2016 AUDI S5 COUPE maint

Check ing and F illing
Using the proper engine oil is impo rtant for the
functionality and service life of the engine. Your engine was facto ry-filled with a h igh-quality oi l
which can usually be used throughout the entire
year.
@) Note
Your Limited New Vehicle War ranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warran ty
& Maintenance booklet.
- Use only a high quality eng ine oil t hat ex-
p ressly complies with the Audi oil qua lity
standard specified for your vehicle's engine .
Using a ny o ther oil can cause serious engine
d am age.
- D o not mix any lubricants o r other addit ives
i nto the engine oil. Doing so ca n cause en­
g ine damage.
(D Tips
I f you need to add oil and there is none availa­
ble t hat meets the Audi o il quality standard

Engine oil consumption
The engine in your vehicle depends on an ade­
quate amoun t of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubr ication and coo l­
ing of in ternal engine components, all internal
combustion eng ines consume a certain amou nt
of oil. Oil co nsumption varies from engine to en­
g ine and may change significant ly over the life of
194
th e engine. Typically, engines w ith a specified
break-in period (see
r=:> poge 177) consume more
o il dur ing the b reak-in per iod than they consume
after oil consumption has stabili zed .
U nder normal cond itions, the rate of oil con ­
sumption depends on the q ua lity and viscosity of
the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the ambient tem­ perature and road condit ions. Further factors are
the amo unt of o il di lution from water condensa ­
t ion or fuel residue a nd the oxidation level of the
o il. As any engine is subject to wea r as mileage
builds up, the o il cons umption may increase ove r
t i me unt il repla ce m ent of wo rn components m ay
be come necessary .
With a ll these va riab les coming into p lay, no
sta ndard rate of o il cons umption can be estab­
li sh ed or spec ified . T he re is no alte rn ative to reg­
ul ar and frequen t checking of the oi l level, see
Note .
If the yellow engine oi l leve l wa rning symbo l Ill
in the instrument clus ter lights up , you sho uld
c h eck t he o il level as soon as possible
r=:> page 195 . Top off the oi l at your ea rliest con­
venience

A WARNING
Before you check anyth ing in the engine com­
partment, always read and heed all WARN­
INGS
r=:> .&. in Working in the engine compart­
ment on page 191.
@ Note
D riving wit h an insuffic ient oil level is like ly to
cause severe damage to the eng ine.
(D Tips
- The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it . Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip .
-If you have the impress io n your e ngine con­
sumes excessive amou nts of oil, we recom-
mend th at yo u consult an authori zed A udi .,.

Check ing and F illing
@ For the sake of the environment
- Under no circumstances can the oil come in
contact with the sewage network or the soil.
- Observe and fo llow legal regulations when
disposing of empty oil containers.
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi dealer or a qualified service sta­
tion .
Before you che ck anything in the eng ine compart ­
ment,
always read and heed all WARNINGS ¢ A
in Working in the engine comportment on
page 191.
The engine oil must be changed according to the i n tervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricat ing propert ies of oil diminish gradually
during normal vehicle use.
Under some circ umstances the eng ine oi l sho uld
be changed more frequently. Change oil more of­
ten if yo u drive most ly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic cond it ions , or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
look dark after t he engine has been run ning for a
short t ime . T his is normal and is not a reason to
cha nge the oil mo re often than recommended .
Because of the prob lem of proper disposal, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil c hanged by an aut ho rized
Audi dealer o r
a qualif ied se rvice station .
If you choose to change your o il yourself , please
note the following important informat ion:
A WARNING
To re duce the risk of pe rsonal injury if you
must c hange t he engine oil in your ve hicle
yo urs elf:
- W ear eye protection .
196
-
-To reduce the r is k of burns from hot engine
oil, let the engine cool down to the touch.
- W hen removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm pa rallel to the ground to
he lp prevent hot oil from run ning down your
arm .
- Drain t he oil into a container designed for
this purpose, one large enough to hold at
leas t the tota l amou nt of oil in you r engine.
- Engi ne oil is poisonous. Keep it well out of
the reach of childre n.
- Continuous contact wit h used engine o il is
ha rmf ul to your skin. Always protect your
skin by washi ng oil
off thoroughly with soap
and wate r.

