2015 AUDI RS5 COUPE maintenance

Care and cleaning
A WARNING
- Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourse lf
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect may be delayed due to moisture on the
brake rotors or ice in the winter . The brakes
must be dried first w ith a few careful brake
applications.
@ Note
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be fo lded in and out us ing the power folding
funct ion.
- To prevent pa int damage, do not wash the
vehicle in direct sunlight .
- To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­ moved.
@ For the sake of the environment

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¢

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

under controlled conditions on a specified gov­
ernment test course.
For example, a tire graded 150 would wear one
and one ha lf (11/2) times as well on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band
C. Those grades represent the tire's
ability to stop on wet pavement as measured un­
der controlled conditions on specified govern­ ment test surfaces of asphalt and concrete . A tire
marked C may have poor traction performance
¢ .&. .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
¢ .&. .
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un ­
der the Federal Motor Vehicle Safety Standard No. 109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law .
A WARNING
-
The traction grade assigned to this tire is
based on stra ight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplan ing or peak traction charac­
teristics.
Wheels
A WARNING
The temperature grade for this tire is estab­ lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in comb ination , can cause heat buildup and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tir es that are
properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
ill General notes
Applies to vehicles: with tire pressure monitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires) .
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you shou ld stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi­
cant ly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure, even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale. .,.

Maintenance
General '
Your vehicle has been designed to help keep
maintenance requirements to a minimum. How­
ever, a certain amount of regular maintenance is
still necessary to assure your veh icle's safety,
economy and reliability. For deta iled vehicle
maintenance consult your Warranty & Mainte­
nance booklet .
Under difficult operating conditions, for exam­
ple at extremely low outs ide temperatures, in
very dusty regions, when towing a trailer very fre­
quently , etc., some service work should be per­
formed between the intervals specified. This ap­
plies particularly to:
- oil changes, and
- cleaning or replacing the air filter .
'
@) For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that emission standards are
maintained, thus minimizing adverse effects
on the environment.
Important considerations for you and your
vehicle

N 1.1'1 ,....,
today's automobiles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by vehicle owners .
Also , s afety a nd
en viro nm enta l
concerns place very strict limits
on the nature of repairs and adjustments to en­
g ine and transmission parts which an owner can
perform.
Maintenance, adjustments and repa irs usua lly re­
qu ire spec ial tools, testing devices and other
equ ipment available to specially trained work­
shop perso nnel in order to assure proper per­
formance, reliab ility and safety of the vehicle and
its many systems.
Improper ma intenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of se rv icing in accordance with
the m aintenance schedule may be a condi tion for
upho ld ing a possib le warranty cla im made w ith in
the warranty period .
Above all, operational safety can be adversely af­
fected, creating unnecessary r isks fo r you and
your passengers.
I f in doubt about any servicing, have it done by
your author ized Audi dealer or any prope rly
equ ipped and qua lified workshop. We st rongly
urge you to give your authorized Audi dealer the
opport unity to perform all sched uled mainte­
nance and necessary repairs. Your dealer has the
fac ilities, origina l parts and trained specia lists to
keep yo ur vehicle runn ing properly.
