Tire Pressure Monitoring System (TPMS): OPERATING YOUR VEHICLE 4L LOCK (4-wheel drive low range center differential lock) In this position, engine power is supplied to the front and rear axles and you get better traction and more low-speed torque than when driving in "4H". Use this position when you need better traction than "4H" provides and more low-speed torque than "4H LOCK" provides, such as when climbing or descending steep, slippery hills etc. NOTE: When the transfer switch (if equipped) is turned to the "4L LOCK" position, the ESP® systems (other than ABS) will be canceled to provide improved vehicle traction, and the "ESP OFF" indicator light will come on. When the transfer switch (if equipped) is turned to the "4L LOCK" position, braketraction control can be activated. Braketraction control brakes the spinning wheel to distribute drive power to the other wheels for increased climbing ability or for better performance on a rolling hill or a slippery surface.
