tance, and operates to maintain a suitable following distance from the vehicle 
ahead. The desired vehicle-to-vehicle distance can also be set by operating the 
vehicle-to-vehicle distance switch.

When driving on downhill slopes, the vehicle-to-vehicle distance may become shorter.

Example of constant speed cruising
When there are no vehicles ahead

The vehicle travels at the speed set by the driver.

Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears

When a vehicle is detected running ahead of you, the system automatically decelerates 
your vehicle. When a greater reduction in vehicle speed is necessary, the system applies 
the brakes (the stop lights will come on at this time). The system will respond to changes in 
the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by 
the driver. Approach warning warns you when the system cannot decelerate sufficiently to 
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pressing the “+RES” switch or depressing 
the accelerator pedal (start-off operation) will resume follow-up cruising. If the start-off 
operation is not performed, system control continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an overtaking lane while 
driving at 50 mph (80 km/h) or more, the vehicle will accelerate to help to overtake a 
passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely based on 
the location of the steering wheel in the vehicle (left side driver position versus right side 
driver position.) If the vehicle is driven to a region where the overtaking lane is on a different 
side from where the vehicle is normally driven, the vehicle may accelerate when the turn 
signal lever is operated in the opposite direction to the overtaking lane (e.g., if the driver 
normally operates the vehicle in a region where the overtaking lane is to the right but then

the right turn signal is activated).

Example of acceleration
When there are no longer any preceding vehicles driving slower than the set 
speed

The system accelerates until the set speed is reached. The system then returns to constant 
speed cruising.

BSM (Blind Spot Monitor)

The Blind Spot Monitor is a system 
that uses rear side radar sensors 
installed on the inner side of the 
rear bumper on the left and right 
side to assist the driver in confirm-
ing safety when changing lanes.

WARNING

■

Cautions regarding the use of the sys-

tem

The driver is solely responsible for safe 

driving. Always drive safely, taking care 

to observe your surroundings.
The Blind Spot Monitor is a supplemen-

tary function which alerts the driver that a 

vehicle is in a blind spot of the outside 

rear view mirrors or is approaching rap-

idly from behind into a blind spot. Do not 

overly rely on the Blind Spot Monitor. As 

the function cannot judge if it is safe to 

change lanes, over reliance could lead to 

an accident resulting in death or serious 

injury.
As the system may not function correctly 

under certain conditions, the driver’s own 

visual confirmation of safety is necessary.

detect the following types of vehicles and/or 

objects:

●

Small motorcycles, bicycles, pedestrians, 
etc.

*

●

Vehicles traveling in the opposite direc-

tion

●

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 rap-
idly by your vehicle

*

*

: Depending on the conditions, detection 

of a vehicle and/or object may occur.

■

Conditions under which the system may 

not function correctly

●

The Blind Spot Monitor 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 sur-

rounding 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 vehi-

cle

• 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 vehi-

cle 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 vehi-

cle 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 vehi-

cle

• 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

●

Instances of the Blind Spot Monitor 

unnecessarily detecting a vehicle and/or 

object may increase in the following situ-

• 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 vehi-

cle traveling in a lane other than the adja-

cent 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 vehi-

PKSA (Parking Support 
Alert)

The Parking Support Alert system 
consists of the following functions 
that operate when driving at a low 
speed or backing up, such as when 
parking. When the system deter-
mines that a collision with a 
detected object, such as a wall, or 
pedestrian is high, a warning oper-
ates to urge the driver to take eva-
sive action.
