fi\. WARNING
-Always observe the warnings in
¢ page 174, Engine compartment, be­
fore opening the engine hood and check­
ing the brake fluid.
- Driv ing with low brake fluid is a safety
ha zard! Stop the car and get professional
assistance.
- USA models: If both, the~ warning
light and the
l;S warning light come
on at the same t ime, the rear wheels
could lock up first under hard braking.
Lock-up of the rear wheel brakes can
cause loss of vehicle cont rol and an acci­
dent . Have yo ur vehicle repaired immed i- ately by your a
uthorized Audi dealer or a
qualif ied workshop. Drive s low ly and
avoid sudden, hard brake application .
-Canada models: If both, the brake warn­
ing light . and the ABS warn ing light
liJ come on at the same time, the rear
wheels could lock up f irst under hard
brak ing . Lock-up of the rear wheel brakes
can cause loss of veh icle control and an
accident. Have your vehicle repai red im­
mediately by your author ized Audi dealer
or a qualified wo rkshop . Drive slowly and
avoid sudden, hard brake application.
- If the b rake wa rning/ind icator light does
not go out after a few seconds and the
parking brake is re leased, or lights up
while you are dr iving, the flu id leve l in
the brake flu id reservo ir is too low. If you
believe that it is safe to do so, proceed
immed iate ly at low speed to the nearest
author ized Audi dealer or qualified work­
shop and have the brake system inspect­
ed.
- Always keep in mind that after several
brake applications, you will need greater
p ressu re on the b rake pedal to stop you r
veh icle. Do not rely on strained brakes to
respond with max imum stopping powe r
in critical situations . You must allow for
increased braking distances . The extra
distance used up by fading brakes could lead to an accident .
t!i1 !.!r Safety systems
The I (USA models)/ . (Canada models) in­
dicator light mon itors the safety systems e .g .
(airbags , pretens ioners) and illuminates fo r a
few seconds each time you switch the ign it ion
on.
If the
I (USA models) /. (Canada models)
indicator light does not go out, or if it illumi­
nates while you are driving, or if it starts to
blink , then there is a malfunction somewhe re
in the system. If the ligh t does not i llum inate
when you switch on the ignition, this also
means there is a malfunc tion .
