2011 MITSUBISHI TRITON engine

WARNING
l When attempting to rock your vehicle out
of a stuck position, be
sure that the area
around the vehicle is clear of people and
physical objects. The rocking motion may
cause the vehicle to suddenly launch for-
ward or backward, causing injury or dam-
age to nearby people or objects.
NOTE l Avoid
sudden braking, acceleration, and

turn-
ing; such operations could result in the vehi-
cle becoming stuck.
l If the vehicle becomes stuck in sandy or mud-
dy roads, it can often be moved a rocking mo-
tion. Move the selector lever rhythmically be-
tween the “D” (DRIVE) and “R” (RE-
VERSE) position (with M/T, between 1 st
and
Reverse), while applying slight pressure to
the accelerator pedal.
l It is recommended to start the vehicle with
parking brake partially, but not completely,
applied by slightly pulling the parking brake
lever.
After the vehicle has become free, do not for-
get to release the parking brake.
l If it is necessary to drive in extremely muddy
conditions, the use of tyre chains is recom-
mended. Because the extent of muddy condi-
tions is difficult to judge and the vehicle
could become bogged down very deeply, op-
eration should be at a low speed. If possible,
get out of the vehicle and check the condi-
tions ahead before proceeding. l
Driving over roads in
coastal
areas or roads
on which anti-skid preparations have been
spread can cause rust on the vehicle; wash
the vehicle thoroughly as soon as possible af-
ter such use.
Climbing sharp grades
Set the transfer shift lever to “4L” position (easy se-
lect 4WD), “4LLc” position (super select 4WD) to
maximize the engine torque. WARNING
l Go
straight
up. Do
not
try to traverse
across a steep slope.
l If you begin to lose traction, ease off the
accelerator pedal and gently turn the
steering wheel alternatively left and right
to regain adequate traction again.
NOTE l Choose
as smooth a slope

as possible with
few stones or other obstacles.
l Before attempting to drive up the slope, walk
up it to confirm that the vehicle can handle
the grade.
Descending sharp grades
Set the transfer shift lever to “4L” position (easy se-
lect 4WD), “4LLc” position (super select 4WD),
use the engine brake (downshifting) and descend
slowly. WARNING
l Avoid snaking down a sharp
grade. De-
scend the grade as straight as possible.
NOTE l When descending a sharp grade, if the brakes
are
applied suddenly because of

an obstacle
encountered, control of the vehicle could be
lost. Before descending the slope, walk down
it and confirm the path.
l Before descending a grade, it is necessary to
choose the appropriate gear. Avoid changing
gears or depressing the clutch while descend-
ing the grade.
l MITSUBISHI MOTORS is not responsible
to the operator for any damage or injury
caused or liability incurred by improper and
negligent operation of a vehicle. All techni-
ques of vehicle operation described herein de-
pend on the skill and experience of the opera-
tor and other participating parties and any de-
viation from the recommended operation in-
structions above is at their own risk.
Turning sharp corners
When turning a sharp corner in “4H” or “4L” posi-
tion (easy select 4WD), “4HLc” or “4LLc” posi-
tion (super select 4WD) at low speed, a slight dif-
ference in steering may be experienced similar to
as if the brakes were applied. This is called tight cor-
ner braking and results from each of the 4 tyres be-
ing at a different distance from the corner.
The phenomenon is peculiar to 4-wheel drive vehi-
cles. If this occurs, either straighten the steering
wheel, or change to rear-wheel drive. Starting and driving

Crossing a stream
4-wheel drive vehicles are
not
necessarily water-
proof. If the electrical circuits become wet, further
operation of the vehicle will be impossible; there-
fore, avoid crossing streams unless absolutely nec-
essary. If crossing a stream is unavoidable, use the
following procedure: 1. Check depths of a stream and geographicalfeatures before attempting to cross a stream
and ford the stream where the water is as shal-
low as practicable.
2. Set the transfer shift lever to “4L” position (easy select 4WD), “4LLc” position (super se-
lect 4WD).
3. Drive slowly at a speed of approximately 5 km/h (3 mph) to avoid splashing too much
water. CAUTION
l
Never cross a stream
where
the water is
deep.
Do not change gears while crossing the
stream.
Frequent crossing of streams can adverse-
ly affect the life span of the vehicle; we rec-
ommend you to take the necessary meas-
ures to prepare, inspect, and repair the ve-
hicle.
After crossing a stream, apply the brakes to be sure
they are functioning
properly. If

the brakes are wet
and not functioning properly, dry them out by driv-
ing slowly while lightly depressing the brake pedal.
Inspect each part of the vehicle carefully. Inspection and maintenance
following rough road operation E00606700048
After operating
the vehicle
in

rough road condi-
tions, be sure to perform the following inspection
and maintenance procedures:
l Check that the vehicle has not been damaged
by rocks, gravel, etc.
l Carefully wash the vehicle with water.
After washing, drive the vehicle slowly
while lightly depressing the brake pedal in or-
der to dry out the brakes. If the brakes still
do not function properly, we recommend you
to have the brakes checked as soon as possible.
l Remove the insects, dried grass, etc. clog-
ging the radiator core.
l After crossing a stream, be sure to have the
following items inspected at a MITSUBISHI
MOTORS Authorized Service Point and take
the necessary measures.
• Check the brake system and, if necessary,have it serviced.
• Check the engine, transmission, transfer, and differential oil or grease level and tur-
bidity. If the oil or grease is milky, it indi-
cates water contamination. Replace it
with new oil or grease.
• Grease the propeller shaft.
• Check the inside of the vehicle. If ingress of water is found, dry the carpet etc.
• Inspect the headlamps. If the headlamp bulb is flooded with water, we recom-
mend you to have it drained. Cautions on handling of 4-wheel
drive vehicles E00606800368
Tyres and wheels
Since the driving torque can
be applied to the 4
wheels, the performance of the vehicle when oper-
ating in 4-wheel drive is greatly affected by the con-
dition of the tyres.

