5-5. Using the driving support systems
Driving
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle fol-
lowing distance, 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
WARNING
OWhen there is rain, snow, etc. on the front surface of the radar or
front camera
OIn traffic conditions that require fre-
quent repeated acceleration and deceleration
OWhen your vehicle is towing a trailer or during emergency towing
OWhen an approach warning buzzer is heard often

3365-5. Using the driving support systems
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem 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 vehi-
cle-to-vehicle distance set by the driver. Approach warning warns you when the sys-
tem 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 system 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 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take 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 over-
taking lane is on a different side from where the vehicle is normally driven, the vehi-
cle 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 drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
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.
