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

Tire pressure monitoring system warning light
N00554800093
When the ignition key is turned to the “ON” position, this light
normally illuminates and goes off a few seconds later.
If one or more of the vehicle tires (except for the compact spare
tire) is significantly under-inflated, however, this light will
remain illuminated while the key is in the “ON” position.
Refer to “If the warning light illuminates while driving” on
page 3-99 and take the necessary measures.
CAUTION
!
If the tire pressure monitoring system warning light
does not illuminate when the ignition key is turned
to the “ON” position, it means that the tire pressure
monitoring system is not working properly. Have
the system inspected by an authorized Mitsubishi
Motors dealer.
In such situations, a malfunctioning of the system
may be preventing the monitoring of the tire pres-
sure. Avoid sudden braking, sharp turning and
high-speed driving.

If a malfunction is detected in the tire pressure mon-
itoring system, the tire pressure monitoring system
warning light will blink for approximately 1 minute
and then remain continuously illuminated. The
warning light will issue further warnings each time
the engine is restarted as long as the malfunction
exists.
Check to see whether the warning light goes off after
few minutes of driving.
If it then goes off during driving, there is no prob-
lem.
However, if the warning light does not go off, or if it
blinks again when the engine is restarted, have the
vehicle inspected by an authorized Mitsubishi
Motors dealer.
In such situations, a malfunctioning of the system
may be preventing the monitoring of the tire pres-
sure. For safety reasons, when the warning light
appears while driving, avoid sudden braking, sharp
turning and high-speed driving.

If the warning light illuminates while driving
N00532800341
1. If the low tire pressure monitoring system warning light
illuminates, avoiding hard braking, sharp steering maneu-
vers and high speeds. You should stop and adjust the tires
to the proper inflation pressure as soon as possible. Adjust
the spare tire at the same time. Refer to “Tires” on page 7-
20.NOTE
When inspecting or adjusting the tire pressure, do not
apply excessive force to the valve stem to avoid breakage.

After inspecting or adjusting the tire pressure, always
reinstall the valve cap on the valve stem.
Without the valve cap, dirt or moisture could get into the
valve, resulting in damage to the tire inflation pressure
sensor.

Do not use metal valve caps, which may cause a metal
reaction, resulting in corrosion and damage of the tire
inflation pressure sensors.

Once adjustments have been made, the warning light will
go off after a few minutes of driving.
2. If the tire pressure monitoring system warning light
remains illuminated after you have been driving for about
20 minutes after you adjust the tire inflation pressure, one
or more of the tires may have a puncture. Inspect the tire
and if it has a puncture, have it repaired by an authorized
Mitsubishi Motors dealer as soon as possible.
NOTE
To avoid the risk of damage to the tire inflation pressure
sensors, have any punctured tire repaired by an authorized
Mitsubishi Motors dealer. If the tire repair is not done by
an authorized Mitsubishi Motors dealer, it is not covered
by your warranty.

Do not use an aerosol puncture-repair spray on any tire.
Such a spray could damage the tire inflation pressure sen-
sors. Have any puncture repaired by an authorized
Mitsubishi Motors dealer.
WA R N I N G
!
If the tire pressure monitoring system warning light
illuminates while you are driving, avoid hard brak-
ing, sharp steering maneuvers and high speeds.
Driving with an under-inflated tire adversely affects
vehicle performance and can result in an accident.
CAUTION
!
If a tire has a puncture, replace that tire with the
spare tire. Driving on a punctured tire could lead to
an accident.
The tire pressure monitoring system warning light
may not illuminate immediately in the event of a tire
blowout or rapid leak.

The tire pressure monitoring system may not work normally in
the following circumstances:

A wireless facility or device using the same frequency is
near the vehicle.

Snow or ice is stuck inside the fenders and/or on the
wheels.

The tire inflation pressure sensors’ battery is exhausted.

Wheels other than Mitsubishi Motors genuine wheels are
being used.

Wheels that are not fitted with tire inflation pressure sen-
sors are being used.

Wheels whose ID codes are not memorized by the vehicle
are used.

Compact spare tire is fitted on a road wheel.

A window tint that affects the radio wave signals is
installed.NOTE
Tire inflation pressures vary with the ambient tempera-
ture. If the vehicle is subjected to large variations in ambi-
ent temperature, the tire inflation pressures may be under-
inflated (causing the warning light to come on) when the
ambient temperature is relatively low. If the warning light
comes on, adjust the tire inflation pressure.
Whenever the tires and wheels are replaced with
new ones
N00532900036
If you use new wheels with new tire inflation pressure sensors,
their ID codes must be programmed into the tire pressure mon-
itoring system. Have tire and wheel replacement performed by
an authorized Mitsubishi Motors dealer to avoid the risk of
damaging the tire inflation pressure sensors. If the wheel
replacement is not done by an authorized Mitsubishi Motors
dealer, it is not covered by your warranty.
CAUTION
!
The use of non-genuine wheels will prevent the
proper fit of the tire inflation pressure sensors,
resulting air leakage or damage of the sensors.
