Cadillac 2000 Seville Owner's Manual page 87

Reach under the driver's side of the instrument panel
and pull down on the manual release lever, which is
located behind the parking brake pedal. Pull down on
the yellow tab as shown by the arrow in the illustration.
If the parking brake does not release, you should have
your vehicle towed to your dealer for service.
NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat. You may have to
replace them and you could also damage other
parts of your vehicle.
If you are towing a trailer and are parking on a hill, see
"Towing a Trailer" in the Index.
Shifting Into PARK (P)
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll. If
you have left the engine running, the vehicle can
move suddenly. You or others could be injured.
To be sure your vehicle won't move, even when
you're on fairly level ground, use the steps that
follow. If you're pulling a trailer, see "Towing a
Trailer" in the Index.
