3 Service brake
N00517500262
Brake pedalOveruse of the brake can cause poor brake response and pre-
mature wear of the brake pads and linings.
When driving down a long or steep hill, use engine braking by
downshifting.
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.
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 and lining 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.

3-138 Features and controls
3Brake assist system
N00567300050
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.
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.
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.

3 Anti-lock braking system
N00517900282
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.
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).
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.

Anti-lock braking system warning light/display
N00531600616
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
!
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.
• When the ignition switch is in the “ON” position,
the warning light does not come on or it remains
on and does not go off
• The warning light comes on while driving

play comes on
Avoid hard braking and high-speed driving. Stop the vehi-
cle in a safe place.
Test the system by restarting the engine and driving at a
speed of about 12 mph (20 km/h) or higher.
If the warning light/display then remain off during driv-
ing, there is no problem.
However, if the warning light/display do not disappear, or
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.

and brake warning light/display come on at the same
timeWarning light

Warning display type 1

Warning display type 2

The anti-lock braking system and brake force distribution func-
tion may not work, so hard braking could make the vehicle
unstable.
Avoid hard braking and high-speed driving. Stop the vehicle in
a safe place and contact an authorized Mitsubishi Motors
dealer or repair facility of your choice.NOTE
The anti-lock braking system warning light and brake
warning light illuminate at the same time and the warning
displays appear alternately on the information screen in
the multi-information display.

3 Power steering system
N00518000277
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 Mit-
subishi Motors dealer or a repair facility of your choice.
Hydraulic power steering system (HPS)
(if so
equipped)
N00547100049
The hydraulic power steering system (HPS) uses a hydraulic
pressure pump to assist the turning of the steering wheel.Electric power steering system (EPS)
(if so
equipped)
N00547200040
The electric power steering system (EPS) uses an electric
motor to assist the turning of the steering wheel.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 action 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 behaviour is not abnormal. The headlights will
return to their original brightness after a short while.
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.

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.
Traction control function
N00559200047
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
N00546800023
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.
CAUTION
!
When driving a vehicle on a snowy or icy road, be
sure to install snow tires and drive the vehicle at
moderate speeds.
