Jeep 2007 Liberty - Manual (Page 240)

PARKING BRAKE
To set the parking brake, pull the lever up as firmly as
possible. When the parking brake is applied with the
ignition ON, the “Brake Warning Light” in the instru-
ment cluster will light. To release the parking brake, pull
up slightly, press the center button, then lower the lever
completely.
NOTE: The instrument cluster “Brake Warning Light”
indicates only that the parking brake is applied. You must
be sure the parking brake is fully applied before leaving
the vehicle.
Be sure the parking brake is firmly set when parked, and the
gear shift lever is in the P (Park) position (automatic
transmission) or R (Reverse) or 1st gear (manual transmis-
sion). When parking on a hill, you should apply the parking
brake before placing the gear shift lever in P (Park), other-
wise the load on the transmission locking mechanism may
make it difficult to move the selector out of P (Park).
