2010 MITSUBISHI GRANDIS maintenance

Diesel-powered vehicles (for
diesel particulate filter models)
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, and engine oil consumption is
greatly influenced by payload, engine speed, etc.
Therefore, it is important to check the oil level at
regular intervals or before starting a long trip.
This check must be made with the engine warm but
not running. Park the vehicle on a level surface,
stop the engine, and then wait a few moments to al-
low the engine oil in circulation to return to the oil
pan to ensure accurate measurement.
Remove the dipstick and wipe it with a clean cloth.
Reinsert the dipstick as far as it goes. Remove the
dipstick and read the oil level, which should al-
ways be within the range indicated.
If the oil level is below the specified limit, remove
the cap located on the cylinder head cover and add
enough oil to raise the level to within the specified
range.
Be sure to use the specified engine oil and do not
mix various types of oil. Also, avoid mixing differ-
ent makes of oil together if possible.
After adding oil, close the cap securely.
Use

only the recommended oils with an ACEA or
API classification as specified in this manual.
NOTE
l The engine oil will deteriorate rapidly if the
vehicle is subjected to severe conditions (for
example, repeated operation on rough roads,
in mountainous regions, on roads with many
uphill and downhill gradients, or over short
distances). Consequently, the oil will require
earlier replacement.
l For handling of used engine oils, refer to
page 06.
Selection of engine oil

Petrol-powered vehicles 1. Select
engine oil of the proper SAE viscosity
number according to the atmospheric temper-
ature.
SAE 0W-30, 5W-30, and 5W-40 engine oilscan only be used if they meet ACEA A3/B3,
A3/B4 or A5/B5 and API SG (or higher) spec-
ifications. 2. Use
engine oil conforming to the following
classification:
l API classification: “For service SG” or
higher
l ILSAC certificated oil
l ACEA classification:
“For service A1/B1, A3/B3, A3/B4 or
A5/B5”
NOTE l Use of additives is not recommended since
they may reduce the effectiveness of addi-
tives already included in the engine oil. It
may result in failure of the mechanical assem-
bly.

Diesel-powered vehicles Use engine oil conforming to the following
classification:• Vehicles with DPF= “VW 50700”
• Vehicles without DPF= “VW50501/50601/50700”
NOTE l Use of additives is not recommended since
they may reduce the effectiveness of addi-
tives already included in the engine oil. It
may result in failure of the mechanical assem-
bly. Maintenance

Engine coolant
E01000501361
To check the coolant level
A
translucent coolant reserve tank is located in the
engine compartment.
Petrol-powered vehicles
Check the coolant level in the reserve tank. The re-
serve tank lid (B) is equipped with a dipstick.

Remove the dipstick and wipe it with a clean cloth.
Reinsert the dipstick as far as it goes. Remove the
dipstick and read the coolant level, which should al-
ways be within the range “F” (FULL) or “L”
(LOW) while the engine is cold.
FULL
LOW 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 “L” (LOW) level
on the dipstick, add coolant to the reserve tank. Also, if the reserve tank is completely empty, re-
move

the radiator cap (A) and add coolant until the
level 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 severe 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 (minimum) °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.
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. Maintenance

Use only “BASF Glysantin Alu Protect
Premium/G30”.
It has excellent protection against corrosion and
rust formation of all metals including aluminium
and can avoid blockages in the radiator, heater, cyl-
inder 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 anti-freeze must fill 50 % concentration cool-
ant in all temperature conditions. 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 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. Add a sufficient
amount of anti-freeze to the coolant 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. Maintenance

Automatic transmission fluid*
E01000600857
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 P”
(PARK) to “D” (DRIVE), stopping momen-
tarily 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 oil 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. Washer fluid
E01000700164
Check

the float (A) is between the “FULL” and
“EMPTY” marks on the washer fluid reservoir.
If the level is low, replenish the container with wash-
er fluid. NOTE
l The

washer fluid container serves the wind-
screen, rear window and headlamps*.
During cold weather
To ensure proper operation of the washers at low
temperatures, use a fluid containing an anti-freez-
ing agent. Maintenance

Brake fluid/Clutch fluid*
E01000800501
The
brake fluid and the clutch fluid share the reser-
voir tank.

To check the fluid level
The fluid level must be between the “MAX” and
“MIN” marks on the reservoir. The fluid level is monitored by a float. When the
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 fluid level falls markedly in a short length of
time, it indicates leaks from the brake system.
If this occurs, we recommend you to have the vehi-
cle checked. Fluid type
Use

brake fluid conforming to DOT3 or DOT4
from a sealed container. The brake fluid is hygro-
scopic. Too much moisture in the brake fluid will
adversely affect the brake system, reducing the
brake performance. 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. Power steering fluid

Petrol-powered vehicles
Diesel-powered vehicles 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” level markings on the fluid reservoir
and refill the fluid, if necessary.
Fluid type
Use “Genuine MITSUBISHI Power Steering Flu-
id” or “ATF DEXRON III / DEXRON II”. Maintenance

Battery
E01001202014
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.
Checking battery electrolyte level
Petrol-powered vehicles
Diesel-powered vehicles 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 bat-
tery, first connect the positive (+) 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.
l Loosen the nut (B), and then disconnect the
battery cable from the positive (+) terminal.Petrol-powered vehicles
Diesel-powered vehicles 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
E01001300213 WARNING
l Driving
with tyres that are worn, dam-
aged or improperly inflated can lead to a
loss of control or blow out of the tyres
which can result in a collision with seri-
ous or fatal injury. Maintenance
