maintenance MITSUBISHI TRITON 2011 User Guide

The catalytic converter itself gets hot quickly, and
may be damaged if overheated.
The following
points should be noted in order to prevent the igni-
tion of unburned fuel within the catalytic converter.
l Do not drive with an extremely low fuel lev-
el; running out of fuel could cause damage to
the catalytic converter.
l Do not switch OFF the ignition switch while
driving.
l Do not attempt to start the engine by pushing
the vehicle. If the battery is weak or dis-
charged, use another battery to start the en-
gine.
l Do not idle the engine for prolonged periods
during very rough idle or malfunctioning op-
erating conditions.
l Do not race the engine when turning off the
ignition switch. This will cause the catalytic
converter to be damaged due to contact with
unburnt fuel.
l Stop driving the vehicle if you think the per-
formance is noticeably low, or if the engine
has a malfunction such as with the ignition,
etc.
If it is impractical to stop driving immediate-
ly, reduce the speed and drive for only a
short time. We recommend you to have your
vehicle inspected as soon as possible.
l In unusual situations involving major engine
problems, a burnt smell may indicate severe
and abnormal catalyst overheating.
If this occurs, the vehicle should be stopped
in a safe place, the engine switched off and
the vehicle allowed to cool. Once the engine
is cool, a service, including a tune-up to man-
ufacturer’s specifications, should be obtained
immediately. Bonnet

CAUTION
l
Note that the support bar may disengage
the bonnet if the open bonnet is lifted by
a strong wind.
l Always insert the support bar into the
hole provided specifically for this pur-
pose. Supporting the bonnet at any other
location could result in the support bar
slipping out and lead to an accident.
To close
Unlatch the support bar and clip it in its holder.
Slowly lower the bonnet to

a position about 20 cm
above the closed position, then let it drop. NOTE
l If
this does not close

the bonnet, release it
from a slightly higher position.
l Do not press down the bonnet hard with a
hand as it may damage the bonnet. CAUTION
l
Be careful that hands or
fingers are not
trapped when closing the bonnet.
l Before driving, make sure that the bon-
net is securely locked. An incompletely
locked bonnet can suddenly open while
driving. This can be extremely dangerous. Engine oil

To check and refill engine oil A- Minimum level
B- Maximum level
C- Oil replacement indication mark
Type 1Type 2 The engine oil used has a significant effect on the
engine’s performance, service life
and

startability.
Be sure to use oil of the recommended quality and
appropriate viscosity.
All engines consume a certain amount of oil during
normal operation. Therefore, it is important to
check the oil level at regular intervals or before start-
ing a long trip. 1. Park the car on a horizontal surface.
2. Switch off the engine.
3. Wait a few minutes.
4. Remove the dipstick and wipe it with a cleancloth.
5. Reinsert the dipstick as far as it goes.
6. Remove the dipstick and read the oil level, which should always be within the range in-
dicated. Maintenance

7. If the oil level is below the specified limit, re-
move the cap located on the cylinder head
cover and add enough oil to raise the level to
within the specified range. Do not overfill to
avoid engine damage. Be sure to use the speci-
fied engine oil and do not mix various types
of oil.
8. After adding oil, close the cap securely.
9. Confirm the oil level by repeating step 4 to 6.

Use only the recommended oils with an ACEA or
API classification as specified in this manual.
NOTE l Check or refill the oil according to the follow-
ing manner.
• When the oil level is checked in step 6above, check it on a low side of the dip-
stick because it is different in appearance
of oil level in the two sides of the dipstick.
• On vehicles without diesel particulate fil- ter (DPF), the oil level should be within
the range (A) to (B) on the dipstick.
• On vehicles with DPF, the oil level should be within the range (A) to (C) (oil
replacement indication mark) on the dip-
stick.
If the oil level is beyond the oil replace-
ment indication mark (C), replace the oil
as soon as possible.
Then, the oil should be refilled to the max-
imum level (B). • On vehicles with DPF, the engine oil will
increase due to a little fuel getting mixed
in the engine oil when the DPF regener-
ates to burn away the PM (particulate mat-
ter). However, it does not indicate a mal-
function.
l The engine oil will deteriorate rapidly if the
vehicle is subjected to severe conditions, re-
quiring earlier oil replacement. Please refer
to the maintenance schedule.
l For handling of used engine oils, refer to
page 05.
Selection of engine oil
Vehicles without diesel particulate filter (DPF) l
Select engine oil of
the
proper SAE viscosity

