workshop and have the malfunction correct­ed.
- If the brake warning/indicator light does
not go out after a few seconds and the park­
ing brake is released, or lights up while you
are driving, the fluid level in the brake fluid
reservoir is too low. If you believe that it is
safe to do so, proceed immediately at low
speed to the nearest authorized Audi dealer
or qualified repair facility and have the
brake system inspected.
- Always keep in mind that after several brake
applications, you will need greater pressure
on the brake pedal to stop your vehicle. Do
not rely on strained brakes to respond with
maximum stopping power in critical situa­
tions. You must allow for increased braking
distances. The extra distance used up by
fading brakes could lead to an accident.
PARK/( ®) Electromechanical parking brake
The warning/indicator light monitors the elec­
tromechanical parking broke.
If the indicator light- (USA models)/ .
(Canada models) turns on, the parking brake was
set .
- (USA models) • (Canada models) Cau­
tion: Vehicle parked too steep
If the indicator light blinks and the message ap­
pears, there is not enough braking power to keep
the vehicle from rolling. The brakes have over­
heated. The vehicle could roll away even on a
small incline.

- L Engine cooling system malfunction
A malfunction in the engine cooling system must
be repaired as soon as possible.
• Switch off engine and check coolant level
If the indicator light turns on and the message
appears, the coolant temperature is too high or
the coolant level is too low.

"' Contact your authorized Audi dealer for assis-
tance if necessary.
If the engine coolant level is correct, then the ra­
diator fan may be the cause of the malfunction.
• Coolant temperature too high! Please let en­
gine run with vehicle stationary
If the indicator light turns on and the message
appears, let the engine run at idle for a few mi­
nutes to cool down.

_& WARNING
-
-Never rely exclusively on the outside tem­

face is icy or not. Keep in mind that road sur­
faces, especially bridges and overpasses,
could be ice covered and slippery even at an
outside temperatu re above 4 1 °F (+S

().
- Always remember, even if the "snowflake"
symbol (ice warning) does not appear in the
d isp lay, black ice cou ld be on the road.
- Always reduce your speed and drive with
specia l care in cold weather cond itions when
the chance of encountering icy road surfaces
i n creases.
(0 Tips
- If the vehicle is stationary, or if you are driv­
ing at a very low speed, the temperature
shown in the display might be slight ly high­
er than the actual outside temperature. This
is caused by the heat being radi ated from
the engine . .,..

On Board Diagnostic
System (OBD}
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ifl in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system.
The warning/indicator light illuminates when the
ignit ion is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly.
If the light does not go out after the engine is
started, or illuminates while you are dr iving, a
28
malfunction may exist in the engine system. If
the light illum inates , the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid accelerations)
and have the condition corrected. Contact your
authorized Aud i dea ler.
If the ligh t illuminates, the electronic speed lim­
iter may also be ma lfunctioning . For more infor­
mation ¢

An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
signed a code . In case o f a malfunct ion, the com­
ponent will be identified and the fault stored as a
code in the control module memory .
The MIL light may also ill uminate if there is a
leak in the on-board f uel vapor recove ry system.
If the light illuminates after a refuelling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
