The ESP system has multiple operating modes depend-
ing on vehicle type: Two-Wheel Drive (2WD) or Four-
Wheel Drive (4WD). Four-wheel drive vehicles may be
equipped with either a four-mode position (2WD/4WD
LOCK/4WD LOW/NEUTRAL) or a five-mode position
(2WD/4WD

AUTO/4WD

LOCK/4WD

LOW/

NEUTRAL) transfer case. If you have a four-wheel drive
vehicle, and want to determine which transfer case is on
your vehicle and how to operate it, refer to the “Four
Wheel Drive Operation” in this section.

All Two-Wheel Drive Vehicles and Four-Wheel
Drive Vehicles in 2WD, 4WD AUTO, or 4WD
LOCK Modes Can Choose the Following ESP
Operating Modes:

ESP On
This is the normal operating mode for ESP in 2WD/4WD
AUTO/4WD LOCK modes and in 2WD vehicles. When-
ever the vehicle is started or the transfer case (if

equipped) is shifted from 4WD LOW or Neutral, back to
4WD LOCK or 4WD AUTO, the ESP system will be in
this mode. This mode should be used for almost all
driving situations. ESP should only be turned to “Partial
Off” or “ESP Off” for specific reasons as noted below.

ESP Partial Off
This mode is entered by momentarily depressing the ESP
OFF switch. When in

ЉPartial OffЉ mode, the TCS portion

of ESP, except for the “limited slip” feature described in
the TCS section, has been disabled and the

ЉESP/TCS

Indicator Light

Љ 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 nor-
mally allow is required to gain traction. To turn ESP on
again, momentarily depress the ESP OFF switch. This
will restore the normal “ESP On” mode of operation.
