Power Steering Fluid Level; Coolant Level; Changing The Coolant - CITROËN DS4 Owner's Handbook Manual

Power steering fluid level

The power steering fluid level should
be close to the "MAX" mark. Unscrew
the cap, with the engine cold,
to check the level.

Coolant level

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.

Changing the coolant

The coolant does not have to be changed.
