RefuelingThe engine oil level has dropped to a critical level.
A warning tone also sounds.XCheck the oil level ( Y page 239).XIf necessary, add the engine oil ( Y page 240).XHave the engine checked for leaks if engine oil has to be added
more often than usual.
Information on approved engine oils can be obtained from any qualified specialist workshop
or on the Internet at http://www.mbusa.com (USA only).
! The oil level is too low. Avoid long journeys with too little engine oil. There is a risk of
engine damage.
The display messages and the corresponding symbol that indicate that the oil level is too
low must not be ignored.

Determining the maximum load
The following steps have been developed as required of all manufacturers under Title 49, Code
of U.S. Federal Regulations, Part 575 pursuant to the "National Traffic and Motor Vehicle
Safety Act of 1966".XStep 1: Locate the statement "The combined weight of occupants and cargo should never
exceed XXX kg or XXX lbs." on your vehicle's Tire and Loading Information placard.XStep 2: Determine the combined weight of the driver and passengers that will be traveling
in your vehicle.XStep 3: Subtract the combined weight of the driver and passengers from XXX kilograms or
XXX lbs.XStep 4: The resulting figure equals the available amount of cargo and luggage load capacity.
For example, if the "XXX" amount equals 1400 lbs and there will be five 150 lbs passengers
in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 -
750 (5 x 150) = 650 lbs).X Step 5: Determine the combined weight of luggage and cargo being loaded on the vehicle.
For reasons of safety, that weight must not exceed the available cargo and luggage cargo
capacity calculated in step 4.XStep 6 (if applicable): If you intend to tow a trailer behind your vehicle, the load on the
trailer is transferred to your vehicle. Consult this Operator's Manual to determine how this
reduces the available cargo and luggage load capacity of your vehicle ( Y page 284).
The following table shows examples of how to calculate total and cargo load capacities with
varying seating configurations and number and size of occupants. The following examples use
a cargo limit of 1500 lbs (680 kg). This is for illustration purposes only. Make sure you
always use the actual load limit for your vehicle stated on the vehicle's Tire and Loading
Information placard ( Y page 281).
