HDC Function

WARNING: This page is about a different car, the 2006 Nissan Xterra. However, it is still accessible from the selected car via links, so may be relevant.

The hill descent control system will help maintain vehicle speed when driving under 25-35 km/h (15-21 MPH) on steeper downhill grades. HDC will provide braking allowing the driver to concentrate on steering while reducing the burden of brake and accelerator operation.
To operate the system, set the 4WD switch to 4H or 4 LO and push the HDC switch. The HDC indicator in the combination meter will turn on. While HDC is operating, the stop/tail lamps will illuminate.
If the accelerator or brake pedal is depressed while the HDC system is on, the system will stop operating.
During HDC operation, a mechanical noise may be heard. This is normal.
