ignition AUDI TT COUPE 2016 Repair Manual

Downloaded from www.Manualslib.com manuals search engine ~ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as well as the special tools re­
quired
and the ne cessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer.
Battery
General information
The battery in your Audi does not need any main­
tenance under normal operating conditions. Audi
recommends having the electrolyte level check
by an
authorized Audi dealer or authorized Audi
Service Facility
when there are high outside tem­
peratures or when driving all day. The electrolyte
level should also be checked each time the bat­
tery is charged ~page 247.
Have the battery checked when you bring your ve­
hicle
in for an inspection . It is a good idea to re­
place
the battery if it is more than S years old.
Sometimes when the airbags deploy, the battery
will be disconnected from the vehicle electrical
system for safety reasons ~.&in Repair, care
and disposal
of the airbags on page 203.
Disconnecting the battery
The battery should not be disconnected. Several
vehicle functions (power windows, for
example)
will be lost when the battery is disconnected. The
functions must be reprogrammed after connect­
ing the battery. To avo id this, the battery should
only be disconnected from the vehicle electrica l
system when it is absolutely necessary.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for several days or
weeks, electrical consumers are gradually scaled
back
or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time~ page 92. Some convenience
functions, su ch
as interior lighting or power seat
adjustment, may not be available under certain
circumstances. These convenience functions will
be available again once you switch
the ignition on
and start the engine.
Checking and Filling
Winter operation
A lot of stress is placed on the battery during
cold weather, which results in reduced starting
ability. Have the battery checked and recharged if
necessary
before the cold weather begins.
A WARNING
- Work on the battery requires expert know l­
edge. Contact an authorized Audi dealer or
authorized Audi Service Facility for informa­
tion regarding the vehicle battery. There is a
risk for chemical
burns or explosions.
- Never
open the vehicle battery. Do not try to
change the battery electrolyte level. Other­
wise explosive
gas will escape from the bat­
tery and increase the risk of an exp losion. ___ ....J
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor . Before you check anything
in the luggage compartment, read and heed all

-
Do not smoke.
-Do not interchange the positive and nega-
tive
cables.
-When working on the battery, be sure not to
short-circuit the terminals with tools or oth­
er metal objects. This would cause the bat­
tery to heat up very quickly, which could
lead to damage or explosion and personal
injury.
-
When a battery is charged, it produces hy­
drogen gas which is explosive and could
cause personal injury .
- Always keep
the battery well out of the
