2003 Oldsmobile Bravada transmission

Torque Lock
If you are parking on a hill and you don’t shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may find it difficult to pull the
shift lever out of PARK (P). This is called “torque
lock.” To prevent torque lock, set the parking brake and
then shift into PARK
(P) properly before you leave
the driver’s seat. To find out how, see
Shifting Into Park
(P) on page 2-25.
When you are ready to drive, move the shift lever out of
PARK (P)
before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission,
so
you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply the regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. See
Automatic Transmission
Operation
on page 2-22.
If you cannot shift out of PARK (P), ease pressure on
the shift lever. Push the shift lever all the way into
PARK (P) as you maintain brake application. Then press
the shift lever button and move the shift lever into the
gear you want.
If you ever hold the brake pedal down but still can’t shift
out of PARK (P), try this:
1. Turn the key to LOCK.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as possible.

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
flash, 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@
buttons.
2. Position the end of your hand-held transmitter
about
1 to 3 inches (3 to 8 cm) away from the
HomeLink@ buttons while keeping the indicator light
in view.
button on HomeLink@ and the hand-held
transmitter button.
Do not release the buttons until
Step
4 has been completed.
Some entry gates and garage door openers may
require you to substitute Step
3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
4. The indicator light will flash slowly at first and then
rapidly after HomeLink@ successfully receives the
frequency signal from the hand-held transmitter. Release both buttons.
3. Simultaneously press and hold both the desired
5. Press and hold the newly-trained HomeLink@
button and observe the indicator light.
If the indicator light stays on constantly,
programming is complete and your device should
activate when the HomeLink@ button is pressed and
released.
To program the remaining two HomeLink@ buttons,
begin with Step
2 under “Programming
HomeLink@
.” Do not repeat Step 1 as this will
erase all of the programmed channels.
If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps
6 through 8 following to complete the
programming of a rolling-code equipped device
(most commonly, a garage door opener).
6. At the garage door opener receiver (motor-head
unit) in the garage, locate the “Learn’’ or “Smart”
button. This can usually be found where the hanging
antenna wire is attached to the motor-head unit.
7. Firmly press and release the “Learn” or “Smart”
button. The name and color of the button may
vary by manufacturer.
You will have

8. Return to the vehicle. Firmly press and hold the
programmed HomeLink@ button for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener (or other rolling
code device), repeat this sequence a third time
to complete the programming.
HomeLink@ should now activate your rolling code
equipped device.
To program the remaining two HomeLink@ buttons,
begin with Step
2 of “Programming HomeLink@ .” Do not
repeat Step
1.
Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals
to “time out” or quit after several seconds of
transmission. This may not be long enough for
HomeLink@ to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured
to
“time out” in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
“Programming HomeLink@
” procedures (regardless of
where you live), replace Step
3 under “Programming
HomeLink@
” with the following: Continue
to press and hold the HomeLink@ button while
you press and release every two seconds (cycle) your
hand-held transmitter until the frequency signal has been
successfully accepted by HomeLink@
. The indicator
light will flash slowly at first and then rapidly. Proceed
with Step
4 under “Programming HomeLink@” to
complete.
Using HomeLink@
Press and hold the appropriate HomeLink@ button for
at least half of a second. The indicator light will come on
while the signal
is being transmitted.
Erasing HomeLink@ Buttons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
2. Release both buttons. Do not hold for longer than
HomeLink@ is now in the train (learning) mode and can
be programmed at any time beginning with Step
2
under “Programming HomeLink@ .”
Individual buttons can not be erased, but they can be
reprogrammed. See “Reprogramming a Single
HomeLink@ Button” next. the
indicator light begins to flash, after

Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
0
e
Use the accelerator pedal to get to the higher
speed. Press the button at the end of the lever, then
release the button and the accelerator pedal.
You’ll now cruise at the higher speed.
Move the cruise switch from on
to
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch briefly
to resume/accelerate. Each
time you do this, your vehicle will go about
1 rnph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
Press in the set button at the end of the lever until
you reach the lower speed you want, then release it.
0 To slow down in very small amounts, briefly press
the set button. Each time you do this, you’ll
go about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control 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 want
to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have
to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers find this
to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are three ways to turn off the cruise control:
Step lightly on the brake pedal.
Move the cruise switch to off, or
Shift the transmission to NEUTRAL (N).
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Use the accelerator pedal
to increase your speed.
When you take your foot
off the pedal, your vehicle will
slow down
to the cruise control speed you set earlier.

