2008 CHEVROLET AVALANCHE Owners Manual

Setting Cruise Control
Cruise control will not work if your parking brake is set,
or if the master cylinder brake uid level is low.
The cruise control light on the instrument panel cluster
will come on after the cruise control has been set to
the desired speed.
{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. Press the cruise control On/Off button.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This shuts off the
cruise control. But you do not need to reset it.
Once you are driving about 25 mph (40 km/h) or
more, press the +RES button on your steering wheel.
The vehicle will go back to the previous set speed and
stay there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until you reach your new desired speed,
then release it.
To increase vehicle speed in small increments,
press the +RES button. Each time you do this,
you will go about 1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the steering
wheel until the desired lower speed is reached,
then release it.
To slow down in very small amounts, press the
SET– button on the steering wheel briey. Each
time you do this, the vehicle will go about 1 mph
(1.6 km/h) slower.
3-13

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 previous set cruise speed.
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 have to step
on the accelerator pedal to maintain the vehicle’s speed.
When going downhill, you may have to brake or shift
to a lower gear to keep the vehicle’s speed down.
Of course, applying the brake takes you out of cruise
control. Many drivers nd this to be too much trouble
and do not use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the cancel button on the steering wheel.
Press the On/Off button on the steering wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Exterior Lamps
The exterior lamps
control is located on the
instrument panel to the left
of the steering wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
The exterior lamps control has four positions:
9(Off):Turn the control to this position to turn off the
automatic headlamps and daytime running lamps (DRL).
Turn the headlamp control to the off position again to turn
the automatic headlamps or DRL back on.
For vehicles rst sold in Canada, the off position will only
work when the vehicle is shifted into PARK (P).
3-14

AUTO (Automatic):Turn the control to this position
to automatically turn on the headlamps at normal
brightness, together with the following:
Parking Lamps
Instrument Panel Lights
Taillamps
License Plate Lamps
When the vehicle is turned off and the headlamps are
in AUTO, the headlamps may automatically remain
on for a set time. The time of the delay can be changed
using the DIC. SeeDriver Information Center (DIC)
on page 3-50.
;(Parking Lamps):Turn the control to this position
to turn on the parking lamps together with the following:
Instrument Panel Lights
Taillamps
License Plate Lamps
2(Headlamps):Turn the control to this position to
turn on the headlamps together with the following:
Parking Lamps
Instrument Panel Lights
Taillamps
License Plate LampsWhen the headlamps are turned on while the vehicle is
on, the headlamps turn off automatically 10 minutes after
the ignition is turned off. When the headlamps are turned
on while the vehicle is off, the headlamps will stay on for
10 minutes before automatically turning off to prevent the
battery from being drained. Turn the headlamp control to
off and then back to the headlamp on position to make
the headlamps stay on for an additional 10 minutes.
Push the turn signal/multifunction lever toward the
instrument panel to change the headlamps from low
beam to high beam.
Headlamps on Reminder
If a door is open, a reminder chime will sound when
your headlamps or parking lamps are manually turned on
and your key is out of the ignition. To turn off the chime,
turn the headlamp switch to off or AUTO and then back
on, or close and re-open the door. In the AUTO mode, the
headlamps turn off once the ignition is in LOCK or may
remain on until the headlamp delay ends (if enabled in
the DIC). See “Exit Lighting” underDIC Vehicle
Customization (With DIC Buttons) on page 3-66.
3-15

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P).
The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release. For
vehicles rst sold in Canada, the transmission must be
in the PARK (P) position, before the DRL lamps can
be turned off.
Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, the automatic headlamp system will
turn on the headlamps at the normal brightness along
with other lamps such as the taillamps, sidemarker,
parking lamps, roof marker lamps, and the instrument
panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then release.
For vehicles rst sold in Canada, the transmission must
be in the PARK (P) position, before the automatic
headlamp system can be turned off.
The vehicle has a light sensor located on the top of
the instrument panel. Be sure it is not covered, or
the system will be on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems
so that driving under bridges or bright overhead street
lights does not affect the system. The DRL and automatic
headlamp system will only be affected when the light
sensor sees a change in lighting lasting longer than
the delay.
3-16

