234 Car care and technical information
Automatic tire pressure
monitoring system
The system consists of a sensor in each
wheel and a receiver. The sensors are
located inside the tire in direct connection
with the air pressure valves.
Make sure that wheels with sensors for tire
pressure monitoring are fitted during
replacement if the car has automatic tire
pressure monitoring.
Tire pressure information is transmitted
wirelessly to the receiver.
The system checks the tire pressures when
speed exceeds 19 mph (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.
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 tire pres-
sure is too high.
WARNING
The system is an aid to the driver. The
driver always has the responsibility that
the tires have the correct air pressure.
For optimum safety, economy and com-
fort tire pressures should be checked reg-
ularly even if the automatic tire pressure
monitoring has not alarmed.
NOTE
Tire 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 tire opposite the
valve.
• During removal the tire machine must
not come closer than ±10° from the
valve.
• During fitting, start 20° after the valve
and finish 20° before the valve.
• Do not inflate the tire with pressure
higher than 102 psi (700 kPa).
