2005 CHEVROLET KODIAK Owners Manual

Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not 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 will not start if the clutch pedal is not
all the way down — that is a safety feature.
Starting Your Engine
1. Turn your ignition key to RUN.
Observe the wait to start light. SeeWait to
Start Indicator (Diesel Engine) on page 3-36.
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.
If your vehicle is equipped with a DURAMAX
®6600
engine, it has a fast warm-up glow plug system.
The wait to start light will illuminate for a much
shorter time than most diesel engines, due to the
rapid heating of the glow plug system.
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 start light stays on after
starting your vehicle, your vehicle may not run
properly. Have your vehicle 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.
2-15

If you are trying to start your engine after you have run
out of fuel, seeRunning Out of Fuel on page 5-15.
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 is cold.
Notice:If you are not in an idling vehicle and
the engine overheats, you would not be there to
see the overheated engine indication. This could
damage your vehicle. Do not let your engine
run when you are not in your vehicle.
Cold Weather Starting
If your vehicle has the DURAMAX®Diesel Engine,
the following notice applies:
Notice:Your diesel engine has an electric air intake
heater system which reduces white smoke and helps
start the engine in cold weather. Do not spray
starting uid into the air intake where it can contact
the heater elements.If you do not have the GM Automatic Ether Injection
System, do not use starting uid or you could
damage your engine. If you have the GM system,
use only GM approved starting uid that has been
tested to establish compatibility with the air inlet
heater system.
The following tips will help you get good starting in
cold weather.
•Use the recommended engine oil when the outside
temperature drops below freezing. SeeEngine Oil
(Caterpillar
®Diesel Engine) on page 5-22or
Engine Oil (DURAMAX®Diesel) on page 5-22or
Engine Oil (Gasoline Engine) on page 5-26.
When the outside temperature drops below
0°F (−18°C), use of the optional engine coolant
block 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 optional engine coolant block heater.
SeeEngine Coolant Heater on page 2-24.
•SeeWhat Fuel to Use on page 5-8for information
on what fuel to use in cold weather.
2-16

Cold Weather Starting
(Caterpillar®Diesel)
Because the diesel engine uses compression ignition,
it is harder to start in cold weather than a gasoline
engine. The air intake heater and use of the proper
engine oil, optional engine coolant heaters and optional
ether injection systems help cold weather starting.
See the Caterpillar
®Diesel Engine Operation &
Maintenance Manual for more information.
Restarting the Diesel Engine While
Moving (Automatic Transmission)
If you have to restart the engine while the vehicle is
moving, you will first have to shift to NEUTRAL (N).
This safety feature prevents starting the engine when
the transmission is in a drive gear for more information.
Stopping the Diesel Engine
1. Set the parking brake and shift to NEUTRAL (N)
or PARK (P).
2. Turn the ignition key to OFF.
If your vehicle has a two-speed axle, see
Two-Speed Rear Axle Electric Shift Control on
page 2-26.
If you have a Caterpillar
®diesel engine, see your
Caterpillar®Diesel Engine Operation & Maintenance
Manual for additional information.
Diesel Engine Warm-Up
Several factors affect how quickly your diesel engine
warms up. These can include outside temperature,
engine load, idle time and your vehicle’s option content.
Your vehicle may be equipped with some features
that can help the engine reach operating temperature
sooner. Some of these features are discussed below.
Also, remember that an automatic transmission
adds heat to the cooling system through the heat
exchanger in the radiator. Because of this, vehicles
equipped with automatic transmissions are often able to
retain engine coolant heat better than manual
transmission vehicles.
See your Caterpillar
®Operation & Maintenance manual
for additional diesel engine warm-up information.
2-17

If Your Diesel Engine Will Not Start
If you have run out of fuel, seeRunning Out of Fuel on
page 5-15.
If you are not out of fuel, and your engine will not 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 does not 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 will not
start, your vehicle needs service.
If the light does not come on when the engine is cold,
your vehicle needs service.
If your batteries do not have enough charge to start
your engine, seeBattery on page 5-55.
Be sure you have the right oil for your engine, and that
you have 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. SeeWhat Fuel to Use on page 5-8.
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 re, which
could cause serious personal injury.
Engine Alarm and Automatic
Shutdown
Your check gages warning light will come on if the
system senses high engine temperature or low engine
oil pressure. If high engine temperature or low engine oil
pressure is detected, you will also hear a tone alarm
at two beats per second. The alarm and the light
will remain on until the condition is fixed. If the engine
temperature or oil pressure condition worsens, the
tone alarm will go to five beats per second.
2-18

