mend that you check the following items
regularly (for example: weekly, when re-
fueling, or before any long journey):
• Engine oil level - Check the engine oil
level using the engine oil dipstick. Fur-
ther information about engine oil level
measurement can be found in the vehi-
cle Operator’s Manual.
• Coolant level - Please refer to the Op-
erator’s Manual for the correct proce-
dure to check the coolant level.
• Brake fluid level - If brake fluid has to
be added, see an authorized Mer-
cedes-Benz Center to determine the
cause, e.g. leaks or worn brake pads.• Windshield washing system - If the
washer fluid level drops below 1/3, the
windshield washer fluid level warning
lamp will illuminate. Add washer fluid
mixed with Mercedes-Benz windshield
washer solvent/concentrate, test
function and check wiper blades.
• Check lights
• Tire condition and pressures –
Check at least every other week.
