octane rating of less than 87, as this
may cause engine knock and will
lower fuel economy.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:. For vehicles which are not
FlexFuel, fuel labeled greater
than 15% ethanol by volume,
such as mid-level ethanol
blends (16 –50% ethanol),
E85, or FlexFuel.
. Fuel with any amount of
methanol, methylal, and
aniline. These fuels can
corrode metal fuel system
parts or damage plastic and
rubber parts.
. Fuel containing metals such
as methylcyclopentadienyl
manganese tricarbonyl
(Continued)
Caution (Continued)
(MMT), which can damage
the emissions control system
and spark plugs.
. Fuel with a posted octane
rating of less than the
recommended fuel. Using this
fuel will lower fuel economy
and performance, and may
decrease the life of the
emissions catalyst.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that meet
California specifications. See the
underhood emission control label.
If this fuel is not available in states
adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting federal
specifications, but emission control
system performance may be affected.
The malfunction indicator lamp could turn on and the vehicle may not pass
a smog-check test. See
Malfunction
Indicator Lamp (Check Engine Light)
0 133. If this occurs, return to your
authorized dealer for diagnosis. If it is
determined that the condition is
caused by the type of fuel used,
repairs may not be covered by the
vehicle warranty.
Fuels in Foreign Countries
The U.S., Canada, and Mexico post
fuel octane ratings in anti-knock index
(AKI). For fuel not to use in a foreign
country, see “Prohibited Fuels” inFuel
0 236.
Fuel Additives
To keep fuel systems clean, TOP TIER
detergent gasoline is recommended.
See Fuel 0236.
If TOP TIER detergent gasoline is not
available, one bottle of GM Fuel
System Treatment Cleaner added to
the fuel tank at every engine oil
change, can help. GM Fuel System

VEHICLE CARE 287
Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires that
do not have enough air, can
result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards. 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
0 184.
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). See
Compact Spare Tire 0313. 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.

CUSTOMER INFORMATION 355
Vehicle Data Recording
and Privacy
The vehicle has a number of
computers that record information
about the vehicle’s performance and
how it is driven. For example, the
vehicle uses computer modules to
monitor and control engine and
transmission performance, to monitor
the conditions for airbag deployment
and deploy them in a crash, and,
if equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store data
to help the dealer technician service
the vehicle. Some modules may also
store data about how the vehicle is
operated, such as rate of fuel
consumption or average speed. These
modules may retain personal
preferences, such as radio presets, seat
positions, and temperature settings.
Event Data Recorders
This vehicle is equipped with an event
data recorder (EDR). The main
purpose of an EDR is to record, in
certain crash or near crash-likesituations, such as an air bag
deployment or hitting a road obstacle,
data that will assist in understanding
how a vehicle’s systems performed.
The EDR is designed to record data
related to vehicle dynamics and safety
systems for a short period of time,
typically 30 seconds or less. The EDR
in this vehicle is designed to record
such data as:
.
How various systems in your
vehicle were operating;
. Whether or not the driver and
passenger safety belts were
buckled/fastened;
. How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
. How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
Note
EDR data are recorded by your vehicle
only if a non-trivial crash situation
occurs; no data are recorded by the
EDR under normal driving conditions and no personal data (e.g., name,
gender, age, and crash location) are
recorded. However, other parties, such
as law enforcement, could combine
the EDR data with the type of
personally identifying data routinely
acquired during a crash investigation.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such as
law enforcement, that have the special
equipment, can read the information
if they have access to the vehicle or
the EDR.
GM will not access these data or share
it with others except: with the consent
of the vehicle owner or, if the vehicle
is leased, with the consent of the
lessee; in response to an official
request by police or similar
government office; as part of GM's
defense of litigation through the
discovery process; or, as required by
law. Data that GM collects or receives
may also be used for GM research
needs or may be made available to

Advanced Diagnostics provides a way
to keep up on maintenance.
Capabilities vary by model. See
www.onstar.com for details and
system limitations. Message and data
rates may apply. Advanced Diagnostics
requires an active OnStar paid service

appear on the infotainment
display. Proactive Alerts are
designed to help predict specific
types of issues based on
information collected from the
vehicle. Other factors may affect
vehicle performance. Not all issues
will deliver alerts. In some cases, a
dealer service check may be
required to confirm the accuracy
of the alerts.
. Dealer Maintenance Notification:
Have the vehicle notify your
preferred dealer when it is time for
maintenance. Your dealer will then
contact you to set up an
