Hyundai Azera: Electronic stability control (ESC)

The Electronic Stability Control (ESC) system is designed to stabilize the vehicle during cornering maneuvers. ESC checks where you are steering and where the vehicle is actually going.

ESC applies the brakes at individual wheels and intervenes with the engine management system to stabilize the vehicle.

Electronic stability control (ESC) will not prevent accidents. Excessive speed in turns, abrupt maneuvers and hydroplaning on wet surfaces can still result in serious accidents.

Only a safe and attentive driver can prevent accidents by avoiding maneuvers that cause the vehicle to lose traction. Even with ESC installed, always follow all the normal precautions for driving - including driving at safe speeds for the conditions.

The Electronic Stability Control (ESC) system is an electronic system designed to help the driver maintain vehicle control under adverse conditions. It is not a substitute for safe driving practices. Factors including speed, road conditions and driver steering input can all affect whether ESC will be effective in preventing a loss of control. It is still your responsibility to drive and corner at reasonable speeds and to leave a sufficient margin of safety.

When you apply your brakes under conditions which may lock the wheels, you may hear a “tik-tik’’ sound from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your ESC is active.

ESC operation

ESC ON condition

• When the ignition is turned ON, ESC and ESC OFF indicator lights illuminate for approximately 3 seconds, then ESC is turned on.
• Press the ESC OFF button after turning the ignition ON to turn ESC off. (ESC OFF indicator will illuminate). To turn the ESC on, press the ESC OFF button (ESC OFF indicator light will go off).
• When starting the engine, you may hear a slight ticking sound. This is the ESC performing an automatic system self-check and does not indicate a problem.

When operating

When the ESC is in operation, the ESC indicator light blinks.

• When the Electronic Stability Control is operating properly, you can feel a slight pulsation in the vehicle. This is only the effect of driving on a brake control and indicates nothing unusual.
• When moving out of mud or driving on a slippery road, depressing the accelerator pedal may not cause the rpm (revolutions per minute) to increase. This is to maintain the stability of the vehicle and is a normal condition.

ESC operation off

ESC OFF state

• To cancel ESC operation, press the ESC OFF button (ESC OFF indicator light illuminates).
• If the ignition switch is changed to the OFF position when ESC is off, ESC remains off. Upon restarting the engine, the ESC will automatically turn on again.

Indicator light

When ignition switch is turned ON, the indicator light illuminates, then goes off if the ESC system is operating normally.

The ESC indicator light blinks whenever ESC is operating or illuminates when ESC fails to operate. The ESC indicator stays on when the ESC may have a malfunction. Take your vehicle to an authorized HYUNDAI dealer and have the system checked.

ESC OFF indicator light comes on when the ESC is turned off with the button.

WARNING - Electronic stability control

Drive carefully even though your vehicle has Electronic Stability Control. It can only assist you in maintaining control under certain circumstances.

CAUTION

Driving with varying tire or wheel sizes may cause the ESC system to malfunction. When replacing tires, make sure they are the same size as your original tires. Never operate the vehicle with different diameter tires installed at the same time.

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.

WARNING - Operating ESC

Never press the ESC OFF button while ESC is operating (ESC indicator light blinks). If ESC is turned off while ESC is operating, 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 illuminated).
• Turning the ESC off does not affect ABS or brake system operation.
