2006 GMC YUKON brake

Parking Brake
To set the parking brake, hold the regular brake pedal
down with your right foot. Push down the parking
brake pedal with your left foot.
A chime will activate and the warning light will ash
when the parking brake is applied and the vehicle
is moving at least 3 mph (5 km/h) for at least
three seconds.
To release the parking brake, hold the regular brake
pedal down. Pull the bottom edge of the lever, located
above the parking brake pedal, with the parking
brake symbol, to release the parking brake.If the ignition is on when the parking brake is released,
the brake system warning light will go off.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-60.

Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle
will not move, even when you are on fairly
level ground, use the steps that follow.
With four-wheel drive, if your transfer case
is in NEUTRAL, your vehicle will be free to
roll, even if your shift lever is in PARK (P).
So, be sure the transfer case is in a drive
gear — not in NEUTRAL. If you are pulling
a trailer, seeTowing a Trailer on page 4-60.1. Hold the brake pedal down with your right foot
and set the parking brake.
2. Move the shift lever into the PARK (P) position
by pulling the shift lever toward you and moving
it up as far as it will go.
3. Be sure the transfer case is in a drive
gear — not in NEUTRAL (N).
4. Turn the ignition key to LOCK.
5. Remove the key and take it with you. If you
can leave your vehicle with the ignition key in
your hand, your vehicle is in PARK (P).

Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle could
move suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
If you have four-wheel drive and your transfer
case is in NEUTRAL, your vehicle will be free
to roll, even if your shift lever is in PARK (P).
So be sure the transfer case is in a drive
gear — not in NEUTRAL.
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
your vehicle with the engine running unless
you have to.If you have to leave your vehicle with the engine running,
be sure your vehicle is in PARK (P) and the parking
brake is rmly set before you leave it. After you move
the shift lever into PARK (P), hold the regular brake pedal
down. Then, see if you can move the shift lever away
from PARK (P) without rst pulling it toward you. If you
can, it means that the shift lever was not fully locked
into PARK (P).
Torque Lock
If you are parking on a hill and you do not 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 nd 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 nd out how, seeShifting
Into Park (P) on page 2-32.
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).
2-33

Shifting Out of Park (P)
Automatic Transmission
Your vehicle has an automatic transmission shift lock
control system which locks the shift lever in PARK (P)
when the ignition is in the LOCK position. You have
to fully apply your regular brakes before you can shift
from PARK (P) when the ignition is in RUN. See
Automatic Transmission Operation on page 2-23.
If you cannot shift out of PARK (P), ease pressure on
the shift lever and push the shift lever all the way up
into PARK (P) as you maintain brake application.
Then, 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 ACCESSORY. There is no shift
interlock in this key position.
2. Apply and hold the brake until the end of Step 4.
3. Shift the transmission to NEUTRAL (N).
4. Start the vehicle and then shift to the gear
you want.
5. Have the system xed as soon as you can.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Do not
park over papers, leaves, dry grass, or other
things that can burn.
2-34

Running the Engine While Parked
It is better not to park with the engine running.
But if you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 2-35.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle
even if the climate control fan is at the
highest setting. One place this can happen
is a garage. Exhaust — with CO — can come
in easily. NEVER park in a garage with the
engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 4-40.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. Do not leave your 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 your vehicle will not move, even
when you are on fairly level ground, always
set your parking brake and move the shift
lever to PARK (P).
2-36

{CAUTION:
Four-wheel drive vehicles with the transfer
case in NEUTRAL will allow the vehicle to roll,
even if your shift lever is in PARK (P). So, be
sure the transfer case is in a drive gear — not
in NEUTRAL. Always set your parking brake.
Follow the proper steps to be sure your vehicle will
not move. SeeShifting Into Park (P) on page 2-32.
If you are pulling a trailer, seeTowing a Trailer
on page 4-60.

Vehicle Personalization
In addition to the following features, your vehicle may
also have features that can be programmed through
the Driver Information Center (DIC). SeeDIC Vehicle
Customization on page 3-67for more information.
Memory Seat
If your vehicle has this
feature, the controls for
the memory function
are located on the
driver’s door.
These buttons are used to program and recall memory
settings for the driver’s seat, both the driver’s and
passenger’s outside mirrors, and the throttle and brake
pedals for vehicles with the adjustable throttle and
brake pedal feature. The settings for these features
can be saved for up to two drivers.To store the memory settings, do the following:
1. While the vehicle is in PARK (P), adjust the driver’s
seat, including the seatback recliner, lumbar, and
side wing area if your vehicle has this feature, both
of the outside mirrors, and the throttle and brake
pedals to your preference.
2. Press and hold the 1 or 2 button of the memory
control for three seconds. A double chime will
sound to let you know that the position has
been stored.
To repeat the procedure for a second driver, follow
the preceding steps, but press the other numbered
memory control button.
Each time button 1 or 2 is pressed and released while
the vehicle is in PARK (P), a single chime will sound
and the memory position will be recalled.
To stop recall movement of the memory seat feature at
any time, press one of the memory buttons or power
seat controls.
