142 Instruments and Controls
instructions refer to a garage door
opener, but can be used for other
devices.
Do not use the Universal Remote
system 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 these instructions completely
before programming the Universal
Remote system. It may help to have
another person assist with the
programming process.
Keep the original hand-held
transmitter for use in other vehicles
as well as for future programming.
Erase the programming when
vehicle ownership is terminated.
See“Erasing Universal Remote
System Buttons” later in this
section.
To program a garage door opener,
park outside directly in line with and
facing the garage door opener
receiver. Clear all people and
objects near the garage door. Make sure the hand-held transmitter
has a new battery for quicker and
more accurate transmission of the
radio-frequency signal.
Programming the Universal
Remote System
For questions or programming help,
see www.homelink.com/gm or call
1-800-355-3515. For calls placed
outside the U.S., Canada, or Puerto
Rico, international rates will apply
and may differ based on landline or
mobile phone.
Programming involves
time-sensitive actions, and may time
out causing the procedure to be
repeated.
To program up to three devices:
1. Hold the end of the hand-held transmitter about 3 to 8 cm (1
to 3 in) away from the
Universal Remote system
buttons with the indicator light
in view. The hand-held
transmitter was supplied by the
manufacturer of the garage
door opener receiver. 2. At the same time, press and
hold both the hand-held
transmitter button and one of
the three Universal Remote
system buttons to be used to
operate the garage door. Do
not release either button until
the indicator light changes from
a slow to a rapid flash. Then
release both buttons.
Some garage door openers
may require substitution of
Step 2 with the procedure
under “Radio Signals for Some
Gate Operators” later in this
section.
3. Press and hold the newly programmed Universal Remote
system button for five seconds
while watching the indicator
light and garage door
activation.
.If the indicator light stays on
continuously or the garage
door moves when the
button is pressed, then
programming is complete.
There is no need to
complete Steps 4–6.

Driving Information
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
. Set the climate controls to the
desired temperature after the
engine is started, or turn them
off when not required.
. On AWD vehicles, see Driver
Mode Control 0196.
. Avoid fast starts and accelerate
smoothly.
. Brake gradually and avoid
abrupt stops.
. Avoid idling the engine for long
periods of time.
. When road and weather
conditions are appropriate, use
cruise control.
. Always follow posted speed
limits or drive more slowly when
conditions require. .
Keep vehicle tires properly
inflated.
. Combine several trips into a
single trip.
. Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.
. Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms
and can take your focus from the
task of driving. Exercise good
judgment and do not let other
activities divert your attention away
from the road. Many local
governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, keep
your eyes on the road, keep your
hands on the steering wheel, and
focus your attention on driving.

pedal down.
Caution
If the vehicle does not shift gears,
the transmission could be
damaged. Have the vehicle
serviced right away.
If the vehicle is stopped on a hill,
with your foot off the brake pedal,
the vehicle may roll. This is normal
and is due to the torque converter designed to improve fuel economy
and performance. Use the brake to
hold the vehicle on a hill. Do not use
the accelerator pedal.
If equipped with the 2.0L L4 engine,
engine speeds may be increased
while driving at highway speeds
while the engine is still warming up.
L :
This position gives you access
to gear ranges. This provides more
engine braking but lower fuel
economy than D (Drive). You can
use it on very steep hills, or in deep
snow or mud. See Manual Mode
0 189.
Operating Modes : The
transmission may operate in a lower
gear than normal to improve vehicle
performance. The engine speed
may be higher and there may be an
increase in noise during the
following conditions:
. When climbing a grade
. When driving downhill
. When driving in hot
temperatures, or at high altitude

190 Driving and Operating
To use this feature:1. Press the shift lever button and move the shift lever to L (Low).
2. Press + (Plus) or −(Minus) on
the shift lever to increase or
decrease the gear range
available.
When you shift from D (Drive) to
L (Low), the transmission will shift to
a pre-determined lower gear range.
The highest gear available for this
pre-determined range is displayed
next to the L in the DIC. See Driver
Information Center (DIC) (Base and
Midlevel) 0129 or
Driver Information Center (DIC)
(Uplevel) 0133. The number
displayed in the DIC is the highest
gear that the transmission will be
allowed to operate in. This means
that all gears below that number are
available. For example, when
4 (Fourth) is shown next to the L,
1 (First) through 4 (Fourth) gears are
automatically shifted by the vehicle.
The transmission will not shift into
5 (Fifth) until the + (Plus) button is
used or you shift back into D (Drive). If the transmission is in 9 (ninth)
gear when L (low) is selected, a
downshift to 7 (seventh) will be
commanded. If in 8 (eighth) through
2 (second), a single downshift will
occur.
While in L (Low), the transmission
will prevent shifting to a lower gear
range if the engine speed is too
high. You have a brief period of time
to slow the vehicle. If vehicle speed
is not reduced within the time
allowed, the lower gear range shift
will not be completed. You must
further slow the vehicle, then press
−
(Minus) to the desired lower gear
range. Automatic Engine Grade Braking is
not available when the ERS is
active. It is available in D (Drive) for