E01000501202
To check the coolant level
A translucent coolant reserve
tank
is located in the
engine compartment.
The coolant level in this tank should be kept be-
tween the “LOW” and “FULL” marks when meas-
ured while the engine is cold. To add coolant
The
cooling
system is
a

closed system and normal-
ly the loss of coolant should be very slight. A no-
ticeable drop in the coolant level could indicate leak-
age. If this occurs, we recommend you to have the
system checked as soon as possible.
If the level should drop below the “LOW” level on
the reserve tank, open the lid and add coolant.
Also, if the reserve tank is completely empty, re-
move the radiator cap and add coolant until the lev-
el reaches the filler neck. 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

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.
Water by itself reduces the rust-protec-
tive and anti-freeze qualities of the cool-
ant and has a lower boiling point. It can
also cause damage to the cooling system if
it should freeze. Do not use tapwater, as it
can cause corrosion and rust formation.
During cold weather
If the temperatures in your

area drop below freez-
ing, there is the danger that the coolant in the en-
gine or radiator could freeze and cause severe dam-
age to the engine and/or radiator. The concentra-
tion should be checked before the start of cold weath-
er and anti-freeze added to the system if necessary.
Add a sufficient amount of anti-freeze to the cool-
ant to prevent it from freezing.
The concentration should be checked before the
start of cold weather and anti-freeze added to the
system if necessary. Automatic transmission fluid*
E01000600974
The proper amount of automatic

transmission fluid
is essential to the life and operation of the automat-
ic transmission. Either insufficient fluid or exces-
sive fluid could cause transmission trouble. The
transmission fluid filler port cap is equipped with a
dipstick. Use the following procedure to check the
fluid level.
Procedure for checking the fluid level
1. Check the fluid level after the vehicle hasbeen driven enough to warm up the transmis-
sion fluid.
2. Park the vehicle on a flat, level surface and apply the parking brake.
3. With the engine idling and the brake pedal fully depressed, move the transmission selec-
tor lever through all the positions from the
"P” (PARK) to “L” (LOW) (with 4A/T), the
“P” (PARK) to “D” (DRIVE) (with 5A/T),
stopping momentarily at each position.
4. Move the selector lever to the “P” (PARK) position.
5. Remove the dipstick and wipe it with a clean lint-free cloth.
6. Reinsert the dipstick as far as it goes. 7. Remove dipstick and read the automatic trans-
mission fluid level.
The fluid level should
always be between the
two marks on the dipstick. WARNING
l Do not spill the
fluid
onto a hot exhaust
manifold during topping up or inspec-
tion, or a fire may occur.
Fluid type
Use only “DIA QUEEN ATF

SP III” transmission
fluid to ensure optimum transmission performance. Maintenance

Washer fluid
E01000700672
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).
During cold weather
To ensure proper operation of the washers at low
temperatures, use a fluid containing an anti-freez-
ing agent. Brake fluid
E01000900687
To check the fluid level
Check the brake fluid level in the reservoir.
The brake fluid level must

be between the “MAX”
and “MIN” marks on the reservoir. The brake fluid level is monitored by a float. When
the brake fluid level
falls

below the “MIN” mark,
the brake fluid warning lamp lights up.
The fluid level falls slightly with wear of the brake
pads, but this does not indicate any abnormality.
If the brake fluid level falls markedly in a short
length of time, it indicates leaks from the brake sys-
tem.
If this occurs, we recommend you to have the vehi-
cle checked.
Fluid type
Use brake fluid conforming to DOT3 or DOT4.
The brake fluid is hygroscopic. Too much moisture
in the brake fluid will adversely affect the brake sys-
tem, reducing the brake performance. In addition, the brake fluid reservoir is equipped
with a special cap
to

prevent the entrance of air,
and this cap should not be removed. CAUTION
l
Take care in handling
brake
fluid as it is
harmful to the eyes, may irritate your
skin and also damage painted surfaces.
l Use only the specified brake fluid.
Do not mix or add different brands of
brake fluid to prevent chemical reactions.
Do not let any petroleum-based fluid
touch, mix with, or get into the brake fluid.
This will damage the seals.
l Keep the reservoir tank cap closed to pre-
vent the brake fluid from deteriorating ex-
cept maintenance.
l Clean the filler cap before removing and
close the cap securely after maintenance. Maintenance

