warning MITSUBISHI PAJERO IV 2011 Repair Manual

CAUTION
l
Selecting the “4HLc” or “4LLc” position
to drive on dry paved road will increase
the fuel consumption with possible noise
generation and early tyre wear.
It may also increase the differential oil
temperature, resulting in possible dam-
age to the driving system.
Further, the drive train will be subjected
to excessive loading, possibly leading to
oil leakage, component seizure, or other
serious faults.
Driving on snowy or icy roads
Set the transfer

shift lever to the “4H” or “4HLc”
position in accordance with the road conditions,
and then gradually depress the accelerator pedal for
a smooth start.
NOTE
l The use of snow tyres and/or tyre chains is
recommended.
l In order to ensure that the anti-lock brake sys-
tem (ABS) will operate correctly in situa-
tions where tyre chains have been fitted,
drive in the “4H”, “4HLc” or “4LLc” position.
l Maintain a safe distance between vehicles,
avoid sudden braking, and use engine brak-
ing (downshifting). CAUTION
l
Avoid sudden braking,
sudden accelera-
tion, and sharp turning; such operations
could cause skidding and spinouts. Driving on sandy or muddy roads
Set the
transfer

shift lever to the “4HLc” or “4LLc”
position and then gradually depress the accelerator
pedal for a smooth start. Keep the pressure on the
accelerator pedal as constant as possible, and drive
at low speed. CAUTION
l
Do not
force
the vehicle or drive reckless-
ly on sandy surfaces. In comparison with
normal road surfaces, the engine and oth-
er drive-system components are put un-
der excessive strain when driving on such
a surface, and this could lead to accidents.
l If any of following conditions occur while
the vehicle is being driven, immediately
park your vehicle in a safe place and fol-
low these procedures:
• The needle in the temperature gaugeapproaches the overheating zone.
Refer to “Engine overheating” on
page 6-04.
• A/T fluid temperature warning lamp illuminates.
Refer to “When the A/T fluid temper-
ature warning lamp comes on” on
page 4-22. 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 with a rock-
ing motion. Move the selector lever rhythmi-
cally between 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. Starting and driving
4-33 4

OBKE12E1

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 the “4LLc” position 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
it up to confirm that the vehicle can handle
the grade.
Descending sharp grades
Set the transfer shift lever to the “4LLc” position,
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 it
down 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 the “4HLc” or
“4LLc” position at low speed, a slight difference in
steering may be experienced similar to as if the
brakes were applied. This is called tight corner brak-
ing and results from each of the 4 tyres being 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.
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 geographical
features before
attempting to cross a stream
and ford the stream where the water is as shal-
low as practicable.
2. Cross at a place where the water is less than 70 cm deep.
3. Set the transfer shift lever to the “4LLc” po- sition.
4. Drive slowly at a speed of approximately 5 km/h (3 mph) to avoid splashing too much
water. CAUTION
l
Do not
attempt
to cross a stream at a
place where the water is more than 70 cm
deep.
l Cross a stream temporarily for emergen-
cies and avoid doing so for a long period
of time.
l 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 driving slowly
while lightly depressing the brake pedal.
Inspect each part of the vehicle carefully.
NOTE l Because
the inside

of the vehicle is flooded
with water when crossing at a place where
the water is more than 50 cm deep, we recom-
mend you to have your vehicle inspected.
l Frequent crossing of streams can adversely af-
fect the life span of the vehicle; we recom-
mend you to take the necessary measures to
prepare, inspect, and repair the vehicle. Starting and driving

CAUTION
l
Be sure to shift the transfer shift lever to
the “2H” position. Never try to tow with
the transfer shift lever in the “4H”,
“4HLc” or “4LLc” positions and with
any of the wheels on the ground (Type A
or B). This could result in damage to the
vehicle’s driving system, or the vehicle
could become separated from the tow
truck and unexpected accident might re-
sult. 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.
If you can shift the transfer shift lever to the “2H” position.
If you cannot shift the transfer shift lever to the “2H”
position. 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

