2016 AUDI S8 oil temperature

Normal temperature
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under norma l driving conditions . The
LEDs higher up may turn on when the engine is
under heavy load or the exterior temperature is
high. This is no need to worry as long as the.
warn ing light in the instrument cluster does not
illuminate . If the LEDs in the upper area of the
d isplay and the ind icator light . in the instru­
ment cluster display tu rn on , the coolant temper­
ature is too high
¢page 15.
_& WARNING
-Always observe the warning in ¢ page 220,
Working in the engine compartment,
before
opening the hood and checking the engine
coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
could burn yourself. Let the engine cool off
first so that you cannot hear or see any
steam or engine coolant.
(D Note
-Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef­
fect of the radiator. At h igh outside temper­
atures or high engine load, the engine could
overheat .
- The front spoiler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving.
If the spo iler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­
iz ed Audi dealer for assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revo­
lutions per minutes).
If engine RPM drops below 1,500, you should
downshift to the next lower gear. The red area at
the end of the scale indicates maximum permis­
sib le eng ine RPM after the break-in period. Be­
fore reaching this area, move the selector lever
Instruments and indicator lights
to position "D (Drive)" or ease your foot off the
acce lerator pedal.
(D Note
The tachome ter needle should only briefly be
in the red zone: you could damage your en­
gine! The beginning of the red zone varies de­
pending on the engine .
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.
Fuel gauge
The fue l gauge only works when the ignition is
on. If the fuel level drops below 4 gallons (15 lit­
ers), the bottom LED turns red and the indicator
l ight tllturns on
¢page 21. The bottom LED
blinks red when the fue l level is very low .
The possible range based on the current fue l lev­
el is shown in tab@¢
page 23, fig. 4.
(D Note
Never run the tank completely dry. An irregu­
l ar supply of fuel can cause engine misfiring
and fuel could enter the exhaust system. The
catalytic converter could then overheat and
be damaged.
Indicator Lights
Description
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal­
funct ions¢ ,&..
Messages may appear with some indicator lights.
A warning signal will sound at the same time.
The ind icator lights and messages in the center
of the displays may be replaced by other displays.

pollutants in the exha ust gas before they are re ­
leased into the atmosphere.
The exclusive use of unleaded fue l is critica lly im­
portant for the l ife of the catalytic converter and
proper functioning of the engine.
A WARNING
T he temperature of the exha ust system is
high, both when driving and after stopping
the engine.
-
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exha ust system may come in
contact with dry grass, brush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or rustproofing on or near the exhaust mani­
fold, exhaust p ipes, catalytic converter or
heat sh ields. During dr iv ing, the substance
used fo r undercoating could overheat and
ca use a fire.
(D Note
- Be aware that just one tank filling with
le aded fuel will already ser iously degrade
the performance of the catalytic co nverter .
- Do not exceed the correct eng ine oil level
<=;> page 225.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this cou ld cause the
cataly tic converte r to overheat.
- Do not sw itch off the ignition while the veh i­
cle is moving.
- Do not continue to operate your vehicle un­
der these cond it ions, as otherwise fue l can
r each the catalyti c converte r. This cou ld re­
su lt in overheating of the conve rter, req uir­
i ng its replacement.

-Lack of proper ma intenance as well as im ­
proper use of the vehicle wi ll impair the
funct ion o f the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emiss ion Control System is op ­
erating properly, the exhaust gas can have a
su lfu r-li ke exhaust gas sme ll under some op­
erating states. Th is depends on the sulfur
content of the fuel being used. Us ing a d iffer­
ent brand of fuel may help, or fi lling the tank
with lead-free super g rade gasoline.
Diesel particulate filter
App lies to: vehicles with diese l engine
The diesel particulate filter filters nearly all of
the soot part icles out of the exhaus t. The filte r
clea ns itself automat ica lly unde r no rma l dr iv ing
cond it ions. If the fil ter canno t clean i tself (fo r ex­
amp le, because yo u are on ly driving short distan­
ces), the filter becomes clogged with soot and

