2009 HUMMER H3 automatic transmission

Shifting Into Park
(Automatic Transmission)
{CAUTION
It can be dangerous to get out of
the vehicle if the shift lever is not
fully in P (Park) with the parking
brake rmly set. The vehicle can
roll. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, use the steps
that follow. If you are pulling a
trailer, seeTowing a Trailer on
page 4-42.
1. Hold the brake pedal down,
then set the parking brake.
SeeParking Brake on page 2-28
for more information.
{CAUTION
With all-wheel drive, the vehicle
will be free to roll — even if the
shift lever is in P (Park) — if the
transfer case is in Neutral. So, be
sure the transfer case is in a drive
gear, four-wheel high (4H) or
four-wheel low (4L) — not in
Neutral.
2. Move the shift lever into P (Park)
by pressing the shift lever button
and moving the lever as far
forward as it will go.
3. Turn the ignition key to
LOCK/OFF.
4. Remove the key from the
ignition.
Leaving Your Vehicle
With the Engine Running
(Automatic Transmission)
{CAUTION
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
rmly set. And, if you leave the
vehicle with the engine running,
it could overheat and even catch
re. You or others could be
injured. Do not leave the vehicle
with the engine running.
If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the parking
brake is rmly set before you
leave it. After you have moved the
shift lever into P (Park), hold
the regular brake pedal down.
Features and Controls 2-29

Then, see if you can move the shift
lever away from P (Park) without
rst pressing the shift lever button.
If you can, it means that the
shift lever was not fully locked into
P (Park).
Torque lock is when the weight of
the vehicle puts too much force
on the parking pawl in the
transmission. This happens when
parking on a hill and shifting
the transmission into P (Park) is
not done properly and then it
is difficult to shift out of P (Park).
To prevent torque lock, set the
parking brake and then shift into
P (Park). To nd out how, see
“Shifting Into P (Park)” listed
previously.
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so
you can shift out of P (Park).Shifting Out of Park
(Automatic
Transmission)
This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal
unless the shift lever is in P (Park)
with the shift lever button fully
released, and
Prevent movement of the shift
lever out of P (Park) unless
the ignition is in ON/RUN or
ACC/ACCESSORY and the
regular brake pedal is applied.
The shift lock release is always
functional except in the case of
a an uncharged or low voltage
(less than 9 volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. SeeJump Starting on
page 5-34for more information.To shift out of P (Park):
1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the
desired position.
If you still are unable to shift out
of P (Park):
1. Fully release the shift lever
button.
2. While holding down the brake
pedal, press the shift lever
button again.
3. Move the shift lever to the
desired position.
If you still cannot move the shift
lever from P (Park), consult your
dealer/retailer or a professional
towing service.

It is better not to park with the
engine running. But if you ever have
to, here are some things to know.
{CAUTION
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains Carbon Monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation.
For more information, seeEngine
Exhaust on page 2-31.
{CAUTION
It can be dangerous to get out
of the vehicle if the automatic
transmission shift lever is not fully
in P (Park) with the parking brake
rmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running unless you have
to. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when it is on
fairly level ground, always set
the parking brake and move the
automatic transmission shift lever
to P (Park), or the manual
transmission shift lever to Neutral.Follow the proper steps to be
sure the vehicle will not move.

Headlamps on Reminder
A headlamp reminder chime will
sound if the following conditions
are met:
The driver door is open.
Parking lamps or headlamps are
manually turned on.
The key is either not in the
ignition switch, or it is in the
LOCK/OFF position of the ignition
switch.
The headlamp reminder cannot be
turned off if the conditions listed
above are met.
In the automatic mode, the
headlamps turn off once the ignition
is in ACC/ACCESSORY.
Daytime Running
Lamps (DRL)
Daytime Running Lamps (DRL) can
make it easier for others to see
the front of your vehicle during the
day. Fully functional daytime
running lamps are required on all
vehicles rst sold in Canada.
The DRL system will come on when
the following conditions are met:
The ignition is on.
The exterior lamps control is
in AUTO.
The transmission is not in
P (Park), if the vehicle has
an automatic transmission.
The light sensor determines it is
daytime.When the DRL are on, no other
lamps are on. The instrument panel
will not be lit up either. For
vehicles rst sold in Canada, if
parking lamps are manually turned
on, DRL will stay on.
When it begins to get dark, the
automatic headlamp system will
switch from DRL to the headlamps.
The regular headlamp system
should be turned on when needed.
To turn off the DRL, seeExterior
Lamps on page 3-11.
Vehicles rst sold in Canada cannot
turn off DRL unless certain

Lamps on page 3-11.
Instrument Panel 3-13

Automatic Headlamp
System
When it is dark enough outside,
the automatic headlamp system
will turn on after the transmission
has been shifted from P (Park) to
D (Drive). The headlamps, taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrument
panel lights turn on at normal
brightness. The radio lights will
become dimmer when the
headlights are off compared to
when the headlights are on.
The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover the sensor,
or the system will be on whenever
the ignition is on.
The system can turn on the
headlamps when driving in a parking
garage, through a tunnel or when
there is overcast weather. This
is normal.There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp system so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system will only be
affected when the light sensor
detects a change in lighting lasting
longer than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system will come on immediately.
Once the vehicle leaves the garage,
it will take about one minute for
the automatic headlamp system to
change to DRL if it is light
outside. During that delay, the
instrument panel cluster may not be
as bright as usual. Make sure the
instrument panel brightness
control is in the full bright position.
SeeInstrument Panel Brightness on
page 3-15.
Off-Road Lamps
The off-road lamps, if the vehicle
has them, provide auxiliary lighting
when the vehicle is used off
road. These lamps are not intended
to be used in place of existing
vehicle lighting. The lamps are not
to be used on any public street
or highway and are to be covered
when not in use. Check your
state and local laws before installing
or using any auxiliary lighting. In
some states it may be necessary to
remove the roof lamps when
operating the vehicle on the
highway.