Braking
E00607001524
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 circuits
so that when one brake circuit fails, the other is
available to stop the vehicle. In this situation, even
if the brake pedal moves down to the very end of
its possible stroke, keep depressing the brake pedal
down harder than usual; stop driving as soon as pos-
sible and have the brake system repaired.
For details, refer to “Brake warning lamp” on page
3-09.
Power brakes
The power brakes use brake fluid pressurized by
the pump to power-assist the brake. If the brake sys-
tem fails during driving, the brake warning lamp
comes on and a buzzer sounds continuously. In this
case, the brake may not work properly.
If this buzzer should continue to sound, park your
vehicle in a safe place and have the system checked.
Refer to “Brake warning lamp” on page 3-09. CAUTION
l
Bring the vehicle
to halt in a safe location
by applying the brakes gently. Applying
the brakes rapidly or driving at high
speed may make the vehicle unstable.
NOTE l Depressing
the brake

pedal repeatedly may
turn on the brake warning lamp, ABS warn-
ing lamp and brake warning buzzer. (The
ASTC indication lamp and Active Stability
Control function OFF indication lamp also
turn on.) It is normal if the lamp goes out
and the buzzer stops sounding after a few sec-
onds.
l In certain cases immediately after the engine
has been started or when the brake pedal is
depressed repeatedly, a noise generated by op-
eration of brake devices may be heard com-
ing from the engine compartment, or the
brake pedal vibration may be felt. This type
of noise or vibration is normal and there is
no need for concern. In fact, it indicates that
the corresponding devices are operating nor-
mal. 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 l The
brake warning

lamp illuminates to indi-
cate a fault in the braking system. Read
“Brake warning lamp” on page 3-09.
l On vehicles with the rear differential lock,
the active stability & traction control
(ASTC) and anti-lock brake system (ABS)
functions are suspended while the rear differ-
ential lock is activated. ASTC indication
lamp, Active Stability Control function OFF
indication lamp, ABS warning lamp and
brake warning lamp are illuminated while
these functions are suspended. It does not in-
dicate a problem. When the rear differential
lock is disengaged, these lamps go out and
function again.
Refer to “Brake warning lamp” on page 3-09,
“ABS warning lamp” on page 4-40, “ASTC
indication lamp” on page 4-42, “Active sta-
bility control function OFF indication lamp”
on page 4-43.
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
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 driv-
ing slowly while lightly depressing the brake pedal. Starting and driving
4-37 4

OBKE12E1

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. WARNING
l 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 the floor
mat is securely held in place.
Brake pads l Avoid hard braking situations.
New
brakes need

to be broken-in by moder-
ate use for the first 200 km (125 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.
If you hear this sound, have the brake pads re-
placed immediately. WARNING
l Driving with worn
brake pads will make
it harder to stop, and can cause an acci-
dent. Brake assist system
E00627000376
The brake assist system is a device assisting drivers
who cannot depress

the brake pedal firmly when it
is necessary to do so (such as in emergency stop sit-
uations) and provides greater braking force.

If the brake pedal is depressed suddenly, the brakes
will be applied with more force than usual. CAUTION
l
The brake
assist
system is not a device de-
signed to exercise braking force greater
than its capacity. Make sure to always
keep a sufficient distance between vehi-
cles in front of you without relying too
much on the brake assist system.
NOTE l 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.
l When the brake assist system is in use while
driving, you may feel the brake pedal at-
tempt to resist, the pedal moves in small mo-
tions in conjunction with the operation noise,
or the vehicle body and the steering wheel vi-
brate. This occurs when the brake assist sys-
tem is operating normally and does not indi-
cate faulty operation. Continue to firmly de-
press the brake pedal. l
When
the
anti-lock
brake system warning
lamp is illuminated, the brake assist system
is not functioning. Starting and driving

ABS warning lamp
E00607200532
The ABS warning
lamp should illuminate when the
ignition switch is turned “ON”, and should go off
in a few seconds. CAUTION
l
If the
warning
lamp stays on or does not
illuminate when you start the vehicle, it in-
dicates that the ABS is not functioning
and that only the standard brake system
is in operation. (In this condition the stand-
ard hydraulic brake system will still func-
tion.) We recommend you to have your ve-
hicle inspected as soon as possible. NOTE
l Depressing
the brake

