2018 AUDI A3 SEDAN warning

Wheels
~ Adapt your driving style to the situation.
~ Stop as soon as possible and check the tire(s) .
~ If it is possible to continue driving, see an au-
thorized Audi dea ler or authorized Audi Service
Facility immediately and have your tire(s) re­
paired or replaced.
A WARNING
Read and follow the important information
and
notes ~ page 350.
Storing new tire pressures
App lies to: ve hicles w ith tire press ure m on itoring system
Correctly stored tire pressure specifications are
necessary for reliable tire pressure monitoring.
-
It is always necessary to store the tire pressures
when the tire pressures are modified, for exam­ ple due to a change in load. or when new sensors
are installed .
~ Before storing the tire pressures, make sure the
tire pressures of all four tires meet the speci­
fied values and are adapted to the load
~ page 341, fig . 2 78 . Only correct and store
the pressure in tires whose temperature is ap­
prox imat ely the same as the ambient tempera­
ture .
If the temperature of the tire is higher
than the ambient air temperature, the tire
pressure must be increased approximate ly
3 .0 PSI (0 .2 bar) above the va lue on the sticker .
~ Switch the ignition on.
~ Select in the Infotainment system: IMENUI but­
ton
> Vehicle > left control button > Service &
checks > Tire pressure monitoring > Store tire
pressure > Yes, store now .
After storing the
tire pressu res, the t ire pressu re monitoring sys­
tem measures the current pressures wh ile driv­
in g and stores them as the new specified pres­
sures.
~ If the changed tire pressures are not displayed
in the Infotainment system, drive the vehicle
for approximate ly 10 minutes so that the sen­
sor signal from the wheels is received again.
During this adaptation phase, --.-- is displayed
for the pressure and temperature and the tire
pressure mon itor ing system is only partially
ava ilable. It only provides a warning if one or
352 more
tire pressures is below the minimum per­
mitted specified pressure.
If the
[I] ind icator light turns on and the mes­
sage
Tire pressure : wheel change detected .
Please check all tires and store pressures in
MMI also appears, the system has detected that
the position of the sensors has changed because
of a tire rotation, or that new sensors were in­
stalled. Store the new tire pressures.
A WARNING
Read and follow the important information
and notes
~pag e 350.
Malfunctions
Applies to: vehicles with t ire pressure mo nitori ng syste m
If the tire pressure monitoring system is not
available, t he
mm in dicator light appears in the
instr umen t cluste r display along with the mes­
sage
Tire pressure : malfun ction! See owner's
manual.
-
If the ffim ind icator light appears after switch­
in g the ignitio n on or wh ile dr iving and the
[IJ in­
dicator light also blinks for approximately one
minute and then stays on, there is a system ma l­
function . The fo llowing are examples of situa­
tions that could cause a malfunction:
- If the message appears at the end of the adap ­
tation phase, the system may not detect one or
several of the whee l sensors necessary for pres­
sure monitoring. This may res ult from one or
more whee ls being installed without wheel sen­
sors or with incompatible wheel sensors.
- A wheel sensor or another component has
fa iled.
- Using snow chains can affect the function of
the system because of the shielding effect of
the chains.
- The tire pressure monitoring system is not
avai lab le due to a ma lfunction.
- Transmitters with the same frequency, such as
headphones or remote-controlled devices, may
cause a temporary system malfunct ion due to
the strong electromagnetic field.

p roducts wit h house hold trash.
Car washes
The longer that deposits s uch as insects, bird
droppings, tree sap or road salt remain on the ve ­
h icle, the more the surface can be damaged. High
temperatures such as those caused by sunlight increase the damaging effect .
Before washing, rinse
off heavy deposits with
p lenty of water.
S tu bborn deposits s uch as bird d roppings or tree
sap are best removed with plenty of water and a
microfiber cloth.
A lso, wash t he u nderside of yo ur vehicle once
road sa lt stops being used for the season .

vided with the pressure washer . This is especia lly
important in regard to the pressure and spraying
distance. Do not aim the spray direct ly at sea ls on
s ide windows, doors, the hood, the luggage com­
partment lid or the panorama g lass roof * or at
tires, rubbe r hoses, insula ting material, the pow­

- Never use the screw drive r hex head to
t ighten whee l bolts, since the bolts cannot
attain the necessary tightening torque if you
use the hex head, potentially causing an ac­
cident.
-The factory -supplied jack is intended only
for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; you r isk injuring
yourself.
-Never start the engine when the vehicle is
ra ised, which could cause a n accident.
-Support the veh icle secure ly with appropri­
ate stands if work is to be performed under­
neath the vehicle; otherwise, there is a po­
tent ial risk for injury .
-Never use the jack supplied with your Audi
on another vehicle, particularly on a heav ier

The tire repair is only meant for temporary use .
Change the spare tire as soon as
possible¢ &.
If the t ire is p ie rced by an object su ch as a nail,
do not remove the objec t from t he tire.
The tire repair set is able to be used at tempera­
tures as low as -4 °F ( -20 °C) .
The tire mobility kit may not be us ed :
-if the t ire has cuts or punctures that are larger
than 0.16 in (4 mm)

A WARNING
-Read and follow the manufacturer's safety
precautions o n the compressor and in th e
in structions on t he bottle of sealant .
- If a tire pressure of 29 ps i (200 kPA) cannot
r e ached after inflating for 6 minutes, then
the tire is too severely damaged . Do not
continue d riving.
- If the t ire cannot be repaired with the tire
sealant, see an authorized Audi dealer or au­
tho rized Aud i Serv ice Facility for ass istance.
(D Tips
Do not operate the compressor for more than
six m inutes continuously, or it can overheat.
Once the compressor has coo led, you can con­
tinue to use it.
Completing
Applies to: vehicles with tire mobility kit
.,. Affix the st icke r that says "max . S O mph (max .
80 km/h)" that is provided with the tire mobili ­
ty kit within the driver's field of vision .
.,. Stop the vehicle after driving for about 10 mi ­
nutes and check the tire pressure.
.,. If the t ire pressure is lower than 19 ps i (130
kPA), then the tire is too severely damaged. Do
not cont inue driving.
A WARNING
Pay attent ion to the following after repair ing
the ti re:
- Do not drive faster than SO mph (80 km/h) .
- Avoid hard acceleration, brak ing sharp ly,
and fast cornering.
- The veh icle may become more diff icult to
control.
- If the t ire is too severely damaged, see an
authorized Audi dealer or authorized Aud i
Service Facility for assistance .

A WARNING
You or you r passengers could be injure d while
ch anging a whee l if you do no t follow these
safety precaut ions :
- If you have a fla t tire, move a safe dis tance
off the road. Turn off the eng ine, turn the
emergency flashers on and use other warn ­
ing devices to alert other motorists.
- Make sure that passenge rs wait in a safe
p lace away from the vehicle and well away
from the road and traffic.
- To help preven t the vehicle from moving
suddenly and possib ly slipping off the jack,
always fully set the park ing brake and bloc k
the front and back of the wheel diagonally
opposite the wheel being changed. When
one front wheel is lifted off the ground,
p lacing the Au toma tic Transmission in P
(Park) will
not prevent the vehicle from
mov ing.
