If the vehicle is trapped in the railway
crossing because the system is activated as
the crossing barrier is misrecognised as an
obstacle, escape from the railway crossing
without any panic by one of the following
methods.
• Release the foot from the accelerator
pedal and lightly depress the pedal again.
• Turn the system OFF. (Continuously
press the Forward Collision Mitigation
System (FCM) and Ultrasonic misaccel-
eration Mitigation System (UMS)
ON/OFF switch for more than 3 sec-
onds.)
• Continuously depress the accelerator
pedal for more than 5 seconds.
• Repeat to press the accelerator pedal
quickly to its full stroke more than
3 times.
Do not perform inspection of the system
operation on your own. Depending on the
situation, this may cause the system to not
operate properly and lead to a serious
accident.
CAUTION
The Ultrasonic misacceleration Mitigation
System does not operate in the following
conditions:
• The operation mode is other than ON.
WARNING
• The Ultrasonic misacceleration Mitigation
System is set to OFF by operating the For-
ward Collision Mitigation System (FCM)
and Ultrasonic misacceleration Mitigation
System (UMS) ON/OFF switch.
• The Forward Collision Mitigation System
(FCM) and Ultrasonic misacceleration Mit-
igation System (UMS) OFF indicator lights
up.
• The selector lever is set to the “P” (PARK)
or “N” (NEUTRAL) position.
It sometimes happens that a motorcycle,
bicycle or pedestrian are detected as obsta-
cles, but these are not the object of the Ultra-
sonic misacceleration Mitigation System
operation.
The Ultrasonic misacceleration Mitigation
System may not operate in the following
conditions.
• The sensors or surroundings have been
wiped by hand.
• The stickers or accessories have been
attached to the sensors or surroundings.
• When there is an extremely change in the
outside temperature.
• Under adverse weather conditions (rain,
strong winds, snow, sand storms, etc.)
• When approaching an obstacle too closely.
• When a vehicle cuts in front or behind your
vehicle very closely.
• When only a part of the obstacle is within
the detection areas of the sensor.
CAUTION
• When the rain, snow, water or dirt adheres
to the sensor.
• When the sensor is extremely hot or cold
(while the vehicle is parked for a long
period of time under a blazing sun or in
cold weather).
• Immediately after engine starting.
• When driving on a road with many and suc-
cessive curves, including when passing
their entrances and outlets.
• When driving on a road with steep and
alternating up and down slopes.
• When a road surface is surging, and there is
unevenness.
• When the system judges driver’s steering or
gear shifting actions as evasive actions to
avoid collision.
• For a short period after the system judges
the repeated depression of the accelerator
pedal at a few seconds interval as a release
operation.
• When the vehicle body is extremely
inclined by carrying heavy loads or
improper adjustment of the tyre pressure.
• When the driving is unstable due to an acci-
dent or trouble.
• The system receives ultrasonic noise from
other sources (the horns of other vehicles,
motorcycle engines, brakes, radios, pouring
rain, splashing water, snow traction device
(tyre chains), etc.).
