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

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

Bleeding the fuel system (diesel-
powered vehicles only) E00800700149
The fuel system should be bled to remove air as de-
scribed below if the fuel supply is exhausted during
travel.

Pump the hand
pump (A) at the top of the fuel fil-
ter until the hand pump becomes stiff.
Then try again to start the engine.
If the engine does not start, repeat the process above. Removal of water from the fuel
filter (diesel-powered vehicles only) E00800800140
If the fuel
filter indication lamp in the instrument
panel illuminates during driving, it indicates that wa-
ter has accumulated in the fuel filter. If this occurs,
remove the water as described below. 1. Loosen the drain plug (A) at the bottom ofthe fuel filter. 2. Operate the hand pump (B) slowly 6 or 7
times in order to force the water out through
the drain plug. 3. Tighten the drain plug when water no longer
comes out.
4. Bleed the air in the fuel system.
(Refer

to “Bleeding the fuel system” on page
6-06.)
5. Check to be sure that the fuel filter indication lamp illuminates when the ignition switch is
turned to “ON”, and that it goes off when the
engine is started. If in doubt, we recommend
you to have your vehicle inspected. CAUTION
l
Do not
smoke
or have any other open
flame near the vehicle while bleeding the
fuel system.
l Be sure to carefully clean away any water
drained out because any fuel mixed with
the water could ignite and cause a fire. For emergencies

WARNING
l Do not open the radiator cap while the en-
gine is hot.
The coolant system is under pressure and
any hot coolant escaping could cause se-
vere burns.
Anti-freeze
The engine coolant

contains an ethylene glycol anti-
corrosion agent. The cylinder head and water pump
housing are cast aluminium alloy, and periodic
changing of the engine coolant is necessary to pre-
vent corrosion of these parts.

Use “DIA QUEEN SUPER LONG LIFE COOL-
ANT” or equivalent.
MITSUBISHI Genuine Coolant has excellent pro-
tection against corrosion and rust formation of all
metals including aluminium and can avoid block-
ages in the radiator, heater, cylinder head, engine
block, etc.

Because of the necessity of this anti-corrosion
agent, the coolant must not be replaced with plain
water even in summer. The required concentration
of anti-freeze differs depending on the expected am-
bient temperature. Ambient
temperature (mini-
mum) °C -15 -20 -25 -30 -35 -50 Anti-freeze
concentra- tion % 30 35 40 45 50 60 CAUTION
l
Do not use
alcohol or methanol anti-
freeze or any engine coolants mixed with
alcohol or methanol anti-freeze. The use
of an improper anti-freeze can cause cor-
rosion of the aluminium components.
l For effective anti-corrosion and anti-
freeze performance, keep the anti-freeze
concentration within the range of 30 to
60 %.
Concentrations exceeding 60 % will re-
sult in a reduction of both the anti-freeze
and cooling performance thus adversely
affecting the engine.
l Do not top up with water only.
During cold weather
The concentration should

be checked before the
start of cold weather and anti-freeze added to the
system if necessary to prevent damage to engine
and radiator due to freezing. Washer fluid

Windscreen washer fluid
The windscreen washer

fluid reservoir is in the en-
gine compartment.
Check the washer fluid level at regular intervals
and add washer fluid to reservoir if necessary. NOTE
l The
washer fluid

container serves the wind-
screen and headlamps (if so equipped). Maintenance
