152 UNDERSTANDING THE FEATURES OF YOUR VEHICLE HDC also has the capability to sense rough terrain, and will automatically adjust to a slightly slower set speed (about.3 mph (.5 km/h) than normal. HDC operation can be overridden with brake application to slow the vehicle down below the HDC control speed. Conversely, if more speed is desired during HDC control, the accelerator pedal will increase vehicle speed in the usual manner. When either the brake or the accelerator is released, HDC will control the vehicle back to the original set speed. HDC is intended for low speed off-road driving only. At vehicle speeds above 30 mph (48 km/h), HDC will no longer function. When the vehicle speed drops below 30 mph (48 km/h), HDC function will automatically resume and the vehicle speed will return to the chosen set speed. WARNING! HDC is only intended to assist the driver in controlling vehicle speed when descending hills. The driver must remain attentive to the driving conditions and is responsible for maintaining a safe vehicle speed. ESP/BAS Warning Lamp and ESP/TCS Indicator Light The malfunction indicator lamp for the ESP is combined with the BAS indicator. The yellow "ESP/BAS Warning Lamp" and the yellow "ESP/TCS Indicator Light" in the instrument cluster both come on when the ignition switch is turned to the "ON" position. They should both go out with the engine running.
