reached the reserve mark, the bottom LED will
turn red and the
ljJ indicator light turns on
¢
page 23. The bottom LED blinks red when
the fuel level is very low.
The on-board computer shows the range based
on the fuel level¢
page 28, On-board comput­
er display.
For the tank capacity in your vehicle, refer to the
Technical Data
¢ page 260.
(D Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter.
Coolant temperature indicator
In vehicles without a coolant temperature indica­
tor, an indicator light. will turn on when the
coolant temperature is too high ¢
page 19. Re­
fer to ¢(1) .
The coolant temperature indicator @c:>
page 10,
fig . 3 only works when the ignition is switched
on . To prevent engine damage, please observe
the following notes about the temperature rang­
es.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­ perature yet. Avoid high engine speeds, full accel­
erating and heavy engine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions . The
LEDs higher up may turn on if the engine is under
heavy load or the outside temperature is high.
This is no cause for concern as long as the. in­
dicator light in the instrument cluster does not
turn on.
12
Hot range
If the LEDs in the upper area of the display and
the . indicator light in the instrument cluster
display turn on, the coolant temperature is too
high
c:> page 19 .
A WARNING
-Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. Wait until you no longer see or hear
steam or coolant escaping.
- The engine compartment in any vehicle can
be a dangerous area . Stop the engine and al­
low it to cool before working in the engine
compartment. Always follow the informa­
tion found in ¢
page 198, Working in the
engine compartment.
(D Note
- In vehicles with a boost pressure indicator* ,
this indicator replaces the temperature dis­
play. To promote a long engine service life,
avoiding high engine speeds, full accelera­
tion and heavy engine loads during approxi­
mately the first 15 minutes when the en­
gine is cold is recommended . The amount of
time until the engine is warm depends on
the outside temperature . Check the engine
oil temperature* if necessary .
c:> page 30
-Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy engine
load.
- The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance.

@ Tips
Diesel engines: Due to the high efficiency of
these engines, the engine may not a lways
reach operating temperature in cold outside
temperatures. This is normal and not a cause
for concern.
