Schedule of ongoing maintenance

The suggested recommendations assume that the owner performs the vehicle maintenance procedures independently, as opposed to the work performed at the service station of the representative office of Mercedes-Benz. Although this schedule is based on the manufacturer's recommendations, the intervals between most procedures can be shortened at the discretion of the vehicle owner, such as checking and changing lubricants and fluids at intervals to maximize engine or drive life. In addition, if the owner of the car is interested in keeping it in a state of maximum readiness for use in case of a possible resale, many procedures can be performed more frequently. The compilers of this Guide can only welcome such an initiative.

The initial service and inspection of a new vehicle must be carried out by a Mercedes-Benz Dealership in order to fulfill the terms of the warranty. This service is provided free of charge.

Every 160,000 km or every 4 years

• Replace spark plugs on petrol models.

Procedures to be performed in accordance with standard Maintenance Work Lists (according to ASSYST indication)

List A: The procedure is performed if the mileage since the last maintenance according to list B is less than 22,000 km.


List B: The procedure is performed if the mileage since the last maintenance according to list B is over 22,000 km.

Attention! Primary maintenance is carried out according to list B (full scope of work)!

List A

Car interior, windshield wipers

• Check the correct operation of the following devices:
• Sound and light signaling devices, turn indicators / emergency signaling;
• Control / indicator lamps, lighting elements and interior lighting devices;
• Outdoor lighting fixtures;
• Windscreen wipers;
• windshield washers (including headlight washers).
• Check up a condition and serviceability of functioning of seat belts.
• Reset the scheduled maintenance interval counter on the instrument panel (see Section Active warning system about the timing of scheduled maintenance (ASSYST)).

Wheel assemblies and brake mechanisms

• Through the openings in the disks of the right wheels, evaluate the residual thickness of the friction linings of the brake pads (see chapter Brake and auxiliary systems).
• Through the opening in the disk of the right front wheel, evaluate the residual thickness of the brake disk (see chapter Brake and auxiliary systems).
• Assess the degree of wear and general condition of the tires, measure the remaining depth of the tread pattern, if necessary, change / rotate the wheels (see Section Checking the condition of tires and their pressure, designation of tires and wheel rims, wheel rotation).
• Check tire inflation pressure (see Specifications), make appropriate adjustments if necessary.
• Check the inflation pressure of the spare tire (see Specifications).

Engine compartment for G400 CDI diesel models

Attention! Be careful when performing work in the engine compartment - the cooling system fan may operate for about 30 seconds after the engine is turned off!

Attention! In electronic ignition systems, very high voltage is generated! Be careful, observe all necessary precautions when servicing any system components, including not only the main (ignition module, coil and explosive wiring), but also related ones, such as spark plug connectors, a tachometer and other connected diagnostic equipment. Particular care should be taken when the engine is running, during its start, with the ignition on (key in position 2) and when turning the crankshaft by hand. Persons with an implanted pacemaker must not be allowed to service the components of the ignition system!

• Check brake fluid level (see Section Checking fluid levels, leak control).
• Check the washer fluid level (see Section Checking fluid levels, leak control).
• Check the level and assess the condition of the engine coolant (see Section Checking the functioning of the cooling system and frost resistance of the coolant, changing the fluid).
• Change engine oil and oil filter (see Section Changing the engine oil and oil filter).
• Lubricate the elements of the lock and hood hinges.

List B

Interior, headlights and wipers

In addition to the procedures listed in List A:

• Replace cabin filter (see Section Cabin filter replacement).
• Check the correct adjustment of the tilt of the optical axes of the headlights, if necessary, make the appropriate adjustment (see chapter Onboard electrical equipment).
• Replace front wiper blades (see Section Replacing wiper blades).
• Check the electrolyte level in the battery (see chapter Engine Electrical Systems), - release models from 12.2002.

Wheel assemblies and brakes

• Remove the wheels and measure the remaining thickness of the pads and discs of the front and rear brakes (see chapter Brake and auxiliary systems).
• Assess the degree of wear and general condition of the tires, measure the remaining depth of the tread pattern, replace if necessary (see Section Checking the condition of tires and their pressure, designation of tires and wheel rims, wheel rotation).
• Rotate the wheels (see Section Checking the condition of tires and their pressure, designation of tires and wheel rims, wheel rotation).
• Check tire inflation pressure (including spare wheel), make appropriate adjustments if necessary.
