2009 CHEVROLET KODIAK warning light

{CAUTION:
If you apply any one of the air brake parking
controls while the vehicle is moving, the rig will
stop suddenly. If you are not ready for this, you or
others could be injured. Do not apply any one of
these controls while you are driving, unless you
have to make an emergency stop.
If the air pressure drops below 60 to 70 psi
(413 to 482 kPa), the primary brake warning light and
buzzer will come on. If the air pressure drops to
35 to 45 psi (241 to 310 kPa), the red trailer air supply
knob will automatically pop out and apply the spring
brakes on the trailer.
If the air pressure drops to 35 to 45 psi (241 to 310 kPa),
the yellow park brake knob will automatically pop out
and apply the spring brakes on the truck or tractor.
If you ever have a complete loss of air so that the air
brakes automatically apply, there is a way that the
tow operator can release the parking brakes to tow the
vehicle. SeeTowing Your Vehicle on page 4-23.
Parking Brake Burnish Procedure
All vehicles which have hydraulic brakes have a parking
brake. It is recommended that the parking brake be
burnished as part of the new vehicle break-in. The
parking brake will work best after it has been burnished
following these instructions:
1. Make sure that there is no other traffic around,
bring the vehicle speed up to 20 mph (32 km/h)
and apply the parking brake. Let the vehicle come
to a complete stop. Apply the base brakes and
disengage the parking brake.
2. Repeat the burnishing procedure in Step 1 a total
of 10 times.
3. Between stops, drive the vehicle about
2.5 miles (4 km).
Notice:Driving with the parking brake on can
damage the transmission and brake system parts.
Verify that the parking brake is fully released and the
brake warning light is off before driving.

Diesel Particulate Filter
The vehicle has a Diesel Particulate Filter (DPF) as part
of the exhaust system to reduce vehicle emissions. The
DPF requires a unique exhaust tailpipe with an exhaust
cooler. The exhaust cooler mixes air with the exhaust to
lower the temperature before it leaves the tailpipe.
The DPF, the tailpipe, or other exhaust system
components must not be altered. Inspect regularly and
clean any mud or dirt from the exhaust cooler,
especially where the exhaust cooler connects to the
tailpipe and the openings where fresh air enters
the cooler. See “Exhaust System Inspection” underAt
Least Twice a Year on page 6-27.
The DPF will clean itself as part of normal operation.
Several factors including fuel consumed, hours of engine
operation and miles driven are monitored by the Engine
Control Module (ECM). The self cleaning occurs
approximately once per tank of fuel.
During self cleaning, the
green DPF indicator light
will come on. See
Diesel Particulate Filter
Warning Light on
page 3-46.To clean the filter, either drive the vehicle above 30 mph
(50 km/h) to activate self cleaning, or stop the vehicle
and perform the manual cleaning procedure. For
self cleaning, drive until the green DPF indicator light
goes off. This will take approximately 20 minutes. Once
self cleaning has started, drive until the green indicator
light goes off to complete the cleaning in a single
operation if possible.
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.
{CAUTION:
During DPF self cleaning or during extended idling
in P (Park), the exhaust system and exhaust
gases are very hot. Things that burn could touch
hot exhaust parts under the vehicle and ignite.
You or others could be burned. Do not park, or
idle for an extended period of time, near or over
papers, leaves, dry grass, or other things that can
burn. Keep the exhaust area clear of material that
could ignite or burn. SeeParking Over Things
That Burn on page 2-44for more information.
2-46

Notice:Extended idle should be avoided because
the DPF system is not capable of self cleaning at
idle. During extended idle operation, monitor the
instrument panel telltale lights and Driver Information
Center for messages and take appropriate indicated
action. Continued idling with the warning light/
message on could cause irreversible damage to the
DPF requiring repair and possible replacement that
might not be covered by the vehicle warranty.
When the yellow DPF indicator comes on, the filter is
dirty and needs cleaning. You will also notice a change
in the exhaust sound and engine idle speed. This is
normal. If you continue to drive and the exhaust filter is
not cleaned as required, the DPF indicator will change
from yellow to red. Continuing to drive the vehicle
with the red indicator can cause filter damage.
Vehicles with DPF have specific fuel and engine oil
requirements. SeeWhat Fuel to Use on page 5-8and
Engine Oil (DURAMAX Diesel Engine) on page 5-24
orEngine Oil (Caterpillar Diesel Engine) on page 5-27or
Engine Oil (Isuzu Diesel Engine) on page 5-28or
Engine Oil (Gasoline Engine) on page 5-32for more
information on those requirements.Notice:Permanent damage can occur to the DPF
or related components if the required Ultra Low
Sulfur Diesel (15 ppm sulfur maximum) or low ash
CJ-4 engine oil is not used. This damage would
not be covered by the vehicle warranty.
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. Ash
is the by-product of engine oil consumption. 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 5-3for
important information if you are considering adding
accessories or modifying the vehicle.

Rear Heating System
If the vehicle has a crew
cab and has a rear heater,
the thumbwheel for this
feature is located on
the headliner.
To increase and decrease the flow of heated air to the
rear floor vents, turn the thumbwheel to the desired
fan speed. To turn the fan off, turn the thumbwheel all
the way down.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briefly when the engine is started
to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.
3-23

{CAUTION:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. For example, the right
front passenger airbag could inflate even though
the airbag on-off switch is turned off.
To help avoid injury to yourself or others, have the
vehicle serviced right away. SeeAirbag Readiness
Light on page 3-27for more information, including
important safety information.
If the word ON is lit, it means that the right front
passenger frontal airbag is enabled (may inflate). See
Airbag Off Switch on page 1-55for more on this,
including important safety information.
Charging System Light
The charging system light
may be located in the
instrument panel cluster, or
with the auxiliary warning
lights in the center of
the instrument panel.
It should come on briefly when you turn on the ignition,
before the engine is running, as a check to show
that it is working.
If it stays on, or comes on while you are driving, have
your vehicle checked right away. You could have a loose
generator drive belt or some other problem.
Driving while this light is on will drain your battery. If you
must drive a short distance with the light on, turn off
your radio and other accessories. Sustained driving with
a generator failure could result in a lack of back-up
braking if the engine quits or the power steering pump
should fail.