If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once the
vehicle leaves the garage, it takes approximately one
minute for the automatic headlamp system to change to
DRL if it is light outside. During that delay, the instrument
panel cluster may not be as bright as usual. Make sure
the instrument panel brightness control is in the full bright
position. SeeInstrument Panel Brightness on page 3-18.
Fog Lamps
If your vehicle has fog lamps you can use them for
better vision in foggy or misty conditions. Your parking
lamps and/or low-beam headlamps must be on for
your fog lamps to work.
The fog lamp button is located on the left side of your
instrument panel.
-(Fog Lamps):Press the button to turn the fog
lamps on. An indicator light will glow near the button
when the fog lamps are on. Press the button again
to turn them off.Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps
in the dark without turning on the headlamps.
The fog lamps will go off whenever your high-beam
headlamps come on. When the high beams go off,
the fog lamps will come on again.
The fog lamps will be cancelled after the ignition is
turned off. If you still want to use the fog lamps after
you restart the vehicle, you will need to press the
fog lamp button again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Exterior Cargo Lamps
You can use the cargo lamp if you need more light in
the cargo area of your vehicle or in the top-box storage
units. Some vehicles will only have a cargo lamp in
the driver side top box.
The cargo lamps come on by turning on the interior
dome lamps.

Instrument Panel Brightness
The knob for this feature is located next to the exterior
lamps control.
D(Instrument Panel Lights):Turn the knob
clockwise or counterclockwise to brighten or dim the
instrument panel lights and the radio display. This only
works if the headlamps or parking lamps are on.
To turn on the dome lamps, with the vehicle doors
closed, turn the knob all the way clockwise.
Dome Lamps
The dome lamps come on when any door is opened.
They turn off after all the doors are closed.
The dome lamps can also be turned on by turning the
instrument panel brightness knob, located next to
the exterior lamps control, clockwise to the farthest
position. In this position, the dome lamps remain
on whether a door is opened or closed.
Dome Lamp Override
The dome lamp override button is located next to the
exterior lamps control.
k(Dome Off):Press the button in and the dome
lamps remain off when a door is opened. Press the button
again to return it to the extended position so that the
dome lamps come on when a door is opened.
Entry/Exit Lighting
Your vehicle has an illuminated entry/exit feature.
When a door is opened or the key is removed from
the ignition, the dome lamps will come on if the dome
override button is in the out position.
Reading Lamps
If your vehicle has reading lamps, press the button
located next to the lamp to turn it on or off.
Your vehicle may also have reading lamps in other
locations. To turn each one on or off, press the button
located next to the lamp. The lamps cannot be adjusted.
3-18

Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up
or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as Battery Saver Active or
Service Battery Charging System. If this message is
displayed, it is recommended that the driver reduce the
electrical loads as much as possible. SeeDIC Warnings
and Messages on page 3-59.
Battery Run-Down Protection
This feature shuts off the dome lamps if they are left on
for more than 10 minutes when the ignition is in LOCK.
This will help prevent the battery from running down.
3-19

Accessory Power Outlet(s)
Your vehicle may have two accessory power outlets
located on the instrument panel and one inside
the center oor console.
Your vehicle may also have an outlet on the rear of the
center oor console above the cupholder door.
To use an outlet, remove the protective cap. When not
in use, always cover the outlet with the protective cap.
The accessory power outlet is operational at all times.
Notice:Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would
not be covered by the vehicle warranty. Do not use
equipment exceeding maximum amperage rating
of 20 amperes. Check with your dealer/retailer before
adding electrical equipment.
Certain power accessory plugs may not be compatible
to the accessory power outlets and could result in
blown vehicle or adapter fuses. If you experience
a problem, see your dealer/retailer for additional
information on the accessory power plugs.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
Ashtray(s) and Cigarette Lighter
If your vehicle has this feature it is located in the center
console or on the instrument panel. Pull up on the
ashtray door to open it if it is in the console or pull
the door open it if it is on the instrument panel.
Notice:If papers, pins, or other ammable items
are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage your vehicle. Never put ammable items in
the ashtray.
To remove the ashtray, pull it out from the console
or from the slide out door. To reinstall the ashtray,
slide it back to the original position.
To use the cigarette lighter, if the vehicle has one, push
it in all the way, and let go. When it is ready for use,
it will pop back out by itself.
Do not use the lighter to plug in accessory devices.
Use the power outlets provided.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from
the heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold
a cigarette lighter in while it is heating.
