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 country provisions
must be observed.
Overview
Depending on the engine installation, the cool‐
ant reservoir is located on the right side or the
left side of the engine compartment.
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
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.
Safety information
3. Open the coolant reservoir lid.
WARNING
4. The coolant level is correct if it lies be‐
tween the minimum and maximum marks
in the filler neck.
With the engine hot and the cooling sys‐
tem open, coolant can escape and lead to
scalding. There is a risk of injury. Only open
the cooling system with the engine cooled
down.◀

Additives are harmful and incorrect addi‐
tives can damage the engine. There is a risk of
injury and risk of property damage. Do not al‐

tives only.◀
