gradually diminished. Regularly check the
oil level, and top up or have it replaced as
needed.

WARNING
If engine oil comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Make sure that engine oil is not spilled next
to the filler neck. Let the engine cool down
and thoroughly clean the engine oil off the
components before starting the engine.
! The alternator is located below the engine
oil filler neck.Ife ngine oil spills onto the
alternator, there is a dange rofalternator
damage. Be very careful when adding
engine oil. H
Environmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
! Do not add too much oil. adding too much
engine oil can result in damage to the
engine or to the catalytic converter. Have
excess engine oil siphoned off.
! Do not use any additives in the engine oil.
This could damage the engine.

WARNING
The engine cooling system is pressurized,
particularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
Only check the coolant level and/or fill the
coolant if the vehicle is on a level surface and
the engine has cooled down. The coolant
temperature must be below 122 ‡ (50 †).
! Check the engine cooling and heating
system regularly for leaks.
If a large quantity of coolant is lost, have
the cause traced and rectified at a qualified
specialist workshop. 244
