The needles in the instrument cluster are illu­
minated when the ignition is switched on. The
gauges are also illuminated when the lights
are turned on . The instrument illum inat ion
dims automatically as the amount of light
outside decreases. This helps to remind the
driver to turn the headlights on as it becomes
darker outside.

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.

Read an d follo wing the WARNINGS before
checking anything in the engine compartment
r::;,page 198.
Checking the engine coolant level
.. Park your vehicle on a level surface.
.. switch the ignition off.
.. Read the coolant level on the coolant expansion
tank
r::;, fig . 162 . The coolant level must be be ­
tween the mark ings when the engine in cold .
When the engine is warm it can be slightly
above the upper marking .
Adding coolant
Requirement: there must be a residual amount of
coolant in the expans ion tank
c> Q).
.. Let the engine cool down.
.. Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
<=>& .
.,. Add coolant mixed in the correct ratio
r::;, page 205 up to the upper marking .
.. Make sure that the fluid level rema ins stable.
Add more coolant if necessary.
.. Close the cap secure ly.
A coolant loss s uggests a leak. Immediate ly drive
your veh icle to an authorized A udi dealer or au­
thor ized Audi Service Facility and have the cool­
ing system inspected.
If the cooling system is not
leaking, a loss can come from the coolant boiling
206
thro ugh ove rheating and being pushed out o f the
cooling system.
A WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
w ith the engine hot. There is a risk of burns .
- Stop the eng ine and a llow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coo lant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the e x­
haust system or hot engine components.
The ethy lene glycol in engine coola nt can
catch fire under certa in circumstances.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the o riginal container
away from ch ildren . The re is a risk of poison­
ing .
- W hen working in the engine compartment,
remember that the rad iator fa n can switch
on ev en if the ignition is switched off, wh ich
increases the risk of pe rsonal injury.
@ Note
Do not add coolant if the expans ion tank is
empty . Air cou ld enter the cooling system and
damage the eng ine. If this is the case, do not
continue driving. See an author ized Audi deal ­
er or a uth ori zed Audi Service Facility for a ssis­
ta nce .
. Radiator fan
The radiator fan switches on automatically by it­
self
An a uxiliary electric radiato r fan switches on and
off depending on coolan t temperature and other
vehicle ope rat ing cond itions .
After yo u sw itch the engine off, the aux ilia ry fan
can continue running for up to 10 m inutes -even .,,.

with the ignition off. It can even switch on again
l ater by itself~.& , if
- the temperature of the engine coolant rises due to the heat bui ld-up from the eng ine in the en ­
gine compartment, or
- the engine compar tment heats up because the
vehicle is parked in intense sunlight.
A WARNING , --
- To reduce the risk of personal injury never
touch the radiator fan.
- The auxiliary e lectric fan is temperature con­
trolled and can switch on suddenly even
when the engine is not running.
- The aux iliary radiator fan switches on auto­
matically when the engine coo lant reaches a
certain temperature and will continue to run
until the coolant temperature drops.

ate the vehicle . The comp lete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified fac ility and the
cause corrected . If the brake flu id level is too low,
the brake warning/indicator light wi ll illuminate .
Contact an a uthorized Audi dea ler
immedi ate ly .
Changing brake fluid
Have the brake fluid changed by an experienced
technician.
Brake fluid absorbs moisture from the air. If the
water content in the brake flu id is too hig h, cor­
ros ion in the brake system may result after a per i­
od of t ime. The bo iling po int of the brake fluid
will a lso decrease cons iderab ly and decrease
braking performance.
Therefore, the brake fluid must be changed
e ve ry
tw o years .
Always use new brake flu id which co n­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4".
The brake fluid reservoir can be diff icu lt to reach,
therefore, we recommend tha t you have the
brake flu id changed by you r authorized
Audi
de aler.
Your dea le r has the correct tools, the
right brake fluid and the know-how to do this for
you .
A WARNING
- -
-Brake flu id is poisonous. It must be stored
only in the closed original conta iner out of
the reach of children !
- Brake failure can resu lt from o ld or inappro­
priate brake fluid. Observe these precau­
tions:
- Use only brake fluid that meets SA E spe ci­
