To retain the effectiveness of the "flat-blade" wiper blades, it is advisable to: - handle them with care, - clean them regularly using soapy water, - not use them to hold a sheet of cardboard against the windscreen, - replace them at the first signs of wear.
Do not cover the rain sensor, linked with the sunshine sensor and located in the centre of the windscreen behind the rear view mirror. Switch off the automatic wiping when using an automatic car wash. In winter, it is advisable to wait until the
windscreen is completely clear of ice before activating the automatic wiping.
This position allows the wiper blades to be lifted for winter parking, cleaning or replacement without damaging the bonnet. In the minute following switching off of the ignition, any action on the wiper stalk positions the wipers ver tically. To park the wipers after this has been done,
switch on the ignition and operate the wiper stalk.

Changing the coolant
The coolant does not have to be changed.
Fluid specifi cation
The coolant must conform to the manufacturer's recommendations.
Screenwash fluid level
Fluid specifi 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 par ts 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 "MA X" 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 par ticle 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.
