2014 AUDI S7 engine oil

overheat, premature wear and increased
stopp ing distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­ ings will be cleaned off after a few ca re­
f ul brake applications.
- Driv ing for an extended period of time on
salt-covered roads w ithout using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­ ed. Otherwise the brake system could
overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­
c reased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­
est Aud i dea ler o r q ualified workshop.
- Never let the vehicle roll to a stop w ith
the engine shu t off.
- If the brake booster is not work ing, the
brake pedal must be pressed conside ra­
bly harder to make up for the lac k of
booster assistance.

Driving with your
quattro
App lies to veh icl es: w ith all-w hee l drive
With all-wheel drive, all four wheels are driv­
en.
General information
Wi th a ll W heel Drive, power is distributed to
all four wheels . This happens automatically
depending on your driving style and the road
conditions at the time . See also
~ page 196.
With the sport different ia l* , power distribu­
tion to the rear wheels is variable and can be
adjusted with Audi dr ive select*
~ page 102.
Always read and follow safety precautions
~ .&. .
Winter tires
When dr iving in the winter, yo ur vehicle with
all-wheel drive has an advantage, even wit h
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing: these tires must be moun ted o n
all four
wh eel s.

Catalytic converter
Applies to vehicles: with gasoline engine
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
... Always use lead-free gasoline c::> page 218,
Fuel supply .
... Never run the tank down all the way to emp­
ty .
... Never put too much motor oil in your engine
c::> page 232, Adding engine oil .,. Never try to push-or tow-start your veh icle.
The catalytic converter is an eff icient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is cr it ically
i mportant for the life of the cata lytic convert­
e r and proper functioning of the engine.
& WARNING ,~
T he temperature of the exhaust system is
high, both when driving and after stopping
the engine .
- Never touch the exha ust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
(D Note
- Be aware that just one tank f illing with
leaded fuel will already seriously de-
grade the performance of the catalytic
conve rter.
Dri vin g and en vironm ent 205
-Do not exceed the correct engine oil level
c::>page 232.
-Do not drive until the fue l tank becomes
completely empty. The engine cou ld mis­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is mov ing .
- Do not continue to operate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result i n overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have you r vehicle main tained properly
and in accordance w ith the se rv ice rec­
ommendations in your Warranty & Maintenance book let.
- Lack of proper maintenance as we ll as
improper use of t he vehicle wi ll impair
the function of the emission cont ro l
system and could lead to damage.
@) For the sake of the env ironment
Even when the Emission Control System is
ope rat ing properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank with lead-free s uper
g rade gasoline.
Diesel particulate filter
App lies to vehicles: wit h diese l eng ine
The diesel part iculate filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil­
te r clea ns itself automat ica lly unde r no rma l
driv ing cond itions. If the filter cannot clean it ­
self (for example, because you are on ly driving
sho rt distances), the filter becomes clogged
with soot and the

206 Driving and en vir onm ent
8_ WARNING
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in
the exhaust system area or a fire could start.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especia lly true for vehicles with low­
slung chassis (sports chassis)* and fully load­
ed vehicles.
Driving through water
on roads
Note the following to avoid vehicle damage
when dr iving through water, for example on
flooded roads:
- The water must not be any higher than the bottom of the vehicle body.
- Do not drive faster than wa lking speed.
8_ WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes f irst by brak ing carefully to re­
sto re the full braking effect.
(D Note
- Vehicle components such as the engine,
transmission, suspension or electrical
system can be severely damaged by driv­
ing through water.
- Always switch off the Start-Stop-System
when driving through water~
page 81.
-
(D Tips
-Check the depth of the water before d riv­
ing through it .
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving through salt water because
it can cause corrosion.
Shutting down vehicle
If you would like your vehicle to remain inop­
erative for a longer period of time, contact an
Audi or other specialized dealer. They can ad­
vise you on necessary precautions e .g. corro ­
sion prevention, maintenance and storage .
Pay attention to additional information con­
cern ing the battery. Refer to
~ page 238.
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, env ironmental impact, and
wear on your eng ine , brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumption by 10-15 percent . This sec­
tion will give you some tips on how you can
help the environment and your pocketbook.

@ Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, wh ic h will vary depend ing upon vehi­
cle load and speed, road and weather con­
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
~ Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
celerating . If you anticipate what is go ing to
h appen next, you will need to b rake less and,
thus, accelerate less. Let the vehicle coast
wheneve r poss ible -fo r example when you see
that the nex t tr affic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
~ T ry and keep well below your car's max imum
speed.
Accelerating gent ly reduces fuel consump­
tion, engine wear, and does not dist urb the
environment.
Fuel consumption, exhaust emissions and en­
g ine no ise increase d ispropo rtionately at high
speeds. If you dr ive at approxima tely three
q uarters of top speed, fue l consumption will
be red uced by one ha lf. Never dr ive faste r
than the posted speed limit and wea ther con­
d itions permit.
Reducing unnecessary idling
E ven when your car is just idling it burns up
fuel.
~ S hu t the engine off when you a re not dr iv ing
t h e vehi cle.
Dri vin g and en vironm ent 207
~ Do not warm up the vehicle by lett ing the
engine run at id le .
T he id ling phase is au toma tic ally red uced for
vehicles with the Start/S top system . It is eff i­
cient to switch off the engine in vehicles with­
out the Start-Stop-System when stopped at
railroad crossings and long red lights. Turning
the engine off for just 30-40 seconds saves more fuel than is burned by start ing the en-
. . gme again .
It takes a long t ime for the engine to warm up
fully when it is run ning at id le. However, wear
and noxious emissions are especia lly high
when the eng ine is warm ing up. So you should
dr ive away as soon as you start the engine and
avo id running at high rpms whi le the engine is
sti ll warming up.
(L} Note
Do not leave eng ine idling unattended af­
ter start ing.
If wa rni ng lights sho uld come
o n t o indi cate improper ope rat ion, t hey
wo uld go unheeded. Extended idlin g also
produces heat, wh ich could res ult in ove r­
heating or other damage to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
~ Have your ve hicle servi ced at reg ular i nter-
vals .
By havi ng your ve hicle regu la rly se rviced by an
Audi dealer he lps to ensu re tha t it ru ns prop­
erly and economically . The condition of your
vehicle not on ly affects its safety and ability to
ho ld its va lue, it a lso affects
fuel consump­
tion .
Check your oil each t ime y ou fill your tank.
The amou nt of o il used is re lated to engine
l oad and speed.
It is normal for the oil consumption of a new
engine to reac h its lowest value after a certa in
mileage has been d riven. .,..

220 Fuel supply and filling your fuel tank
Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fue l filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No. 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter. It is also norma l when whitish-blue
smoke comes out of the tailpipe after starting
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine idle unnecessari ­
ly after a cold start. Driving off slowly will
shorten the warm-up period.
A WARNING
- Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in ser ious engine damage and per­
sonal injur y.
- Never use fuel line anti-freeze offered for
gasoline engines.
(D Note
- Your Diesel engine has been specifically designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasoline. The
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
cause expensive engine repairs and will
also adversely affect your New Vehicle
Limited Warranty.
- If Diesel fuel sho uld get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not allow D iesel fuel to remain on connect­
ing hoses . They may develop leaks and
cause serious damage.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system shou ld fail, you
can still open the flap manua lly -for detailed
instructions see
¢ page 223.
You can find the fuel tank capacity of your ve­
hicle in
¢ page 283.
The label on the inside of the fuel filler flap
te lls you the correct fuel for your vehicle. For
more information about fuel specifications,
see
¢ page 218.
Your vehicle fuel tank has an on board refuel­
ling vapo r recovery system. This feature helps
to prevent fue l vapors from escaping from the
tank and polluting the environment while you refuel your vehicle. In order to fi ll the tank
proper ly while protecting the environment,
please fo llow this refueling procedure careful­
ly.
A WARNING
-Under normal operating conditions, never
carry addit ional fuel conta iners in your car .
Gas canisters and other conta iners used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision.
If you must
transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al ­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the ..,.

