ing brak e: sy ste m fault! Pl eas e contact dealer
- If the ind icator light and the message appea r
when stationary or after switching the igni ­
t ion on ,
check if you can release t he parking
brake. Afte r rele asing the par king br ake, ca re­
fully drive to your author ized Audi dealer im ­
mediately to have the malfunction corrected . If
you cannot re lease the parking brake, see k pro­
fessional assistance.
- I f the ind icator light and the message appear
while dri ving , the emergency braking functio n
may not be available. It may not be possible to
set the parking brake or re lease it once it has
been set. Seek profess ional assistance .
( U SA mode ls) : If the warning light
1111 and the
warning light
riJ appear togethe r, immediately
contact your author ized Audi dealer or qualif ied
workshop to have all b rake pads inspected
¢ page 19.
When the light comes on, an audible warning sig­
nal is also given.
A WARNING
- Always observe the warnings in
c::> page 216, before open ing the hood and
checking the brake fluid .
- Dr iving with low brake fluid is a safety haz­
ard . Stop the car and get profess ional assis -
tance .
1111>

-If the 1111 (USA models) . (Canada mod­
els) brake system indicator light turns on to­
gether with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
have failed. Functions that stabilize the ve­
hicle are no longer available . This could
cause the vehicle to swe rve and increase the
risk of sliding. Drive carefully to the nearest
authorized Audi dealer or other qualified
workshop and have the ma lfunction correct ­
ed.
- If the brake warn ing/ indicator light does
not go out after a few seconds and the park­
ing brake is re leased, or lights up while you
are driving, the flu id 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 w ith
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 brake.
If the indicator light- (USA models)/ .
(Canada models) turns on, the parking brake was
set .
- (USA m od els) • (Canada mod els) Ca u·
t io n: Vehi cle parked to o s teep
If the indicator light blinks and the message ap­
pears, the re is not enough brak ing power to keep
the vehicle from ro lling. The brakes have over­
heated. The vehicle could roll away even on a

_& WARNING
--Never rely exclusively on the outside tem­
perature display to determine if a road sur­
face is icy or not. Keep in mind that road
surfaces, especially bridges and overpasses,
could be ice covered and slippery even at an
outside temperat ure above 41 °F (+S °C).
- Always remember, even if the "snowflake"
symbol (ice warning) does not appear in the
d isp lay, black ice could be on the road.
- Always reduce your speed and drive with specia l care in co ld weather conditions when
the chance of encountering icy road surfaces
increases .
(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 slightly high­
er than the actual outside temperature . This
is caused by the heat being radiated from
the engine . .,..
