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).

Composition of the Built-in Hydro-electronic Interface:
- An electric motor.
- A pump with 5 pistons.
- 4electrovalves.
- 2non-return valves.
- A pressure limiter.
- An anti-pulse accumulator.
- A filter.
- The suspension ECU.
Features of variable damping suspension.
Variable damping suspension ECU (CSS).
The ECU (CSS)is located in the engine compartment, in the ECU tray.
The ECU (CSS)manages the different damping laws, as a function of the information delivered
by the following components:
- The 4wheel travel sensors.
- The 2suspension pressure sensors.
- The speed of the vehicle.
- The speed of rotation of the steering wheel.
The suspension ECU (CSS)pilots the following components:
- The 4variable damping suspension actuators.
- The Built-in Hydro-electronic Interface (BHI).
