If your vehicle breaks down on the road, move to the shoulder and turn on the hazardwarning flashers. If there is no shoulder, or the shoulder is not safe, drive in the right lane slowly, with the hazard lights flashing, untilyou come to a safe stopping place. Keep the flashers flashing. If the engine stops, there will be no power assist to the steering and brakes, making these difficult to use.  The brake booster will not work, so the brakes will not grip well. The brake pedalwill be harder to press than usual.  Since there is no power steering assist, the steering wheel will be hard to turn.
Get help from your passengers, bystanders, etc. to push the vehicl
e and move it to a safe
zone.

If the engine cannot be started because the battery is weak or dead, you can start it withthe battery from another vehicle using jumper cables. 1. Take off any metal jewelry such as watch bands or bracelets that might make an accidental electrical contact. 2. Position the vehicles close enough together so that the jumper cables can reach, but be sure the vehicles aren’ttouching each other.
3. You could be injured if the vehicles move. Set the parking brake firmly on each vehi-cle. Put an automatic transaxle, CVT or Twin Clutch SST in “P” (PARK) or a manual transaxle in “N” (Neutral). Turnthe ignition key to the “LOCK” position. 4. Make sure your battery electrolyte is at the proper level. (Refer to “Checking bat- tery electrolyte level” on page 9-15.)

Jump-starting the engine
WA R N I N G When using jumper cables to start a vehi- cle, follow the procedures and be very cau- tious. CAUTION Do not try to start your vehicle by pushing or towing. Vehicles with continuously variable transmission (CVT) or Twin Clutch SST cannot be started this way. Pushing or towinga vehicle that has a manual transaxle may overheat and damage the catalytic converter. Also, there is more ri
sk of an accident when
a vehicle is being pushed or towed.
CAUTION Check the other vehicle. It must have a 12- volt battery. If the other system isn’t 12-volt, both systems can be damaged.WA R N I N G Turn the ignition key to the “LOCK” posi- tion on both vehicles. Make sure that thecables or your clothes cannot be caught by the fan or drive belt. Personal injury could result. NOTE
 Turn off all lights, heater, and other electrical loads. This will avoid sparks and help save both batteries.

Engine overheating 8-4 For emergencies
8
If you drive your vehicle with a low battery charge, after the engine has been started by
using jumper cables, the engine may misfire. This can cause the anti-lock braking system warning light to blink on and off. This is only due to the low battery voltage. It is not aproblem with the brake system. If this hap- pens, fully charge the battery and ensure the charging system is operating properly.
N00836500323
When the engine has overheated, the infor- mation screen in the multi-information dis- play will be interrupted and the enginecoolant temperature warning display will appear. The screen will then change to the engine coolant temperature display screen and “ ” will flash. If this happens: 1. Stop the vehicle in a safe place. Turn on the hazard warning flashers. 2. With the engine still running, carefullyraise the engine hood to vent the engine compartment. 3. Check that the cooling fan is running. Ifthe fan is not turning, stop the engine immediately and contact an authorized Mitsubishi Motors dealer or a repair facil-ity of your choice for assistance.
4. If you see steam or spray coming from under the hood, turn off the engine.5. If you do not see steam or spray coming from under the hood, leave the engine on until the bar graph for the engine coolanttemperature warning display on the multi-information display goes down. When it is in the middle of the normal zone, you can start driving again. If the bar graphstays in the red zone, turn off the engine. 6. When you do not see any more steam or spray, open the hood. Look for obvious leaks, such as a split radiator hose. Becareful as components will be hot. Any leak source must be repaired.
WA R N I N G Charging your battery while it is still in your vehicle might cause the battery to catch fire and explode. If you have to charge it while in the vehicle, disconnect the negative terminal.  Keep sparks, cigarettes and flames away from the battery because the battery mayexplode. Keep your work area well vented when charging or using the battery in an enclosed space.  Remove all the caps before charging the battery.  Electrolyte (battery acid) is corrosive diluted sulphuric acid. If electrolyte comes in contact with your hands, eyes, clothes,or the painted surface of your vehicle, thoroughly flush with water. If electrolyte gets in your eyes, flush them immediatelyand thoroughly with water, and get prompt medical attention. Always wear protective clothing and gog- gles when working near the battery. Keep the battery out of the reach of chil- dren.