Daytime Running Lamps
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
first sold in Canada.
The DRL system will make your headlamps come on
at
reduced brightness when the following conditions
are met:
The ignition is on,
the exterior lamps knob is in automatic
the light sensor detects daytime light, and
the transmission is not in PARK (P).
headlamp
mode,
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either.
When it begins
to get dark, the headlamps will
automatically switch from DRL
to the regular headlamps.
Fog Lamps
Your vehicle may have this feature. Use your fog lamps
for better vision in foggy or misty conditions. Your
ignition must be in RUN for your fog lamps
to work.
The fog lamp button is
located on the instrument
panel
to the right of
the exterior lamps knob.
Press the button
to turn thl
fog lamps on. Press the e
button again to turn them off. A light will glow near the
button when the fog lamps are on. Fog lamps will
turn off whenever your high-beam headlamps are on.

This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON or CHECK
ENGINE light comes on and a chime will sound
to
indicate that there is a problem and service is required. Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage
to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Notice: If you keep driving your vehicle with this
light on, after a while, your emission controls
may not work as well, your fuel economy may not
be as good and your engine may not run as
smoothly. This could lead to costly repairs that may not be covered by your warranty.
Notice: Modifications made to the engine,
transmission, exhaust, intake or fuel system of your
vehicle or the replacement of the original tires
with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modifications to these systems could lead to costly
repairs
not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.

This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light doesn’t come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
0 Light Flashing - A misfire condition has been
detected. A misfire increases vehicle emissions
and may damage the emission control system on
your vehicle. Dealer or qualified service center
diagnosis and service may be required.
Light On Steady - An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis
and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady’’ following.

Traction Assist System (TAS)
Your vehicle has a Traction Assist System (TAS) that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only
if it senses
that one or both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the system reduces engine power to limit wheel spin.
The LOW TRAC light next
to the button will come
on when the TAS is limiting wheel spin. You may feel or
hear the system working, but this is normal.
The Traction Assist System may operate on dry roads
under some conditions. When this happens, you
may notice a reduction in acceleration. This is normal
and doesn’t mean there’s a problem with your vehicle.
Examples of these conditions include a hard
acceleration in a turn, an abrupt upshift or downshift
of
the transmission or driving on rough roads.
If your vehicle is in cruise control when the TAS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may re-engage the cruise control. See
Cruise Control Light on page 3-40. When the TRAC
OFF light on the button is on, the TAS is off and will not
limit wheel spin. Adjust your driving accordingly. The TRAC
OFF light
on the button will come on under
the following conditions:
0 The Traction Assist System is turned off, either by
pressing the TAS on/off button or by turning
off
the automatic engagement feature of the TAS.
The transmission is in FIRST (1) gear; TAS will not
operate in this gear. This is normal.
0 The vehicle is driven on an extremely rough road.
When the vehicle leaves the rough surface,
slows
down or stops, the light will go off and TAS will
be on again. This is normal.
A Traction Assist System, Anti-Lock Brake System
or engine-related problem has been detected and
the vehicle needs service.
The Traction Assist System, as delivered from the factory, will automatically come on whenever you start
your vehicle. To limit wheel spin, especially in
slippery road conditions, you should always leave the
system on. But you can turn the TAS
off if you ever need
to. You shouid turn the TAS
off if your vehicle ever
gets stuck in sand, mud or snow and rocking the vehicle
is required.
