Maintenance
Schedule
Tire Rotation and
Required Services Every
12 000 km (7,500 mi)
Tires are rotated to achieve a
more uniform wear for all tires.
The first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as
soon as possible, check for
proper tire inflation pressure,
and check for damaged tires
or wheels. If the unusual wear
continues after the rotation,
check the wheel alignment.
See When It Is Time for New
Tires0394 and
Wheel Replacement 0399.

Every 12 000 km (7,500 mi)
.Check the engine oil level
and oil life percentage.
If needed, change engine the
oil and filter, and reset oil the
life system. Or when the
CHANGE ENGINE OIL SOON
message displays, have the
engine oil and filter changed
within the next 1 000 km/
600 mi. If driven under the
best conditions, the engine
oil life system may not
indicate the need for vehicle
service for up to a year. The
engine oil and filter must be
changed at least once a year
and the oil life system must
be reset. Your trained dealer
technician can perform this
work. If the engine oil life
system is reset accidentally,
service the vehicle within
5 000 km/3,000 mi since the
last service. Reset the oil life system when the oil is
changed. See Engine Oil Life
System
0348.
.When the REPLACE AT
NEXT OIL CHANGE
message displays, the engine
air filter should be replaced
at the next engine oil
change. When the REPLACE
ENGINE AIR FILTER SOON
message displays, the engine
air filter should be replaced
at the earliest convenience.
Reset the engine air filter life
system after the engine air
filter is replaced. See Engine
Air Filter Life System 0349.
Every 36 000 km (22,500 mi)
.Replace the passenger
compartment air filter. Or

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 or used. 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 or to help
GM improve safety or
features. 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.
Cybersecurity
GM collects information about
the use of your vehicle
including operational and
safety related information. We
collect this information to

provide, evaluate, improve, and
troubleshoot our products and
services and to develop new
products and services. The
protection of vehicle
electronics systems and
customer data from
unauthorized outside
electronic access or control is
important to GM. GM
maintains appropriate security
standards, practices,
guidelines and controls aimed
at defending the vehicle and
the vehicle service ecosystem
against unauthorized
electronic access, detecting
possible malicious activity in
related networks, and
responding to suspected
cybersecurity incidents in a
timely, coordinated and
effective manner. Security
incidents could impact your
safety or compromise your
private data. To minimize
security risks, please do not
connect your vehicle
electronic systems to
unauthorized devices orconnect your vehicle to any
unknown or untrusted
networks (such as Bluetooth,
WIFI or similar technology). In
the event you suspect any
security incident impacting
your data or the safe
operation of your vehicle,
please stop operating your
vehicle and contact your
dealer.
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-like situations, 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
