Hyundai Azera: Vehicle stability management (VSM)

This system provides further enhancements to vehicle stability and steering responses when a vehicle is driven on a slippery road or a vehicle detects changes in coefficient of friction between right wheels and left wheels when braking.

VSM operation

When the VSM is operating:

• ESC (Electronic Stability Control) light will blink.
• The steering wheel may be controlled. When the vehicle stability management is operating properly, you can feel a slight pulsation in the vehicle. This is only the effect of brake control and indicates nothing unusual.

The VSM does not operate when:

• Driving on banked roads such as gradients or inclines
• Driving rearward
• ESC OFF indicator light (
  ) remains illuminated on the instrument cluster
• EPS (Electronic Power Steering) indicator light remains illuminated on the instrument cluster

VSM operation off

If you press the ESC OFF button to turn off the ESC, the VSM will also cancel and the ESC OFF indicator light (
) will illuminate.

To turn on the VSM, press the button again. The ESC OFF indicator light goes out.

Malfunction indicator

The VSM can be deactivated even if you do not cancel the VSM operation by pressing the ESC OFF button. It indicates that a malfunction has been detected somewhere in the EPS (Electronic Power Steering) system or VSM system. If the ESC indicator light () or EPS warning light remains
on, take your vehicle to an authorized HYUNDAI dealer and have the system checked.

• The VSM is designed to function above approximately 9 mph (15 km/h) on curves.
• The VSM is designed to function above approximately 18 mph (30 km/h) when a vehicle is driving or braking on a road with different grip under the individual wheels, such as having one or more tires on ice or mud and the others on dry asphalt.
• The VSM system is not a substitute for safe driving practices but a supplementary function only. It is the responsibility of the driver to always check the speed and the distance to the vehicle ahead. Always hold the steering wheel firmly while driving.
• Your vehicle is designed to activate according to the driver’s intention, even with the VSM installed. Always follow all the normal precautions for driving at safe speeds for the conditions – including driving in inclement weather and on a slippery road.

WARNING - Tire/wheel sizes

When replacing tires and wheels, make sure they are the same size as the original tires and wheels installed. Driving with varying tire or wheel sizes may diminish any supplemental safety benefits of the VSM system.
