Trailer towing
Driving safety 6-15
6
Avoid jerky or sudden maneuvers. Signal well in advance. Towing a trailer puts additional burden on the engine and transaxle, which may cause over- heating. Following are some suggestions to reduce overheating: When towing at high altitudes, engine coolant and automatic transaxle fluid will overheat at a lower temperature than at normal altitudes.If you turn your engine off immediately after towing at high altitude on steep uphill grades, your vehicle may show signs similar to over-heating. To avoid this
, let the engine run
while parked (preferably on level ground)
with the automatic transaxle in the “P” (PARK) position for a few minutes before turning the engine off.  If the engine coolant temperature indica- tor flashes on the information screen in the multi-information display or the engine power drops suddenly, refer to “Engine overheating” on page 8-4.  If the warning display or warning display illuminates, refer to “Warning dis- play” on page 5-66.
Reduce speed and downshift before you start down a long or steep
downgrade. If you don’t
downshift, prolonged or frequent applicationof the brakes can cause reduced braking effi- ciency and performance. You can tow in “D” (DRIVE) position. How- ever, you may want to shift the selector leverto the 3rd or a lower position, under heavy loads or hilly conditions. Always place chocks or blocks under both the vehicle and trailer wheels when parking. Be sure that the parking brake is firmly set and
that the selector lever is in the “P” (PARK) position. Avoid parking on a hill with a trailer, but if it cannot be avoided, do so only after performing the following: 1. Apply the brakes and keep them applied. 2. Have someone place chocks or blocks under both the vehicle and trailer wheels. 3. When the chocks or blocks are in place,release your brakes slowly until the chocks or blocks absorb the load. 4. Apply the parking brake firmly.5. Set the selector lever to the “P” (PARK)position and turn off the engine.
When restarting out after parking on a hill: 1. Check that the selector lever is set to the “P” (PARK) position. 2. Start the engine. Be sure to keep the brakepedal depressed. 3. Set the selector lever to the “D” (DRIVE) position or “R” (REVERSE) position.4. Release the parking brake and brake pedal and slowly pull or
back away from the
chocks or blocks. Stop and apply yourbrakes. 5. Have someone retrieve the chocks or blocks.

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, until
you 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
area.
N00860700087
If the operation mode cannot be changed to OFF, perform the following procedure. 1. Move the selector lever to the “P” (PARK) position, and then change theoperation mode to OFF. 2. One of the other causes could be low bat- tery voltage. If this occurs, the keylessentry system and the F.A.S.T.-key opera- tion will also not operate. Contact an authorized Mitsubishi Motors dealer or arepair facility of your choice.
N00836401840
If the engine cannot be started because thebattery is weak or dead, you can start it with the battery from another vehicle using jumper cables.
1. Take off any metal jewelry such as watch bands or bracelets that might create anaccidental electrical contact. 2. Position the vehicles close enough together so that the jumper cables canreach, but be sure the vehicles aren’t touching each other. 3. Set the parking brake firmly on your vehi- cle and move the selector lever into the “P” (PARK) position.
If the vehicle breaks down If the engine stops/fails When the engine fails at the intersection

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 systemwarning light to blink on and off. This is only due to the low battery voltage. It is not a problem with the brake system. If this hap-pens, fully charge the battery and ensure thecharging system is operating properly.
N00836501421
When the engine is overheating, the informa-tion screen in the multi-information display will be interrupted and the engine coolant temperature warning display will appear. Also “ ” will blink. If these warnings are displayed: 1. Stop the vehicle in a safe place. Turn on the hazard warning flashers.2. With the engine still running, carefully raise the engine hood to vent the engine compartment.
3. Check that the cooling fan is running. If the 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 comingfrom under the hood, leave the engine on until the high coolant temperature warn- ing goes off. After the high coolant tem-perature warning has gone off, you can start driving again. If the high coolant temperature warning stays on, turn off theengine.
Charging the battery by using an external battery charger
WA R N I N G Always remove the battery from your vehicle when the battery is charged by anexternal battery charger. Keep sparks, cigarettes, and flames away from the battery because the battery could explode. 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 made of corro- sive diluted sulfuric acid. If electrolytecomes in contact with your hands, eyes, clothes, or the painted surface of your vehicle, thoroughly flush with water. Ifelectrolyte gets in your eyes, flush them immediately and 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.
As your vehicle has anti-lock brakes Engine overheating
WA R N I N G To avoid personal injury, keep hands, hair, jewelry and clothes away from the coolingfan. The cooling fan can start at any time.WA R N I N G Before raising the engine hood, check to see if there is steam or spray coming from under the hood. Steam or spray coming from an overheated engine could seriously scald you.Do not open the hood until there is no steam or spray.

