Automatic
Transmission
The vehicle has an electronic shift
position indicator within the
instrument panel cluster.
There are several different positions
for the shift lever.
See“Range Selection Mode” in this
section.
P (Park): This position locks the
rear wheels. It is the best position to
use when you start the engine
because the vehicle cannot move
easily. When parked on a hill, especially
when the vehicle has a heavy load,
you may notice an increase in the
effort to shift out of P (Park). See
Shifting Into Park on page 9‑4.
{WARNING
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly 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
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
See
Shifting Into Park on
page 9‑4. If you are pulling a
trailer, see “Driving
Characteristics and Towing Tips”
in the owner manual.
{WARNING
If you have Four-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, Two-Wheel Drive High
or Four-Wheel Drive High or
Four-Wheel Drive Low —not in
Neutral. See Shifting Into Park
on page 9‑4.

Shifting Out of Neutral
To shift the transfer case out of
N (Neutral):
1. Set the parking brake and apply the regular brake pedal.
2. Turn the ignition to ON/RUN with the engine off, and shift the
transmission to N (Neutral). 3. Turn the transfer case dial to the
desired transfer case shift
position (Two-Wheel Drive High,
Four-Wheel Drive High, AUTO).
After the transfer case has
shifted out of N (Neutral), the
N (Neutral) light will go out.
4. Release the parking brake prior to moving the vehicle.
Notice: Shifting the transmission
into gear before the Four-Wheel
Drive Low indicator light has
stopped flashing could damage

Notice:Using coolant other than
a pre‐mixed DEX-COOL, available
at your dealer, may damage your
vehicle. Any repairs would not be
covered by your warranty. Always
use a pre‐mixed DEX-COOL
(silicate-free) coolant in your
vehicle.
{WARNING
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.

Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses, circuit
breakers and fusible thermal links.
This greatly reduces the chance of
fires caused by electrical problems.
Be sure you replace a bad fuse with
a new one of the identical size and
rating.If you ever have a problem on the
road and do not have a spare fuse,
you can borrow one that has the
same amperage. Just pick some
feature of the vehicle that you can
get along without, like the radio or
cigarette lighter, and use its fuse,
if it is the correct amperage.
Replace it as soon as you can.
The vehicle also has a special fuse
in the battery box for the 300-volt
batteries. If this fuse has failed and
needs to be replaced, the vehicle
will be disabled and you will need to
have the vehicle repaired by your
dealer. Do not attempt to
self-service this fuse.

4. Start with the driver side front tire.
5. Remove the valve cap from the valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire's air pressure
for five seconds, or until a horn
chirp sounds. The horn chirp,
which may take up to
30 seconds to sound, confirms
that the sensor identification
code has been matched to this
tire and wheel position.
6. Proceed to the passenger side front tire, and repeat the
procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the
procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure in
Step 5. The horn sounds two
times to indicate the sensor identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.
11. Put the valve caps back on the valve stems.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 miles).
Any time you notice unusual
wear, rotate your tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels. See
“When It Is Time for New Tires” and
“Wheel Replacement” in the
owner manual for more
information.
The purpose of regular rotation
is to achieve more uniform wear
for all tires on the vehicle. The
first rotation is the most
important. See “Scheduled
Maintenance ”in the owner
manual.
When rotating your tires, always
use the correct rotation pattern
shown here.

If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers.
SeeIf a Tire Goes Flat on
page 10‑22 for other important
safety warnings.
Do not remove any objects that
have penetrated the tire.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑31.
Make sure the on/off button (D)
is in the off (O) position.
2. Unwrap the sealant/air hose (G) and the power plug (C).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it
counterclockwise. 5. Attach the sealant/air hose (G)
onto the tire valve stem. Turn it
clockwise until it is tight.
6. Plug the power plug (C) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See “Power Outlets” in the
owner manual.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.
7. Start the vehicle. The vehicle must be running while using the
air compressor.
8. Press the on/off (D) button to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire. The pressure gauge (E) will
initially show a high pressure
while the compressor pushes the
sealant into the tire. Once the
sealant is completely dispersed
into the tire, the pressure will
quickly drop and start to rise
again as the tire inflates with
air only.
9. Inflate the tire to the recommended inflation pressure
using the pressure gauge (E).
The recommended inflation
pressure can be found on the
Tire and Loading Information
label. See Tire Pressure on
page 10‑17.
The pressure gauge (E) may
read higher than the actual tire
pressure while the compressor is
on. Turn the compressor off to
get an accurate pressure
reading. The compressor may
be turned on/off until the correct
pressure is reached.

Black plate (27,1)Chevrolet Tahoe and GMC Yukon/Yukon Denali Hybrid - 2011
Vehicle Care 10-27
Notice:If the recommended
pressure cannot be reached after
approximately 25 minutes, the
vehicle should not be driven
farther. The tire is too severely
damaged and the tire sealant and
compressor kit cannot inflate the
tire. Remove the power plug from
the accessory power outlet and
unscrew the inflating hose from
the tire valve. See “Roadside
Assistance Program” in the
owner manual.
10. Press the on/off button (D) to
turn the tire sealant and
compressor kit off.
The tire is not sealed and will
continue to leak air until the
vehicle is driven and the
sealant is distributed in the tire,
therefore, Steps 11 through
17 must be done immediately
after Step 10.
Be careful while handling the
tire sealant and compressor kit
as it could be warm after
usage. 11. Unplug the power plug (C) from
the accessory power outlet in
the vehicle.
12. Turn the sealant/air hose (G) counterclockwise to remove it
from the tire valve stem.
13. Replace the tire valve stem cap.
14. Replace the sealant/air hose (G), and the power
plug (C) back in their original
location.
15. If the flat tire was able to inflateto the recommended inflation
pressure, remove the
maximum speed label from the
sealant canister (B) and place
it in a highly visible location. Do not exceed the speed on
this label until the damaged tire
is repaired or replaced.
16. Return the equipment to its original storage location in the
vehicle.
17. Immediately drive the vehicle 8 km (5 miles) to distribute the
sealant in the tire.
18. Stop at a safe location and check the tire pressure. Refer
to Steps 1 through 11 under
“Using the Tire Sealant and
Compressor Kit without Sealant
to Inflate a Tire (Not
Punctured).”
If the tire pressure has fallen
more than 68 kPa (10 psi)
below the recommended
inflation pressure, stop driving
the vehicle. The tire is too
severely damaged and the tire
sealant cannot seal the tire.
See“Roadside Assistance
Program” in the owner manual.
