204 DRIVING AND OPERATING
Driving for Better Fuel
Economy
Driving habits can affect fuel mileage.
Here are some driving tips to get the
best fuel economy possible.
.Set the climate controls to the
desired temperature after the engine
is started, or turn them off when
not required.
.On AWD vehicles, use Tour Mode
when conditions permit.
.Avoid fast starts and accelerate
smoothly.
.Brake gradually and avoid abrupt
stops.
.Avoid idling the engine for long
periods of time.
.When road and weather conditions
are appropriate, use cruise control.
.Always follow posted speed limits or
drive more slowly when conditions
require.
.Keep vehicle tires properly inflated.
.Combine several trips into a
single trip.
.Replace the vehicle's tires with the
same TPC Spec number molded into
the tire's sidewall near the size.
.Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms and
can take your focus from the task of
driving. Exercise good judgment and
do not let other activities divert your
attention away from the road. Many
local governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, keep your
eyes on the road, keep your hands on
the steering wheel, and focus your
attention on driving.
.Do not use a phone in demanding
driving situations. Use a hands-free
method to place or receive
necessary phone calls.
.Watch the road. Do not read, take
notes, or look up information on
phones or other electronic devices.
.Designate a front seat passenger to
handle potential distractions.
.Become familiar with vehicle
features before driving, such as
programming favorite radio stations
and adjusting climate control and
seat settings. Program all trip
information into any navigation
device prior to driving.
.Wait until the vehicle is parked to
retrieve items that have fallen to
the floor.
.Stop or park the vehicle to tend to
children.
.Keep pets in an appropriate carrier
or restraint.
.Avoid stressful conversations while
driving, whether with a passenger or
on a cell phone.
{Warning
Taking your eyes off the road too
long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving.
Refer to the infotainment section for
more information on using that
system and the navigation system,
if equipped, including pairing and
using a cell phone.

DRIVING AND OPERATING 241
Ending Cruise Control
There are four ways to end cruise
control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to
N (Neutral).
.PressJ.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if the
ignition is turned off.
Adaptive Cruise Control
(Advanced)
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed and
following gap. Read this entire section
before using this system. The
following gap is the following time
between your vehicle and a vehicle
detected directly ahead in your path,
moving in the same direction. If no
vehicle is detected in your path, ACC works like regular cruise control. ACC
uses camera and radar sensors. See
Radio Frequency Statement
0393.
If a vehicle is detected in your path,
ACC can apply acceleration or limited,
moderate braking to maintain the
selected following gap. To disengage
ACC, apply the brake. If ACC is
controlling your vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates, the ACC may
automatically disengage. See Traction
Control/Electronic Stability Control
0 235. When road conditions allow
ACC to be safely used, the ACC can be
turned back on.
Disabling the TCS or StabiliTrak/ESC
system will disengage and prevent
engagement of ACC.
ACC can reduce the need for you to
frequently brake and accelerate,
especially when used on expressways,
freeways, and interstate highways.
When used on other roads, you may
need to take over the control of
braking or acceleration more often. ACC automatically slows the vehicle
down while navigating the curve and
may increase speed out of the curve,
but will not exceed the set speed.
{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver”
in this section.
Complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0205.

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 servicethe 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 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 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:
