When the traction control system has been turned
off, you may still hear system noises as a result
of the brake-traction control coming on.
It is recommended to leave the system on for

be necessary to turn off the system when driving
in extreme off-road conditions where high
wheel spin is required. See If Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 388.
