With the ACC turned on, push down the“SET -” switch while
driving, and when your
vehicle reaches your de
sired speed, release
the “SET -” switch. The ACC will activateand initiate the speed control to maintain theset speed.The set indicator comes on, the set speed isindicated and the follow
ing distance indicator
changes to the ‘active’ will sound.
You can set the speed anywhere from approx-imately 25 mph (40 km/h) to 110 mph (180km/h).While a vehicle in front
is being detected and
your vehicle speed is
between a
pproximately
6 mph (10 km/h) and 25 mph (40 km/h), youcan activate the ACC. In this case, the setspeed will be set at 25 mph (40 km/h).The ACC cannot otherwis
e be activated while
your vehicle is traveling less than 25 mph (40km/h) or greater than 110 mph (180 km/h).

The ACC will maintain the distance to thefront vehicle and will
apply the brakes auto-
matically when the system judges braking isnecessary. The distance can be selected fromthree levels.
To activate ACC control
NOTE
When any of the following conditions arepresent, the ACC will not activate. • When your vehicle speed is lower thanapproximately 6 mph (1
0 km/h) or greater
than 110 mph (180 km/h).• When your vehicle is driven at speedsbetween approximately 6 mph (10 km/h)and 25 mph (40 km/h) and the ACC is notdetecting a vehi
cle in front.
• When ASC is in the OFF position.• While ABS, ASC or TCL is activated.• When the selector lever

When the front vehicle stops, the ACC willautomatically apply the brakes to stop yourvehicle.A few seconds after your vehicle has stopped,the ACC will release the brakes and yourvehicle will start to move or creep slowly.You must apply the brakes to keep your vehi-cle stationary.
When the ACC no longer detects a vehicle infront, the buzzer will sound, the vehicle sym-bol in the display will disappear and yourvehicle will slowly accelerate to the setspeed.
NOTE
If the brake pedal is not depressed within 2seconds after your vehi
cle has been stopped
by the ACC, a warni
ng buzzer will sound,
the above warning will be shown in the multiinformation display to alert the driver, andthe ACC control will be canceled.When depressing the brake pedal while theautomatic brake is applied, the brake pedalwill feel firm. This is normal. Depress thebrake pedal harder to
apply greater braking
force.During the automatic braking, operationsounds may be heard. This is normal.WA R N I N GNever leave the vehicle while it is beingstopped by the ACC.
WA R N I N GYour vehicle may accelerate up to the setspeed in the following situations. Applythe brake, if necessary, to slow down.• When your vehicle no longer follows thevehicle in front, e.g. at a freeway exit orwhen your vehicle or
the vehicle in front
changes its lane.• When driving on a curve.

While the ACC is activated, if your vehicle isapproaching too closely to the vehicle infront, the ACC gives a warning by sounding abuzzer and displaying a message. Apply thebrakes to maintain the appropriate distance tothe vehicle in front.When the vehicle in
front has changed its
course or lane, if a stationary vehicleappears in front you
r vehicle, the ACC
will not decelerate your vehicle.
Approach alarm
WA R N I N GWhen the ACC is not being used, turn offthe system to avoid
unexpected ACC acti-
vation.Never operate the AC
C from outside the
vehicle.WA R N I N G
The ACC will not decelerate your vehicleand/or give the approach alarm in the fol-lowing cases.• When an object other than a vehicle,such as a pedestri
an, is in front.
• When a malfunction is detected in thesystem.
The ACC will not decelerate your vehiclein the following cases, but will give theapproach alarm.• When the front vehicle is stationary ormoving at an extr
emely slow speed.
• When your brake system has a problem,such as overheating.
The ACC may not be able to maintain theset speed or the dist
ance to a vehicle in
front and may not alert the driver, if thesystem cannot detect the front vehicleproperly. Typical situations include: • When a vehicle cuts
into your path at a
close 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 fr
ont is a truck loaded
with freight that protrudes rearwardfrom the cargo bed.WA R N I N G
• When the height of a vehicle in front isextremely low or the road clearance ofthe vehicle is extremely high.• When driving on a r
oad with alternating
up 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 weigheddown with the weight of passengers andluggage• For up to two 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 th
e sensor is covered
with dirt, snow, ice, etc.• When a front vehicle or an oncomingvehicle is splashing wa
ter, snow or dirt.

There are two ways to increase the set speed.The set speed will increase by 1 mph (1km/h) every time you push up the “RES +”switch while the ACC is activated. If youhold the switch pushed up, the set speedincreases in 5 mph (5 km/h) increments.
When the accelerator
pedal is depressed
while driving with the ACC control working,you can accelerate the vehicle beyond thepresently set speed.When the vehicle speed reaches your desiredspeed, push down and release the “SET -”

Never use the ACC in the following situa-tions:• In heavy traffic.• On winding roads.• On slippery roads, such as icy, snow-cov-ered or dirt roads.• In adverse weather conditions, such asrain, snow or sand storms, etc.• On steep downslopes.• When the inclination of a road fre-quently changes.• When the approach alarm frequentlysounds.• When your vehicle is towed or is towinganother vehicle.• When your vehicle is on a chassis dyna-mometer or free rollers.• When tire inflation pressures are notadequate.• When the temporary sp
are tire is being
used.• When the radar sensor and/or its sur-rounding area are damaged or deformed.WA R N I N G
CAUTIONTo 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 whileyour vehicle is followi
ng a vehicle in front
using the ACC. In this case, however,although the set speed itself is increased,your vehicle will
not accelerate.

sounds and a message is shown in the multi-information display.When your vehicle stops.When the ASC is turned off.While ABS, ASC or TCL is activated.When the selector lever is in a positionother than “D” (DRIVE) and “Ds”(DOWNSHIFT & SPORTY DRIVING).When the parking brake is applied.
When the ACC system determines that itsperformance has been degraded, a buzzer willsound and a message will be displayed in themulti information display.This can occur whenForeign objects, such as dirt, snow or ice,adhere to the surface
of the radar sensor.
In adverse weather conditions, such asrain, snow or sand storms, etc.A front vehicle or an oncoming vehicle issplashing water, snow or dirt.Driving on a nonbusy road with a fewvehicles and obsta

The brake system is
overheating due to
continuous brake control on long down-hill slope.
If the display keeps showing the message,there is a possibility that the ACC has a mal-function. Contact your authorized MitsubishiMotors dealer.When the ACC system
detects an abnormal-
