Line Lock
Line lock is a feature intended for use at
tracks only and should not be used on
public roadways. Use of this feature may
result in significantly increased rear tire
wear. It is intended to condition the rear
tires to maximize traction prior to track use.
Line lock maintains brake force at the front
wheels, allowing the rear wheels to spin
with minimal vehicle movement.
This feature is located in the Track Apps
menu. Make selections through the 5-way
information display control and OK button
on the steering wheel.
Using Line Lock
There are three line lock stages:
• Initiated.
• Engaged.
• Off.
Initiating Line Lock
The initiation stage verifies that the vehicle
is ready for line lock function, and confirms
driver intent. Follow the prompts in the
information display to initiate line lock.
The following conditions must be met to
initialize line lock:
• The vehicle is on a level surface.
• The engine is running.
• The vehicle is traveling less than
25 mph (40 km/h).
• Selectable drive mode is not in slippery
mode.
• There are no electronic stability control
faults.
To cancel line lock once it is
initialized, press the Cobra
E308419
button.

Track Use
Once initiated, line lock is prepared for
activation and remains initiated up to
25 mph (40 km/h). If vehicle speed
exceeds 25 mph (40 km/h), line lock
automatically cancels.
Note: At a drag strip with a water box, it is
recommended that traction control is
disengaged prior to entering the water box.
This allows for a pull away out of the water
box after the tires are heated. Traction
control must be re-engaged to have launch
control capability at the start line.
Note: Leaving traction control off for launch
maintains set RPM but does not manage
tire spin.
Engaging Line Lock
Follow the prompts in the information
display to engage line lock after it is
initialized. To engage, firmly apply the
brakes. Then press the OK button. Once
engaged, release the brake pedal. The
front brakes remain applied and the rear
brakes release. At this point, the
engagement timer is initiated and shown
on the driver information display.
The following conditions must be met to
engage line lock:
• The vehicle is on a level surface.
• The engine is running.
• The vehicle is stopped.
• The parking brake is not applied.
• The driver door is closed.
• The transmission is in a forward gear.
• Selectable drive mode is not in slippery
mode.
• There are no electronic stability control
faults.
• The steering wheel must be in the
straight ahead position.
