2020 AUDI A5 brakes

Driver assistance

7} - Traffic jam assist switches off if the driver
does not take over steering after multiple driver
intervention requests. The system brakes the ve-
hicle until it is stationary.
Steering intervention request
If no steering activity is detected or the steering
power from the system is not sufficient, the driv-
er steering intervention request will alert the
driver using audio and visual signals. Take over
the steering and keep your hands on the steering
wheel so that you will be ready to steer at any
time.
If the driver does not take over steering, adaptive
cruise control (with traffic jam assist) will be
switched off. The system brakes the vehicle until
it is stationary.*

Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— The activated traffic jam assist is only an as-
sist system, and the driver is still responsi-
ble for controlling the vehicle. The driver is
especially responsible for braking, steering,
starting to drive, and controlling the speed
and the distance from other vehicles.
— Turn on the traffic jam assist only if the sur-
rounding conditions permit it. Always adapt
your driving style to the current visual,
weather, road, and traffic conditions.
— Switch the traffic jam assist off temporarily
when driving in turning lanes or highway ex-
its. This prevents the vehicle from accelerat-
ing to the stored speed when in these situa-
tions.

G) Tips
— Always keep your hands on the steering
wheel. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
— Pay attention to applicable local regulations
relating to driving tasks, leaving space for
emergency vehicles, etc. The driver is always
142
responsible for following the laws that are
applicable in the location where the vehicle
is being operated.
— If traffic jam assist was deactivated through
the MMI, you can continue operating the
Audi active lane assist using the > fig. 125
button > page 144. The traffic jam assist
functions are no longer available.
— You are not necessarily guided to the center
of your lane.

Audi pre sense basic
Applies to: vehicles with Audi pre sense basic
Audi pre sense basic is automatically active at
speeds of approximately 20 mph (30 km/h) and
higher. The system can trigger the Audi pre sense
preemptive safety measures during emergency
braking and dangerous braking maneuvers as
well as in unstable driving situations, such as
oversteering or understeering.

ZA WARNING
Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
Audi pre sense front
Applies to: vehicles with Audi pre sense front

The Audi pre sense front system uses the data
from the radar sensors and calculates the proba-
bility of a rear-end collision. Within the limits of
the system, an impending collision with the front
of the vehicle can be detected in both urban and
rural speed ranges.
Early warning/acute warning
The system can recognize various dangerous sit-
uations. The early warning occurs if:
—Avehicle driving ahead brakes suddenly
— Your own vehicle approaches a significantly
slower vehicle or stationary vehicle in the direc-
tion of travel
The message Audi pre sense © or Audi pre
sense [MM and a warning tone will warn you about
the danger.
If there is an impending collision with vehicles,
there may also be an acute warning in the form
of sharp braking. You will also be warned by an
indicator in the instrument cluster display. When
this warning occurs, it may only be possible to
avoid a collision by swerving or braking strongly.
Automatic deceleration
If you do not react to the acute warning, Audi pre
sense can brake the vehicle to a full stop within
the limits of the system if the vehicle is traveling
at low speeds. This reduces the vehicle speed in
the event of a collision.
Automatic braking force increase
If Audi pre sense determines that you are not
braking strongly enough when a collision is immi-
nent, it can increase the braking force based on
the situation.

ZX WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— Audi pre sense front cannot overcome natu-
ral physical laws. It is a system designed to
assist and it cannot prevent a collision in ev-
ery circumstance. The driver must always in-
tervene. The driver is always responsible for
braking at the correct time. Do not let the
increased safety provided tempt you into
taking risks. This could increase your risk of
a collision.
— Audi pre sense front does not react to cer-
tain objects, such as people/cyclists, ani-
mals, crossing or oncoming vehicles, bars,
railings, or railcars.
— Audi pre sense front may be limited or un-
available when driving in curves.
— 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.
@) Tips
System functions may not be available if the
ESC is limited or switched off, or if there is a
malfunction.

trians.
Audi pre sense city is active at speeds of approxi-
mately 6 mph (10 km/h) and higher.
It can warn about pedestrians at speeds up to ap-
proximately 50 mph (85 km/h) and vehicles at
speeds up to approximately 155 mph (250
km/h).
Automatic deceleration is possible at speeds up
to 50 mph (85 km/h).
Early warning/acute warning
The system can recognize various dangerous sit-
uations. The early warning occurs if:
—Avehicle driving ahead brakes suddenly
— Your own vehicle approaches a vehicle in front
of you that is traveling at a significantly slower
speed or that is stationary
— A pedestrian is standing in the lane or is mov-
ing into the lane
A warning tone and the message Audi pre
sense Bo or Audi pre sense ww (depending on ve-
hicle equipment) will warn you about the danger.
If there is an impending collision with vehicles,
there may also be an acute warning in the form
of sharp braking. You will also be warned by an
indicator in the instrument cluster display. When
this warning occurs, it may only be possible to
avoid a collision by swerving or braking strongly.
Automatic deceleration
If you do not react to the acute warning, Audi pre
sense can brake the vehicle to a full stop within
the limits of the system if the vehicle is traveling
at low speeds. This reduces the vehicle speed in
the event of a collision.
Automatic braking force increase
If Audi pre sense determines that you are not
braking strongly enough when a collision is immi-
nent, it can increase the braking force based on
the
situation.