Cooling system
Coolant '
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter.
The coolin g system is sealed and generally re­
quires little attention .
The coo lin g sys tem h as been filled a t the fac to ry
wi th a pe rmanent coolan t which does not need to
be changed. The coo lant consists of a mixture of .,.

.... N
0 I­co .... .... specially conditioned water and the man ufactur­
er's glycol-basedcoo lant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­
e ls; 60% for Canadian models). This m ixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing system from corrosion and scaling.
It also
raises the boiling point of the coolant .
Do not reduce the concentration of the coolant in
the summer by adding plain water.
Th e propor­
tion of coolant addit ive must be at l eas t 50° /4
but not more th an 60 %
to maintain antifreeze
p rotection and cooling efficiency. If the coolant
frost protec tion is too low, the coolant co uld
freeze and damage the vehicle heating and en­
gine cooling system.
F or yea r-round driving, antifreeze is added at the
factory for temperatures down to:
- -31 °F (- 35 °C) USA
- -40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
Q &. in Working in the engine compart­
ment on page 191.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­
dit ions. This is especially important if you
li ve in a reg ion where the w inte r is ext reme­
l y co ld. If ne cessary, in cre ase the proport io n
of coo lant add itive to 60%.
- When addi ng coolant addit ive to you r cool­
i ng system, remember:
- We recommend using only coolant addi­
tive Gl2++ or Gl3 for your ve hicle. T his
coolant additive is available at authorized
Audi dea lers. Othe r types of antifreeze can
significant ly reduce cor ros ion p rotection .
Check ing and Filling
The resulting co rrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator lea k sealant
to your vehicle's engine coolant. Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could resu lt in damage not cov­
ered by your New Veh icle Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

Aud i dealer or qualified workshop and the cause
corrected . If the brake flu id level is too low, the
b rake warning/indicator light will i llum inate.
Contact a n author ized Audi dealer
immediately .
{D) Tips
The brake fluid reservoir is located under­
neath the cover .
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs mo isture from the air. If the
water content in the b rake fluid is too high, cor­
rosion in the brake system may resu lt afte r ape ­
riod of t ime. The boiling poi nt of the brake flu id
will also decrease cons iderably and decrease
b raking perfo rman ce.
Therefore, the brake fluid must be changed
every
two year s.
Always use new brake fluid wh ic h con­
forms to Fede ral Motor Veh icle Standard "FMVSS
1 16 DO T 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we recommend that yo u have the
brake fl uid changed by yo ur autho rized
Audi
dealer .
Your dealer has t he corre ct tools, t he
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed orig inal container out of
the reach of chi ldren!
200
- Bra ke fa ilure ca n result from old or inapp ro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid t hat meets SA E speci­
fi ca ti on
J 170 3 and con forms to Federa l
Motor Ve hicle Standard 116 . Always check
wi th yo ur autho rized Audi dea le r to make
s ur e yo u are using the correct brake fluid .
The correct type of brake flu id is also ind i­
cated on the b rake fluid reservo ir .
- The brake fluid m ust be new . Heavy use of
the brakes can cause a vapo r lock if the
brake fluid is left in the system too long .
This can se riously affect the efficiency of
the b rakes as well as your safety . This
could resu lt in an accident .
(D Note
Brake fluid will damage the paint of your veh i­
cle.
@ For the sake of the environment

omme nd that you have the bra ke f luid
changed by yo ur autho rized Aud i dea le r.
Battery
, General information
U nder normal operating condit ions, the battery
i n your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the elect ro ­
lyte level c hecked by an au thorized Aud i dealer o r
qualified workshop. The electro lyte level shou ld
a lso be che cked each time the battery is c ha rged
c:!,> page 202.
Have the batte ry chec ked when you take yo ur ve­
hicle in for service. You are we ll adv ised to re­
pla ce a battery tha t is older than 5 yea rs.
With certain types of airbag deployment, t he
batte ry is d iscon nected from the ve hicle electri­
ca l system for safety reasons

