A WARNING ,~
- Work on the battery requires expert knowl­
edge. Contact an authorized Aud i dealer or
authorized Audi Service Fac ility for informa­
t ion regarding the v ehicl e batte ry. There is a
risk for chemical burns or e xplosions.
- Never open the vehicle battery . Do no t try to
change the batte ry elect ro lyte level. Other­
wise ex plosive gas will e scape from the bat­
tery and increase the r is k of an explosion.
@ Tips
If your vehicle is not driven for severa l wee ks
in very cold tempe ratu res, remove the battery
and store it in a pla ce where i t will no t freeze.
This preven ts the bat tery from being d am­
aged and needing to be replaced .
Working on the battery

General information
~check your tires regularly for
damage (punctures, cuts, crac ks
and bulges). Remove foreign ob­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
~ Have faulty tires or rims re­
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running direction can be maintained if
they are reinstalled.
~Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(D Note
-Please note that summer and winter tires are designed for
the conditions that are typical i n those seasons. Audi recom­
mends using winter tires dur­
i ng the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
214
and braking ability. If summer
tires are used in very cold tem­ peratures, cracks can form on
the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the rims does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.