pedal repeatedly may
turn on the brake warning lamp, ABS warn-
ing lamp and brake warning buzzer. (The
ASTC indication lamp and Active Stability
Control function OFF indication lamp also
turn on.) It is normal if the lamp goes out
and the buzzer stops sounding after a few sec-
onds.
l On vehicles with the rear differential lock,
the active stability & traction control
(ASTC) and anti-lock brake system (ABS)
functions are suspended while the rear differ-
ential lock is activated. ASTC indication
lamp, Active Stability Control function OFF
indication lamp, ABS warning lamp and
brake warning lamp are illuminated while
these functions are suspended. It does not in-
dicate a problem. When the rear differential
lock is disengaged, these lamps go out and
function again.
Refer to “Brake warning lamp” on page 3-09,
“ASTC indication lamp” on page 4-42, “Ac-
tive stability control function OFF indication
lamp” on page 4-43. If the warning lamp illuminates while
driving
E00607300416
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, we recommend you
to have the vehicle inspected.
If the ABS warning lamp and brake warning
lamp illuminate at the same time l The ABS and brake force distribution func-
tion will 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 we rec-
ommend you to have it checked. Starting and driving

Inspection following snowy road oper-
ation
E00618300012
After driving on
snowy roads, remove any snow
and ice which may have become adhered to the
wheel areas.
When doing this, be careful not to damage the
wheel speed sensors (A) and cables located at each
wheel on vehicles equipped with an ABS.
Front
Rear 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) E00613800230
The active stability

& traction control (ASTC)
takes overall control of the anti-lock brake system,
Active Stability Control function and active trac-
tion control function to maintain the vehicle’s sta-
bility and traction. Please read this section in con-
junction with the pages on the anti-lock brake sys-
tem, Active Stability Control function and active
traction control function.

l
Do not
over-rely
on the ASTC. Even
when the ASTC is operating, there are lim-
its to how far it can ensure vehicle stabili-
ty; reckless driving may lead to accidents.
Always drive carefully, taking account of
the road conditions.
l Be sure to use the same specified type and
size of tyre on all 4 wheels. Otherwise,
there is a possibility that the ASTC will
not work properly.
NOTE l An
operation noise

may be emitted from the
engine compartment in the following situa-
tions. The sound is associated with checking
the operations of the ASTC. At this time,
you may feel a shock from the brake pedal if Starting and driving

you depress it. These do not indicate a mal-
function.
• When the ignition
switch is set to the
“ON” position.
• When the vehicle is driven for a while af- ter the engine is turned on.
l When the ASTC is activated, you may feel a
vibration in the vehicle body or hear a whin-
ing sound from the engine compartment.
This indicates that the system is operating nor-
mally. It does not indicate a malfunction.
l When the anti-lock brake system warning
lamp is illuminated, the ASTC is not active.
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, Active Stability Con-
trol function OFF indication lamp, ABS warn-
ing lamp and brake warning lamp are illumi-
nated while these functions are suspended. It

Driving hints
E00618100036
When extricating the
vehicle from mud, sand or
fresh snow with the transfer shift lever in the “2H”,
“4H”, or “4HLc” position, you may find that opera-
tion of the ASTC prevents the engine speed from in-
creasing in response to depression of the accelera-
tor pedal. If this happens and the vehicle remains
stuck as a result, place the transfer shift lever in the
“4LLc” position or turn the Active Stability Con-
trol switch OFF. The vehicle will then be easier to
extricate. (Brake control of the active traction con-
trol function is still working to prevent wheel spins
when ASC OFF switch “OFF” or “4LLc” position
selected.)
NOTE
l If the vehicle speed increases to about
120 km/h (75 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 stability control function E00613900097
The Active Stability Control function is designed
to help maintain

the vehicle’s control in slippery
conditions, or during rapid steering manoeuvres. It
works by controlling the engine output and brake
on each wheel. NOTE
l The
Active Stability

Control function does
not operate when the transfer shift lever is in
the “4LLc” position.
When the Active Stability Control function
is operating with the transfer shift lever in
the “2H”, “4H” or “4HLc” position, moving
the shift lever to the “4LLc” position makes
the Active Stability Control function deacti-
vate automatically.

spected.
Active traction control function E00614100041
The active traction control function maintains trac-
tion on slippery

road surfaces by automatically con-
trolling the engine output and applying the brakes
so the driving wheels are prevented from spinning.
The active traction control function automatically
turns ON when the ignition switch is turned to the
“ON” position. CAUTION
l
If the temperature
in the braking system
increases excessively due to continuous
brake control on a slippery road surface,
a warning buzzer will sound intermittent-
ly to warn the driver. If driving continues
in spite of the buzzer and the tempera-
ture in the braking system increases fur-
ther, the indication lamp will illumi-
nate, the warning

buzzer will sound con-
tinuously for approximately 3 seconds,