7. If there is no obvious leak source, check the coolant level in the reserve tank. If there is none, or if it is too low, slowly add coolant.8. If the reserve tank needs coolant, you will probably also need to add coolant to the radiator. Do not loosen or remove theradiator cap until the engine has cooled down. 9. Start the engine, and slowly add coolant, up to the bottom of the filler neck. Use plain water if you have to (and replace it with the right coolant as soon as possible).
10. Replace the radiator cap and tighten it
fully. Check the engine coolant tempera- ture display on the multi-information dis-play. You can start driving again when the bar graph for the engine coolant tempera- ture display returns to the normal zone.
11. Have your vehicle checked by your autho-
rized Mitsubishi Motors dealer or a repair facility of your choice.

If your vehicle becomes stuck in snow, sand, or mud, it can often be
moved by a rocking
motion. Rock your vehicle back and forth to free it. Do not rev the engine or spin the wheels.Constant efforts to free a stuck vehicle can cause overheating and transaxle failure. Let
the engine idle for a few minutes to cool the transaxle before trying again. If your vehicle is still stuck after several rock- ing attempts, call for a commercial tow truckservice.
 [For front-wheel drive vehicle equipped with the active stability control (ASC)] If the vehicle is towed with the ignition switch in the “ON” position and only the front wheels or only the rear wheels raisedoff the ground, the ASC may operate, result- ing in an accident. When towing the vehicle with only the front wheels or only the rearwheels raised, keep the ignition switch in the “LOCK” or “ACC” position. [For vehicle equipped with the Electronically controlled 4WD system] Even in “2WD” mode, the vehicle cannot betowed with the front or the rear wheels on the ground.
Towing manual transaxle vehicles with rear wheels off the ground (Type B)
CAUTION
Towing with front wheels off the ground (Type C)
WA R N I N G To prevent entry of exhaust gas from the towing vehicle, set the selection switch to the recirculation position.
Operation under adverse driving conditions If your vehicle becomes stuck in sand, mud or snow
WA R N I N G When trying to rock your vehicle out of a stuck position, make sure that there are no people nearby. The rocking motion canmake your vehicle suddenly lurch forward or backward, and injure any bystanders.
On wet roads
CAUTION Avoid flooded roads. Water is often deeper than it looks, and you could be seriously hurt by driving into flood water.  When driving in rain, on water-covered roads, or through a car wash, water could get into the brake discs and make them fail tem-porarily. In such cases, lightly press the brake pedal to see if they are working prop- erly. If they are not, press the pedal lightly several times while driving to dry the brake pads or linings, then check them again.

 When driving on a road covered with snow or ice, use snow tires. Tire chains cannot be used on your vehicle. There may be state or local regulations aboutusing snow tires. Always check the regu- lations in your local area before using them. Refer to the section entitled “Snowtires” on page 9-24 and “Tire chains” on page 9-24.  Drive slowly. Do not make sudden starts or stops, sharp turns, or slam on the brakes.  Allow extra distance between your vehi- cle and the vehicle in front of you, and avoid sudden braking.  If a skid occurs when the accelerator pedal is depressed, take your foot off the pedal. Steer gently in the direction of the skid.
 Your vehicle is equipped with an anti-lock braking system (ABS), hold the brake pedal down firmly and keep it depressed. Do not pump the brake pedal which willresult in reduced braking performance.  After parking on snowy or icy road, it may be difficult to move your vehicle dueto freeze-up of the brake. Depress the accelerator pedal little by little to move the vehicle after confirming safety of thevehicle.  Drive as slow as poss
ible when driving on
bumpy or rutted roads or over potholes etc.
N00860600044
In the event of a collision causing frontal air-bag deployment, the fuel pump shut-off sys- tem will activate to stop fuel supply to the engine.
 When driving in rain, a layer of water may form between the tires and the road surface (aquaplaning). This loosens your tires’ grip on the road, making it difficult to steer or brake properly. When driving on a wet road:• Drive your vehicle at a safe speed.• Do not drive on worn tires.• Always keep the tires at the correct infla-tion pressures.
On snowy or icy roads
CAUTION
CAUTION Do not depress the accelerator pedal rapidly. The vehicle could start moving when it breaks free from the ice, possibly resulting inan accident.
On a bumpy or rutted road
CAUTION Driving on bumpy, rutted roads or over pot- holes can damage the tires and wheels.Wheels with low-profiles tires or under- inflated tires are especially at risk for dam- age.
 The vehicle’s body, bumper, muffler and other parts may be damaged if the vehicle is:• driven over a step (for example, at the entrance or exit of a parking lot);• parked too closely against a curb or parkingblock, or by the side of a road with curb-stones;• driven on a steep slope;