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra­
t io ti res. These t ires have been tho rough ly tested
a n d been se lected specifically fo r yo ur model for
t he ir superb performance, road feel and handling
under a variety o f driving conditions. Ask your au­
thor ized Audi dealer for more details .
The low aspect ratio of these t ires is indicated by
a numera l of
55 or l ess in the tire 's size designa ­
tion . The numera l represents the rat io o f the
tire's sidewall height in relat ion to its tread width
expressed in pe rc e ntage. Conventional t ir e s hav e
a height/w idth rat io of 60 or more.
The performan ce of low- aspect- ratio tire s is par­
ticularl y sensiti ve to imp roper inflat ion pres­
sure . It is therefore import ant that low a spect
ratio tires are infl ated to the specified pressure
and that the inflation pre ssure is regularl y
checked and mainta ined . Tire pre ssure s shoul d
be checked at least once a month and alwa ys
befor e a long t rip
¢ page 215.
What you can do to avoid tire and rim
damag e
Low aspect rat io tires can be damaged more easi­
ly by impact with potho les, curbs, gull ies or
Wh eel s
ridges on the road, particular ly if the tire is un ­
deri nflated.
In orde r to min imi ze the occurrence of imp act
damage to the tires of yo ur vehicle , we recom­
mend that you observe the following preca u­
tions:
- Always ma intain recommended inflat io n pres­
sures. Check yo ur ti re pressure every 2,000
miles (3,000 km) and add air if necessary .
- Dr ive ca refully on roads w ith po tholes, deep
gullies or ridges . The impac t from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immediate ly inspect your
tires or have th em inspected by th e nearest au ­
thorized Audi dealer. Replace a damaged tire as
soon as possible.
- Inspect you r tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see . Damage can lead to loss of air and
underinflation, wh ic h could eventually cause
tire fa ilure. If you believe that a tire may have
been damaged , replace the tire as soon as pos­
sib le.
- These tires may wear more quickly than others .
- Please also remember that, while these tires
delive r responsive ha ndling, they may ride less
comfortably a nd make more noise than other
choi ces.
Reduced perfo rmance in winter /cold se ason
conditions
All tires are des igned for certai n purposes. The
low aspect ratio, ultra high performance tires
o rigi na lly installed o n your veh icle are intended
f or maximum dry and wet road per formance and
handling . They are not suitable for co ld, snowy or
icy weather conditions . If you drive under those
c ircumstances, you should equip your vehicle
with all-season or winter tires, which offer better
tract ion under those condi tions. We suggest you
use the recommended snow or all-season tires
spec ified for your veh icle, or their equiva lent .
Refer to¢
page 220 for more detailed informa­
t ion regarding winter tires .

.... N
0 I­co .... .... check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Under-inflation
a lso reduces fuel efficiency and tire tread life,
and may affect the vehicle 's handling and stop ­
p ing ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the level
to tr igger illum inat ion of the TPMS low tire p res­
sure telltale.
Your veh icle has also bee n eq uipped w ith a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operat ing properly . The TPMS ma l­
function ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system detects a
malfunct ion, the te lltale will flash fo r approx i­
mately one mi nute and then remain continuo usly
illuminated. This sequence will continue upon
subseq uent veh icle start-ups as long as the ma l­
function ex ists .
When t he malfunction indicator is ill uminated,
the system may not be ab le to detect or signal
l ow tire press ure as intended. TPMS ma lf u nctions
may occur for a var iety of reasons, including the
installation of replacement or alternate t ires or
