Warning lamps
E00502400017Brake warning lamp (brake
warning buzzer)
E00502501712
This lamp illuminates
when the ignition
switch is turned to the “ON” position,
and goes off after a few seconds.
Always make sure that the lamp goes off
before driving.
With the ignition switch in the “ON” po-
sition, the brake warning lamp illumi-
nates under the following conditions:
l When the parking brake lever has
been engaged.
l When the brake fluid level in the
reservoir falls to a low level.
l When the brake force distribution
function or the brake system is not
operating correctly.
Brake warning buzzer
When there is a danger of brake perform-
ance becoming compromised,

a buzzer
will sound to alert the driver. If this buz-
zer should continue to sound, park your
vehicle in a safe place and we recom-
mend you to have it checked. NOTE
l Depressing
the brake

pedal repeat-
edly may turn on the brake warn-
ing lamp, ABS warning lamp and
brake warning buzzer. It is normal
if the lamp goes out and the buz-
zer stops sounding after a few sec-
onds. CAUTION
l
In the
situations
listed below,
brake performance may be com-
promised or the vehicle may be-
come unstable if brakes are ap-
plied suddenly; consequently,
avoid driving at high speeds or
applying the brakes suddenly.
Furthermore, the vehicle
should be brought to a stop in a
safe location and to have it
checked. • The brake warning lampdoes not illuminate when
the parking brake is applied
or does not turn off when
the parking brake is re-
leased.
• The ABS warning lamp and brake warning lamp illumi-
nate at the same time.
For details, refer to “ABS
warning lamp” on page
4-40.
• The brake warning buzzer does not turn off.
l The vehicle should be brought
to a halt in the following man- CAUTION
ner when brake performance
has deteriorated.
• Depress the brake

pedal
harder than usual.
Even if the brake pedal
moves down to the very end
of its possible stroke, keep it
pressed down hard.
• Should the brakes fail, use engine braking to reduce
your speed and pull the park-
ing brake lever.
Depress the brake pedal to
operate the stop lamp to
alert the vehicles behind you.
NOTE l In
certain cases

immediately after
the engine has been started or
when the brake pedal is depressed
repeatedly, a noise generated by
operation of brake devices may be
heard coming from the engine com-
partment. At this time, you may
feel a shock from the brake pedal
if you depress it. This type of
noise or shock is normal and there
is no need for concern. In fact,
they indicate that the correspond-
ing devices are operating normally.
l The brake system uses brake fluid
pressurized by the pump.

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
