2008 CHEVROLET KODIAK stop start

During this warm-up period, check your 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 3-37for
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 3-35for 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 3-32for 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 3-46for 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 3-30for more information.
•The voltmeter charge indicator gage tells you the
condition of your 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 3-31for more
information.
Notice:Do not allow the engine to operate at low
idle for more than ve 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.

Eaton®Fuller®Nine and Ten-Speed
Non-Synchronized Manual
Transmissions
If your vehicle has one of these transmissions the
engine rpm and road speed must match when upshifting
and downshifting. The label above the windshield will
tell you the operating basics you need to know.
The following are driving tips.
•Always choose an initial starting gear suitable for
the load and terrain.
•Always use double-clutching procedures when
shifting.
•Never move the range shift lever to the LO speed
gear position after HI range preselection, or
anytime the transmission is in the HI range.
•Never move the range knob or lever with the shift
lever in NEUTRAL while the vehicle is moving.
•Never make a range shift while moving in
REVERSE (R).
Clutch Brake (Vehicles with
Non-Synchronized Transmission)
A clutch brake is used to stop transmission input shaft
rotation so that FIRST (1) or REVERSE (R) gear
selection can be initiated when the vehicle is at a
standstill and the engine is idling.
Press the clutch pedal all the way down to the floorboard
to apply the clutch brake.
When using the clutch brake, disengage the clutch
pedal and shift the transmission into either the initial
starting gear or REVERSE (R). If the tooth-butting
occurs between the clutching teeth, re-engage the clutch
while applying light pressure to the shift lever. This
will provide for a smooth shift into either FIRST (1) or
REVERSE (R) gear.
Notice:Using the clutch brake for shifting into any
gear other than FIRST (1) or REVERSE (R) may
cause premature wear of the clutch brake and make
gear shift effort more difficult. Do not use the
clutch brake for shifting after engaging FIRST (1) or
REVERSE (R).
2-31

Shifting Out of Four-Wheel Low
To shift from Four-Wheel Low to Four-Wheel High or
Two-Wheel High, your vehicle must be stopped or
moving less than 3 mph (5 km/h) with the transmission in
NEUTRAL (N) and the engine running. The preferred
method for shifting out of Four-Wheel Low is to have your
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 ashing could damage the transfer
case. To help avoid damaging your vehicle, always
wait for the Four-Wheel High or Two-Wheel High
indicator light to stop ashing before shifting
the transmission into gear.
If the knob is turned to Four-Wheel High or Two-Wheel
High while your 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 your vehicle is moving less than 3 mph (5 km/h)
with the transmission in NEUTRAL (N).
Shifting Into NEUTRAL
Before shifting the transfer case to 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 NEUTRAL (N).
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 NEUTRAL indicator light comes on.
6. Shift the transmission to REVERSE (R) for
one second, then shift the transmission to
DRIVE (D) for one second.
7. Turn the ignition to OFF.
8. Place the transmission shift lever in PARK (P).
9. Turn the ignition to LOCK.

To set the foot pedal parking brake, hold the regular
brake pedal down with your right foot. Push down
the parking brake pedal with your left foot.
{CAUTION:
It can be dangerous to get out of your vehicle
without the parking brake rmly set. Your
vehicle can roll. If you have left the engine
running, the vehicle can move suddenly. You or
others could be injured. To be sure your vehicle
will not move, even when you are on fairly level
ground, always set the parking brake.
To set the hand lever parking brake, hold the regular
brake pedal down with your right foot. Pull up on
the handle with your right hand, until it stops.If the ignition is on when the parking brake is set, the
brake system warning light will come on.
Once the parking brake is applied, slowly remove your
foot from the regular brake pedal, while checking to
see if the vehicle moves. If the vehicle does start
to move, press the regular brake pedal and adjust the
parking brake holding force. See “Parking Brake
Adjustment” later in this section.
If the parking brake still does not set, take the vehicle to
your dealer/retailer for service.
To release the foot pedal parking brake, hold the
regular brake pedal down. Pull the brake release handle,
located just above the parking brake pedal.
To release the hand lever parking brake, hold the
regular brake pedal down and push down on the handle
until it stops.
If the ignition is on when the parking brake is released,
the brake system warning light will go off.

