returns but TCS remains off. When the vehicle speed
drops below 35 mph (40 km/h), the ESP system shuts off.
ESP is off at low vehicle speeds in 4L range so that it will
not interfere with off-road driving, but the ESP function
returns to provide the stability feature at speeds above 40
mph (48 km/h). The ESP/TCS Indicator Light will al-

NOTE: The "ESP OFF" message will display and the

and then moved out of the PARK position. This will
occur even if the message was previously cleared.
