0 Note
Brake fluid will damage the paint of your vehicle .
For the sake of the environment
Because of the problem of proper disposal of brake fluid as well as
the special too ls required and the necessa ry expertise, we recom
mend that you have the brake fluid changed by your authorized Audi
dea ler .•
Battery
General information
Under normal operating condi tions, the battery in your Audi does
not need any maintenance. With
high outside temperatures or long
daily drives we recommend that you have the e lectrolyte level
checked by an au thorized Audi dealer or qualified workshop . The
e lectrolyte level should also be ch ecked each time the battery is
charged ~
page 344.
Have the battery checked when you take your vehicle in for service .
Yo u are well advised to replace a battery that is o lder than 5 years .
With certain types of airbag dep loyment, the battery is discon
nected from the vehicle electrical system for safety reasons~
& in
"Repair, care and disposal of the airbags" on
page 255.
Disconnecti ng th e batt ery termin als
Some vehicle functions (power window regulators , for example) are
lost if the battery termina ls are disconnected. These functions have
to be relearned after the battery terminals are connected again . To
prevent this, the battery should only be disconnected from the
vehic le electrical sys tem when abso lutely necessary for repairs .
Vehicles not driven for long per iods
If you do not drive your vehicle ove r a period of several days or
weeks, electrical components are gradually cut back or switched off .
T his reduces energy consumption and maintains starting capab ility
over a longer period
~ page 295 .
Take i nto consideration that whe n you u nlock your vehicle, some
convenience functions, such as the master key remote function or
powe r seat adjustme nt, may not be ava ilable. The convenience
functions will be available again when you turn on the ignition and
start the engine .
Wint er op erati on
Duri ng the winter mont hs, batte ry capacity tends to decrease as
temperatures drop . This is because more power is also consumed
whi le star tin g, and the headlights, rear window defogger, etc ., are
used more often.
Avoid unnecessary power consumption, particular ly in city traffic or
when trave li n g o nly short dis tances . Let your authorized Audi dea ler
check the capacity of the vehicle battery before winter sets in
~ page 344. A we ll cha rged battery w ill not only preven t starting
problems when the weather is cold, but will also last longer . ..,_
