warning AUDI A3 2015 Owners Manual

218 Check ing and F illin g
• Add coolant mixed in the correct ratio
¢page 216 up to the upper marking.
• Make sure that the fluid level rema ins sta-
ble. Add more coolant if necessary.
• Clove the cap securely.
A coo lant loss suggests a leak. Immediately
drive your vehicle to an authorized repair fa­
cility and have the coolant system inspected.
If the coolant system is not leaking, a loss can
come from the coolant cooking through over­
heat ing and being pushed out of the coolant
system.
.8, WARNING
The cool ing system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps .
- Do not open the coo lant expansion tank
cap with the engine hot . There is a risk of
burns.
- T urn off the engine and allow it to cool
down .
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- T urn the cap slowly and ve ry carefu lly in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap.
- To avoid being b urned, do not spill anti­
freeze or coo lant on the exhaust system
or hot eng ine parts. Under certain condi­
t ions, the ethylene g lycol in engine cool­
ant can catch fire.
- The coo lant add itive and the coolant can
be dange rous to your hea lth. For th is
reason, keep the coolant in the or ig inal
conta iner away from children. There is a
risk of poisoning.
- Whe n work ing in the engine compart­
ment, remembe r that the radiator fan
can swit ch on even if the ignition is
switched off, wh ic h increases the risk of
persona l inju ry .
(D Note
Do not add coo lant if the expansion tank is
empty. Air cou ld enter the cooling system
and damage the engine. If this is the case,
do not continue dr iving. See your author­
i zed Audi dealer or qualified repair fac ility .
Radiator fan
The radiator fan switches on automatically by
itself
An a uxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operat ing condit ions.
After you switch the engine off, the auxi liary
fan can continue running for up to 10 m inutes
- even w ith the ignition off.
It can even switch
on again later by itself¢.&. , if
- the temperature of the engine coo lant rises
due to the heat build- up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
.8, WARNING ,-
- To reduce the risk of personal injury nev-
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
controlled and can sw itch on suddenly
even when the engine is not ru nning.
- The auxiliary radiator fan sw itches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.

Brake fluid

The brake f luid leve l mus t be be­
tween the "MIN" and "MAX " ma rkings.
The location of the brake flu id reservo ir can be
seen in the engi ne compa rtment illust ra ti on
¢ page 212 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the b rake pads . Thi s is not cause for alarm.
If the brake fluid level falls
considerably be ­
low the "MIN" mark, the b rake wa rning/ind i­
cato r light . (U .S . models)/ . (Canadian
models) will come on
r:=;, page 18 . Do not con­
tinue to operate the vehicle. The comp lete
brake system should be thoroughly checked
by an authorized A udi dealer or other quali­
f ied fac ility and the ca use corrected . If the
br ake fluid level is too low, the brake warning/
indica tor light w ill illuminate. Contact an au·
thor ized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid abso rbs moist ure from the air. If
the water content in the brake fluid is too
Che cking and Fillin g 219
high, co rrosion in the brake system may resu lt
after a period of time . The boiling point of the
brake f lu id will also decrease conside rably and
decrease braking performance.
T herefore, the brake fluid must be changed
eve ry two year s. Always use new brake f luid
which conforms to Federal Motor Veh icle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoi r can be difficu lt to
reach, therefore, we recomm end that you
have the brake fluid changed by your author­
i z ed
Audi dealer . Your dealer has the correct
tools, the right brake flu id and the know-how
to do this for you .
A WARNING
-
-Brake flu id is poisonous. It must be stor-
ed only in the closed or iginal containe r
out of the rea ch of children!
- Brake failure can resu lt from o ld or inap­
p rop riate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SAE
spec ificat ion
J 1703 and conforms to
Federa l Motor Ve hicle Standard 116.
Always check with your authorized Audi
dealer to make sure yo u are using the
cor rect bra ke fluid. The cor rect type of
brake f luid is also i nd icated on t he
brake f lui d rese rvoir.
- The bra ke flu id must be new. Heavy us e
of the brake s can cause a vapo r lock if
the b ra ke fluid is left i n the system too
l ong . This can se riously affect the effi ­
ciency of the brakes as we ll as your
safety . This co uld resu lt i n an accident .
(D Note
Brak e fluid will dam age the pa int of your
vehicle .
@ For the sake of the environment
Because of the p rob lem of proper disposal
o f bra ke fluid as well as the spec ial too ls
r equired and the necessary exper tise, we
recommend that yo u have the brake flu id
changed by yo ur authorized Audi dea ler.

