2015 AUDI A3 set clock

The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer's glycol-based coolant addi-
tive Gl3 antifreeze with anticorros ion addi ­
tives (50% fo r USA models; 60% for Canadian
models) . This mixture both assures th e neces­
sary frost protect ion a nd p rotects me tal com ­
ponents in the engine 's coo ling system from
corrosion and scaling.
It al so raises the boil­
ing po int o f the coo lant .
D o no t reduce the concentration of t he coo l­
an t in the summer by ad ding plain w ate r.
The
proportion of coolant additive must be at
lea st 50 % but not more than 60%
to main­
tain ant ifreeze protection and cooling efficien­
cy. If the coolant frost protect ion is too low ,
the coolant cou ld free ze and damage the veh i­
cle heating and eng ine cooling system.
F or yea r-round driv ing, antifreeze is added at
the facto ry for temperatures down to:
- -3 1 °F ( -3 5°C) USA
- -4 0°F ( -4 0°C) Canada.
If you must add coolant, use a m ixture of wa ­
ter and coolant addit ive. M ixing the coolant
addi tive wi th dist illed wate r is recom mend ed.

tant if yo u live in a region whe re the win­
ter is extremely cold. If necessary, in ­
crease the proport ion of coolant additive
to 60%.

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
Power window one-c;, page 40, Correcting
touch up/down power window mal-
function functions
Remote control key If the vehicle does not
or react to the key, it
convenience key must be synchroni zed
c:>page 33
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 ..,.

252 What do I do n ow ?
-Support the vehicle securely with ap ­
propriate stands if work is to be per ­
formed underneath the vehicle;
otherw ise, there is a potential risk for
in Jury .

- Passengers mus t not rema in in the ve­
h icle when it is jacked up .
- Ma ke sure that passengers wait in a
safe p lace away from the vehicle and
well away from the road and traffic.
- Make sure jack posi tion is co rrect, ad­
just as necess ary and then contin ue to
raise the jack .
- Changes in temperature or load can af­
fect the height of the vehicle .
0 Note
Do not lift the vehicle by the s ill. Pos ition
the vehicle ja ck only at the designated lift­
ing poi nts on the sill. Othe rwise, your vehi­