Clutch fluid*
E01001000281
To check the fluid level
The clutch fluid in the
master cylinder should be
checked when performing other underhood service.
In addition, the system should be checked for leak-
age at the same time.
Check to make certain that the clutch fluid level is
always between the “MAX” and “MIN” level mark-
ings on the fluid reservoir. A rapid fluid loss indicates a leak in the clutch sys-
tem which should be inspected
by a MITSUBISHI
MOTORS Authorized Service Point or another spe-
cialist and repaired immediately.
Fluid type
Brake fluid conforming to DOT 3 or DOT 4 should
be used.
The reservoir cap must be fully tightened to avoid
contamination from foreign matter or moisture.
DO NOT ALLOW PETROLEUM-BASED FLUID
TO CONTACT, MIX WITH, OR OTHERWISE
CONTAMINATE THE BRAKE FLUID. SEAL
DAMAGE WILL RESULT. WARNING
l Take
care
in handling
brake
fluid as it is
harmful to the eyes and may also cause
damage to painted surfaces. Wipe up any
spills immediately. Power steering fluid
E01001100703
To check the fluid level
Check the fluid level in

the reservoir while the en-
gine is idling.
Check to make certain that the power steering fluid
level is always between the “MAX” and “MIN” lev-
el markings on the fluid reservoir and refill the flu-
id, if necessary. Fluid type
Use “ATF DEXRON III or DEXRON II”. Maintenance

Battery
E01001202144
The condition of the battery
is very important for
quick starting of the engine and proper functioning
of the vehicle’s electrical system. Regular inspec-
tion and care are especially important in cold weath-
er.
NOTE
l On vehicles equipped with 2 batteries, when
the batteries are replaced, the 2 batteries
should be replaced at the same time.
If only a battery is replaced, it will cause short-
ening the batteries life.
Checking battery electrolyte level The electrolyte level must be between the specified
limit
on
the outside
of

the battery. Replenish with
distilled water as necessary.
The inside of the battery is divided into several com-
partments; remove the cap from each compartment
and fill to the upper mark. Do not top up beyond
the upper mark because spillage during driving
could cause damage. Check the electrolyte level at least once every 4
weeks, depending on the operating conditions.
If
the
battery is
not

used, it will discharge by itself
with time.
Check it once every 4 weeks and charge with low
current as necessary.
During cold weather
The capacity of the battery is reduced at low tem-
peratures. This is an inevitable result of its chemi-
cal and physical properties.
This is why a very cold battery, particularly one
that is not fully charged, will only deliver a fraction
of the starter current which is normally available.
We recommend you to have the battery checked be-
fore the start of cold weather and, if necessary,
have it charged or replaced.
This does not only ensure reliable starting, but a bat-
tery which is kept fully charged also has a longer life.
Disconnection and connection
To disconnect the battery cable, stop the engine,
first disconnect the negative (-) terminal and then
the positive (+) terminal.
When connecting the battery, first connect the posi-
tive (+) terminal and then the negative (-) terminal.
NOTE
l Open the terminal cover (A) before discon-
necting or connecting the positive (+) termi-
nal of the battery.Type 1
Type 2 WARNING
l Keep sparks, cigarettes, and
flames
away
from the battery because the battery
could explode. Maintenance

WARNING
l The battery electrolyte is extremely caus-
tic. Do not allow it to come in contact
with your eyes, skin, clothing, or the pain-
ted surfaces of the vehicle. Spilt electro-
lyte should be flushed immediately with
ample amounts of water.
Irritation to eyes or skin from contact
with electrolyte requires immediate medi-
cal attention.
l Ventilate when charging or using the bat-
tery in an enclosed space. CAUTION
l
Never
disconnect the
battery with
the ig-
nition switch in the “ON” position; doing
so could damage the vehicle’s electrical
components.
l Never short-circuit the battery; doing so
could cause it to overheat and be damaged.
l Always wear protective eye goggles when
working near the battery.
l If the battery is to be quick-charged, first
disconnect the battery cables.
l In order to prevent a short circuit, be
sure to disconnect the negative (-) termi-
nal first.
l Keep it out of reach of children. CAUTION
l
Do not bring the nearby
parts, the plastic
parts and so on into contact with sulphu-
ric acid (battery electrolyte) which may
crack, stain or discolour them.
If they are in contact, wipe off with soft
cloth, chamois or the like and an aqueous
solution of neutral detergent then imme-
diately rinse the affected parts with plen-
ty of water.
NOTE l Keep
the terminals clean. After

the battery is
connected, apply terminal protection grease.
To clean the terminals, use lukewarm water.
l Check to see if the battery is securely instal-
led and cannot be moved during travel. Also
check each terminal for tightness.
l When the vehicle is to be left unused for a
long period of time, remove the battery and
store it in a place where the battery fluid will
not freeze. The battery should be stored only
in a fully charged condition. Tyres
E01001300239 WARNING
l Driving with tyres that
are
worn, dam-
aged or improperly inflated can lead to a
