Chime System
The chime system is built into the CTM. The system also supports an external chime request from the instrument cluster. This feature allows the
instrument cluster to request a chime from the CTM for gauge problems and tell tale warnings. The CTM chime functions will have priority over the
MIC chime requests. There are two chime rates, Low; 50 chimes per minute for reminders and High; 80 chimes per minute for serious conditions that
require immediate attention. The high rate chime sounds when the key is left in the ignition and the driver doors is open or the headlights are left ON.
The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and
headlamp warning as long as the door is open. The seat belt warning chime is activated for 4 to 6 seconds, and all other chime conditions will activate
the chime once at the same time the warning light on the cluster is illuminated.
The chime will sound for the following conditions:
High Rate
-
Key in Ignition Warning ignition OFF, key in ignition, drivers door open
-
Ignition OFF, headlamps ON, drivers door open Low Rate
-
Seat belt warning-6 seconds after key ON (6 to 8 chimes) or until belt is buckled
-
Airbag lamp illuminated (3 times after prove-out)
-
Anti-lock lamp illuminated (2 chimes after prove- out if equipped)
-
Check engine lamp illuminated (2 chimes after prove-out)
-
Check gauges lamp illuminated (2 chimes)
-
Engine Temp High--when gauge enters red zone (2 chimes)
-
Low fuel- when fuel level reaches /8 tank (2 chimes)
-
Low washer fluid (2 chimes)
-
Wait to start (diesel only) (2 chimes)
-
Water in fuel (diesel only) ( 2 chimes)
If the ignition switch is turned to the run/start/acc position and the driver's door is closed, then opened, the warning chime is defeated. This allows the
doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the "OFF" position,
then normal function will be restored. (Highline CTM only).
Compass Mini-Trip Computer (CMTC)
This system, located in the overhead console, displays information on outside temperature, compass direction and trip information.
Compass And Temperature Display
This display provides the outside temperature in °F or °C and one of eight compass readings to indicate the direction of the vehicle is facing. Trip
Odometer (ODO)--Shows the distance traveled in miles or km since the last reset.
Average Fuel Economy (AVE ECO)
Shows the average fuel economy in MPG (miles per gallon) or L/100 Km since the last reset.
Distance to Empty (DTE)
Shows the estimated distance that can be traveled with the fuel remaining in the tank. This level calculated using the MPG multiplied by the Fuel
Tank Level.
Elapsed Time (ET)
Shows the accumulated ignition on time whenever the CMTC is powered up until a reset takes place.
Step Button
Press this button to cycle through all the mini-trip computer displays.
US/M Button
Press this button to convert all vehicle displays from US to Metric and vice versa.
To Reset the Display
Press the Step and US/M buttons simultaneously for at least two seconds and all resettable conditions will be reset. This will occur only if a
resettable function (AVG ECO, ECO, ET) is currently being displayed.
Automatic Compass Calibration
This compass is self calibrating which eliminates the need to manually activate the switches on the compass. When the vehicle is new, the compass
may appear erratic and the CAL symbol will be displayed. Calibration is automatically detected when the vehicle is drive in a circle at a constant
speed between 5 and 11 mph. The diameter of circle should be between 30 and 90 feet, Calibration should take place in an area free of metal and
metallic objects and away from power lines. When the calibration process is completed, the CAL light will go OFF and the compass will function
normally.
