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

@ For the sake of the environment
Avoid actions that are damaging to the envi-
ronment. Show respect for the natural envi-
ronment and remain on marked routes.
@ Tips
Clean your vehicle after driving offroad. Dirt
and stones falling off your vehicle can affect
other road users.
Driving through water
If you must drive through water, follow these in-
structions:
— Check the stability of the ground, the current,
and the water depth. If the ground is unstable,
there is a strong current, or there are waves,
the water must only reach up to the lower edge
of the body at the most.
— Drive carefully and no faster than at walking
speeds to prevent the front of the vehicle from
creating waves, because they could splash
above the lower edge of the body. Oncoming
vehicles could also create waves.
— Do not stop the vehicle while in the water.
— Drive in reverse.
— Do not switch off the drive system.

Z\ WARNING
After driving through water, press the brake
pedal carefully to dry the brakes so that the
full braking effect will be restored.
@) Note
Vehicle components such as the motor, drive
system, suspension, or electrical system can
be severely damaged by driving through wa-
tele
@) Tips
If possible, avoid driving through salt water
because it increases the risk of corrosion. Use
fresh water to clean any vehicle components
that come into contact with salt water.

Hill descent assist
Applies to: vehicles with hill hold assist
The “& button is located in the function bar on
the lower display. It lights up when the system is
turned on.
Hill descent assist can assist you when driving
down hills by maintaining a constant vehicle
speed by automatically braking all four wheels.
You can adjust the speed using the accelerator
and brake pedals. The regulation depends on the
hill and the vehicle speed.
> Switching on: press e
> Switching off: press “ again.
Active regulation
Regulation begins shortly after you start driving
and is possible at speeds up to approximately 19
mph (30 km/h) and on hills that have an approxi-
mately 6-60% grade. If these conditions are met,
regulation will be activated and the indicator
light will turn on.
Ready mode
If one of the requirements for active regulation is
not met, the system will be in ready mode. The
a indicator light will turn on. Once the require-
ments are met again, the system will be able to
provide active regulation again.

ZA\ WARNING
— Be ready to apply the brakes at all times
when using the hill hold assist.
— Always adjust the speed to the visibility,
weather, road, and traffic conditions. The
system cannot replace the driver's atten-
tion.
— The system cannot maintain a constant vehi-
cle speed in all situations, for example when
on smooth or slippery ground. This can in-
crease the risk of an accident.
G) Tips
If you select the Audi drive select* offroad
mode, hill descent assist will switch on.

Assist systems
General information
Sra eel delay
ZA\ WARNING
— As the driver, you are always completely re-
sponsible for all driving tasks. The assist
systems cannot replace the driver's atten-
tion. Give your full attention to driving the
vehicle, and be ready to intervene in the
traffic situation at all times.
— Activate the assist systems only if the sur-
rounding conditions permit it. Always adapt
your driving style to the current visual,
weather, road, and traffic conditions.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— For the assist systems to be able to react
correctly, the function of the sensors and
cameras must not be restricted. Note the in-
formation on sensors and cameras
= page 130.



@ Tips
— Pay attention to applicable local regulations
relating to driving tasks, leaving space for
emergency vehicles, vehicle distance, speed,
parking location, wheel placement, etc. The
driver is always responsible for following
the laws that are applicable in the location
where the vehicle is being operated.
— You can cancel a steering or braking inter-
vention by the system by braking or acceler-
ating noticeably, steering, or deactivating
the respective assist system.
— Always check the assist systems settings be-
fore driving. The settings could have been
changed, for example by other drivers or by
using another user.
System limitations
ZA\ WARNING
—The use of an assist system cannot over-
come the natural laws of physics. A collision
cannot be prevented in certain circumstan-
ces.
— Warnings, messages, or indicator lights may
not be displayed or initiated on time or cor-
rectly, for example, if vehicles are approach-
ing very fast.
— Corrective interventions by the assist sys-
tems, such as steering or braking interven-
tions, may not be sufficient or they may not
occur. Always be ready to intervene.
@) Tips
— Due to the system limitations when detect-
ing the surrounding area, the systems may
warn or intervene unexpectedly or too late
in certain situations. The assist systems may
also interpret a driving maneuver incorrectly
and then warn the driver unexpectedly.
— The systems may not function as expected
in unusual driving situations, such as driving
offroad, on unpaved roads, on loose ground,
on inclines, or on grooves in the road.
— The systems may not function correctly in
unclear traffic situations, such as turning
lanes, exit ramps, construction zones, rises
or dips that obstruct visibility, intersections,
toll stations, or city traffic.
— The detection of the surrounding area can
be limited, for example by vehicles driving
ahead or by rain, snow, heavy spray, or light
shining into the camera.
—In trailer mode, some assist systems may be
limited, may not react as usual, or may be
unavailable. Please refer to the instructions
for towing a trailer located in > page 126.
— The steering wheel touch recognition may
be limited when you wear gloves. Steering

switched on, detected objects are marked in yel-
low @), within the limits of the system.
Pedestrian and wild animal warning
This system limits are based on the vehicle speed
and steering angle. Pedestrian and wild animal
warning encourages you to pay more attention.
If there are pedestrians or wild animals in front
of your vehicle that could pose a danger, the sys-
tem will direct your attention to this.
— Pedestrians or wild animals are highlighted in
red in the instrument cluster (2) and the J or
BAN symbol turns on @.
— When the head-up display* is switched on, the
additional indicator [AM or EM appears.

it will only become active again later.
If the driver does not take over steering, the lane
departure warning will no longer be ready to pro-
vide warnings. If the vehicle is equipped with
emergency assist and it is ready to function, it
will be activated > page 164.
Behavior when a turn signal is active
Applies to: vehicles with side assist: The system
will not warn you if you activate a turn signal be-
fore crossing the lane marker line. In this case, it
assumes that you are changing lanes intentional-
ly.
Applies to: vehicles with side assist: If the turn
signal is activated, the lane departure warning is
ready, and a lane change has been classified as
critical by the lane departure warning due to
vehicles traveling beside you or due to approach-
ing vehicles, then a noticeable corrective steering
movement will occur shortly before exiting the
lane. This will attempt to keep your vehicle in the
lane.

ZA\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 129.
— The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible for keeping
the vehicle within the lane.
— Corrective steering may not occur at all in
certain situations, such as during heavy
braking. Always be ready to intervene.

@ Tips
— Always keep your hands on the steering
wheel so you can be ready to steer at any
time. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
