Conditions under which the BSM func tion may not function correctly●
The BSM 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 surround-
ing 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 wi th 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 in clines, 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 drivin g on the edge of a lane, and the vehicle
in an adjacent lane is far away from your vehicle
• When a bicycle carrier or other accessory 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 BSM function is turned on ●
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 surround-
ing 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 in clines, 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 ad jacent 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

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

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 fu nction which alerts the driver that a vehi-
cle 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 confirma-
tion of safety is necessary. Over reliance on this function may lead to an accident
resulting death or serious injury.

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

Driving
Driving assist systems ◆ Multi Terrain 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 su rface, or in off-road conditions (such as
rough roads, sand and mud)
◆ Brake assist Generates an increased leve l 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
◆ Active TRAC (Traction Control) Helps to maintain drive power and prevent the 4 wheels from spinning when starting
the vehicle or accelerating on slippery roads, or in off-road conditions
◆ Hill-start assist control Helps to reduce the backward movement of the vehicle when starting on an incline or
slippery slope
◆ AVS (Adaptive Variable Suspension system) By independently controlling the damping force of the shock absorbers for each of
the 4 wheels according to the road and dr iving conditions, this system helps riding
comfort with superior stee ring stability, and helps good vehicle posture. When
SPORT S+ mode is selected by the drivin g mode select switches, the damping force
is suitable for sporty driving. (  P. 2 8 6 )
◆ VGRS (Variable Gear Ratio Steering) Helps to adjust the wheel turning angle in accordance with the vehicle speed and
steering wheel movement.
◆ Trailer Sway Control Helps the driver to control trailer sway by selectively applying brake pressure for indi-
vidual wheels and reducing engine to rque when trailer sway is detected.
Trailer Sway Control is part of the VSC system and will not operate if VSC turned off
or experiences a malfunction.To help enhance driving safety and performance, the following systems oper-
ate automatically in response to various driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too
heavily when operating the vehicle.
