2020 AUDI E-TRON brake pads

Driving

system is cleaned at regular intervals. This is
done by applying the brake pads to the brake ro-
tors for a short period of time when driving at
high speeds when the windshield wipers are
switched on.
If the brake system becomes damp, for example
after driving in heavy rain, the braking effect may
be delayed. Other factors that could temporarily
increase the response time of the brakes include:
— Wet conditions
— Low temperatures, ice, and snow
— Roads covered in salt
— Dirty brake pads
Corrosion
Corrosion may form on the brake rotors if there is
no heavy braking, if the vehicle is not driven for
long periods of time, or if the vehicle is not driv-
en
frequently or for long distances. In this case,
braking heavily several times while driving at
high speeds can clean the brake rotors > A\.
To do this, select the “N” gear so that recupera-
tion is not used for braking.
Brake pads
New brake pads do not achieve their full braking
effect during the first 500 miles (800 km). They
must be “broken in” first. However, you can com-
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in period.
Because recuperation is also used for braking, the
break-in period for new brake pads is 500 miles
(800 km).
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
Brake pad wear increases when driving frequently
in the city or short distances or when using a very
sporty driving style.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision, the vehicle is
braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal, or
— The braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system
—The ESC, the brake system, or the vehicle elec-
trical system is not functioning

Z\ WARNING
— Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en-
danger other road users and increase the
risk of an accident.
— Due to the risk of injury, only have an au-
thorized Audi dealer or authorized Audi
Service Facility work on the brake system.
Incorrect repairs could impair the function.
— Never let the vehicle roll while the drive sys-
tem is switched off because this increases
the risk of an accident.
— During automatic braking maneuvers, the
brake pedal may move downward automati-
cally. To reduce the risk of injury, do not
place your foot under the brake pedal.
() Note
— Never let the brakes “rub” by pressing the
pedal lightly when braking is not actually
necessary. This can cause the brakes to over-
heat and increases braking distance and
causes wear.

— Observe the important information for driv-
ing downhill > page 98. This especially ap-
plies
when towing a trailer.
@ Tips
— If you retrofit your vehicle with a front spoil-
er, wheel covers or similar items, make sure
that
the air flow to the brakes is not ob-
structed. Otherwise the brake system can
overheat.
— Also refer to the information about brake
fluid > page 243.

Driving

— Wear caused by load does not constitute a
vehicle fault as defined by the terms of the
warranty.
Messages
GG / | Brakes: malfunction! Safely stop ve-
hicle
There is a malfunction in the brake system. If
EES / Gana Bialso turn on, there is a malfunc-
tion in the ABS, ESC, and braking distribution.
Do not continue driving. See an authorized Audi
dealer or authorized Audi Service Facility for as-
sistance. Read and follow the other safety pre-
cautions > A\.
Ga / @ Brake pads: wear limit reached. You
can continue driving. Please contact Service
The brake pads are worn. Drive to an authorized
Audi dealer or authorized Audi Service Facility as
soon as possible to have the malfunction correct-
ed.
Brake booster: limited functionality. You can
continue driving. Please contact Service
There is a brake booster malfunction. The brake
booster is available, but its effectiveness is re-
duced. The braking performance may be different
compared to the usual performance. Drive to an
authorized Audi dealer or authorized Audi Service
Facility immediately to have the malfunction cor-
rected.
Other indicator lights
When you switch the ignition on, the indicator
light BREN / Wiurns on briefly to check the
function. If the indicator light does not turn on,
there is a system malfunction.
If Be / B® stays on, there is a malfunction in
the brake system.
- Ahigh load was placed on the brakes from
driving downhill for a long period of time. Follow
the instructions in the message to utilize the en-
gine braking effect and to relieve the brakes.

AN WARNING
If a malfunction occurs in the ABS, ESC, and
braking distribution, interventions that stabi-
lize the vehicle will no longer be available.
This could cause the vehicle to swerve, which
increases the risk that the vehicle will slide.
Do not continue driving. See an authorized
Audi dealer or authorized Audi Service Facility
for assistance.

Electromechanical

ing the vehicle. You can remove your foot from
the brake pedal.
>» Releasing: when the ignition is switched on,
press and hold the brake pedal and press the
button.
If the red indicator light flashes, the braking
force has not built up enough or it has decreased.
You can also secure the vehicle by selecting the
“P” gear or pressing the brake pedal. Make sure
the indicator light is off before you start driving.
Automatically releasing the parking brake
when starting to drive
Requirement: the driver's door must be closed
