COMPASS/MINI-TRIP COMPUTER
The Compass/Mini-Trip Computer (CMTC) system is located on the right hand side of the instrument cluster. The CMTC is an electronic control module with a Vacuum Fluorescent Display (VFD) and two function switches. The CMTC is capable of displaying compass, temperature and trip computer information. Actuation of the STEP switch will cause the CMTC to change mode of operation while actuation of the US/M switch will toggle between English and Metric units. A reset of the trip computer is accomplished by pressing the STEP and US/M switches simultaneously.
The CMTC is active only when the ignition is on. Upon ignition the CMTC will turn on all of the segments in the display for 1 second then reverts to the last function screen that was displayed prior to the last ignition cycle. The functions that are available via actuation of the STEP switch are as follows:
- Compass and Ambient Temperature
- Average Trip Fuel Economy (AVE ECO)
- Estimated Range (RANGE)
- Present Fuel Economy (ECO)
- Trip Odometer (ODO)
- Elapsed Ignition On Time (ET)
- Blank Screen (off)
