Electronic Stability Control (ESC)

2C_ESCOffButtion

Electronic Stability Control (ESC) system helps stabilize the vehicle during cornering manoeuvres.

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 engine management 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 or too quickly when cornering. The ESC system does not prevent a collision.

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

ESC operation

ESC ON condition

When the Engine Start/Stop button is in the ON position, ESC and the ESC OFF indicator lights illuminate for about 3 seconds. After both lights go off, ESC is enabled.

When operating

When ESC is in operation, the ESC 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. This is normal and it means your ESC is active.

  • If Cruise Control has been used when ESC activates, Cruise Control automatically disengages. Refer to the “Cruise Control (CC)” section in Chapter 7.

  • When moving out of the mud or driving on a slippery road, the engine RPM (revolutions per minute) may not increase even if you press the accelerator pedal all the way. This is to maintain the stability and traction of the vehicle and does not indicate a problem.

ESC OFF condition

To cancel ESC operation:

  • State 1

    Press the ESC OFF button briefly. The ESC OFF indicator light and/or message “Traction control disabled” illuminates.

    The traction control function of ESC (engine management) is disabled, but the brake control function of ESC (braking management) still operates.

  • State 2

    Press and hold the ESC OFF button continuously for 3 seconds or more. The ESC OFF indicator light and/or message “Traction control and ESC disabled” illuminates and a warning chime sounds. In this state, both the traction control function of ESC (engine management) and the brake control function of ESC (braking management) are disabled.

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

ESC OFF indicator light (comes on)

WL_ESCWarningLamp

When the Engine Start/Stop button is pressed to the ON position, the ESC indicator light illuminates, then goes off if the ESC system is operating normally.

The ESC indicator light blinks whenever ESC is operating.

If the ESC indicator light stays on, your vehicle may have a malfunction with the ESC system. When this warning light illuminates, we recommend that your vehicle be inspected by an authorised HYUNDAI dealer as soon as possible.

The ESC OFF indicator light comes on when ESC is turned off.

When ESC is blinking, this indicates ESC is active:

  • Drive slowly and NEVER attempt to accelerate.

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

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

ESC OFF usage

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 whilst driving, press the ESC OFF button whilst driving on a flat road surface.

To prevent damage to the transmission:

  • Do not allow the wheels on one axle to spin excessively whilst the ESC, ABS, and Parking Brake warning lights illuminate. The repairs would not be covered by the vehicle warranty. Reduce engine power and do not spin the wheels excessively whilst these lights illuminate.

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

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