2010 MITSUBISHI LANCER oil temperature

3-90 Features and controls
3Turbocharger operation
(if so equipped)
N00537300051
TurbochargerThe turbocharger increases engine power by pushing large
amounts of air into the engine’s cylinders. The finned parts
inside the turbocharger turn at extremely high speeds and are
subjected to extremely high temperatures. They are lubricated
by engine oil and cooled by engine oil and coolant. If the
engine oil is not replaced at the specified intervals, the bearings
may seize or emit abnormal noise.
CAUTION
!
Do not run the engine at high speeds (for example,
by revving it or by accelerating rapidly) immedi-
ately after starting it.
Do not stop the engine immediately after high-speed
or uphill driving. First allow the engine to idle to
give the turbocharger a chance to cool down.
Engine oil must be properly maintained to avoid
engine and/or turbocharger damage. To better pro-
tect your engine and turbocharger, use fully syn-
thetic engine oil.

NOTE
To protect the rubber parts of the wipers, this operation of
the wipers does not take place when the vehicle is station-
ary and the ambient temperature is about 32 °F (0 °C) or
lower.

Do not cover the sensor by affixing a sticker or label to the
windshield. Also, do not put any water-repellent coating
on the windshield. The rain sensor would not be able to
detect the extent of rain, and the wipers might stop work-
ing normally.

In the following cases, the rain sensor may be malfunc-
tioning. Have the vehicle checked at an authorized
Mitsubishi Motors dealer or a repair facility of your
choice.
• When the wipers operate at a constant interval despite
changes in the extent of rain.
• When the wipers do not operate even though it is rain-
ing.

The wipers may automatically operate when things such
as rain, dust, mud, insects, tree sap, oil or salt are affixed
to the windshield on top of the rain sensor or when the
windshield is frozen. (operation may also occur due to
strong electromagnetic waves, etc.) Objects affixed to the
windshield will stop the wipers when the wipers cannot
remove them.
To make the wipers operate again, move the lever to the
“LO” or “HI” position.

Contact an authorized Mitsubishi Motors dealer or a
repair facility of your choice when replacing the wind-
shield glass.
CAUTION
!
With the ignition switch in the “ON” position and
the lever in the “AUTO” position, the wipers may
automatically operate in the situations described
below.
• When cleaning the outside surface of the wind-
shield, if you touch the rain sensor.
• When cleaning the outside surface of the wind-
shield, if you wipe with a cloth the rain sensor.
• When using an automatic car wash.
• A physical shock is applied to the windshield.
• A physical shock is applied to the rain sensor.If your hands get trapped, you could suffer injuries
or the wipers could malfunction. To deactivate the
rain sensor, place the lever in the “OFF” position.

4 Driving during cold weather
N00629400298

Check the battery, including terminals and cables. During
extremely cold weather, the battery will not be as strong.
Also, the battery power level may drop because more
power is used for cold starting and driving.
Before driving the vehicle, check to see if the engine runs
at the proper speed and if the headlights are as bright as
normally. Charge or replace the battery if necessary. Dur-
ing extreme cold weather, it is possible that a very low
battery could freeze.

Warm the engine sufficiently. After starting the engine,
allow a short warm-up time to distribute oil to all cylin-
ders and turbocharger. Then drive your vehicle slowly.

Stay at low speeds at first so that the transaxle, transfer
case and rear axle oil have time to spread to all the lubri-
cation points.

Manual transaxle can be harder to shift in cold weather
conditions. This is normal and shifting will get easier as
the transaxle warms up.
Check the engine antifreeze.
If there is not enough coolant because of a leak or from
engine overheating, add high-quality ethylene glycol anti-
freeze and water. The recommended blend is about 50 %
water and 50 % anti-freeze. Use a higher concentration
(not over 60 %) when the outside temperature is -31 °F
(-35 °C) or lower. When the engine is working very hard
(for example, during mountain driving and/or when the
outside temperature is high), use a 50 % concentration.
This blend will provide adequate protection from corro-
sion and boiling.
[For RALLIART vehicles sold in U.S.A.]

Mitsubishi Motors recommends that the standard equip-
ment tires be replaced with winter tires when the vehicle
is going to be used in winter.
The standard equipment tires provided with this vehicle
are summer tires and use a high-grip compound that pro-
vides superior grip.
The road grip, however, is reduced in winter.
When replacing the standard equipment tires with winter
tires, all four tires must be replaced using radial identical-
size winter tires.
WARNING
!
The battery gives off explosive hydrogen gas. Any
spark or flame can cause the battery to explode,
which could cause serious injury or death.
Always wear protective clothes and a face mask
when working with your battery, or let a skilled
mechanic do it.
WARNING
!
Never open the radiator cap when the radiator is
hot. You could be seriously burned.

Recommended engine oil viscosity
N00955000041
Use engine oil with the proper thickness for the outdoor tem-
peratures where you will be driving.Except for vehicles with turbochargerSAE 5W-20 engine oil is strongly recommended for optimum
fuel economy and cold starting.
SAE 10W-30 may be used when the normal operating tempera-
ture is above 100 °F (38 °C).
Vehicles with turbochargerNOTE
Select engine oil of the proper SAE viscosity number
according to the atmospheric temperature. SAE 5W-30,
0W-30 and 0W-40 engine oil can only be used if it meets
API SM (or higher) specifications.

