Power Door Locks If your vehicle has power door locks, the switches are located on the driver's and the front passenger's armrests. Programmable Automatic Door Locks If your vehicle has power door locks and the remote keyless entry system, it will be equipped with an auto lock/unlock feature which enables you to program your vehicle's power door locks from the driver's seating position. If your vehicle has an automatic transmission, it will be programmed to have all the doors lock automatically when the shift lever is moved out of PARK (P). All the doors will unlock when the shift lever is moved back into PARK (P). If your vehicle has a manual transmission, it will be programmed to have all the doors lock when the vehicle speed is greater than 15 mph (24 km/h). The doors will unlock when the key is removed from the ignition. To personalize the automatic door locks, see "Automatic Door Locks" under DIC Controls and Displays on page 3-36. Remove the ignition key and press L (lock) to lock all the doors at once. To unlock all the doors, press U (unlock). On crew cab models, use the manual door lock lever on each rear door to lock or unlock the doors from the rear seating area. 2-8
