Brake hold system operating conditions
The brake hold system cannot be turn ed on in the following conditions:●
The back door or hood is not closed. ●
The driver’s door is not closed. ●
The driver is not wearing the seat belt.
If any of the conditions above are detected when the brake hold system is enabled, the
system will turn off and the brake hold standby in dicator light will go of f. In addition, if any
of the conditions are detected while the sy stem is holding the brake, a warning buzzer
will sound and a message will be shown on th e multi-information display. The parking
brake will then be set automatically. ■
Brake hold function ●
If the brake pedal is left released for a period of about 3 minutes after the system has
started holding the brake, the parking brake w ill be set automatically. In this case, a
warning buzzer sounds and a message is shown on the multi-information display.●

NX300h_U_OM78007U This mode employs a radar sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle
following distance, and operates to main tain a suitable following distance from
the vehicle ahead. Note that vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
Example of constant speed cruising
When there are no vehicles ahead The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle dis-
tance can also be set by operating the vehicle-to-vehicle distance control.
Example of deceleration cruising
When a preceding vehicle is driving slower than the set speed appearsWhen 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 system
applies the brakes (the stop lights will come on at this time). A warning tone warns you
when the system cannot decelera te sufficiently to prevent your vehicle from closing in
on the vehicle ahead.
Example of follow-up cruising
When following a preceding vehicle is driving slower than the set speedThe system continues follow-up cruising wh ile adjusting for chan ges in the speed of
the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
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 con-
stant speed cruising.Driving in vehicle-to-vehicle distance control mode

changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle
distance set by the driver. A warning tone warns you when the system cannot deceler-
ate sufficiently to prevent your vehicl e from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your ve hicle will also stop (vehicle is stopped by
system control). After the vehicle ahead starts off, pushing the cruise control lever up
or depressing the accelerator peda l will resume follow-up cruising.

NX300h_U_OM78007U ◆ Lane deviation alert function
When the system judges that the vehicle is deviating from the current traffic lane,
an alert buzzer sounds and it prompts cautions from the display screen of the
multi-information display. When the alert buzzer sounds, please ch eck the surrounding road situation and
return near the center of the white (yello w) lane markers by safely operating the
steering wheel.
◆ Steering control function
If the system judges that the vehicle has de viated from the current traffic lane, it is
displayed in the multi-information displa y and steering force is supplied to the
steering wheel by the steering control, pr oviding required assistance in steering
wheel operation to avoid further deviation from the marker lines. In order to prevent over relying on the system, when the system does not operate the
steering wheel and driving where hands are lightly supporting the steering wheel
continues, a warning message is displa yed on the multi-information display.Functions included with LDA Alert buzzer

Situations in which the pre-collision system does not function properly
The system may not function effectively in situations such as the following:●
On roads with sharp bends or uneven surfaces ●
If a vehicle suddenly moves in front of your vehicle, such as at an intersection ●
If a vehicle suddenly cuts in front of your vehicle, such as when overtaking ●

to a strong impact ●
Due to greatly turning the wheel when an obstacle suddenly appears ahead ■
Automatic cancelation of the pre-collision system
