2014 AUDI RS7 SPORTBACK warning light

224 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 158.
Disconn ecting the battery terminal s
Some vehicle functions (power w indow 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
e lectrical system when absolutely necessary
for repairs .
Vehicles not driven for l ong 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 il ity over a longer period
¢
page 195. Some of the convenience func­
tions may not operate, s uch as the inte rior
lights or power seat adjus tment. The conven­
ience f unctions will be available again when
you switch on the ignition and start the en­ gine.
Winter operation
D uring the winter months, ba tte ry capaci ty
tends to decrease as tempe rat ures d rop . This
is because more powe r is also consumed while
starting , and the headlights, rear window de­
fogger, etc., are used more often.
Avoid unnecessary power consumption, par­
ticular ly in c ity traffic or when t raveling on ly
short distances. Let you r authorized Audi
dea ler check the capacity of the vehicle bat ­
tery before winter sets in
¢ page 226. A we ll
charged battery w ill not only prevent starting
prob lems when the weather is cold , but w ill
also 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 .

cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive problems. Wash hands after han­ dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is on or when the en­ gine is running, otherwise, you will dam­
age electronic components in the e lectri­
cal system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced.
- When opening the doors, the windows
lower approximately 10 mm automati ­
cally . This function is not available when
the battery is disconnected, which
means there is a risk that the door sea l
or the window could be damaged.

CD Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as control units, relays, radio, etc., as well
as the battery charger .
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery .
Intelligent energy management in your vehi­
cle is respons ible for distributing the electri­
cal energy throughout your vehicle
c::> page 195. The intelligent energy manage­
ment system w ill keep the engine battery
charged bette r than vehicles w ithout t his sys­
tem. To make sure the additional electr ica l en­
ergy is available once again after you have
changed the battery, we recommend that you
install batteries of the same type and manu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery hous ing. Your
author ized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­
rectly after replac ing the battery.
The new battery must have the same capacity,
voltage (12-volts), amperage, const ruct ion
and p lug sealing.
When installing the battery, make sure the ig­
n ition and all electr ical consumers are sw itch­
ed off .
CD Note
Make sure the ventilation hose on the s ide
of the battery is connected, otherwise
fumes or battery ac id can leak out.
@ For the sake of the environment
Because of the problem of proper d isposal
of a battery, we recommend your author­
ized Aud i dealer change the battery for
you . Batteries contain su lfuric ac id and

-Do not change the tire pressure when the
temperature of the tire is high. This
could result in serious damage to the tire
and even cause the tire to burst, increas­
ing the risk of an accident.
- A tire with low pressure flexes more. This
heats the tire up too much . Th is could
cause the tread to separate and even
cause the tire to burst, increasing the
risk of an accident .
- The tire pressure monitoring system
does not warn about damage or defects
in the tire construct ion that could cause
the tire to burst, for examp le. Inspect
your ti res regularly.
@) For the sake of the environment
Low tire pressure increases fuel consump­
tion and tire wear.
(D Tips
-If tires are replaced, the sensors/valves
do not need to be removed or replaced.
Just replace the valve stem and, if neces­
sary, the valve and the wheel electronics.
If you have questions, see your author­
ized Audi dealer or a qualified workshop.
- Using the tire mobility kit can results in
an incorrect display or a malfunction in
the tire pressure monitoring system.
Have the sensors replaced by an author­
ized Audi dealer or a qualified workshop.

Storing new tire pressures
-
Correctly stored tire pressure specifications
are necessary for reliable tire pressure moni­
toring.
.,. Check the tire pressures in all wheels.
.,. If necessary, correct the tire pressure ac­
cording to the specifications on the sticker
on the side of the driver's door . Only correct
the pressure in tires whose temperature is
approximately the same as the ambient
temperature. If the temperature of the tire
is higher than ambient temperature, the tire
pressure must be increased approximately
0.2 bar above the value on the sticker.
.,. Switch on the ignition.
.,. Select :
I CARI function button > Car systems
> Tire pressure monitoring > Store tire pressures.
After storing,
the tire pressure
monitoring system measures the current
tire pressures and stores them as the new
specified pressures.
,. If the changed tire pressures are not dis­
played in the Infotainment system, drive the
veh icle for approx imately 10 minutes so
that the sensor signal from the wheels is re­
ceived aga in .
During this adaptation phase,--,--is displayed
for the pressure and temperature and the tire
pressure monitoring system is only partially
available.
It only provides a warning if one or
more tire pressures is be low the min imum
permitted spec ified pressure . If this is the
case, the
[fJ] indicator light appears with a
message.
