2016 AUDI A5 COUPE warning light

Check ing and F illing
The brake fluid rese rvoir is located at the rear
partition of the engine compartment on the l eft
side
c!,> pag e 193 .
The fl uid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for alarm.
If th e b rake fl uid level fa lls considerably be low
the "M IN" mark, the b rake warning/ind icator
lig ht ( U.S. mode ls :
1111 , Canadian models:. )
will come on
c!,> page 15 . Do not contin ue to oper ­
ate the vehicle . T he comp lete brake system
should be thoroughly checked by an authori zed
Aud i dealer or qualified workshop and the cause
corrected . If the brake flu id level is too low, the
b rake warning/indicator light will i llum inate.
Contact a n author ized Audi dealer
immediately .
{D) Tips
The brake fluid reservoir is located under­
neath the cover .
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs mo isture from the air. If the
water content in the b rake fluid is too high, cor­
rosion in the brake system may resu lt afte r ape ­
riod of t ime. The boiling poi nt of the brake flu id
will also decrease cons iderably and decrease
b raking perfo rman ce.
Therefore, the brake fluid must be changed
every
two year s.
Always use new brake fluid wh ic h con­
forms to Fede ral Motor Veh icle Standard "FMVSS
1 16 DO T 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we recommend that yo u have the
brake fl uid changed by yo ur autho rized
Audi
dealer .
Your dealer has t he corre ct tools, t he
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed orig inal container out of
the reach of chi ldren!
200
- Bra ke fa ilure ca n result from old or inapp ro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid t hat meets SA E speci­
fi ca ti on
J 170 3 and con forms to Federa l
Motor Ve hicle Standard 116 . Always check
wi th yo ur autho rized Audi dea le r to make
s ur e yo u are using the correct brake fluid .
The correct type of brake flu id is also ind i­
cated on the b rake fluid reservo ir .
- The brake fluid m ust be new . Heavy use of
the brakes can cause a vapo r lock if the
brake fluid is left in the system too long .
This can se riously affect the efficiency of
the b rakes as well as your safety . This
could resu lt in an accident .
(D Note
Brake fluid will damage the paint of your veh i­
cle.
@ For the sake of the environment
Because of the problem o f proper d isposa l o f
brake fluid as well as the spec ial too ls re­
q ui red a nd the necessary expertise, we rec­
omme nd that you have the bra ke f luid
changed by yo ur autho rized Aud i dea le r.
Battery
, General information
U nder normal operating condit ions, the battery
i n your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the elect ro ­
lyte level c hecked by an au thorized Aud i dealer o r
qualified workshop. The electro lyte level shou ld
a lso be che cked each time the battery is c ha rged
c:!,> page 202.
Have the batte ry chec ked when you take yo ur ve­
hicle in for service. You are we ll adv ised to re­
pla ce a battery tha t is older than 5 yea rs.
With certain types of airbag deployment, t he
batte ry is d iscon nected from the ve hicle electri­
ca l system for safety reasons
c!,> .&. in Repair, care
and disposal of the airbags on page 1 42. .,.

0 I-­co .... .... Disconnecting the battery terminals
Some vehicle func tion s (p ower w indow reg ula­
tors, for example) are lost i f th e battery termi ­
na ls are d isconnected. These functions have to be
relearned afte r the battery termina ls are con­
nected aga in. To prevent th is, the batte ry shou ld
only be disconnected from the vehicle e lectr ica l
system w hen abso lute ly necessary for repairs.
Vehicles not driven for long periods
If yo u do not drive you r vehicle over a period of
seve ral days or weeks, e lectrical components a re
g radually c ut back or sw itched off. This reduces
e nergy consumption and ma inta ins starting ca ­
pability over a longer pe riod
c:> page 175 .
Some of the conven ience f unctions may not ope r­
ate, s uch as the inte rior lights or the power seat
ad justment. The convenience functions will be
ava ila ble aga in whe n you tu rn o n the ignition and
start the engine .
Winter operation
During the winter months, battery capacity tends
to dec rease as temperatu res dr op. This is be­
cause more power is also consumed wh ile start ­
in g, and the head lights , rear wi ndow defogge r,
etc., are used more of ten .
Avoid un necessa ry power consumption, part icu­
l arly in city traffic or when t rave ling on ly short
d ista nces . Let your authorized Audi dealer check
the capaci ty of the vehicle battery be fore w inte r
sets in
