function returns to provide the stability feature at speeds
above 40 mph (48 km/h). The “ESP/TCS Indicator
Light” will always be illuminated in 4L range when ESP
is off.
NOTE: The “ESP OFF” message will display and the
audible chime will sound when the shift lever is placed in
the PARK position from any position other than PARK,
and then moved out of the PARK position. This will
occur even if the message was previously cleared.
WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP and ERM are unavailable. In
an emergency evasive maneuver, the ESP and ERM
systems will not engage to assist in maintaining
stability. The “Full Off” mode is intended for off-
road use only.
