Driving
The areas that vehicles can be detected in are outlined below.
To give the driver a more consistent time to react, the buzzer can alert
for faster vehicles from farther away.
Example:
■ The Rear Cross Traffic Alert function is operational when
● The BSM system is set to on. ( →P. 139)
● The shift position is in R.
● Vehicle speed is less than approximately 5 mph (8 km/h).
● Approaching vehicle speed is between approximately 5 mph (8 km/h) and
18 mph (28 km/h).

■Conditions under which the Rear Cr oss Traffic Alert function will not
detect a vehicle
The Rear Cross Traffic Alert function is not designed to detect the following
types of vehicles and/or objects:
● Vehicles approaching from directly behind
● Vehicles backing up in a parking space next to your vehicle
● Guardrails, walls, signs, parked vehi cles and similar stationary objects
*
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
● Vehicles approaching from the parking spaces next to your vehicle
*
*
: Depending on the conditions, detection of a vehicle and/or object may
occur.
■ Conditions under which the Rear Cr oss Traffic Alert function may not
function correctly
● The Rear Cross Traffic Alert function 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 surround- ing 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 a vehicle is approaching at high speed
●
Vehicles that the sensors cannot detect
due to obstructions

• Immediately after the Blind Spot Monitor main switch is turned on
• Immediately after the hybrid system is started with the Blind Spot Monitor
main switch on
• When backing up on a slope with a
sharp change in grade
• When backing out of a shallow angle parking spot
• When the sensors cannot detect a vehicle due to obstructions

●Instances of the Rear Cross Traffic Alert function unnecessarily detecting a
vehicle and/or object may increase in the following situations:
• When a vehicle passes by the side of your vehicle
• When the distance between your vehicle and metal objects, such as a
guardrail, wall, sign, or parked vehicle, which may reflect electrical waves
toward the rear of the vehicle, is short
• When the parking space faces a
street and vehicles are being driven
on the street

The Intuitive parking assist can be enabled/disabled on screen
( → P. 139) of the multi-information display.
When ON is selected, Intuitive
parking assist indicator will come
on.
Once OFF is selected, the Intuitive parking assist will not return to ON until
it is turned to ON by the screen of multi-information display again.
(The system does not automatically return to ON even when the hybrid
system is restarted.)
∗: If equipped
The distance from your vehicle to nearby obstacles when paral-
lel parking or maneuvering into a garage is measured by the
sensors and communicated via the displays and a buzzer.
Always check the surrounding area when using this system.

When an obstacle is dete cted, the buzzer sounds.
● As the obstacle is approached, th e buzzer sounds more rapidly.
When the obstacle is extremely close, the buzzer switches from
sounding intermittently (short beeps ) to continuously (a long beep).
• Distance to obstacle detected by front corner sensor is approxi- mately 1.2 ft. (35 cm) or less
• Distance to obstacle detected by front side sensor or rear side
sensor is approximately 1.0 ft. (30 cm) or less
• Distance to obstacle detected by front sensor is approximately
1.2ft. (35cm) or less
• Distance to obstacle detected by rear corner sensor is approxi- mately 1.2 ft. (35 cm) or less
• Distance to obstacle detected by back sensor is approximately
1.2ft. (35cm) or less
● When an obstacle is detected by multiple sensors simultaneously,
the buzzer sounds according to th e distance to the closest obsta-
cle.
● When obstacles are simultaneously detected to the front and rear
of the vehicle, separ ate buzzers sound patterns according to the
distance to each obstacle.
The volume and timing of the buzzer can be changed. ( →P. 748)
