110 UNDERSTANDING THE FEATURES OF YOUR VEHICLE WARNING! ESP (Electronic Stability Program) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. ESP cannot prevent accidents, including those resulting from excessive speed in turns, driving on very slippery surfaces, or hydroplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESPequipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user's safety or the safety of others. The ESP system has three available operating modes in 4H range. The system has one operating mode in 4L range. 2WD vehicles and 4WD vehicles in 2H range have two operating modes. 4H Range (4WD Models) or 2WD Models On This is the normal operating mode for ESP in 4H and 2WD vehicles. Whenever the vehicle is started or the transfer case (if equipped) is shifted from 4L range or NEUTRAL back to 4H range, the ESP system will be in this mode. This mode should be used for most all driving situations. ESP should only be turned to "Partial Off" or "Full Off" for specific reasons as noted below. Partial Off This mode is entered by momentarily depressing the ESP OFF switch. When in Partial Off mode, the TCS portion of ESP has been disabled and the ESP/TCS Indicator Light will be illuminated. All other stability features of ESP function normally. This mode is intended to be used if the vehicle is in deep snow, sand, or gravel conditions and more wheel spin than ESP would normally allow is
