& WARNING
• Always observe the warnings in => page 242, "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

ment
Driver information display
Check coolant level ~ page 258.
-Add coolant if necessary~ page 259.
- 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.
If 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 82, "Emer­
gency flasher

• 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 compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn of
the engine and allow it to cool. Follow the warning stickers
=> page 242, "Engine compartment" .
0 Note
Do not continue driving if the -F-symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your

Driver information display
Engine oil pressure malfunction 9=7-
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to inflict severe damage to the engine.
If the ~ symbol appears in the display and blinks, the oil
pressure is too low. An additional driver message can also
be displayed by pressing the [CHECK] button:
Switch off engine and check oil level
Immediate actions
- Pull off the road.
- Stop the vehicle.
Turn off the engine.
- Check the engine oil level with the dipstick=> page 254.
Dipstick readings checks too low
-Top off oil to the proper level => page 255 .
- Make sure that the oil pressure warning symbol
~
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
- If the oil pressure warning symbol~ starts flashing
again even though the engine oil level checks
OK on the
dipstick,
do not continue driving and do not let the
engine run in idle.
Instead, contact your authorized Audi
dealer for assistance.
[ i ] Tips
• The engine oil pressure symbol 'l::::r. 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 intervals, 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 pres­
sure warning
'l::::r. starts to flash before you respond to the low oil
level warning . By then, your engine may already have suffered
serious damage. •

Speed warning system
Overview
The spee d warning system helps you to keep your driving
speed below a set speed limit.
Fig. 19 D ispl ay : s pee d
wa rning sy st em
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 vehicle speed exceeds the set speed by about 3 miles per hour (3 km/hl. At the same time, a warning symbo l appears in the display
~fig.19.
The speed warning system has
two warning thre sh old s that func­
tion independently of each other and that have somewhat different
purposes :
Speed warning 1
You can use speed warning 1 to set the maximum speed while you
are driving . This setting will remain in effect un til you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol
C-~ (USA models)/ (Canada models) in
the warning 1 display appears when you exceed the maximum speed . It goes out when the speed falls below the stored maximum
speed. .,
~ehicle care Technical data

Driver inf orma tion d ispl ay
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 .
Speed warning 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 general 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 will not go out until the vehicle speed drops
below the stored speed limit.

[ i ) Tip s
Even though your vehicle is equipped with a speed warning system,
you should still watch the speedometer to make sure you are not
driving faster than the speed limit .•

Driver information display
symbols appear in the instrument cluster display to alert the driver.
The warning light in the instrument cluster comes on when the
tire is significantly underinflated .
The warning light _, also lights up during a system failure.
When the wheel is turning, the system receives radio signals from
sensors located inside each tire .
A factory spare wheel is delivered with sensor. However, the spare
wheel is not checked by the tire pressure monitoring system. Such monitoring can only occur after the spare wheel has been installed
and initialized ~
page 45.
Be aware that tire pressure is also dependent on the temperature of
the tire. For every 18 °F (10 °C) increase in tire temperature, tire pres­
sure increases by about 1.5 psi (0.1 bar). The tire warms up while the
vehicle is moving and tire pressure rises. So you should adjust tire
pressure only when they are
cold, when tire temperature is roughly
the same as ambient air temperature.
In order to keep the tire pressure monitoring system properly cali­
brated, tire pressure on all four tires should be checked at regular
intervals, adjusted if necessary and saved in the proper setting
(recommended pressure)~
page 43.
The tire pressure is shown on the tire pressure label. On USA vehi ­
cles, the tire pressure label is located on the driver's side B-pillar. On
Canada vehicles, the tire pressure label is located either on the
driver's side B-pillar or inside the fuel filler flap. The tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured . For recommended tire
pressures for normal load conditions, please see chapter
~ page 277.
& WARNING
• When the tire pressure monitoring system warning light is lit,
one or more of your tires is significantly under -inflated. You should
stop and check your tires as soon as possible, and inflate them to
& WARNING (continued)
the proper pressure as indicated on the vehicle's tire pressure
label
~ page 271. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure. Under-infla­
tion also is likely to impair the vehicle's handling and stopping ability .
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
For the sake of the environment
Driving with under-inflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire should be checked monthly when cold and set to the
recommended inflation pressure as specified on the tire pressure
table~
page 277 .
• The tire pressure monitoring system helps the driver to keep
track of the tire pressures . But the driver still has the responsibility
for maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves must not be
detached or exchanged. Only the valve core needs to be replaced
and, if necessary, the valve and the wheel electronics replaced.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your Audi
dealer. .,
