Cadillac 2009 CTS Automobile User Manual


 
EPB Apply
The EPB can be applied any time the vehicle is stopped.
The EPB is applied by momentarily lifting up on the
EPB switch. Once fully applied, the BRAKE light will be
on, and the DIC message “Park Brake Set” will be
displayed. If the light does not come on, or is flashing,
you need to have the vehicle serviced. Do not drive
the vehicle if the BRAKE light is flashing. See your
dealer/retailer. See Brake System Warning Light
on page 3-38 for more information.
If the EPB is applied while the vehicle is in motion, a
chime will sound, and the DIC message “Release Park
Brake Switch” will be displayed. The vehicle will
decelerate as long as the switch is held in the up position.
Releasing the EPB switch during the deceleration will
release the parking brake. If the switch is held in the up
position until the vehicle comes to a stop, the EPB will
remain applied.
If the BRAKE light is on, either the EPB is applied,
or there is a failure in the hydraulic brake system.
If this light is flashing, the EPB is only partially applied
or released, or there is a problem with the EPB. The DIC
message “Service Park Brake” will be displayed. If this
light is flashing, release the EPB, and attempt to apply it
again. If this light continues to flash, do not drive the
vehicle. See your dealer/retailer.
If the
Y light is on, the EPB has detected an error
in another system and is operating with reduced
functionality. To apply the EPB when this light is on,
lift up on the EPB switch and hold it in the up position.
Full application of the parking brake by the EPB system
may take a longer period of time than normal when
this light is on. Continue to hold the switch until the
BRAKE light remains on. If the
Y light is on, see
your dealer/retailer.
If the EPB fails to apply, the rear wheels should be
blocked to prevent vehicle movement.
