If the power brake unit or either of the two brake hydraulic systems stops working prop-erly, the rest of the brake system will still work, but the vehicle will not slow down as quickly.You will know this ha
s happened if you find
you need to press the brake down farther, or harder when slowing down or stopping, or ifthe brake warning light and the warning dis- play in the multi-information display comes on. Have the brake system repaired at an authorized Mitsubishi Motors dealer or a repair facility of y
our choice immediately.

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.
N00562601114
The hill start assist makes it easy to start offon a steep uphill slope by preventing the vehicle from moving backwards. It keeps the brakes applied for about 2 seconds when youmove your foot from the brake pedal to the accelerator pedal.
N00562701115
1. Stop the vehicle completely using the brake pedal.
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 theengine while driving, the power brake booster will stop wo
rking and your brakes
will not work as well. If the power assist is lost or if either brake hydraulic system stop
s working properly,
take your vehicle
to an authorized
Mitsubishi Motors dealer
or a repair facil-
ity of your choice immediately.
Brake pad wear alarm
WA R N I N G Driving with worn brake pads will make it harder to stop, and can cause an accident.
Hill start assist
CAUTION Do not overly rely on the hill start assist to prevent backwards movement of the vehicle.Under certain circumstan
ces, even when hill
start assist is activated, the vehicle may move backwards if the brake pedal is not suf- ficiently depressed, if the vehicle is heavilyloaded, or if the road is very steep or slip- pery.  The hill start assist is
not designed to keep
the vehicle stopped in place on uphill slopes for more than 2 seconds. When facing uphill, do not rely on using the hill start assist to
maintain a stopped position
as an alternative to depressing the brake pedal. Doing so could cause an accident. Do not perform the following operation while the hill start assist is operating.[Except for vehicles equipped with the F. A . S . T. - k e y ] Turn the ignition switch to the “OFF” or“ACC” position. [Vehicles equipped with the F.A.S.T.-key] Put the operation mode
in OFF or ACC. The
hill start assist coul
d stop operating, which
could result in an accident.

Anti-lock braking system
Features and controls 5-47
5
If the brake pedal is depressed suddenly, the brakes will be applied with more force thanusual.
N00517900338
The anti-lock braking system helps prevent the wheels from locking up when braking. This helps maintain vehicle drivability andsteering wheel handling.  When using the anti-lock brakes (sudden braking), steering 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 vehi- cle is equipped with
the anti-lock braking
system, leave a greater braking distance when: • Driving on gravel or snow-coveredroads. • Driving on uneven road surfaces.  Operation of anti-lock braking system is not restricted
situations where brakes are
applied suddenly. This system may also prevent the wheels from locking whenyou 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 vibrat-ing and hear a unique sound. It may also feel as if the pedal
resists being pressed.
In this situation, si
mply hold the brake
pedal down firmly. Do not pump the brake, which will result in reduced braking performance.
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 be
tween your vehicle and
a vehicle in front of
you without relying too
much on the brake assist system.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.  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 smallmotions in conjunction with the operation noise, or the vehicle body and the steering wheel vibrate. This occurs when the brakeassist system is ope
rating normally and does
not indicate faulty
operation. Continue to
depress the brake pedal.  When the anti-lock brake system warning light is illuminated, the brake assist system is not functioning.
Anti-lock braking system Driving hints
CAUTION The anti-lock braking system cannot prevent accidents. It is your
responsibility to take
safety precautions a
nd 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.NOTE
 You may feel the operating sound or vibra- tion from under the body when driving immediately after starting the engine. This is a normal result the anti-lock braking systemmakes when performing a self-check. It does not indicate a problem.  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 3mph (5 km/h).

N00568400074
The power steering system operates while the engine is running. It helps reduce the effort needed to turn the steering wheel. The power steering system has mechanicalsteering capability in ca
se the power assist is
lost. If the power assist is lost for some rea- son, you will still be ab
le to steer your vehi-
cle, but you will notice it takes much more effort to steer. If this happens, have your vehi- cle inspected at an authorized MitsubishiMotors dealer or a repair facility of your choice.
If there is a malfunction in the system, the warning light will come on. Under normal conditions
, the warning lamp
comes on when the ignition switch is turnedto the “ON” position or the operation mode is put in ON, and goes off after the engine has started.

WA R N I N G Do not stop the engine while the vehicle is moving. Stopping the engine would makethe steering wheel extremely hard to turn,possibly resulting
in an ac
cident.
NOTE
During repeated full-lock turning of the steering wheel (for example, while you are manoeuvring the vehicl
e into a parking
space), a protection
function may be acti-
vated to prevent overheating of the power steering system. This f
unction will make the
steering wheel graduall
y harder to turn. In
this event, limit your turning of the steering wheel for a while. When the system hascooled down, the steeri
ng effort will return
to normal.  If you turn the steering wheel while the vehi- cle is stationary with
the headlights on, the
headlights may become
dim. This behavior
is not abnormal. The he
adlights will return to
their original brightne
ss after a short while.

On slippery surfaces, the traction control function prevents the drive wheels from spin-
ning excessive, thus helping the vehicle to start moving from a stopp
ed condition.
It also
provides sufficient driv
ing force and steering
performance as the vehicle turns while press- ing the acceleration pedal.
N00559300051
The skid control function is designed to helpthe driver maintain control of the vehicle onslippery roads or during rapid steering maneuvers. It works by controlling the engine output and the brake on each wheel.

Active stability control (ASC)
CAUTION Do not over-rely on the ASC. Even the ASC cannot prevent the natural laws of physicsfrom acting on the vehicle. This system, like any other system, has
limits and cannot help
you to maintain traction and control of thevehicle in all circumstances. Reckless driv- ing can lead to accidents. It is the driver’s responsibillty to drive carefully, This meanstaking into account the tr
affic, road and envi-
ronmental 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 differential (LSD) on your vehicle. The ASCmay stop functioning properly.NOTE
 An operating sound or vibration may be emitted from under the body in the followingsituations. The sound or
vibration is associ-
ated with checking th
e operations of the
ASC. At this time, you may feel a shockfrom under the body and the brake pedal if you depress it. These do
not indicate a mal-
function. • When the ignition switch is turned to the “ON” position or the operation mode is putin ON. • When the vehicle is driven for a while after the engine is turned on.
 When the ASC is acti
vated, you may feel a
vibration in the vehicle body or hear a whin- ing sound from the engine compartment. This indicates that the system is operatingnormally. It does not i
ndicate a malfunction.
 When the anti-lock braking system warning light is illuminated, the ASC is not active.

ASC OFF indicator This indicator will turn on when the ASC is turned off with the “ASCOFF” switch.
CAUTION When indicator blinks, ASC is operating, which means that the road is slippery or that your vehicle’s wheels are beginning to slip. If this happens, drive slower with less accel-erator input.NOTE
NOTE
 The indicator may turn on when you start the engine. This means
that the battery volt-
age momentarily dropped when the enginewas started. It does not
indicate
a malfunc-
tion, provided that the display goes out immediately.  When a compact spare tire has been put on your vehicle, the grippi
ng ability of the tire
will be lower, making it more likely that the indicator will blink.
