3 Active stability control (ASC)
N00559100121
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 pages on
the anti-lock braking system, traction control function and skid
control function.
Anti-lock braking system → P. 3 - 1 2 5
Traction control function → P. 3 - 1 3 0
Skid control function → P. 3 - 1 3 0
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.
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.

3 Service brake
N00517500291
Brake pedalOveruse of the brake can cause poor brake response and pre-
mature wear of the brake pads.
When driving down a long or steep hill, use engine braking by
downshifting.
Power brakes
N00517600380
Your vehicle is equipped with power brakes for more braking
force with minimal brake pedal effort.
Your brakes are designed to operate at full capacity, even if the
power assist is lost.
If the power assist is lost, the effort needed to press the brake
pedal is greater.
If you lose the power assist for some reason, the brakes will
still work.
If the power brake unit or either of the two brake hydraulic sys-
tems stops working properly, the rest of the brake system will
still work, but the vehicle will not slow down as quickly.
You will know this has happened if you find you need to
depress the brake pedal down further, or harder when slowing
down or stopping, or if the brake warning light and the warning
display in the multi-information display come on.
WA R N I N G
!
Do not leave any objects near the brake pedal or let
a floor mat slide under it; doing so could prevent the
full pedal stroke that would be necessary in an emer-
gency. Make sure that the pedal can be operated
freely at all times. Make sure the floor mat is
securely held in place.
CAUTION
!
It is important not to drive the vehicle with your foot
resting on the brake pedal when braking is not
required. This practice can result in very high brake
temperatures, premature pad wear, and possible
damage to the brakes.
WA R N I N G
!
Never coast downhill with the engine OFF. Keep the
engine running whenever your vehicle is in motion.
If you turn off the engine while driving, the power
brake booster will stop working and your brakes
will not work as well.
If the power assist is lost or if either brake hydraulic
system stops working properly, take your vehicle to
an authorized Mitsubishi Motors dealer or a repair
facility of your choice immediately.

NOTE
Once the brake assist system is operational, it maintains
great braking force even if the brake pedal is lightly
released.
To stop its operation, completely remove your foot from
the brake pedal.

The brake assist system may become operational when the
brake pedal is fully depressed even if it has not been
depressed suddenly.

When the brake assist system is in use while driving, you
may feel as if the depressed brake pedal is soft, the pedal
moves in small motions in conjunction with the operation
noise, or the vehicle body and the steering wheel vibrate.
This occurs when the brake assist system is operating nor-
mally and does not indicate faulty operation. Continue to
depress the brake pedal.

You may hear an operation noise when the brake pedal is
depressed suddenly while stationary. This does not indi-
cate a malfunction and the brake assist system is operating
normally.
Power steering system
N00518000293
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.
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.

Tire pressure monitoring system warning light /
display
N00554800110
When the ignition switch is turned to the “ON” position, the
tire pressure monitoring system warning light normally illumi-
nates and goes off a few seconds later.
If one or more of the vehicle tires (except for the spare tire) is
significantly under-inflated, the warning light will remain illu-
minated while the ignition switch is in the “ON” position.
Refer to “If the warning light/display illuminates while driv-
ing” on page 3-147 and take the necessary measures.NOTE
In addition, the warning display is displayed on the infor-
mation screen in the multi-information display.
CAUTION
!
If the tire pressure monitoring system warning light
does not illuminate when the ignition switch 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 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.

When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, includ-
ing the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to ensure that
the replacement or alternate tires and wheels allow the TPMS
to continue to function properly.

1. If the tire pressure monitoring system warning light illu-
minates, avoid hard braking, sharp steering maneuvers
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-
19.NOTE
In addition, the warning display is displayed on the infor-
mation screen in the multi-information display.

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 product on any tire.
Such a spray could damage the tire inflation pressure sen-
sors. Have any puncture repaired by an authorized
Mitsubishi Motors dealer.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 sensor’s battery is dead.

Wheels other than Mitsubishi 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/display to come on)
when the ambient temperature is relatively low. If the
warning light/display comes on, adjust the tire inflation
pressure.
WA R N I N G
!
If the warning light/display illuminates while you
are driving, avoid hard braking, 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 warning light/display may not illuminate imme-
diately in the event of a tire blowout or rapid leak.
