BrakingE00607002967
All the parts of the brake system are critical
to safety. We recommend you to have the ve- hicle checked at regular intervals according
to the service booklet.CAUTIONl Avoid driving habits that cause heavy brak-
ing and never “ride” the brakes by resting
your foot on the brake pedal while driving.
It causes brake overheating and fade.
Brake system
The service brake is divided into two brake
circuits. And your vehicle is equipped with
power brakes. If one brake circuit fails, the other is available to stop the vehicle. If you
should lose the power assist for some reason, the brakes will still work. In these situations,
even if the brake pedal moves down to the very end of its possible stroke or resists being
depressed, keep depressing the brake pedal
down harder and further than usual; stop
driving as soon as possible and have the brake system repaired.
WARNINGl Do not turn off the Plug-in Hybrid EV
System while your vehicle is in motion. If
you turn off the Plug-in Hybrid EV Sys- tem while driving, the power assistancefor the braking system will stop working
and your brakes will not work effectively.
l If the power assist is lost or if either brake
hydraulic system stops working properly,
have your vehicle checked immediately.
Warning display
The brake warning lamp illuminates to indi-
cate a fault in the braking system. A warning
is also displayed on the multi information display. Refer to “Brake warning lamp and Brake warning display” on pages 6-44, 6-46.
When brakes are wet
Check the brake system while driving at a
low speed immediately after starting, espe- cially when the brakes are wet, to confirmthey work normally.
A film of water can be formed on the brake
discs and prevent normal braking after driv-
ing in heavy rain or through large puddles, or after the vehicle is washed. If this occurs, dry the brakes out by driving slowly while lightly
depressing the brake pedal.
When driving downhillWARNINGl Do not leave any objects near the brake
pedal or let a floor mat slide under it; do- ing so could prevent the full pedal stroke
that would be necessary in an emergency. Make sure that the pedal can be operated freely at all times. Make sure that thefloor mat is securely held in place.CAUTIONl Put the selector lever to “B” position accord-
ing to the grade of a slope or the speed in along downward slope, and use the regenera-
tive brake together.
If you depress the brake pedal and slowing down is repeated frequently, the foot brake
may be overheated and effectiveness may worsen.

7-25OGGE16E1Starting and driving7
CAUTIONlEffectiveness of the regenerative brake be-
comes weak when the drive battery is close
to full charge and loses its effect at the full
charge.
In this case, since the foot brake is effective,
use the foot brake and slow down your vehi-
cle speed beforehand.
The energy usage indicator stops swaying in the charge zone closer to full charge.
Refer to “Energy usage indicator” on page 6-02
In such case, drive at low speed in advance.
And if needed use the foot brake to slow
down the vehicle speed before the vehicle speed increases.
The regenerative brake comes to be effective if the drive battery remaining power is con-
sumed.
Brake pad
l Avoid 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
E00628001237
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.CAUTIONl Do not turn the operation mode in ACC or
OFF while the hill start assist is operating.
The hill start assist could stop operating, which could result in an accident.To operate
E00628101368
1. Stop the vehicle completely using the
brake pedal.
2. Move the selector lever to the “D” posi-
tion.
NOTEl When reversing on an uphill slope, move the
selector lever to 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.

Restart the Plug-in Hybrid EV System and check whether the display/indicator goes
out, in which case the hill start assist is
working normally again.
If they remain displayed or reappear fre- quently, it is not necessary to stop the vehi-cle immediately, but the vehicle should be inspected by a MITSUBISHI MOTORS Au-
thorized Service Point as soon as possible.Brake assist system
E00627001546
The brake assist system is a device assisting drivers 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 thanusual.CAUTIONl The 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.