Pay close attention to the tyres.
l Install specified tyres on all wheels. Refer to
“Tyres and wheels” on page 9-18.
l Be sure to fit all 4 tyres and wheels of the
same size and type.
When replacement of any of the tyres or
wheels is necessary, replace all of them.
l All tyres should be rotated whenever the
wear difference between the front and rear
tyres is recognizable.
Good vehicle performance cannot be expected if
there is a difference in wear between tyres. Refer to
“Tyre rotation” on page 8-13. l Check the tyre inflation pressure regularly. Starting and driving
4-41 4

OCRE12E1
Presented by http://mmc-manuals.ru/ \251

CAUTION
l
Always use tyres of the same size, same
type, and same brand, and which have no
wear differences. Using tyres of different
size, type, brands or degree of wear, will
increase the differential oil temperature,
resulting in possible damage to the driv-
ing system. Further, the drive train will
be subjected to excessive loading, possibly
leading to oil leakage, component seizure,
or other serious faults.
Towing
If towing is necessary, we

recommend you to have
it done by your MITSUBISHI MOTORS Author-
ized Service Point or a commercial tow truck service.
In the following cases, transport the vehicle using a
tow truck.
l The engine runs but the vehicle does not
move or abnormal noise is produced.
l Inspection of the vehicle’s underside reveals
that oil or some other fluid is leaking. Only when you cannot receive a towing service
from a MITSUBISHI
MOTORS

Authorized Serv-
ice Point or commercial tow truck service, tow
your vehicle carefully in accordance with the in-
structions given in “Towing” on page 6-20 . CAUTION
l
Be sure to shift the
transfer shift lever to
“2H” position and transport the vehicle
with the driving wheels on a carriage
(Type A, C or D) as illustrated.
Never try to tow with the transfer shift lev-
er in “4H” or “4L” position (easy select
4WD), “4H”, “4HLc” or “4LLc” position
(super select 4WD) and with the front or
rear wheels on the ground (Type A or B)
as illustrated. This could result in dam-
age to the drivetrain, or unstable towing.
If you cannot shift the transfer shift lever
to “2H” position or the transmission is
malfunctioning or damaged, transport
the vehicle with all the wheels on a car-
riage (Type C or D) as illustrated.
Jacking up a 4-wheel drive vehicle WARNING
l Do not crank the
engine
while jacking up
the vehicle.
The tyre on the ground may turn and the
vehicle may roll off the jack.
Clutch operation
Quick or slight clutch engagement

made while the
engine is running at high speed will cause damage
to the clutch and transmission because the tractive
force is very great.
Operate the pedal slowly and positively. Starting and driving

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

Active Stability Control function
E00616900056
The Active Stability Control function
is designed
to improve the vehicle’s stability by restraining its
tendency to slip sideways (for example, when round-
ing a curve in slippery conditions, or when the driv-
er takes rapid steering action to avoid an obstacle).
It works by controlling the engine output and brake
on each wheel.
NOTE
l On vehicles with the rear differential lock,
the Active Stability Control function does
not operate when the rear differential lock is
activated. “ASC OFF” switch
The
Active Stability Control function
is automati-
cally activated when the ignition switch is turned to
the “ON” position. You can deactivate the system
by pressing the “ASC OFF” switch when the vehi-
cle speed is below about 40 km/h (25 mph). To re-
activate the Active Stability Control function, press
the “ASC OFF” switch again. It is strongly recom-
mended that the Active Stability Control function
normally be kept activated.
Type 1
Type 2 NOTE
l If
the vehicle speed increases

to about
120 km/h (74 mph) with the Active Stability
Control function deactivated, the Active Sta-
bility Control function automatically starts op-
erating. To subsequently stop the Active Sta-
bility Control function, stop the vehicle and
press the “ASC OFF” switch again. Active Traction Control function
E00617000025
On slippery surfaces, active
traction

control func-
tion prevents the drive wheels from excessive spin-
ning, thus helping the vehicle to start moving from
a stop. It also provides sufficient driving force and
steering performance as the vehicle turns at acceler-
ated speeds. CAUTION
l
When driving a vehicle
on
a snowy or icy
road, be sure to install snow tyres and
drive the vehicle at moderate speeds.
ASTC indication lamp, ASTC OFF in-
dication lamp E00617100071
The Active Stability Control function and active
traction control function
share the

same indication
lamp.
The indication lamps should illuminate when the ig-
nition switch is turned to the “ON” position and
should go off after a few seconds.
If the indication lamps stay on or do not illuminate
when the ignition switch is turned to the “ON” po-
sition, we recommend you to have your vehicle in-
spected as soon as possible. indication lamp blinks when the Active Stabili-
ty Control function or active

traction control func-
tion is operating. 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.
