5-44 Instruments and Controls STABILITRAK OFF If your vehicle has StabiliTrak, this message displays when you turn off StabiliTrak, or when the stability control has been automatically disabled. To limit wheel spin and realize the full benefits of the stability enhancement system, you should normally leave StabiliTrak on. However, you should turn StabiliTrak off if your vehicle gets stuck in sand, mud, ice, or snow and you want to rock your vehicle to attempt to free it, or if you are driving in extreme off-road conditions and require more wheel spin. See If the Vehicle Is Stuck on page 9‑22. To turn the StabiliTrak system on or off, see StabiliTrak® System on page 9‑54. There are several conditions that can cause this message to appear...
