3 Anti-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.

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.

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.BK0132701US.book 98 ページ ２０１０年１２月６日　月曜日　午後２時３分

CAUTION
!
While the compact spare tire is stowed, the inflation
pressure should be checked at least once a month to
assure that it remains at the recommended inflation
pressure. See the tire and loading information plac-
ard attached to the driver’s door sill.
Refer to “Tire and loading information placard” on
page 9-4.

Driving with an improperly inflated tire can cause
an accident. If you have no choice but to drive with
an under-inflated tire, keep your speed down and
avoid sudden steering or braking, if possible. Inflate
the tire to the correct pressure as soon as possible.
Refer to “Tire inflation pressures” on page 7-23.
The compact spare tire should only be used tempo-
rarily. When the compact spare tire is used, the tire
pressure monitoring system will not work properly.
See an authorized Mitsubishi Motors dealer as soon
as possible to replace or repair the original tire.
After changing the tire and driving the vehicle about
620 miles (1,000 km), retighten the wheel nuts to
make sure that they have not come loose.
If the steering wheel vibrates when driving after
changing the tire, have the tire checked for balance
at your nearest authorized Mitsubishi Motors dealer
or a repair facility of your choice.
Do not mix one type of tire with another or use a dif-
ferent size from the one listed. This would cause
early wear and poor handling.

ones listed, and avoid the combined use of different
types of tires and wheels. Using different size or type
tires and wheels may affect driving safety.
Refer to “Tires and wheels” on page 9-8.
Even if a wheel has the same rim size and offset as
the specified type of wheel, its shape may prevent it
from being fitted correctly. Consult an authorized
Mitsubishi Motors dealer or a repair facility of your
choice before using wheels that you have.
As your vehicle is equipped with a tire pressure
monitoring system, use only Mitsubishi genuine
wheels.
Other wheels do not permit correct installation of
tire inflation pressure sensors and can cause air
leakage and sensor failure, which would not be cov-
ered by your vehicle’s warranty.
See an authorized Mitsubishi Motors dealer when
you replace a tire or wheel.

Snow tires
N00940000362
In some areas of the country, snow tires are required for winter
driving. If snow tires are required in your area, you must
choose snow tires of the same size and type as the original tires
provided with your vehicle. Snow tires should also be installed
on all four wheels. Otherwise your safety and vehicle handling
can be reduced.
Even where laws may permit it, snow tires should not be oper-
ated at sustained speeds over 75 mph (120 km/h).
CAUTION
!
Avoid the combined use of different types of tires.
Using different types of tires can affect vehicle per-
formance and safety.
