Limited-slip differential*
E00606900037
A limited-slip differential is applied
for the rear
wheel differential only. 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 differential 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
l 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. CAUTION
l
Never start the engine
while
one of the
rear wheels is jacked up and the other in
contact with the ground; doing so may
cause the vehicle to jump forward.
l When attempting to extract the vehicle
from snow, mud, etc., and the engine is
run continuously at high speed, the limi-
ted-slip differential will be adversely af-
fected. Braking
E00607001494
All the parts
of the

brake system are critical to safe-
ty. We recommend you to have the vehicle
checked at regular intervals according to the serv-
ice booklet. CAUTION
l
Avoid driving habits that
cause
heavy
braking 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 cir-
cuits. And your vehicle is equipped with power
brakes. If one brake circuit fails, the other is availa-
ble to stop the vehicle. If you should lose the pow-
er 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 re-
sists being depressed, keep depressing the brake ped-
al down harder and further than usual; stop driving
as soon as possible and have the brake system re-
paired. WARNING
l Do not turn off the
engine while your ve-
hicle is in motion. If you turn off the en-
gine while driving, the power assistance
for the braking system will stop working
and your brakes will not work effectively. WARNING
l If the power assist is
lost or if either
brake hydraulic system stops working
properly, have your vehicle checked im-
mediately.
Warning lamp
The brake warning lamp illuminates

to indicate a
fault in the braking system. Refer to “Brake warn-
ing lamp” on page 3-08.
When brakes are wet
Check the brake system while driving at a low
speed immediately after starting, especially when
the brakes are wet, to confirm they work normally.
A film of water can be formed on the brake discs
or brake drums and prevent normal braking after
driving 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 depress-
ing the brake pedal.
When driving downhill
It is important to take advantage of the engine brak-
ing by shifting to a lower shift position while driv-
ing on steep downhill roads in order to prevent the
brakes from overheating. Starting and driving

If the warning lamp illuminates while
driving
E00607300663
If only the ABS warning lamp illuminates l 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 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 The ABS warning lamp can illuminate if the
battery voltage is insufficient when the en-
gine is started. In this case, it does not indi-
cate an ABS fault.
Charge the battery by allowing the engine to
idle for a while.
If the battery has been charged but the ABS
warning lamp continues to illuminate or illu-
minates intermittently, have the vehicle in-
spected.
If the ABS warning lamp and brake warning
lamp illuminate at the same time l 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 contact a
MITSUBISHI MOTORS Authorized Service
Point. NOTE
l Immediately
after the vehicle starts
moving
after engine start up, a whining sound of a mo-
tor will be heard from the engine compart-
ment. If the brake pedal is depressed at that
moment, you can feel the brake pedal pulsat-
ing.
This pulsation is due to the self-diagnosis op-
eration of the ABS and does not indicate a
malfunction.
l 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.
Front
Rear l
The ABS becomes operative after the vehicle
has accelerated to a
speed

in excess of approx-
imately 10 km/h (6 mph). It stops operating
when the vehicle decelerates to a speed be-
low approximately 7 km/h (4 mph). Starting and driving

Power steering system
E00607400260
The power steering system operates
while the en-
gine is running. 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 pow-
er assist is lost for some reason, you will still be
able to steer your vehicle. If the power assist is
lost, you will notice it takes much more effort to
steer and that there is much more “free play” in the
steering wheel. If this happens, take your vehicle to
an authorized MITSUBISHI MOTORS dealer. WARNING
l 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 accident. CAUTION
l
Do not leave the steering
wheel turned all
the way in one direction. This can cause
damage to the power steering system. Active Stability & Traction
Control (ASTC)* E00616700344
The active stability & traction

control (ASTC)
takes overall control of the anti-lock brake system,
traction control function and Active Stability Con-
trol function to help maintain the vehicle’s control
and traction. Please read this section in conjunction
with the page on the anti-lock brake system, trac-
tion control function and Active Stability Control
function.

Anti-lock brake system (ABS) ® p. 4-44
Active Traction Control function ® p. 4-48
Active Stability Control function ® p. 4-48 CAUTION
l
Do not over-rely on
the
ASTC. This sys-
tem, like any other system, has limits and
cannot help you to maintain traction and
control of the vehicle in all circumstan-
ces. Reckless driving may lead to acci-
dents. Always drive carefully, taking into
account the traffic, road and environmen-
tal conditions.
l Be sure to use the same specified type and
size of tyre on all 4 wheels. Otherwise, the
ASTC may not work correctly.
NOTE l After
your vehicle is driven

a short distance
after starting the engine, a click is heard from
the engine compartment; however, this is on-
ly the sound of ASTC being checked. l
Some
vibration will be
felt
in the vehicle
body and a whining sound of a motor will be
heard from the engine compartment when
the ASTC functions. This is a normal result
of the ASTC operation, and does not indicate
a malfunction.
l The ASTC does not operate while the ABS
warning lamp is illuminated.
l On vehicles with the rear differential lock,
the ASTC and ABS functions are suspended
while the rear differential lock is activated.
ASTC indication lamp, ASTC OFF indica-
tion lamp and ABS warning lamp are illumi-
nated while these functions are suspended. It
does not indicate a problem. When the rear
differential lock is disengaged, these lamps
go out and function again.
Refer to “ABS warning lamp” on page 4-45,
“ASTC indication lamp, ASTC OFF indica-
tion lamp” on page 4-48.
Driving hints E00616800039
When extricating the vehicle from mud, sand or
fresh snow, you may find