SAE 0W-30 and 0W-40 engine oil are recommended to
use to improve engine startability on a very cold weather
condition.

SAE 10W-30 may be used when the normal operating
temperature is above 100 °F (38 °C).

Use engine oil conforming to the following classification:
• API classification: “For service SM” or higher
• ILSAC certificated oil

Radiator capThe radiator cap must be tight sealed to prevent losing coolant
which may result in engine damage. Only use a Genuine
Mitsubishi Parts radiator cap, or an approved equivalent.
Points to remember
Do not overfill the reserve tank.

Your vehicle uses a special radiator cap that stays sealed
and lets the coolant flow from the reserve tank back to the
radiator when the engine cools down. If you need to
change the cap, use the exact same kind.

Check the coolant freeze point in the radiator with the
proper gauge, and only when it is safe. If you add anti-
freeze, the contents of the reserve tank must be protected
against freezing.

Keep the front of the radiator and condenser clean.

If the temperature of the engine coolant does not rise after
the engine is warmed-up, take your vehicle to an autho-
rized Mitsubishi Motors dealer or a repair facility of your
choice to have the thermostat checked, and replaced if
necessary.

Do not top off the tank with plain water only. Water
by itself boils at a lower temperature and does not
stop rust or freezing. If the water freezes, it will
damage your cooling system. Do not use tapwater. It
can cause corrosion and rust.
WARNING
!
Wait for the engine to cool down before opening the
radiator cap. Otherwise hot steam or boiling coolant
could spray up from the radiator and scald you.

Replacing tires and wheels
N00939600368
Tire maintenance
N00939700154
The following maintenance steps are recommended:

Check tire pressures regularly.

Have regular maintenance done on the wheel balance and
front and rear suspension alignment.

Rotate your tires regularly as described in the “Tire rota-
tion” section on page 7-36.
CAUTION
!
Avoid using different size tires and wheels from the
ones listed, and avoid the combined use of different
types of tires and wheels. Using different size or type
tires and wheels may affect driving safety.
Refer to “Tires and wheels” on page 9-10.
For All-wheel drive vehicles, always use tires of the
same size, same type, and same brand, and which
have no wear differences. Using tires that differ in
size, type, brand or the degree of wear, will increase
the differential oil temperature, resulting in possible
damage to the driving system. Further, the drive
train will be subjected to excessive loading, possibly
leading to oil leakage, component seizure, or other
serious problems.
Even if a wheel has the same rim size and offset as
the specified type of wheel, its shape may prevent it
from being fitted correctly. Consult an authorized
Mitsubishi Motors dealer or a repair facility of your
choice before using wheels that you have.
Only Mitsubishi Motors genuine wheels should be
used, because your vehicle is equipped with a tire
pressure monitoring system.
Use of another type of wheel risks air leaks and sen-
sor damage, as it will not be possible to install the
tire pressure sensor properly.

Genuine leather
(if so equipped)
N00945600161
1. To clean, lightly wipe the leather with a soft cloth soaked
in a 5 % solution of gentle soap and water.
2. To rinse, dip the cloth in fresh water, wring it out well, and
wipe off all the soap.
3. To preserve and protect, use a leather protecting agent on
the genuine leather surface. NOTE
If genuine leather is wet with water, wipe it with a dry,
soft cloth. If left damp, mildew may grow.

The genuine leather surface can be damaged if brushed
with a nylon or synthetic fiber brush.

Organic solvents such as benzine, kerosene, alcohol, gaso-
line, acid or alkaline solvents can discolor the genuine
leather surface and should not be used.

Genuine leather seats can mildew if not kept clean. Clean
up any oil stains immediately.

The genuine leather surface may harden and shrink if it is
exposed to the direct sunlight for long hours. When your
vehicle is parked, place it in the shade as much as possi-
ble.

When the temperature of the vehicle interior rises in sum-
mer, vinyl products left on the genuine leather seat may
deteriorate and stick to the seat.
Cleaning the outside of your vehicle
N00945700061
To protect your vehicle’s finish, wash it often and thoroughly.
If desired, you may wax your vehicle using a nonabrasive auto-
mobile wax. Foreign material
N00945800046
Industrial pollution, road tar, bird droppings, tree sap, insect
remains, sea water and other foreign matters can damage the
finish on your vehicle.
Generally, the longer any foreign material stays on the finish,
the worse the damage. Wash your vehicle as soon as possible
whenever the finish gets soiled.Wa s h i n g
N00945900526
Chemicals contained in the dirt and dust picked up from air,
rain, snow or road surfaces can damage the paint and body of
your vehicle if left on.
Frequent washing and waxing is the best way to protect your
vehicle from this damage.
Do not wash the vehicle in direct sunlight. Park the vehicle in
the shade and spray it with water to remove dust. Next, using
plenty of clean water and a car washing mitt or sponge, wash
the vehicle from top to bottom.
Use a mild car washing soap if necessary. Rinse thoroughly
and wipe dry with a chamois or soft cloth. After washing the
vehicle, carefully clean the joints and flanges of the doors,
hood, etc., where dirt is likely to remain.
