ABS MITSUBISHI PAJERO IV 2011 User Guide

Anti-lock brake system (ABS)
E00607101248
Environmental conditions can
have an effect on
braking. During sudden braking when there is
snow, ice, oil, water etc. on the road surface, a skid
may occur. In this situation, steering control and
braking effectiveness is reduced and the stopping
distance is increased. The vehicle may also go into
an uncontrolled spin.
The ABS helps prevent the wheels from locking dur-
ing braking, thus maintaining directional stability,
ensuring controllability and providing optimum
braking force.
Driving hints
l Always maintain the same distance from the
vehicle in front of you as you would for a ve-
hicle not equipped with ABS.
Compared with vehicles not fitted with ABS,
your vehicle may require a longer stopping
distance in the following cases:
• Driving on gravel or snow-covered roads.
• Driving with tyre chains installed.
• Driving on roads where the road surfaceis pitted or has other differences in sur-
face height.
• Driving on bumpy roads or other poor driv- ing surfaces.
l In order to ensure that the ABS will operate
correctly in situations where tyre chains have
been fitted, drive in the “4H”, “4HLc”, or
“4LLc” position. l
Operation of
ABS is not restricted to situa-
tions where brakes are applied suddenly.
This system may also operate to prevent
wheel lock when you are driving over man-
holes, steel road-work plates, or the vehicle
is driven over steps or level differences in
the road, road markings, or other surfaces
which are difficult for the wheels to grip.
l When the ABS is activated, you may feel the
brake pedal pulsation and the vibrations of
the vehicle body and steering wheel. You
may also hear a characteristic noise. At this
time, you may feel as if the pedal attempts to
resist being depressed.
This is a normal result of the ABS operation,
and does not indicate a problem.
In this situation, to let the ABS work for
you, just hold the brake pedal down more
firmly. Do not pump the brake. This will
result in reduced braking performance.
l When the engine starts and after starting to
drive, you might hear operation noise from
the engine compartment or feel a shock from
the brake pedal. This is normal. The ABS is
performing self-check.
l The ABS will operate after the vehicle has ac-
celerated to a speed in excess of approximate-
ly 10 km/h (6 mph). It stops operating when
the vehicle decelerates to a speed below
about 5 km/h (3 mph). CAUTION
l
Even the ABS
cannot prevent the natural
laws of physics from acting on the vehi-
cle. It cannot for instance avoid accidents
that may result from excessive speed on
bends or following another vehicle too
closely or aquaplaning. It should remain
the driver’s task to observe safety precau-
tions to judge speeds and brake applica-
tions correctly in such conditions.
l Be sure to use tyres of the same type and
size on 4 wheels.
If tyre types or sizes are mixed, ABS may
not function normally.
l Never install a limited-slip differential,
which is not a MITSUBISHI MOTORS
genuine part, as the ABS may not func-
tion normally.
We recommend you to consult a
MITSUBISHI MOTORS Authorized
Service Point. 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.

Anti-lock brake system (ABS) ® p. 4-39
Active stability control function ® p. 4-43
Active traction control function ® p. 4-44 CAUTION
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
does not indicate 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, “Active
stability control function OFF indication
lamp” on page 4-43.

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.
l On vehicles with rear differential lock, the Ac-
tive Stability Control function does not oper-
ate when the rear differential lock is activated.

bility Control function
is deactivated by either of
the following operations:
l The ASC OFF switch is pressed to deacti-
vate the system.
l The transfer shift lever is placed in the
“4LLc” position. CAUTION
l
When indication lamp blinks, the Ac-
tive Stability Control

function is operat-
ing, which means that the road is slippery
or that your vehicle’s wheels are spinning
excessively. If this happens, drive slower
with less accelerator input.
l If a fault occurs in the device, the ABS
warning lamp or and indication
lamps illuminate as

warning. Park your
vehicle in a safe place and stop the en-
gine. Then, start the engine again and
check whether the ABS warning lamp or and indication lamps go out.
If the ABS

warning lamp or and in-
dication lamps remains
lit even after the
engine has been started, we recommend
you to have your vehicle checked. Starting and driving

from functioning properly. We recommend
you to have your vehicle inspected.
l The sensors do not detect objects located in
the area directly below or near the bumper. If
the height of an object is lower than the moun-
ted position of the corner or back sensors,
the sensors may not continue detecting it
even if they detected it initially.
For information on how to change the detection
areas, please refer to “Changing the detection
areas” on page 4-52. CAUTION
l
The reversing
sensor
system may not op-
erate properly under the following condi-
tions: • The sensors or surroundings are cov-ered with ice, snow, or mud.
• The sensors are frozen.
• The system receives ultrasonic noise from other sources (the horns of other
vehicles, motorcycle engines, brakes,
radios, pouring rain, splashing water,
tyre chains, etc.).
• The sensors are extremely hot or cold (while the vehicle is parked for a long
period of time under a blazing sun or
in cold weather).
• The vehicle tilts significantly.
• The vehicle is driven on a rough road (with a bumpy, gravel, hilly, or grassy
surface). CAUTION
• The vehicle is too close to an obstacle.
• The sensors
or

surroundings have
been wiped by hand, or stickers or ac-
cessories have been attached.
l The reversing sensor system may not prop-
erly detect the following:
• Objects that are thin, such as wirenets or ropes.
• Objects that absorb sound waves, such as snow.
• Objects that are shaped with a sharp angle.
• Objects with a smooth surface, such as glass.
• Objects that are low, such as kerb- stones.
NOTE l The
buzzer may

sound lower than the normal
warning sound when the reversing sensor sys-
tem is receiving ultrasonic noise from other
sources, but this is not a malfunction. The buz-
zer will stop sounding and the system will re-
turn to normal operation after the noise is no
longer received. Starting and driving

E00800600991
If the water

temperature gauge indication remains
in the overheating zone for a long time, the engine
may be overheating. If this occurs, take the follow-
ing corrective measures: 1. Stop the vehicle in a safe place.
2. Check whether steam is coming from the en-gine compartment.

[If steam does not come from the engine com-
partment]
With the engine still running, raise the bon-
net to ventilate the engine compartment.

[If steam is coming from the engine compart-
ment]
Stop the engine, and when the steam stops,
raise the bonnet to ventilate the engine com-
partment. Restart the engine. WARNING
l Do not
open
the bonnet while steam is com-
ing from the engine compartment. It
could cause steam or hot water to spurt
out, causing burns. Hot water could spurt
out even when there is no steam coming
out, and some parts will be very hot. Be
very careful when opening the bonnet.
l Be careful of hot steam, which could be
blowing off the reserve tank cap.
l Do not attempt to remove the radiator
cap while the engine is hot. For emergencies

l
Depressing the
brake pedal during travel on
snowy or icy roads may cause tyre slippage
and skidding. When traction between the
tyres and the road is reduced the wheels may
skid and the vehicle cannot readily be
brought to a stop by conventional braking
techniques. Braking will differ, depending
upon whether you have anti-lock brakes
(ABS). As your vehicle is equipped with
ABS, brake by pressing the brake pedal hard,
and keeping it pressed.
l Allow extra distance between your vehicle
and the vehicle in front of you, and avoid sud-
den braking.
l Accumulation of ice on the braking system
can cause the wheels to lock. Pull away from
a standstill slowly after confirming safety
around the vehicle. CAUTION
l
Do not
press
the accelerator pedal rapid-
ly. If the wheels break free of the ice, the
vehicle could suddenly start moving and
possibly cause an accident.

need them.
Don’t expect help from other people in
the cold.
l Choose a clear straight stretch of road
where you can pull over and still be seen
while you are fitting the chains.
l Do not fit chains before you need them.
This will wear out your tyres and the
road surface.
l After driving around 100-300 metres,
stop and retighten the chains. CAUTION
l
Drive carefully and
do not exceed
50 km/h (30 mph). Remember, fitting
chains is not going to stop accidents from
happening.
l When tyre chains are installed, take care
that they do not damage the disc wheel or
body.
l An aluminium wheel can be damaged by
a tyre chain while driving. When fitting a
tyre chain on an aluminium wheel, take
care that any part of the chain and fitting
cannot be brought into contact with the
wheel.
l When installing or removing the tyre
chains, take care that hands and other
parts of your body are not injured by the
sharp edges of the vehicle body.
NOTE l The
laws and

regulations concerning the use
of tyre chains vary. Always follow local laws
and regulations.
In most countries, it is prohibited by law to
use tyre chains on roads without snow. Parking brake break-in
E01008300010
