Tire Pressure Monitoring System
Tire Pressure Monitoring System
Initialization
In the following cases, system
initialization must be performed so that the
system operates normally.
A tire pressure is adjusted.
      
Tire rotation is performed.
      
A tire or wheel is replaced.
      
The battery is replaced or completely
      
drained.
The tire pressure monitoring system
      
warning light is illuminated.
Initialization method
1. Park the car in a safe place and fi rmly
apply the parking brake.
2. Let the tires cool, then adjust the tire
pressure of all four (4) tires to the
specifi ed pressure indicated on the tire
pressure label located on the driver's
door frame (door open).
Refer to Tires on page 9-10 .
3. Switch the ignition ON.
4. Press and hold the tire pressure
monitoring system set switch and
verify that the tire pressure monitoring
system warning light in the instrument
cluster fl ashes twice and a beep sound
is heard once.

CAUTION
If the system initialization is performed
without adjusting the tire pressure,
the system cannot detect the normal
tire pressure and it may not illuminate
the tire pressure monitoring system
warning light even if a tire pressure is
low, or it may illuminate the light even
if the pressures are normal.
Adjust the tire pressure on all four
tires and initialize the system when
the warning light is turned on. If the
warning light turns on for a reason
other than a fl at tire, the tire pressure
of all four tires may have decreased
naturally.
The system initialization will not be
performed if the switch is pressed while
the vehicle is being driven.
