Starting Your Engine

1. Turn your ignition key to RUN. Observe the WAIT TO START light. (This light may

not come on if the engine is hot.)

2. As soon as the WAIT TO START light goes off, IMMEDIATELY turn the ignition key to START. When the engine starts, let go of the key.

NOTICE:

Don’t try to shift to PARK (P) if your vehicle is moving. If you do, you could damage the transmission. Shift to PARK (P) only when your vehicle is stopped.

Manual Transmission

Move your shift lever to NEUTRAL and hold the clutch pedal to the floor while starting the engine. Your vehicle won’t start if the clutch pedal is not all the way

-- that’s a safety feature.

down

2-2

Holding your key in START for longer than 15 seconds at a time will cause your battery to be drained much sooner. And the excessive heat can damage your starter motor.

NOTICE:

If the WAIT TO START light stays on, it means that your vehicle could have one of several problems, so you should have it serviced right away.

3. If the engine does not start after 15 seconds of cranking, turn the ignition key to OFF. Wait one minute for the starter to cool, then try the same steps again.

If you’re trying to start your engine after you’ve run out of fuel, follow the steps in “Running Out of Fuel.” See “Diesel Fuel Requirements and Fuel System” in the Index.

When your engine is cold, let it run for a few minutes before you move your vehicle. This lets oil pressure build up. Your engine will sound louder when it’s cold.

NOTICE:

If you’re not in an idling vehicle and the engine overheats, you wouldn’t be there to see the coolant temperature gage. This could damage your vehicle. Don’t let your engine run when you’re not in your vehicle.

Cold Weather Starting (Diesel Engine)

The following tips will help you get good starting in cold weather.

Use the recommended engine oil when the outside temperature drops below freezing. See “Engine Oil” in the Index. When the outside temperature drops below 0_F ( is recommended.

See “Diesel Fuel Requirements and Fuel System” in the Index for information on what fuel to use in cold weather.

If Your Diesel Engine Won’t Start

If you’ve run out of fuel, look at “Running Out of Fuel.” See “Diesel Fuel Requirements and Fuel System” in the Index.

If you’re not out of fuel, and your engine won’t start, do this:

Turn your ignition key to RUN. IMMEDIATELY after the WAIT TO START light goes off, turn the ignition key to START.

If the light doesn’t go off, wait a few seconds, then try starting your engine again. And, see your dealer as soon as you can for a starting system check.

If the light comes on and then goes off and you know your batteries are charged, but your engine still won’t start, your vehicle needs service.

If the light does not come on when the engine is cold, your vehicle needs service.

If your batteries don’t have enough charge to start your engine, see “Battery” in the owner’s manual.

Be sure you have the right oil for your engine, and that you’ve changed the oil at the proper times. If you use the wrong oil, your engine may be harder to start.

If the engine starts, runs a short time, then stops, your vehicle needs service.

CAUTION:

Do not use gasoline or starting “aids,” such as ether, in the air intake. They could damage your engine. There could also be a fire, which could cause serious personal injury.

Engine Coolant Heater

In very cold weather, 0_F (-18_C) or colder, the engine coolant heater can help. You’ll get easier starting and better fuel economy during engine warm the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle.

To Use the Engine Coolant Heater

1. Turn off the engine.

2. Open the hood and unwrap the electrical cord. The cord is located on the passenger’s side of the engine compartment, near the right side engine mount.

3. Plug it into a normal, grounded 110

CAUTION:

Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three 110

-volt AC outlet. If the cord won’t reach,

use a heavy rated for at least 15 amps.

4. Before starting the engine, be sure to unplug and store the cord as it was before to keep it away from moving engine parts. If you don’t, it could be damaged.

Warning Lights, Gages and Indicators

This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them.

Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to your warning lights and gages could also save you or others from injury.

Warning lights come on when there may be or is a problem with one of your vehicle’s functions. As you will see in the details on the next few pages, some warning lights come on briefly when you start the engine just to let you know they’re working. If you are familiar with this section, you should not be alarmed when this happens.

Gages can indicate when there may be or is a problem with one of your vehicle’s functions. Often gages and warning lights work together to let you know when there’s a problem with your vehicle.

When one of the warning lights comes on and stays on when you are driving, or when one of the gages shows there may be a problem, check the section that tells you what to do about it. Please follow this manual’s advice. Waiting to do repairs can be costly dangerous. So please get to know your warning lights and gages. They’re a big help.

Your vehicle may also have a message center that works along with the warning lights and gages. See “Message Center” in the Index.

Malfunction Indicator Lamp (Service Engine Soon Light) (Check Engine Light)

United States Canada

NOTICE:

If you keep driving your vehicle with this light on, after a while, your emission controls may not work as well, your fuel economy may not be as good and your engine may not run as smoothly. This could lead to costly repairs that may not be covered by your warranty.

