Line Lock

The line lock feature works in conjunction with the stability control system to "lock" the front brakes and allow the rear wheels to spin freely during throttle application to achieve maximum traction prior to use at a race track. The line lock feature is intended for use at race tracks only and should not be used on public roadways.

The driver initializes the line lock feature through the message center, see the Owner's Literature for specific information. Once initialized, the line lock feature is not  activated and the vehicle brakes function normally. Line lock remains initialized up to 40 km/h (25 mph), once vehicle speed exceeds 40 km/h (25 mph) the line lock feature is automatically cancelled. Following initialization the line lock feature can be engaged, once engaged the ABS module closes isolation valves in the HCU to maintain the brake pressure in the front brake calipers while allowing the rear wheels to spin freely and a count-down timer begins. If the line lock feature is not used within this time limit or a vehicle condition requires the line lock feature to deactivate, the line lock feature is deactivated. Pressing the brake pedal while the line lock feature is activated automatically deactivates the line lock feature and normal brake function resumes.
