WARNING: «Check and adjust the axle geometries at referenceheight».
Conditions for checking and adjusting.
Check the tyre pressures.
Place the vehicle on a 4 column lift.
Check and adjust if necessary the vehicle heights (see corresponding
operation).
Steering rack locked at its zero point (see corresponding operation).
Switch off the ignition before removing the tools from the wheels.
Lower the vehicle.
Start the engine.
Put the vehicle in the high position.
Put the vehicle in the normal height position (driving height).
Stop the engine.
Switch on the ignition.
Check and adjust the front and rear axle geometries at reference
height.
WARNING: Do not switch off the ignition during checking and
adusting of the front and rear axle geometries.
NOTE:Front of vehicle (following the arrow).

Bleeding.
Connect tool [2]or [3]to the vehicle's diagnostic socket.
Switch on the ignition.
Perform a global test.
Go into the menu:
- Variable damping.
- Bleeding the suspension circuit.
Follow the instructions on the screen.
Apply a pressure of 0.5 barin the LDSfluid reservoir (using a tool FACOM 920).
Start the engine.
Wait for the vehicle height to stabilise.
Place the vehicle in the high position.
Place the vehicle in the low position.
Move the steering in each direction, from lock to lock.
Stop the engine.
Check the LDSfluid level.

Checking and topping up the LDS fluid level.
NOTE:Checking the LDSfluid level is done with the vehicle in the forced low position
(hydraulic suspension circuit depressurised).
"a"Maximum level for the LDSfluid
"b"Minimum level for the LDSfluid
Open the cap (3).
If necessary, add LDSfluid up to the maximum level "a".
IMPERATIVE: A container of LDS that has been opened must be sealed and kept in a
clean place. A container of LDS has to be used up within two weeks of opening, after
which any unused LDS fluid must be disposed of.
