Brake pad
lAvoid hard braking situations.
New brakes need to be broken-in by
moderate use for the first 200 km (124 miles).
l The disc brakes are provided with a
warning device which emits a shrieking
metallic sound while braking if the brake pads have reached their wear limit. Ifyou hear this sound, have the brake padsreplaced immediately.
WARNINGl Driving with worn brake pads will make
it harder to stop, and can cause an acci-
dent.Hill start assist*
E00628000155
The hill start assist makes it easy to start offon a steep uphill slope by preventing the ve-
hicle from moving backwards. It keeps the
braking force for about 2 seconds when you move your foot from the brake pedal to the
accelerator pedal.
CAUTIONl Do not overly rely on the hill start assist to
prevent backwards movement of the vehicle. Under certain circumstances, even when hill
start assist is activated, the vehicle may
move backwards if the brake pedal is not sufficiently depressed, if the vehicle is heav-
ily loaded, or if the road is very steep or slip- pery.
l The hill start assist is not designed to keep
the vehicle stopped in place on uphill slopes for more than 2 seconds.
l When facing uphill, do not rely on using the
hill start assist to maintain a stopped position as an alternative to depressing the brake ped-
al.
Doing so could result in an accident.
l Do not perform the following operation
while the hill start assist is operating.
[Except for vehicles equipped with keyless operation system]
Turn the ignition switch to the “LOCK” or
“ACC” position.
[Vehicles equipped with keyless operation
system]
Put the operation mode in OFF or ACC.
The hill start assist could stop operating, which could result in an accident.To operate
E00628100374

place the selector lever into the “D” po- sition.NOTEl When reversing on an uphill slope, place the
gearshift lever or the selector lever into the
“R” position.
3. Release the brake pedal and the hill start
assist will maintain the braking force ap-
plied while stopping for approximately 2 seconds.
4. Depress the accelerator pedal and the
hill start assist gradually will decrease the braking force as the vehicle startsmoving.
NOTEl The hill start assist is activated when all of
the following conditions are met.
• The engine is running.
(The hill start assist will not be activated

play varies depending on the vehicle model.CAUTIONl If the warning is displayed, the hill start as-
sist will not operate. Start off carefully.CAUTIONl Park your vehicle in a safe place and stop
the engine.
Restart the engine and check whether the warning display went out, in which case the
hill start assist is again working normally.
If the warning remains displayed or reap-
pears frequently, it is not necessary to stop the vehicle immediately, but the vehicle
should be inspected at a MITSUBISHI
MOTORS Authorized Service Point as soon
as possible.Brake assist system
E00627001588
The brake assist system is a device assistingdrivers who cannot depress the brake pedalfirmly when it is necessary to do so (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.
Brake assist system

OGAE14E1Starting and driving6

CAUTIONlThe brake assist system is not a device de-
signed to exercise braking force greater than its capacity. Make sure to always keep a suf-
ficient distance between vehicles in front of
you without relying too much on the brake
assist system.NOTEl 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.
l The brake assist system may become opera-
tional when the brake pedal is fully de- pressed even if it has not been depressed suddenly. [Except for vehicles equipped
with Active Stability Control (ASC)]
l When the brake assist system is in use, you
may feel as if the depressed brake pedal issoft, the pedal moves in small motions inconjunction with the sound of the ABS oper- ation, or the vehicle body and the steering
wheel vibrate. This occurs when the brake
assist system is operating normally and does not indicate faulty operation. Continue to
firmly depress the brake pedal.
l You may hear an operation noise when the
brake pedal is suddenly or fully depressed
while stationary. This does not indicate a malfunction and the brake assist system is
operating normally.NOTEl When the ABS warning lamp/display or on-
ly ASC warning display illuminate, the
brake assist system in not functioning. [Ve- hicles equipped with Active Stability Con-
trol (ASC)]Emergency stop signal
system E00626000018
This is a device that reduces the possibility ofrear end collisions by the rapid and automatic blinking of the hazard warning lamps to alert
vehicles approaching from behind during sudden braking. When the emergency stop
signal system operates, the hazard warning indication lamp in the instrument cluster
blinks rapidly at the same time.
CAUTIONl If the ABS warning or ASC warning is dis-
played, the emergency stop signal system may not operate.
Refer to “ABS warning lamp/display” on
page 6-47.
Refer to “ASC warning display” on page 6-52.NOTEl [Activating condition for the emergency stop
signal system]
It activates when all of the following condi-
tions are met.
• The vehicle speed is approximately
55 km/h (34 mph) or higher.
• The brake pedal has been depressed, and
the system judges that it was sudden brak- ing from the vehicle deceleration and theoperating condition of the anti-lock brake
system (ABS).
[Deactivating condition for the emergency
stop signal system]
It deactivates when one of the following conditions is met.
• The brake pedal is released.
• The hazard warning flasher switch is
pressed.
• The system judges that it was not sudden
braking from the vehicle deceleration and
the operating condition of the anti-lock
brake system (ABS).Anti-lock brake system
(ABS) E00607101046
The anti-lock brake system (ABS) helps pre-vent the wheels from locking up when brak-
ing. This helps maintain vehicle drivability and steering wheel handling.

