High Range (Four-Wheel Drive Models) or
Two-Wheel Drive Models
On
This is the normal operating mode for ESP in 4WD HIGH
range and in two-wheel drive vehicles. Whenever the
vehicle is started or the transfer case (if equipped) is
shifted from 4WD LOW range or NEUTRAL back to
4WD HIGH range, the ESP system will be in this "On"
mode. This mode should be used for most driving
situations. ESP should only be turned to "Partial Off" or
"Full Off" mode for specific reasons as noted below.
Partial Off
This mode is entered by momentarily pressing the "ESP
OFF" switch. When in "Partial Off" mode, the TCS
portion of ESP, except for the "limited slip" feature
described in the TCS section, 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 required to gain traction. To
turn ESP on again, momentarily press the "ESP OFF"
switch. This will restore the normal "ESP On" mode of
operation.
