NOTE
As your vehicle is equipped with a tire pressure monitor-
ing system, there is a risk of damage to the tire inflation
pressure sensors when the tire is replaced on the rim. Tire
replacement should, therefore, be performed only by an
authorized Mitsubishi Motors dealer.

If you use new wheels with new tire inflation pressure
sensors, their ID codes must be programmed into the tire
pressure monitoring system. Refer to “Whenever the tires
and wheels are replaced with new ones” on page 3-156.
Braking
N00629500446
All the parts of the brake system are critical to safety. Have the
vehicle serviced by an authorized Mitsubishi Motors dealer or
a repair facility of your choice at regular intervals according to
the “WARRANTY AND MAINTENANCE MANUAL”.When brakes are wetCheck the brake system while driving at a low speed immedi-
ately after starting, especially when the brakes are wet, to con-
firm they work normally.
A film of water can be formed on the brake discs or brake
drums 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 driving slowly while lightly
depressing the brake pedal.When driving in cold weatherOn snowy roads, ice can form on the braking system, making
the brakes less effective. While driving in such conditions, pay
close attention to preceding and following vehicles and to the
condition of the road surface. From time to time, lightly
depress the brake pedal and check how effective the brakes are.When driving downhillIt is important to take advantage of the engine braking by shift-
ing to a lower gear while driving on steep downhill roads in
order to prevent the brakes from overheating.

N00733800151
The air conditioning system is equipped with an air filter to
remove pollen and dust.
The air filter’s ability to collect pollen and dirt is reduced as it
becomes dirty, so replace it periodically. For the maintenance
interval, refer to the “WARRANTY AND MAINTENANCE
MANUAL”.NOTE
Operation in certain conditions such as driving on a dusty
road and frequent use of the air conditioning can lead to
reduction of service life of the filter. When you feel that
the air flow is lower than normal or when the windshield
or windows start to fog up easily, replace the air filter.
Contact your Mitsubishi Motors dealer or a repair facility
of your choice for assistance.

N00734300919
The audio system can only be used when the ignition switch is
in the “ON” or “ACC” position.NOTE
To listen to the audio system while the engine is not run-
ning, turn the ignition switch to the “ACC” position.
If the ignition switch is left in the “ACC” position, the
accessory power will automatically turn off after a certain
period of time and you will no longer be able to use the
audio system. The accessory power comes on again if the
ignition switch is turned from the “ACC” position. Refer
to “ACC power auto-cutout function” on page 3-82.

If a cellular phone is used inside the vehicle, it may create
noise in the audio equipment. This does not mean that
anything is wrong with your audio equipment. In such a
case, use the cellular phone at a place as far as possible
from the audio equipment.

If foreign objects or water get into the audio equipment, or
if smoke or a strange odor comes from it, immediately
turn off the audio system and have it checked at an autho-
rized Mitsubishi Motors dealer or a repair facility of your
choice. Never try to repair it yourself. Avoid using the
audio system until it is inspected by a qualified person.

If the audio system is damaged by foreign objects, water,
or fire, have the system checked by a qualified Mitsubishi
Motors technician.

7-2 Vehicle care and maintenance
7Service precautions
N00937300299
Taking regular care of your vehicle will preserve its value and
appearance as long as possible.
You can do some of the maintenance work yourself, and the
rest should only be performed by an authorized Mitsubishi
Motors dealer or a repair facility of your choice.
If you discover a malfunction or other problem, have it cor-
rected by an authorized Mitsubishi Motors dealer or a repair
facility of your choice.
This section describes the maintenance inspections that you
can do yourself, if you so desire. Follow the instructions and
precautions for each procedure.
Have you purchased the Mitsubishi Motors Diamond Care Pro-
tection Plan? The Plan supplements your new vehicle warran-
ties. See your authorized Mitsubishi Motors dealer for details.
WARNING
!
When checking or servicing the inside of the engine
compartment, be sure the engine is stopped and has
had a chance to cool down.
If you need to work in the engine compartment with
the engine running, be especially careful that your
clothing, hair, etc. does not get caught in the fan,
drive belts, or other moving parts.
The fan can turn on automatically even if the engine
is not running. Turn the ignition switch to the
“LOCK” position to be safe while you work in the
engine compartment.
Do not smoke or allow open flames around fuel or
the battery. The fumes are flammable.

Be extremely careful when working around the bat-
tery. It contains poisonous and corrosive sulfuric
acid.
Do not get under your vehicle while it is on a jack.
Always use properly rated automotive jack stands.
Handling your vehicle’s parts and materials in the
wrong way can injure you. Ask an authorized
Mitsubishi Motors dealer or a repair facility of your
choice if you have questions.

7 Catalytic converter
N00937400131
The catalytic converter requires you to use unleaded fuel only.
Leaded gasoline will destroy the emission-control effective-
ness of the converter.
Normally, the catalytic converter does not require maintenance.
However, it is important to keep the engine properly tuned for
the converter to continue to work properly. To reduce the possibility of catalytic converter damage:

Use UNLEADED GASOLINE ONLY of the type of rec-
ommended in “Fuel selection”.

Do not drive with an extremely low fuel level. Running
out of gas could damage the catalytic converter.

Do not try to start the engine by pushing or towing the
vehicle. If the battery is weak or run down, use jumper
cables to properly start the engine.

Do not idle the engine with any spark plug wires discon-
nected or removed, such as when performing diagnostic
tests.

Do not idle the engine for a long time if it is idling
roughly or otherwise obviously malfunctioning.

To prevent the catalytic converter from being damaged
from unburned gas, do not race the engine when turning
off the ignition switch.

Stop driving the vehicle if you think the performance is
less than normal, the engine is running oddly or there is
any other engine trouble, such as with the ignition, etc. If
you are not able to stop driving immediately, slow down
and drive for only a short time. Have an inspection made
by an authorized Mitsubishi Motors dealer or a repair
facility of your choice as soon as possible.

In unusual situations involving major engine problems, a
burning odor may indicate severe and abnormal catalytic
converter overheating. If this occurs, stop in a safe place,
shut the engine off and let the vehicle cool. Once the
engine is cool, immediately take your vehicle to a dealer
or a repair facility of your choice for service.
CAUTION
!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. If
the engine malfunctions or misfires, or if your vehi-
cle performance suffers, have it serviced promptly.
Running your vehicle when it is overheated may
result in damage to the converter and vehicle.
WARNING
!
Do not park or run your vehicle in areas where com-
bustible materials such as dry grass or leaves can
come in contact with a hot exhaust, since a fire could
occur.
Do not put undercoat paint on the catalytic con-
verter.

Release the safety lever and lift the engine hood. NOTE
To prevent damage to the engine hood and wipers, make
sure the wipers are at resting position when you open the
engine hood. Support the engine hood with the hood prop. Insert the hood
prop securely in the opening under the hood marked with an
arrow.
CAUTION
!
Always insert the support prop into the hole spe-
cially made for it. Propping the engine hood at any
other place could cause the prop to slip out and lead
to an accident.
The hood prop can fall out if the hood is lifted by a
strong wind.

To check and refill engine oil It is normal for an engine to use oil. You may need to add oil
between the recommended oil change intervals. Before starting
the engine, check the engine oil level. Refill if necessary.
To check the oil level, remove the dipstick, wipe it off, and
gently insert it all the way into the crankcase. Slowly remove it
again. The oil level must not go above the line on the dipstick.
If the level does not reach the line, which shows the smallest
amount of oil required, remove the oil filler cap on the engine
valve cover, and fill to within the “Good” range. Except for vehicles with turbocharger
