Changing the coolant
The coolant does not have to be changed.
Fluid speci cation
The coolant must conform to the
manufacturer's recommendations.
Screenwash fluid level
Fluid speci cation
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with water.
Take care when carrying out checks
under the bonnet as some parts of the
engine can be very hot (risk of burns).
Coolant level
Top up the level when necessary.
The coolant level should be close
to the "MAX" mark but should never
exceed it.
When the engine is warm, the
temperature of the coolant is regulated by the
fan. This can operate with the ignition off.
On vehicles which are fitted with a particle
emission filter, the fan may operate after
the vehicle has been switched off, even if
the engine is cold.
In addition, as the cooling system is pressurised,
wait at least one hour after switching off the
engine before carrying out any work.
To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top up the level.
