Introduction
The presentation of the driver information uses the following supports
- Instrument panel (instruments, liquid crystal display, warning lamps)
- Multifunction screen (alerts, information, etc)
- Air conditioning panel
- Buzzer incorporated in the switch module under the steering wheel
- Electroluminescent diode on button
- Radio speakers for parking assistance (according to equipment)
- Seat belt not fastened warning lamps
Information is managed as a function of priorities and type of support
Driver information can be broadcast simultaneously on more than just one information support
Example: STOP + coolant temperature alert warning lamps on: triggers two types of warning, a warning on the multifunction display and a sound emitted by the switch buzzer under the steering wheel
The information supports on the instrument panel present the following components
- The alert and information warning lamps
- A liquid crystal display including a maintenance indicator, an oil level indicator and odometers, cruise control, speed limiter, water in diesel fuel detection, pre-heating indicator
- The dials: speedometer, rev counter, coolant temperature, fuel level
- Adjustment buttons (brightness, partial odometer and maintenance zero reset)
The instrument panel communicates with the other ECUs of the COMFORT CAN and has autodiagnostic functions
The technician can carry out the following operations on the instrument panel; using a diagnostic tool
- Reading of the data
- Writing of the data
- Actuator tests and output commands
- Setting certain types of information to zero
(1) instrument panel (instruments, liquid crystal display, warning lamps)
(2) remote display (according to equipment)
(3) multifunction screen (alerts, information, etc)
(4) air conditioning panel
(5) buzzer incorporated in the switch module under the steering wheel
"a" driver front seat belts not fastened warning lamps
"b" passenger's airbag deactivation
"c" passenger front seat belts not fastened warning lamps
Alert priority levels
The management of the presentation of the alerts is defined by levels of priority regardless of the information support (*)
The priority levels are managed by the BSI1, permitting a classification between the different types of information dealt with by the 2 following supports
- The multifunction display
- The audible warning integrated in the switching module under the steering wheel
Note(*) except specific cases where windows are displayed on the multifunction screen
| priority number | associated sound | description of the priority |
|---|---|---|
| P0 | yes | prompting message due to an emergency situation requiring immediate driver intervention |
| P1 | yes | serious alert due to a vehicle malfunction necessitating an immediate stop |
| example: engine oil pressure alert | ||
| P2 | no OK | change of status of a function caused by the vehicle |
| example: ESP in adjustment | ||
| P3 | yes | serious alert requiring immediate driver intervention |
| example: handbrake detection | ||
| P4 | no OK | change of status of a function triggered by the driver |
| example: modification of the suspension mode | ||
| P5 | yes | alert requiring driver intervention |
| example: seat belt not fastened detection | ||
| P6 | yes | preventive alert |
| example: low fuel level, airbags fault alert | ||
| P7 | yes | minor alert |
| example: screenwash low, bulb blown alert | ||
| P8 | no OK | operating mode message |
| example: door open at a speed below 10 km/h | ||
| P9 | yes | alert due to an omission requiring driver intervention |
| example: dipped headlamps left on | ||
| P10 | yes | alert due to an omission requiring driver intervention |
| example: key left in ignition | ||
| P11 | no OK | information on the number of rear seat belts fastened |
An alert of a higher level interrupts an alert of a lower level
An alert of a lower level is taken into account when the alert of a higher level has completed its current cycle
Alerts on the same level of priority appear consecutively
NoteThe alerts appear in ascending order of priority number (from P0 to P11)
