234 Maintenance and care
Example: engine oil filler opening
Observe the information regarding approved
#
engine oil under "Operating fluids and capaci‐
ties" ( page 282).
/
Unscrew and remove the cap 1.
#
Top up engine oil.
#
Fit the cap 1 on the filler opening and
#
tighten.
When doing so, make sure that the cap
engages correctly.
If present, check the oil level using the oil dip‐
#
stick ( page 232).
/
In the case of vehicles without an oil dipstick,
#
check the oil level with the on-board com‐
puter after the next journey (
It is necessary to run the engine for an extended
period after each oil top up to correctly detect
the oil level. Fill level changes during oil top ups
may not be immediately visible. Depending on the
driving profile, the new oil level can only be dis‐
played after a driving time of up to 60 minutes.
If necessary, only top up the quantity of oil shown
in the instrument cluster display and check the
oil level again after the next journey.
Checking/topping up the coolant
& WARNING Risk of fire‑ and injury from
antifreeze
If antifreeze comes into contact with hot com‐
ponent parts in the engine compartment, it
may ignite.
Allow the engine to cool down before
#
you top up the antifreeze.
Check and top up the coolant only when the vehi‐
cle is stationary and in a horizontal position and
the engine has cooled down. The coolant temper‐
ature must be below 50°C.
page 231).
/
Coolant contains glycol and is therefore poison‐
ous.
#
Regularly check the engine cooling system and
the heating system for leaks. If there is a loss of
coolant, have the cause determined and rectified
in a qualified specialist workshop without delay.
Make sure that no antifreeze spills out
#
next to the filler opening.
Thoroughly clean the antifreeze from
#
component parts before starting the
vehicle.
& WARNING Risk of scalding from hot
coolant
If you open the cap, you could be scalded.
Let the motor cool down before opening
#
the cap.
When opening the cap, wear protective
#
gloves and safety glasses.
Open the cap slowly to release pres‐
#
sure.
& WARNING Risk of burns from hot com‐
ponent parts in the engine compartment
Certain component parts in the engine com‐
partment can be very hot, e.g. the engine, the
cooler and parts of the exhaust system.
Allow the engine to cool down and only
#
touch component parts described in the
following.
Observe the information under "Operating flu‐
ids and capacities" (
* NOTE Paintwork damage due to coolant
If coolant gets on painted surfaces, the paint‐
work can be damaged.
Add coolant carefully.
#
Remove spilled coolant.
