open hood AUDI S8 2008 Owners Manual

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.
<£> For the sake of the environment
Upshifting early saves fuel and reduces engine noise.•
Digital clock with date display
Date and time of day can be set in MM/.

vehicle is sensed by the system.
How is the anti-theft alarm system switched on?
The anti-theft alarm system is switched on when you lock the
vehicle. The system is activated approximately 30 seconds after the
vehicle is locked . The indicator lights on top of the driver's and front
passenger's door trim start flashing rapidly for 30 seconds and then
blink slowly.

When the vehicle is locked, the alarm system monitors and protects
the following parts of the vehicle:
• engine compartment
• luggage compartment
• doors
• ignition
When the system is activated, the alarm will be triggered if one of

0 Note
• Never try to remove dirt, mud or dust if the surface of the vehicle
is dry. Never use a dry cloth or sponge, since this could scratch your
vehicle 's paint or windows.
• Never wash your car in bright sunlight. Drops of water act as
magnifying lenses and may damage your paint.
• When you wash your car in the winter: if you rinse your vehicle
wi th a hose, be ca reful not to aim the stream of wa ter direc tly at
locks, or at door or hatch openings -they can freeze shut.
• Never use sponges designed to remove insects, or any kitchen
scouring sponges or similar products. They can damage your paint
finish .
• Never use a dry cloth or sponge to clean the headlights. Only use
wet cloths or sponges to prevent sc ratches . It is best to use soapy
water .
~ For the sake of the environment
In the interest of the environment, the vehicle should only be
washed in special wash bays. •
Washing your vehicle with a power washer
Cleaning the exterior of your car with a high-pressure
power washer is safe as long as you observe a few simple
rules.
- Before using the power washer, make sure you have read
and understood the WARNINGS :::>
& in "General infor­
mation" on
page 288.
- Always follow the operating instructions for the power
washer. - Make
sure that the jet on the spray hose produces a "fan
shaped spray".
- Do
not hold the spray nozzle too close to soft materials.
When cleaning the vehicle w ith a power washer always follow the
operating instructions. This applies particularly to the
operating
pressure
and the spraying distance. Maintain a sufficient distance
to soft materials such as rubber hoses and sound/vibration dead ­
ening materials (particularly on the underside of the engine hood).
Do not use a jet which sprays water in a
direct stream or one that
has a
rotating jet.
Water temperature should no t exceed 140 °F (60 °Cl.
& WARNING
Never wash tires with a jet that sprays water in a direct stream.
This could cause invisible damage to the tires and weaken them,
even if the spray is from a relatively long distance and for a short
time. Damaged and weakened tires can fail and cause accidents
and personal injury .
0 Note
To avoid damaging your vehicle, always make sure that there is
sufficient distance between the spray head and soft materials like
rubber hoses, plastic parts and sound-deadening materials . Never
aim the spray head at the same point for a long time. This also
applies to cleaning headlights and painted bumpers . Remember:
the closer the nozzle is to the surface of the material , the greater the
stress on the material. •

see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
