2010 AUDI S3 coolant level

Instruments and warning/indicator lights
Engine cold
As long as the needle remains at the left end of the gauge, the
engine still has not reached its operating temperature . Avoid high
engine speeds, heavy engine loads and heavy throttle.
Normal temperature
When the engine has reached its operating temperature, the needle
will move into the middle of the gauge and remain there. If the engine is working hard at high outside temperatures, the needle
may turn further to the right. This is no cause for concern as long as
the
_ f_ warning light in the instrument cluster does not illuminate.
When the
-L warning light starts to flash, this can mean one of two
things: either the coolant
temperature is too high, or the coolant
level is too low=> page 30.
& WARNING
• Always observe the warning in=> page 215, "Engine compart ­
ment" before opening the engine 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. •
Fuel gauge
The fuel gauge works only when the ignition is on.
When the needle reaches the red area, the warning light in the
instrument cluster will illuminate=>
page 32 I). This means you
have approximately 1.8 gallons (7 liters) of fuel left in the tank.
Time
to refuel!
The total tank capacity of your vehicle is listed in=> page 296,
"Data".
0 Note
Never run the tank completely dry! An irregular supply of fuel can
cause engine misfiring and fuel could enter into the exhaust
system. The catalytic converter could then overheat and be
damaged .•
Speedometer with odometer
The speedometer shows you the vehicle speed, and the
odometer shows you how many miles (kilometers) you
have driven.

Brake system malfunction
BRAKE (USA models) /((D) (Canada models )
The indicator light flashes if the brake fluid level is too
low, if there is a malfunction in the ABS system or when
the parking brake is engaged.
If the BRA KE/(CD) symbol flashes in the display with the
parking brake released, there is a malfunction in the brake
system. In addition to the symbol, one of two messages
appears in the display:

Checking and filling -
---------------------=----"=---------
0 Note
• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of
coolant additive to 60%.
• When adding coolant additive to your cooling system,
remember:
-We recommend using only coolant additive G12+ + (check the
label) for your vehicle. This coolant additive is available at autho­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection . The resulting corrosion can cause a
loss of coolant and serious engine damage .
• Do not add any type of radiator leak sealant to your vehicle's
engine coolant. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and cou ld result
in damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.
Fig . 169 Engine
compartment : coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 224.
Turn off the ignition .
Read the engine coolant level from the coolant expan­
sion tank==> fig. 169. With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
" max" marking .
The location of the coolant expansion tank can be seen in the
engine compartment illustration=>
page 225.
To obtain an accurate reading, the engine must be switched off .
The expansion tank in your vehicle is equipped with an electric
coolant level sensor.
When the coolant level is too low, the warning light in the Auto­
Check System =>
page 30will blink until you add coolant and the
level has been restored to normal. Even though there is an electric
coolant level sensor, we still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event
of coolant loss, the cooling system should be inspected immedi­
ately by your authorized Audi dealer. It is not enough merely to add
coolant.
In a
sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating.
0 Note
Do not add any type of radiator leak sea lant to your vehicle's engine
coolant. Adding radiator repair fluid may adversely affect the tune- _..
