SYSTEM MAINTENANCE
The TSR system uses the same multi-
sensing front camera unit that is used by
the Lane Departure Warning (LDW) system,
located in front of the interior rearview mir-
ror. For additional information, refer to ”Sys-
tem maintenance” in the “Lane Departure
Warning (LDW)” section.
WARNING
Failure to follow the warnings and in-
structions for proper use of the LDW
system could result in serious injury or
death.
∙ This system is only a warning deviceto inform the driver of a potential un-
intended lane departure. It will not
steer the vehicle or prevent loss of
control. It is the driver’s responsibility
to stay alert, drive safely, keep the ve-
hicle in the traveling lane, and be in
control of the vehicle at all times. The LDW system will operate when the ve-
hicle is driven at speeds of approximately
37 mph (60 km/h) and above, and only
when the lane markings are clearly visible
on the road.
The LDW system monitors the lane mark-
ers on the traveling lane using the camera
unit
Alocated above the inside mirror.
The LDW system warns the driver that the
vehicle is beginning to leave the driving
lane with an indicator and a steering wheel
vibration. For additional information, refer
to “LDW system operation” in this section.
