When Driving
i-ACTIVSENSE
NOTE
When the ignition is switched off,
the condition before the system
was turned off is maintained.
For example, if the ignition is
switched OFF while the Blind
Spot Monitoring (BSM) and Rear
Cross Traffi c Alert (RCTA) systems
are operational, the Blind Spot
Monitoring (BSM) and Rear Cross
Traffi c Alert (RCTA) systems remain
operational the next time the ignition
is switched ON.
The Blind Spot Monitoring (BSM)
and Rear Cross Traffi c Alert (RCTA)
systems are turned off when the
battery is disconnected such as
when the battery terminals or fuses
have been removed and re-installed.
To turn the Blind Spot Monitoring
(BSM) and Rear Cross Traffi c Alert
(RCTA) systems back on, press
the Blind Spot Monitoring (BSM)
switch.
