2008 CHEVROLET KODIAK Owners Manual

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.

Parking Brake Adjustment (Hand Lever
System Only)
Make sure the parking brake burnish procedure has
been previously followed before continuing with any park
brake adjustment. SeeParking Brake Burnish
Procedure on page 2-43for more information. Parking
brake adjustment may be necessary after the burnish
procedure or at the scheduled maintenance intervals.
If the vehicle is has a hand-lever park brake system, an
in-cab adjustment may be made to the park brake
system. This will adjust the parking brake holding force.
The adjustment is made with the knob located at the
end of the hand lever.
To make an adjustment:
1. Press and hold the regular brake pedal
2. Release the parking brake
3. Turn the knob only up to a half turn to the left, top
of knob toward the driver. This will increase the
holding force of the system.
2-40

4. Check to see if the vehicle moves by slowly
removing your foot from the regular brake pedal.
5. If the vehicle moves, press the regular brake and
repeat the adjustment procedure.
Notice:Over-tightening the park brake lever can
cause damage to the park brake system.
Over-tightening is possible by turning the knob
more than half a turn.
Over-tightening is similar to driving down the road with
your regular brakes applied. If your park brake system is
over-tightened your vehicle may seem sluggish to
accelerate, and/or your park brake hand lever maybe
very hard to pull up and apply the park brake.
If the park brake is over-tightened turn the knob to the
left until it stops and follow the parking brake adjustment
procedure.
Vehicles with a foot-pedal park brake system must be
serviced to make this adjustment. SeeScheduled
Maintenance on page 6-5for more information.Parking Brake (With Air Brakes)
If your vehicle has air
brakes, you will have this
parking brake. It is located
above the audio system in
the instrument panel.
Pulling it out applies the parking brake. The parking
brake light will come on when the air parking brake
is applied.
2-41

Vehicles built for use as tractors or towing vehicles have
two air brake controls. They look like this:
{CAUTION:
When the yellow PARKING BRAKE and the red
TRAILER AIR SUPPLY knobs are both pushed
in, your rig will be free to move. It could strike
someone or something. When both of these
knobs are pushed in, hold the regular brake
pedal down to keep your rig from moving.To charge a trailer’s air brake system do the following:
1. Move your vehicle into the proper position.
2. Apply the parking brake by pulling the yellow
parking brake knob out.
3. Hook up the trailer air system properly.
4. Get into the vehicle.
5. Push and hold down the regular brake pedal.
6. Push in both the yellow parking brake and the red
trailer air supply knobs. This will charge your
trailer’s air system.
After a few minutes, the trailer system should be fully
charged. When it is, the air pressure gage will show
about 125 to 135 psi (862 to 931 kPa). SeeAir Pressure
Gage on page 3-46for more information.
For driving with a trailer, the yellow and red, if equipped,
knobs must be pushed in. When you are not pulling a
trailer, the red trailer air supply knob must be pulled out.
2-42

{CAUTION:
If you apply any one of the air brake parking
controls while the vehicle is moving, your 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 light and warning
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 your 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 4-24.
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.

Air Suspension
Your vehicle may have the Hendrickson HAS Series
single-axle air suspension which is designed for a
single-axle on-highway use. This feature is available in
19,000 lb (8 613.3 kg), 21,000 lb (9 525.4 kg) and
23,000 lb (10 432.6 kg) capacities.
Rear Air Suspension Dump Control
If your vehicle is equipped with the Hendrickson
HAS Series single-axle air suspension, you may have
this control. The air suspension dump control allows the
operator to lower the deck height approximately
4.5 inches (11.5 cm) from the normal frame height.
The switch to deflate and
inflate the air suspension
is located on the
instrument panel.Press the bottom of the switch to deflate the air
suspension and lower the deck height. Press the top
of the switch to return the suspension to normal
deck height.
An indicator light will come on and stay on whenever
the switch is in the dumped position.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Do not
park over papers, leaves, dry grass, or other
things that can burn.
2-44

Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you cannot see
or smell. It can cause unconsciousness and
death.
You might have exhaust coming in if:
The exhaust system sounds strange or
different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a collision.
CAUTION: (Continued)
CAUTION: (Continued)

Your vehicle was damaged when driving
over high points on the road or over road
debris.
Repairs were not done correctly.
Your vehicle or the exhaust system has
been modied improperly.
If you ever suspect exhaust is coming into
your vehicle:
Drive it only with all the windows down to
blow out any CO; and
Have your vehicle xed immediately.
2-45

Diesel Particulate Filter (Diesel
Engine)
Your 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 at the tailpipe. This lowers the exhaust
temperature before it leaves the tailpipe.
The DPF, the tailpipe, or other exhaust system
components must not be altered. The area where the
exhaust cooler connects to the tailpipe should be
inspected, especially the area where the fresh air enters
the cooler. Make sure the openings are not restricted
or plugged with mud or dirt which could inhibit exhaust
gas cooling. See “Exhaust System Inspection” under
At Least Twice a Year on page 6-27.The DPF will regenerate (self-clean) itself as part of
normal operation. During regeneration, the green DPF
indicator is lit and you will notice a difference in
engine noise and engine speed, but this is normal. The
Engine Control Module (ECM) controls this function
based on several factors including the amount of fuel
consumed, hours of engine operation and miles driven.
Notice:Use of diesel fuel other than Ultra Low
Sulfur Diesel (15 ppm sulfur maximum) or engine oil
other than low ash CJ-4 oil will cause permanent
damage to the DPF and related components.
This damage would not be covered by your
warranty.
Your DPF equipped vehicle has specific fuel and engine
oil requirements. SeeWhat Fuel to Use on page 5-9
andEngine Oil (Caterpillar
®Diesel Engine) on
page 5-23orEngine Oil (Gasoline Engine) on page 5-24
orEngine Oil (DURAMAX
®Diesel Engine) on page 5-28
orEngine Oil (Isuzu Diesel Engine) on page 5-32to
make sure you use the required fuel and engine oil.
