Daewoo MATIZ - Warning Lamp Operation; Brake System Fault

HYDRAULIC BRAKES 4A–5
DAEWOO M-150 BL2
WARNING LAMP OPERATION
This brake system uses a BRAKE warning lamp located
in the instrument panel cluster. When the ignition switch
is in the III position, the BRAKE warning lamp should
glow and then go OFF when the ignition switch returns
to the II position.
The following conditions will activate the BRAKE lamp:
D Parking brake applied. The light should be on when-
ever the parking brake is applied and the ignition
switch is II.
D Low fluid level. A low fluid level in the master cylinder
will turn the BRAKE lamp ON.
