2021 AUDI E-TRON brake pads

Driving


ZA\ WARNING
Other road users may not be able to defini-
tively hear electric vehicles when they are
driving. This increases the risk of an accident
particularly when driving in areas with little
traffic, when maneuvering, or when driving in
reverse.

ient and environmentally-friendly

i}
Your driving style greatly influences the amount
of fuel and energy consumed, the environmental
impact, and the wear on the motor, brakes, and
tires. Note the following information for efficient
and environmentally-conscious driving:
— Select the Audi drive select* efficiency mode.
— Turn off electrical equipment that is not need-
ed, for example seat heating*.
— Anticipate upcoming traffic situations while
driving to avoid unnecessary acceleration and
braking.
— Avoid driving at high speeds.
— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— Brake early and evenly to use recuperation.

Brakes
ere el eiy
You can apply the vehicle's brakes using the brake
pedal.
Operating noise
Noises may occur when braking depending on the
speed, braking force, and outside conditions such
as temperature and humidity.
When the vehicle is stationary, the brake system
performs system tests at regular intervals. This
can cause brief noise and haptic feedback effects
on the brake pedal.
Braking effect
The response time from the brakes depends on
the weather and environmental conditions. To
ensure the optimal braking effect, the brake sys-
tem is cleaned at regular intervals. This is done
by applying the brake pads to the brake rotors 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 >

Driving

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 mi (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

ZA 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.
CG) 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 100. 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 236.

Driving

the brake booster is not working, you have to use
much more force when braking the vehicle.
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 BRING / @)
indicator light turns on briefly to check the func-
tion. If the indicator light does not turn on, there
is a system malfunction.
1f RG / @ 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.

Z\ 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.

> 1f i ii ® appears, the parking brake is hold-
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
and the driver’s safety belt must be fastened.
> Press the accelerator pedal to start to drive.

ZA WARNING
—To reduce the risk of an accident, always
make sure the vehicle is situated safely
while stationary.
— If the parking brake is set, it can release au-
tomatically when the accelerator pedal is
pressed. To reduce the risk of an accident,
do not inadvertently press the accelerator
pedal and always shift into “P” when the ve-
hicle is stopped.
— If the power supply fails, you cannot set the
parking brake once it is released, or release
it if it is set. Secure the vehicle against >
