Instances of the BSM function 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 a bicycle carrier or other accessory is installed to the rear of the vehicle
• When towing a trailer

The RCTA function uses radar sensors to detect vehicles approaching
from the right or left at the rear of the vehicle and alerts the driver of
the presence of such vehicles by fl ashing the outside rear view mirror
indicators and sounding a buzzer.

WARNING
■ Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The RCTA function is only a supplementary function which alerts the driver
that a vehicle is approaching from the right or left at the rear of the vehicle.
As the RCTA function may not function correctly under certain conditions,
the driver’s own visual confirmation of safety is necessary. Over reliance on
this function may lead to an accident resulting death or serious injury.

The areas that vehicles can be detected in are outlined below.
The buzzer can alert the driver of faster vehicles approaching from
farther away.
Example:
■ The RCTA function is operational when
The RCTA function operates when all of the following conditions are met:
● The RCTA function is on.
● The shift lever is in R.
● The vehicle speed is less than approximately 5 mph (8 km/h).
● The approaching vehicle speed is between approximately 5 mph (8 km/h)
and 18 mph (28 km/h).

Conditions under which the RCTA fu nction will not detect a vehicle
The RCTA 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 RCTA function may not function correctly
●The RCTA function may not detect vehicles correctly in the following situa-
tions:
• 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
• When towing a trailer
●
Vehicles that the sensors cannot detect
due to obstructions

Instances of the RCTA 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

◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Enhanced VSC (Enhanced Ve hicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery
road surfaces by controllin g steering performance.
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure for individual wheels and reducing driving torque when
trailer sway is detected.
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
Driving assist systems
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.
