2018 AUDI A3 SEDAN air condition

Driving
When not being used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. This will save you approximately 12% fuel
at speeds from 62
-75 mph (100 -120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment
off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
(D Note
-Do not leave engine idling unattended after
starting. If warning lights should come on
to indicate improper operation, they would
go unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other prop­ erty.
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let . Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
@ Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.

.. Tilt the lever -c> fig. 83 downward¢ ,&..
.. Bring the steering wheel into the desired posi­
tion.
.. Push the lever against the steering column un­
til it is secure.
A WARNING
Incorrect use of the steering wheel adjust­
ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when the veh icle is stationary so that you do not lose
control of the vehicle.
-
-Adjust the driver's seat or steer ing wheel so
that there is at least 10 inches
(25 cm) dis­
tance between your chest and the steering
wheelr::!>page250, fig. 217. If you do not
maintain this distance, the airbag system
will not be able to provide its full protec­ tion.
c:> page 250, fig. 217.
- If your physical characteristics prevent you
from sitting at least 10 inches
(25 cm) or
more away from the steering wheel, see if
an authorized Audi dealer or authorized
Audi Service Facility can provide adapters that will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision. Always make sure
that the steering wheel is level with your
chest.

injuries. When the vehicle enters drive ready
mode, the status message
e-no"' ~... ap­
pears briefly in the instrument cluster display
and the needle in the power meter points to
READY ¢ page 9 5.
-Make sure that the selector lever is in the P
position and the ignition is switched off
when leaving the vehicle.
@ Note
-The high-voltage system can be damaged if
the vehicle underbody comes into contact
with the ground . Immediately drive your ve­
hicle to an authorized repair facility and
have it inspected.
- The electric drive motor can become very
hot during operation . Do not stop the vehi­
cle if there is oil, fuel residue or other flam­
mable substances under or next to the vehi­
cle.
Special considerations for the high-voltage
battery
Applies to: vehicles with plug-in hybrid drive
Please first read and note the introductory infor­
mation and heed the warnings
¢page 92.
All batteries age with use and over time. There
are things you should know about the care of the
high voltage battery that will help it keep giving
you good service and reliability over time. Please
read and keep the following information in mind
while you enjoy the performance and economy of
your vehicle.
- Be sure to charge the high voltage battery be­
fore leaving the vehicle parked and unused for a longer period of time. Ideally the high-voltage
battery should have a charge level between
40 % and 60 % when parked for a long t ime .
- If the battery charge level is below 3 %, never
park the vehicle for more than 21 days without
charging the high-voltage battery. Should you
have to park the vehicle for a long time, make
sure that the charge level is sufficient to help
prevent the battery from aging prematurely.
- Frequent and consecutive charging of the high­
voltage battery when the charge level is above
e-tron
98 % can also decrease the capacity of the
high-voltage battery. Make sure the charge lev ­
el is be low 98 % when you start the charging
process.
- Should the vehicle be parked for longer than
2 days at temperatures below -13 °F ( -25 °C),
the high-voltage battery could free ze and not
be able to provide energy to the electric motor.
The battery will start working again, once it
warms up . The battery can be warmed up when
the outside temperature rises or when the vehi­
cle is garaged appropriately. The battery will al­
so warm up when being used (sw itching on the
air conditioner, the heater or by driving the ve­
hicle) . Should you have to park your vehicle at
very low temperatures for longer than 1 day,
make sure that the high-voltage battery does
not freeze by parking the vehicle in a garage
that is heated or protected from the outside
temperature.
- The high-voltage battery can be damaged and
the capacity can be decreased when the vehicle
is parked for longer than 24 hours when the
ambient temperature is higher than 118 °F
(48 °C). Always make sure that the h igh-volt­
age battery is not exposed to temperatures
above 118 °F (48 °C) for a long time.
- Never park the veh icle in areas that are lik ely to
be flooded, such as beaches or river banks, and
never drive the vehicle in WA TER, on flooded
roads or through water that is higher than the
bottom of the vehicle body. The high-voltage
battery, along with other vehicle components,
can be damaged severely if the high-voltage battery is exposed to open water especially for
a longer time. However, you can drive through
water on roads under certain conditions
~ page 72.
Failure to heed any of these requirements can
age the battery prematurely and lead to a perma­
nent decrease of the high-vo ltage battery's ca­
pacity.
(D Tips
Always make sure that the high-voltage bat­
tery is not exposed to extremely low and high
temperatures as well as to water espec ially
for a longer time. Failure to protect and care