Your vehicle is equipped with a computer which monitors operation of the fuel, timing and emission control systems.

This system is called OBD II (On Diagnostics to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The SERVICE ENGINE SOON light comes on to indicate when service is required. Malfunctions often will be indicated by the system before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction.

-Second Generation) and is intended

-Board

2-8

NOTICE:

Modifications made to the engine, transmission, exhaust, intake or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission controls and may cause the SERVICE ENGINE SOON or CHECK ENGINE light to come on. Modifications to these systems could lead to costly repairs not covered by your warranty. This may also result in a failure to pass a required Emission Inspection/Maintenance test.

If the Light Comes On

This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If it doesn’t, have it repaired. This light will also come on if an emission control system malfunction has been detected on your vehicle. Dealer or qualified service center diagnosis and service may be required.

You also may be able to correct the emission system malfunction by considering the following:

Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition

will usually be corrected when the electrical system dries out. A few driving trips should turn the light off.

Are you low on fuel? As your engine starts to run out of fuel, your engine may

not run as efficiently as designed since small amounts of air are sucked into the fuel line. The system can detect this. Adding fuel should correct this condition. It will take a few driving trips to turn the light off.

If none of the above steps have made the light turn off, have your dealer or qualified service center check the vehicle. Your dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that may have developed.

Emissions Inspection and Maintenance Programs

Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration.

Here are some things you need to know in order to help your vehicle pass an inspection.

Your vehicle will not pass this inspection if the SERVICE ENGINE SOON or CHECK ENGINE light is on or not working properly.

Your vehicle will not pass this inspection if the OBD (on critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, see your dealer or qualified service center to prepare the vehicle for inspection.

Wait To Start Light

Fuel Gage

Your diesel engine has a glow plug system to aid in starting your vehicle.

An instrument panel WAIT TO START light shows that the system is functioning properly and tells you when the engine is ready to be started.

For more information, see “Starting Your Diesel Engine” in the Index.

When the ignition is on, the fuel gage shows you approximately how much fuel you have left in your tank.

The gage will first indicate E (Empty) before you are out of fuel, but you should get more fuel as soon as possible.

2-10

Listed are four situations you may experience with your fuel gage:

At the gas station, the fuel pump shuts off before the gage reads F (Full).

It takes a little more or less fuel to fill up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to fill the tank.

The gage moves a little when you turn a corner or speed up.

The gage doesn’t go back to E (Empty) when you turn off the ignition.

None of these indicate a problem with the fuel gage. For information on how to fill your fuel tank, see “Fuel,

Filling Your Tank” in the Index. For your fuel tank capacity, see “Fuel, Tank Capacity”

in the Owner’s Manual. Your vehicle also has a fuel cooler. To clean, power

wash the bottom of the vehicle.

Message Center

The message center is located above the transmission temperature gage (if equipped) on the instrument panel cluster. It gives you important safety and maintenance facts. When you turn the ignition on, the entire center lights up for just a few seconds. (The battery display will stay on while the key is in RUN until the engine is started.)

2-11

Reduced Engine Power

Water in Fuel

On diesel engines, a computer monitors the operation of the electronic accelerator.

If this message comes on while you are driving, the computer is indicating that your vehicle has a problem. You should take your vehicle in for service soon.

This light will come on to warn you if there is water in the diesel fuel system.

For more information on how this message works, see “Diesel Fuel Requirements and Fuel System” in the Index.

Engine Overheating

You will find a coolant temperature gage on the instrument cluster. In addition, the message center has the following warnings that may appear. LOW COOLANT, CHECK COOLANT TEMP and ENGINE OVERHEATED. See your owner’s manual for more information.

If Steam Is Coming From Your Engine

CAUTION:

Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood.

If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool.

NOTICE:

If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty.

5-2

If No Steam Is Coming From Your Engine

If you get an engine overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you:

Climb a long hill on a hot day.

Stop after high

Idle for long periods in traffic.

T ow a trailer. See “Driving on Grades” in the Owner’s Manual.

If you get the overheat warning with no sign of steam, try this for a minute or so:

1. If you have an air conditioner and it’s on, turn it off.

2. Turn on your heater to full hot at the highest fan speed and open the window as necessary.

3. If you’re in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear while driving -- DRIVE (D).

-speed driving.

If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning doesn’t come back on, you can drive normally.

If the warning continues, pull over, stop, and park your vehicle right away.

If there’s still no sign of steam, push down the accelerator until the engine speed is about twice as fast as normal idle speed for at least three minutes while you’re parked. If you still have the warning, turn off the engine and get everyone out of the vehicle until it cools down.

You may decide not to lift the hood but to get service help right away.

5-3

Cooling System (Diesel Engine)

When you decide it’s safe to lift the hood, here’s what you’ll see:

A. Coolant Surge Tank B. Coolant Surge Tank Pressure Cap C. Engine Fan If the coolant inside the coolant surge tank is boiling,

don’t do anything else until it cools down.

