Checking levels
There are two marks on thedipstick:A= maximum

Dipstick
Brake fluid level

The brake fluid level should be close to the
"MA X" mark. If it is not, check the brake pad
w
ear. If a level drops si
gnificantly, have the corresponding system checked by a CITROËN dealer or a
qualified workshop.
Check all of these levels re
gularly and top them up if necessary, unless other wise indicated.
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns).
Oil level
The check is carried out either when the ignition is switched on using the oil level indicator on the instrument panel, or using the
dipstick.
This manual check will only be correct if the
vehicle is on level ground and the engine has
been off for more than 30 minutes.
It is normal to top up the oil level between two ser vices (or oil changes). CITROËN recommends that you checkthe level, and top up if necessary, every 3 000 miles (5 000 kms). After topping up the oil, the check whenswitching on the ignition with the oillevel indicator in the instrument panelis not valid during the 30 minutes after topping up.

OT4 standard.


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.
In addition, as the cooling system is pressurised, wait at least one hour after switching off the engine before carrying out anywork.
To avoid any risk of scalding, unscrew the cap by two turns to allow the pressure to drop.
When the pressure has dropped, remove thecap and top up the level.
Changing the coolant
The coolant does not have to be changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.
