Brake System Warning Light - Chevrolet 2009 Suburban Owner's Manual

Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power at
engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create full power. If there is
a problem with the battery charging system, this light will
come on or the SERVICE BATTERY CHARGING
SYSTEM DIC message will display. See DIC Warnings
and Messages on page 3-64 and Charging System Light
on page 3-39 for more information.

Brake System Warning Light

With the ignition on, the brake system warning light
comes on when the parking brake is set. If the vehicle
is driven with the parking brake engaged, a chime
sounds when the vehicle speed is greater than
5 mph (8 km/h).
3-40
The vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking, both
parts need to be working well.
If the warning light comes on and a chime sounds there
could be a brake problem. Have the brake system
inspected right away.
This light can also come on due to low brake fluid. See
Brakes on page 5-40 for more information.
United States
This light comes on briefly when the ignition key is
turned to ON/RUN. If it does not come on then, have it
fixed so it is ready to warn if there is a problem.
