• Always observe the warnings in => page 265, "Engine compart­
ment", before opening the engine hood and checking the brake
fluid.
• Driving with low brake fluid is a safety hazard! Stop the car and
get professional assistance.
• If the brake system warning/indicator light illuminates
together with the ABS warning/indicator light, then the ABS
system is malfunctioning. The rear wheels could quickly lock up
when you apply the brakes. This could lead to loss of control and
your vehicle could slide! Drive carefully to the nearest authorized
Audi dealer and have the malfunction corrected. •
Engine cooling system malfunction -L
A malfunction in the engine cooling system must be
repaired as soon as possible.
When the - L symbol in the display flashes, then either the
engine coolant
temperature is too high, or the coolant level
is too low. In addition to the symbol, the following message
also appears in the display:
Switch off engine, check coolant level
- Pull off the road and stop the vehicle.
- Turn off the engine.

Driver information display
-Check coolant level :::> page 281.
-Add coolant if necessary=> page 282.
-Continue driving only after the engine coolant
warning/indicator light goes out.
-Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction.
I f the generator warning/indicator light should also illuminate
=> page 22, then the fan belt may be damaged.
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
=> page 79, "Emer­
gency flasher
A" .
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded .
Wait until you can no longer see or hear steam or coolant escaping.

the engine and allow it to cool. Follow the warning stickers
=> page 265, "Engine compartment" .
0 Note
Do not continue driving if the-~-symbol illuminates. It indicates a
cooling system malfunction likely to result in serious damage to the
engine. •
Engine oil pressure malfunction ~
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to result in serious damage to the
engine.
If the 9=::;,. symbol appears in the display and blinks, the oil
pressure is too low. In addition to the symbol, the following
message also appears in the display:
Switch off engine, check oil level
Immediate actions
-Pull off the road and stop the vehicle.
-Shut the engine down.
-Check the engine oil level with the dipstick=> page 277.
Dipstick reading checks too lovv
-Top off oil to the proper level => page 278.
-Make sure that the oil pressure warning symbol 9=::;f.
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
-If the 9=::;f. symbol starts flashing again even though the
engine oil level checks OK on the dipstick,
do not start
driving again and do not let the engine run at idle .
Instead, contact your authorized Audi dealer for assis-
tance.
.,_

[ i J Tips
• The engine oil pressure symbol ~ is not an indicator for a low
engine oil level. Do not rely on it . Instead , check the oil level in your
engine at regular interval s, preferably each time you refuel , and
always before going on a long trip.
• The yellow oil level warning indication requires oil refill or
workshop service without delay . Do not wait until the red oil pre s­
s ure warning symbol
~ starts to fla sh before you respond to the
low oil level warning
-... . By then , your engine may already have
s uffered serious damage. •

Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a
set speed limit.
Fig . 21 Disp lay : s pee d
wa rning syste m
.,.
irechnical data

Driver inf orma tion di spl ay
The speed warning system warns the driver if he exceeds a previ­
ously stored maximum speed . A warning tone wi ll sound as soon as
the vehic le speed exceeds the set speed by about 6 miles per hour
(10 km/h) . At the same time, a warning symbol appears in the
display~ fig. 21 .
The speed warning system has
t wo wa rning thre sholds that func ­
tion independent ly of each other and that have somewhat different
purposes:
Sp eed w arnin g 1 -
You can use speed warning 1 to set the maximum speed while you
are driving . This setting will remain in effect until you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol (USA models)/ (: (Canada models) in
the warning 1 disp lay appears when you exceed the maximum
speed. It goes out when the speed falls be low the stored maximum
speed .
The speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is de leted.
Setting speed warning 1
~ page 36 .
S pee d w arni ng 2
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a genera l maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
The speed warning 2 symbol, (USA models)/ (Canada models) appears in the disp lay when you exceed the stored speed limit .
Unlike warning 1, it wil l not go out until the vehicle speed drops
below the stored speed limit .
Setting speed warning 2
~ page 37.
[ i ] Tip s
Even though your vehicle is equipped with a speed warning system,
you shou ld still watch the speedometer to make sure you are not
driving faster than the speed l imit. •
