2012 AUDI A5 COUPE ABS

~ Read the brake fluid level from the brake
fluid reservoir ¢
fig. 207. The brake fluid
level must be between 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 239 .
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 brake wa rning/indi ­
cator light (U .S . mode ls: . , Canadian
models: . will come on
¢page 18 and
¢
page 30. Do not continue to operate the ve­
h icle. The complete brake system shou ld be
thoroughly checked by an authorized Aud i
dealer or qualified workshop and the cause
corrected . If the brake fluid level is too low,
the brake warning/ind icator light will illum i­
nate. Contact an autho rized Aud i deale r
im­
mediately .
(D Tips
The brake f luid rese rvoir is located unde r­
neath the cove r.
Changing brake fluid
Hove the broke fluid changed by an experi­
enced technician .
Brake fluid absorbs moistu re from the a ir . If
the water content in the brake fluid is too
hi gh, cor rosion in the b rake system may result
after a per iod of t ime . The bo ili ng po int of the
b rake fluid w ill also decrease considerab ly and
decrease b raking performance.
Therefore, the brake flu id must be changed
e ver y two year s. Always use new b ra ke fluid
which confo rms to Federal Motor Vehicle
S tandard "FMVSS 1 16 DOT 4".
The brake flu id rese rvoi r can be difficult to
reac h, therefo re , we recommend that yo u
h ave the br ake fl uid changed by yo ur autho r­
ized
Audi dealer . Your deale r has the co rrect
Checkin g and fillin g 247
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:

Battery
General information
U nder normal oper ating cond itions, the bat­
tery in your Audi does not need any ma inte­
nance . With
high outside temperat ures or
lo ng da ily drives we recommend that you have
t h e e lectrolyte leve l che cked by an autho riz ed
A udi de aler or qu alified workshop. The elec­
tro lyte leve l should also be checked e ach time

248 Checking and filling
Have the battery checked when you take your
ve hicle in for service. Yo u are well advised to
replace a battery that is older than 5 years .
W ith certa in types o f airbag deployment, the
battery is d isconnected from the vehicle elec ­
trica l system for safety reasons ¢
& in Re­
pair, core and disposal of the airbags on
page 176.
Disconnecting the battery terminals
Some veh icle func tions (power w indow regu­
l a tors, for example) are los t if the bat tery ter ­
minals a re disconnected . These functions have
to be re learned after the battery terminals a re
connected agai n. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system whe n absolutely necessary
for repairs .
Vehicles not driven for long period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­ n ents are gradually cut back o r switched off.
This reduces energy consumption and main ­
tains starting capab il ity over a longer period
¢ pag e 211.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustm ent. The conven ience
f u nctions w ill be ava ilable again when you
turn on the igni tion and st art the eng ine.
Winter operation
During the winter months, battery capacity
tends to decrease as tempe rat ures d rop . This
i s becaus e more powe r is also consumed while
start ing , a nd the headligh ts, rea r window de­
f o gger, etc., are used more o ften .
Avoid unnec essary power consumption, par­
ticular ly in c ity traffic or w hen t rave ling o nly
short d istances. Let you r auth o riz ed Audi
d ea le r che ck t he cap acity of the ve hicl e bat­
tery be fore w inte r se ts in

Tire pressure indicator appears
Appl ies to vehicles: w ith t ire pressure monitoring sys te m
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig . 2 15 Display: underin flati on wa rning
Fig. 216 Disp lay: System malfunction
Using the ABS sensors, the tire pressure moni­
tor ing system compares the t ire tread circum ­
fe rence and vibration characteristics of the in­
d iv idual tires.
If t he pressure decreases in one
or mo re tires, th is is indica ted in the instru­
men t clus ter with a
[I] warning symbo l and a

fig. 215. The driver message in the
disp lay goes out after 5 seconds . The drive r
message can be d isplayed again by pressing
the
! SET ! button. If only one tire is affected,
the display will indicate its pos ition.
The tire press ure monitoring system must be
reset via radio o r MM! * each time the p res­
sures are adjusted (e.g . when sw itching be­
tween partial and full load pressure) or after
changing or replacing a t ire on your vehicle

& WARNING ~
- If the tire pressure ind icator appears in
the instrument cluster display, one or more of your tires is significant ly unde r­
inflated. Reduce your speed immediately
and avoid any hard steering or b raking
maneuvers. Stop as soon as possib le and
check the tires and their pressures . In­
flate the tire pressure to the prope r pres­
sure as indica ted o n the v ehicl e's tire
p ressu re labe l

sig nifican tly un der- infla te d tire causes
the t ire to ove rheat and can lead to ti re
fa ilu re . Unde r-inflation also is l ikely to
impair the vehicle's hand ling and stop­
ping ability .

272 T ire s and wheel s
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter condit ions or un­
paved roads), the pressure monitor ind i­
cator may be delayed .
- Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle regist rat ion becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or acc idents
cou ld also resu lt.
