Quick Access Systems are also available via the right-hand steering wheel Quick Access System Settings button, as shown in Fig..

Basic Information Screens

There are currently three top-level menu options under Basic Information:

• Home

• Trip

• Leg

The Home screen displays a fuel consumption bar graph, the current outside temperature, the vehicle charging system voltage, compass direction of travel, and odometer. See Fig..

The Trip report screen displays calculations based on the engine run time such as trip mpg. See Fig..

The trip Leg report screen which displays calculations based on engine run time such as length of trip leg, average speed, and hours. See Fig..

Drive Time Systems Screens

There are currently four menu options under Drive Time Systems:

• Speed

• Driving Assistance

• Eco Driver Feedback (discontinued in January 2020)

• Video

The Speed screen shows the current vehicle speed as well as temperature, odometer and PasSmart information. See Fig..

The Driving Assistance screens, depending on systems installed, show Lane Departure Warnings (LDW), Adaptive Cruise Control (ACC) information, Traffic Sign Display, and/or Side Guard Assist (SGA) information. See Fig..

The Eco Driver Feedback screens display bar graphs measuring driving behaviors that improve fuel efficiency and reduce vehicle wear. For fuller explanation, see the ‘Digital Gauges and System Monitors: ICUC’ section.

Depending on systems installed, video is recorded when active safety systems are engaged or unsafe driving conditions are detected.

Vehicle Operations Screens

There are currently five top-level menu options under Vehicle Operations:

• Gauges

• Diesel Particulate Filter

• Tire Pressure Monitoring

• Locks

• Vehicle Settings

For information on gauge screens and Tire Pressure Monitoring (TPM) see ‘Digital Gauges and System Monitors: ICUC’ in this chapter. Information on diesel particulate filter monitoring is covered in Greenhouse Gas Emissions and Fuel Consumption Standards Emissions and Fuel Efficiency. Information on Transmission Prognostics is covered in Mode Switch Automated and Automatic Transmissions. For information on Locks see Interaxle Lock Switch Drive Axles.

The Vehicle Settings screen provides access to settings for vehicle systems such as cruise control, transmission, and engine idle adjust. See Fig.

ICUC Maintenance Screens

There are currently five top-level menu options under Maintenance:

• Alerts

• Diagnostics

• Engine Maintenance

• Eaton Prognostics or Allison Prognostics [depending on vehicle's transmission]

• Maintenance System

Alerts screens show all active notices, cautions, and warnings. See Fig..

Fault codes are color-coded to indicate the severity of the fault. Red indicates a condition that may pose a threat to control of the vehicle. Amber indicates a condition that may result in damage to vehicle components or derating of engine power. Blue, grey, and green are used to indicate component status.

The Diagnostics screens show active diagnostic trouble codes. See Fig..

The Engine Maintenance screen shows engine hours. See Fig..

The Maintenance System screens give information about when maintenance is required. See ‘Other ICUC Gauges and Measurements’ in this chapter for more details.

Transmission prognostics screens are available for Allison and Eaton transmissions. Allison's screen displays information on the status of the oil filter, oil level, and oil life; the Eaton Ultrashift clutch transmission prognostics screen tracks the grease interval. If transmission health falls below acceptable limits, a message will pop-up on the driver display. See Mode Switch Automated and Automatic Transmissions for more information.

ICUC User Settings Screens

The ICUC Setting Options List screens, as shown in Fig., allow the driver to choose the following Settings:

• Dash Brightness

• Lighting Timing

• Units

• Time

• Gauge Positioning

• Key Alert

• Language

• Safety Systems

The ICUC has a photoelectric eye that automatically adjusts the dash back-lighting. The menu option Dash Brightness allows the driver to adjust the overall brightness off-set; an optional dash switch may also be available to accomplish this.

Lighting Settings control if the courtesy and entrance lights come on and how long they stay on.

Unit Settings control the measurement values for speed, distance traveled, temperature, pressure, and following distance.

Time Settings control the time display format (12h/24h) and local time zone offsets.

Gauge Settings allow the driver to change the order in which gauges are displayed.

Key Alert Settings control if the key alerts is on or off.

Language Settings allow the driver to set the ICU language to be in either English (American), Spanish (Mexican), or French (Canadian).

Safety System Settings allow the driver to turn safety features such as Traffic Sign Display, Side Guard Assist, and Side Guard Trailer on or off; features listed under this menu depend on vehicle specifications.

Quick Access Screens are activated by a button on the right hand steering wheel pod. There are up to six top-level menu options:

• Hysteresis

• Cruise Control

• Transmission

• Engine Idle Adjust

• Power Take Off

• Optimized Idle

Hysteresis allows the driver to set the overspeed and underspeed in mph (km/h).

Power Take Off allows the driver to customize the amount of power being transferred to auxiliary devices. See Idle Shutdown Timer Optional Engine Systems for information about this feature.

For information about Cruise Control, Transmission, and Engine Idle Adjust, see ‘Other ICUC Gauges and Measurements’ in this chapter.
