CAUTION
■Handling the camera sensors (if equipped)
Observe the following to ensure that the PCS functions effectively:
●Keep the windshield clean at all times.
PCS effectiveness may be reduced due to the presence of raindrops, condensa-
tion, ice or snow on the windshield.
●Do not subject the camera sensor to a st rong impact or force, and do not disas-
semble the camera sensor.
●Do not change the installation position of the camera sensor, or remove and rein-
stall it. The direction of the camera sensor is precisely adjusted.
●When the windshield fogs up, use the wi ndshield defogger to dry the windshield.
During cold weather, using the heater with air blowing to the feet may allow the
upper part of the windshield to fog up, having a negative effect on the images.
●Do not place anything on the dashboard.
Images reflected on the windshield may reduce the effectiveness of the camera
sensor.
●Do not scratch the camera lens, or let it get dirty.
●Do not attach a sticker or other items to the windshield near the camera sensor.
■Headlights (vehicles with camera sensors)
●Observe the following to ensure proper near-infrared ray projection:
• Keep the headlights clean at all times.
• The detection performance may deteriorate if the high beams are misaligned
or inoperative.
●The near-infrared ray transmitters project strong energy that is not visible.
Although the transmitters normally turn off when the vehicle is stopped, never
look into the headlights for your safety.

CAUTION
■Determining the direction the driver is facing and whether the driver’s eyes are
open or closed (vehicles with driver monitor system)
The direction the driver is facing and whether the driver’s eyes are open or closed
may not be determined correctly if the following conditions exist:
●There is an object between the driver monitor sensor and the driver’s face, such
as when the sensor is blocked.
●A part of the driver’s face is covered.
●The sensor or the driver’s face is exposed to intense light such as sunlight.
●The driving posture is improper.
●The vehicle is parked.
■Handling the driver monitor sensor (vehicles with driver monitor system)
Observe the following to ensure the driver monitor sensor can function effectively.
Failure to do so may result in a malfunction or may prevent the system from cor-
rectly determining the direction the driver is facing and whether the driver’s eyes
are open or closed, resulting in an unexpected accident.
●Do not disassemble, damage, lift or pull on the sensor.
●Do not touch the sensor while driving.
●Do not wet or spill water on the sensor.
●Do not drop anything on or allow anything to hit against the sensor. Do not sub-
ject the sensor to an impact.
●Make sure that there are no scratches, dirt or stickers on the side of the sensor
that faces the driver.
●Do not place any objects in front of the side of the sensor that faces the driver or
cover the sensor.

◆Warning for the approaching vehicle (emergency flashers)
When the system determines that there is a risk of a rear-end collision,
the emergency flashers flash to warn the driver of the vehicle
approaching from the rear.
◆Whiplash mitigation (pre-crash intelligent head restraints*)
When a vehicle draws near from behind and the system has deter-
mined that the possibility of a rear-end collision is very high, the sensor
in each front head restraint detects the position of the occupant’s head
and the pre-crash intelligent head restraint moves, contributing to
whiplash mitigation when a rear-end collision occurs.
*: For vehicles with a foldable head restraint, driver’s seat only.
Rear Pre-Crash Safety system
: If equipped
When the radar sensor detects the possibility of a rear-end collision,
the rear pre-crash safety system will operate to warn the approaching
vehicle and mitigate whiplash.

The rear radar sensor detects
objects approaching from behind
and determines whether a rear-end
collision is imminent based on the
position, speed and heading of the
object before it happens.
■System operating conditions
When the power switch is in ON mode and there is a possibility of a rear-end colli-
sion due to a vehicle in the same lane approaching from the rear, the system oper-
ates if all of the following conditions are met:
●Warning for the approaching vehicle (emergency flashers):
• The relative speed difference between your vehicle and the vehicle approach-
ing from behind is greater than about 30 km/h (18 mph).
• When the vehicle is stationary or moving forward while the brake pedal is
depressed.
• When the turn signal lights and emergency flashers are off.
●Whiplash mitigation (pre-crash intelligent head restraints):
• The relative speed difference between your vehicle and the vehicle approach-
ing from behind is greater than about 15 km/h (9 mph).
• Your vehicle is stopped or moving forward.
■Whiplash mitigation
The pre-crash intelligent head restraint may not stop in the proper position if a hat is
worn or the occupant’s hair is bound at the back.
