2008 CHEVROLET KODIAK cruise control

Diesel Engine Exhaust Brake
If your vehicle has a Isuzu 6H Diesel Engine, it may
have an exhaust brake, which is located in the exhaust
system.
If your vehicle has a 6.6L DURAMAX
®6600 or
Caterpillar®Diesel Engine, it may have an exhaust
brake, which is controlled through the turbocharger.
The exhaust brake for both engines operates the same.
The exhaust brake switch
is located in the instrument
panel switchbank.
Push the bottom of the switch to turn the exhaust brake
on. When you push the top of the switch, the exhaust
brake will turn off.
There is an indicator light on the instrument panel
similar to the symbol on the switch, that comes on when
the exhaust brake is active. SeeExhaust Brake
Indicator Light on page 3-40for more information.While using the exhaust brake, the proper gear range
selection is important. The exhaust brake is most
effective if the gear range selected is the lowest possible
range that does not allow the engine rpm to go more
than 200 rpm above rated (full load) rpm. If you have a
Caterpillar
®Diesel Engine, do not exceed 2900 rpm.
If you have an Isuzu 6H Diesel engine, do not exceed
2550 rpm. If your vehicle has a DURAMAX
®6600
Diesel Engine, do not exceed 3600 rpm.
If your vehicle has an Allison
®1000/2200/2300/
2350/2500/2550 series automatic transmission and this
button is pressed, the transmission downshifts to a
factory default setting of third gear. To change
the default setting, or for more information on factory
default settings, contact your dealer/retailer for
assistance.
The accelerator and clutch pedals must be released in
order for the exhaust brake to engage. The exhaust
brake will automatically shut off when the antilock brake
system is active.
If your vehicle has a Caterpillar
®Diesel Engine or a
DURAMAX®6600 Diesel Engine, the exhaust brake will
become active in cruise control when you exceed the
set speed by 3 to 5 mph.

Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can raise it to the highest level
to give your legs more room when you exit and enter
the vehicle.
The lever that allows you to tilt the steering wheel is
located on the left side of the steering column.
To tilt the wheel, hold the wheel and pull the lever.
Then move the wheel to a comfortable position
and release the lever to lock the wheel in place.
Turn Signal/Multifunction Lever
The lever located on the left side of the steering column
includes the following:
•Turn and Lane-Change Signals. SeeTurn and
Lane-Change Signals on page 3-8.
•Headlamp High/Low-Beam Changer. SeeHeadlamp
High/Low-Beam Changer on page 3-8.
•Windshield Wipers. SeeWindshield Wipers on
page 3-9.
•Windshield Washer. SeeWindshield Washer on
page 3-10.
•Cruise Control (Option). SeeCruise Control on
page 3-10.

Windshield Washer
L(Washer Fluid):There is a paddle marked with the
windshield washer symbol at the top of the multifunction
lever. To spray washer fluid on the windshield, press
the paddle. The wipers will clear the window and
then either stop or return to your preset speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
Cruise Control
If your vehicle has
this feature, it is located at
the end of the multifunction
lever.
T(Set):Pressing in this button at the end of the
lever sets the cruise control speed.
9(Off):Moving the switch to this position turns off
the cruise control.
R(On):Moving the switch to this position turns on the
cruise control.
S(Resume/Accelerate):Moving the switch to this
position turns on resume/accelerate.
3-10

With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h).
If you have an automatic transmission and you apply
your brakes, the cruise control will shut off.
If you have a manual transmission and you apply your
brakes or push the clutch pedal, the cruise control
will shut off.
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press in the set button at the end of the lever
and release it.
4. Take your foot off the accelerator pedal.
The accelerator pedal will not go down.
3-11

Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts
off the cruise control. But you don’t need to reset it.
Once you’re going about 25 mph (40 km/h) or more,
you can move the cruise control switch briefly from on
to resume/accelerate.
The vehicle will return to your chosen speed and
stay there.
If you hold the switch at resume/accelerate, the vehicle
will keep going faster until you release the switch or
apply the brake. So unless you want to go faster, don’t
hold the switch at resume/accelerate.
Increasing Speed While Using
Cruise Control
There are two ways to go to a higher speed:
•Use the accelerator pedal to get to the higher
speed. Press the button at the end of the lever,
then release the button and the accelerator pedal.
You’ll now cruise at the higher speed.
•Move the cruise switch from on to resume/
accelerate. Hold it there until you get up to the
speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch briefly to resume/accelerate.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
Press in the button at the end of the lever until you
reach the lower speed you want, then release it.
To slow down in very small amounts, tap the button
briefly. Each time you do this, you’ll go 1 mph (1.6 km/h)
slower.
3-12

Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to
step on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake or clutch takes you out of cruise
control. Many drivers find this to be too much trouble
and don’t use cruise control on steep hills.
If your vehicle is equipped with the exhaust brake option
and the exhaust brake is turned on, the exhaust brake
may come on and try to slow down the vehicle to the set
cruise control speed if the vehicle has accelerated
past the set cruise control speed while going downhill.
Ending Cruise Control
There are four different ways to turn off the cruise
control:
•Step lightly on the brake pedal
(manual and automatic transmissions).
•Press the clutch pedal to the floor
(manual transmissions).
•Move the cruise switch to off, or
•Shift the transmission to NEUTRAL (N).
Erasing Speed Memory
When you turn off the ignition, your cruise control set
speed memory is erased.
