The detection areas of the front and rear sen-
sors are limited. Moreover, the sensors are
unable to detect low or thin objects or objects
near the rear bumper. Make sure to check the
surroundings as you operate the vehicle in a
safe manner.
• When the obstacle is not horizontal to the
ground or not perpendicular to the vehicle
traveling direction.
The Ultrasonic misacceleration Mitigation
System operation can be cancelled when the
system judges the handle operation as eva-
sive actions or when the obstacle moves out
of the detectable area of the sensor.
The Ultrasonic misacceleration Mitigation
System may be triggerd operate in the fol-
lowing situations.
• When the surrounding vehicle or oncoming
vehicle drives blowing up the water, snow
or sand on the road.
• When the rain, snow, water or dirt adheres
to the sensor.
• When there are objects, steps or projections
on the road surface.
• When the parking gate or railway barrier is
raised imperfectly.
• When running the road, the gradient
changes suddenly.
• When passing through the mass of the
steam, fog.
• When driving in close to the vehicle ahead,
and when stopping in close to the for-
ward/backward vehicle or a wall.
• When there is an obstacle in a curb or an
intersection.
• When passing through a vinyl curtain etc.
• When the surrounding area is overgrown
with weeds.
CAUTION
• When leaving from a parallel parking.
• When there is a ultrasonic near your vehicle
by horn of other vehicle, engine sound of a
motorcycle, air brake noise of a large vehi-
cle, a vehicle detector and sonar of a vehi-
cle etc..
• When an electrical equipment on the mar-
ket (radio antenna etc.) is installed near the
sensor.
• When driving on a gravel road.
Turn off the system by pressing the Forward
Collision Mitigation System (FCM) and
Ultrasonic misacceleration Mitigation Sys-
tem (UMS) ON/OFF switch beforehand
when the vehicle is placed in any of the fol-
lowing situations as the system can operate
unexpectedly.
• When using an automatic car wash.
• When returning the fallen wheel in a ditch
or escaping from mud.
• When using a vehicle elevator or a multi-
storey car park.
• Do not modify the suspension of your vehi-
cle.
• When your vehicle’s wheels are driven by
the engine on a lift.
• When your vehicle is towed or your vehicle
tows another vehicle.
• When your vehicle is carried on a truck.
• When enjoying sports driving on a circuit.
• When your vehicle is on a chassis
dynamometer or free rollers.
CAUTION
• When the tyre pressure is not proper.
• When tyre chains are attached.
Improperly handling the system components
may result in such problems as degraded sen-
sor performance and ultimately in an acci-
dent.
Be sure to take the following precautions to
keep the system in good operating condi-
tions.
• Avoid application of strong shock loads to
the sensor.
• The sensor should be kept clean.
• Do not cover the sensor with a sticker or
anything.
• Do not modify the suspension of your vehi-
cle.
If the bumper has been exposed to an impact,
the sensors may fail and prevent the system
from functioning properly. Have the vehicle
inspected at an authorised MITSUBISHI
MOTORS dealer.
