The Active stability
control (ASC) takes
overall control of the
anti-lock braking sys-
tem, traction control function and skid control function to help maintain the vehicle’s controland traction. Please read

On slippery surfaces, the traction control function prevents the drive wheels from spin- ning excessive, thus helping the vehicle tostart moving from a stopp
ed condition.
It also
provides sufficient driv
ing force and steering
performance as the vehicle turns while press-ing the acceleration pedal.
N00559300019
The skid control function is designed to helpthe driver maintain control of the vehicle on slippery roads or during rapid steering
CAUTION If the warning display appears while the engine is running, have
the vehicle inspected
by an authorized Mitsubishi Motors dealer or a repair facility of
your choice as soon as
possible. It may become harder to turn thesteering wheel.
Active stability control (ASC)
CAUTION Do not over-rely on the ASC. Even the ASC cannot prevent the natural laws of physics from acting on the vehicle. This system, like any other system, has
limits and cannot help
you to maintain traction and control of the vehicle in all circumstances. Reckless driv- ing can lead to accident
s. It is the driver’s
responsibillty to drive carefully, This means taking into account the traffic, road and envi- ronmental conditions. Be sure to use the same specified type and size of tire on all four
wheels. Otherwise, the
ASC may not work properly. Do not install any aftermarket limited slip differential (LSD) on your vehicle. The ASC may stop functioning properly.NOTE
An operation noise may be emitted from the engine compartment in the following situa-tions. The sound is associated with checkingthe operations of the ASC. At this time, you may feel a shock from the brake pedal if you depress it. These do not
indicate a malfunc-
tion. • When the ignition switch is set to the “ON” position. • When the vehicle is driven for a while after the engine is turned on.
When the ASC is acti
vated, you may feel a
vibration in the vehicl
e body or hear a whin-
ing sound from the engine compartment.This indicates that th
e system is operating
normally. It does not i
ndicate a malfunction.
When the anti-lock braking system warning light is illuminated, the ASC is not active.

The ASC is automatically activated when the ignition switch is turned to the “ON” posi- tion. You can deactivate
the system by press-
ing down the ASC OFF switch for 3 seconds or longer. When the ASC is deactivated, the indica- tor will turn on. To reactivate the ASC, momentarily press the ASC OFF switch; the indicator is turned off.
N00559501249
NOTE
The skid control func
tion operates
at speeds
of about 9 mph (15 km/h) or higher.
ASC OFF switch
CAUTION For safety reasons, the ASC OFF switch should be operated when your vehicle isstopped. Be sure to keep the ASC on while driving in normal circumstances.NOTE
Using the ASC OFF switch turns off both the stability control func
tion and the traction
control function. When moving out of mud, sand or fresh snow, pressing the accelerator pedal may not allow the engine speed to increase. In suchsituations, temporarily turning off ASC with the ASC OFF switch will make it easier to move out your vehicle. If you continue to pre
ss the ASC OFF switch
after the ASC is turned off, the “mistakenoperation protection f
unction” wi
ll activate
and the ASC will turn back on.

y/ASC indicator
The display/indicator will blink when the ASC is operating.
-
ASC OFF indicator This indicator will turn on when the ASC is turned off with the ASC OFFswitch.
CAUTION When display/indicator blinks, ASC is operating, which means th
at the road is slip-
pery or that your vehicle’s wheels are begin- ning to slip. If this happens, drive slower. If the temperature in the braking system con- tinues to increase due
to continuous brake
control on a slippery road surface, the indicator will blink. To prevent the brake system from overheat- ing, the brake control of the traction control function will be te
mporarily suspended.
The engine control of
the traction control
function and normal br
ake operation will not
be affected.Park your vehicle in a safe place. When the temperature in the braking system has come down, the indicator will be turned off and the traction control function will start operat- ing again.

Cruise control is an automatic speed control system that keeps a set speed. It can be acti-vated at speeds from about 25 mph (40 km/h). Cruise cont
rol does not work at
speeds below about 25 mph (40 km/h).
NOTE
The indicator may come on when you start the engine. This means that the battery voltage momentarily dropped when theengine was started. It
does not indicate a
malfunction, provided th
at the display goes
out immediately. When a spare tire has been put on your vehi- cle, the gripping ability of the tire will be lower, making it more
likely that the dis-
play/indicator will blink.

(if so equipped)
When you do not wish to drive at a set speed, turn off the cruise control for safety. Do not use cruise control when driving con- ditions will not allow
you to stay at the same
speed, such as in heavy traffic or on roads that are winding, icy, snow-covered, wet,slippery, on a steep downhill slope.NOTE
Cruise control may not
be able to keep your
speed on uphills or downhills. Your speed may decr
ease on a steep uphill.
You may use the accelerator pedal if you want to stay at your set speed. Your speed may increase to more than the set speed on a steep downhill. You have to use the brake to control your speed. As a result,the set speed driving is deactivated.

While the ACC is turned on, indicators for the ACC are shown in the multi information display.
WA R N I N G Before using the ACC, read this entire sec- tion to understand th
e limitations of this
system. Failure to follow instructionscould result in an accident. Never rely solely on the ACC. The ACC is not a collision avoidance system or an automatic driving system. It is designed to use only limited brak
ing and is never a
substitute for your safe and careful driv- ing. Always be ready to apply the brakes manually.