Driving hints
lAlways keep a safe distance from the ve-
hicle in front of you. Even if your vehi- cle is equipped with ABS, leave a great-
er braking distance when: • Driving on gravel or snow-covered
roads.
• Driving with tyre chains installed.
• Driving on uneven road surfaces.
l Operation of ABS is not restricted to sit-
uations where brakes are applied sud-
denly. This system may also prevent the
wheels from locking when you drive over manholes, steel roadwork plates, road markings, or any uneven road sur-
face.
l When the ABS is activated, you may
feel the brake pedal pulsation and the vi- brations of the vehicle body and steering
wheel. It may also feel as if the pedal re-
sists being pressed.
In this situation, simply hold the brake pedal down firmly. Do not
pump the brake, which will result in reduced braking performance.
l An operation noise is emitted from the
engine compartment or you can feel a shock from the brake pedal when start
driving immediately after starting the en-
gine. These are normal sounds or opera- tions that the ABS makes when perform-ing a self-check. It does not indicate a
malfunction.
l The ABS can be used after the vehicle
has reached a speed over approximately 10 km/h (6 mph). It stops working when the vehicle slows below approximately5 km/h (3 mph).CAUTIONl The ABS cannot prevent accidents. It is your
responsibility to take safety precautions and to drive carefully.
l To prevent failure of the ABS, be sure all 4
wheels and tyres are the same size and the same type.
l Do not install any aftermarket limited-slip
differential (LSD) on your vehicle. The ABS may stop functioning properly.ABS warning lamp/display

If there is a malfunction in the system, the
ABS warning lamp will come on and the
warning display will appear on the informa- tion screen in the multi-information display.
Under normal conditions, the ABS warning
lamp only comes on when the ignition switch
is turned to the “ON” position or the opera- tion mode is put in ON and goes off a few
seconds later.

CAUTIONlAny of the following indicates that the ABS
is not functioning and only the standard brake system is working. (The standardbrake system is functioning normally.) If
this happens, we recommend you to have
your vehicle inspected as soon as possible.
• When the ignition switch is turned to the
“ON” position or the operation mode is put in ON, the warning lamp does notcome on or it remains on and does not go
off.
• The warning lamp comes on while driving
• The warning display appears while driv-
ingIf the warning lamp/display il-
luminate while driving
E00607301295
If only the ABS warning lamp/
display illuminate
Avoid hard braking and high-speed driving.
Stop the vehicle in a safe place.
Restart the engine and check to see whether the lamp goes out after a few minutes driv-
ing; if it then remains off during driving, there is no problem.
However, if the warning lamp/display do not
disappear, or if they come on again when the
vehicle is driven, we recommend you to have the vehicle checked.
If the ABS warning lamp/
display and brake warning
lamp/display illuminate at the same timeWarning lampWarning display type 1Warning display type2
The ABS 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 we rec-
ommend you to have it checked.NOTEl The ABS warning lamp and brake warning
lamp illuminate at the same time and the
warning displays appear alternately on the information screen in the multi-informationdisplay.After driving on icy roads
E00618800150
After driving on snow or icy roads, remove
any snow and ice which may have accumula-
ted around the wheels. On vehicles that have
an ABS, be careful not to damage the wheel
speed sensors (A) or the cables located at each wheel.

Active stability control
(ASC)* E00616700331
The Active Stability Control (ASC) takes
overall control of the anti-lock brake system, traction control function and stability control
function to help maintain the vehicle’s con-
trol and traction. Please read this section in conjunction with the page on the anti-lock
brake system, traction control function and stability control function.

Anti-lock brake system (ABS) ® p. 6-46
Traction control function ® p. 6-50
Stability control function ® p. 6-50CAUTIONl 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 lim-
its and cannot help you to maintain traction and control of the vehicle in all circumstan- ces. Reckless driving may lead to accidents. It is the driver’s responsibility to drive care-
fully. This means taking into account the traffic, road and environmental conditions.
l Be sure to use the same specified type and
size of tyre on all 4 wheels. Otherwise, the ASC may not work properly.CAUTIONl Do not install any aftermarket limited-slip
differential (LSD) on your vehicle. The ASC
may stop functioning properly.NOTEl An operation noise may be emitted from the
engine compartment in the following situa-
tions. The sound is associated 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 malfunc-
tion.
• When the ignition switch is turned to the
“ON” position or the operation mode is
put in ON.
• When the vehicle is driven for a while af-
ter the engine is turned on.
l When the ASC is activated, 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 operating
normally. It does not indicate a malfunction.
l When the anti-lock brake system warning
lamp is illuminated, the ASC is not active.Traction control function
E00619000087
On slippery surfaces, the traction control
function prevents the drive wheels from spin-
ning excessive, thus helping the vehicle to start moving from a stopped condition. It also
provides sufficient driving force and steering performance as the vehicle turns while press-
ing the acceleration pedal.
CAUTIONl When driving a vehicle on a snowy or icy
road, be sure to install snow tyres and drive
the vehicle at moderate speeds.Stability control function
E00619100017
The stability control function is designed to
help the driver maintain control of the vehicle
on slippery roads or during rapid steering ma-
noeuvres. It works by controlling the engine output and brake on each wheel.
NOTEl The stability control function operates at
speeds of about 15 km/h (9 mph) or higher.

This display/incicator will turn on when the ASC is turned off with the “ASC OFF” switch.NOTEl The combination of items shown on the dis-
play varies depending on the vehicle model.CAUTIONl When display/indicator blinks, ASC is
operating, which means that the road is slip- pery or that your vehicle’s wheels are begin-
ning to slip. If this happens, drive slower with less accelerator input.
l If the temperature in the braking system con-
tinues to increase due to continuous brake
control on a slippery road surface, the
dis-
play/indicator will blink. To prevent the
brake system from overheating, the brake
control of the traction control function will
be temporarily suspended.
