tips, suggestions and warnings for using your ve­ h icle.
Keep this manua l in yo ur vehicle at all times. This
is especially important if yo u loan your vehicle to
others or sell it.
This owner's manua l describes the
equipment
rang e
specified for this mode l at the time of
printing. Individual equipment options described
may on ly be available at a later date or may on ly
be offered in certain countries.
Some se ct ions in this manua l do not apply to all
vehicles. When this is the case, the beginning o f
the section indicates the
va lidity , for example
"Applies to veh icles: with auxiliary heat ing" . Op ­
tional or vehicle-spec ific equ ipment is a lso identi ­

Instruments and indicator lights
(+S °C), a snowflake symbol appears in front of
the temperature display.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed may
be slightly higher than the actual temperature
outside due to the heat radiating from the en­
gine.
A WARNING
Do not assume the roads are free of ice based
on the outside temperature display . Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+S
0
()
and that ice can increase the risk of accidents .
@ Tips
You can change the measurement units, for
example for temperature or speed, in the
MMI.
Fuel level
The display @ q page 10, fig. 3 only works when
the ignition is switched on. When the display has reached the reserve mark, the bottom LED will
turn red and the
tj] indicator light turns on
q page 24. Th e bottom LED blinks red when
the fuel level is very low.
The on-board computer shows the range based
on the fuel level~
page 29, On-board comput­
er display.
For the tank capacity in your vehicle , refer to the
Technical Data
qpoge 303.
(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
t or, an indicator light . will turn on when the
12
coolant temperature is too high q page 20. Re­
fer to
q 0 .
The coolant temperature indicator @ q 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 ac­
ce lerating 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.
T his is no cause for concern as long as the. in­
dicator light in the instrument cluster does not
turn on.
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
q page 20 .
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
allow it to cool before working in the engine
compartment. Always follow the informa­
tion found in¢
page 236, Working in the
engine comportment.
([) 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

acceleration and heavy engine loads during
approximately the first 15 minutes when
the engine is cold is recommended. The
amount of time until the engine is warm de­
pends on the outside temperature. Check
the engine oil temperature* if necessary
¢ page 32.
-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 en­
gine load.
- The front spoiler also he lps to distr ibute
cooling air correct ly wh ile driving. If the
spo iler 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 always
reach operating temperature in cold outside
temperatures. This is normal and not a cause
for concern.

Overview
Some indicator lights turn on briefly as a funct ion
check when you sw itch the ignition on. These sys­
tems are marked with a./ in the following tab les.
If one of these ind icator lights does not turn on,
there is a malfunction in that system .
Your vehicle has either a monochrome display or
