2007 CHEVROLET KODIAK stop start

•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 173for 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 169for 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 183for
more information.
•The charging system light should come on
when the ignition key is turned to 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 thegenerator is not charging; it does not reflect
the condition of the battery.) SeeCharging
System Light on page 167for 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 168
for 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.

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).
Power Take-Off (PTO)
If your vehicle is
equipped for the
addition of a PTO, this
factory installed
switch will be located in
the instrument panel.
When the PTO switch is in the ON position,
engine speed is limited to maximum PTO speed if
PTO is activated during driving; therefore
limiting overall vehicle speed.
Before using a PTO, refer to the manufacturer’s or
installer’s instructions.

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.
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.

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 316.
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.

The brake system warning light may come on, and
the warning tone may sound, when you are
turning and braking at the same time. This is
normal. See “Hydraulic Brake Systems” under
Braking on page 210.
This light is located
above the climate
controls in the center of
the instrument panel.
If the service brakes soon warning light comes on,
it means there may be something wrong in the
brake system.
When this light comes on, you will also hear a
warning tone. Have the system repaired
immediately.Both of these lights should come on briefly every
time you start your engine. If they do not come
on then, have them fixed so they will be ready to
warn you if there is a problem. If one or both
of these warning lights stay on after you start the
engine, there could be a brake problem. Have
your brake system inspected right away.
If one or both of these lights come on while you
are driving, pull off the road and stop carefully. You
may notice that the pedal is harder to push, or
the pedal may go closer to the floor. It may take
longer to stop. If this light is still on, have the
vehicle towed for service. SeeTowing Your
Vehicle on page 241. See “Hydraulic Brake
Systems” underBraking on page 210for further
information.

Parking Brake Warning Light
This light will also come on when you set the
parking brake. The light will stay on if your parking
brake does not release 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’s
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.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area,
your engine coolant might have overheated and
your engine may be too hot. You should pull off the
road, stop your vehicle and turn off the engine
as soon as possible.
SeeEngine Overheating on page 288. If you have
a Caterpillar
®diesel engine, also see your
Caterpillar®Operation & Maintenance Manual.
Low Coolant Warning Light
You have a low coolant
warning light. If this light
comes on, your system
is low on coolant and the
engine may overheat.
The warning light should come on briefly, as a
check, when you turn on the ignition.
When it comes on, you will also hear a warning
tone at several beats per second for 10 seconds.
SeeEngine Coolant (Gas and DURAMAX
®/Isuzu
Engines) on page 284orEngine Coolant
(Caterpillar
®Diesel Engines) on page 287and
have your vehicle serviced as soon as you can.
This light may also come on if your vehicle is
equipped with the automatic engine shutdown
system and engine shutdown has begun.
SeeEngine Alarm and Automatic Shutdownunder
Starting the Diesel Engine on page 100.

Playing a CD
Insert a CD partway into the slot, label side up.
The player pulls it in and the CD should begin
playing. CD appears on the display. If you want to
insert a CD with the ignition off, first press the
eject button or the RCL knob.
If you insert a CD with the radio off and the
ignition on, it starts to play.
If the ignition or radio is turned off, with a CD in
the player, it stays in the player. When the ignition
or radio is turned on, the CD starts playing
where it stopped, if it was the last selected audio
source.
As each new track starts to play, the track number
appears on the display.The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs
and the smaller CDs are loaded in the same
manner.
If playing a CD-R, the sound quality may be
reduced due to CD-R quality, the method of
recording, the quality of the music that has been
recorded, and the way the CD-R has been
handled. There may be an increase in skipping,
difficulty in finding tracks, and/or difficulty in loading
and ejecting. If these problems occur, check the
bottom surface of the CD. If the surface of the CD
is damaged, such as cracked, broken, or
scratched, the CD will not play properly. If the
surface of the CD is soiled, seeCare of Your CDs
on page 203for more information.
If there is no apparent damage, try a known
good CD.
