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.

Always follow the instructions in the op-
OA erating manual.

Hot motor components!
Rotating parts!

The radiator fan can switch on at any
time!

High voltage! The voltage in the high-
voltage system is high enough to cause
fatal injuries. Touching a damaged high-
voltage component can result in a fatal
electric shock.



— The coolant expansion tank cap is equipped
with a seal that must never be removed un-
der any circumstances > page 236. If the
coolant expansion tank is not sealed, con-
tact an authorized Audi dealer or authorized
Audi Service Facility.
— The cap on the coolant expansion tank must
never be opened when the coolant is hot.
The cooling system is under pressure.
—To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to chemicals to as short
atime as possible.


Z\ WARNING
— Switch the ignition off.
— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Keep children away from the motor com-
partment.
— Never spill operating fluids in the motor
compartment.
— Avoid short circuits in the electrical system.
— Never open the hood when there is steam or
coolant escaping from the motor compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
— The cap on the coolant expansion tank may
only be opened by an authorized Audi dealer

ZA WARNING
The voltage in the high-voltage system is high
enough to cause fatal injuries. Touching a
damaged high-voltage component can result
in a fatal electric shock. The components in
the high-voltage system are marked with a
warning label which warns of the high-volt-
age.
— The voltage level in the high-voltage system
is still dangerous and potentially life-threat-
ening when the ignition is switched off.
— Never perform work on orange high-voltage
cables or on high-voltage components. Only
authorized repair facilities that are certified
may perform work on the high-voltage sys-
tem.
