ABS AUDI S4 2016 Owner's Manual

different tire speeds. For this rea­son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires.
&_ WARNING -
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle . Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
Wheels
-Only use tires that are more
than 6 years old when abso­ lutely necessary and drive
carefully when doing so.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage
Fig. 189 Tire profile : treadwear indica­
tor
Tire wear
Check the tires regularly for wear .
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear .
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear. ..

The temperature grade for this tire is estab­lished for a tire that is properly inflated and
not overloaded. Excess ive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
& WARNING
-
-
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
U) General notes
App lies to vehicles: with tire pressure mo nitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
ve hicle manufact urer on the vehicle placa rd o r
tire inflat ion press ure label.
(If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
eq uipped with a tire pressu re monitoring system
(TPMS) that illuminates a low tire pressure te ll­
tale when one or more of your t ires is significant­
ly under- inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper press ure. Driving on a s ignifi­
cantly under-inflated tire causes the tire to ove r­
h eat and can lead to t ire failure. Unde r-inflation
a lso reduces fuel e fficiency and tire tread life,
and may a ffec t the vehicle's handling and stop ­
p ing ability .
P lease note that the TPMS is not a substit ute for
p roper tire main tenance, and i t is the drive r's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
Wh eel s
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not ope rating properly. The TPMS ma l­
funct ion indicator is combined with the low t ire
pressure telltale. When the system detects a
malfunction, the telltale will flash for app roxi­
mately one m inute and t hen rema in continuously
illuminated. This seque nce w ill cont inue upon
s u bsequent vehicle star t-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illum inated,
the system may not be able to detect o r signal
l ow tire p ressure as intended. TPMS malfunct ions
may occur fo r a v arie ty of reaso ns, including the
insta llation of replacement or al ternate tires or
whee ls on the vehicle that p revent the TPMS
from functioning proper ly . Always check the
TPMS ma lfunction te lltale after replacing one or
more tires or wheels on yo ur vehicle to ensure
that the rep lacement or a lternate tires and
wheels allow the TPMS to continue to function prope rly.

The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fi g. 192 Instrument cluster: indicator light with message
Using the ABS sensors, the tire pressure monito r­
ing system compares the tire tread c ircumfer-
ence and v ibration characterist ics of the ind ividu-
al tires. If the press ure changes in one or mo re
