Trip A and Trip B
The trip displays show fuel used,
average fuel economy, and distance
traveled since the last trip reset.
Reset the trip data by pressing and
holding the SELECT button when
either Trip A or Trip B is displayed.
Oil Life
This displays the percentage
of remaining oil life. The lower
the percentage, the closer the
vehicle is to needing an oil change.
When the oil life is depleted, the
CHANGE ENGINE OIL SOON
message displays. Change the oil
as soon as possible. Additional
maintenance is also recommended
in the Maintenance Schedule.
SeeScheduled Maintenance on
page 11‑2 andEngine Oil on
page 10‑12. The oil life must be reset after
each oil change. Avoid accidental
resetting of the Engine Oil Life
System. It cannot be reset
accurately until the next oil change.
To reset the Engine Oil Life System,
see
Engine Oil Life System on
page 10‑15. The system is reset
when 100% displays.
Tire Pressure
The display will show a vehicle with
the approximate pressures of all
four tires. Tire pressure is displayed
in either kilopascals (kPa) or in
pounds per square inch (psi).
If a low or high tire pressure is
detected, a message is displayed
advising to check the tire pressure
in the specified tire. See Tire
Pressure on page 10‑54 andTire
Messages on page 5‑52 for more
information.
If the tire pressure display shows
dashes instead of a value, there
may be a problem with the vehicle.
See your dealer for service. Vehicle Messages

Infotainment System 7-75
When the vehicle is not receiving
signals from the satellites, a symbol
appears on the map screen. See
Navigation Symbols on page 7‑47.
This system might not be available
or interferences can occur if any of
the following is true:
.Signals are obstructed by tall
buildings, trees, large trucks,
or a tunnel.
.Satellites are being repaired or
improved.
For more information if the GPS
is not functioning properly, see
“If the System Needs Service” and
“Problems with Route Guidance.”
Vehicle Positioning
At times, the position of the vehicle
on the map could be inaccurate
due to one or more of the following
reasons:
.The road system has changed.
.The vehicle is driving on slippery
road surfaces such as in sand,
gravel, and/or snow.
.The vehicle is traveling on
winding roads or long straight
roads.
.Approaching a tall building or a
large vehicle.
.The surface streets run parallel
to a freeway.
.The vehicle has been transferred
by a vehicle carrier or a ferry.
.The current position calibration
is set incorrectly.
.The vehicle is traveling at high
speed.
.The vehicle changes directions
more than once, or the vehicle
is turning on a turn table in a
parking lot.
.The vehicle is entering and/or
exiting a parking lot, garage,
or a lot with a roof.
.The GPS signal is not received.
.A roof carrier is installed on the
vehicle.
.Tire chains have been installed.
.The tires are replaced or worn.
.The tire pressure for the tires is
incorrect.
.This is the first navigation use
after the map data is updated.
.The 12-volt battery is
disconnected for several days.
.The vehicle is driving in heavy
traffic where driving is at low
speeds, and the vehicle is
stopped and started repeatedly.

The Tire and Loading
Information label shows the
number of occupant seating
positions (A), and the maximum
vehicle capacity weight (B) in
kilograms and pounds.
The Tire and Loading
Information label also shows
the tire size of the original
equipment tires (C) and the
recommended cold tire inflation
pressures (D). For more
information on tires and inflation
seeTires on page 10‑48 and
Tire Pressure on page 10‑54.
There is also important loading
information on the Certification
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
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.
The vehicle is neither designed
nor intended to tow a trailer.

Wheels and Tires
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.(Continued)
WARNING (Continued)
.Overloading the tires can
cause overheating as a
result of too much flexing.
There could be a blowout and
a serious crash. See Vehicle
Load Limits on page 9‑14.
.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.
(Continued)
WARNING (Continued)
.Worn or old tires can cause
a crash. If the tread is badly
worn, replace them.
.Replace any tires that have
been damaged by impacts
with potholes, curbs, etc.
.Improperly repaired tires
can cause a crash. Only the
dealer or an authorized tire
service center should repair,
replace, dismount, and mount
the tires.
.Do not spin the tires in
excess of 55 km/h (35 mph)
on slippery surfaces such
as snow, mud, ice, etc.
Excessive spinning may
cause the tires to explode.

(B) TPC Spec (Tire
Performance Criteria
Specification)
:Original
equipment tires designed to
GM's specific tire performance
criteria have a TPC specification
code molded onto the sidewall.
GM's TPC specifications meet
or exceed all federal safety
guidelines.
(C) DOT (Department
of Transportation)
:
The Department of
Transportation (DOT) code
indicates that the tire is in
compliance with the U.S.
Department of Transportation
Motor Vehicle Safety Standards.
(D) Tire Identification Number
(TIN)
:The letters and numbers
following the DOT code are
the Tire Identification Number
(TIN). The TIN shows the manufacturer and plant code,
tire size, and date the tire
was manufactured. The TIN is
molded onto both sides of the
tire, although only one side may
have the date of manufacture.
(E) Tire Ply Material
:The type
of cord and number of plies in
the sidewall and under the tread.
(F) Uniform Tire Quality
Grading (UTQG)
:Tire
manufacturers are required
to grade tires based on three
performance factors: treadwear,
traction, and temperature
resistance. For more information
see Uniform Tire Quality
Grading on page 10‑65.
(G) Maximum Cold Inflation
Load Limit
:Maximum load
that can be carried and the
maximum pressure needed
to support that load.
Tire Designations
Tire Size
The following is an example
of a typical passenger vehicle
tire size.
(A) Passenger (P‐Metric) Tire:
The United States version of
a metric tire sizing system.
The letter P as the first
character in the tire size
means a passenger vehicle
tire engineered to standards
set by the U.S. Tire and Rim
Association.
