3 Anti-lock braking system
N00517900295
The anti-lock braking system helps prevent the wheels from
locking up when braking. This helps maintain vehicle drivabil-
ity and steering wheel handling.Driving hints

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 pulsation and the vibrations of the vehicle
body and steering wheel. It 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.


An operation noise is emitted from the engine compart-
ment or feel a shock from the brake pedal when start driv-
ing immediately after starting the engine. These are
normal sound or operation that the anti-lock braking sys-
tem makes when performing a self-check. It does not indi-
cate 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).
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 4 wheels and tires are the same size and
the same type.


Do not install any aftermarket limited-slip differen-
tial (LSD) on your vehicle. The anti-lock braking
system may stop functioning properly.

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 3
Traction control function → P. 3 - 1 2 8
Skid control function → P. 3 - 1 2 8
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.

Traction control function
N00559200021
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
N00546800010
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
N00559400166
When the ignition switch is turned to the “ON” position, the
ASC automatically turns ON. If the ASC OFF switch is
pressed to turn OFF the ASC, the indicator in the meter
comes on. Press the switch again to turn ON the ASC.
CAUTION
!

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

For safety reasons, press the ASC OFF switch when
the vehicle is stopped.


Be sure to turn ON the ASC for normal driving.

NOTE

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 the
ASC with the “ASC OFF” switch will make it easier to
move out your vehicle.


By pressing the ASC OFF switch, both the skid control
function and the traction control function are turned OFF.


By pressing down the “ASC OFF” switch for 3 seconds or
longer, you can deactivate the ASC and the braking con-
trol of the AYC.
At this time, the display will appear for a few sec-
onds on the information screen in the multi-information
display.
Then, the previous screen will return and the “!” mark will
come on.
Press the ASC OFF switch again to turn ON the ASC.


If the ASC OFF switch is continuously pressed after the
ASC has been turned OFF or the ASC and the braking
control of AYC have been turned off, an erroneous opera-
tion prevention function operates and the ASC is automat-
ically turned ON.

3 Limited-slip differential
N00517400014
A limited-slip differential is applied for front wheel differen-
tial. The features of this limited-slip differential are described
below:
Just as with a conventional differential, the wheel on one side
is allowed to turn at a different speed from the wheel on the
other side when the vehicle is cornering. The difference
between the limited-slip differential and a conventional differ-
ential is that if the wheel on one side of the vehicle loses trac-
tion, a greater amount of torque is applied to the wheel on the
other side to improve traction.NOTE

Even if there is a difference in the amount of traction the
wheels can get, if both of them are spinning, the limited-
slip differential will not be effective.
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.
CAUTION
!

Never start the engine while one of the front or rear
wheels is jacked up and the other in contact with the
ground; doing so may cause the vehicle to jump for-
ward.


Continuously attempting to extract the vehicle from
snow, mud, etc. while using high engine rpm may
damage the limited-slip differential.


Using a compact spare wheel will adversely affect
the limited-slip differential; replace the compact
spare wheel with a standard size wheel as soon as
possible.
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.

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.
Cruise control
N00518300472
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.
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
!

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

To resume the set speed
N00518900234
If the set speed driving is deactivated by the condition
described in “To deactivate” on page 3-139, you can resume
the previously set speed by pressing the “ACC RES” switch
(C) while driving at a speed of about 25 mph (40 km/h) or
higher.
Under either of the following conditions, however, using the
switch does not allow you to resume the previously set speed.
In these situations, repeat the speed setting procedure:

The “ON OFF” switch is pressed.


The ignition switch is turned OFF.


“CRUISE” indicator light is turned OFF.
Tire pressure monitoring system
N00530200295
The tire pressure monitoring system uses tire inflation pressure
sensors (A) on the wheels to monitor the tire inflation pres-
sures. The system only indicates when a tire is significantly
under-inflated.
WA R N I N G
!

The compact spare wheel does not have a tire infla-
tion pressure sensor.
When the spare tire is used, the tire pressure moni-
toring system will not work properly.
See an authorized Mitsubishi Motors dealer as soon
as possible to replace or repair the original tire.

Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure rec-
ommended by the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or
tire inflation pressure label, you should determine the proper
tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped
with a tire pressure monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or more of your tires is
significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat and can lead to
tire failure.
Under-inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain
correct tire pressure, even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire pressure tell-
tale.
Your vehicle has also been equipped with a TPMS malfunction
indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale.
When the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists.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.BK0105501US.book 144 ページ ２００９年８月１０日　月曜日　午前１０時３２分

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 exhausted.


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.
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
N00532900124
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, any resulting damage or system performance problems
are not covered by your warranty.
CAUTION
!

The use of non-genuine wheels will prevent the
proper fit of the tire inflation pressure sensors,
resulting in air leakage or damage of the sensors.
