of the engine is disabled due to the
electronic throttle control system.
Have the vehicle serviced by your
dealer immediately.
This message only appears while
the ignition is in ON/RUN, and will
not disappear until the problem is
resolved.
This message cannot be
acknowledged.
Tire Messages
CHECK TIRE PRESSURE or
TIRE LOW ADD AIR TO TIRE
If the vehicle has the Tire Pressure
Monitor System (TPMS), this
message displays when thepressure in one or more of the tires
is low. The low tire pressure warning
light will also come on. See
Tire
Pressure Light on page 5‑22. This
message will also indicate which tire
needs to be checked. You can
receive more than one tire pressure
message at a time. To read the
other messages that may have been
sent at the same time, press the set/
reset button. If a tire pressure
message appears on the DIC, stop
as soon as you can. Have the tire
pressures checked and set to those
shown on the Tire Loading
Information label. See Tires on
page 10‑43, Vehicle Load Limits on
page 9‑10, and Tire Pressure on
page 10‑52. The DIC also shows
the tire pressure values. See Driver
Information Center (DIC) on
page 5‑24.
SERVICE TIRE MONITOR
SYSTEM
If the vehicle has the Tire Pressure
Monitor System (TPMS), this
message displays if a part on the system is not working properly. The
tire pressure light also flashes and
then remains on during the same
ignition cycle. See
Tire Pressure
Light on page 5‑22. Several
conditions may cause this message
to appear. See Tire Pressure
Monitor Operation on page 10‑54 for
more information. If the warning
comes on and stays on, there may
be a problem with the TPMS. See
your dealer.
TIRE LEARNING ACTIVE
If the vehicle has the Tire Pressure
Monitor System (TPMS), this
message displays when the system
is re-learning the tire positions on
the vehicle. See Driver Information
Center (DIC) on page 5‑24 for more
information. The tire positions must
be re-learned after rotating the tires
or after replacing a tire or sensor.
See Tire Inspection on page 10‑57,
Tire Rotation on page 10‑58, Tire
Pressure Monitor Operation on
page 10‑54, and Tire Pressure on
page 10‑52 for more information.

positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading
Information label also shows the
size of the original equipment
tires (3) and the recommended
cold tire inflation pressures (4).
For more information on tires
and inflation seeTires on
page 10‑43 andTire Pressure
on page 10‑52.
There is also important loading
information on the vehicle
Certification/Tire label. It tells
you the Gross Vehicle Weight
Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for
the front and rear axle. See
“Certification/Tire Label” later in
this section.Steps for Determining Correct
Load Limit
1.
Locate the statement “The
combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs” on your vehicle's
placard.
2.Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from XXX kg or
XXX lbs.
4.The resulting figure equals
the available amount of cargo
and luggage load capacity.
For example, if the “XXX”
amount equals 1400 lbs and
there will be five 150 lb
passengers in your vehicle,
the amount of available cargo and luggage load capacity is
650 lbs (1400
−750 (5 x 150)
= 650 lbs).
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing
a trailer, the load from your
trailer will be transferred to
your vehicle. Consult this
manual to determine how this
reduces the available cargo
and luggage load capacity of
your vehicle. See Trailer
Towing on page 9‑49 for
important information on
towing a trailer, towing safety
rules and trailering tips.

Driving and Operating 9-13
Refer to the vehicle tire and
loading information label for
specific information about the
vehicle's capacity weight and
seating positions. The combined
weight of the driver, passengers,
and cargo should never exceed
the vehicle capacity weight.
Certification/Tire Label
A vehicle specific Certification/
Tire label is found on the rear
edge of the driver door. The
label shows the size of thevehicle's original tires and the
inflation pressures needed to
obtain the gross weight capacity
of the vehicle. This is called
Gross Vehicle Weight Rating
(GVWR). The GVWR includes
the weight of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label also
tells you the maximum weights
for the front and rear axles,
called Gross Axle Weight Rating
(GAWR). To find out the actual
loads on the front and rear
axles, you need to go to a weigh
station and weigh the vehicle.
Your dealer can help you with
this. Be sure to spread out the
load equally on both sides of the
centerline.
Never exceed the GVWR for the
vehicle, or the GAWR for either
the front or rear axle.
If there is a heavy load, it should
be spread out.
{WARNING
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
shorten the life of the vehicle.

Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer. See
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
(Continued)
WARNING (Continued) and a serious crash. See
Vehicle Load Limits on
page 9‑10.
.Underinflated tires pose
the same danger as
overloaded tires. The
resulting crash could
cause serious injury.
Check all tires frequently
to maintain the
recommended pressure.
Tire pressure should be
checked when the tires
are cold.
.Overinflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact —such as when
hitting a pothole. Keep
tires at the recommended
pressure.
