2013 AUDI A5 CABRIOLET brake fluid

scalding from hot coo lant by following
these steps.
- Turn
off the engi ne and a llow it to cool
down.
- Protect your face, hands and arms from
escapi ng fl uid and steam by cover ing
the cap with a large, thick rag .
- Turn the cap slowly and very ca refully
i n a cou nte r-clockw ise dir ect ion while
a pply ing lig ht, downwa rd p ress ure on
the top of the cap.
- T o avo id being burned, do no t sp ill an­
tifree ze o r coolan t on t he exh aust sys­
tem or ho t engine parts . Un der certain
conditions, the ethylene glyco l in en­
gine coolant can catch fire .
- Antifree ze is poisono us. Always store an­
tifreeze in its or iginal co ntainer and we ll
o ut o f the reac h of children.
- If you drain the coolant , it must be
caught and safely stored in a p roper con ­
tainer clear ly marked "poison".
(D Note
- Coolant po llutes the env ironment and
could ca use a n engine fire . Excess coo l­
ant wi ll be forced out through the pres ­
sure re lief va lve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added , the correct ratio between water
and antifreeze¢
page 219 must be re­
stored as soon as possib le .
@ For the sake of the environment
Drained coolant should not be re used . Al­
ways dispose of used c oolant while observ­
ing all envir onmental regulations .
Radiator fan
The radiator fan switches on automa tically by
itself
T he radiator fan is driven by the engine via the
V-be lt. The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant .
Checkin g and fillin g 221
An auxiliary electric radiato r fan* sw itches on
and
off depending on coolant temperature
and othe r vehicle ope rat ing con ditions.
After yo u switc h the engi ne off, the aux iliary
f an can con tinue r unning for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢ & , if
- t he temperatu re of the engine coo lant rises
due to the heat b uild -up from the en gine in
the engi ne compartment, or
- the engine compartment heats up be cause
the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal in jury nev­
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
contro lled and can switch on sud denly
even when the engine is not running.
- The a uxiliary radiator fa n switches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coo lant temper­
ature drops .
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
qui ck glance.
Fig. 17 9 En gin e compar tment: Cover o n the brak e flu­
i d reservoi r
Before you check anyth ing in the eng ine com­
partment ,
always re ad and heed all WARN­
INGS c::> ,& in Working in the engine compar t-
ment on page 212 . .,..

222 Check ing and filling
• Read the brake fluid leve l from the brake
fluid reservoir ¢
fig. 179, ¢ fig. 175. The
brake f lu id leve l must be between the "MIN"
and "MAX" markings.
The brake fluid reservoir is located at the rear partition of the engine compartment on the
left side ¢
page 214 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
I f the brake fluid level falls
considerably be­
l ow the "MIN" mark, the brake wa rning/indi ­
cator light (U .S . mode ls:
1111 , Canadian
models :. ) will come on
¢ page 15. Do not
continue to operate the vehicle. The complete brake system should be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause corrected . If the
brake fluid level is too low, the b rake war ning/
i ndicato r light w ill illuminate . Contact an au­
thor ized Audi dealer
imm ediately .
@ Tips
The brake f lu id reservoir is located unde r­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerably and
dec rease braking per formance.
Therefore, the brake flu id must be changed
e ver y two ye ars. A lways use new b rake fluid
which confo rms to Fede ral Motor Vehicle
S tanda rd "FMVSS 116 DO T 4".
The brake flu id reservoir can be difficult to
r each, therefo re , we recommend that yo u
have the brake fl uid changed by yo ur au tho r­
i z ed
Audi dealer . Your dealer has the co rrec t tools, the
right brake flu id and t he know -how
to do this for you.
A WARNING
'-
- Brake flu id is poisonous. It must be stor-
ed only in the closed or igina l container
out of the reach of children!
- Brake failure can res ult from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
spe cifi cat ion
J 17 03 and conforms to
Federa l Motor Vehi cle Standard 1 16.
Always chec k with yo ur authorized A udi
dealer to make sure yo u are using the
correct brake fluid. The cor rect type of
brake flu id is also ind icated on the
brake f lu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left i n the system too
long . This can se riously affect the effi­
c iency of the brakes as well as your
safety . T his could result in an accident.
W Note
Brake fluid will damage the pai nt of you r
vehicle .
@ For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
r equired and the necessary expertise, we
r ecommend that yo u have the brake flu id
changed by yo ur autho rized Aud i dea le r.
Battery
General information
U nder normal operat ing cond itions, the bat­
te ry in your Audi does not need any ma inte­
nance. With
high outside temperatu res or
long da ily drives we recommend that you have
the e lectrolyte leve l che cked by an autho riz ed
A udi dealer or qu alified workshop. The elec­
tro ly t e level should also be checked e ach time

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
vehicle, 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 i nclud­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separat ion and blowouts.
A voidin g 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 tires 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 wheels 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 it ion if
they are mounted on rims .
Tires an d wheel s 22 7
New tires
New ti res have to be broken in¢& .
The tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
patte rn.
H idden damage
Damage to tires and r ims 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
thorized Audi dea le r or q ua lified wor kshop .
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 254.
A WARNING
New tires or t ires that are o ld, 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 worn 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
speeds. 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.

All wheel dri ve
Vehicles w ith quattro ® must always have tires
of the same size, construction and tread type. F or detai ls see
¢ page 184 .
.8, WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a veh icle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do not grip well on wet roads and increase
your risk of "hydrop lan ing" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .
