ignition CHEVROLET KODIAK 2009 User Guide

Notice:If the wait to start light stays on after
starting the vehicle, the vehicle may not run
properly. Have the 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.
If you are trying to start the engine after you have run
out of fuel, seeRunning Out of Fuel on page 5-17.
When the engine is cold, let it run for a few minutes
before you move the vehicle. This lets oil pressure build
up. The 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
the vehicle. Do not let the engine run when you are
not in the vehicle.
Cold Weather Starting
If the vehicle has the 6.6L DURAMAX®Diesel Engine or
the Isuzu 6H Diesel Engine, the following notice applies:
Notice:The 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 fluid 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 fluid or you could
damage the engine. If you have the GM system, use
only GM approved starting fluid that has been tested
to establish compatibility with the air inlet heater
system.
The following tips will help with engine starting in cold
weather.
•Use the recommended engine oil when the outside
temperature drops below freezing. SeeEngine Oil
(DURAMAX Diesel Engine) on page 5-24or
Engine Oil (Caterpillar Diesel Engine) on page 5-27
orEngine Oil (Isuzu Diesel Engine) on page 5-28
orEngine Oil (Gasoline Engine) on page 5-32.
When the outside temperature drops below
0°F (−18°C), use of the optional 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 the optional engine coolant heater. See
Engine Coolant Heater on page 2-25.
•SeeWhat Fuel to Use on page 5-8for information
on what fuel to use in cold weather.

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, use of the proper engine oil,
optional engine coolant heater and optional ether
injection system 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, shift to N (Neutral).
Stopping the Diesel Engine
1. Apply the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
2. Shift into N (Neutral) for a manual transmission or
P (Park) for an automatic transmission.3. Turn the ignition key to OFF.
If the vehicle has a two-speed axle, seeTwo-Speed
Rear Axle on page 2-36.
If you have a Caterpillar
®diesel engine, see the
Caterpillar®Diesel Engine Operation & Maintenance
Manual for additional information.
Diesel Engine Warm-Up
Several factors affect how quickly the diesel engine
warms up. These can include outside temperature,
engine load, idle time and the vehicle’s option content.
The 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 the Caterpillar
®Operation & Maintenance manual
for additional diesel engine warm-up information.
2-16

If the Diesel Engine Will Not Start
If you have run out of fuel, seeRunning Out of Fuel on
page 5-17.
If you are not out of fuel, and the engine will not start,
do this:
Turn the ignition key to ON/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 the engine again. And, see your dealer/retailer
as soon as you can for a starting system check.
If the light comes on and then goes off and you know
the batteries are charged, but the engine still will
not start, the vehicle needs service.
If the light does not come on when the engine is cold,
the vehicle needs service.If the batteries do not have enough charge to start the
engine, seeBattery on page 5-61.
Be sure you have the right oil for the engine, and that
you have changed the oil at the proper times. If you use
the wrong oil, the 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, the
vehicle needs service.
{CAUTION:
Do not use gasoline or starting aids, such as
ether, in the air intake. They could damage the
engine. There could also be a fire, which could
cause serious personal injury.
2-17

The ENGINE SHUTDOWN WARNING LIGHT will come
on and a continuous chime will alert the driver
30 seconds before the engine goes into idle shutdown
mode. The engine shutdown warning light and chime will
stay on for the entire duration of the idle shutdown
event to inform the driver that the engine is in idle
shutdown mode. SeeEngine Shutdown Warning Light
on page 3-40for more information.
After the engine shutdown occurs, the engine is no
longer running, and the ignition is still in the ON/RUN
position, all accessories can be used. Turn the ignition
switch to START to restart the engine or turn it to
LOCK or OFF to prevent the battery from draining.High Idle System
High Idle System with Switch
If the vehicle has this
feature, the manual high
idle switch is located in the
instrument panel
switchbank.
2-20

