3Anti-lock braking system
N00517900224
The anti-lock braking system helps prevent the wheels from
locking up when braking. This helps you keep control of your
vehicle and its direction. Driving hints
When using the anti-lock brakes (sudden braking), steer-
ing is slightly different from normal driving conditions.
Use the steering wheel carefully.

Always keep a safe distance from the vehicle in front of
you. Even if your vehicle is equipped with the anti-lock
braking system, leave a greater braking distance when:
• Driving on gravel or snow-covered roads.
• Driving on uneven road surfaces.

Operation of anti-lock braking system is not restricted to
situations where brakes are applied suddenly. This system
may also prevent the wheels from locking when you drive
over manholes, steel roadwork plates, road markings, or
any uneven road surface.

When the anti-lock braking system is in use, you may feel
the brake pedal vibrating and hear a unique sound. You
may also feel as if the pedal resists being pressed.
In this situation, simply hold the brake pedal down
firmly. Do not pump the brake, which will result in
reduced braking performance.
CAUTION
!
The anti-lock braking system cannot prevent acci-
dents. It is your responsibility to take safety precau-
tions and to drive carefully.
To prevent failure of the anti-lock braking system,
be sure all four wheels and tires are the same size
and the same type.

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 Active 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.3-82
Traction control function → P. 3 - 8 5
Skid control function → P. 3 - 8 6
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
N00559400052
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 illumi-
nated. 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
N00546900011
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 indicators will illuminate at
the same time, or the indicator will blink.
In these cases, follow these procedures:
[If the and indicators continuously illuminate]• Park your vehicle in a safe place and stop the
engine. Restart the engine again and check
whether the and indicators go out. If these
indicators go out, there is no abnormal condition.
If the 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 function 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 indi-
cator 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.