220 Checking and Filling
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte­
nance. With
high outs ide temperatu res or
long daily drives we recommend that you have
the electro lyte level checked by a service fa­
cility. The e lectrolyte level shou ld also be
checked each time the battery is charged
c:>page222.
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than 5 years.
With certain types o f airbag deployment, the
battery is disconnected from the vehicle elec ­
trica l system for safety reasons
c;, .&. in Re­
pair , care and disposal of the airbags on
page 156.
Disconnecting the battery terminals
Some vehicle functions such as power win­
dows are unavai lable if the battery termina ls
are d isconnected. These functions have to be
relearned after the battery terminals are con­
nected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
To reprogram the functions, proceed as fol­ lows:
Function Reprogramming

Digital clock c:>page 10
ESC indicator light The indicator light
goes out after driving
a few meters
Vehicles not driven for long periods
If you do not drive your vehicle over a period
of severa l days or weeks, e lectrica l compo­
nents are gradually sca led back or switched
off. This reduces energy consumption and
maintains starting capability over a longer pe­
riod
c;, page 190. Some of the conven ience
functions may not operate, such as the interi­
or lights or power seat adjustment. The con ­
venience functions will be availab le aga in
when you switch on the ignition and start the
engine.
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop. This
is because more power is also consumed wh ile
sta rting, and the headlights, rear window de­
fogger, etc. , are used more often.
Avoid unnecessary power consumpt ion, par­
ticularly in city traffic or when traveling only
short distances. Let your authorized Aud i
dealer check the capacity of the vehicle bat­
tery before winter sets in ~ page 222. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer.
A WARNING -
-Work on the battery requ ires expert
know ledge. Contact your authorized Audi
dealer qualified repair facility for infor­
mat ion regarding the vehicle battery.
There is a risk for chemical burns or ex­
p losions.
- Never open the vehicle batte ry . Do not
try to change the battery electrolyte lev­
el. Otherwise explosive gas will escape
from the battery and increase the risk of
an explosion .
(i) Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it w ill not freeze. This will ..,.

prevent it from being damaged and having
to be replaced .
Working on the battery
Be especially careful when working on or near
the battery.
The battery is loca ted in the luggage compart­
men t under the floor. Before yo u check any­
thing in the l uggage compartment,

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
veh icle, particularly considering the compara­
tively small patch of rubber on each tire that
assures that a ll- important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safely han­
d le, avoiding damage from road hazards and
r eg ularly inspect ing t ires for damage includ­
ing cuts, slashes irregu la r wear and overall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
Avoiding damage If you have to d rive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires Mark t ires when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re­
i nstall them .
When removed, the whee ls or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos ition if
they are mounted on rims .

H idden damage
Damage to tires and rims is ofte n not readily
visible . If you notice unusual v ib rat ion or the
vehicle pulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
ti res m ust be chec ked immed iate ly by an au­

Unidirectional tires
A un idirectional tire can be identified by ar­
rows on the sidewa ll, that po int in the direc­
tion the t ire is designed to rotate. You mus t
f ol low the specified di rection o f rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information
¢page 253.
A WARNING
New tires or t ires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
also be b roken-in. To reduce the risk of
losing control , a collision and serious
pe rsonal injuries, drive w it h special care
for the first 350 miles (560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowout and sudden de­
fl ation, cras hes and se riou s personal in­
juries . Have wo rn or damaged t ires re­
placed immediate ly.
- Ti res age even if they are not being used
and can fai l sudden ly, especially at hig h
spee ds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.