This system can be used to increase the engine idle
speed whenever the following conditions are met:
•The brake pedal is not pressed.
•The vehicle is at a complete stop for vehicles with
diesel engines. The vehicle must not be moving
and the accelerator must not be pressed for vehicles
with gasoline engines.
•If the vehicle has manual transmission the clutch
pedal is not pressed or, if the vehicle has the
automatic transmission it is in N (Neutral) or
P (Park).
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/retailer may change the setting to fit
your needs.
For vehicles with Caterpillar
®diesel engines, the high
idle switch 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.
Automatic High Idle System
The automatic high idle feature will engage whenever
you start the vehicle and the engine is below the preset
operating temperature. This will help decrease engine
warm-up time.
On vehicles that have the Caterpillar
®diesel engine you
may have an exhaust restrictor that will operate in
High Idle mode. The exhaust brake switch must be on
for this feature to operate. SeeDiesel Engine Exhaust
Brake on page 2-26for more information.
Idle speed will then return to normal when the engine
reaches the preset operating temperature or has
been operating for at least 10 minutes.
2-21

Exhaust Restrictor (Engine
Warm-Up)
Exhaust Restrictor
If the vehicle has a Isuzu 6H Diesel Engine, it may have
a feature called an Exhaust Restrictor (NPE), which
uses an air actuated valve in the exhaust system
to restrict exhaust gas flow which enhances the engine
and heater warm-up.
Automatic Quick Warm-Up
If the vehicle has a DURAMAX®6600 engine, it has a
feature called an Automatic Quick Warm-Up, which uses
the turbocharger to restrict the exhaust gas flow
which enhances the engine and heater warm-up.
In both systems, exhaust restrictor or automatic quick
warm-up, the cold temperature high idle feature elevates
the engines idle speed, up to 1500 rpm, and restricts
the exhaust gas flow, when outside temperatures
are below 50°F (10°C), and the engine coolant
temperature is below certain levels. This feature
enhances heater performance by raising the engine
coolant temperature faster.For all engines this feature is already turned on. The
automatic quick warm-up on the DURAMAX
®engine
can be turned off and on by doing the following
procedure:
1. Turn the ignition to ON/RUN, with the vehicle off.
2. Press the accelerator pedal to the floor and
hold it while quickly pressing and fully releasing the
brake pedal three times in less than eight seconds.
3. Release the accelerator pedal and start the engine.
The green exhaust brake/restrictor light below the
radio controls will be lit for 10 seconds.
If this feature is turned off, by doing the procedure
described previously, and then the engine is
started, the exhaust brake/restrictor light will flash
for 10 seconds and then it will turn off.
When the engine is started, it will slowly increase 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.
2-22

During this warm-up period, check the warning lights
and gages:
•If oil pressure does not begin to rise within
15 seconds of starting, stop the engine and find the
cause. SeeOil Pressure Gage on page 3-38for
more information.
•If the engine coolant temperature gage needle goes
into the hot area on the gage, stop the engine and
find the cause of the overheating. SeeEngine
Coolant Temperature Gage on page 3-34for more
information.
•If you have air brakes, the dual-needle air pressure
gage should read at least 115 psi (790 kPa) for both
service systems before you try to move the vehicle.
When air pressure is below 60 psi (420 kPa), the
LOW AIR light will come on and you will hear a
tone alarm. SeeBrake System Warning Light on
page 3-31for more information. If the pressure does
not build up or drops during warm-up, stop the
engine and find the cause before you try to move the
vehicle. Recommended air pressure before driving is
120 psi (830 kPa). SeeAir Pressure Gage on
page 3-47for more information.
•The charging system light should come on when the
ignition key is turned to ON/RUN or START and
should go out when the engine is running above idle.
If the light does not go out or comes back on during
normal engine operation, have the charging system
checked right away. (This light tells you if the
generator is not charging; it does not reflect the
condition of the battery.) SeeCharging System Light
on page 3-29for more information.
•The voltmeter charge indicator gage tells you the
condition of the battery’s charge. The gage should be
in the center area during engine operation. The red
area on the left indicates an undercharge condition;
the red area on the right indicates an overcharge.
If the gage is in either red area, have the battery and
charging system checked right away. SeeVoltmeter
Gage on page 3-30for more information.
Notice:Do not allow the engine to operate at low
idle for more than five minutes. This can cause low
engine operating temperatures which can affect
engine operation and reduce engine life. Engine idle
speed should be increased to 1200 rpm whenever
extended idle is required. Once started, the engine
should be placed under load to allow the engine
coolant temperature to reach 150°F (66°C) before
shutting off the engine.

Locking Hubs
Turn the dial of the hublock (A) from the FREE position
to the LOCK position to lock the front axle.
Turn the dial of the hublock (A) from the LOCK position
to the FREE position to unlock the axle.
You do not have to back the vehicle up to disengage
the hublocks.If the vehicle has
four-wheel drive, the
transfer case knob is
located to the right of the
steering wheel on the
instrument panel. Use this
knob to shift into and
out of four-wheel drive.
An indicator light shows you which position the transfer
case is in. The indicator lights come on briefly when
you turn on the ignition and one stays on. If the lights do
not come on, you should take the vehicle to your
dealer/retailer for service. An indicator light flashes while
shifting the transfer case. It will remain on when the
shift is complete. If for some reason the transfer case
cannot make a requested shift, it returns to the last
chosen setting. Hublock Dial Location

Shifting Out of Four-Wheel Low
To shift from Four-Wheel Low to Four-Wheel High or
Two-Wheel High, the vehicle must be stopped or moving
less than 3 mph (5 km/h) with the transmission in
N (Neutral) with the engine running. The preferred
method for shifting out of Four-Wheel Low is to have
the vehicle moving 1 or 2 mph (1.6 to 3.2 km/h).
Turn the knob to Four-Wheel High or Two-Wheel High.
You must wait for the Four-Wheel High or Two-Wheel
High indicator light to stop flashing and remain on before
shifting the transmission into gear.
Notice:Shifting the transmission into gear before
the Four-Wheel High or Two-Wheel High indicator
light has stopped flashing could damage the transfer
case. To help avoid damaging the vehicle, always
wait for the Four-Wheel High or Two-Wheel High
indicator light to stop flashing before shifting
the transmission into gear.
If the knob is turned to Four-Wheel High or Two-Wheel
High while the vehicle is in gear and/or moving, the
Four-Wheel High or Two-Wheel high indicator light
flashes for 30 seconds. It will not complete the shift
unless the vehicle is moving less than 3 mph (5 km/h)
with the transmission in N (Neutral).
Shifting Into Neutral
Before shifting the transfer case to N (Neutral), first
make sure the vehicle is parked so that it will not roll.
1. Set the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
2. Start the vehicle.
3. Put the transmission in N (Neutral).
4. Shift the transfer case to Two-Wheel High.
5. Turn the transfer case knob all of the way past
Four-Wheel Low and hold it there for a minimum
of 10 seconds. The N (Neutral) indicator light
comes on.
6. Shift the transmission to R (Reverse) for
one second, then shift the transmission to D (Drive)
for one second.
7. Turn the ignition to OFF.
8. Place the transmission shift lever in P (Park).
9. Turn the ignition to LOCK.
2-34

Shifting Out of Neutral
To shift the transfer case out of N (Neutral), do the
following:
1. Set the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
2. Apply the regular brake pedal.
3. Turn the ignition to ON/RUN with the engine off.
4. Put the transmission in N (Neutral).
5. Turn the transfer case knob to the desired shift
position (Two-Wheel High, Four-Wheel High,
Four-Wheel Low).
6. After the transfer case has shifted out of N (Neutral),
the indicator light goes out.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
7. Release the parking brake.
8. Start the engine and shift the transmission lever to
the desired position.Excessively shifting the transfer case into or out of the
different modes can cause the transfer case to enter the
shift protection mode. This protects the transfer case from
possible damage and only allows the transfer case to
respond to one shift per 10 seconds. The transfer case
can stay in this mode for up to three minutes.
Parking
{CAUTION:
If you do not park the vehicle properly, it can roll.
If you have left the engine running, it can move
very quickly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on level ground, follow the steps below.
