3 Limited-slip differential
(if so equipped)
N00517400085
A limited-slip differential is applied for rear wheel differential.
The features of this limited-slip differential are described
below:
Just as with a conventional differential, the wheel on one side
is allowed to turn at a different speed from the wheel on the
other side when the vehicle is cornering. The difference
between the limited-slip differential and a conventional differ-
ential is that if the wheel on one side of the vehicle loses trac-
tion, a greater amount of torque is applied to the wheel on the
other side to improve traction.NOTE
Even if there is a difference in the amount of traction the
wheels can get, if both of them are spinning, the limited-
slip differential will not be effective.
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.
CAUTION
!
Never start the engine while one of the front or rear
wheels is jacked up and the others in contact with
the ground; doing so may cause the vehicle to jump
forward.
Continuously attempting to extract the vehicle from
snow, mud, etc. while using high engine rpm may
damage the limited-slip differential.
Using a compact spare wheel will adversely affect
the limited-slip differential; replace the compact
spare wheel with a standard size wheel as soon as
possible.
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.

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.

3 Hill start assist (for vehicles equipped with
Twin Clutch SST)
N00562600061
The hill start assist makes it easy to start off on a steep uphill
slope by preventing the vehicle 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.
To operate
N00562700088
1. Stop the vehicle completely using the brake pedal.
2. Release the brake pedal and the hill start assist will main-
tain the braking force applied while stopping for approxi-
mately 2 seconds.
3. Depress the accelerator pedal and the hill start assist grad-
ually will decrease the braking force as the vehicle starts
moving.NOTE
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 while the
engine is starting or immediately after the engine is
started.)
• The gearshift lever is in any position other than “P”
(PARK) or “N” (NEUTRAL).
• The vehicle is completely stationary, with the brake
pedal depressed.
• The parking brake is released.

The hill start assist will not operate if the accelerator pedal
is depressed before the brake pedal is released.

The hill start assist also operates when reversing on an
uphill slope.
CAUTION
!
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 acti-
vated, the vehicle may move backwards if the brake
pedal is not sufficiently depressed, if the vehicle is
heavily loaded, or if the road is very steep or slip-
pery.
The hill start assist is not designed to keep the vehi-
cle 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 turn the ignition switch to the “LOCK” or
“ACC” position while the hill start assist is operat-
ing. The hill start assist could stop operating, which
could result in an accident.

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 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.
• 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
• The warning display appears while driving

3 Power steering system
N00518000310
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, but
you will notice it takes much more effort to steer. If this hap-
pens, have your vehicle inspected at an authorized Mitsubishi
Motors dealer or a repair facility of your choice.

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.

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.
