Steering Column Lock
If equipped, the steering
column lock is a
theft-deterrent device. This
feature locks the steering
column when the vehicle is
turned off and the driver door
is opened, or when the driver
door is opened and then the
vehicle is turned off. The
steering column unlocks when
the vehicle is turned on.
The Driver Information Center
(DIC) may display one of these
messages:
.A message to service the
steering column lock
indicates that an issue has
been detected with the
column lock feature and the
vehicle should be serviced.
.A message that the steering
column is locked indicates
that the engine is running,
but the steering column is
still locked. It is normal for
the column to be locked
during a remote start, but
the column should unlockafter the brake pedal is
pressed and the vehicle is
started. No message will
display during a remote
start.
.A message that the steering
wheel must be turned and
the vehicle must be started
again indicates that the
column lock mechanism is
bound, the column locking
device was unable to unlock
the steering column, and the
vehicle did not start. If this
happens, immediately turn
the steering wheel from side
to side to unbind the column
lock. If this does not unlock
the steering column, turn the
vehicle off and open the
driver door to reset the
system. Then turn the
vehicle on and immediately
turn the steering wheel side
to side for about 15 seconds.
In some cases, it may take
significant force to unbind
the column.
To keep the steering column
from binding, straighten the
front wheels before turning
off the vehicle.Immobilizer

When the system has
calculated that oil life has been
diminished, it indicates that an
oil change is necessary.
A CHANGE ENGINE OIL
SOON message comes on.
Change the oil as soon as
possible within the next
1 000 km (600 mi). It is
possible that, if driving under
the best conditions, the oil life
system might indicate that an
oil change is not necessary for
up to a year. The engine oil
and filter must be changed at
least once a year and at this
time the system must be
reset. Your dealer has trained
service people who will
perform this work and reset
the system. It is also important
to check the oil regularly over
the course of an oil drain
interval and keep it at the
proper level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km
(3,000 mi) since the last oilchange. Remember to reset
the oil life system whenever
the oil is changed.
How to Reset the Engine
Oil Life System
Reset the system whenever
the engine oil is changed so
that the system can calculate
the next engine oil change. To
reset the system:
1. Using the DIC buttons, display REMAINING OIL
LIFE on the DIC. See Driver
Information Center (DIC)
(Base Level) 0136 or

2. Press and hold the thumbwheel on the
steering wheel. When the
confirmation message
displays, select YES. The
oil life will change to 100%.
Be careful not to reset the
oil life display accidentally
at any time other than
after the oil is changed. It cannot be reset
accurately until the next oil
change.
The oil life system can also be
reset as follows: 1. Using the DIC buttons, display REMAINING OIL
LIFE on the DIC. See Driver
Information Center (DIC)
(Base Level) 0136 or
Driver Information Center
(DIC) (Uplevel) 0139.
2. Fully press and release the accelerator pedal three
times within five seconds.
If the CHANGE ENGINE
OIL SOON message is not
on, the system is reset.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off.
If the CHANGE ENGINE OIL
SOON message comes back
on when the vehicle is started,
the engine oil life system has
not been reset. Repeat the
procedure.

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 unauthorizedelectronic 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 or
connect 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

Event Data Recorders
This vehicle is equipped with
an Event Data Recorder (EDR).
The main purpose of an EDR isto 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.
