2015 AUDI RS5 COUPE ABS

Checking and F ill in g
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the a ir. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after a peri­
od of time. The boiling point of the brake fluid
will also dec rease conside rably and dec rease
b ra ki ng perfo rman ce.
Therefore, the brake flu id must be changed
e ve ry
two y ear s.
Always use new b rake fluid wh ic h con­
forms to Fede ral Motor Vehicle Standard " FMVSS
1 16 DOT 4".
The brake fluid reservoir can be difficult to reach,
therefo re , we recommend that yo u have the
b rake fluid changed by your authori zed
Audi
dealer . Your dealer has the cor re ct too ls , the
righ t brake fluid an d the know-how to do t his for
you.
A WARNING
- Brake fluid is po isonous. It must be stored
only in the closed orig inal container out of
the reach of children!
- Brake fai lure can result from old o r inappro­
pr iate bra ke fluid . Observe these p recau­
t ions:
- Use on ly bra ke fluid t hat meets SA E speci­
fication
J 17 03 and confo rms to Fede ral
M otor Vehicle S tand ard 116 . Always check
wit h your author ized Audi dea ler to make
sure yo u are using the correct brake f lui d.
The cor rect type of b rake fluid is a lso indi­
cated on the bra ke fluid reservo ir.
- The brake fluid m ust be new. Heavy use of
the bra kes can cause a va por l ock if the
brake fluid is left in the system too long.
This ca n ser iously affect the effic iency of
the brakes as we ll as your safety . This
co uld res ult in an accident.
@ Note
Brake f lu id will damage the paint of y our vehi­
cle.

® For the sake of the environment
Because of t he prob lem of prope r disposal of
brake fluid as well as the special tools re­
q uired and the necessary expert ise, we rec­
ommend that yo u have the brake f lu id
changed by your autho rized Aud i dea le r.
Battery
General information
Under normal operating conditions, the battery
i n your A ud i does not need any maintenance .
With
high outside temperatures or long dai ly
drives we recommend that you have the e lectro­
l yte level checked by an aut horized Aud i dea ler or
qualified workshop . The e lectrolyte leve l should
also be chec ked each time the batte ry is cha rged
¢ page 198.
Have the battery checked when you take your ve­
hicle i n for service . You are well adv ised to re ­
place a battery that is older than 5 years .
With certain types of airbag deployment, the bat­
tery is disco nnected from the ve hicle elect rical
system for safety reasons
¢ A in Repair , care
and disposal of the airbags on page 141 .
Disconnecting the battery terminals
Some vehicle functions (power window reg ula­
tors, for example) are lost if the battery te rm i­
nals are d isconnected . These funct ions have to be
r elearned after the battery t ermina ls are con­
nected again . To prevent t his, the battery sho uld
o nl y be disconnected from the ve hicle e lectr ica l
system when absolute ly necessary fo r rep airs.
Vehicles not driven for long periods
If you do not drive your vehicle ove r a period of
several days or weeks, electrical components are gradua lly cut back or sw itched off . T his reduces
energy cons umption and mainta ins start ing ca­
pabili ty ove r a longer period¢
page 175.
Some of the convenience funct ions may not ope r­
ate, such as the inter ior lights or the power s eat
adjus tment . The conve nien ce f unct io ns w ill be
ava ila ble again when you tu rn on the ig nition an d
star t the eng ine. ..,..

Wheels
you would like to use different tires, please note that the tires
may perform differently even if
they are the same size¢
&-
~ If you would like to equip your
vehic le with a tire/rim combina­
tion that is different from what
was installed at the factory, con ­
sult with an authorized Audi dealer or authorized repair facili­
ty before making a purchase
¢ & .
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds .
.&._ 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
20 4
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 .
-Only use tires that are more than 6 years old when abso­lutely 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 .

Wheels
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys ­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi ­
mately one minute and then remain continuously
illuminated . This sequence will continue upon
subsequent veh icle start-ups as long as the mal­
function ex ists.
When the malfunct ion indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, incl uding the
installation of rep lacement or a lternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction tellta le after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.
If the Tire Pressure Monitoring System
indicator appears
A pp lies to veh icles: w ith tire pressure moni toring sys te m
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 173 In stru ment cluste r: indicator light with message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires . If the pressure changes in one or more
tires, this is indicated in the instrument cluster
d isp lay w ith an ind icator light
RE and a message.
214
If only one tire is affected, the location of that
tire will be indicated .
The tire pressures must be stored in the Infotain ­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or rep lacing a tire on
your vehicle ¢
page 215. The tire pressure moni­
toring system on ly monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢ page 206, fig. 172 .
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the t ire pressure in one or more tires is too low .
- the tire has structural damage.
- the tir e was replaced or the tire pressure was
changed and it was not stored
¢ page 215.

switching the ignition on or while driving and the
RE indicator light in the instrument cluster
blinks for approximately one minute and then

store the correct tire pressures
¢ page 215. If
the indicator light does turn off or turns on aga in
after a short period of time, drive to your author­
i zed Audi dealer or qualified repair facility imme­
diately to have the ma lfunct ion corrected.
,&. WARNING
- If the tire pressure ind icator appears in the
display, reduce yo ur speed immediately and
avoid any hard steering or braking maneu­
vers. Stop as soon as possible and check the
tires and their pressure .
- The driver is responsible for maintaining the
correct tire pressure. You must check the
tire pressure regu larly. .,..
