ABS AUDI A4 2013 Owner's Manual

230 Check ing and filling
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is disconnected from the vehicle elec ­
trica l system for safety reasons¢
& in Re­
pair, core and disposal of the airbags on
page 159.
Disconn ect ing the battery terminal s
Some vehicle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
Vehicles not dri ven fo r lo ng p eriod s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main ­
tains starting capabil ity over a longer period
¢ page 192.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment. The conven ience
functions will be ava ilable again when you
turn on the ignition and start the eng ine.
Winter operati on
During the winter months, battery capacity
tends to decrease as temperatu res drop . This
is because more power is also consumed while
start ing , and the headlights, rea r window de­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in c ity traffic or when traveling on ly
short distances. Let you r authorized Audi
dea ler check the capacity of the vehicle bat ­
tery before winter sets in
¢ page 232. A well
charged batte ry w ill not only prevent sta rting
prob lems when the weather is cold, but wi ll
a lso last longer.
(D Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery sho uld be removed and
stored where it w ill not freeze . This will
prevent it from be ing damaged and having
to be replaced .
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor. Before you check any­
t hi ng in the luggage compartment,
read and
heed all WARNINGS
¢ ,& .
Always heed the safety warnings , when work­
ing on the vehicle battery or the vehicle e lec­
trical system to prevent injury.
Th e follo wing WARNINGS are very
important when working on the battery :

Whenever working on the battery or on

injury, accident and even fire . Read and
heed the following WARNINGS:
-

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 253
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. 19 6 Disp 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
[ti wa rning symbo l and a
message ¢
fig. 196. Th e 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 on ly 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 press ure) o r after
changing or rep lacing a tire on your ve hicle

turn
off or if it tu rns o n short ly thereafter, im­
mediately drive your veh icle to an autho riz ed
Aud i dea le r or autho rized repair facility to
have the ma lfunction corrected.
A WARNING
- If the tire pressure indicator appears in
the instrument cl uster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard stee ring 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 238. 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 s idewa ll
c> page 246 . 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 TPMS must be reset via
radio or MMI*.
.. Before resett ing the TPMS, the current 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 ito ring system according to the load
you are carrying
