●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display, airport or other facility that generates strong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication device
If tire position information is not correctly displayed due to the radio wave conditions, the display may be corrected by driving and changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off could be extended.
●When tire inflation pressure
declines rapidly for example when a tire has burst, the warning may not function.
Installing tire pressure warning valves and transmitters( Vehicles with tire pressure warning system)
When replacing tires or wheels, tire pressure warning valves and transmitters must also be installed.
When new tire pressure warning valves and transmitters are installed, new ID codes must be registered in the tire pressure warning computer and the tire pressure warning system must be initialized.( �P. 579)
■ When replacing the tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered, the tire pressure warning system will not work properly. After driving for about 10 minutes, the tire pressure warning light blinks for 1
minute and stays on to indicate a system malfunction.

wheels, tire pressure warning valves, transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters, contact your SUBARU dealer as the tire pressure warning valves and transmitters may be damaged if not handled correctly.
●Make sure to install the tire valve caps. If the tire valve caps are not installed, water could enter the tire pressure warning valves and the tire pressure warning valves could be bound.

than those specified. The cap may become stuck.
■ To avoid damage to the tire pressure warning valves and
transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact your SUB- ARU dealer as soon as possible.
