5. ESP SYSTEM RELATED PRECAUTIONS

1. The HDC system is intended for use only on off-roads with a slope level exceeding 10%. Thus, do
not use it on public road.
2. Too frequent use of HDC system may weaken the durability of the ESP HECU and related systems.
Driver must turn the HDC switch to OFF position when driving on public and level roads.
3. As mentioned previously, when a driver make sharp turns or drive on rough roads, the HDC may
suddenly operate for these sudden shocks influencing the G sensor values. When such occurs, the
driver may panic because the vehicle speed drops sharply and the driver will experience difficulty in
controlling the vehicle.
During the HDC operation, a loud noise and the vehicle vibration may occur from the HECU and the
4. brake system, but this is a normal condition during the HDC operation.
The warning lamp flashes and warning beep sounds when the ESP is operating
5. When the ESP operates during vehicle movement, the ESP warning lamp on the instrument
panel flashes and beep comes on every 0.1 seconds. The ESP system is only a supplementary
device for comfortable driving. When the vehicle exceeds its physical limits, it cannot be controlled.
Do not rely on the system. Keep on the safe driving.
Feeling when ESP is working When the ESP system activates, the feeling can be different
depending on vehicle driving conditions.
6. For example, you will feel differently when the ESP system is activated during the ABS is operating
with the brakes applied and when the brakes are not applied on a curve.
If the ESP system operates when the brake is applied, the brake pressure will be increased on the
corresponding wheel which already has braking pressure for the ESP controls.
Noise and vibration that driver feels when ESP system is operating
The ESP system may transfer noise and vibration to the driver due to the pressure changes caused
7. by the motor and valve operations in a very short period of time. And, keep in mind that the output
and vehicle speed could be decreased without rpm increase due to the ASR function that controls
the engine power.
ARP Operation
During the ARP operation, vehicle safety (rollover prevention) takes the first priority and thus,
8. stronger engine control is in effect. Consequently, the vehicle speed decreases rapidly, so the driver
must take caution for the vehicle may drift away from the lane.
