Automatic tyre pressure
monitoring 3
WARNING
The system is an aid to the driver. The
driver always has the responsibility that
the tyres have the correct air pressure.
Never use the system to assist with tyre
pressure reading when adjusting tyre
pressures.
Wear indicator
For optimum safety, economy and com-
fort tyre pressures should be checked reg-
ularly even if the automatic tyre pressure
monitoring has not alarmed.
The system consists of a sensor in each
wheel and a common receiver. The sensors
are located inside the tyre in direct connec-
tion with the air pressure valves.
Make sure that wheels with sensors for tyre
pressure monitoring are fitted during
replacement if the car has automatic tyre
pressure monitoring.
NOTICE
Tyre replacement must take place with
great care to avoid damaging the sensors
that are built together with the valves.
• Remove the rear side first.
• Start to remove the tyre opposite the
valve.
• During removal the tyre machine must
not come closer than ±10° from the
valve.
• During fitting, start 20° after the valve
and finish at the latest 20° before the
valve.
• Do not inflate the tyre with pressure
higher than 7 bar (102 psi).
Tyre pressure information is transmitted
wireless to the receiver.
The system checks the tyre pressures when
speed exceeds 30 km/h.
The system is self-programming which
means that the wheels can be shifted
around without any need for adjustment.
The spare wheel has no sensor.
Car care
Valve with sensor
The sensor batteries last for 10 years or
around 160 000 km. The battery cannot be
replaced. The whole sensor must be
replaced.
The system does not warn if the tyre pres-
sure is too high.
If the system has warned or triggered an
alarm due to inadequate pressure then
the pressure must be reset to the recom-
mended pressure so that the warning/alarm
is cleared.
