apply the parking brake.
2. Let the tyres cool, then adjust the tyre
pressure of all four (4) tyres to the

Tyre Pressure Monitoring System
If the system initialization is performed
without adjusting the tyre pressure, the
system cannot detect the normal tyre
pressure and it may not illuminate the
tyre pressure monitoring system warning
light even if a tyre pressure is low, or
it may illuminate the light even if the
pressures are normal.
The system initialization will not be
performed if the switch is pressed while
the vehicle is being driven.
