Anti-lock braking system warning light
N00531600313
This light comes on in the event of a malfunction in the anti-
lock braking system. It will also come on as a self-check for a
few seconds when the ignition key is turned to the “ON” posi-
tion. Always make sure that the light goes out before beginning
to drive.
If the warning light illuminates while driving
N00531700473

Since there is always a risk of your vehicle becoming
unstable if you apply the brakes suddenly, be sure to brake
gently and do not attempt high-speed driving. Be sure to
stop the vehicle in a safe place. Test the system by restart-
ing the engine and driving at a speed of about 12 mph (20
km/h) or higher.

If the light goes out, there is no abnormal condition. If the
light does not go out after driving as instructed here, or if
it comes on again, the anti-lock braking system is not
functioning. Only the ordinary braking system is function-
ing. If this happens, take your vehicle to an authorized
Mitsubishi Motors dealer or a repair facility of your
choice and have the system checked as soon as possible.
CAUTION
!
If the anti-lock braking system warning light comes
on and stays on after starting the engine or while
driving, it means that the anti-lock braking system is
not working and that only the standard brake sys-
tem is available. (The standard brake system will
still work properly.) If this happens, take your vehi-
cle to an authorized Mitsubishi Motors dealer or a
repair facility of your choice as soon as possible.

NOTE
After your vehicle is driven a short distance after starting
the engine, you will hear a whining sound and the sound
of a motor operating coming from the engine compart-
ment. These are the normal sounds the anti-lock braking
system makes when performing a self-check. It does not
indicate a malfunction.

The anti-lock braking system can be used after the vehicle
has reached a speed over approximately 6 mph (10 km/h).
It stops working when the vehicle slows below approxi-
mately 3 mph (5 km/h).

After driving on snow or icy roads, remove any snow and
ice which may have been left around the wheels. On vehi-
cles that have an anti-lock braking system, be careful not
to damage the wheel speed sensors (A) or the cables
located at each wheel.

3-84 Features and controls
3Active stability control (ASC)
N00559100088
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. Also refer to the following pages on the anti-lock braking
system, traction control function and skid control function.
Anti-lock braking system (ABS) → P. 3 - 8 1
Traction control function → P. 3 - 8 4
Skid control function → P. 3 - 8 5
NOTE
A whining sound may be heard from the engine compart-
ment in the following situations. The sound is associated
with the ASC self-check operations. It does not indicate a
malfunction.
• When the ignition key 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
N00559200050
On slippery surfaces, the traction control function prevents the
drive wheels from spinning excessively, thus helping the vehi-
cle to start moving from a stopped condition. It also provides
sufficient driving force and steering performance as the vehicle
turns while pressing the acceleration pedal.
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
responsibility 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.
CAUTION
!
When driving a vehicle on a snowy or icy road, be
sure to install snow tires and drive the vehicle at
moderate speeds.

Skid control function
N00546800036
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.
ASC OFF switch
N00559400225
The ASC is automatically activated when the ignition key 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 / indicator will be illu-
minated. To reactivate the ASC, momentarily press the ASC
OFF switch; the / indicator is turned off. Except for vehicles with headlight leveling

NOTE
Using the ASC OFF switch turns off both the skid control
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 deactivate the
ASC, using the ASC OFF switch.

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.
After the “mistaken operation protection function” is acti-
vated, it will not be possible to turn the ASC off.
To turn the system off again, return the ignition key to the
“ACC” or “LOCK” position, restart the engine and press
the ASC OFF switch.
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.Vehicles with headlight leveling

ASC indicator, ASC OFF indicator
N00546900037
The indicators should illuminate when the ignition key is
turned to the “ON” position, and should turn off after a few
seconds.
If the indicator stays on or does not illuminate when the igni-
tion key is turned to the “ON” position, have the vehicle
inspected by an authorized Mitsubishi Motors dealer or a repair
facility of your choice as soon as possible.
/ indicator blinks when the ASC is operating.
/ indicator is illuminated when the ASC is deactivated.
NOTE
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 / indicator will blink.

CAUTION
!
When / indicator blinks, the ASC is operating,
which means that the road is slippery or that your
vehicle’s wheels are beginning to slip. If this hap-
pens, drive slower.
CAUTION
!
If an abnormal condition occurs in the system while
driving, the and / and indicators will illu-
minate at the same time, or the / indicator will
blink.
In these cases, follow these procedures:

[If the and / and indicators continuously
illuminate]• Park your vehicle in a safe place and stop the
engine. Restart the engine again and check
whether the and / and indicators go out.
If these indicators go out, there is no abnormal
condition.
If the and / and indicators remain on
even after your vehicle is driven a short distance
after re-starting the engine, have the vehicle
inspected by an authorized Mitsubishi Motors
dealer or a repair facility of your choice as soon as
possible.[If the / indicator blinks]• If the temperature of the braking system increases
excessively, due to continuous brake control on a
slippery road surface, the / indicator will
blinks and operation of the traction control func-
tion will be suspended to protect the brake system.
(Normal operation of the vehicle 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 operating
again.CAUTION
!
CAUTION
!
If the vehicle is towed with the ignition key in the
“ON” position and only the front wheels or only the
rear wheels raised off the ground, the ASC may
operate, resulting in an accident. When towing the
vehicle with the front wheels raised, keep the igni-
tion key in the “LOCK” or “ACC” position. When
towing the vehicle with the rear wheels raised, keep
the ignition key in the “ACC” position.
Refer to “Towing” on page 6-20.

3 Power steering system
N00518000307
The power steering system operates while the engine is run-
ning. It helps reduce the effort needed to turn the steering
wheel.
The power steering system has mechanical steering capability
in case the power assist is lost. If the power assist is lost for
some reason, 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 authorized
Mitsubishi Motors dealer or a repair facility of your choice.
Cruise control
N00518300355
Cruise control is an automatic speed control system. It lets you
keep the same driving speed. Cruise control can be used at
speeds of about 25 mph (40 km/h) or more. It is especially use-
ful for freeway driving. Cruise control does not work at speeds
below about 25 mph (40 km/h).
WA R N I N G
!
Do not stop the engine while the vehicle is moving.
Stopping the engine would make the steering wheel
extremely hard to turn, possibly resulting in an acci-
dent.
CAUTION
!
Do not leave the steering wheel turned all the way in
one direction. This can cause damage to the power
steering system.

B- Cruise control lever
CAUTION
!
For safety reasons, deactivate cruise control system
using the main switch (A) when you are not using
the cruise control system.
