CAUTION
l
After
changing
the tyre and driving the ve-
hicle about 1,000 km (620 miles), retight-
en the wheel nuts to make sure that they
have not come loose.
l If the steering wheel vibrates when driv-
ing after changing the tyre, we recom-
mend you to have the tyres checked for
balance.
l Do not mix one type of tyre with another
or use a different size from the one listed.
This would cause early wear and poor han-
dling.
To store the flat tyre or spare tyre E00803400192
1. Attach the wheel to the spare wheel hanger
(A) while

aligning the holes in the wheel
with the bolts on the spare wheel hanger.
Using the wheel nut wrench, tighten the
spare wheel bolts firmly.

Tightening torque
37 to 54 Nm (Achieved by applying a force of 140 to
200 N
at the end of the wheel nut wrench sup-
plied with the vehicle.) 2. Reverse the opening procedure when closing
the spare wheel garnish.

Tightening torque

for spare wheel garnish
mounting bolt
11 to 25 Nm
(Achieved by applying a force of 40 to 92 N
at the end of the wheel nut wrench supplied
with the vehicle.) CAUTION
l
The spare
wheel
should always be se-
cured during vehicle operation. If a flat
tyre is changed, put the flat tyre in the
spare wheel mounting position, and use
the wheel nut wrench to secure it firmly.
NOTE l Have
your damaged

tyre repaired as soon as
possible. Towing
E00801503552
If your vehicle needs to be towed
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.
If a wheel gets stuck in a ditch, do not try to tow
the vehicle. Please contact your authorized
MITSUBISHI MOTORS dealer or a commercial
tow truck service for assistance.

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 “Emergency towing” in this part.
For emergencies

Towing with rear wheels off the ground (Type C)
Place the gearshift
lever in the “N” (Neutral) posi-
tion (M/T) or the selector lever in the “N” (NEU-
TRAL) position (A/T). Turn the ignition key to the
“ACC” position and secure the steering wheel in a
straight ahead position with a rope or tie-down
strap. Never place the ignition switch in the
“LOCK” position when towing.
Emergency towing
If towing service is not available in an emergency,
your vehicle may be temporarily towed by a rope
secured to the towing hook.
If your vehicle is to be towed by another vehicle or
if your vehicle tows another vehicle, pay careful at-
tention to the following points:
If your vehicle is to be towed by another vehicle
1. The front towing hooks (A) and rear towinghooks (B) are located as shown in the illustra-
tions. Secure the tow rope to the towing hook.
Front
Rear NOTE
l Using
a wire

rope or metal chain can result
in damage to the vehicle body. It is best to
use a non-metallic rope. If you use a wire
rope or metal chain, wrap it with cloth at any
point where it touches the vehicle body.
l Take care that the tow rope is kept as horizon-
tal as possible. An angled tow rope can dam-
age the vehicle body.
l Secure the tow rope to the same side towing
hook, to keep the tow rope as straight as pos-
sible.
2. Keep the engine running. If the engine is not running, turn the ignition
switch to the “ACC” or “ON” position to un-
lock the steering wheel. CAUTION
l
When the engine
is not running, the
brake booster and power steering pump
do not operate. This means higher brake
depression force and higher steering ef-
fort are required. Therefore, vehicle oper-
ation is more difficult than usual.
l Do not leave the key in the “LOCK” posi-
tion. The steering wheel will lock, causing
loss of control.
3. Place the gearshift lever in the “N” (Neutral)
position (with

M/T) or the selector lever in
the “N” (NEUTRAL) position (with A/T).
4. Shift the transfer shift lever to “2H” position.
5. Turn on the hazard warning lamps if required by law. (Follow the local driving laws and
regulations.)
6. During towing make sure that close contact is maintained between the drivers of both ve-
hicles, and that the vehicles travel at low
speed. CAUTION
l
Avoid sudden braking,
sudden accelera-
tion and sharp turning; such operation
could cause damage to the towing hooks
or the tow rope.
People in the vicinity could be injured as
a result.
l When towing or being towed down a long
slope, the brakes may overheat reducing
the effectiveness. In this situation, have
your vehicle transported by a tow truck. For emergencies

OBKE12E1

CAUTION
l
When the vehicle with A/T is to be towed
by another vehicle with all the wheels on
the ground, make sure that the towing
speed and distance given below are never
exceeded, avoiding damage to the trans-
mission.

Petrol-powered vehicles
Towing speed: 50 km/h (31 mph)
Towing distance: 50 km (31 miles)

Diesel-powered vehicles
Towing speed: 30 km/h (19 mph)
Towing distance: 80 km (50 miles)

For the towing speed and the towing dis-
tance, follow the local driving laws and
regulations.
If your vehicle tows another vehicle
Only use the

rear towing hook as shown in the illus-
tration. Secure the tow rope to the rear towing hook. CAUTION
l
When you are
going to tow another vehi-
cle, move the transfer shift lever to “4H”
position.
Selecting “2H” drive may increase the dif-
ferential oil temperature, resulting in pos-
sible 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.
NOTE l Do
not tow

a vehicle heavier than your own
vehicle. Operation under adverse driving
conditions E00801702326
On a flooded road l Avoid flooded
roads.

Water could enter the
brake discs, resulting in temporarily ineffec-
tive brakes. In such cases, lightly depress the
brake pedal to see if the brakes operate prop-
erly. If they do not, lightly depress the pedal
several times while driving in order to dry
the brake pads.
l When driving in rain or on a road with many
puddles a layer of water may form between
the tyres and the road surface.
This reduces a tyre’s frictional resistance on
the road, resulting in loss of steering stability
and braking capability.

To cope with this, observe the following items:
(a) Drive your vehicle at slow speed.
(b) Do not drive on worn tyres.
(c) Always maintain the specified tyre inflation pressures.
On a snow-covered or frozen road l When driving
on

a snow-covered or frozen
road, it is recommended that you use snow
tyres or tyre chains. Refer to the “Snow
tyres” and “Tyre chains” sections.
l Avoid high-speed operation, sudden acceler-
ation, abrupt brake application and sharp cor-
nering. For emergencies

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.
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. Maintenance

1. Turn the ignition switch to the “LOCK” or
“ACC” position.
2. Repeatedly
depress the brake pedal until sig-
nificant resistance is felt (normally after
about 40 times).
3. Check the brake fluid level in the reservoir. The brake fluid level must be between the
“MAX” and “MIN” marks on the reservoir.
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
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. CAUTION
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. Clutch fluid*
E01001000193
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 ensure that the clutch fluid level is always
between the “MAX” and “MIN” level markings on
the fluid reservoir.

OBKE12E1

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. WARNING
l Keep sparks,
cigarettes,
and flames away
from the battery because the battery
could explode. 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
Keep it out of reach of children.
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 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 Always wear protective eye goggles when
working near the battery. CAUTION
l
Do not bring
nearby parts, plastic parts
and so on into contact with sulphuric 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. Maintenance