If the system senses low engine coolant, the five beat
per second alarm and the low coolant warning light
will come on.
The five beats per second tone alarm means that your
engine will shut down in about 25 to 30 seconds.
There is also an engine shutdown light to indicate that
the engine will shut down. SeeEngine Shutdown
Warning Light on page 3-39.
Pull off the road and shut off the engine. Do not start it
until the reason for the problem is known, and the
problem is fixed. If the engine shuts down when you are
still in traffic, you can restart the engine and get
another 25 to 30 seconds of operation. Do this only if
you have to, since there is a problem that can harm the
engine if it is not fixed. Engine automatic shutdown,
for gasoline engines, requires activation by your dealer.
Notice:If you try to operate the vehicle after the
engine automatically shuts down, you may damage
the vehicle. Have your vehicle repaired as soon
as possible.High Idle System
(Caterpillar
®Diesel/Gasoline Engine)
Automatic High Idle System
(Diesel Engines)
The automatic high idle feature will engage whenever
you start your vehicle and the engine is below the preset
operating temperature. This will help decrease engine
warm-up time.
Idle speed will then return to normal under any of the
following conditions:
•The engine reaches the preset operating
temperature or has been operating for at least
10 minutes.
•The brake pedal is pressed.
•The manual transmission clutch pedal is pressed
or, the automatic transmission (if equipped) is
shifted from NEUTRAL (N) or PARK (P).
•The vehicle speed exceeds about 5 mph (8 km/h).
•The throttle is pressed.
2-19

Manual High Idle System
If your vehicle has this
feature, the manual high
idle switch is located in
the instrument panel
switchbank.
This system can be used to increase your engine idle
speed whenever the following conditions are met:
•The brake pedal is not pressed.
•The vehicle speed is below about 5 mph (8 km/h)
for vehicles with diesel engines. The vehicle must
not be moving and the accelerator must not be
pressed for vehicles with gasoline engines.
•The manual transmission (if equipped) clutch pedal
is not pressed or, the automatic transmission
(if equipped) is in NEUTRAL (N) or PARK (P).The manual high idle feature is activated by pressing
the switch on the instrument panel. When the switch is
pressed again, or any of the previous conditions are
not met, manual high idle will be deactivated.
The manual high idle has been preset at the factory.
Your dealer may change the setting to fit your needs.
For vehicles with Caterpillar
®diesel engines, manual
high idle can be used to set any desired high idle speed.
To set a new temporary engine idle speed do the
following:
1. Make sure all of the previously described
conditions are met.
2. Press the accelerator pedal to the desired
engine speed.
3. Momentarily press the manual high idle switch.
The temporary high idle speed will be set. This new high
idle rpm level will be remembered by the system until
either the ignition is turned to OFF or a new high idle
speed is set.
2-20

Exhaust Restrictor
(DURAMAX
®Diesel)
If your vehicle is equipped with a DURAMAX®6600
engine, it has a cold temperature high idle feature which
elevates the engines idle speed from 660 to 1500 rpms,
and restricts the exhaust gas flow, when outside
temperatures are below 32°F (0°C), and the engine
coolant temperature is below 150°F (65°C). This feature
enhances heater performance by raising the engine
coolant temperature faster.
This feature is already turned on. This feature can be
turned off and on by doing the following brake stomp
procedure:
1. Turn the ignition to RUN, with the vehicle off.
2. Press the accelerator pedal to the floor and
hold while quickly pressing the brake pedal
three times in less than eight seconds.
3. Release the accelerator pedal and start
the engine.If this feature is turned on when the engine is started,
the green exhaust brake/restrictor light below the
radio controls will be lit for 10 seconds. If this feature is
turned on and the algorithm comes on, based upon
the temperature conditions and other conditions, then
the green exhaust brake/restrictor light will remain lit and
the engine will slowly ramp up to the high idle speed
after a delay of a few seconds up to approximately
two minutes.
When the engine is started, it will slowly ramp up to the
high idle speed after a delay of a few seconds up to
about two minutes. For this method to work properly
there must be no throttle or brake pedal faults, and the
throttle pedal must not fall below 75 percent of wide
open throttle while pressing the brake pedal.
The engine idle speed will return to normal once the
following conditions are met:
•Once engine coolant temperature reaches
150°F (65°C).
•Air intake temperature reaches 41°F (5°C).
2-21

The high idle speed will be temporarily interrupted and
the engine speed will return to normal if any of the
following conditions occur:
•The brake pedal is applied.
•The accelerator pedal is pressed.
•The automatic transmission is shifted out of
PARK (P) or NEUTRAL (N).
•The clutch pedal on the manual transmission is
pressed.
•Vehicle speed is detected.
Once these inputs are removed, the engine idle speed
will slowly ramp back up to high idle after the normal
delay, if the conditions for engine coolant temperature
and air intake temperature are still met.
If this feature is turned off, by doing the brake stomp
procedure described above, and then the engine
is started the exhaust brake/restrictor light will flash for
10 seconds and then it will turn off.
Engine Checks Before Operating
When you have started your engine, let it run for
20 to 30 seconds before you put a load on the engine.
But do not leave the vehicle while the engine is running.
Avoid unnecessary idling of diesel engine equipped
vehicles.
If the engine idles too long, the temperature of the
engine coolant will fall below the normal operating
range. Low engine operating temperature causes
several conditions which affect engine operation and
reduce engine life.
The engine should be permitted to go through a
warm-up period. Operate the vehicle at a minimum of
600 rpm during the warm-up period. During this
period and during operation, the following observations
should be made.
