12 Instrum ent s and indicator lamp s
Fuel level
The display@ Q page 10, fig. 3 only works
when the ignition is sw itched on . When the
d isplay has reached the reserve mark, the bot­
tom LED wi ll turn red and the
tD indicator
light turns on
Q page 24 . The bottom LED
blinks red when the fue l level is very low .
The on -board computer shows the range
based on the fuel leve l
Q page 2 8, On-board
computer display.
F or the tank capac ity in yo ur vehicle , refer to
the Tec hnical Data
Q page 288.
CJ) Note
Never d rive until the tank is completely
empty. The irregular supp ly of fuel that re­
sults from that can cause the engine to
misfire. Uncombusted f uel will then enter
the exha ust system. This can cause over­
heating and damage to the catalytic con­
verter .
Coolant temperature indicator
In vehicles without a coolant temperature in­
d icator , an indicator l ight . will turn on
when the coolant temperature is too h igh
Q page 20. Refer to Q Q) .
The coolant temperature ind icator @
c::> page 10, fig . 3 only works when the ignition
is switched on . T o prevent engine damage, ob­
serve the fo llow ing notes about the tempe ra­
ture ranges.
Cold range
If only the LEDs at the bottom of the gauge
turn on, the engine has not reached operat ing
temperature yet . Avoid high engine speeds,
fu ll acce le rat ing and heavy engine loads.
Norm al range
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving condi­
tions. The L EDs higher up may turn on if the
engine is under heavy load or the o uts ide tern- perature is h
igh. This is not a cause for con­
cern as long as th e . indicator light in the
display does not turn on.
Hot range
If the L EDs in the upper area of the disp lay
and the. indicator light in the instrument
cluster disp lay t urn on , the coo lant tempera ­
ture is too high
c::> page 20.
A WARNING
I-
- Always observe the warn ing in
c::> page 217, before opening the hood
and checking the engine coolant level.
- Never open the eng ine hood if you see or
hear steam, or if you see engine coo lant
dripping from the engine compartment.
You could burn yourse lf . Let the engine
coo l off f irst unti l yo u can no longe r see
or hea r steam or coolan t escap ing.
Q) Note
- In vehicles w ith a boost pressure indica­
to r*, this indicator replaces the tempe ra­
t ur e display. To promote a long engine
service life, avoiding h igh engine speeds,
full acceleration and he avy eng ine lo ads
during approximately the first 15 m i­
nutes when the engine is co ld is recom ­
mended. The amount of time until the
eng ine is warm depends on the outside
temperat ure. Check the engine oil tem­
perature* if necessary.
c::> page 32
- Add itiona l head lights and other compo­
nents in front of the air intake impairs
the cooling effect of t he coolant. This in­
creases the risk of the engine overheat­
ing during high outs ide temperatures
and heavy eng ine load.
- T he front spoiler also he lps to d istr ibute
cooling ai r correctly wh ile driving. If the
spoiler is damaged, the coo ling effect
w ill be imp aired and the risk of the en­
gine overhea ting will increase . See an au­
thorized Audi dealer or autho rized Audi
