on the lights as follows:
1 The headlights, daytime
running lights ( →P.144) and all
the lights listed below turn on
and off automatically.
2 The front position, tail,
license plate and instrument
panel lights turn on.
3 The headlights and all the
lights listed above turn on.
■AUTO mode can be used when
The engine switch is in ON.
■Daytime running light system
To make your vehicle more visible to
other drivers during daytime driving, the
daytime running lights turn on automati-
cally whenever the engine is started and
the parking brake is released with the
headlight switch in the position.
(Illuminate brighter than the front posi-
tion lights.) Daytime running lights are
not designed for use at night.
■Headlight control sensor
The sensor may not function properly if
an object is placed on the sensor, or anything that blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting the level of ambient light and may cause the automatic headlight sys-
tem to malfunction.
■Automatic light off system
●When the light switch is in or
: The headlights and front fog
lights turn off automatically if the
engine switch is turned to ACC or
OFF.
●When the light switch is in : The
headlights and all lights turn off auto-
matically if the engine switch is turned
to ACC or OFF.
To turn the lights on again, turn the
engine switch to ON, or turn the light

4-5. Using the driving support systems
*: If equipped
The system can detect the following (The detectable objects differs
depending on the function.):
PCS (Pre-Collision System)*
The pre-collision system uses a radar sensor and front camera to
detect objects (→P.160) in front of the vehicle. When the system
determines that the possibility of a frontal collision with an object is
high, a warning operates to urge the driver to take evasive action
and the potential brake pressure is increased to help the driver
avoid the collision. If the system determines that the possibility of a
frontal collision with an object is extremely high, the brakes are
automatically applied to help avoid the collision or help reduce the
impact of the collision.
The pre-collision system can be disabled/enabled and the warning
timing can be changed. (→P.164)

■Enabling/disabling the pre-col-
lision system
The pre-collision system can be
enabled/disabled on ( →P.361)
of the multi-information display.
The system is automatically enabled
each time the engine switch is turned to
ON.
If the system is disabled, the PCS
warning light will turn on and a
message will be displayed on the
multi-information display.
WARNING
• In some situations, while the emer- gency steering assist is operating,
operation of the function may be canceled if the accelerator pedal is depressed strongly, the steering
wheel is operated sharply or the brake pedal is being depressed and the system determines that the
driver is taking evasive action.
• When the emergency steering
assist is operating, if the steering wheel is held firmly or is operated in the opposite direction to that which
the system is generating torque, the function may be canceled.
■When to disable the pre-colli-sion system
In the following situations, disable the
system, as it may not operate prop- erly, possibly leading to an accident resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another vehicle
●When transporting the vehicle via truck, boat, train or similar means of transportation
●When the vehicle is raised on a lift with the engine running and the
tires are allowed to rotate freely
●When inspecting the vehicle using
a drum tester such as a chassis dynamometer or speedometer tes-ter, or when using an on vehicle
wheel balancer
●When a strong impact is applied to
the front bumper or front grille, due to an accident or other reasons
●If the vehicle cannot be driven in a stable manner, such as when the vehicle has been in an accident or
is malfunctioning
●When the vehicle is driven in a sporty manner or off-road
●When the tires are not properly inflated
●When the tires are very worn
●When tires of a size other than
specified are installed
●When tire chains are installed
●When a compact spare tire or an emergency tire puncture repair kit is
used
●If equipment (snow plow, etc.) that
may obstruct the radar sensor or front camera is temporarily installed to the vehicle

Dynamic Radar Cruise Control with
Road Sign Assist can be
enabled/disabled in on the
multi-information display. ( →P.361)
When the Dynamic Radar Cruise
Control with Road Sign Assist is
operating, while driving down a hill,
the vehicle speed may exceed the
set speed.
In this case, the displayed set vehi-
cle speed will be highlighted and a
buzzer will sound to alert the driver.
■Dynamic radar cruise control can be set when
●The shift lever is in range 2nd or higher.
●Depending on the control mode, this item can be set at the following
speeds. • Vehicle-to-vehicle distance control mode: Approximately 30 km/h (20
mph) or more
• Constant speed control mode:
Approximately 30 km/h (20 mph) or more
■Accelerating after setting the vehi-cle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerat-ing, the set speed resumes. However,
during vehicle-to-vehicle distance con- trol mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.
■Shift position selection
Select a shift position according to the
vehicle speed. If the engine speed is too high or too low, control may be automat-ically canceled.
■Automatic cancelation of vehicle-
to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the follow-
ing situations.
●Actual vehicle speed falls below
approximately 25 km/h (16 mph).
●VSC is activated.
●TRC is activated for a period of time.
