ABS AUDI S4 2014 Owner's Manual

@ For the sake of the environment
Because of the pr oblem of proper d isposa l
of brake flu id as we ll as the special tools
requ ired and the necessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer .
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by an authorized
Aud i dealer or qualified workshop . The elec­
trolyte leve l should also be checked each time
the battery is charged ¢
page 22 7.
H ave the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢.&.

Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this , the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods
If you do not drive you r vehicle over a period
of severa l days or weeks, elec trical compo­
nen ts are gr adually cut b ack o r swi tched off .

turn o n the ign ition and start the engine.
Winter operation
D ur ing the w inte r mon ths, bat tery capa city
tends to dec rease as tempera tures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear window de­
fogge r, etc., are used more often.
Avoid unnecessary powe r consumpt ion, pa r­
ticular ly in city traffic or when traveling only
sho rt distances. Let yo ur authorized A udi
dealer check the capacity of the vehicle bat ­
tery before w inter sets in
¢ page 227. A well
charged battery will no t on ly prevent star tin g
problems w hen the weather is cold, but w ill
also last longer .
@ Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
stored where it will not freeze . This will
p revent it from be ing damaged and having
to be repla ced .
Working on the battery
Be especially careful when working on or near
the bat tery.
The battery is located in the luggage compar t­
ment under the floor . B efo re you che ck any­
thi ng in the luggage compartment,
read and
heed all WARNINGS

Always heed the safety warnings , when work­
i ng on the veh icle batte ry or t he vehicle e lec­
t rical sys tem to p reven t inju ry.
The following WARNINGS are very
important when working on the battery:
Always heed the following WARNING SYM· BO LS and safety precautions when working

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
dividua l tir es . If the pressure decreases i n one
o r more t ires, this is indicated in the inst ru­
ment cluster with a
RI] war ning symbol and a
message ¢
fig. 194. T he d river message in the
display goes o ut afte r 5 seconds . The driver
message can be displayed again by pressing
the
ISE TI button. If only one t ire is affected,
the d isplay w ill indicate its position.
T he tire pressure monitoring system m ust be
reset via radio or M MI* each time the pres ­
sures are ad justed (e.g. when switc hing be­
tween part ial and f ull load pressure) o r after
changing or rep lacing a tire on your ve hicle

mediately drive your veh icle to an autho riz ed
Aud i dea ler or autho rized repair facility to
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
