WARNING Danger of burns when open‐
ing the hood
If you open the hood when the engine has
overheated or during a fire in the engine com‐
partment, you could come into contact with
hot gases or other escaping operating fluids.
#
Before opening the hood, allow the
engine to cool down.
#
In the event of a fire in the engine com‐
partment, keep the hood closed and call
the fire service.

WARNING Risk of scalding from hot
coolant
The engine cooling system is pressurized,
particularly when the engine is warm. If you
open the cap, you could be scalded by hot
coolant spraying out.
#
Let the engine cool down before open‐
ing the cap.
#
When opening the cap, wear protective
gloves and safety glasses.
#
Open the cap slowly to release pres‐
sure.
Allow the engine and the engine cooling system
to cool down before checking the coolant level or
refilling coolant.
* NOTE Paintwork damage due to coolant
If coolant gets on painted surfaces, the paint‐
work can be damaged.
#
Add coolant carefully.
#
Remove spilled coolant.
Checking the coolant level
Example: coolant expansion reservoir
#
Park the vehicle on an even surface.
#
Open the hood (
→
page 174).
#
Slowly turn the coolant expansion reservoir
cap 1 half a turn counter-clockwise and
allow excess pressure to escape.
#
Turn coolant expansion reservoir cap 1 fur‐
ther and remove it.
#
Check the coolant level.
There is enough coolant in coolant expansion
reservoir if the coolant reaches the MAX
mark.
Adding coolant
#
Refill the coolant to the MAX mark on the
coolant expansion reservoir.
Only use coolant approved by Mercedes-Benz to
avoid damaging the engine cooling system.
#
Replace coolant expansion reservoir cap 1
and tighten in a clockwise direction.
#
Start the engine.
#
After approximately five minutes, switch off
the engine again and allow it to cool down.
#
Check the coolant level again and add coolant
if necessary.
