The text messages and symbols in this section of the display are not shown permanently.

Instrument cluster: Further information

Time intervals (e.g. )

The various symbols for the time intervals -arrow- ⇒ fig. 146 appear when you change the settings.

The symbol indicates that the warning tone has been switched off.

... The text message ... (three white dots) appears if a setting made with the control lever cannot be implemented. There can be several reasons for this:

• • You have pulled the control lever towards you to resume the programmed cruising speed, without a target speed having been set.
• • The control lever has been pushed up / down to increase / reduce the speed, without a target speed having been set.
• • The control lever has been pushed up / down to increase / reduce the speed, but the resulting speed would be outside the range of 30 to 200 km/h.

ACC deactivation

The message ACC deactivation sometimes appears on vehicles with a manual gearbox. If you press the clutch pedal for longer than about 20 seconds, the adaptive cruise control will be automatically deactivated and a warning tone will sound.

ACC not available

The text message ACC not available will appear if, for example, the brakes are overheated. The adaptive cruise control will then temporarily not be available. This is indicated by a warning tone.

ACC not available!

The text message ACC not available! appears if a malfunction should occur. The adaptive cruise control will then be switched off. This is indicated by a warning tone. Have the system checked by a qualified workshop.

ACC sensor blocked!

The text message ACC sensor blocked! appears if the ACC system can no longer detect objects reliably. The adaptive cruise control will then be switched off. This is indicated by a warning tone. The ACC sensor is obstructed by dirt or foreign objects (e.g. leaves or snow). Clean the sensor to restore the function, fig. 136.

Engine speed !

On vehicles with manual gearbox, the text message Engine speed ! will appear if the driver does not change gear in time when the adaptive cruise control accelerates or brakes the vehicle. The adaptive cruise control will automatically be deactivated if the engine speed is not maintained within the permissible range. This is indicated by a warning tone.

ESP activation

The text message ESP activation appears if the Electronic Stabilisation Programme (ESP) has intervened. In this case, the adaptive cruise control will automatically be switched off. This is indicated by a warning tone.

Speed (in km/h)

The target speed (in km/h) will appear in the display whenever it is stored or changed, “Setting the speed” and, “Setting a new speed”.

Speed range

The text message speed range appears if the current speed is too low to set or to maintain the target speed.

To set a target speed, the speed of the vehicle must be at least 30 km/h. The cruise control system switches off if the speed falls below 20 km/h.

If the speed exceeds 200 km/h (OVERRIDE), the system will remain active and will reduce the speed to 200 km/h once the driver stops accelerating.

ACC functionality limited

The text message ACC functionality limited appears if the ACC system does not detect any objects for an extended period. The distance to vehicles in front is not being controlled while the message is displayed. The ACC system is not deactivated, and so extra care should be taken! The text message ACC functionality limited can appear for the following reasons:

• • The ACC sensor is dirty. The ACC system is not responding or is not responding correctly to the vehicles in front!
• • You may be driving on a country road with no traffic and no clear roadside demarcation (e.g. safety barriers, traffic signs, trees). As soon as the system detects a vehicle, distance control is resumed and the text message disappears.

The ACC sensor is located inside the trim grille (front right), fig. 136. If the sensor is no longer functioning due to dirt or obstruction in this area, it should be cleaned.

Parking brake !

The text message Parking brake ! appears if the parking brake is operated. The adaptive cruise control will then be switched off. This is indicated by a warning tone.

Gear lever position !

On vehicles with manual gearbox the text message Gear lever position ! appears when no valid forward gear is selected, i.e. reverse gear or 1st gear is engaged or the gear lever is in the neutral position. Adaptive cruise control is not available when the lever is in these positions.

Shift lever position!

On vehicles with automatic gearbox the text message Shift lever position ! appears if the shift lever is moved to position N. Adaptive cruise control is not available when the lever is in this position.
