Toyota CH-R: Blind Spot Monitor operation
■ Objects that can be detected while driving
The Blind Spot Monitor uses rear side radar sensors to detect the following
vehicles traveling in adjacent lanes and advises the driver of the presence
of such vehicles via the indicators on the outside rear view mirrors.

- Vehicles that are traveling in areas that are not visible using the
outside
rear view mirrors (the blind spots)
- Vehicles that are approaching rapidly from behind in areas that are not
visible using the outside rear view mirrors (the blind spots)
■ Detection range while driving
The areas that vehicles can be detected in are outlined below.

The range of each detection area is:
- Approximately 0.5 m (1.6 ft.) to 3.5 m (11.5 ft.) from either side of
the
vehicle*1
- Approximately 1 m (3.3 ft.) forward of the rear bumper*2
- Approximately 3 m (9.8 ft.) from the rear bumper
- Approximately 3 m (9.8 ft.) to 70 m (230 ft.) from the rear bumper*3
*1: The area between the side of the vehicle and 0.5 m (1.6 ft.) from the
side of the
vehicle cannot be detected.
*2: While the vehicle is to being overtaken, up to approximately 3 m (9.8 ft.)
forward
of the rear bumper will be detected.
*3: The greater the difference in speed between your vehicle and the detected
vehicle
is, the farther away the vehicle will be detected, causing the outside rear view
mirror indicator to illuminate or flash.
■ The Blind Spot Monitor linked function
The LDA (Lane Departure Alert) has a function that uses information of
detected vehicles driving in an adjacent lane. For details about the function
and its operating conditions.
■The Blind Spot Monitor is operational
when
The Blind Spot Monitor is operational
when all of the following conditions are
met:
- The power switch is in ON.
- The Blind Spot Monitor is on.
- The shift position is in a position other
than R.
- The vehicle speed is approximately 10
km/h (7 mph) or more.
■The Blind Spot Monitor will detect a
vehicle when
The Blind Spot Monitor will detect a
vehicle present in the detection area in
the following situations:
- A vehicle in an adjacent lane overtakes
your vehicle.
- You overtake a vehicle in an adjacent
lane slowly.
- Another vehicle enters the detection
area when it changes lanes.
■Situations in which the Blind Spot
Monitor cannot detect vehicles
The Blind Spot Monitor cannot detect
the following vehicles and other objects:
- Small motorcycles, bicycles, pedestrians,
etc.,*
- Vehicles traveling in the opposite
direction
- Guardrails, walls, signs, parked vehicles
and similar stationary objects*
- Following vehicles that are in the
same lane*
- Vehicles traveling 2 lanes away from
your vehicle*
- Vehicles which are being overtaken
rapidly by your vehicle*
*: Depending on the conditions, detection
of a vehicle and/or object may
occur.
■Conditions in which a buzzer may
not sound
In situations such as the following, while
the turn signal lever is being operated,
the indicator will flash but a buzzer may
not sound.
- When a second vehicle is detected
while the turn signal lever is being
held
- When overtaking a vehicle in the adjacent
lane at a much higher speed than
it*
*: Depending on the situations, a buzzer
may sound.
■Conditions under which the system
may not function correctly
- The Blind Spot Monitor may not detect
vehicles correctly in the following situations:
- When the sensor is misaligned due to
a strong impact to the sensor or its
surrounding area
- When mud, snow, ice, a sticker, etc.,
is covering the sensor or surrounding
area on the rear bumper
- When driving on a road surface that is
wet with standing water during bad
weather, such as heavy rain, snow, or
fog
- When multiple vehicles are approaching
with only a small gap between
each vehicle
- When the distance between your vehicle
and a following vehicle is short
- When there is a significant difference
in speed between your vehicle and
the vehicle that enters the detection
area
- When the difference in speed
between your vehicle and another
vehicle is changing
- When a vehicle enters a detection
area traveling at about the same
speed as your vehicle
- As your vehicle starts from a stop, a
vehicle remains in the detection area
- When driving up and down consecutive
steep inclines, such as hills, dips
in the road, etc.
- When driving on roads with sharp bends, consecutive curves, or
uneven
surfaces
- When vehicle lanes are wide, or when
driving on the edge of a lane, and the
vehicle in an adjacent lane is far away
from your vehicle
- When an accessory (such as a bicycle
carrier) is installed to the rear of the
vehicle
- When there is a significant difference
in height between your vehicle and
the vehicle that enters the detection
area
- Immediately after the Blind Spot Monitor
is turned on
- When towing with the vehicle
- Instances of the Blind Spot Monitor
unnecessarily detecting a vehicle
and/or object may increase in the following
situations:
- When the sensor is misaligned due to
a strong impact to the sensor or its
surrounding area
- When the distance between your vehicle
and a guardrail, wall, etc., that
enters the detection area is short
- When driving up and down consecutive
steep inclines, such as hills, dips
in the road, etc.
- When vehicle lanes are narrow, or
when driving on the edge of a lane,
and a vehicle traveling in a lane other
than the adjacent lanes enters the
detection area
- When driving on roads with sharp
bends, consecutive curves, or uneven
surfaces
- When the tires are slipping or spinning
- When the distance between your vehicle
and a following vehicle is short
- When an accessory (such as a bicycle
carrier) is installed to the rear of the
vehicle
- When towing with the vehicle
