ECO mode CHEVROLET TRAIL BLAZER 2009 1.G Owners Manual

Roof-rail airbags are not intended to inate in frontal
impacts, near-frontal impacts, or rear impacts. Both
roof-rail airbags will deploy when either side of the vehicle
is struck or if the sensing system predicts that the vehicle
is about to roll over.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, ination is determined by what
the vehicle hits, the angle of the impact, and how quickly
the vehicle slows down. For roof-rail airbags, deployment
is determined by the location and severity of the side
impact. In a rollover event, roof-rail airbag deployment
is determined by the direction of the roll.
What Makes an Airbag Inate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from the
inator. Gas from the inator lls the airbag causing the
bag to break out of the cover and deploy. The inator, the
airbag, and related hardware are all part of the airbag
module.
Frontal airbag modules are located inside the steering
wheel and instrument panel. For vehicles with roof-rail
airbags, there are airbag modules in the ceiling of the
vehicle, near the side windows that have occupant
seating positions.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the impact
more evenly over the occupant’s upper body, stopping
the occupant more gradually. Roof-rail airbags distribute
the force of the impact more evenly over the occupant’s
upper body.
Rollover capable roof-rail airbags are designed to help
contain the head and chest of occupants in the outboard
seating positions in the rst and second rows. The
rollover capable roof-rail airbags are designed to help
reduce the risk of full or partial ejection in rollover events,
although no system can prevent all such ejections.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not toward
those airbags. SeeWhen Should an Airbag Inflate? on
page 1-60for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.

Programmable Automatic Door
Locks
Your vehicle is equipped with an automatic lock/unlock
feature which enables you to program your vehicle’s
power door locks. You can program this feature through
the Driver Information Center (DIC), or by the following
method. SeeDIC Vehicle Customization on page 3-56.
Programmable Locking Feature
Following are the two locking modes that can be
programmed:
Mode 1:All doors lock when the transmission is shifted
out of (P) Park.
Mode 2:All doors lock when the vehicle speed is
greater than 8 mph (13 km/h).
The automatic door locks were pre-programmed at the
factory to lock all the doors when the transmission
is shifted into gear. The following instructions detail how
to program your door locks differently than the factory
setting. Choose one of the two programming options
listed previously before entering the program mode.
To enter the program mode, do the following:
1. Begin with the ignition off. Then pull the turn
signal/multifunction lever toward you and hold
it there while you perform the next step.
2. Turn the key to ON/RUN and LOCK/OFF twice.
Then, with the key in LOCK/OFF, release the
turn signal/multifunction lever. Once you do this,
you will hear the lock switch lock and unlock,
the horn will chirp twice, and a 30-second program
timer will begin.

Active Fuel Management™
The vehicle’s V8 engine may have Active Fuel
Management™. This system allows the engine to
operate on either all or half of its cylinders, depending
on driving conditions.
When less power is required, such as cruising at a
constant vehicle speed, the system will operate in the
half cylinder mode, allowing the vehicle to achieve better
fuel economy. When greater power is required, such
as accelerating from a stop, passing, or merging onto a
freeway, the system will maintain full-cylinder operation.
Automatic Transmission Operation
There are several different
positions for the gear shift
lever.
P (Park):This position locks the rear wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily.
2-26

Four-Wheel Drive
If the vehicle has four-wheel drive, the engine’s driving
power can be sent to all four wheels for extra traction.
Read the following before using four-wheel drive,
to become familiar with its operation. You should use
Two-Wheel High for most normal driving conditions.
Notice:Driving on clean, dry pavement in
Four-Wheel-Drive High or Four-Wheel-Drive Low for
an extended period of time may cause premature
wear on your vehicle’s powertrain. Do not drive on
clean, dry pavement in Four-Wheel-Drive High or
Four-Wheel-Drive Low for extended periods of time.
Notice:If you continually drive your vehicle with
the transfer case in AUTO or Four-Wheel Drive, you
could shorten the life of the transfer case or the
Four-Wheel Drive system. The selector switch
should be left in Two-Wheel Drive High mode. Only
use AUTO and Four-Wheel Drive when you need
extra traction such as in wet or slippery road
conditions.
Automatic Transfer Case
If the vehicle has 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.
2
m(Two-Wheel High):This setting is for driving in
most street and highway situations. The front axle is not
engaged in two-wheel drive. This provides the best
fuel economy.
2-30

AUTO (Automatic Four-Wheel Drive):This setting is
ideal for use when road conditions are variable.
When driving the vehicle in automatic four-wheel drive,
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 Two-Wheel High.
4
m(Four-Wheel High):This setting should be used
when you need extra traction, such as on snowy or icy
roads or in most off-road situations. This setting also
engages the front axle to help drive the vehicle.
4
n(Four-Wheel Low):This setting also engages the
front axle and delivers extra torque. It sends maximum
power to all four wheels. You might choose this
setting if you are driving off-road in deep sand, deep
mud, and climbing or descending steep hills.
{CAUTION:
Shifting the transfer case to Neutral can cause
the vehicle to roll even if the transmission is in
P (Park). You or someone else could be seriously
injured. Be sure to set the parking brake before
placing the transfer case in Neutral. SeeParking
Brake on page 2-34.
Neutral:Shift the vehicle’s transfer case to Neutral only
when towing the vehicle. SeeRecreational Vehicle
Towing on page 4-40for more information.
An indicator light in the knob will show you which
position the transfer case is in. The indicator lights will
come on briey when you turn on the ignition and
one will stay on. If the lights do not come on, you should
take the vehicle to your dealer/retailer for service. An
indicator light will ash while shifting the transfer case.
It will stay on when the shift is complete. If the
transfer case cannot make a requested shift, it will
return to the last chosen setting.

Universal Home Remote System
Operation (With One Triangular LED)
If there is one triangular Light Emitting Diode (LED)
indicator light above the Universal Home Remote
buttons, follow the instructions below.
This system provides a way to replace up to three
remote control transmitters used to activate devices
such as garage door openers, security systems,
and home automation devices.
Do not use the Universal Home Remote with any
garage door opener that does not have the stop and
reverse feature. This includes any garage door opener
model manufactured before April 1, 1982.Read the instructions completely before attempting to
program the Universal Home Remote. Because of
the steps involved, it may be helpful to have another
person available to assist you in the programming
the Universal Home Remote.
Keep the original hand-held transmitter for use in other
vehicles as well as for future Universal Home Remote
programming. It is also recommended that upon the sale
of the vehicle, the programmed Universal Home
Remote buttons should be erased for security purposes.
See “Erasing Universal Home Remote Buttons” later
in this section.
When programming a garage door, park outside of the
garage. Park directly in line with and facing the garage
door opener motor-head or gate motor-head. Be sure that
people and objects are clear of the garage door or gate
that is being programmed.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.
