-If the indicator ligh t and the message ap­
pear
w hen stationar y or aft er sw itchin g the
ign it io n on ,
check if you can release the
park ing brake . After re leas ing the parking
brake, carefu lly drive to your authori zed
Audi dealer immed iately to have the mal­
function corrected. If you cannot re lease the
parking brake, seek professional assistance .
- If the indicator light and the message ap­
pear
w hile dr ivin g, the emergency braking
function may not be ava ilable . It may not be
poss ible to set the parking brake o r release
it once it has b een set. Seek professional as­
s istance.
(USA models): If the warning light
1111 and
the warning light
EiJ appear together, imme­
d iate ly contact your authorized Aud i dealer or
qua lified workshop to have all b rake pads in­
spected
Q page 20 .
When the light comes on, an audible warning
signal is also give n.
A WARNING
- Always observe the wa rnings in
Q page 231, before opening the hood
and checking the brake fluid .
- Driv ing with low b rake fluid is a safety
haza rd. S top the car and get professional
assista nee .
- If the
1111 (USA models)/ . (Canada
mode ls) b rake system indicator light
turns on together with the ABS and ESC indicator lights, the ABS/ESC regu lating
function may have failed. F unctions that
stabilize the vehicle are no longer availa­
ble. Th is could cause the vehicle to
swerve and increase the risk of sliding .
Drive carefully to the nearest authorized
Audi dealer or other qualified workshop
and have the malfunction cor rected.
- If the brake warning/indicator light does
not go out afte r a few seconds and the
par king brake is released, or ligh ts up while you are driving, the fluid leve
l in
the brake fl uid reservo ir is too low. If you
believe that it is safe to do so, proceed
immed iate ly at low speed to the nearest
author ized Audi dealer or qualified repair
facility and have the brake system in­ spected.
- Always keep in mind that after severa l
brake applications, you will need greater
pressu re on the brake pedal to stop you r
veh icle. Do not rely on st rained bra kes to
respond with maximum stopping powe r
in critical situations . 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
electromechanical parking brake .
If the indicator light - (USA models) /.
(Canada models) turns on, th@ parking brake
was set. If the parking brake is set when the
ignition is off, the indicator light turns off af­
ter about 20 seconds.
The warning/indicator light will go out when
the parking brake is re leased.
- (USA model s) ,. (Canada model s)
Caut io n: Vehicle parked too steep
If the indicator light blinks and the message
appears, there is not enough braking power to
keep the vehicle from rolling. The brakes have
overheated. The vehicle could roll away even
on a small incl ine .
