Sheift lock what the meaning the sheift lock

The term "shift lock" is the system that is in place to prevent the vehicle from being shifted out of Park into Reverse or Drive WITHOUT having the driver's foot firmly on the brake pedal. The brake light switch on the brake pedal closes a circuit that energizes a solenoid under the shifter. When the brake is applied, and the solenoid is energized, the shift lever is no longer "locked", and can be moved to the desired position.
The idea here stems from a phenonomon several years ago that dealt with the issue of "Sudden Intended Acceleration". What was happening here was, for some unknown reason, engines started developing high RPMS for no reason, and several accisents were reported due to this issue. The vehicle would accelerate "unintendedly", when putting into drive or reverse, and could hit something.

The shift lock is used to take transmission out of gear without the use of the key. Just push button, put gear into any gear.
just in case the gears lock up you can press it to release. It is usually normal if your parked on a steep hill because when you shift from a steep hill then it will be hard to put it in gear so you press the shift lock button.


hope this is clear
good luck:-)
