Special features (continued)
Under-inflation detection device.
- Vehicles equipped with the under-inflation detection system are identifiable by the presence of aluminium
valves.
- The under-inflation detection option is possible only on vehicles equipped with aluminium rims.
Composition :
- Four HFtransmitter modules(4)incorporated in the wheels in place of the valves, each including a lithium
battery with 10 yearsguaranteed life.
- AHF receiver incorporated in the communication module under the steering wheel (COM 2000).
- The tightening torque for the nut (5) is 0.6 ± 0.1 m.daN.
WARNING :
- Each time a tyre is replaced, the valve (6) must be replaced.
- Each time a rim is replaced, the seal (7) must be replaced.
- Each time a valve is replaced, it is necessary to have the transmitter recognised by the BSI, with
the aid of a diagnostic tool.

L1
The dimension«L1» for checking front height is between the level of
the front subframe «b» and the wheel axis «a».
This method eliminates all the variations in measurement due to :
Different wheel fiittings.
Vehicle loading.
Wear or incorrect inflation of tyres.
(Measuring from the wheel axis : tool 8006-T)

Rear height Front height
NOTE : After each movement of the vehicle body, and before each mea-
surement :
- Move the vehicle slightly forwards and backwards, by turning the road
wheel by hand.- Check the tyre pressures.
- Release the handbrake.
- Place the manual height control in the «NORMAL» position.
- Engine running.
L2
The dimension«L2»for checking rear height is between the measuring
zone «b» and the wheel axis «a».
H1 = R1 - L1
H1 = Front height(± 6 mm).
R1 =Wheel radius(mm).
L1 = Theoretical dimension between the level of the front subframe and
the wheel axis.H2 = R2 + L2
H2 = Rear height (± 6 mm).
R2 = Wheel radius(mm).
L2 = Theoretical dimension between the measuring zone on the cross-
member support and the wheel axis.

Measuring front height
The measurement of the front dimension «H1» is between ground level
and the measuring zone on the front subframe
(to the rear of the front yokes fixing the suspension arm).
