nated or flashing ( P.77, 79) and all
of the following co nditions are met:
●Engine output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is 9 mph (15
km/h) or less.
• Vehicles are approaching from the right or left at the rear of the vehi-
cle at a traveling speed of less
than approximately 5 mph (8

The function will stop operating if
any of the following conditions are
met:
●Engine output restriction control
• The Parking Support Brake is dis- abled.
• The collision becomes avoidable
with normal brake operation.
• A vehicle is no longer approaching from the right or le ft at the rear of

RCTA function detects a vehicle and
provides an alert, the Parking Sup-
port Brake function (rear-crossing
vehicles) may not start operating.
