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.
If the DMCM coolant is empty, the
vehicle must be serviced by your
dealer and a special fill procedure
must be followed.
Notice: Attempting to fill the
DMCM cooling surge tank
yourself when the fluid level is
empty can damage your vehicle.
Your vehicle must be serviced.
1. Park the vehicle on a level surface and turn the vehicle off.
Remove the DMCM coolant
surge tank pressure cap when
the DMCM cooling system,
including the DMCM coolant
surge tank pressure cap and
DMCM cooling hoses, are no
longer hot. Turn the DMCM
coolant surge tank pressure cap
slowly counterclockwise (left)
about one full turn. Wait
30 seconds.2. Then keep turning the DMCMcoolant surge tank pressure cap
slowly, and remove it.
3. Add the pre‐mixed DEX‐COOL, available at your dealer, to the
DMCM coolant surge tank until
the level reaches the FULL
COLD mark.
4. Turn the ignition to ON/RUN without starting the engine. The
hybrid cooling pumps will run
and any trapped air will purge to
the surge tank.

affects vehicle handling and ride
comfort. Never load your vehicle
with more weight than it was
designed to carry.
When to Check
Check your tires once a month
or more.
How to Check
Use a good quality pocket-type
gauge to check tire pressure. You
cannot tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly
inflated even when they're
underinflated. Check the tire's
inflation pressure when the tires are
cold. Cold means your vehicle has
been sitting for at least three hours
or driven no more than 1.6 km
(1 mile).
Remove the valve cap from the tire
valve stem. Press the tire gauge
firmly onto the valve to get a
pressure measurement. If the cold
tire inflation pressure matches the
recommended pressure on the tireand loading information label, no
further adjustment is necessary.
If the pressure is low, add air until
you reach the recommended
amount.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge.
Be sure to put the valve caps back
on the valve stems. They help
prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly. The TPMS sensors
monitor the air pressure in the
vehicle's tires and transmit the tire
pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS will illuminate
the low tire pressure warning
symbol located on the instrument
panel cluster. If the warning light
comes on, stop as soon as possible
and inflate the tires to the
recommended pressure shown on
the tire loading information label.
See
“Vehicle Load Limits” in the
owner manual for more information.
At the same time a message to
check the pressure in a specific tire
appears on the Driver Information
Center (DIC) display. The low tire
pressure warning light and the DIC
warning message come on at each
ignition cycle until the tires are

Black plate (19,1)Chevrolet Tahoe and GMC Yukon/Yukon Denali Hybrid - 2011
Vehicle Care 10-19
inflated to the correct inflation
pressure. Using the DIC, tire
pressure levels can be viewed by
the driver. For additional information
and details about the DIC operation
and displays seeDriver Information
Center (DIC) on page 5‑11.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as you start to drive. This
could be an early indicator that the
air pressure in the tire(s) are getting
low and need to be inflated to the
proper pressure.
A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle's
original equipment tires and the
correct inflation pressure for your
vehicle's tires when they are cold.
See “Vehicle Load Limits” for an
example of the Tire and Loading
Information label and its location on
your vehicle. Also see Tire Pressure
on page 10‑17. Your vehicle's TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See
“Tire Inspection,”
“Tire Rotation” and“Tires” in the
owner manual for more information.
Notice: Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the Tire
Pressure Monitor System (TPMS)
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM approved tire sealant
available through your dealer or
included in the vehicle.
Your vehicle, when new, included a
factory‐installed Tire Sealant and
Compressor Kit. This kit uses a GM
approved liquid tire sealant. See
Tire Sealant and Compressor Kit on
page 10‑24.TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire warning light flashes for
about one minute and then stays on
for the remainder of the ignition
cycle. A DIC warning message is
also displayed. The low tire warning
light and DIC warning message
come on at each ignition cycle until
the problem is corrected. Some of
the conditions that can cause the
malfunction light and DIC message
to come on are:
.The TPMS sensor matching
process was started but not
completed or not completed
successfully after rotating the
vehicle's tires. The DIC message
and TPMS malfunction light
should go off once the TPMS
sensor matching process is
performed successfully. See
“TPMS Sensor Matching
Process” later in this section.

Black plate (20,1)Chevrolet Tahoe and GMC Yukon/Yukon Denali Hybrid - 2011
10-20 Vehicle Care
.One or more TPMS sensors are
missing or damaged. The DIC
message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer for
service.
.Replacement tires or wheels do
not match your vehicle's original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. See
“Buying New Tires”in the owner
manual.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer for service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
rotate your vehicle's tires or replace
one or more of the TPMS sensors,
the identification codes will need to
be matched to the new tire/wheel
position. The sensors are matched
to the tire/wheel positions in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear
tire using a TPMS diagnostic tool.
See your dealer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire's air pressure. If increasing the
tire's air pressure, do not exceed
the maximum inflation pressure
indicated on the tire's sidewall.
To decrease air-pressure out of a
tire you can use the pointed end of
the valve cap, a pencil-style air
pressure gauge, or a key.
You have two minutes to match
the first tire/wheel position, and
five minutes overall to match all four
tire/wheel positions. If it takes longer
than two minutes, to match the first
tire and wheel, or more than
five minutes to match all four tire
and wheel positions the matching
process stops and you need to
start over.
The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/
RUN with the engine off.
3. Press
QandKon the Remote
Keyless Entry (RKE) transmitter
at the same time for
approximately five seconds. The
horn sounds twice to signal the
receiver is in relearn mode and

Vehicle Care 10-21
TIRE LEARNING ACTIVE
message displays on the DIC
screen.
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.

2. Get the vehicles close enoughso the jumper cables can reach,
but be sure the vehicles are not
touching each other. It could
cause a ground connection you
do not want. You would not be
able to start your vehicle, and
the bad grounding could damage
the electrical systems.
To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put the automatic
transmission in P (Park) or a
manual transmission in
N (Neutral) before setting the
parking brake. If you have a
four-wheel-drive vehicle, be sure
the transfer case is in a drive
gear, not in N (Neutral). Notice:
If you leave the radio or
other accessories on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories when
jump starting the vehicle.
3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all the lamps that are not
needed.
This avoids sparks and helps
save both batteries. It could
save the radio!
4. Open the hood on the other vehicle and locate the
positive (+) and negative (−)
terminal locations on that
vehicle. Your vehicle has a remote
positive (+) and a remote
negative (−) jump starting
terminal. You should always use
these remote terminals instead
of the terminals on the battery.
If the vehicle has a remote
positive (+), it is located under a
red plastic cover at the positive
battery post. To uncover the
remote positive (+) terminal,
open the red plastic cover.
