218 Check ing and filling
Di sconnect ing the batt ery terminal s
Some vehicle functions (power window regu­
l ators, 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 period 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 capab ility over a longer period
~ page 182.
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 temperatures drop . This
is because more power is also consumed while
start ing, and the headlights, rear window de­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in c ity traffic or when traveling only
short d istances . Let you r authorized Audi
dealer check the capacity of the vehicle bat­
tery before winte r sets in
~ page 219. A well
charged battery w ill not only prevent starting
prob lems when the weather is cold, but wi ll
a lso last longer .
(D Tips
If your vehicle is left standing for severa l
weeks at extremely low temperat ures, the
veh icle battery should be removed and
stored where it will not freeze. This w ill
prevent it from being damaged and hav ing
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
th ing in the luggage compartment,
read and

Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
F ig. 190 Display: underinflatio n warn ing
Using the ABS sensors , the t ire pressure mon i­
toring system compa res the t ire tread circum­
fe rence and v ibration characteristics of the in­
d iv idual tires. If the pressure decreases in one
or mo re tires, th is is indicated in the instru ­
ment cluster with a
ti] warn ing symbol and a
message ¢
fig. 190. The driver message in the
disp lay goes out after S seconds. The driver
message can be d isplayed again by pressing
the
! S ET ! button. If only one tire is affected,
the display will indicate its pos ition .
T he t ire pressure monitoring system must be
reset via radio or MMI* each t ime the pres­
sures are adjusted (e.g . when sw itching be­
tween partia l and full load pressure) or after
changing o r replacing a t ire on your vehicle
¢

tors the tire p ressure that you have prev iously

sign ificantly under-inflated tire causes
the t ire to overheat and can lead to tire

impair the vehicle's ha ndling and stop­
ping ab ility .
- The drive r is responsib le for maintaini ng
the co rrect tire pressures . You must
check the tire pressures regu larly. .,..

242 Tires and wheels
-Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor indi­
cator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle.
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your vehicle or accidents
could also result.
@ Tips
-The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system malfunction .
- The tire pressure monitoring system on
your Audi was developed using tires with the
"ROl" identification on the tire side­
wall ~
page 233. We recommend using
these tires.
Reset tire pressure monitoring system
Applies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or chang ed, the
TPMS must be reset via
radio or
MM!* .
.. Before resetting the TPMS, the current pres­
sures of all four tires must correspond to
the specified values. Adjust the tire pressure and reset the pressure in the tire pressure
monitoring system according to the load
you are carrying
~ page 226 .
.. Turn on the ignition .
.. Select : the
ICAR I function button > Tire pres­
sure monitoring > Store now .
Or
.. Select : the ICA RI function button > Car sys­
tems*
control button > Servicing & checks>
Tire pressure monitoring > Store tire pres­
sures.
@ Tips
Do not store the ti re pressure if there a re
snow chains on the tire.
