2008 AUDI S8 oil temperature

If the indicator goes all the way to the right side inside the coolant
temperature gauge, then the engine coolant temperature is too
high.
Pull off the road to safe location, turn off the engine and let it
cool down.
If the warning light comes on again after you have driven
a short distance, contact a qualified workshop.
& WARNING
• Always observe the warning in :::::, page 299, "Engine compart­
ment", 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 dripping 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.
0 Note
• Mounting additional lights or accessories in front of the air inlets
reduces the cooling effect of the radiator. At high outside tempera ­
tures or high engine load, the engine could overheat.
• The front spoiler has been designed to properly distribute the
cooling air when the vehicle is moving . If the spoiler is damaged,
this could reduce the cooling effect and the engine could then over­
heat. Ask your authorized Audi dealer for assistance. •
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revolutions per
minutes).
The tachometer 0:::::, page 12, fig. 2 is the left of the two large clock­
type displays.
The engine turns at a speed
1,000 times the single digit in the
display, e.g. if the needle is pointing at the "2" the engine is turning
at 2,000 RPM.
Controls and equip­ ment
Instruments and warning/indicator lights
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
permissible engine RPM after the break-in period . Before reaching
this area, move the selector lever to position "D (Drive)" or ease your
foot off the accelerator pedal.
0 Note
The tachometer needle should not move into the red range . If it
does, then only for a very short period of time. You could damage
your engine by driving at high RPM.

P position.
- Switch off the engine and remove the ignition key from
the ignition lock.
& WARNING
This is how you can reduce the risk of injury when leaving your
vehicle.
Controls and equip­ ment
&, WARNING (continued)
• Never park the vehicle where it can come in contact with dry
grass, spilled fuel or any other flammable materials.
• When parking on hills, always turn the wheels so that the front
wheels will first roll into the curb, if the vehicle should start to roll.
• Never allow anyone -especially small children -to remain
in the
vehicle when it is locked. Locked doors make it more difficult for
rescuers to access the passenger compartment in the event of an
emergency. Danger to life!
• Never leave children unsupervised in the vehicle. Children
could release the parking brake or move the gearshift lever out of
gear. The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a parked
vehicle can reach dangerous levels.
0 Note
• Please exercise care when you park your vehicle in parking areas
with parking barriers or curbs . Parking barriers and curbs vary in
height and could damage your bumper and related components as
the front of your vehicle moves over a barrier or curb that is too high, as you park or as you back out of a parking spot. In order to be
sure that no such damage can occur, you may wish to stop short of
having the front tires of your car touch the parking barrier or curb.
• Please also exercise exceptional care when you drive up or down
steep ramps or drive over curbs or other obstacles, for which the
vehicle is not designed , because components of the vehicle close to
the ground, such as bumper covers, spoilers and suspension and
exhaust system components, may become damaged. •

to help keep your vehicle's engine running smoothly and help
prevent the formation of harmfu l deposits, sometimes called
"sludge, " that over time can lead to expensive repairs .
At the time of printing, engine oils available in the U.S. and Canada
that meet the exacting specificat ions of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oi l standard VW 502 00. So
a lways b e sur e that you use an approved oil.
To help prevent the formation of harmful deposits use only oi l with
the following specifications printed on the oil container :
Audi oil sta nda rd VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and oil quality standards.
V iscosi ty
Engine oi ls are graded according to their viscosity . The proper
viscosi ty grade oi l for your engin e depends on climactic or seasonal
conditions where you drive . You can use o il with a v iscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi­
tions.
However , if eng ine oil viscosity grade SAE 5W40 is not available, you
can a lso use viscosity grade SAE 5W -30 or SAE 0W -40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
B ecause engin e oil that meets the Audi oi l standard may not be
avai lable everywhere when you need it, we strongly recommend
that you a lways carry with you an extra quart !liter) of oil that
express ly conforms to t he VW 502 00 specification, in case you have
to top off the oil while on the road.
Only if th e level of the oil is at or be low the minimum mark on the
oi l dipstick -and no oil that express ly conforms to Audi oi l standard
VW 502 00 specifications is avai lable -may you top off with a high
quality engine oi l, preferably synthetic -based, that meets ACEA A3,
ACEA A5 or ACEA B5, API SL or ILSAC GF -3 specifications , but even
t hen, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40.
However, during the entire time betwe en oil change int erva ls, nev er top off with more than a total of 0
.5 qt/ liter engine oil that does not
conform to Audi oil specifica tion VW 502 00.
For more information about engine oil that has been approved for
your vehic le, please contact either your authorized Audi dealer or
Aud i Customer Relat ions at 1 (800) 822-2834 or v isit our web s ite at
www.audiusa.com or www.audicanada.ca. Here you will also find a
current list of o ils (manufacturers, brand names
etc.I that conform
to Audi oi l standard VW 502 00.
Ch an g in g t he en gin e oil
The engine oil and o il filter must be changed according to the
mileage (ki lometers) and time intervals specified in your vehic le 's
Warranty & Maintenance booklet . Do not exceed these intervals -
harmful deposits from old engin e oil can reduce engin e perfor­
mance and can lead to expensive eng ine repa irs.
Changing the oil at the recommended intervals is so very impor tant
because the lubricating properties of oi l decrease gradua lly during
normal vehicle use. If you are not sure when you have your o il
changed, ask your authorized Audi Service Advisor.
Under some circumstances the eng ine oil should even be changed
mor e frequen tly . Change oil more oft en if you drive most ly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and -go traffic conditions, or when you use your vehicle where
t emperatures stay be low freezing po int for long per iods .
Detergent add it ives in the oi l wi ll make fresh oil look dark after the
engine has be en running for a short time. This is normal and is not
a reason to change the oi l more often than recommended .
Dam age or malfun ction s du e to lack of m aint enan ce
It is essential that you change your oil at the recommended interva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover

Engine oil consumption
The engin e in your vehicle d ep ends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effect ive lubrication and cool ing of internal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumption varies from engine to eng ine
and may change significantly over the life of the engine . Typically,
eng ines wi th a specif ied break -in period
(see => page 2771 consume
more oil during the break -in period than they consume after oi l
consumption has stabi lized .
Under normal conditions, the rate of oil consumption depends on
the quality and viscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
co ndensation or fue l residue and the oxidation level of the o il. As
any engine is subject to wear as mileage builds up, the oil consump ­
t io n may increase over time until rep lacement of worn components
may become necessary .
With all these variables coming into play, no standard rate of oil consu mption can be estab lished or specified. T here is no a lternative
to regular and frequent checking of the oil level, see
Note .
If the yellow eng ine o il level warni ng symbol in the instrume nt
cluster ~ lights up, you should check the oil level as soon as
poss ible
with the oil dipstick => page 311 . Top off the oil at your
earliest
convenience=> page 312.
