Jeep Grand Cherokee WK. Manual

The power lock system allows all of the doors and liftgate to be locked or unlocked electrically by operating a switch
on either front door trim panel. The power lock system receives non-switched battery current through a fuse in the
Junction Block (JB), so that the power locks remain operational, regardless of the ignition switch position.

The instrument cluster locks the doors automatically when the vehicle is driven beyond the speed of 25.7 Km/h (15
mph), all doors are closed, and the accelerator pedal is depressed. The rolling door lock feature can be disabled if
desired.

This vehicle also offers several customer programmable features, which allows the selection of several optional
electronic features to suit individual preferences.

The power lock system for this vehicle can also be operated remotely using the Remote Keyless Entry (RKE) trans-
mitters.

DOOR LOCK MOTORS

The lock mechanisms are actuated by a reversible electric motor mounted within each door. The power lock motors
are integral to the door latch units.

The power lock motors cannot be adjusted or repaired and, if faulty or damaged, the door latch unit must be
replaced.

CENTRAL LOCKING/UNLOCKING

The central locking system controls powered operation of the door and liftgate locks and the illuminated entry sys-
tem. Central locking included the following features:

•

Automatic locking of the doors and liftgate when the vehicle speed exceeds 13 km/h (8 mph).

•

Locking prevention with a door lock switch or the RKE transmitter if the key is in the ignition switch and the
driver’s door is open.

•

Driver selectable unlocking mode: unlock only the driver’s door or all doors and the liftgate with one press of
the RKE transmitter unlock button.

•

Automatic illumination of interior courtesy lamps when the vehicle is unlocked.
