Electronic Stability Control (ESC)

ESC helps stabilize the vehicle during cornering maneuvers.

ESC checks where you are steering and where the vehicle is actually going. ESC applies braking pressure to any one of the vehicle's brakes and intervenes in the electric vehicle control system to assist the driver with keeping the vehicle on the intended path. It is not a substitute for safe driving practices. Always adjust your speed and driving to the road conditions.

Never drive too fast for the road conditions when cornering. ESC does not prevent a collision.

Excessive speed in turns, abrupt maneuvers, and hydroplaning on wet surfaces may result in severe collisions.

ESC operation

Activating ESC

When the Start/Stop button is in the POWER ON position, ESC and the ESC OFF indicator lights illuminate for about three seconds. After both lights go off, ESC is activated.

When ESC is activated, the ESC a indicator light blinks:

  • When you apply your brakes under conditions that may lock the wheels, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal.

  • If Smart Cruise Control has been used when ESC activates, Smart Cruise Control automatically disengages. Refer to the Smart Cruise Control (SCC).

  • When ESC activates, the vehicle may not respond to the accelerator as it does under routine conditions.

When ESC is active:

  • Drive slowly and NEVER attempt to accelerate.

  • Never turn off ESC while the ESC indicator light is blinking. You may lose control of the vehicle and crash.

Driving with wheels and tires with different sizes may cause the ESC system to malfunction. Before replacing tires, make sure all four tires and wheels are the appropriate size for your vehicle. Never drive the vehicle with different sized wheels and tires installed.

ESC OFF operation

Activating ESC OFF

State 1 (Traction and Stability Control limited)

Press the ESC OFF button briefly. The ESC OFF b indicator light illuminates and the message, 'Traction and Stability Control limited' appears.

The traction control function of ESC (electric vehicle control management) is limited, but the brake control function of ESC (braking management) still operates.

When driving

The ESC OFF mode should only be used briefly to help free the vehicle if stuck in snow or mud, by temporarily stopping operation of ESC, to maintain wheel torque.

To turn off ESC while driving, press the ESC OFF button while driving on a flat road surface.

To prevent damage to the transmission:

  • Do not allow wheel(s) of one axle to spin excessively while the ESC, ABS, and Parking brake warning lights appear. The repairs would not be covered by the vehicle warranty. Reduce motor power and do not spin the wheel(s) excessively while these lights appear.

  • When operating the vehicle on a dynamometer, make sure ESC is turned off (ESC OFF light illuminated).

  • If the Start/Stop button is moved to the OFF position when ESC is off, ESC remains off. Upon restarting the vehicle, ESC automatically turns on again.

  • Turning ESC off does not affect ABS or standard brake system operation.
