All operations on the hydraulic suspension circuit must be performed in conformity with the following requirements and regulations:
Authorities competent in matters of health:
- Accident prevention.
- Environmental protection.
WARNING: Operations should be carried out by specialised personnel who have had training in the safety requirements and precautions to
be taken.
Safety requirements.
ESSENTIAL: In view of the special features of the hydraulic suspension system, observe the requirements below, before undertaking any
repair.
IMPERATIVE: Depending on the operation to be carried out, respect the requirements for supporting and securing the vehicle.

HYDRAULICS
SAFETY REQUIREMENTS: ACTIVE SUSPENSION WITH VARIABLE DAMPING
During the operation.
Wait for the pressure in the hydraulic circuit to fall fully before disconnecting the unions on the following components (risk of sudden sinking of the
vehicle):
- Built-in Hydro-electronic Interface (BHI).
- Front suspension cylinder.
- Rear suspension cylinder.
- Front stiffness regulator.
- Rear stiffness regulator.
- Suspension pressure sensors.
IMPERATIVE: Do not operate on the hydraulic circuit without making the pressure drop (see corresponding operation).
Engine running.
Do not operate on the hydraulic suspension circuit.
Always remain out of range of any possible projections of fluid, as these could cause serious injuries.
NOTE:In the event of contact of LDSfluid with the eyes, rinse them with copious amounts of water and seek specialist advice.
NOTE:In the event of lengthy contact of LDSfluid with the skin, wash it with soap and water.
WARNING: After the engine has stopped, wait 30 seconds before commencing any operation.

SAFETY REQUIREMENTS: ACTIVE SUSPENSION WITH VARIABLE DAMPING
IMPERATIVE: Do not remain underneath the vehicle during an operation to adjust vehicle heights or during actuator (electrovalve) tests.
IMPERATIVE: Any deforming of the wheel travel sensor supports is forbidden. If there is any deformation found, replace the component.
Cleanliness requirements.
WARNING: Non-respect of the cleanliness requirements may cause a contamination of the circuit and a malfunctioning of the suspension.
Preliminary operations.
The work area must be kept clean and uncluttered.
The technician must wear clean overalls.
Components being stored during the repair must be protected from dust.
The tooling required for an operation on the suspension system should always be cleaned prior to the operation.
During the operation:
- Before operating on the suspension circuit, proceed to clean the hydraulic components and unions.
IMPERATIVE: Approved cleaner: SODIMAC degreaser.
IMPERATIVE: After a dismantling, immediately blank the hydraulic components and unions with plugs. The plugs should be used for one
operation only.
Any component that has been removed must be plugged and placed in a clean plastic bag.
IMPERATIVE: After a dismantling, any cleaning using compressed air or products is strictly prohibited
. Any LDS fluid that is collected must
not be re-used. Any topping-up must be done with new fluid.
