MOBILITY In the engine compartment
150
Service Centre can provide details of which addi-
tives are suitable.
Use only suitable additives, otherwise the
engine could incur damage. As these
additives are hazardous to health, observe the
notes on the containers.<
When disposing of coolant additives, com-
ply with the relevant environmental pro-
tection regulations.<
Coolant temperature
If the coolant and hence the engine overheats, a
warning light lights up, see page 175.
Checking coolant level
Do not open up the cooling system while
the engine is hot, otherwise you may scald
yourself on the escaping coolant steam.<
Do not open the engine compartment lid until
the engine has cooled down.
The coolant level is correct if it is between the
Min. and Max. marks.
Topping up
1. Turn the cap on the expansion tank slightly
anticlockwise until it starts to open, then
allow the pressure to escape before opening
it fully.
2. Slowly top up to the correct level but do not
overfill.
3. Turn the cap.
Have the cause of coolant loss rectified as soon
as possible.
