9-72 Vehicle Care
{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, use a cloth or a
paper towel to do this; but be sure
to use a scraper or wire brush
later, if needed, to get all the rust
or dirt off. SeeIf a Tire Goes Flat
on page 9‑67.
9. Remove any rust or dirt from the
wheel bolts, mounting surfaces,
and spare wheel.
10. Install the compact spare tire.
{WARNING
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash. 11. Put the wheel nuts back on
with the rounded end of the
nuts toward the wheel. Turn
each nut clockwise by hand
until the wheel is held against
the hub.
12. Lower the vehicle by turning the jack handle
counterclockwise. Lower the
jack completely.
{WARNING
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. See Capacities and
Specifications
on page 11‑2for
original equipment wheel nut
torque specifications.

9-76 Vehicle Care
1. Check the other vehicle. It musthave a 12-volt battery with a
negative ground system.
Notice: If the other vehicle's
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle. 2. Position the two vehicles so that
they are not touching.
3. Set the parking brake firmly and put the shift lever in P (Park).
See Shifting Into Park
on
page 8‑23. 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.
4. Turn the ignition to LOCK/OFF
and switch off all lights and
accessories in both vehicles,
except the hazard warning
flashers if needed.
{WARNING
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.

Customer Information 12-15
Vehicle Data
Recording and
Privacy
Your GM vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven.
For example, your vehicle uses
computer modules to monitor and
control engine and transmission
performance, to monitor the
conditions for airbag deployment
and deploy airbags in a crash and,
if so equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store
data to help your dealer/retailer
technician service your vehicle.
Some modules may also store data
about how you operate the vehicle,
such as rate of fuel consumption or
average speed. These modules may
also retain the owner’s personal
preferences, such as radio pre-sets,
seat positions, and temperature
settings.
Event Data Recorders
This vehicle has an Event Data
Recorder (EDR). The main purpose
of an EDR is to record, in certain
crash or near crash-like situations,
such as an airbag 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
pressing the accelerator and/or
brake pedal
.How fast the vehicle was
traveling This data can help provide a better
understanding of the circumstances
in which crashes and injuries occur.
Important:
EDR data is recorded
by your vehicle only if a non-trivial
crash situation occurs; no data is
recorded by the EDR under normal
driving conditions and no personal
data (e.g., name, gender, age, and
crash location) is 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.

12-16 Customer Information
GM will not access this 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 of 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 others for
research purposes, where a need is
shown and the data is not tied to a
specific vehicle or vehicle owner.
OnStar®
If your vehicle has OnStar and you
subscribe to the OnStar services,
please refer to the OnStar Terms
and Conditions for information on
data collection and use. See also
OnStar
®Systemon page 4‑43in
this manual for more information.
Navigation System
If your vehicle has a navigation
system, use of the system may
result in the storage of destinations,
addresses, telephone numbers, and
other trip information. Refer to the
navigation system operating manual
for information on stored data and
for deletion instructions.
Radio Frequency
Identification (RFID)
RFID technology is used in some
vehicles for functions such as tire
pressure monitoring and ignition
system security, as well as in
connection with conveniences such
as key fobs for remote door locking/
unlocking and starting, and
in-vehicle transmitters for garage
door openers. RFID technology in
GM vehicles does not use or record
personal information or link with any
other GM system containing
personal information.
Radio Frequency
Statement
This vehicle has systems that
operate on a radio frequency that
comply with Part 15 of the Federal
Communications Commission (FCC)
Rules and with RSS-210/211 of
Industry and Science Canada.
Operation is subject to the following
two conditions:
1. The device may not cause interference.
2. The device must accept any interference received, including
interference that may cause
undesired operation of the
device.
Changes or modifications to any of
these systems by other than an
authorized service facility could void
authorization to use this equipment.
