clock 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.•

Vehicle care Do-it-yourself service Technical data

The label on the inside of the fuel filler flap tells you the correct fuel
for your vehicle . For more information about fuel specifications, see
=> page 301.
Your vehicle fuel tank has an onboard refuelling vapor recovery
system. This feature helps to prevent fuel vapors from escaping
from the tank and polluting the environment while you refuel your
vehicle. In order to fill the tank properly while protecting the envi­
ronment, please follow this refueling procedure carefully.
& WARNING
Under normal operating conditions , never carry additional fuel
containers in your car. Gas canisters and other containers used to
transport fuel can be dangerous . Such containers , 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 always observe local and state laws regarding the use, trans ­
portation and storage of such fuel containers. Make certain the
container meets industry standards (ANSI/ASTM F852 -861.
0 Note
Never drive your vehicle until the fuel tank is completely empty. The
irregular supp ly of fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic converter. •

Fuel supply and filling your fuel tank
Refuelling procedure
- Insert the fuel nozzle from the gasoline pump into the
fuel filler neck as far as it will go.
- Select a medium refuelling rate so that the nozzle switches off automatically when the tank is full.
Putting the fuel cap back on
-After filling your tank, twist the fuel filler cap clockwise
until you hear a definite click.
- Close the fuel filler flap.
To avoid fuel spilling or evaporating from the fuel tank always close
fuel filler cap properly and completely. An improperly closed fuel
filler cap may also cause the MIL
lamp=> page 27 to come on.
& WARNING
Improper refueling or handling of fuel can cause fire, explosion
and severe burns.
• Fuel is highly flammable and can cause severe burns and other
injuries.
• Failure to shut the engine off while refueling and/or to insert
the pump nozzle fully into the fuel filler neck could cause fuel to spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire.
• Never use a cellular telephone while refueling. The electromag­
netic radiation can cause sparks that can ignite fuel vapors and
cause a fire.
• Never get back into your vehicle while refueling. If in excep ­
tional circumstances you must get back in your vehicle while refu­
eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
Static electricity can cause sparks that can ignite fuel vapors
released during refueling .
& WARNING (continued)
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel container.
• For your safety, we strongly recommend that you do not travel
with a portable fuel container in your vehicle. The container, full or
empty may leak and could cause a fire, especially in a crash.
• If, under exceptional circumstances, you must transport a
portable fuel container, please observe the following:
-Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example, in the luggage compartment, or on
the trunk). Static electricity can build up while filling and can
ignite fuel vapors causing a fire.
- Always place a portable fuel container on the ground before
filling.
- Always keep the filler nozzle completely inside the portable
container before and during filling.
- If filling a portable container made of metal, the filler nozzle
must always be in contact with the container. This will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment. Fuel vapors are highly flammable .
- Always observe local and state/provincial laws regarding the
use, storage and transportation of fuel containers.
- Make certain the fuel container meets industry standards
(ANSI / ASTM F852-86).
0 Note
If any fuel has spilled onto the car, it should be removed immedi-
ately to prevent damage to the paint.