7-27OGGE16E1Starting and driving7
NOTElWhen 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 depressed suddenly while sta-
tionary. This does not indicate a malfunction
and the brake assist system is operating nor- mally.
l When the anti-lock brake system warning
lamp or the Active Stability Control warning lamp illuminate, the brake assist system is
not functioning.Emergency stop signal
system E00626001060
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 7-29.
Refer to “ASC warning display” on page
7-34.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) E00607102489
Environmental conditions can have an effect
on braking. During sudden braking when there is snow, ice, oil, water etc. on the road
surface, a skid may occur. In this situation, steering control and braking effectiveness is
reduced and the stopping distance is in-
creased. The vehicle may also go into an un- controlled spin.
The ABS helps prevent the wheels from lock-
ing during braking, thus maintaining direc-
tional stability, ensuring controllability and
providing optimum braking force.
Operating hints
l Always maintain the same distance from
the vehicle in front of you as you would for a vehicle not equipped with ABS.
Compared with vehicles not fitted with ABS, your vehicle may require a longer
stopping distance in the following cases: • Driving on gravel or snow-covered
roads.
• Driving with snow traction device
(tyre chains) installed.
• Driving on roads where the road sur-
face is pitted or has other differences in surface height.
Emergency stop signal system
7-28OGGE16E1Starting and driving7
•Driving on bumpy roads or other poor
driving surfaces.
l Operation of ABS is not restricted to sit-
uations where brakes are applied sud- denly. This system may also operate to
prevent wheel lock when you are driving
over manholes, steel road-work plates, or the vehicle is driven over steps or lev-
el differences in the road, road markings,
or other surfaces which are difficult for
the wheels to grip.
l When the ABS is activated, you may
feel the brake pedal pulsation and the vi-
brations of the vehicle body and steering
wheel. You may also hear a characteris-
tic noise. At this time, you may feel as if the pedal attempts to resist being de-pressed.
This is a normal result of the ABS oper- ation, and does not indicate a problem.
If this situation occurs, depress the
brake pedal more firmly in order to operate the ABS. Do not pump the brake. This will result in reduced braking performance.l You will hear the operation sound of the
motor coming from the Plug-in Hybrid EV System compartment immediately
following start off after starting the
Plug-in Hybrid EV System. If the brake pedal is depressed at that moment, you
can feel the brake pedal pulsating.
This pulsation is due to the self-diagno- sis operation of the ABS and does not
indicate a malfunction.
l The ABS will operate after the vehicle
has accelerated to a speed in excess of approximately 10 km/h (6 mph). It stops
operating when the vehicle decelerates
to a speed below about 5 km/h (3 mph).CAUTIONl Even the ABS cannot prevent the natural
laws of physics from acting on the vehicle. Itcannot for instance avoid accidents that may
result from excessive speed on bends or fol- lowing another vehicle too closely or aqua-
planing. It should remain the driver’s task to observe safety precautions to judge speeds and brake applications correctly in such con-
ditions.
l Be sure to use tyres of the same type and
size on 4 wheels.
If tyre types or sizes are mixed, ABS may not function normally.CAUTIONl Never install a limited-slip differential,
which is not MITSUBISHI MOTORS GEN-
UINE parts, as the ABS may not function
normally.

l Avoid hard braking and high-speed driv-
ing. Stop the vehicle in a safe place.
Restart the Plug-in Hybrid EV System and check to see whether the lamp goes
out after a few minutes driving; if it then remains off during driving, there is no
problem.
However, if the lamp does not go out, or if it lights up again when the vehicle is driven, we recommend you to have the
vehicle checked as soon as possible.
l If you start Plug-in Hybrid EV System
when the auxiliary battery voltage is in-
sufficient, ABS warning lamp/display may illuminate, but this is not a failure
of ABS. When the drive battery is charg-
ed, the auxiliary battery is also charged, and the warning lamp/display will go
out. If the warning lamp/display contin- ues illuminating even after the battery is
sufficiently charged or the warning
lamp/display illuminates frequently, have your vehicle inspected by a
MITSUBISHI MOTORS Authorized
Service Point.
If the ABS warning lamp/ display and brake warning

and contact a MITSUBISHI MOTORS Au-
thorized Service Point.
NOTEl The ABS warning lamp and brake warning

After driving on icy roads
E00618800219
After driving on snowy roads, remove any
snow and ice which may have become ad-
hered to the wheel areas.
When doing this, be careful not to damage the wheel speed sensors (A) and cables loca-ted at each wheel on vehicles equipped with an ABS.
Electric power steering
system (EPS) E00629201294
The power steering system operates while thePlug-in Hybrid EV System is operating.
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 rea-
son, you will still be able to steer your vehi-
cle, but you will notice it takes much more
effort to steer. If this happens, have your ve- hicle inspected at a MITSUBISHI MOTORS
Authorized Service Point.WARNINGl Do not stop the Plug-in Hybrid EV Sys-
tem while the vehicle is moving. Stopping the Plug-in Hybrid EV System would
make the steering wheel extremely hard to turn, possibly resulting in an accident.NOTEl 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 activa-
ted 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 steering action will return to normal.NOTEl If you turn the steering wheel while the vehi-
cle is stationary with the headlamps on, the headlamps may become dim. This behaviour
is not abnormal. The headlamps will return to their original brightness after a shortwhile.

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.

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
Plug-in Hybrid EV System compartment in
the following situations. The sound is asso- ciated 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 operation mode is put in ON.
• When the vehicle is driven for a while af-
ter the Plug-in Hybrid EV System 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 Plug-in Hybrid EV Sys- tem 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 ex-
cessive spinning, 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
E00619101098
The stability control function is designed to
help the driver maintain control of the vehicle
