Jeep 2010 Grand Cherokee SRT - Owner Manual - Manual (Page 260)

The ESP system has two available operating modes.
On
This is the normal operating mode for ESP. Whenever the
vehicle is started, 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”
mode for specific reasons as noted below.
Partial Off
This mode is entered by momentarily pressing the
ЉESP
OFF” switch. When in “Partial Off Љ 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
ЉESP OFF”
switch. This will restore the normal “ESP On” mode of
operation.
NOTE: To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the “ESP Partial
ESP OFF Switch
