Driver Controls and Instruments safe manner as if the EVT–300 Collision Warning System were not present. A light sensor automatically adjusts alert and indicator light brightness depending on cab lighting conditions. A small speaker provides audible alert tones to warn of closing on an object ahead and, when equipped with an optional side sensor, of objects alongside when the turn signal is activated in preparation for a lane change. Ad- ditional tones indicate speaker volume, system failure, driver’s card status, and data extraction pass or fail.
The EVT–300 Collision Warning System is not a substitute for safe, normal driving procedures, nor will it compensate for any driver impairment, such as drugs, alcohol, or fatigue. The EVT–300 Collision Warning System may pro- vide little or no warning of hazards such as pedes- trians, animals, oncoming vehicles, or cross traffic. 1. The green power-on/driver’s card (optional) status indicator light illuminates when the system is acti- vated and the power-on LED test is complete. If the system is configured to require that the driver’s card be read, and it is not, the ON light blinks con- tinuously.
Failure to drive safely and use the system properly could result in personal injury and/or death and se- vere property damage. Driver Display Unit (DDU) NOTE: All system controls are located on the DDU. See Fig. 3.26 . Indicators to inform the driver about the system’s operation are located on both the DDU and the optional side sensor display. 2. Push in the volume control and power ON/OFF knob to turn power on or off. Turn the knob left or right to increase or decrease speaker volume. Press and hold the knob for 5 seconds and then release it to activate the failure display mode. NOTE:
The system may be configured to have no on/off capability and the volume may be config- ured to allow only some volume control. The DDU controls system power, range for vehicle warnings, speaker volume, and all other system func- tions. At the lower front edge of the DDU, a slot is pro- vided to insert the optional driver’s identification card. Alert and indicator lights advise of multiple warning lev- els, system power, system failure, and, if so configured, failure of the driver to insert the identification card. 3. The speaker is located under the top cover of the DDU. It sounds audible tones to alert the driver to potential hazards. Volume may be restricted to a range above a minimum level.
