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 any faulty or safety-relevant vehicle functions, various warnings are displayed on the instrument cluster.
The following displays are incorporated into the instrument cluster in order to be able to convey information to the driver:
- Permanent displays (e.g. for speed, rotational speed, tank content)
- Indicator lamps (green, yellow or blue) (e.g. for turn signals, high beams)
- Warning lamps (red) (e.g. for coolant level, brake fluid level)
- Multifunction display (e.g. for outside temperature, display of the travel distance)
The function description for the "Instrument cluster (KI) function" 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 information:
- Control/warning messages, function
- Display operating conditions, function
- Comfort displays, function
- Trip computer, function
- Settings on workshop level, function
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
- Driver door opened
- Change of 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
- Circuit 15R ON
After switching off circuit 15R, the instrument cluster remains active for t = 30 s. If a fault exists this time is increased to t = 120 s.
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 circuit 15 status is sent by the electronic ignition lock control unit over the interior CAN to the instrument cluster.
The following warning and indicator lamps are activated during the indicator lamp test:
- Fuel reserve indicator lamp
- Brake fluid and parking brake indicator 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 (up to 28.11.2014 with CODE 258 (Collision Prevention Assist), as of 01.12.2014 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 (premium), Schrader))
The indicator lamp test is terminated when the engine is started. The following indicator lamps are not tested:
- 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
- Front fog lamp indicator lamp (with CODE 498 (Japan version) or without CODE 615 (Bi-xenon headlamp unit with integrated curve illumination) and without CODE 616 (Bi-xenon headlamp unit with integrated asymmetric curve illumination) and without CODE 621 (Intelligent Light System (left-hand traffic)) and without CODE 622 (Intelligent Light System (right-hand traffic)))
- Low beam indicator lamp
Detailed information on the warning and indicator lamps can be found in the information "Control/warning messages, function".
