WA R N I N G When the ACC is not being used, turn off the system to avoid unexpected ACC acti- vation. Never operate the ACC from outside the vehicle. The ACC will not decelerate your vehicle and/or give the approach alarm in the fol- lowing cases.• When an object other than a vehicle,such as a pedestrian, is in front. • When a malfunction is detected in thesystem.
The ACC will not decelerate your vehicle in the following cases, but will give the approach alarm.• When the front vehicle is stationary ormoving at an extremely slow speed.• When your brake system has a problem,such as overheating.
The ACC may not be able to maintain the set speed or the distance to a vehicle infront and may not alert the driver, if the system cannot detect the front vehicle properly. Typical situations include: • When a vehicle cuts into your path at aclose distance.• When a vehicle in front is not completelyin your path.• When a vehicle in front is towing atrailer.• When a motorcycle or a bicycle is infront.
• When a vehicle in front is a truck loaded with freight that protrudes rearward from the cargo bed.• When the height of a vehicle in front isextremely low or the road clearance of the vehicle is extremely high.• When driving on a road with alternatingup and down surfaces.• When driving on a curve.• When driving on a bumpy or rough road.• When driving in a tunnel.• When driving in construction zones.• When the rear of your vehicle is weighed down with the weight of passengers and luggage• For up to 2 minutes after starting driv-ing.• When driving in curved sections of roadincluding their entrance/outlet or run- ning beside a closed lane in a traffic workor similar zone.• When the surface of the sensor is coveredwith dirt, snow, ice, etc.• When a front vehicle or an oncomingvehicle is splashing water, snow or dirt.

There are two ways to increase the set speed. The set speed will increase by 1 mph (1.6 km/h) every time you push up the“RES +” switch while the ACC is activated. If you hold the switch pushed up, the set speed increases in 5 mph (8 km/h) incre-ments.
When the accelerator pedal is depressed while driving with the ACC control working,you can accelerate the vehicle beyond the presently set speed.
When the vehicle speed reaches your desired speed, push down and release the “SET -” switch and release the accelerator pedal; the new speed is then set in the system.
CAUTION To maintain proper performance of the ACC:• Always clean the surface of the radar sen- sor.• Avoid impacting the radar sensor or its sur-rounding area.• Do not put a sticker on the radar sensor orits surrounding area.• Do not paint the radar sensor.• Do not install a grill guard.• Do not modify the radar sensor or its sur- rounding area.• Always use tires of the same size, sametype, and same brand, and which have nosignificant wear differences.• Do not modify the vehicle’s suspension.
To increase the set speed
By using the “RES +” switch:
NOTE
There is some time lag until the vehicle begins accelerating to the new set speed after the set speed has been changed. The set speed can be changed even while your vehicle is following a vehicle in frontusing the ACC. In this case, however, although the set speed itself is increased, your vehicle will not accelerate. While the ACC system is in the stationary vehicle hold state, the vehicle speed cannotbe set.
By using the accelerator pedal:
WA R N I N G The ACC braking control and approach alarm functions will not work while the accelerator pedal is depressed.NOTE
The set speed indicator in the multi-informa- tion display will show “---” while the accel- erator pedal is depressed. If the “SET -” button is not pushed down while depressing the accelerator pedal, yourvehicle speed will return to the set speed, after the accelerator pedal is released. When the accelerator pedal is released, the ACCbraking control and approach alarm func- tions may not immediately work.

