Driving
WARNING
●Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range has limited capabil-
ity to prevent or avoid a collision with a vehicle traveling ahead. Therefore,
if there is ever any danger, the driver must take immediate and direct con-
trol of the vehicle and act appropriately in order to ensure the safety of all
involved.
■Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.
●Roads where there are pedestrians, cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those covered with rain, ice or snow
●On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
●At entrances to freeways and highways
●When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
●When there is rain, snow, etc. on the front surface of the radar sensor or
camera sensor
●In traffic conditions that require frequent repeated acceleration and decel-
eration
●When an approach warning buzzer is heard often

2664-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehicles
up to approximately 328 ft. (100 m) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on down-
hill 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 distance can also be set by operating the vehicle-to-vehicle dis-
tance switch.
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 suffi-
ciently 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 will resume follow-up
cruising.

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.
Press the cruise control main
switch to activate the cruise
control.
Dynamic radar cruise control indi-
cator will come on and a message
will be displayed on the multi-infor-
mation display.
Press the switch again to deacti-
vate the cruise control.
If the cruise control main switch is pressed and held for 1.5 seconds or
more, the system turns on in constant speed control mode. (P. 272)
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 30 mph
[50 km/h]) and press the “- SET”
switch to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the switch is released becomes the
set speed.
If the switch is operated while the vehicle speed is below approximately 30
mph (50 km/h) and a preceding vehicle is present, the set speed will be
adjusted to approximately 30 mph (50 km/h).

2684-5. Using the driving support systems
To change the set speed, operate the “+ RES” or “- SET” switch until
the desired set speed is displayed.
Increases the speed
(Except when the vehicle has been
stopped by system control in vehi-
cle-to-vehicle distance control
mode)
Decreases the speed
Fine adjustment: Press the switch.
Large adjustment: Press and hold
the switch to change the speed,
and release when the desired
speed is reached.
In the vehicle-to-vehicle distance control mode, the set speed will be
increased or decreased as follows:
For U.S. mainland and Hawaii
Fine adjustment: By 1 mph (1.6 km/h)
*1 or 1 km/h (0.6 mph)*2 each time
the switch is pressed
Large adjustment: Increases or decreases in 1 mph (1.6 km/h)
*1 or 1 km/h
(0.6 mph)
*2 increments for as long as the switch is held
For Puerto Rico
Fine adjustment: By 1 mph (1.6 km/h)
*1 or 1 km/h (0.6mph)*2 each time
the switch is pressed
Large adjustment: Increases or decreases in 5 mph (8 km/h)
*1 or 5 km/h
(3.1 mph)
*2 increments for as long as the switch is held
In the constant speed control mode (P. 272), the set speed will be
increased or decreased as follows:
Fine adjustment: By 1 mph (1.6 km/h)*1 or 1 km/h (0.6 mph)*2 each time
the switch is pressed
Large adjustment: The speed will continue to change while the switch is
held.
*1: When the set speed is shown in “MPH”
*2: When the set speed is shown in “km/h”

Pressing the switch changes the
vehicle-to-vehicle distance as fol-
lows:
Long

The vehicle-to-vehicle distance is
set automatically to long mode
when the power switch is turned to
ON mode.
If a vehicle is running ahead of you, the preceding vehicle mark will also be
displayed.
Select a distance from the table below. Note that the distances shown
correspond to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle
distance increases/decreases in accordance with vehicle speed.
When the vehicle is stopped by system control, the vehicle stops at a
certain vehicle-to-vehicle distance depending on the situation.

2704-5. Using the driving support systems
After the vehicle ahead of you
starts off, press the “+ RES”
switch.
Your vehicle will also resume fol-
low-up cruising if the accelerator
pedal is depressed after the vehi-
cle ahead of you starts off.
Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is
depressed.
(When the vehicle has been
stopped by system control,
depressing the brake pedal does
not cancel the setting.)
Pressing the “+ RES” switch resumes the cruise control and returns
vehicle speed to the set speed.
However, when a vehicle ahead is not detected, cruise control does not
resume when the vehicle speed is approximately 25 mph (40 km/h) or less.

Driving
When your vehicle is too close to
a vehicle ahead, and sufficient
automatic deceleration via the
cruise control is not possible, the
display will flash and the buzzer
will sound to alert the driver. An
example of this would be if
another driver cuts in front of you
while you are following a vehicle.
Depress the brake pedal to
ensure an appropriate vehicle-to-
vehicle distance.
■Warnings may not occur when
In the following instances, warnings may not occur even when the
vehicle-to-vehicle distance is small.
●When the speed of the preceding vehicle matches or exceeds
your vehicle speed
●When the preceding vehicle is traveling at an extremely slow
speed
●Immediately after the cruise control speed was set
●When depressing the accelerator pedal

2724-5. Using the driving support systems
When constant speed control mode is selected, your vehicle will main-
tain a set speed without controlling the vehicle-to-vehicle distance.
Select this mode only when vehicle-to-vehicle distance control mode
does not function correctly due to a dirty radar sensor, etc.
With the cruise control off,
press and hold the cruise con-
trol main switch for 1.5 seconds
or more.
Immediately after the switch is
pressed, the radar cruise control
indicator will come on. Afterwards,
it switches to the cruise control
indicator.
Switching to constant speed control mode is only possible when operating
the switch with the cruise control off.
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 25 mph
[40 km/h]) and press the “- SET”
switch to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the switch is released becomes the
set speed.
