■Hands off steering wheel warning
In the following situations, a warning
message urging the driver to hold the steering wheel and the symbol shown in the illustration are displayed on the
multi-information display to warn the driver. The warning stops when the sys-tem determines that the driver holds the
steering wheel. Always keep your hands on the steering wheel when using this system, regardless of warnings.

driver is driving without holding the steering wheel while the system is operating
If the driver continues to keep their
hands off of the steering wheel, the
buzzer sounds, the driver is warned and
the function is temporarily canceled.
This warning also operates in the same
way when the driver continuously oper-
ates the steering wheel only a small
amount.
●When the system determines that the vehicle may deviate from the lane
while driving around a curve while the lane centering function is operating.
Depending on the vehicle condition and
road conditions, the warning may not
operate. Also, if the system determines
that the vehicle is driving around a
curve, warnings will occur earlier than
during straight-lane driving.
●When the system determines that the driver is driving without holding the steering wheel while the steering
wheel assist of the steering assist function is operating.
If the driver continues to keep their
hands off of the steering wheel and the
steering wheel assist is operating, the
buzzer sounds and the driver is warned.
Each time the buzzer sounds, the con-
tinuing time of the buzzer becomes lon-
ger.

●“LTA Unavailable”
The system is temporarily canceled due
to a malfunction in a sensor other than
the front camera. Turn the LTA system
off, wait for a little while, and then turn
the LTA system back on.
●“LTA Unavailable at Current Speed”
The function cannot be used as the
vehicle speed exceeds the LTA opera-
tion range. Drive slower.
■Customization
Function settings can be changed. (Cus- tomizable features: P.359)
*: If equipped
In vehicle-to-vehicle distance con-
trol mode, the vehicle automati-
cally accelerates and decelerates
to match the speed changes of the
preceding vehicle even if the accel-
erator pedal is not depressed. In
constant speed control mode, the
vehicle runs at a fixed speed.
Use the dynamic radar cruise con-
trol on freeways and highways.

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 no rmally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e 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 syst em then returns to
constant speed cruising.
1 Press the cruise control main
switch to activate the cruise con-
trol.
Dynamic radar cruise control indicator will come on and a message will be dis-
played on the multi-information display. Press the switch again to deactivate 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.186)

2 Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 30 km/h
[20 mph]) 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.

decreases in 5 km/h (3.1 mph)*1 or 5
mph (8 km/h)*2 increments for as long
as the switch is held
In the constant speed control mode
( P.186), the set speed will be
increased or decreased as follows:
Fine adjustment: By 1 km/h (0.6 mph)*1
or 1 mph (1.6 km/h)*2 each time the
switch is pressed
Large adjustment: The speed will con-
tinue to change while the switch is held.

speed of 80 km/h (50 mph). Vehi-
cle-to-vehicle distance
increases/decreases in accor-
dance with vehicle speed.
1 Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is depressed.
2 Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed.
However, cruise control does not
resume when the vehicle speed is
approximately 25 km/h (16 mph) or
less.
When your vehicle is too close to a
vehicle ahead, and sufficient auto-
matic 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 follow-
ing 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 vehi-
cle-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 con-
trol speed was set
 When depressing the accelerator