There are two ways to cancel the ACC con- trol. By pressing the “CANCEL” switch. By depressing the brake pedal.
When the ACC is canceled, the “SET” indi- cator goes off and the following distance indi-cator turns to the standby display. The front vehicle indicator also turns to the standby dis- play when a front vehicle is detected.
In any of the situations listed below, the ACC control is automatically canceled, a buzzer sounds and a message is shown in informa- tion screen of the multi-information display. If the ACC system is in the stationary vehicle hold state, it will also be automatically can- celed and the Electric parking brake will operate. When the ASC is turned off. While ABS, ASC or TCL is activated. When the selector lever is in a position other than “D” (DRIVE). When the parking brake is applied. When the driver’s seat belt is unfastened. When the driver’s door is opened. When the ACC no longer detects any vehicle in front while it is in the stationaryvehicle hold state. When the vehicle is in the stationary vehi- cle hold state for 10 minutes or more.
NOTE
The set speed indication on the display turns to “---” when the accelerator pedal is depressed. This indication remains as long as the pedal is in a depressed position. In certain conditions, the braking control and alarming functions of ACC may not work for a short while after releasing the acceleratorpedal.
To cancel ACC control
NOTE
You can also cancel the ACC control by pressing the ACC ON/OFF switch. If this switch is pressed while
the ACC is ON, the
ACC will be turned off. If you press the “CANCEL” switch or ACC ON/OFF switch to cancel the stationary vehicle hold state, the vehicle will startcreeping.

When the system detects the vehicle mov- ing down a slope while the vehicle is in the stationary vehicle hold state.
If the ACC system judges that the stationary vehicle hold state can no longer be main-tained on a steep slope after your vehicle stops when the vehicle in front stops, the sta- tionary vehicle hold state is cancelled and awarning appears on the information screen of the multi-information display. Depress the brake pedal. If the detection performance of the ACC sys- tem has degraded, such as in the following situations, or if the ACC system judges that it can temporarily not operate, the ACC systemoperation will be cancelled automatically, and then a buzzer will sound and a message will appear to inform the driver. This can occur when
The brake system is overheating due to continuous brake control on long down- hill slope.
This can occur when In adverse weather conditions, such as rain, snow or sand storms, etc. Foreign objects, such as dirt, snow or ice, adhere to the surface of the sensor. A front vehicle or an oncoming vehicle is splashing water, snow or dirt. Driving on a nonbusy road with a few vehicles and obstacles in front.
If the display keeps showing the message, there is a possibility that the ACC has a mal- function. Contact your authorized Mitsubishi Motors dealer. When the ACC system detects an abnormal- ity in the system, the ACC system will beturned off, a buzzer will sound and a message will be displayed in the multi-information display.If the message remains after the operation mode is put in OFF, and then turned back to
ON, contact your authorized Mitsubishi Motors dealer.

N00577300079
The Forward Collision Mitigation system (FCM) is designed to help reduce the risk of a collision with a vehicle or a pedestrian straight ahead of your vehicle. The FCM usesa sensor (A) to determine the distance andrelative speed to a vehicle and a pedestrian in front. The FCM is not designed as an auto- matic driving system or
as a collision avoid-
ance system. When your vehicle is approaching a vehicle or a pedestrian straight-ahead in your pathand the FCM judges that there is the risk of a collision, the system will give audible and visual warnings.When the FCM judges that a collision with the vehicle or the pedestrian straight-ahead is imminent, the system will automaticallyapply moderate braking to warn you to apply the brakes immediately. When the FCM judges that a collision withthe vehicle or the pedestrian straight-ahead is highly unavoidable, the system will apply emergency braking to reduce the severity ofthe collision and, if possible, to avoid the col- lision.
Stop lights are illuminated during automatic braking.
Forward Collision Mitiga- tion system (FCM)
(if so
equipped)
WA R N I N G Before using the FCM, read this entire section to fully understand the limitationsof this system. Failur
e to follow instruc-
tions could result in an accident.
The FCM is designed to help avoid certain frontal collisions or reduce the crash speed in such collisions. It is not a substi- tute for your safe and careful driving. Under certain circumstances, the systemmay not operate or may not detect cor- rectly a vehicle or a pedestrian in front. When your vehicle is approaching a vehi-cle or a pedestrian too closely, take all nec- essary actions to avoid a collision, such as braking and steering, regardless ofwhether the FCM is activated or not. Never rely on the FCM to prevent a colli- sion. Never attempt to test the operation of the FCM. Doing so could cause an accident,resulting in serious injury or death.WA R N I N G
