Mercedes-Benz ML320. Service manual - part 557

 

 

If oil is now topped up after 5 000 km (a), the remaining distance displayed is not extended as the curve is 
within the shaded area. The bonus B1 is nevertheless added internally and results in an extension of the service 
interval to slightly more than 15 000 km - provided the driving conditions remain the same or are more 
favorable. 

(The service interval of 15 000 km is always reached, however, even if the internal value were less.)

Example 4:  

Oil has been topped up after 5 000 km under unfavorable driving conditions (a) and the oil replenishment 
(bonus B1) detected internally. We now have two cases to consider: 

If the car continues to be driven under the same conditions (unbroken line), the remaining distance 
displayed is not extended as the curve is within the shaded area. 

The service interval in this case is nevertheless 15 000 km although the internal value is less. (The 
remaining distance displayed can always only be within the light area.) 

If the car continues to be operated under more favorable conditions (broken line), the value of the internal 
remaining distance slowly moves into the light area. Consequently, the service interval may be greater 
than 15 000 km.

MODEL 202 as of 1.8.99  

Display of service to be performed  

In addition to the various service displays, the service work to be performed (A or B) also appears. 

The service symbol (wrench) appears once or twice in the display for this purpose. 

The service symbol appears 

once for service A  

twice for service B .  

 A service A is always followed by a service B. 

Following a service B, the next service must be calculated taking into account the kilometer readings. If the 
distance of the current service interval is less than 22 000 km, the next service is service A, otherwise service B.

This calculation is now performed automatically in the instrument cluster (A1). 

The path of the service displayed A or B can be processed in the service sheet without the need for a 
calculation. 

 There is no external difference in the instrument clusters with and without the service display. 

If service A (one service symbol) is displayed, it is then necessary to ensure by means of the production date 
or the control unit identifier , that the vehicle in question is in fact a vehicle with service display . If this is 
not the case, the service must be determined as specified in the service sheet. 

The table below shows from which control unit identifier the instrument cluster features the service display: 

The control unit identifier can be read with the HHT under menu point Control unit version.

RISK OF INJURY CAUSED BY PINCHING OR JAMMING WHEN WORKING ON LOADED SPRINGS OR SPRING BODIES 
- AS00.00-Z-0001-01A 

Use only approved clamping devices; shield off hazard area if necessary. Inspect special tools for damage 
and proper operation (visual inspection). Wear protective gloves.
  

Risk of pinching and jamming body parts when working on pre-loaded components.  

When loosening or removing components that are under significant load, there is a risk of serious injury if 
non-approved if clamping devices are used. 

Safety instructions/precautions  

When conducting repair work on springs, spring bodies, spring-type actuators and other components under 
tension use approved clamping devices only . 

Spring compressor  

The spring compressor should never be clamped or released using an impact wrench. 

Check clamping devices  

The spindle must be undamaged and allow ease of movement.  

The clamping plates must not be deformed.  

Note arrangement of clamping plates to springs.  

If the device is damaged or malfunctioning, it must be returned to the manufacturer.  

 The coil diameter of the spring should match the groove in the clamping plate. 

Wear protective gloves during all operations. 

RISK OF INJURY. SKIN OR EYE INJURIES MAY RESULT WHEN HANDLING HOT OR GLOWING OBJECTS. - AS00.00-
Z-0002-01A 

Wear protective gloves, protective clothing and (where necessary) safety glasses.  

Risk of injury  

Unprotected contact with hot or glowing objects may cause severe burns to the skin and eyes. 

If glowing objects come into contact with water, hot steam or hot splashing water may result in severe skin and 
eye burns. 

Severe and possibly permanent injuries may result if hot or glowing objects come into contact with unprotected 
skin or eyes. 

 Fire may result if glowing objects come into contact with flammable materials or substances.
