Not running the vehicle for long period s of
time
If you do not drive your vehicle for severa l days o r
weeks, electrical components are gradually re­ d u ced or switched off . This reduces energy con­
s u mp tion and mai ntain s the vehicle's ability to
st art over a long perio d of time
c::> page 1 21.
Some conven ien ce f unctions, such as inter ior
li ght ing o r power seats* may not wor k. T hese
convenience functions will be availab le aga in
once you sw itch the ignition on and start the en­
gine.
Winter operation
D ur ing the winte r mon ths, it is common for the
batte ry capac ity to decrease as the temperatures
become lower . This is because more power is
needed to start the vehicle and components such
as the headlights and the rear window defogger
a re used more freque ntly .
Avoid using power unnecessa rily, espec ia lly in
c ity dr iving o r on short t rips. Have your author­
i z ed Audi dealer or author iz ed Audi Se rvice Facili­
ty check the battery capacity be fore the start of
winter
c::> page 200 . A well -cha rged battery will
not only reduce sta rting prob lems in cold wea th­
e r, bu t it will a lso l ast longer.

e d ge. Con tact an a uthor ized Audi dealer or