that operation of the
ASTC prevents the engine speed from increasing
in response to depression of the accelerator pedal.
If this happens and the vehicle remains stuck as a
result, deactivate the ASC function by pressing the
“ASC OFF” switch. The vehicle will then be easier
to extricate. (Brake control of the ATC function is
still working to prevent wheel spins when the ASC
function is deactivated by pressing the “ASC OFF”
switch.) Starting and driving

indication lamp is illuminated when the Active
Stability Control function is OFF. CAUTION
l
When indication lamp blinks, Active
Stability Control function or active
trac-
tion control function is operating, which
means that the road is slippery or that
your vehicle’s wheels are slipping exces-
sively. If this happens, drive slower with
less accelerator input.
l If an abnormal condition occurs in the sys-
tem while driving, the indication lamp
will illuminate.
In these cases, follow these procedures: CAUTION
• If the temperature in the braking sys-
tem continues to increase

due to con-
tinuous brake control on a slippery
road surface, the indication lamp
will illuminate, and operation of

the
Active Stability Control function and
active traction control function will be
suspended to protect the brake sys-
tem. (Normal operation of the vehicle
will not be affected.) Park your vehi-
cle in a safe place. When the tempera-
ture in the braking system has come
down, the indication lamp will go
off and the Active Stability

Control
function and active traction control
function will start operating again.
• If the indication lamp does not go
out even though the above

procedure
is followed, there could be a problem
in the system.
Stop the engine and start the engine
again and check whether the indi-
cation lamp goes out. If

the indication
lamp goes out, there is no abnormal
condition.
If the indication lamp illuminates
even after your vehicle is

driven a
short distance after restarting the en-
gine, we recommend you to have your
vehicle checked as soon as possible. CAUTION
l
If the vehicle is
towed
with the ignition
switch in the “ON” position and only the
front wheels or only the rear wheels
raised off the ground, the ASTC may op-
erate, resulting in an accident. When tow-
ing the vehicle with the front wheels
raised, keep the ignition switch in the
“LOCK” or “ACC” position. When tow-
ing the vehicle with the rear wheels
raised, keep the ignition switch in the
“ACC” position.

E00800502112
If the engine cannot be
started because the battery
is weak or dead, the battery from another vehicle
can be used with jumper cables to start the engine. WARNING
l To start the engine
using
jumper cables
connected from another vehicle, perform
the correct procedures according to the in-
struction manual. Incorrect procedures
could result in a fire or explosion or dam-
age to the vehicles.
1. Get the vehicles close enough so the jumper
cables can
reach, but

be sure the vehicles
aren’t touching each other.
If they are, it could cause a ground connec-
tion you don’t want. The vehicle will not
start, and the bad grounding could damage
the electrical systems. CAUTION
l
Check the other vehicle.
It
must have a 12-
volt battery.
If the other system isn’t 12-volt, shorting
can damage both vehicles.
2. You could be injured if the vehicles move.
Set the
parking brake

firmly on each vehicle.
Put an automatic transmission in “P”
(PARK) or a manual transmission in “N”
(Neutral). Turn off the ignition switch. WARNING
l Turn off the ignition on
both vehicles be-
forehand.
Make sure that the cables or your clothes
cannot be caught by the fan or drive belt.
Personal injury could result.
NOTE l Turn
off all lamps, heater

and other electrical
loads. This will avoid sparks and help save
both batteries.
3. Make sure battery electrolyte is at the proper level.
Refer to “Battery” on page 8-10. WARNING
l If electrolyte fluid is
not
visible, or ap-
pears to be frozen, Do Not Attempt Jump
Starting!
A battery might rupture or explode if the
temperature is below the freezing point
or if it is not filled to the proper level.
4. Connect one end of one jumper cable to the

corrosion before use.
6. Start the engine in the vehicle which has the
booster battery,
let the

engine idle a few mi-
nutes, then start the engine in the vehicle
with the discharged battery. CAUTION
l
Keep the engine of the
vehicle giving assis-
tance running.
7. After the engine is started, disconnect the ca-
bles in the reverse order. WARNING
l Charging the battery while it
is installed
in the vehicle might cause the battery to
catch fire and explode.
Or damage to the vehicle could result. If
it has to be charged in that condition for
unavoidable reasons, disconnect the vehi-
cle side negative (-) terminal connected to
the battery.
l Keep sparks, cigarettes and flames away
from the battery because the battery may
produce an explosion.
l Use adequate ventilation when charging
or using the battery in an enclosed space.
l Remove all the caps before charging the
battery.
l Electrolyte is corrosive diluted sulphuric
acid.
