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.

display/indicator will turn on.
Warning display
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).
Anti-lock braking system warning light/display

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
!
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 the warning light/display comes on while driv-
ing
N00531700545
If only the anti-lock braking system warning light/dis-
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.
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 Active stability control (ASC)
N00559100091
The active stability control (ASC) takes overall control of the
anti-lock braking system, traction control function and skid
control function to help maintain the vehicle’s control and trac-
tion. Please read this section in conjunction with the page on
the anti-lock braking system, traction control function and skid
control function.
Anti-lock braking system → P. 3 - 1 4 3
Traction control function → P. 3 - 1 5 0
Skid control function → P. 3 - 1 5 0
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.
CAUTION
!
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
limits and cannot help you to maintain traction and
control of the vehicle in all circumstances. Reckless
driving can lead to accidents. It is the driver’s
responsibillty to drive carefully, This means taking
into account the traffic, road and environmental
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 differen-
tial (LSD) on your vehicle. The ASC may stop func-
tioning properly.

NOTE
Using the “ASC OFF” switch turns off both the skid con-
trol function and the traction control function.

When moving out of mud, sand or fresh snow, pressing
the accelerator pedal may not allow the engine speed to
increase. In such situations, temporarily turning off ASC
with the “ASC OFF” switch will make it easier to move
out your vehicle.

If you continue to press the “ASC OFF” switch after the
ASC is turned off, the “mistaken operation protection
function” will activate and the ASC will turn back on.