When the engine is cold, the coolant level should be at or above the FILL COLD mark. If it isn’t, you may have a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.

CAUTION:

Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned.

Don’t run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.

NOTICE:

How to Add Coolant to the Coolant Surge Tank

Engine damage from running your engine without coolant isn’t covered by your warranty.

NOTICE:

When adding coolant, it is important that you use only DEX

If coolant other than DEX-COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner 30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX not covered by your new vehicle warranty.

If there seems to be no leak, start the engine again. See if the engine cooling fan speed increases when idle speed is doubled by pushing the accelerator pedal down. If it doesn’t, your vehicle needs service. Turn off the engine.

NOTICE:

The diesel engine has a specific coolant fill procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged.

If you haven’t found a problem yet, but the coolant level isn’t at or above the FILL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. See “Engine Coolant” in the Index for more information.

5-5

CAUTION:

Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge tank pressure cap can come out at high speed. Never turn the cap when the cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap.

CAUTION:

NOTICE:

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixtur e, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX

coolant.

In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. So use the recommended coolant.

CAUTION:

You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine.

1. You can remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise (left) about one full turn. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.

If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.

2. Then keep turning the pressure cap slowly, and remove it.

3. After the engine cools, open the air bleed valve on the thermostat housing.

CAUTION:

You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine.

4. Fill with the proper mixture. Add coolant until you see a steady stream of coolant coming from the bleed valve.

5. Close the bleed valve.

6. Rinse or wipe the spilled coolant from the engine and compartment.

7. Then fill the coolant surge tank with the proper mixture, to slightly above the fill mark.

5-9

8. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan.

By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the FILL COLD mark.

Diesel Engine Fuel

NOTICE:

Diesel fuel or fuel additives not recommended in this manual could damage your fuel system and engine. Your warranty wouldn’t cover this damage. And:

Diesel fuel that has been mixed with engine oil could damage your engine and emission controls. Check with the service station operator to make sure the diesel fuel has not been mixed with engine oil.

If you ever run out of diesel fuel, it can be difficult to restart your engine. “Running Out of Fuel,” later in this section, tells you how to get it started again. To avoid all this, never let your tank get empty.

6-2

What Fuel to Use

In the United States, for best results use Number 2-D diesel fuel year conditions) as oil companies blend Number 2 address climate differences. Number 1 may be used in very cold temperatures (when it stays below 0_F or -18_C); however, it will produce a power and fuel economy loss. Avoid the use of Number 1 diesel fuel in warm or hot climates. It may result in stalling, poor starting when the engine is hot and may damage the fuel injection system.

At a minimum, the diesel fuel you use should meet specifications ASTM D975 the United States. In addition, the Engine Manufacturers Association (EMA) has identified properties of an improved diesel fuel for better engine performance and durability. Diesel fuels corresponding to the EMA Recommended Guideline on Premium Diesel Fuel (FQP-1A) could provide better starting, less noise and better vehicle performance. If there are questions about the fuel you are using, please contact your fuel supplier.

Diesel fuel may foam when you fill your tank. This can cause the automatic pump nozzle to shut off, even though your tank isn’t full. If this happens, just wait for the foaming to stop and then continue to fill your tank.

CAUTION:

Heat coming from the engine may cause the fuel to expand and force the fuel out of your tank. If something ignites the fuel, a fire could start and people could be burned. To help avoid this, fill your fuel tank only until the automatic nozzle shuts off. Don’t try to “top it off.”

Very Cold Weather Operation

Follow the instructions listed previously under the heading “What Fuel to Use.”

NOTICE:

Never use home heating oil or gasoline in your diesel engine. They can cause engine damage.

In cold weather, your fuel filter may become clogged (waxed). T o unclog it, move the vehicle to a warm garage area and warm the filter to between 32_F and 50_F (0_C to 10_C). You won’t need to replace it. Additional information on the fuel filter follows.

Water in Fuel

CAUTION:

Diesel fuel containing water is still flammable. You could be burned. If you ever try to drain water from your fuel, keep sparks, flames and smoking materials away from the mixture.

NOTICE:

If there is water in your diesel fuel and the weather is warm or humid, fungus and bacteria can grow in the fuel. They can damage your fuel system. You’ll need a diesel fuel biocide to sterilize your fuel system. Your dealer can advise you if you ever need this.

If your fuel tank needs to be purged to remove water, see your dealer or a qualified technician. Improper purging can damage your fuel system.

Sometimes, water can be pumped into your fuel tank along with your diesel fuel. This can happen if a service station doesn’t regularly inspect and clean its fuel tanks, or if it gets contaminated fuel from its suppliers.

If this happens, a WATER IN FUEL light will come on. If it does, the water must be drained. Your dealer can show you how to do this.