The correct tire pressure for the spare wheel is
l ocated on a label on the driver's side B-pillar.
Because tec hnical changes may be made to
vehicle equ ipment dur ing the model yea r, a l­
ways compa re the tire size designation on the
tire pressure label on your vehicle wit h the
tires on your vehicle . Make s ure that the tire
size information on the veh icle label is the
same as the s ize of the tires on the vehicle.
This is especially important if the vehicle be ­
longs to someone else or you bought the veh i­
cle with different rims/tires or you boug ht the
ve hicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing su re that
l oad limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
veh icle. These load limits are technically refer­
red to as the vehicle's Gross Vehicle We ight
Rating ("GVWR") . The Gross Ax le Weight Rat ­
ing ("GAWR") is the maximum load that can
be app lied at each of the veh icle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker label located on the
driver's side B-p illa r. The t ire pressure label o n
your Aud i lists the maximum combined
weight of a ll of the occupants and luggage or
other cargo that the vehicle can carry. For the
l ocation of the tire pressure labe l~
fig. 156.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more weight than yo ur vehicle
was designed to carry will prevent the
vehicle from handling properly and in­ crease the risk of a loss of veh icle con­
trol.
- The brakes on a veh icle that has been
overloaded may not be able to stop the
vehicle within a safe distance .
- Tires on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
t rol and a crash.

A WARNING
- Inco rrect tire pressures and/or underin­
flation can lead to a ser ious or fatal acci­
dent.
- Inco rrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle.
- Inco rrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
flation, caus ing loss of veh icle contro l.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressvre label located on driver's side 8-pil ­
lar.
T he recommended tire pressures are on the
ti re pressure label and in the table
~ page 229, Cold tire inflation pressure . This
means that the pressure m ust be checked and
adjusted when the tire has not been dr iven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up
as a result of internal frict ion as it flexes in
use. The tire pressure is h igher when the tire
has warmed up t han when it is "cold."
It is the inflation pressure in a "cold" t ire that
counts. Therefore, you should never let a ir out
of a warm tire to match "Cold tire inflat ion
pressure" recommendat io ns ~
page 229 . Th e
ti res wo uld then be unde rinfl ated and co uld
fail suddenly.
T he tire pressure label on your Audi lists the

Most ti res lose a ir naturally over time. They
can also lose some a ir if you drive ove r a pot­
ho le or hit a curb while parking . It is usua lly
not possible to see whether the radial tires
used today are under inflated just by looking
at them.
Therefore, be sure to check tire pressures at
l east once a month and always before going
on a long tr ip. Make sure to take the number
of people and the amount of luggage into ac ­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
" long." See
c::> page 233 , Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres­
sures . Check all of the t ires and be sure not to
forget the spare t ire . If the pressure in any tire
is too high when the tire is "cold ," le t air out
of the tire slowly with the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is correct for the l oad (passengers and luggage) and kind of
driving you plan to do .
I f the pressure in any tire is too low, note the
diffe rence between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the cor rect pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as lis ted on the on
your veh icle and in this manual and the k ind

Remember that the vehicle manufacturer, not
the tire manufacturer, determ ines the correct
tire pressure for the t ires on your vehicle .
It is important to check the tire pressure when
the tires are cold .
- Read the req uired ti re pressure from the tire
pressure label. The tire pressure labe l is lo ­
cated on the driver's side B-pi llar . - Tu
rn the va lve stem cap counter -clockwise
to remove it from the tire va lve .
- Place the air pressure gauge on the va lve.
- The tire pressu res should only be checked
and adj usted when the tires are co ld. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reins tall the valve stem cap on the va lve.
When should I check the tire pr essure ?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
the refore be che cked at least once a mo nth
and always before sta rting a jo urney. Do not
f orget to c heck the ti re p ress ure for the spare
whee l

When should I adjust the tire pressures?
Adjust the t ire pr essure to the load you are
ca rrying. After cha ng ing a whee l
or replacing
whee ls you have to adjust the ti re p ress ures
on all whee ls. In addition, you m ust then
store the new tire pressures in the tire pres­
s u re monitoring system

A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RIJ appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping abi lity.
- Inco rrect tire pressures and/or underin ­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout a nd sudden de­
f lation, ca using loss of veh icle cont ro l.
- The driver is responsible for the co rrect
tire pressures for all tires on the veh icle.
The appli cable pressure values are locat ­
ed on a sticker on the dr iver's side B-pil-
lar .