— Audi pre sense city cannot overcome natural
physical laws. It is a system designed to as-
sist and it cannot prevent a collision in every
circumstance. The driver must always inter-
vene. The driver is always responsible for
braking at the correct time. Do not let the
increased safety provided tempt you into
taking risks. This could increase your risk of
a collision.
— Audi pre sense city does not react to certain
objects, such as animals, crossing or oncom-
ing vehicles, bars, railings, or railcars.
— Audi pre sense city may be limited or un-
available in curves or when it is dark.
— 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.
(i) Tips
System functions may not be available if the
ESC is limited or switched off, or if there is a
malfunction.
Audi pre sense rear
Applies to: vehicles with Audi pre sense rear

Within the limits of the system, Audi pre sense
rear uses data from radar sensors in the rear area
of the vehicle and calculates the probability of a
rear-end collision with the vehicle behind you.
Audi pre sense preemptive safety measures can
be initiated if the risk of a collision with the vehi-
cle behind you is detected.

ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— Audi pre sense rear does not react to pedes-
trians, animals, crossing objects, and ob-
jects not detected as vehicles.

Parking and maneuvering

Starting the parking process
As soon as the vehicle has reached the correct po-
sition, a P will appear in the center display above
the selected parking space (3). The roof in the
parking aid display @) may show the required
braking or driving direction.
> Keep the vehicle as parallel as possible to the
parked vehicles or to the side of the road.
> Make sure that the parking space is suitable for
your vehicle >@.
Start parking using the park assist > page 163.
Maneuvering area
The vehicle can go off course during the parking
process
> A\. If there are obstacles within the
maneuvering area that block or endanger the
parking process, for example on the opposite
side of the street, a message may appear. You
may need to drive farther forward and stay closer
to the row of parking spaces.

ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— The driver is always responsible when enter-
ing or exiting a parking space and during
similar maneuvers.
— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not
become distracted.

@) Note
— Parking spaces classified as suitable by the
system may have been detected incorrectly.
The driver must decide if the parking space
displayed is suitable for the vehicle.
— Certain conditions near the parking space
may cause the parking process to fail, such
as if the parking space is near trees or posts,
or if the ground is covered, for example,
with gravel, snow, or ice.
162
G) Tips
— If you did not drive past a suitable parking
space too quickly, the system can also be ac-
tivated afterward by pressing Pe.
— The Electronic Stabilization Control (ESC)
must not be switched off during the parking
process. If the ESC intervenes, the parking
process will be canceled.
— You can also drive into a perpendicular park-
ing space yourself and then activate the sys-
tem. If this is the case, the front of the vehi-
cle should already be in the space (4)
= page 161, fig. 139 so that the sensors
can measure the space.
— The system is not available when certain as-
sist systems are switched on.
— If there are suitable parking spaces on both
sides of the street, for example on a one-
way street, you can change the side where
the system is searching for parking spaces
by activating the turn signal for the other
side or by pressing on that side in the center
display.
— The park systems do not provide support for
assisted parking on tight curves.
Park assist
General information
Applies to: vehicles with park assist
The park assist helps you when parking and exit-
ing parking spaces after the parking space
search. The park assist takes over the steering of
the vehicle while the driver accelerates, brakes,
and
monitors the vehicle's surroundings. Park as-
sist can be interrupted at any time.

ZA\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— The driver is always responsible when enter-
ing or exiting a parking space and during
similar maneuvers.
— Do not use this function if the vehicle cannot
move freely, for example when on a vehicle
jack.

burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the engine
compartment with caution.
— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.


@ Note
Do not continue driving if the coolant expan-
sion tank is empty. Do not add any coolant,
because air could enter the cooling system
and damage the engine. See an authorized
Audi dealer or authorized Audi Service Facility

passenger at a designated seating
position and the total weight of
any luggage in the vehicle. If you
tow a trailer, the weight of the
trailer hitch and the tongue
weight of the loaded trailer must
be included as part of the vehicle
load.
The Gross Axle Weight Rating
(“GAWR”) is the maximum load
that can be applied at each of the
vehicle’s two axles.
The fact that there is an upper
limit to your vehicle’s Gross Vehi-
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas-
sengers in the vehicle or passen-
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli-
ance sticker on the front end of
the driver's door.

Z\ WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per-
sonal injury, and even death.
—Carrying more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and in-
crease the risk of the loss of
vehicle control.
—The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
—Tires on a vehicle that has
been overloaded can fail sud-
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
—Always make sure that the to-
tal load being transported -
including the weight of a trail-
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle’s
Gross Vehicle Weight Rating.
