2013 AUDI A4 brake light

228 Check ing and filling
scalding from hot coolant by following
these steps .
- Turn off the eng ine and allow it to cool
down.
- Protect your face, hands and arms from escaping flu id and steam by cover ing
the cap with a large, thick rag .
- Turn the cap slowly and very carefully
i n a counter-clockwise direction while
apply ing l ight, downwa rd press ure on
the top of the cap .
- To avo id being burned, do not spi ll an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glyco l in en­
gine coolant can catch f ire .
- Antifreeze is poisonous . Always store an­
tifreeze in its or iginal container and we ll
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clear ly marked "poison".
@ Note
- Coolant po llutes the env ironment and
could cause an engine fire . Excess coo l­
ant will be forced out through the pres­
sure re lief valve 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
c::> page 226 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be re used. Al­
ways dispose of used coolant while observ­
ing all environmental regulat ions .
Radiator fan
The radiator fan switches on automatically 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 accord ing to the temperature of the
coolant. An a
uxiliary electric radiator fan* switches on
and off depend ing on coolant temperature
and other vehicle operat ing condit ions .
After yo u sw itch the engine off, the aux iliary
f an can continue running for up to 10 minutes
- eve n wit h the ignit ion off. It can even switc h
on again later by itself
c::> &. , if
- t he tempe rature of the engine coo lant rises
due to the heat build -up from the engine in
the engine compartment, or
- the engine compa rtment heats up because
the vehicle is parked in i ntense sunlight.
_& WARNING
- To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperat ure
controlled and can sw itch on suddenly
even when the engine is not running.
- The a uxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reaches a certai n temperature and will
continue to run until the coolant temper­
ature drops .
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.
F ig . 1 88 Engin e compart men t: Cover on the b rak e flu­
i d reservo ir
Before you check a nyth ing in the engine com­
partment,
always read and hee d all WARN ­
INGS c::> .&. in Working in the engine compart-
ment on page 219 . .,..

~ Read the brake fluid level from the brake
fluid reservoir ~
fig. 188, ¢ page 221,
fig . 184.
T he brake fluid level must be be ­
tween the "MIN" and "MAX" markings.
The brake f luid reservoir is located at the rear
partition of the engine compartment on the
l eft side
¢ page 221 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
If the brake fluid level falls considerably be­
l ow the "M IN" mark, the bra ke wa rning/ind i­
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 shou ld be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause co rrected . If the
b rake fluid level is too low, the b rake wa rn ing/
i nd icator lig ht w ill illuminate . Co ntact an a u­
thor ized Audi dealer immediately.
@ Tips
The brake f luid rese rvoir is located unde r­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experi­
enc ed technician .
Brake fluid ab sorbs moisture from the a ir. If
the water content in the brake fluid is too
hi gh, corrosion in the b rake system may result
after a per iod of t ime . The bo iling po int of t he
b ra ke fluid w ill also decrease con siderab ly and
d ec rease brak ing per forman ce.
Therefore, the brake flu id must be changed
every two year s. Always use new b ra ke fluid
which confo rms to Fede ral Motor Vehicle
S tand ard "FMVSS 1 16 DOT 4".
The brake flu id rese rvoir can be difficult to
r eac h, therefo re , we recommend that yo u
have the brake fl uid changed by yo ur aut ho r­
iz ed Audi dealer. Your dealer has the correc t
Checking and fillin g 229
tools, the right brake fl uid and t he know -how
to do this for you .
A WARNING
- Brake fl uid is poisonous. It must be stor­
ed only in the closed or iginal 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 fluid th at mee ts SA E
spe cificat ion
J 17 03 and conforms to
Fe dera l Mo to r Ve hicl e Standard 1 16.
Always check with yo ur autho rized Au di
dealer to make sure yo u are using the
correct brake fluid. The c orrect type of
brake f luid is also ind icated on t he
brake f luid reservoir .
- The bra ke fl uid must be new. Heavy use
of the brakes ca n cause a vapor lock if
the b rake fluid is left i n the system too
long. This can se riously affect the effi­
c iency of the b rakes as well as your
safety , T his could result in an accide nt.
(!) Note
Brake fluid will damage the pai nt of your
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 an d th e nec essary exper tise, w e
r ecomme nd that yo u have th e brake flu id
c hanged by yo ur aut ho rize d Aud i dea le r.
