ECO mode CHEVROLET TRAIL BLAZER 2003 1.G Owners Manual

In many crashes severe enough to in¯ate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
·Air bags are designed to in¯ate only once. After an
air bag in¯ates, you'll need some new parts for
your air bag system. If you don't get them, the air
bag system won't be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
·Your vehicle is equipped with an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also equipped
with a crash sensing and diagnostic module,
which records information about the frontal air bag
system. The module records information about
the readiness of the system, when the system
commands air bag in¯ation and driver's safety belt
usage at deployment. The module also records
speed, engine rpm, brake and throttle data.
·Let only quali®ed technicians work on your air bag
systems. Improper service can mean that an air
bag system won't work properly. See your dealer for
service.
Notice:If you damage the covering for the driver's
or the right front passenger's air bag, or the air
bag covering on the driver's and right front
passenger's seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right front
passenger's air bag, or both the air bag module
and seatback for the driver's and right front
passenger's side impact air bag. Do not open or
break the air bag coverings.

Automatic Transfer Case
If your vehicle is equipped
with four-wheel drive, the
transfer case knob is
located to the right of the
steering wheel on the
instrument panel. Use this
knob to shift into and
out of four-wheel drive.
2HI (Two-Wheel High):This setting is for driving in
most street and highway situations. Your front axle is not
engaged in two-wheel drive. It also provides the best
fuel economy.A4WD (Automatic Four-Wheel Drive):This setting is
ideal for use when road conditions are variable.
When driving your vehicle in A4WD, the front axle is
engaged, but the vehicle's power is sent to the
rear wheels. When the vehicle senses a loss of traction,
the system will automatically engage four-wheel
drive. Driving in this mode results in slightly lower fuel
economy than 2HI.
4HI (Four-Wheel High):Use 4HI when you need extra
traction, such as on snowy or icy roads or in most
off-road situations. This setting also engages your front
axle to help drive your vehicle.
4LO (Four-Wheel Low):This setting also engages
your front axle and delivers extra torque. It sends
maximum power to all four wheels. You might choose
4LO if you are driving off-road in deep sand, deep mud,
and climbing or descending steep hills.

Compass Calibration
Press and hold the on/off button down for nine seconds
to activate the compass calibration mode. CAL will
be displayed in the compass window on the mirror.
The compass can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display
reads a direction.
Compass Variance
Compass variance is the difference between earth's
magnetic north and true geographic north. The mirror is
set to zone eight upon leaving the factory. It will be
necessary to adjust the compass to compensate
for compass variance if you live outside zone eight.
Under certain circumstances, such as during a
long distance cross-country trip, it will be necessary to
adjust for compass variance. If not adjusted to
account for compass variance, your compass could give
false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance zone
number on the map.2. Press and hold the on/off button for six seconds.
Release the button when ZONE is displayed. The
number shown is the current zone number.
3. Scroll through the zone numbers that appear in the
compass/temperature window on the mirror by
pressing the on/off button. Once you ®nd your
zone number, release the button. After about
four seconds, the mirror will return to the compass
display, and the new zone number will be set.

Programming the HomeLinkž
Transmitter
Do not use the HomeLinkžTransmitter with any garage
door opener that does not have the ªstop and reverseº
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow steps 6 through 8 to complete the
programming of your HomeLink
žTransmitter.Read the instructions completely before attempting to
program the HomeLink
žTransmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
žprogramming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
žbuttons should be erased
for security purposes. Refer to ªErasing HomeLinkž
Buttonsº or, for assistance, contact HomeLinkžon the
internet at: www.homelink.com or by calling
1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
¯ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
žbuttons.

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to ªtime outº or quit after several seconds of
transmission. This may not be long enough for
HomeLink
žto pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
ªtime outº in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
ªProgramming HomeLink
žº procedures (regardless of
where you live), replace Step 3 under ªProgramming
HomeLink
žº with the following:
Continue to press and hold the HomeLink
žbutton while
you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal has
been successfully accepted by HomeLink
ž. The
indicator light will ¯ash slowly at ®rst and then rapidly.
Proceed with Step 4 under ªProgramming HomeLink
žº
to complete.
Using HomeLinkž
Press and hold the appropriate HomeLinkžbutton for at
least half of a second. The indicator light will come
on while the signal is being transmitted.
Erasing HomeLinkžButtons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
the indicator light begins to ¯ash, after 20 seconds.
2. Release both buttons. Do not hold for longer than
30 seconds.
HomeLink
žis now in the train (learning) mode and can
be programmed at any time beginning with Step 2
under ªProgramming HomeLink
ž.º
Individual buttons can not be erased, but they can be
reprogrammed. See ªReprogramming a Single
HomeLink
žButtonº next.
Reprogramming a Single HomeLinkž
Button
To program a device to HomeLinkžusing a HomeLinkž
button previously trained, follow these steps:
1. Press and hold the desired HomeLink
žbutton.
Do not release the button.
2. The indicator light will begin to ¯ash after
20 seconds. While still holding the HomeLink
ž
button, proceed with Step 2 under ªProgramming
HomeLinkž.º

Operation Tips
·
Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
·When you enter a vehicle in cold weather, turn the
fan knob all the way to the right for a few moments
before driving. This helps clear the intake ducts
of snow and moisture, and reduces the chance of
fogging the inside of your window.
·Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
·Adding outside equipment to the front of your
vehicle, such as hood-air de¯ectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of your vehicle.
Dual Automatic Climate Control
System
Your vehicle may have the optional dual automatic
climate control system. With this system you can control
the heating, cooling and ventilation for your vehicle.
When your vehicle is ®rst started and the climate control
system is on, or if the climate control system has
been turned on, the display will show the driver's
temperature setting for ®ve seconds. Then it will show
the outside temperature.
OFF:Press this button to turn off the entire climate
control system. Outside air will still enter the vehicle, and
will be directed to the ¯oor. Press the AUTO button,
the mode button, the fan arrows, or either temperature
knob to turn the system on.

MODE:Press this button to manually select the air
delivery mode to the ¯oor, instrument panel, or
windshield outlets. The system will stay in the selected
mode until the mode button is pressed again or the
AUTO button is pressed.
Driver's Side Temperature Knob:Turn this knob
clockwise or counterclockwise to manually raise or lower
the temperature on the driver's side of the vehicle.
The display will show the temperature setting decreasing
or increasing and the word DRIVER will appear on
the display. This knob can also adjust the passenger's
side temperature setting simultaneously if the
two zones are linked. The words DRIVER and PASS
will then appear on the display.Passenger's Side Temperature Knob:Turn this knob
clockwise or counterclockwise to manually raise or
lower the temperature on the passenger's side of the
vehicle. The display will show the temperature
setting decreasing or increasing and the word PASS will
appear on the display. The passenger's temperature
setting can be set to match and link to the driver's
temperature setting by pressing and holding the AUTO
button for three seconds. Now, by adjusting the
driver's side temperature setting, the passenger's side
temperature setting will follow and both DRIVER
and PASS will appear on the display. The passenger's
side temperature setting also resets and relinks to
the driver's side temperature setting if the vehicle has
been off for more than two hours.
