2015 AUDI A3 CABRIOLET sensor

168 Airbag system
-Objects between you and the airbag can
increase the risk of injury in an accident
by interfering with the way the airbag
unfolds or by being pushed into you as
the airbag inflates .
- Never place or attach accessories or
other objects (such as cup holders, tel­
ephone brackets, or even large, bulky
objects) on the doors, over or near the
area marked "AIRBAG" on the seat
backrests.
- Such objects and accessories can be­
come dangerous projectiles and cause
injury when the supplemental side air­
bag deploys .
- Never carry any objects or pets in the
deployment space between them and
the airbags or allow children or other
passengers to travel in this position.
-Always prevent the side airbags from be­ ing damaged by heavy objects knocking
against or hitting the sides of the seat­
backs.
- The airbag system can only be triggered
once. If the airbag has been triggered,
the system must be replaced by an au­
thorized Audi dealership.
- Damage (cracks, deep scratches etc.) to
the origina l seat covers or to the seam in
the area of the side airbag module must always be repaired immediately by an au­
thorized Audi dealer.
- If children are seated improperly, their
risk of injury increases in the case of an
accident
c> page 169, Child Safety.
- Never attempt to modify any compo­
nents of the airbag system in any way.
- In a side collision, side airbags will not
function properly if sensors cannot cor­
rectly measure increasing air pressure in­
side the doors when air escapes through
larger, unclosed openings in the door
panel.
- Never drive with interior door trim pan­
els removed .
- Never drive when parts have been re­
moved from the inside door panel and the openings they leave have not been
properly closed.
- Never drive when loudspeakers in the
doors have been removed unless the
speaker holes have been properly
closed.
- Always make certain that openings are
covered or filled if additional speakers
or other equipment is installed in the
i nside door panels.
- Always have work on the doors done by
an authorized Audi dealer or qualified
workshop.

Winter tires
By using all wheel drive, yo ur vehicle has good
forward motion with standard tires in winter
conditions. However, in winter we recommend
using winter or all season tir es on
all four
wheels, because this will imp rove the broking
effec t.
Snow chains
If there are snow chain laws, snow chains
must also be used on vehicles with a ll whee l
drive ¢
page 256, Snow chains .
Replacing tires
For vehicles w ith all wheel dr ive, only wheels
with the same rolling circumference should be
used . Avoid wheels with different tread
depths ¢
page 248.
Offroad vehicle?
Your Audi is not an offroad veh icle -there is
not enough ground clearance. For t his reason,
avoid difficult terrain. Refer to ¢
page 280.
.&_ WARNING -
-Also , in vehicles with all whee l drive,
adapt your driving style to the current
road and traff ic conditions. Do not let
the increased safety provided tempt you
into taking risks.
- The brak ing ability of your vehicle is lim­
ited to the traction of the wheels . In this
way, it is not different from a two wheel dr ive vehicle. Do not be tempted to ac­
celerate to a h igh speed when the road is
slippery th is increases the risk of an acci­
dent.
- Note that on wet streets, the front
wheels can "hydroplane" if driving at
speeds that are too high. Unlike front
wheel drive vehicles, the engine does not
rev higher suddenly when the vehicle be­
gins hydroplaning. For this reason, pay
attention to the road conditions regard­
less of your speed .
Smart Technolog y 193
Energy management
The starting ability is optimized
The energy management system manages
the electrical energy distribution and optimiz ­
es the availability of electrical energy for
starting the engine.
When a vehicle with a conventional energy
system is not driven for a long time , the bat­
tery is drained by equipment (for example the
immobilizer). In certain circumstances, there
could may no t be enough energy to start the
engine .
Your vehicle is equipped with an intelligent
energy management system for distr ibut ing
electric ity. This significantly improves the
starting ability and increases the battery life.
The energy management system Is made up
of
battery diagnosis , idling current manage­
ment
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the battery
charge level. The sensors determine the bat­
tery voltage, the battery current, and the bat­
tery temperature. The current charge leve l
and t he performance of the battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used while parked. With the engine
switched off, it manages the energy distribu­
tion to the different elect rical components.
Date from battery diagnosis is taken into ac ­
count for this.
Depend ing on the battery charge leve l, elec­
trical equip ment is switched off one item after
the other, to prevent the battery from drain­
ing and to retain the starting ability.
Dynamic energy management
While driv ing , dynamic energy management
distributes the appropriate amount of energy
to the e lectr ica l equipment . It controls the
battery charge level so that more energy is .,. •

Care and cleaning
General information
Regular, prope r care helps to maintain your
vehicle's val ue . It can also be a requirement
when submitting warranty claims for corro­ sion damage and paint defects on the body.
The necessary care products can be obtained
from your authorized Audi dea ler . Read and
follow the instructions for use on the packag ­
ing.
A WARNING
- Us ing clean ing and care products incor­
rect ly can be dangerous to your hea lth.

care p rod ucts with household trash.
Car washes
The longer that deposits such as insects, bird
droppings, tree sap or road salt rema in on the
ve hicle, the more the surface can be dam­
aged . High temperatures such as those
caused by sunlight inc rease the damag ing ef­
fect .
Before washing, rinse
off heavy depos its with
p lenty of water .
Stubborn deposits s uch as bird droppings or
tree sap are best removed with plenty of wa­
ter and a m icrofiber cloth.

tor, especially if the re a re accessories attach­
ed to yo ur vehicle.
If possible, use car washes that do not have
brushes .
Washing by hand
Clean the veh icle starting from the top and
working down using a soft sponge or cleaning
brush. Use solvent-free clean ing products .
Washing vehicle s with matte fini sh paint
by hand
To avoid damaging the paint when washing,
first remove dust and large particles from
your vehicle. Insects, grease spots and fi nger ­
pri nts are best removed with a special cleane r
fo r matte finish paint .
Apply the prod uct us ing a microfiber cloth. To
avo id damag ing the pa int surface, do not use
too much pressure .
Rinse the vehicle thoroughly with water. Then
clean using a neutral shampoo and a soft mi­
c rofiber cloth.

reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not operating properly . The
TPMS malfunction indicator is combined with
the low tire pressure tellta le . When the sys­
tem detects a malfunct ion, the telltale will
flash for approximately one minute and then
remain cont inuous ly illuminated. This se ­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is illuminat­
ed, the system may not be able to detect or
sig nal low t ire pressure as intended . TPMS
malfunct ions may occur for a variety of rea­
sons, including the installa tio n of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ion ing
properly. Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your veh icle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.

indicator appears
Applies to vehicles: with tire pressure monito ring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction .

is affected, the locat ion of that tire will be in­
dicated. The message turns off after a few mi­
nutes . You can d isplay the message aga in
c:::> page 2 8 .
The tire pressures must be stored in the menu
display again each time the pressures change
(sw itching between partial and full load pres ­
sure) or after chang ing or replacing a t ire on
