& WARNING
• USA models : If the BRAKE warning light and the r,i:r warning
light come on together , the rear wheels could lock up first under
hard braking. Rear wheel lock -up can cause loss of veh icle control
and an ac cident. Have your vehicle repaired immediately by your
authorized Audi dealer o r a qualified workshop . Drive slowly and
avoid sudden, hard brake applications .
• Canada models : If the brake warning light ((D) and the ABS
warning light come on together, the rear wheels could lock up
first unde r hard braking . Rear wheel lock -up can cause lo ss of
vehicle control and an accident. Have your vehicle repaired imme­
diately by your authorized Audi dealer or a qualified workshop .
Drive slowly and avoid sudden , hard brake applications.
• If the brake warning /indi cator light does not go out after a few
second s and the parking brake released, or lights up while you are
driving , the flu id level in the brake flu id reser voir is too low . If you
believe that it is safe to do so , proceed immediately at low speed
to the nearest 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 the brake pedal to stop your vehi cle .
Do not rely on strained brakes to respond with ma ximum stopping
power in critical situations . You must allow for increased braking
distances . The extra di stance used up by fading brakes could lead
to an ac cident. •

The instrument cluster and center console illumination (gauges and

Be aware of the following difference between
models built to US or Canadian specifications:
• USA models: illumination of the instrument cluster (gauges and
needles), dash and center console around the gearshift lever is
controlled by a light sensor located in the instrument panel. The
instrument panel illumination will automatically become dimmer
as the daylight fades away and eventually will go out completely
when outside light is very low. This is to remind you, the driver, to
switch on the headlights before it gets too dark.
• Canada models: instrument panel illumination will stay bright
regardless of the intensity of ambient light . Always be aware of
changes in outside light conditions while you are driving. Respond
in time to fading daylight by turning the light switch to position
