3 Power steering system
N00518000206
The power steering system has mechanical steering capability
in case the power assist is lost. If the hydraulic pressure is
interrupted for some reason (such as engine stalling), you will
still be able to steer your vehicle.
If the power assist is lost, you will notice it takes much more
effort to steer and that there is much more “free play” in the
steering wheel. If this happens, take your vehicle to an autho-
rized Mitsubishi Motors dealer or a repair facility of your
choice.
Active stability control (ASC)
N00559100091
The active stability control (ASC) takes overall control of the
anti-lock braking system, traction control function and skid
control function to help maintain the vehicle’s control and trac-
tion. Please read this section in conjunction with the page on
the anti-lock braking system, traction control function and skid
control function.
Anti-lock braking system → P. 3 - 1 3 5
Traction control function → P. 3 - 1 4 0
Skid control function → P. 3 - 1 4 0
WA R N I N G
!

Never turn off the engine while the vehicle is mov-
ing, or your ability to steer the vehicle may be seri-
ously reduced.CAUTION
!

Do not leave the steering wheel turned all the way in
one direction. This can cause damage to the power
steering system.
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
driving can lead to accidents. It is the driver’s
responsibillty to drive carefully, This means taking
into account the traffic, road and environmental
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 differen-
tial (LSD) on your vehicle. The ASC may stop func-
tioning properly.

NOTE

An operation noise may be emitted from the engine com-
partment in the following situations. The sound is associ-
ated with checking the 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 malfunction.
 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 activated, you may feel a vibration in
the vehicle body or hear a whining sound from the engine
compartment.
This indicates that the system is operating normally. It
does not indicate a malfunction.


When the anti-lock braking system warning light is illu-
minated, the ASC is not active.
Traction control function
N00559200047
On slippery surfaces, the traction control function prevents the
drive wheels from spinning excessive, thus helping the vehicle
to start moving from a stopped condition. It also provides suffi-
cient driving force and steering performance as the vehicle
turns while pressing the acceleration pedal.Skid control function
N00546800023
The skid control function is designed to help the driver main-
tain control of the vehicle on slippery roads or during rapid
steering maneuvers. It works by controlling the engine output
and the brake on each wheel.NOTE

The skid control function operates at speeds of about 9
mph (15 km/h) or higher.
CAUTION
!

When driving a vehicle on a snowy or icy road, be
sure to install snow tires and drive the vehicle at
moderate speeds.

“ASC OFF” switch
N00559400140
The ASC is automatically activated when the ignition switch is
turned to the “ON” position. You can deactivate the system by
pressing down the “ASC OFF” switch for 3 seconds or longer.
When the ASC is deactivated, the display will be illumi-
nated. To reactivate the ASC, momentarily press the “ASC
OFF” switch ; the display is turned off.
NOTE

Using the “ASC OFF” switch turns off both the skid con-
trol function 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 such situations, temporarily turning off ASC
with the “ASC OFF” switch will make it easier to move
out your vehicle.


If you continue to press the “ASC OFF” switch after the
ASC is turned off, the “mistaken operation protection
function” will activate and the ASC will turn back on.
CAUTION
!

For safety reasons, the “ASC OFF” switch should be
operated when your vehicle is stopped.


Be sure to keep the ASC on while driving in normal
circumstances.

indicator
(if so equipped)
N00546500059
Indicator (if so equipped)
Display type 1
Display type 2
NOTE

The display may come on when you start the engine.
This means that the battery voltage momentarily dropped
when the engine was started. It does not indicate a mal-
function, provided that the display goes out immediately.


When a spare tire has been put on your vehicle, the grip-
ping ability of the tire will be lower, making it more likely
that the display will blink.
-ASC operation display
When the ASC is operating, the information screen in the
multi-information display will change and the ASC opera-
tion display will blink.
-ASC OFF display
The display is displayed when the ASC has been deac-
tivated with the “ASC OFF” switch.
-ASC indicator (if so equipped)
Indicator blinks when the ASC is operating.
CAUTION
!

When display blinks, ASC is operating, which
means that the road is slippery or that your vehicle’s
wheels are beginning to slip. If this happens, drive
slower.


If the temperature in the braking system continues
to increase due to continuous brake control on a
slippery road surface, the display will blink. To
prevent the brake system from overheating, the
brake control of the traction control function will be
temporarily suspended. The engine control of the
traction control function and normal brake opera-
tion will not be affected. Park your vehicle in a safe
place. When the temperature in the braking system
has come down, the display will be turned off and
the traction control function will start operating
again.

ASC warning display
N00546600050
Indicator (if so equipped)
Warning display type 1
Warning display type 2
If an abnormal condition occurs in the system while driving,
the warning display will be displayed at the same time.
CAUTION
!

The system may be malfunctioning.
Park your vehicle in a safe place and stop the engine.
Restart the engine again and check whether the
warning display, the display go out. If the warn-
ing display goes out, there is no abnormal condition.
If the warning display does not go out or appears
frequently, it is not necessary to stop the vehicle
immediately, but you should have your vehicle
inspected by an authorized Mitsubishi Motors
dealer or a repair facility of your choice as soon as
possible.

Cruise control
N00518300502
Cruise control is an automatic speed control system that keeps
a set speed. It can be activated at speeds from about 25 mph
(40 km/h). Cruise control does not work at speeds below about
25 mph (40 km/h).NOTE

Cruise control may not be able to keep your speed on
uphills or downhills.


Your speed may decrease 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.
CAUTION
!

When towing the vehicle with only the front wheels
or only the rear wheels raised off the ground, do not
place the ignition switch in the “ON” position. Plac-
ing the ignition switch in the “ON” position could
cause the ASC to operate, resulting in an accident.
Note that the correct towing method depends on the
transmission type and the vehicle’s drive configura-
tion.
For details, refer to “Towing” on page 6-18.
CAUTION
!

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 conditions
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.


On vehicles equipped with manual transaxle, do not
move the gearshift lever to the “N” (Neutral) posi-
tion while driving at a set speed without depressing
the clutch pedal. The engine will run too fast and
might be damaged.
