• If the brake warning/indicator light doe s not go out after a few
seconds and the parking brake released, or lights up while you are
driving , the fluid level in the brake fluid rese rvoir is too low. If you
believe that it is safe to do so, proceed immediately at low speed
to the neare st authorized Audi dealer or qualified repair facility
and have the brake system inspected .
• Always keep in mind that after several brake applications , you
will need greater pressure on th e brake pedal to stop your vehicle .
Do not rely on strained brakes to respond with maximum stopping
power in critical situation s. You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident . •

temperature outside due to the heat rad iat ing from the engine .
T he unit of measurement for the temperature can be set in either °F

& WARNING
• Never use the outside temperatu re display to determine if a
road surface i s ic y or not . Keep in mind that road surfaces, espe­
cially bridges and o verpasses , could be ice covered and slippery
even at an out side temperature above 41 °F (+5 °C ).
• Always remember , even if the "snowflake " symbol (ice

[I) Tips
• If the vehicle is s tat io nary, o r if you are d riving a t a very low speed,
the temperature shown in the disp lay might be slightly higher than
t he act ual o utside temperature. This is caused by the heat being radi­
ated from the engine. •