pletely disconnected from the power supply
and from the vehicle. Use a dry towel to
clean .
e-t ron
-If a 110 volt household socket is used for
charging, only connect one vehicle at a time
to the same circuit. Use a different circuit if
an additional vehicle needs to be charged at
the same time. Note the maximum permit­
ted current draw for the circuit . Contact a
qualified electrical technician if there is any
doubt .
A WARNING
The components in the Audi e -tron charg ing
system can trigger sparks which can cause
flammable or explosive fumes to ignite.
- To reduce the r isk of exp losions, espec ially
in garages, make sure the contro l unit is at
least 19 inches (SO cm) above the floor
when charging.
- Do not use the Audi e-tron charging system in areas at risk for exp losions .
- The Audi e-tron charging system is only suit­ ed for use on Audi vehicles and vehicles
within the Volkswagen Group . Using the de­
vice on vehicles made by another manufac­
turer is not authori zed.
@ Note
Make sure that you always use the suitable
power plug provided with the Audi e-tron
charging system for the corresponding mar­
ket. Contact an authori zed Audi dealer or au­
thorized Audi Service Facility for more infor­ mation .
(D Tips
-Only use the factory-provided charging ca­
ble from Audi or the Volkswagen Group to
charge your vehicle .
- For an uninterrupted charging process, we
recommend only charging using sockets
that are connected to a separately protect­
ed circuit .
- Using either NEMA sockets with a current
rating of at least 30 A or industrial sockets
in accordance with IEC 60309 when charg­
ing is recommended.

Fig . 1 23 Front o f veh icle: sensor
The rada r sensor area r:!) fig. 123 must not be cov­
ered with stickers, deposits or any other obstruc­
tions as it may impair the function of the adap ­
tive cruise control or the pre sense front . For in­
formation on cleaning,
see ¢ page 354 . The
same applies for any modifications made in the
front area .
The funct ion of the adaptive cruise contro l sys­
tem or pre sense front is limited in some condi ­
tions:
-Vehicles can only be detected when they are
within the sensor range
¢page 123, fig. 122 .
-The system has a lim ited abi lity to detect
vehicles that are a short d istance ahead , off to
the side of your vehicle or moving into your lane .
-Objects that are difficu lt to detect such as mo­
torcycles, vehicles with h igh ground clearance
or an overhang ing load are detected late or not
detected at all.
-When dr iving through curves ¢ page 125.
-When the vehicle is stationary ¢ page 125.
A WARNING
Always pay attent io n to the traffic aro und you
when adaptive cruise control is switched on .
As the driver, you a re st ill respons ible for your
own speed and the distance to othe r vehicles.
Th e adapt ive cr uise control is u sed to assis t
you . The driver must a lways take act ion to
avoid a collision . The driver is always responsi ­
ble for brak ing at the correct time .

-For safety reasons, do not use adaptive
cru ise control when dr iving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing). Using the system under these cond i­
tions could result in a co llision .
-Switch adaptive cruise cont rol off tempora­
rily when dr iv ing in turning lanes, on ex­
pressway ex its or in construction zones. This
prevents the veh icle from accelerating to
the stored speed when in these situat io ns.
-The adap tive cruise contro l system will not
brake by itself if you put yo ur foot on the ac­
celerator pedal. Doing so c an override the
speed and distance regulation .
- Adapt ive cruise control does not respond to
peop le, animals, or crossing or oncoming
objects .
-The funct ion of the radar se nsors can be af­
fected by ref lective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice .
