WARNING
l If the
rear differential lock is used by mis-
take when turning a curve or making a
right or left turn at a crossing or the like:
The vehicle is unable to make a turn and
may go straight ahead. WARNING
l If the rear
differential lock is used by mis-
take except when making an emergency
escape on snow or frozen road: It be-
comes difficult to make a steady turn.
l In the case where the condition of the
road is different for the right tyre to
drive from the left tyre (such as one tyre
on a paved road and the other on ice), di-
rection of the vehicle may change abrupt-
ly when engine braking or accelerating.
Do not use the rear differential lock ex-
cept when making an emergency escape
on a snow or frozen road, but drive with
4WD. 4-wheel drive operation
E00606600627
By selecting 4-wheel

drive, both axles of the vehi-
cle are rigidly connected with each other. This im-
proves the traction characteristics. When turning
sharp corners or moving forward and backward re-
peatedly, however, the drive line is stressed, which
is felt as a braking effect. A 4-wheel drive vehicle
can accelerate more quickly and smoothly.
However, note that the braking distance is not short-
er than that of a rear-wheel drive vehicle.
When using 4-wheel drive on rough roads (snow,
mud, sand, etc.), it is important to operate the vehi-
cle correctly.
NOTE
l The driving posture should be more upright
and closer to the wheel than usual; adjust the
seat to a good position for easy steering and
pedal operation. Be sure to wear the seat belt.
l After driving on rough roads, check each
part of the vehicle and wash it thoroughly
with water. Refer to the “Vehicle care” sec-
tion and “Inspection and maintenance follow-
ing rough road operation” on page 4-35.
Driving on dry paved road and highway
Select the “2H” or “4H” position to drive on the
dry paved road. Especially on dry highway, never
select the “4HLc” or “4LLc” position. Starting and driving
4-32

OBKE12E1

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

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 E00606800401
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 9-12.
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 8-14. l Check the tyre inflation pressure regularly.
l If the tyre inflation pressure is inappropriate,
the transfer gear may make some noise and
shock while changing the drive mode. CAUTION
l
Always use tyres
of the same size, same
type, and same brand, and which have no
wear differences. Using tyres which differ
in size, type, brand or the degree of wear
will cause excessive loading, resulting in
possible damage to the drive system.
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 6-15. Starting and driving

OBKE12E1

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

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

• 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

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

E00610000550
In order
to
tow a trailer with your vehicle, when hav-
ing a trailer towing device mounted that meets all
relevant regulations in your area, consult a
MITSUBISHI MOTORS Authorized Service Point.
The regulations concerning the towing of a trailer
may differ from country to country. You are ad-
vised to obey the regulations in each area. CAUTION
l
Danger of Accident!
A towing
bar

should be fitted according
to MITSUBISHI MOTORS guidelines.
When you are going to tow a trailer,
move the transfer shift lever to “4H” posi-
tion.
Selecting the “2H” drive may increase the
differential oil temperature, resulting in
possible damage to the driving system.
Further, the drive train will be subjected
to excessive loading possibly leading to oil
leakage, component seizure, or other seri-
ous faults.
Maximum towable weight with brake
and maximum trailer-nose weight
Never exceed the

maximum towable weight with
brake and the maximum trailer-nose weight as lis-
ted in the specifications. (Refer to “Vehicle
weight” on page 9-07 .)
If you tow a trailer at an altitude of more than
1,000 m above sea-level, reduce your weight by
10 % of the gross combination weight for every in-
crease of 1,000 m above sea-level, as the engine out-
put is lowered owing to decrease in atmospheric
pressure. Towing bar mounting specifications