{CAUTION:
During DPF regeneration, the exhaust system
and exhaust gases are very hot. Things that
burn could touch hot exhaust parts under your
vehicle and ignite. You or others could be
burned. Do not park near or over papers, leaves,
dry grass, or other things that can burn.
When the yellow DPF indicator comes on, the filter is
dirty and DPF regeneration is necessary. When
driving continues without regeneration, the DPF indicator
will change from yellow to red. Continuing to drive the
vehicle with the red indicator can cause filter damage.
To clean the filter, either drive the vehicle above
30 mph (50 km/h) to activate the automatic regeneration
or stop the vehicle and perform the manual regeneration
procedure. For the automatic regeneration, drive until
the green DPF indicator light goes off. This will take
approximately 20 minutes. Once automatic regeneration
has started, drive until the green indicator light goes
off to complete the regeneration in a single operation if
possible.During regeneration, the
green DPF indicator light
will come on. See
Diesel Particulate Filter
Warning Light on
page 3-45.
Notice:Extended idle should be avoided because
the DPF system is not capable of automatically
regenerating at idle. During extended idle, be sure
to watch for the DPF indicator lights which could
come on to indicate that the DPF is becoming
full and needs regeneration. If the yellow or red
indicator light comes on, perform manual
regeneration or drive the vehicle as described
previously for automatic regeneration to clean the
lter. Continued engine operation with the yellow or
red DPF indicator light on, without performing
manual or automatic regeneration, could cause
irreversible damage to the DPF requiring repair and
possible replacement that might not be covered
by your warranty.
Extended idling can cause exhaust parts and gases to
become very hot. Keep the exhaust area clear of
material that could ignite or burn. SeeParking Over
Things That Burn on page 2-44for more information.
2-47

For vehicles with Power Take-Off (PTO), monitor the
instrument panel cluster for lights related to the DPF.
All engines consume some amount of engine oil. This is
normal. The by-product of combustion of engine oil is
ash. The ash will become trapped in the DPF over
the life of the vehicle. Eventually, the buildup of ash will
restrict the exhaust gases and the DPF will need to
be cleaned or replaced.
SeeAccessories and Modifications on page 5-4for
important information.
Manual Regeneration Procedure
{CAUTION:
During DPF regeneration, the exhaust system
and exhaust gases are very hot. Stay clear of
the tailpipe area and do not park over things
that burn. You or others could be burned or
your vehicle could catch re. SeeParking Over
Things That Burn on page 2-44.If the yellow or red DPF indicator is on, you can clean
the DPF by performing a manual regeneration.
When it is safe to do so, stop the vehicle. Perform
manual DPF regeneration in a well ventilated area.
Manual DPF regeneration must be performed outdoors,
as follows. Once manual regeneration is started,
complete the regeneration in a single operation if
possible. If manual regeneration is not completed, as
indicated by the green DPF indicator going off, and the
yellow or red indicator light remains on, automatic
regeneration might not be allowed until the vehicle is
stopped and manual regeneration is performed
until completed.
1. Check engine oil and engine coolant levels to be
sure they are at proper operating levels.
2. To prevent running out of fuel during regeneration,
make sure there is at least a quarter of a tank
of fuel.
3. Check to make sure the area near the exhaust
tailpipe and under the exhaust system are clear
of any materials that could catch fire. Keep people
away from the area of the exhaust system and
exhaust gases.

Windshield Wipers
You control the windshield
wipers by turning the band
with the wiper symbol on it.
9(Off):Turn the band on the lever to this symbol to
turn off the windshield wipers.
8(Mist):For a single wiping cycle, turn the band to
this symbol. Hold it there until the wipers start, then
let go. The wipers will stop after one cycle. If you want
more cycles, hold the band on mist longer.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain
or snow. Turn the band to select the delay time.
The farther the band is turned upward, the longer the
delay will be. The farther the band is turned downward,
the shorter the delay will be.For steady wiping at low speed, turn the band toward
you to the first solid band below the delay settings.
For high-speed wiping, turn the band farther, to the
last solid band below the delay settings. To stop
the wipers, move the band to off.
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
carefully loosen or thaw them. If your blades do
become worn or damaged, get new blades or blade
inserts. For more information, seeWindshield Wiper
Blade Replacement on page 5-76.
Heavy snow or ice can overload your wipers.
The windshield wiper motor is protected from overload
by a circuit breaker and a fuse. If the motor overheats
due to heavy snow or ice the wiper will stop until
the motor cools. Although the circuit is protected from
electrical overload, overload due to heavy snow or
ice may cause wiper linkage damage. Always clear ice
and heavy snow from the windshield before using
your windshield wipers.

Parking Brake Warning Light
Your vehicle has a brake warning light. When the
ignition is on, this light will come on when you set your
parking brake. The light will stay on if your parking
brake does not release fully.
This light should also come on when you turn the
ignition key to START. If it does not come on then, have
it fixed so it will be ready to remind you if the parking
brake is applied or has not released fully.
Air Brake System Warning Light
Vehicles with air brake systems have a brake system
warning light on the instrument panel.
The low air warning light
should come on, as a
check, whenever you start
the engine.
However, it is designed to come on, and stay on, when
brake reservoir pressure has dropped below 60 psi
(410 kPa).When the warning light comes on while you are driving,
you should drive only as far as the nearest point of
safety and then stop the vehicle. Here is a very
important thing for you to know:
{CAUTION:
If the air brake system warning light comes on
and the warning tone sounds, the vehicle can
stop suddenly and without further warning.
This is because the parking brake will come on
if the pressure falls below 35 to 45 psi (240 to
310 kPa). You or others could be injured. If the
air brake system warning light comes on and
the warning tone sounds, stop as soon as you
can. You will not know how quickly the system
is losing pressure, so be aware that the
parking brake may come on suddenly.
