214 Infotainment System
When Teen Driver is Active:
.If equipped, the radio will
mute when the driver seat
belt, and in some vehicles
the front passenger seat
belt, is not buckled. The
audio from any device paired
to the vehicle will also be
muted.
.An object placed on the
front passenger seat, such
as a briefcase, handbag,
grocery bag, laptop, or other
electronic device, could
cause the passenger
sensing system to falsely
sense an unbuckled front
passenger and mute the
radio. If this happens,
remove the object from the
seat. See Passenger
Sensing System066.
.Some safety systems, such
as Automatic Emergency
Braking, if equipped, cannot
be turned off.
.The gap setting for Adaptive
Cruise Control and alert
timing for Forward Collision
Alert, if equipped, cannot be
changed.
.When trying to change a
safety feature that is not
configurable in Teen Driver,
the feature may be grayed
out or removed from the
infotainment menu, or the
DIC will display a message
indicating that Teen Driver is
active and the action is not
available.
.Super Cruise, if equipped, is
not available.
.Enhanced Low Fuel Warning
(if equipped) –When the
vehicle is low on fuel, the low
fuel light on the instrument
cluster flashes and the DIC
low fuel warning cannot be
dismissed.
.Do not tow a trailer if
equipped with Automatic
Emergency Braking. Report Card
The vehicle owner must
secure the driver’s consent to
record certain vehicle data
when the vehicle is driven with
a registered Teen Driver key.
There is one Report Card per
vehicle. Data is only recorded
when a registered Teen Driver
key is used to operate the
vehicle.
The Report Card data is
collected from the time Teen
Driver is activated or the last
time the Report Card was
reset. The following items may
be recorded:
.Distance Driven
–the total
distance driven.
.Maximum Speed –the
maximum vehicle speed
detected.
.Overspeed Warnings –the
number of times the speed
warning setting was
exceeded.

Driving and Operating 235
.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.
Defensive Driving
Defensive driving means
“always expect the
unexpected.” The first step in
driving defensively is to wear
the seat belt. See Seat Belts
0 49.
.Assume that other road
users (pedestrians,
bicyclists, and other drivers)
are going to be careless and
make mistakes. Anticipate
what they may do and be
ready.
.Allow enough following
distance between you and
the driver in front of you.
.Focus on the task of driving.
Impaired Driving
Death and injury associated
with impaired driving is a
global tragedy.
{Warning
Drinking alcohol or taking
drugs and then driving is
very dangerous. Your
reflexes, perceptions,
attentiveness, and judgment
can be affected by even a
small amount of alcohol or
drugs. You can have a
(Continued)
Warning (Continued)
serious—or even fatal —
collision if you drive after
drinking or taking drugs.
Do not drive while under the
influence of alcohol or drugs,
or ride with a driver who has
been drinking or is impaired
by drugs. Find alternate
transportation home; or if
you are with a group,
designate a driver who will
remain sober.
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.

Warning (Continued)
perform these procedures
properly could cause
malfunction, potentially
resulting in death, personal
injury, or damage to the
vehicle or property. Do not
attempt to perform these
adjustments or procedures
unless properly qualified.
{Warning
Prior to each track event
and again before returning
to public roads, tighten the
wheel nuts with a torque
wrench to the proper torque
specification. Wheel nuts
that are improperly or
incorrectly tightened can
cause the wheels to become
loose or come off, resulting
in a crash. See Capacities
and Specifications0480 for
wheel nut torque
specifications.
Caution
Low oil levels can damage
the engine. If using the
vehicle for competitive
driving, the engine may use
more oil than it would with
normal use. Check the oil
level often during
competitive driving.
Competitive Driving Mode can
be selected. See Driver Mode
Control 0292.
Seat Belts
Lap-Shoulder Belt
If equipped, the driver seat
belt has an Automatic Locking
Retractor (ALR). This feature
is useful in performance
driving scenarios where the
driver wants to be held in the
seat more tightly to take
advantage of the aggressive
bolstering of the seat.
1. Move the seat 8-10 cm (3-4 in) rearward from the
normal driving position. 2. Pull the driver shoulder
belt out as far as it will go,
until it stops, to set the
lock. While holding the
shoulder belt in this
position, buckle the belt.
When the shoulder belt is
released, the retractor will
make a ratchet sound
when it retracts. When the
retractor lock is set, the
belt can be tightened but
not pulled out of the
retractor.
3. Adjust the belt, and then move the seat forward
8-10 cm (3-4 in) to the
desired driving position.
This will secure the belt.
The belt fit should be tight,
but not uncomfortable.
To unlatch the belt, press
the button on the buckle.
The belt should return to
its stowed position.

{Warning
Do not rely on this feature.
It does not replace the need
to pay attention and drive
safely. You may not hear or
feel alerts or warnings
provided by this system.
Failure to use proper care
when driving may result in
injury, death, or vehicle
damage.
When Automatic Vehicle Hold
(AVH) is turned on and the
vehicle is braked to a stop,
AVH prevents the vehicle from
moving during the transition
from brake pedal release to
accelerator pedal apply. The
brakes release when the
accelerator pedal is applied.
The brakes may also release
under other conditions. Do not
rely on AVH to hold the
vehicle.
If the accelerator pedal is not
applied within a few minutes,
the Electric Parking Brake will apply. The parking brake will
also apply if the driver door is
opened or the driver seat belt
is unfastened while AVH is
holding the vehicle.
AVH can be turned on by
pressing AUTO HOLD. The
indicator light on the switch
will come on. The AVH light on
the instrument panel will come
on while AVH is actively
holding the vehicle. See
Automatic Vehicle Hold (AVH)
Light
0122.
Ride Control
Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction
Control System (TCS) and
StabiliTrak/Electronic Stability
Control (ESC). These systems
help limit wheel slip and assist the driver in maintaining
control, especially on slippery
road conditions.
TCS activates if it senses that
any of the drive wheels are
spinning or beginning to lose
traction. When this happens,
the system brakes the
spinning wheel(s) and/or
reduces engine power to limit
wheel spin.
StabiliTrak/ESC activates
when the computer senses a
difference between the
intended path and the
direction the vehicle is actually
traveling. StabiliTrak/ESC
selectively applies braking
pressure at any one of the
vehicle's brakes to help steer
the vehicle in the intended
direction.
If cruise control is being used
and TCS or StabiliTrak/ESC
begins to limit wheel spin,
cruise control will disengage.
Cruise control may be turned
back on when road conditions
allow.

dangerous. Do not leave the
vehicle while it is being held
at a stop by ACC. Always
place the vehicle in P (Park)
and turn off the ignition
before leaving the vehicle.
ACC Override
If using the accelerator pedal
while ACC is active, the ACC
indicator turns blue on the
instrument cluster and in the
HUD (if equipped) to indicate
that automatic braking will not
occur. ACC will resume operation when the
accelerator pedal is not being
pressed.
{Warning
The ACC will not
automatically apply the
brakes if your foot is resting
on the accelerator pedal.
You could crash into a
vehicle ahead of you.
Curves in the Road
{Warning
On curves, ACC may not
detect a vehicle ahead in
your lane. You could be
startled if the vehicle
