Operation of HDC
When all operational conditions are met, HDC is applied
and the green HDC indicator blinks. HDC automatically de-
creases the vehicle speed to 7 km/h in the 2 wheel (2H) or
4 wheel high speed mode (4H) position. HDC automatically
stops at speeds less than 7 km/h or when the slope de-
scends slowly. It is normal to have strong vibrations and
noise from the brake system when HDC is applied.
HDC Operational Conditions
1. The HDC switch should be on (The green indicator on
the instrument cluster comes on).
2. A certain steep grade.
3. Driving for about 7 ~ 50 km/h in the 2 wheel (2H) or 4
wheel high (4H) speed position. Or driving for about 3 ~ 25
km/h in the 4 wheel low position.
4. The automatic gear shift lever is in the “D” or “R” position.
In case of the manual transmission, the gear shift is in the
forwarding “1” or “Reverse” position.
5. The accelerator or brake pedal is not depressed.
6. ESP (Electronic Stability Program, including BAS) is not
activated.
Deactivation Conditions of HDC
1. The HDC switch is off (The green indicator on the instru-
ment cluster is off too).
2. Less than required steep grade.
3. Vehicle’s speed is out of the operational ranges.
4. The accelerator or brake pedal is depressed.
5. ESP (including BAS) is applied.
6. Because of extended operation of HDC, the system is
overheated (The red HDC indicator illuminates).
• HDC is designed for driving on off-road steep grades.
• Unnecessary usage of HDC can cause malfunctions in the brake
system or ESP. Do not use HDC when driving on normal roads.
• If driving on a level road with HDC on and ready for use, HDC
may be applied during sharp cornering or passing over a speed
bump. Therefore, do not activate HDC while driving on normal
roads.
• If the red HDC indicator illuminates, HDC is overheated or
malfunctioning. If the indicator is on even after the system has
cooled down enough, have the nearest authorized dealer or ser-
vice center check the system.
• It is normal to have strong vibrations and noise from the brake
system when HDC is applied.
• In case of a manual transmission vehicle, the gear shift is in the
forwarding “1” or “Reverse” position. If HDC is attempted in the
“2” position, the engine may turn off.
