2016 AUDI A8 check oil

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.

Driving and th e en vironm ent
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
.,. Try and keep well below your car's maximum
speed .
Accelerating gent ly reduces fue l consumption,
engine wear, and does not disturb the environ­ ment.
Fue l consumption, exhaust emissions and engine
noise increase d isproportionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumption will be reduced by
one half. Never drive faster than the posted
speed limit and weather conditions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
.,. Shut the engine off when you are not driv ing
the vehicle.
.,. Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automatically reduced for
veh icles with the Start-Stop-System*. It is effi­
cient to switch off the eng ine in vehicles without
the Start -Stop -System when stopped at ra ilroad
crossings and long red lights . Turning the engine
off for just 30-40 seconds saves more fuel than is bu rned by starting the engine aga in.
It takes a long t ime for the engine to warm up
fu lly when it is running at idle . However, wear
and noxio us em iss ions are espec ially high when
the engine is wa rm ing up. So you sho uld drive
away as soon as you start the engine a nd avoid
running at high rpms while the engine is still
warming up.
(D Note
Do not leave engine idling unattended a fter
starting . If warn ing lights should come on to
indicate improper operation, they wou ld go
unheeded. Extended idling a lso produces
heat, wh ich co uld result in overheat ing or
200
other damage to the vehicle or othe r proper ­
ty.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
.,. Have you r veh icle serviced at regula r interva ls.
By hav ing your veh icle regularly serv iced by an
Audi dealer he lps to ensure that it runs p roperly
and e conomi cally. The cond ition of you r vehicle
not only affects its safety and ab ility to hold its
val ue, it also affects
fuel con sumption .
Check your oil each t ime you fill your tank .
The amount of oi l used is related to engine load
and speed .
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile­
age has been driven .
You must drive your vehicle about 3,000 mi les
(5,000 kilometers) before you can properly as­
sess oil consumpt ion.
This also app lies to fue l consumption and engine
output .
(D Note
-Have your ve hicle ma intained properly and
in accordance with the se rvice recommenda ­
tions in your Warranty
& M aintenance book­
let. Lack of proper maintenance as we ll as
improper use of the veh icle w ill impair the
function of the em ission control system and
cou ld lead to damage .
- Do not alter or remove any component of
the Emission Contro l System u nless ap­
proved by the man ufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ign ition w ires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
impo rtant ve hicle compone nts.

(D Note
-Me thanol f uels which do not mee t these re­
quirements may ca use corros ion and dam­
age to plastic and rubber components in the
fuel system .
- 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.

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 ­
ing and running. Depend ing on the sea son, gas
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
and the engine . Such damage will not be