228 Check ing and filling
- Always disconnect the battery.
- Never smoke or wor k near heaters or
open flames . Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­

Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting specifi­
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can r un
smooth ly and reliably. Choosing the right o il
and changing oil within the t ime and mileage
intervals p rin ted in you r vehicle's Wa rranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has deve loped
a specia l quality sta ndard for engine oil that
will help assure that your vehicle's engine will
get the lubrication it needs for proper opera­
tion.

230 Check ing and filling
Mo dern engine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils, making them a smart choice
for use throughout the life of your Audi .
Whether you use synthetic or petroleum ­
based engine oil, the oil that you use must
conform to Audi 's oil quality standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (veh icles with diesel engine) to
he lp keep your vehicle's eng ine running
smoothly and help prevent the fo rmation of
harmf ul depos its , somet imes ca lled "sludge,"
that over t ime can lead to expensive repairs.
At the time of printing , engine oils availab le in
the U .S . and Canada that meet the exacting
specifi cations of A udi oi l st andard VW 502 00
(vehicles wi th gasoline engine) or VW 507 00
(vehicles with diesel engine) are synthetic en­
gine oils . This does not mean, however, that
every synthetic engine oil will meet Aud i oil
standard VW 502 00 (vehicles with gaso line
engine ) or VW 507 00 (veh icles w it h diese l
engine). So always be sure that you use an ap ­
proved oil.
To help prevent the format ion of harmful de­
posi ts use only oi l with the fo llow ing spec ifi­
cations printed on the oil containe r:
- Aud i oil standard VW 50 2 00 (ga soline en ­
gine )
- Audi oil sta nd ard VW 50 7 00 (diesel en -
gine )
Oil container labe ls may carry the specif ica ­
tion s ingly or i n comb ination with other desig­
nations and oil q ua lity standards.
Visco sity
Eng ine oi ls are graded according to thei r vis­
cosity. The prope r viscosity grade oil for your
engine depends on climac tic or seasonal con­
d itions whe re you drive. You can use oi l w ith a
viscosity g rade of SAE 5W40 across all tem ­
perat ure ranges for normal driving conditions .
H oweve r, if eng ine o il viscos ity grade
SAE 5W40 is not av ailable, you can a lso use viscosity grade SAE 5W-30 or SA
E OW-40 as
l ong as it meets Audi oil quality standard
VW 502 00 (veh icles with gasoline engine) or
VW 507 00 (vehicles with d iesel eng ine) spec­
ifications.
Beca use engine oi l that meets the Audi oil
standard may not be availab le everywhere
when you need it, we strong ly recommend
that you a lways carry with you an ex tra qua rt
( li ter) of oil that express ly conforms to the
VW 502 00 (veh icles with gasoline engine) or
VW 507 00 (vehicles w ith d iese l eng ine) spec­
ifica tion , in case you have to top off the oil
wh ile on t he road.
Applies to vehicle s with gasoline engine on­
l y:
Only if the level of the o il is at or be low the
min imum ma rk on the o il dipstick - and no oi l
t h at expressly conforms to A udi o il standard
VW 502 00 spec ificat ions is available -may
yo u top off with a high quality engine oi l, pre f­
erab ly synthetic-based, that meets ACEA A3
or AP I SM spec ificat ions, but even then, only
in v iscosity grades SAE 5W-40, SAE 5W-30, or
SAE OW-40. However, during the ent ire time
betwee n oil change intervals, never top off
with more than a total of 0 .5 qt/liter engine
o il that does not conform to Audi o il specifica­
t ion VW 502 00.
Applies to vehicle s with die sel engin e only:
Only if the level of the oil is at or below the

t h at expressly conforms to Audi o il standard
VW 507 00 spec ificat ions is available -may
you top off with a high quality engine oil, that meets ACEA C3 or API CF specifications, but
even then , on ly in viscosity grades SAE
5W-40, SAE 5W-30, or SA E OW-40 . However,
during the entire time between o il change in­
