Automatic transmission fluid level
The transmission has a permanent fill of automatic 
transmission fluid.
Regular automatic transmission fluid level checks and 
changes are not required. For this reason the dipstick is 
omitted.
If you notice fluid leaks or gear shifting malfunctions, 
have your authorized Mercedes-Benz Center check the 
transmission fluid level.Coolant level
To check the coolant level, the vehicle must be parked 
on level ground and the engine stopped.
Check coolant level only when coolant is cold.
The coolant level should reach the black top part of the 
reservoir.

coolant concentration or bring it back up to the proper 
level.
To provide the important corrosion protection, the 
solution must be at least 45% anticorrosion / antifreeze 
(equals a freeze protection to approx. - 22 
°F [- 30 
°C]). If 
you use a solution that is more than 55% anticorrosion /
antifreeze (freeze protection to approx. - 49 
°F [- 45
°C]), 
the engine temperature will increase due to the lower 
heat transfer capability of the solution. Therefore, do not 
use more than this amount of anticorrosion / antifreeze.
If the coolant level is low, water and MB anticorrosion /
antifreeze should be used to bring it up to the proper 
level (have cooling system checked for signs of leakage). 
Please make sure that the mixture is in accordance with 
label instructions.
The water in the cooling system must meet minimum 
requirements, which are usually satisfied by normal 
drinking water. If your are not sure about the water 
quality, consult your authorized Mercedes-Benz Center.
Anticorrosion / antifreeze
Your vehicle contains a number of aluminum parts. The 
use of aluminum components in motor vehicle engines 
necessitates that anticorrosion / antifreeze coolant used in such engines be specifically formulated to protect the 
aluminum parts. (Failure to use such anticorrosion /
antifreeze coolant will result in a significantly 
shortened service life.)
Therefore the following product is strongly 
recommended for use in your car: Mercedes-Benz 325.0 
Anticorrosion / Antifreeze Agent.
Before the start of the winter season (or once a year in 
the hot southern regions), you should have the 
anticorrosion / antifreeze concentration checked. The 
coolant is also regularly checked each time you bring 
your vehicle to your authorized Mercedes-Benz Center 
for service.
