OPERATING YOUR VEHICLE
Frontal collision warning
(1)
54P000353
If your vehicle gets too close to the vehicle
ahead as described below, the interior
buzzer sounds, the indicator (1) appears
on the information display at the same
time, to promote deceleration.
• The vehicle ahead of you slows down
abruptly.
• Another vehicle cuts in front of you.
Depress the brake pedal, and keep an
appropriate distance from the vehicle
ahead. The buzzer timing of frontal colli-
sion warning varies depending on the vehi-
cle speed and a following distance
between your vehicle and the vehicle
ahead.
There are different frontal collision warning
operations in adaptive cruise control sys-
tem and radar brake support system.
Therefore, the interior buzzer in adaptive
cruise control system sounds a little earlier
than the buzzer in radar brake support sys-
tem. For details of frontal collision warning
in radar brake support system, refer to
3-39
"Radar brake support system (if equipped)"
in this section.
WARNING
• Do not use the adaptive cruise con-
trol system in a heavy traffic area
where the frontal collision warning
frequently activates.
• Even if the distance between your
vehicle and the vehicle ahead is
short, frontal collision warning may
not alert you under the following
circumstances:
– The vehicle ahead of you is going
at almost the same speed as, or
faster than your vehicle.
– When the vehicle ahead of you is
going away from your vehicle.
– Right after setting up to the
desired speed.
– While depressing the accelerator
pedal or right after releasing the
pedal.
– While decelerating by depressing
the brake pedal.
