Tyre pressure control system
The ty re pressure c ontrol system
continuously monitors the pressure in all
four ty res whilst the vehic le is b eing driven.
Ea ch wheel is fitted with a pressure sensor.
Information on indiv id ua l tyre pressures is
sent to a c ontrol unit and the p ressures of
the ty res on the same axle are compared.
If the sy stem detects one or m ore
differences in tyre pressure, the ty res
affected will be show n in the tachometer
display. On vehicles with chec k control 3,
the p ressure in the respective ty re w ill be
accurately shown in the informa tion
display.
For the system to function correctly, all
tyres m ust have been inflated to the
prescribed pressures. The ty re pressure
control sy stem automatically ta kes
account of whether the vehicle is being
driven with tyre pressures for up to
3 occupants or for full load.
O nce the ignition is switched on, the sy stem
is operational and w ill continuously
monitor the tyre pressures at speeds of
approx. 20 m ph (30 km /h) and a bove.

If this lig hts up during a journey, the arrow
will indicate the ty re in which the pressure
has dropped.
If d isplay is yellow
the loss of pressure is minor, continue
driving a t reduced speed. C heck tyre
pressure at next opportunity using suitab le
tyre pressure gauge, and correct the
pressure as required.
If d isplay is red
ma jor d ifference in pressure or complete
loss of pressure! Stop imm ediately and
