2008 CHEVROLET KODIAK warning light

{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.

Rear Heating System
If you have a crew cab
and your vehicle 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
This part describes the warning lights and gages that may
be on your vehicle. The pictures will help you locate them.
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
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some warning
lights come on briefly when you start the engine just to let
you know they are working. If you are familiar with this
section, you should not be alarmed when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when there
is a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells
you what to do about it. Waiting to do repairs can
be costly and even dangerous.
3-24

{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could inate even though the switch is off.
If this ever happens, do not let anyone whom
the national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing child
restraint in the right front passenger’s seat)
until you have your vehicle serviced. See
Airbag Off Switch on page 1-56andAirbag
Readiness Light on page 3-28for more on this,
including important safety information.
If the word ON or the on symbol is lit, it means that
the right front passenger’s frontal airbag is enabled
(may inflate). SeeAirbag Off Switch on page 1-56for
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.
3-30

Voltmeter Gage
When your engine is
running, the voltmeter
gage shows the charging
system voltage.
Readings in either warning zone indicate a possible
problem in the electrical system.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system may not be able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself because higher engine
speeds allow the charging system to create maximum
power.
You can only drive a short time on the battery. Be sure
to shut off the radio, the fan or any unnecessary
accessories and have the system serviced.
Service Transmission Warning Light
If your vehicle has an Allison®automatic transmission,
certain transmission malfunctions will turn this light on.
This light is located with
the auxiliary warning lights
in the center of the
instrument panel.
If this light comes on while you are driving, do not use
the transmission shift control or you may lose forward
gears. The computer for the transmission senses
a problem and chooses a gear to stay in so that you
can drive the vehicle in that gear. You may not be able
to drive as fast or back up when this light is on.
Notice:If you continue driving your vehicle after the
transmission warning light comes on, you could
damage the transmission. While this light is on, the
transmission cannot operate in all gears. If you
attempt to shift gears, the vehicle may not continue
to move. Do not attempt to shift gears while the
transmission warning light is on. Instead, drive
directly to an authorized dealer for service. If you
cannot drive to a dealer immediately, have the
vehicle towed.
3-31

Range Inhibit Warning Indicator
If your vehicle has an Allison 1000/2200/2300/2500 series
automatic transmission, a lighted bar under the current
gear selected will flash.
If your vehicle has an Allison 3000/3500 series
automatic transmission, the current gear selected on
the pushbutton display will flash.
The flashing bar or gear selection indicates that
transmission range shifts may not occur.
For detailed information on shift inhibit limitations, see
the Allison Automatic Transmission Operator’s Manual in
your vehicle for further information.
Brake System Warning Light
Your vehicle has either hydraulic or air brakes.
Each system has different warning lights.
Hydraulic Brake System Warning Lights
Vehicles with hydraulic brake systems have two brake
system warning lights on the instrument panel.
If the brake warning light
comes on, it means that
the fluid level in the master
cylinder reservoir is low or
there is another problem
with your hydraulic brakes.
When it comes on, you will also hear a warning tone.
This light should come on briefly when you turn the
ignition key to RUN. If it does not come on, then have it
fixed so it will be ready to warn you if there is a problem.
The brake 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” underBraking on page 4-4.
