Buick 2010 Lacrosse Automobile User Manual


 
Driving and Operating 8-33
The system has a Park Brake
Status light and a Park Brake
Warning light. See Electric Parking
Brake Light
on page 421
. There
are also three Driver Information
Center (DIC) messages. See Brake
System Messages
on page 434
for more information. In case of
insufficient electrical power, the EPB
cannot be applied or released.
Before leaving the vehicle, check
the park brake status lamp to insure
the park brake is applied.
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 park brake status light will be
on. While the brake is being applied,
the status lamp will flash until full
apply is reached. If the light does
not come on, or remains flashing,
you need to have the vehicle
serviced. Do not drive the vehicle if
the park brake status light is
flashing. See your dealer/retailer.
See Electric Parking Brake Light
on
page 421
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 park brake status light flashes
continuously, 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
flashes continuously, 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 park brake warning 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
park brake status light remains on.
If the park brake warning light is on,
see your dealer/retailer.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
