your
veh icle has t ires of a diff erent siz e than the
size ind icat ed on the vehicle p lacard or tir e in ­
flation pressure label, you should deter mine
the proper tire inflation pressure for those
tires).
As an added safety feature, your vehicle has been equipped with a tire pressure monitor ing
system (TPMS) that illuminates a low tire
pr essu re tellta le when one or mo re of your
tires is significantly under -inflated . Accord ing ­
l y, when the low tire p ress ure telltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driv ing on a signif icantly un­
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under -inflation al ­
so reduces fuel efficiency and tire t read life,
and may affect the ve hicle's handling and
stopping ab ility.
Please note that the TPMS is not a subst itute
for p roper t ire mainte nance , and it is the dr iv­
e r's responsib ility to ma inta in cor re ct t ire
p ress ure, even if under- infla tion has no t
reached the leve l to trigger ill umin ation of the
TPMS low tire pressure telltale.
Your veh icle has also bee n equ ipped with a
TPMS malfunc tion indica to r to indica te when
the system is not opera ting properly. The
TPMS mal function indicato r is combined wi th
the low tire press ure tellta le . When the sys­
tem detects a malf unct ion, the te lltale will
flash for approximately one minute and then remain cont inuo usly illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the ma lf u nction ex ists .
Tire s an d wheel s 249
When the malfunction indicator is illum inat ­
ed , the system may not be ab le to detect or
s ignal low tire pressure as intended . TPMS
malfunctions may occur for a var iety of rea­
sons, including the insta llation of replace­
ment or alternate tires or wheels on the vehi ­
cle that p revent the TPMS from functioning
proper ly. Always check the TPMS malfunction
te lltale after rep laci ng one or more tires o r
whee ls on you r vehicle to e nsur e th at the re­
placement or alterna te t ires and wheels a llow
the TPMS to continue to func tion p roperly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indica tor in the instrument
cluster informs you if the tire pressure is too
Low or if there is a system malfunction.
Fi g. 194 D isp lay: un de rin flat io n warni ng
U sing the ABS sensors, the tire pressure mo ni­
toring system compares the tire tread c ircum­
ference and vib rat ion character istics of the in­

ment cluster with a

display goes o ut afte r 5 seconds . The driver
message can be displayed again by pressing

have the ma lfunction corrected.
A WARNING
- If the tire pressure indicator appears in
the instrument cl uster d isplay, one or
more of your tires is s ignificantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braki ng
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pres sure to the proper p res­
s u re as in dic ated on the vehicle 's t ire
pressure label¢
page 234 . Driving on a
significantly under-inf lated tire ca uses the tire to overheat and can
lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly .
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi ­
cato r may be delayed .
-Ask your authorized Aud i dea ler if run­
flat t ires may be used on you r vehicle.
Your vehicle registration becomes invalid
if you use these t ires when not perm it­
ted. Damage to your vehicle or accidents
could a lso result.
(D Tips
- The tire pressure mon itoring system
stops work ing whe n there is an ESC/ABS
m alfu nction.
- Us ing snow chains may result in a system
ma lf u nction.
- The tire pressure mon itoring system on
your Audi was deve loped using tires with
t he "AO" or "R O" ident ifi cat ion on the
tire sidewa ll¢
page 242 . We recom ­
mend using these tires.
Reset tire pressure monitoring system
Appl ies to vehicles: wit h tire p ressu re mo nito rin g system
If the tire pressure is adjusted, wheels are ro ­
tated or changed, the TPM5 must be reset via
radio or MMI*.
" Before resetting t he TPM S, the c urrent pres­
sures of a ll four tires must correspond to
the specified values . Ad just the tire p ressu re
and reset the pressure in the tire pressure
mon itoring system according to the load
you are carrying
