When Driving

Blind Spot Monitoring (BSM) System

Blind Spot Monitoring (BSM) System
The Blind Spot Monitoring (BSM) system is designed to assist the driver by monitoring
blind spots on both sides of the vehicle to the rear in certain situations such as when
changing lanes on roads and freeways or reversing the vehicle from a parking garage.
The Blind Spot Monitoring (BSM) System consists of the Blind Spot Monitoring (BSM)
and Rear Cross Traffi c Alert (RCTA).
WARNING
Do not rely completely on the Blind Spot Monitoring (BSM) system. Always look over
your shoulder before changing lanes or reversing the vehicle from a parking garage:
The Blind Spot Monitoring (BSM) system can assist the driver in confi rming the safety of
the surroundings but is not a complete substitute. The driver is responsible for assuring
lane changes and other maneuvers. Always pay attention to the direction in which the
vehicle is traveling and the vehicle's surroundings.
NOTE
The detectability of the radar sensors has its limitations. The Blind Spot Monitoring
(BSM) System may not operate properly under the following conditions:
Ice, snow, or soil adheres to the rear bumper surface around the radar sensors.
During adverse weather conditions such as rain or snow, or under conditions where
water is sprayed.
The rear bumper area around the radar sensors is blocked by foreign material (such as
stickers or a bicycle carrier).
The radar sensors do not detect human, animal, shopping cart, bicycle, or static objects
such as fences.
The radar sensors may not detect all types of vehicles around your vehicle, especially the
following types of vehicles:
Motorcycles
Vehicles with body shapes that radar may not refl ect such as a fl atbed trailer with no
cargo.
Vehicles with lower body height such as sports cars.
Although the system may detect objects on the road side such as parked vehicles or
guardrails and operate the warning light/beep, it does not indicate a malfunction.
If the vehicle is driven on a road with less traffi c and few vehicles that the radar sensors
can detect, the system may pause (the Blind Spot Monitoring (BSM) OFF indicator light
in the instrument cluster fl ashes). However, it does not indicate a malfunction.
