ESC OFF usage
When driving
• It's a good idea to keep the ESC
turned on for daily driving whenever
possible.
• To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
Never press the ESC OFF button while
ESC is operating (ESC indicator light
blinks).
If ESC is turned off while ESC is operat-
ing, the vehicle may slip out of control.
✽ NOTICE
• When operating the vehicle on a
dynamometer, ensure that the ESC is
turned off (ESC OFF light illuminat-
ed). If the ESC is left on, it may pre-
vent the vehicle speed from increas-
ing, and result in false diagnosis.
• Turning the ESC off does not affect
ABS or brake system operation.
