Instrument cluster, general
The instrument cluster notifies the driver of all dynamic and static driving conditions as well as about the current condition of the systems installed in the vehicle. In the event of faulty vehicle functions or functions relevant to safety, corresponding warnings are issued via the instrument cluster.
The following displays are incorporated in the instrument cluster in order to be able to convey information to the driver:
- Permanent displays (e.g. vehicle speed, rotational speed, tank contents)
- Indicator lamps (green, yellow or blue) (e.g. turn signals, high beams)
- Warning lamps (red) (e.g. coolant level, brake fluid level)
- Multifunction display (e.g. outside temperature indicator, travel distance display)
This document contains the following functions:
- Function sequence for activate instrument cluster
- Function sequence for indicator lamp test
The following functions are also possible; they are described in separate documents:
- Indicator/warning messages
- Display operating conditions
- Comfort displays
- Trip computer
- Workshop level settings
Function sequence for activate instrument cluster
For the following events the background illumination of the multifunction display in the instrument cluster is activated:
- Unlocking vehicle using radio or infrared
- Opening or closing driver door
- Change in circuit 15C status
The following events activate the background illumination of the multifunction display and the scale illumination of the instrument cluster:
- Standing lights ON (up to 31.05.2012 with scale illumination)
- Circuit 15R ON
After switching off circuit 15R the instrument cluster remains active for t = 40 s. If a fault exists, this time is extended to t = 120 s.
Additional function requirements for indicator lamp test
- Terminal 15 ON
The circuit 15 status is sent by the electronic ignition lock control unit to the instrument cluster via the interior CAN.
Function sequence for indicator lamp test
The indicator lamp test serves the function test of certain warning lamps and indicator lamps in the instrument cluster. The instrument cluster carries out this test automatically each time circuit 15 is switched on.
The function of the following warning and indicator lamps is checked during the indicator lamp test:
- Fuel reserve indicator lamp
- Brake fluid and parking brake warning lamp
- Seat belt warning lamp
- Supplemental restraint system indicator lamp
- Antilock brake system indicator lamp
- ESP®/ASR OFF warning lamp
- Electronic Stability Program warning lamp
- Brake system warning lamp
- COLLISION PREVENTION ASSIST warning lamp (with code 258 (COLLISION PREVENTION ASSIST PLUS))
- Coolant temperature warning lamp
- Engine diagnosis indicator lamp
- DISTRONIC warning lamp (with code 233 (DISTRONIC PLUS))
- Tire pressure monitor warning lamp (with code 475 (Tire pressure monitor))
The indicator lamp test is terminated when the engine is started.
The function of the following indicator lamps is not checked:
- Left turn signal indicator light
- Right turn signal indicator light
- High beam indicator lamp
- Preglow indicator lamp (on diesel engine)
- Rear fog lamp indicator lamp
- Standing lights indicator lamp (as of 01.06.2012)
- ESP SPORT indicator lamp (with engine 157)
- Low beam indicator lamp
Detailed information on the warning and indicator lamps is available in a separate document.
