Detailed measurement
The concept In the detailed measurement the engine oil
level is checked and displayed via a scale.
Gasoline engine:
If the engine oil level reaches the minimum
level, a check control message is displayed.
Diesel engine:
During the measurement, the idle speed is in‐
creased somewhat.
General information
A detailed measurement is only possible with
certain engines.
Requirements▷Vehicle is on level road.▷Selector lever in selector lever position N
or P and accelerator pedal not depressed.▷Engine is running and is at operating tem‐
perature.

CoolantVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Information WARNING
With the engine hot and the cooling sys‐
tem open, coolant can escape and lead to
burns. There is risk of injuries. Only open the
cooling system with the engine cooled down.◀
WARNING
Additives are harmful and incorrect addi‐
tives can damage the engine. There is risk of
injuries and risk of property damage. Avoid the
contact of articles of clothing, skin or eyes with
additives. Do not swallow any additives. Use
suitable additives only.◀
Coolant consists of water and additives.
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.
Coolant level
General information
Vehicles with gasoline engine feature two
cooling circuits. Always check the coolant lev‐els of both coolant reservoirs and refill as
needed.
The coolant level is indicted using minimum
and maximum markings. Depending on the
coolant reservoir, the minimum and maximum
markings are located at different locations.
Overview
Opening the hood, refer to page 272
Depending on the engine installation, the cool‐
ant reservoir is located on the right side or the
left side of the engine compartment, refer to
page 271.

neck1.Let the engine cool.2.Turn the lid of the coolant reservoir slightly
counterclockwise to allow any excess
pressure to dissipate, then open it.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.
