2007 GMC ENVOY ECO mode

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 PARK (P).
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 RUN and LOCK twice. Then,
with the key in LOCK, 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.3. You are now ready to program the automatic
door locks. Select one of the two programming
options listed previously, and press the lock
side of the power door lock switch to
cycle through the lock options. You will have
30 seconds to begin programming. If you
exceed the 30-second limit, the locks
will automatically lock and unlock and the
horn will chirp twice to indicate that you have
left the program mode. If this occurs,
repeat the procedure beginning with Step 1 to
re-enter the programming mode.
You can exit the program mode any time by
turning the ignition to RUN. The locks will
automatically lock and unlock and the horn will
chirp twice to indicate that you are leaving
the program mode. If the lock/unlock switches are
not pressed while in the programming mode,
the current auto lock/unlock setting will not
be modied.
See your dealer for more information.

Programmable Unlocking Feature
The following is the list of available programming
options:
Mode 1:Driver’s door unlocks when the
transmission is shifted into PARK (P).
Mode 2:All doors unlock when the transmission
is shifted into PARK (P).
Mode 3:All doors unlock when the key is
removed from the ignition.
Mode 4:No automatic door unlock.
The automatic door locks were pre-programmed at
the factory to unlock all doors once the
transmission is shifted to PARK (P). The following
instructions detail how to program your door
locks differently than the factory setting. Choose
one of the four programming options listed
previously before entering the program mode.
To enter the program mode you need to 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 RUN and LOCK twice. Then,
with the key in LOCK, release the turn

{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and
some other things. Instead of trying to list
everything here, we ask that you contact your
dealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.
Active Fuel Management™
Your 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 your 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 your vehicle to
achieve better fuel economy. When greater
power demands are required, such as accelerating
from a stop, passing, or merging onto a freeway,
the system will maintain full-cylinder operation.

Four-Wheel Drive
If your vehicle has four-wheel drive, the engine’s
driving power can be sent to all four wheels
for extra traction. To get the most satisfaction out
of four-wheel drive, you must be familiar with
its operation. Read the part that follows before
using four-wheel drive. 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.
Automatic Transfer Case
If your 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.
Your front axle is not engaged in two-wheel drive.
It also provides the best fuel economy.
AUTO (Automatic Four-Wheel Drive):This
setting is ideal for use when road conditions are
variable. When driving your 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.

Compass Calibration
Press and hold the on/off button 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 following zone map.2. Press and hold the on/off button for
six seconds. Release the button when
(FOR ZONE) is displayed. The number shown
is the current zone number.
3. Scroll through the zone numbers that appear in
the 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.

Compass Variance
The mirror is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if you live
outside of zone eight. Under certain
circumstances, as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. Compass variance is the
difference between earth’s magnetic north and true
geographic north. 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 following zone map.
2. Press and hold the on/off button untilaZand
a zone number appear in the display. The
compass is now in zone mode.
3. Keep pressing the on/off button until the
