Driving and Operating 9-3
{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.
Defensive Driving
Defensive driving means “always
expect the unexpected.” The first
step in driving defensively is to wear
the safety belt. See Safety Belts on
page 3-10.
.Assume that other road users
(pedestrians, bicyclists, and
other drivers) are going to be
careless and make mistakes.
Anticipate what they might do
and be ready.
.Allow enough following distance
between you and the driver in
front of you.
.Focus on the task of driving.
Drunk Driving
Death and injury associated with
drinking and driving is a global
tragedy.
{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious —or even
fatal —collision if you drive after
drinking.
Do not drink and drive or ride with
a driver who has been drinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle
Braking, steering, and accelerating
are important factors in helping to
control a vehicle while driving.
Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average driver reaction time is
about three-quarters of a second. In
that time, a vehicle moving at
100 km/h (60 mph) travels 20 m
(66 ft), which could be a lot of
distance in an emergency.
Helpful braking tips to keep in mind
include:
.Keep enough distance between
you and the vehicle in front
of you.
.Avoid needless heavy braking.
.Keep pace with traffic.

Customer Information 13-15
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 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 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 others for
research purposes, where a need is
shown and the data is not tied to a
specific vehicle or vehicle owner.
OnStar®
If the vehicle is equipped with
OnStar®and has an active
subscription, additional data may be
collected through the OnStar
system. This includes information
about the vehicle’s operation;
collisions involving the vehicle; the
use of the vehicle and its features;
and, in certain situations, the
location and approximate GPS
speed of the vehicle. Refer to the OnStar Terms and Conditions and
Privacy Statement on the OnStar
website.
Infotainment System
If the vehicle is equipped with a
navigation system as part of the
infotainment system, use of the
system may result in the storage of
destinations, addresses, telephone
numbers, and other trip information.
See the infotainment manual for
information on stored data and for
deletion instructions.