The catalytic converter requires you to useunleaded fuel only. Leaded gasoline will destroy the emission-control effectiveness of the converter. Normally, the catalytic converter does not require maintenance. However, it is important to keep the engine properly tuned for the con- verter to continue to work properly.
Service precautions
WA R N I N G When checking or servicing the inside of the engine compartment, be sure theengine is stopped and has had a chance to cool down.  If you need to work in the engine compart- ment with the engine running, be espe-cially 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 igni- tion switch to the “LOCK” position to be safe while you work in the engine com- partment. Do not smoke or allow open flames around fuel or the battery. The fumes are flamma-ble.  Be extremely careful when working around the battery. It contains poisonous and corrosive sulfuric acid.  Do not get under your vehicle while it is on a jack. Always use properly rated automotivejack stands.  Handling your vehicle’s parts and materi- als in the wrong way can injure you. Ask an authorized Mitsubishi Motors dealer or a repair facility of your choice if youhave questions. WA R N I N G

Mitsubishi Motors Genuine 5W-30 Engine Oil is the recommended oil for optimum engine performance and protection. SAE 0W-30 or 0W-40 engine oil is recom-mended to improve engine starting in cold weather conditions. Refer to temperature chart.
N00955100042
The oil filter should be replaced at the time ormileage specified in the “WARRANTY ANDMAINTENANCE MANUAL”. Only use high quality replacement filters on this vehicle. The manufacturer’s specifica-tions for Genuine Mitsubishi oil filters require that the filter can withstand a pressure of 256 psi (1.8 MPa). A Genuine Mitsubishioil filter is the best replacement filter.Follow the installation
instructions printed on
the filter.
N00937800542
The coolant reserve tank (A) lets you quickly see when you need to add coolant. When the engine is cold, the level in the reserve tank should be between the “FULL” and “LOW”marks. The radiator usually stays full so there is no reason to remove
the radiator cap (B)
except when you check the coolant freeze point or replace the antifreeze coolant.

Mitsubishi Motors Genuine Coolant provides excellent protection against corrosion and rust formation on all metals, including alumi-num, and prevents blockages in some parts of engine. If you need to add co
olant often, or if the
level in the reserve tank does not drop whenthe engine cools, the cooling system should be pressure-tested for leaks. Take your vehi- cle to an authorized
Mitsubishi Motors dealer
or a repair facility of your choice for testing.
The radiator cap must be tight sealed to pre- vent losing coolant which may result in engine damage. Only use a Genuine Mitsubi-shi Parts radiator cap, or an approved equiva- lent.  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 needto change the cap, use the exact same kind.  Check the coolant freeze point in the radi- ator with the proper gauge, and only when it is safe. If you add antifreeze, the con- tents of the reserve tank must be protectedagainst freezing.  Keep the front of the radiator and con- denser clean.  If the temperature of the engine coolant does not rise after th
e engine is warmed-
up, take your vehicle to an authorized Mitsubishi Motors dealer or a repair facil-ity of your choice to have the thermostat checked, and replaced if necessary.

The air cleaner filter w
ill get dirty and dusty
from use and not filter properly. Replace it with a new filter using the schedule in the“WARRANTY AND MAINTENANCE MANUAL”. 1. Remove the clips (A), then remove the duct (B).
* : similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrate and non-borate coolant with long life hybrid organic acid technologyCAUTION Do not use alcohol or methanol antifreeze or any engine coolants that contain them. Using the wrong antifreeze can corrode aluminum parts.  The required concentration of anti-freeze dif- fers depending on the expected ambient tem-perature. Above -31 °F (-35 °C) : 50 % concentration of anti-freeze Below -31 °F (-35 °C) : 60% concentration of anti-freezeYou can check the concentration level with a gauge from an automotive supply store, or your authorized Mitsubishi Motors dealer orservice station can check it for you.
 Do not use water to adjust the concentration of coolant.  Do not top off the tank with plain water only. Water by itself boils at a lower temperatureand does not stop rust or freezing. If the water freezes, it will damage your cooling system. Do not use tapwater. It can causecorrosion and rust.
Radiator cap
WA R N I N G Wait for the engine to cool down before opening the radiator cap. Otherwise hotsteam or boiling coolant could spray up from the radiator and scald you.
