above 40 mph (64 km/h). The “ESC OFF Indicator Light”
will always be illuminated in 4L range when ESC is in ESC
Full Off or ESC Partial Off.
NOTE: The “ESC OFF” message will display and an
audible chime will sound when the gear selector is placed
in the PARK position from any other position, and then
moved out of the PARK position. This will occur even if the
message was previously cleared.
WARNING!
With the ESC in ESC Full Off mode, the engine
torque reduction and stability features offered by ESC
and ERM are disabled. In an emergency evasive ma-
neuver, the ESC and ERM systems will not engage to
assist in maintaining stability. The ESC Full Off
mode is intended for off-road use only.
2H Range (4WD Models) Or 2WD Models
ESC On
This is the normal operating mode for ESC in 2H range and
on 2WD vehicles.
ESC Partial Off
When in ESC Partial Off mode, the TCS portion of ESC
(except for the limited slip feature described in the TCS
section), has been disabled and the ESC Off Indicator
Light will be illuminated.
This mode is intended to be used if the vehicle is in deep
snow, sand, or gravel conditions and more wheel spin than
ESC would normally allow is required to gain traction. To
turn ESC on again, momentarily push the ESC OFF switch.
This will restore the normal ESC 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 ESC Partial Off
mode by pushing the ESC Full Off switch. Once the
situation requiring ESC to be switched to the ESC Partial
Off mode is overcome, turn ESC back on by momentarily
pushing the ESC Full Off switch. This may be done while
the vehicle is in motion.
The ESC will restore to normal ESC On mode after each
key on.
