the warranty manual for
information regarding the tire
warranty and where to get
service. For additional
information refer to the tire
manufacturer.
{Warning
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a
result of too much flexing.
There could be a blowout

The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity. See
Vehicle Load Limits on
page 9-10.
How the vehicle is loaded
affects vehicle handling and ride
comfort. Never load the vehicle
with more weight than it was
designed to carry.
When to Check
Check the tires once a month or
more. Do not forget the compact
spare, if the vehicle has one.
The cold compact spare tire
pressure should be at 420 kPa
(60 psi). SeeCompact Spare
Tire on page 10-61. How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
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 Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
inflation pressure is high, press
on the metal stem in the center
of the tire valve to release air.Recheck the tire pressure with
the tire gauge.
Return the valve caps on the
valve stems to prevent leaks
and keep out dirt and moisture.
Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or

Black plate (45,1)Buick Encore Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
7707490) - 2015 - crc - 2/4/15
Vehicle Care 10-45
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure telltale when one or more
of your tires is significantly
under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat and can
lead to tire failure. Under-inflation
also reduces fuel efficiency and tire
tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation hasnot reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle toensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.
See
Tire Pressure Monitor
Operation on page 10-45.
See Radio Frequency Statement on
page 13-12.
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, excluding the spare tire
and wheel assembly. The TPMS
sensors monitor the air pressure in
the tires and transmit the tire
pressure readings to a receiver
located in the vehicle.

7707490) - 2015 - crc - 2/4/15
10-46 Vehicle Care
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument cluster.
If the warning light comes on, stop
as soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. SeeVehicle Load
Limits on page 9-10.
A message to check the pressure in
a specific tire may display in the
Driver Information Center (DIC). The
low tire pressure warning light and
the DIC warning message,
if equipped, come on at each
ignition cycle until the tires are
inflated to the correct inflation
pressure. Using the DIC, it may be
possible to view the tire pressure
levels. For additional information and details about the DIC operation
and displays, see
Driver Information
Center (DIC) on page 5-22.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the
air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information label
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See Vehicle Load
Limits on page 9-10, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10-43.
The TPMS can warn about a low
tire pressure condition, but it does
not replace normal tire
maintenance. See Tire Inspection
on page 10-49, Tire Rotation on
page 10-49, and Tires on
page 10-35.
{Caution
Tire sealant materials are not all
the same. A non-approved tire
sealant could damage the 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.

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 pressure warning light,
defined above, flashes for about
one minute and then stays on for
the remainder of the ignition cycle.
A DIC warning message may also
display. The malfunction light and
DIC warning message, if equipped,
come on at each ignition cycle until
the problem is corrected. Some of
the conditions that can cause these
to come on are:
.One of the road tires has been
replaced with the spare tire. The
spare tire does not have a
TPMS sensor. The malfunction
light and the DIC message,
if equipped, should go off after
the road tire is replaced and the
sensor matching process is
performed successfully. See
"TPMS Sensor Matching
Process" later in this section.
.The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tires. The
malfunction light and the DIC
message, if equipped, should go
off after successfully completing
the sensor matching process.
See "TPMS Sensor Matching
Process" later in this section.
.One or more TPMS sensors are
missing or damaged. The
malfunction light and the DIC
message, if equipped, 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 the original equipment
tires or wheels. Tires and wheels
other than those recommended
could prevent the TPMS from
functioning properly. SeeBuying
New Tires on page 10-51.
.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
properly, it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message, if equipped,
come on and stay on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
vehicle’s tires or replacing one or
more of the TPMS sensors. Also,
the TPMS sensor matching process
should be performed after replacing
a spare tire with a road tire
containing the TPMS sensor. The
malfunction light and the DIC
message, if equipped, should go off
at the next ignition cycle. The
sensors are matched to the tire/

wheel positions, using a TPMS
relearn tool, in the following order:
driver side front tire, passenger side
front tire, passenger side rear tire,
and driver side rear. See your
dealer for service or to purchase a
relearn tool. A TPMS relearn tool
can also be purchased. See Tire
Pressure Monitor Sensor Activation
Tool at
www.gmtoolsandequipment.com or
call 1-800-GM TOOLS
(1-800-468-6657).
There are two minutes to match the
first tire/wheel position, and
five minutes overall to match all four
tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN withthe engine off. 3. Use the MENU button to select
the Vehicle Information Menu
(Menu 2) in the Driver
Information Center (DIC).
4. Use the thumbwheel (or up and down arrows) to scroll to the Tire
Pressure Menu Item screen.
5. Press and hold the SET/CLR button to begin the sensor
matching process.
A message requesting
acceptance of the process may
display.
6. If requested, press the SET/CLR button again to confirm the
selection.
The horn sounds twice to signal
the receiver is in relearn mode
and the TIRE LEARN or TIRE
LEARNING ACTIVE message
displays on the DIC screen.
7. Start with the driver side front tire.
8. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button to activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.
9. Proceed to the passenger side front tire, and repeat the
procedure in Step 8.
10. Proceed to the passenger side rear tire, and repeat the
procedure in Step 8.
11. Proceed to the driver side rear tire, and repeat the procedure
in Step 8. 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 LEARN or
TIRE LEARNING ACTIVE
message on the DIC display
screen goes off.
12. Turn the ignition to LOCK/OFF.
