driving safety, which increase the risk of an
accident. Do not continue driving. See an au-
thorized Audi dealer or authorized Audi

the brake system during heavy braking. This
could impair braking performance and driv-

cident.

Audi Service Facility. If this brake fluid is not
available, another high-grade brake fluid of
equivalent quality may be used, and it must
meet the U.S. Federal Motor Vehicle Stand-
ard (FMVSS) 116 DOT 4, Class 6.
~ Reusing brake fluid or using brake fluid that
is not permitted for your vehicle will signifi-
cantly impair the braking performance and
can even lead to a failure of the brake sys-
tem. The manufacturer of the vehicle is not
liable for failures or damage resulting from
this. It will also not be covered by the war-
ranty.
