WARNING
Always check the surrounding area
visually before making an actual lane
change:
The system is only designed to assist
you in checking for vehicles at your rear
when making a lane change. Due to
certain limitations with the operation
of this system, the BSM warning
indicator light, the warning sound and
the warning screen indicator display
may not activate or they might be
delayed even though a vehicle is in an
adjacent driving lane. Always make it
your responsibility as a driver to check
the rear.

Traffic Sign Recognition System (TSR)*
▼Tra ffi c Sign Recognition System (TSR)
The TSR helps prevent the driver from overlooking traffic signs, and provides support
for safer driving by displaying traffic signs on the active driving display/instrument
cluster which are recognised by the Forward Sensing Camera (FSC) or recorded in
the navigation system while the vehicle is driven.
The TSR displays the speed limit (including auxiliary signs) , do not enter,
traffic stop,
and passing prohibited
* signs.
If the vehicle speed exceeds the speed limit sign indicated in the active driving
display/instrument cluster while the vehicle is driven, the system notifies the driver
using the indication in the active driving display/instrument cluster and a warning
sound.
