Power brakes
N00517600393
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 should 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.
Brake pad wear alarm
N00532500087
The disc brakes have an alarm that makes a metallic squeal
when the brake pads have worn down enough to need service.
If you hear this sound, have the brake pads replaced at an
authorized Mitsubishi Motors dealer or a repair facility of your
choice.
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.
WA R N I N G
!
Driving with worn brake pads will make it harder to
stop, and can cause an accident.

display/indicator will turn on.
Warning display
Brake assist system
N00567300076
The brake assist system is a device assisting drivers who can-
not depress the brake pedal firmly such as in emergency stop
situations and provides greater braking force.
If the brake pedal is depressed suddenly, the brakes will be
applied with more force than usual.
-ASC indicator
CAUTION
!
If the warning is displayed, the hill start assist will
not operate. Start off carefully.
Park your vehicle in a safe place and stop the engine.
Restart the engine and check whether the dis-
play/indicator goes out, in which case the hill start
assist is again working normally.
If they remain displayed or reappear frequently, it is
not necessary to stop the vehicle immediately, but
the vehicle should be inspected by an authorized
Mitsubishi Motors dealer or a repair facility of your
choice as soon as possible.
CAUTION
!
The brake assist system is not a device designed to
exercise braking force greater than its capacity.
Make sure to always keep a sufficient distance
between vehicles in front of you without relying too
much on the brake assist system.

NOTE
After your vehicle is driven a short distance after starting
the engine, you will hear the sound coming from the
engine compartment. 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).

Warning light
Warning display type 1
Warning display type 2
If there is a malfunction in the system, the anti-lock braking
system warning light will come on and the warning display
will appear on the information screen in the multi-information
display.
Under normal conditions, the anti-lock braking system warning
light only comes on when the ignition switch is turned to the
“ON” position and goes off a few seconds later.
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.
Never install a limited-slip differential as the anti-
lock braking system may not function normally.
Please consult an authorized Mitsubishi Motors
dealer.

if they come on again when the vehicle is driven, have the
vehicle checked by an authorized Mitsubishi Motors
dealer or repair facility of your choice as soon as possible.
CAUTION
!
Any of the following warning light/display behavior
indicates that the anti-lock braking system is not
functioning and only the standard brake system is
working. (The standard brake system will still work
properly.) If this happens, take your vehicle to an
authorized Mitsubishi Motors dealer or a repair
facility of your choice as soon as possible.

NOTE
During repeated full-lock turning of the steering wheel
(for example, while you are manoeuvring the vehicle into
a parking space), a protection function may be activated to
prevent overheating of the power steering system. This
function will make the steering wheel gradually harder to
turn. In this event, limit your turning of the steering wheel
for a while. When the system has cooled down, the steer-
ing effort will return to normal.

If you turn the steering wheel while the vehicle is station-
ary with the headlights on, the headlights may become
dim. This behavior is not abnormal. The headlights will
return to their original brightness after a short while.

3 Active stability control (ASC)
N00559100091
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 page on
the anti-lock braking system, traction control function and skid
control function.
Anti-lock braking system → P. 3 - 1 4 3
Traction control function → P. 3 - 1 5 0
Skid control function → P. 3 - 1 5 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
responsibillty 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.

NOTE
The display/indicator may come on when you start the
engine. This means that the battery voltage momentarily
dropped when the engine was started. It does not indicate
a malfunction, provided that the display goes out immedi-
ately.

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 display/indicator will blink.
ASC warning display
N00546600106
If an abnormal condition occurs in the system, the following
display/indicator will turn on.
Warning display type 1
Warning display type 2 NOTE
The combination of items shown on the display varies
depending on the vehicle model.
CAUTION
!
When display/indicator blinks, 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.
If the temperature in the braking system continues
to increase due to continuous brake control on a
slippery road surface, the display/indicator will
blink. To prevent the brake system from overheat-
ing, the brake control of the traction control func-
tion will be temporarily suspended. The engine
control of the traction control function and normal
brake operation will not be affected. Park your vehi-
cle in a safe place. When the temperature in the
braking system has come down, the display/indi-
cator will be turned off and the traction control
function will start operating again.

Tire pressure monitoring system warning
light/display
N00532700122
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 3-166 and take the necessary measures.NOTE
In addition, the warning display is displayed on the infor-
mation screen in the multi-information display.
Ty p e 1
Ty p e 2
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 Mitsub-
ishi 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.

Ty p e 1
Ty p e 2Each 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.