A WARNING
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel particu­
la te filte r could sta rt a fi re.
-
- Do not apply an underbody protectant in the
exhaust system area or a fire could start.
Shutting down vehicle
If you would like your vehicle to remain inopera­
tive for a longer period of time, contact an Audi

- Do not use fuels that fai l to meet the speci­
fied criter ia in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
ficat ions, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identif ied.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control

- If you experience a loss of fue l economy or
driveability and performance prob lems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended
fuel.
Gasoline additives
Applies to: vehicles with gasol ine engine
A majo r concern among many au to manufactur ­
ers is carbon deposit build- up caused by the type
of gasoline yo u use.
A lthough gasoline grades d iffer from one manu­
f a cturer to ano ther, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
pa rts, such as fue l injectors and intake valves . Al ­
though most gaso line brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
Fuel and R efueling
After an extended period o f using inadeq uate
fuels, carbon deposit bui ld-ups can rob your en­
gine o f peak performance.
(D Note
Damage or ma lf u nction due to poo r fue l qual ­
ity is not covered by the A udi New Vehicle
Limited Warranty .
Diesel fuel
Applies to: vehicles with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM 0975.
Diesel f uel w it h concen tratio ns of b iod iesel h igh­
er than 5 % such as Bl 1, B20 or BlOO are strict ly
prohibited .
Se rvice station fuel p umps are labe led with the
correct f uel i nfo rmat ion for e asy recog nition by
the user.
If the d iesel f ue l pump is no t labeled
ask the station operator what fuel is being dis­
pensed before fil ling up your vehicle .
UL SD No . 2 m ay not be available ou tside the USA
and Canada . Be su re to check befo re t raveling to
other countries .
UL SD No . 2 c an become thic ke r i n ve ry cold tem­
peratures, and this can imp air the engine's s tart ­

stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper ­
at ing your vehicle as usual.
@ Note
- Your vehicle's diese l engine was designed
sole ly for use with ULSD No . 2 . Therefo re,
neve r use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system

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 cooling system is sealed and generally re­
quires little attention.
T he cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed . The coolant consists of a mixture of
specially condit ioned water and the manufactur ­
er's glycol-based coolant additive Gl3 antifreeze
with anticorrosion additives (SO% for USA mod­
e ls; 60% for Canadian mode ls). This m ixture
both ass ures the necessa ry frost protection and
protects metal components in the engine's coo l­
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
Do not red uce the concent ration of the coolant in
the summer by adding p lain water.
The propor­
tion of coolant addit ive mu st be at least 50 %
but not more than 60 %
to mainta in antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
g ine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to :
- -31° F(- 3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
If you must add coolant, use a m ixture of water
and coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
_& WARNING
Before you check anythi ng i n t he engine com­
partment, always read and heed all WARN ­
INGS
¢ .&. in Working in the engine compart­
ment on page 220 .
(D Note
-Befo re winter se ts in, have the coo lant
checked to see if the coolant additive in your
vehicle is sufficient to meet the cl imate con -
Check ing and Filling
ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold. If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember :
- We recommend us ing only coolant add i­
tive Gl2+ + or Gl3 for yo ur vehicle. This
coolant addit ive is avai lab le at aut horized
A udi dealers . O ther types of antifree ze can
significantly reduce corrosion pro tect ion .
The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra ­
diator repair fluid may adversely affect the
function and performance of your cooling system and cou ld resu lt in damage not cov­
ered by your New Veh icle Limited Warra nty .

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.
~ Mark 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.
(i}) Note
-Please note that summer and
winter tires are designed for
the conditions that are typical i n those seasons. Audi recom­
mends using winter tires dur­
i ng the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
236
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 r ims
does not have sufficient corro­
sion protection for th is and
could be permanently dam­
aged by road salt or similar
substances.
