Starting Your Diesel Engine

Your diesel engine starts differently than a

gasoline engine.

Automatic Transmission

Move your shift lever to PARK (P) or NEUTRAL (N).

Your engine won’t start in any other position -- that’s

a safety feature. To restart when you’re already moving,

use NEUTRAL (N) only.

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

down -- that’s a safety feature.

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:

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 STARTlight stays on, it meansthat

your vehicle could have one of several problems,

so you should have it serviced right away.

2-3

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 (-18

C), use of the engine coolant heater

is recommended.

If you experience longer cranking times, notice an unusual

amount of exhaust smoke or are at higher altitudes

(over 7,000 ft. or 2,135 m), you may use your engine

coolant heater. See “Engine Coolant Heater” in the Index.

See “Diesel Fuel Requirements and Fuel System”

in the Index for information on what fuel to use in

cold weather.

2-4

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.

Be sure you are using the proper fuel for existing

weather conditions. See “Diesel Fuel Requirements

and Fuel System” in the Index.

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 (If Equipped)

On 3500HD models, the engine coolant heater electrical

cord is located on the driver’s side of the engine

compartment, near the power steering reservoir.

On full-size van models, the cord for the engine coolant

heater is located on the driver’s side of the engine

compartment and is attached to the hose for the power

steering reservoir.

2-5

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-up. Usually,

the coolant heater should be plugged in a minimum of

four hours prior to starting your vehicle. At temperatures

above 32

F (0

C), use of the coolant heater is

not required.

To Use the Engine Coolant Heater

1. Turn off the engine.

2. Open the hood and unwrap the electrical cord.

3. Plug it into a normal, grounded 110-volt AC outlet.

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-prong

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

heavy-duty three-prong extension cord 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.

How long should you keep the coolant heater plugged

in? The answer depends on the outside temperature.

From 32

F to -10

F (0

C to -23

C), keep

the coolant heater plugged in at least two hours.

Below -10

F (-23

C), keep the coolant heater

plugged in for a minimum of eight hours or overnight.

It will not harm either the coolant heater or the vehicle

to leave the coolant heater plugged in longer than

the times stated. Be sure to remove and store the

cord before starting the engine. See “Diesel Fuel

Requirements and Fuel System” in the Index for

information on what fuel to use in cold weather.
