The assist systems analyze the data from various
sensors installed in the vehicle. Depending on the
vehicle equipment, the area surrounding the en-
tire vehicle may be detected @ 9 fig. 96.

vehicle
— Ultrasonic sensors at the front, rear, and sides
of the vehicle!)
Some sensors are installed under vehicle compo-
nents and cannot be seen from the outside.

ZA\ WARNING
There are areas around the vehicle that the
sensors cannot detect. Objects, animals, and
people may only be detected with limitations
may not be detected at all. Always monitor
the traffic and the vehicle's surroundings di-
rectly and do not become distracted.

ZA WARNING
Applies to: vehicles with laser scanner
— The surface of the laser scanner can become
hot during operation, which increases the
risk of burns.
— The laser scanner contains a class 1 laser in
accordance with IEC 60825-1:2014. When
used according to regulations, the laser is
not dangerous. Opening the laser module
and removing covers is not permitted. Doing
so could cause permanent injuries to the
eyes.
— Any repair work on the laser module must
be performed by an authorized Audi dealer
or authorized Audi Service Facility; other-
wise the vehicle's operating license may be
voided. Incorrect repairs may cause limited

functionality and eye damage.

snow and ice, and are not covered by stick-
ers, deposits or any other obstructions, be-
cause this may impair the function of the
systems. Follow the information about
cleaning > page 263.
— The sensors can shift from an accident,

— Use the image on the display to assist you
only if it shows a good, clear picture. For ex-
ample, the image may be affected by the
sun shining into the lens, by dirt on the
lens, or if there is a malfunction.
— The camera view on the display portrays an
enlarged and distorted image. Under cer-
tain circumstances, objects may appear dif-
ferent and unclear on the display.

the vehicle will be operated. If the coolant addi-
tive percentage is too low, the coolant can freeze
and cause damage.



Coolant Freeze protec-
additive tion
Warm min. 40% min. -13 °F
regions max. 45% (25°)
Cold min. 50% max. -40 °F
regions max. 55% (-40 °C)

@) Note
— Before winter weather begins, have an au-
thorized Audi dealer or authorized Audi
Service Facility check if the coolant additive
in your vehicle matches the percentage ap-
propriate for the climate. This is especially
important when driving in colder climates.
— If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. Using other additives in-
creases the risk of damage. If this happens,
only use water and restore the correct mix-
ture ratio with the specified coolant additive
as soon as possible.
— Only refill with new coolant.
— Radiator sealant must not be mixed with
the coolant.
Coolant level

Follow the safety precautions > page 235, Gener-
al information.
Checking the coolant level
> Park the vehicle on a level surface.
> Switch the ignition off.

The coolant expansion tank is located in the ple-
num chamber under a cover. Slide the cover that
is located below the windshield wipers on the
front passenger's side toward the windshield and
remove the cover > page 237, fig. 158.
> Read the coolant level on the floating gauge for
the expansion tank. The coolant level must be
between the Min and Max markings when the
coolant is cold > fig. 159
Adding coolant
Requirement: there must be a residual amount of
coolant in the expansion tank >@).
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Allow the coolant to cool down.
> Place a large, thick towel on the coolant expan-
sion tank cap.
> Unscrew the cap carefully to the left > A\.
> Add coolant with the correct mixture ratio
=> page 237 until the floater gauge reaches the
Max marking.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Screw on the cap securely to the right.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected.

Z\ WARNING
— The engine/motor compartment in any vehi-
cle can be a dangerous area. Switch the igni-
tion off and allow the cooling system to cool
down. Always follow the information found
in > page 235, General information.
— Never open the hood if you can see or hear
steam or coolant escaping from the motor
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the motor
compartment with caution.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the |>

Checking and Filling

Fill the washer fluid for the windshield washer
system and the headlight washer system* when
the ignition is switched off.
@) Note
— The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions and the climate. A concentration
that is too high can lead to vehicle damage.
— Never add radiator anti-freeze or other addi-
tives to the washer fluid.
— Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint.
Service interval display
The service interval display detects when your ve-
hicle is due for service.
The service interval display works in two stages:
— Inspection reminder: after driving a certain
distance, a message appears in the instrument
cluster display each time the ignition is switch-
ed on or off. The remaining distance or time is
displayed briefly.
— Inspection due: if your vehicle has reached an
inspection interval, the message Inspection
due! appears briefly after the ignition is switch-
ed on and off.
Checking service intervals
You can check the remaining distance or time un-
til the next service.
Applies to: MMI: Select on the home screen: VE-
HICLE > Settings & Service > Service intervals.
Resetting the indicator
An authorized Audi dealer or authorized Audi
Service Facility will reset the service interval dis-
play after performing service.
@) Note
Adhering to the service intervals is critical to
maintaining the service life and value of your
vehicle. Even if the mileage on the vehicle is
low, do not exceed the time for the next serv-
ice.

Accessories and technical changes

(1) This device may not cause interference; and
(2) This device must accept any interference, in-
cluding interference that may cause undesired
operation of the device.
Long Range Radar* - Additional declarations
of compliance
This equipment has been tested and found to
comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These lim-
its are designed to provide reasonable protection
against harmful interference when the equip-
ment is operated in a commercial environment.
This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and
used in accordance with the instruction manual,
may cause harmful interference to radio commu-
nications. Operation of this equipment in a resi-
dential area is likely to cause harmful interfer-
ence in which case the user will be required to
correct the interference at his own expense.
Radiofrequency radiation exposure Information:
This equipment complies with FCC and IC radia-
tion exposure limits set forth for an uncontrolled
environment. This equipment should be installed
and operated with minimum distance of 20 cm
between the radiator and your body. This trans-
mitter must not be co-located or operating in
conjunction with any other antenna or transmit-
ter.
Audi e-tron charging system* - Additional
conformity declarations and statements
This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These lim-
its are designed to provide reasonable protection
against harmful interference in a residential in-
stallation. This equipment generates, uses and
can radiate radio frequency energy and, if not in-
stalled and used in accordance with the instruc-
tions, may cause harmful interference to radio
communications. However, there is no guarantee
that interference will not occur in a particular in-
stallation. If this equipment does cause harmful
interference to radio or television reception,
which can be determined by turning the equip-
ment off and on, the user is encouraged to try to
290
correct the interference by one or more of the
following measures:
— Reorient or relocate the receiving antenna.
— Increase the separation between the equip-
ment and receiver.
— Connect the equipment into an outlet on a cir-
cuit different from that to which the receiver is
connected.
— Consult the dealer or an experienced radio/TV
technician for help.
Integrated Toll Module* - FCC (USA) and
ISED (Canada)