6. When you do not see any more steam or spray, open the hood. Look for obvious leaks, such as a split radiator hose. Be careful as components will be hot. Anyleak source must be repaired. 7. If there is no obvious leak source, check the coolant level in the engine coolantreserve tank. If there is none, or if it is too low, slowly add coolant. 8. If the engine coolant reserve tank needscoolant, you will probably also need toadd coolant to the radiator. Do not loosen or remove the radiator cap until the engine has cooled down. 9. Start the engine, and slowly add coolant, up to the bottom of the filler neck. Useplain 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 thehigh coolant temperature warning does not come on.
11. Have the system inspected by your autho-
rized Mitsubishi Motors dealer or a repair facility of your choice.

 When driving on a road covered with snow or ice, use snow tires. Tire chains cannot be used on your vehicle. Theremay be state or local regulations about using snow tires. Always check the regu- lations in your local area before usingthem. Refer to “Snow tires” on page 9-18 and “Tire chains” on page 9-18.  Drive slowly. Do not make sudden starts or stops, sharp turns, or slam on thebrakes.  Allow extra distance between your vehi- cle and the vehicle in front of you, andavoid sudden braking.  If a skid occurs when the accelerator pedal is depressed, take your foot off thepedal. 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 roads, it may be difficult to move your vehicle dueto the brake being frozen. Depress the accelerator pedal little by little to move the vehicle when safe to do so.
 Drive as slow as poss
ible when driving on
bumpy, rutted roads or over potholes.
N00860600031
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 can make 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 getinto 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 in rain, a layer of water may form between the tires and the road surface(hydroplaning). 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 Do not depress the accelerator pedal rapidly. The vehicle could start moving when it breaks free from the ice, possibly resulting in an 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-profile tires or under- inflated tires are especially at risk for dam-age.
Fuel Pump Shut-off System
WA R N I N G Before attempting to restart the engine after a collision, always inspect the ground under the vehicle for leaking fuel. If a fuel leak is found or a fuel odor is detected, donot restart the engine.

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. To reduce the possibility of catalytic con- verter damage:  Use UNLEADED GASOLINE ONLY of the type recommended in “Fuel selection” on page 3-2.
 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.Refer to “Jump-starting the engine” on page 8-2.  Do not idle the engine with any spark plug wires disconnected or removed, such aswhen performing diagnostic tests.  Do not idle the engine for a long time if it is idling roughly or otherwise obviouslymalfunctioning.  To prevent damage to the catalytic con- verter from unburned gas, do not race theengine when turning off the ignition switch.  Stop driving the vehicle if you think the performance is noticeably low, or the engine has a malfunction 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 your vehicle checked at an authorized MitsubishiMotors 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, stopin a safe place, shut the engine off and let the vehicle cool. Once the engine is cool, immediately take your vehicle to anauthorized Mitsubishi Motors dealer or a repair facility of your choice for service.

It is normal for an engi
ne to use oil. You may
need to add oil between the recommended oilchange 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 reinsert it all the way.Slowly pull the dipstick straight out and check the oil level by checking the upper sur- face of the dipstick. Th
e oil level must not go
above the line on the dipstick. If the level does not reach the line which shows the minimum amount of oil required, remove the oil filler cap on the cylinder headcover, and fill to within the “Good” range.
 If you drive with the engine hood left open, a warning display appears on the information screen in the multi-information display.

The engine coolant reserve tank (A) lets you quickly see when you need to add coolant. When the engine is cold, the level of the cool- ant in the reserve tank should be between theFULL and LOW marks. The radiator usually stays full so there is no reason to remove the radiator cap (B) except when you check thecoolant 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 clogs in some parts of the engine. If you need to add co
olant often, or if the
level in the reserve tank does not drop when the 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.

CAUTION  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-freezeBelow -31 °F (-35 °C): 60 % concentration of anti-freeze You can check the concentration level with agauge from an automotive supply store, or your authorized Mitsubishi Motors dealer or service 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 temperature and does not stop rust or freezing. If the water freezes, it will damage your coolingsystem. Do not use tapwater. It can cause corrosion and rust.

The radiator cap must be
sealed tight to pre-
vent losing coolant, which may result inengine damage. Only use a Mitsubishi Motors Genuine Parts radiator cap, or an approved equivalent.  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 radiatorwhen the engine cools down. If you need to 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 protected against freezing.  Keep the front of the radiator and con- denser clean.
 If the engine coolant temperature does not rise after the engine is warmed-up, take your vehicle to an authorized Mitsubishi Motors dealer or a repair facility of yourchoice to have the thermostat checked, and replaced if necessary.
