Coolant level
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and
systems, the applicable laws and regulations
must be observed.
Checking
1. Let the engine cool.
2. Turn the lid of the coolant reservoir slightly
counterclockwise to allow any excess
pressure to dissipate, then open it.
General information
The vehicle has two coolant reservoirs that are
located in the engine compartment.
To ensure the operational reliability of the vehi‐
cle, always check the coolant level of both
coolant reservoirs.
3. Open the coolant reservoir lid.
4. The coolant level is correct if it lies be‐
tween the minimum and maximum marks
in the filler neck.
Not all commercially available additives are
suitable for the vehicle. Information about suit‐
able additives is available from a dealer’s serv‐
ice center or another qualified service center or
repair shop.
