Park Interlock And Neutral Lock

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

Neutral lock is a requirement for the Transmission Control Switch (TCS). The TCS is always locked at ignition on when the engine is not running.

When driving in Sport (S), Drive (D) or Reverse (R) at a speed of more than 5 km/h (3 mph), the driver selects Park (P) or Neutral (N):

Without the brake pedal pressed, the TCS will be immediately locked once the vehicle speed falls to below 5 km/h (3 mph).
With the brake pedal pressed, the TCS will remain unlocked for as long as the brake pedal remains pressed, regardless of vehicle speed.

The transmission will only engage 'P' once the vehicle speed is less than 2 km/h (1 mph).

If the driver selects 'N' and releases the brake pedal with a vehicle speed of less than 5 km/h (3 mph), the TCS will be locked 2 seconds after 'N' is selected. The TCS will remain locked until the driver presses the brake pedal again.

If the transmission receives a range change request without the brake pedal pressed, the Transmission Control Module (TCM) initiates a soft lock function. The transmission will remain in 'P' or 'N', depending on the starting position.

If a transmission position letter is flashing in the message center and the vehicle has no drive, the driver must:

Press the brake pedal.
Reselect 'N' or 'P' on the TCS.
Select the required driving range, making sure that the brake pedal is pressed.

Rocking Function

The rocking function compliments the neutral lock function. For all changes from a non-driving range to a driving range, it is necessary to press the brake pedal (to release either the park interlock or neutral lock).

When selection from Reverse (R) to Drive (D) or from 'D' to 'R' is required without brake pedal input the rocking function gives a 2 second lock delay when Neutral (N) is selected. For example: car park maneuvering, 3 point turns or 'rocking' the vehicle from a slippery surface.

On China market vehicles, the rocking function is not applicable.
