Instrument Cluster (IC)
Instrument Cluster (IC)
Expedition
Navigator
The Instrument Cluster (IC) contains gauges, informational indicators, warning indicators and message center indicators that are designed to provide the driver with system status and to alert the driver that certain conditions exist in the vehicle.
The IC uses a 2-line display for display of basic informational items such as the odometer and trip odometer and for the message center display information.
All indicator lamps and warning indicator lamps are LEDs, which are not replaceable.
MyKey(TM)
The MyKey(TM) feature allows the customer to program a restricted driving mode that is tied to one or more keys known as a MyKey(TM). When a MyKey(TM) is in use, the IC provides the following functions:
- At beginning of vehicle start up, as part of the welcome strategy, the message center greets the MyKey(TM) driver with MYKEY ACTIVE DRIVE SAFELY displayed in the message center. If the MyKey(TM) speed limiter feature is turned on, the message center also displays SPEED LIMITED TO 80 MPH (or 130 km/h).
- The IC continuously provides a periodical Belt-Minder(R) warning chime until the driver and passenger safety belts are buckled. When the Belt-Minder(R) is issued, the ACM is muted and the message center displays BUCKLE UP TO UNMUTE RADIO.
- If the MyKey(TM) speed limiter feature is turned on and the vehicle speed approaches 130 km/h (80 mph), the message center displays VEHICLE SPEED 80 MPH MAX along with a chime.
- If the MyKey(TM) speed limiter feature is turned on and the vehicle speed approaches 120 km/h (75 mph), the message center displays VEHICLE NEAR TOP SPEED along with a chime.
- If the speed warning is selected at one of the pre-set values (75, 90, 105 km/h [45, 55, 65 mph]) and the vehicle approaches the pre-set speed, the message center displays CHECK SPEED DRIVE SAFELY along with a chime.
- If the traction control always on feature is turned on and the MyKey(TM) driver presses the traction control switch to disable traction control, the message center displays ADVTRAC ON MyKey(TM) SETTING.
- At 120 km (75 miles) to empty, the IC illuminates the low fuel indicator (if equipped) and the message center displays 75 MILES TO EMPTY along with a chime
- MyKey(TM) mileages driven by the MyKey(TM) user can be found in the INFO display and in the system check function of the message center.
- The number of MyKey(TM) programmed and admin keys can be found in the system check function of the message center.
- The parking aid, Blind Spot Information System (BLIS(TM)) with Cross Traffic Alert (CTA) (if equipped) and collision avoidance (if equipped) warning menus are disabled in the message center to force these features always on.
When an admin key is in use, the IC provides the following functions:
- The message center provides a menu that guides the user to create a MyKey(TM). When the maximum MyKey(TM) limit is reached, the MyKey(TM) creation menu is no longer available.
- The message center provides menus for setting 4 optional MyKey(TM) features:
- MyKey(TM) 80 MPH speed limiter
- MyKey(TM) pre-selected speed warning
- MyKey(TM) radio volume limiter
- AdvanceTrac(R) on/off
- The message center provides a menu to clear all MyKey(TM) programmed keys at once.
- MyKey(TM) mileages driven by the MyKey(TM) user can be found in system check function of the message center.
- The number of MyKey(TM) and admin keys can be found in the system check function of the message center.
Refer to Anti-Theft - Passive Anti-Theft System (PATS) Anti-Theft - Passive Anti-Theft System (PATS) for additional information on the MyKey(TM) features.
Gauges
Gauges provide information to the driver indicating the status of systems. The systems that use gauges are as follows:
- Charging system
- Engine coolant temperature
- Engine oil pressure
- Engine rpm
- Fuel level
- Vehicle speed
Informational Indicators
Informational indicators provide information to the driver of conditions that exist in the vehicle. The indicators include:
- Turn signal
- High beam
- Speed control
- Anti-theft
- Traction assist
- Malfunction Indicator Lamp (MIL)
Warning Indicators
Warning indicators provide information to the driver of conditions that could potentially cause personal injury or alter vehicle performance. The systems that use warning indicators include:
- ABS
- Brake system (indicating low brake fluid, parking brake applied or other ABS brake system concerns)
- Safety belt buckle status
- Supplemental Restraint System (SRS)
- TPMS
- Powertrain
Message Center Indicators
Message center indicators illuminate in the message center and replace the typical indicator and warning lamps and use the same iconic representation that were previously viewed as indicators or warning indicators in the IC. The systems that use message center indicators include:
- Powertrain malfunction
- Transmission (wrench)
- Electronic Throttle Control (ETC) (wrench)
- 4X4 (wrench)
- Charging (battery)
- Engine oil pressure
- Engine over-temperature (failsafe)
- Low fuel
- Low windshield washer fluid
- Tow haul
- Four-Wheel Drive (4WD)
- 4X4 LOW
- 4X4
- 4X4 AUTO
- Door ajar
Hardwired Inputs
The hardwired inputs are provided from the following systems or components:
- Ambient temperature sensor (if equipped)
- Engine oil pressure switch
- Fuel level
- Low washer fluid switch
- Message center switch
Messaged Inputs
Module messaging has significantly increased over time and is slowly becoming the standard for sending and receiving information required to operate the IC. For a complete list of module messages with the message origination sources, refer to Module Communications Network Description and Operation.
The status and information messages that the IC requires from other vehicle systems are as follows:
- Vehicle speed
- Engine temperature
- Engine rpm
- ABS
- 4WD
- Transmission range
- O/D status
- TPMS
- SRS
- Brake fluid level
- Parking brake status
- Engine emission system
- ETC
