Attention to the Road
{Warning
Super Cruise is a driver
assistance system and
cannot accurately detect or
predict all situations. Super
Cruise is not a crash
avoidance system. To
prevent serious injury or
death, you must supervise
the driving task and monitor (Continued)

the road conditions. You
may need to respond to
traffic events by steering,
braking, or accelerating. See
Defensive Driving0235.
Super Cruise also cannot
determine whether you are
awake, asleep, impaired,
or properly focused on safe
driving. The vehicle could
crash into other vehicles,
drive out of the lane, or drive
off the road. Complete
attention is always required
while driving, even while
using Super Cruise. Be
prepared to take over
steering or apply the brakes
at any time.
{Warning
To prevent serious injury or
death, be alert and pay
special attention when
passing highway exits,
entrances, and crossings
with Super Cruise, and be
ready to take control of the
vehicle when necessary.
Changes in lane markings
around exits and entrances
can momentarily cause
Super Cruise to not detect
the correct lane. If this
occurs, Super Cruise may
attempt steering inputs to
bring the vehicle back into
the correct lane and, in rare
circumstances, could
over-correct and cause the
vehicle to momentarily cross
into a lane next to your
vehicle unless you manually
steer to maintain your lane
position. The Driver Attention System
(DAS) on the steering column
continually monitors driver
head and eye position to
estimate driver attention to
the road. The camera does not
record or share pictures,
audio, or video.
Sunglasses, hats, or other
types of clothing that change
the shape of the head may
interfere with camera
performance. To improve
camera performance, raise or
lower the steering wheel,
or change the seat position.

Assistance Systems
for Driving
If equipped, when driving the
vehicle in a forward gear,
Forward Collision Alert (FCA),
Lane Departure Warning
(LDW), Lane Keep Assist (LKA), Side Blind Zone Alert
(SBZA), Lane Change Alert
(LCA), Automatic Emergency
Braking (AEB), and/or the
Front Pedestrian Braking
(FPB) System can help to
avoid a crash or reduce crash
damage.
Forward Collision
Alert (FCA) System
The FCA system may help to
avoid or reduce the harm
caused by front-end crashes.
When approaching a vehicle
ahead too quickly, FCA
provides a red flashing alert
on the windshield and rapidly
beeps or pulses the driver
seat. FCA also lights an amber
visual alert if following another
vehicle much too closely.
FCA detects vehicles within a
distance of approximately
60 m (197 ft) and operates at
speeds above 8 km/h (5 mph).
If the vehicle has Adaptive
Cruise Control (ACC), it can
detect vehicles to distances of
approximately 110 m (360 ft)
and operates at all speeds.
See Adaptive Cruise Control
(Advanced)
0304.
{Warning
FCA is a warning system and
does not apply the brakes.
When approaching a
slower-moving or stopped
vehicle ahead too rapidly,
or when following a vehicle
too closely, FCA may not
provide a warning with
enough time to help avoid a
crash. It also may not
provide any warning at all.
FCA does not warn of
pedestrians, animals, signs,
guardrails, bridges,
construction barrels,
or other objects. Be ready to
take action and apply the
brakes. See Defensive
Driving 0235.
FCA can be disabled through
vehicle personalization. To

deceleration. Continue to
apply the brake pedal as
needed.
Tailgating Alert
The vehicle ahead indicator
will display amber when you
are following a vehicle ahead
much too closely.
Selecting the Alert Timing
The Collision Alert control is
on the steering wheel. Press
[to set the FCA timing to
Far, Medium, or Near. The first
button press shows the
current setting on the DIC. Additional button presses will
change this setting. The
chosen setting will remain until
it is changed and will affect
the timing of both the Collision
Alert and the Tailgating Alert
features. The timing of both
alerts will vary based on
vehicle speed. The faster the
vehicle speed, the farther
away the alert will occur.
Consider traffic and weather
conditions when selecting the
alert timing. The range of
selectable alert timings may
not be appropriate for all
drivers and driving conditions.
If your vehicle is equipped with
Adaptive Cruise Control (ACC),
changing the FCA timing
setting automatically changes
the following gap setting (Far,
Medium, or Near).
Following Distance
Indicator
The following distance to a
moving vehicle ahead in your
path is indicated in following
time in seconds on the DriverInformation Center (DIC). See
Driver Information Center
(DIC) (Base Level)
0129 or
Driver Information Center
(DIC) (Uplevel) 0132. The
minimum following time is
0.5 seconds away. If there is
no vehicle detected ahead,
or the vehicle ahead is out of
sensor range, dashes will be
displayed.
Unnecessary Alerts
FCA may provide unnecessary
alerts for turning vehicles,
vehicles in other lanes, objects
that are not vehicles,
or shadows. These alerts are
normal operation and the
vehicle does not need service.
Cleaning the System
If the FCA system does not
seem to operate properly, this
may correct the issue:
.Clean the outside of the
windshield in front of the
rearview mirror.
.Clean the entire front of the
vehicle.

Warning (Continued)
while towing to make sure it
is within the same lane as
the tow vehicle.
How the System Works
LKA uses a camera sensor
installed on the windshield
ahead of the rearview mirror
to detect lane markings. It may
provide brief steering assist if
it detects an unintended lane
departure. It may further
provide an audible alert or the
driver seat may pulse
indicating that a lane marking
has been crossed. The system
does not provide a Lane
Departure Warning (LDW)
when intentionally steering
across a lane marker.
To turn LKA on and off, press
Aon the center stack.
If equipped, the indicator light
on the button comes on when
LKA is on and turns off when
LKA is disabled. In some vehicles, a long press of over
three seconds is required to
turn LKA off.
When on,
Ais white,
if equipped, indicating that the
system is not ready to assist.
Ais green if LKA is ready to
assist. LKA may assist by
gently turning the steering
wheel if the vehicle
approaches a detected lane
marking.
Ais amber when
assisting. It may also provide a
Lane Departure Warning
(LDW) alert by flashing
A
amber if the vehicle crosses a
detected lane marking.
Additionally, there may be
three beeps, or the driver seat
may pulse three times, on the
right or left, depending on the
lane departure direction.
Take Steering
The LKA system does not
continuously steer the vehicle.
If LKA does not detect active
driver steering, an alert and
chime may be provided. Steer the vehicle to dismiss. LKA
may become temporarily
unavailable after repeated
take steering alerts.
When the System Does
Not Seem to Work
Properly
The system performance may
be affected by:
.Close vehicles ahead.
.Sudden lighting changes,
such as when driving
through tunnels.
.Banked roads.
.Roads with poor lane
markings, such as two-lane
roads.
If the LKA system is not
functioning properly when lane
markings are clearly visible,
cleaning the windshield
may help.
A camera blocked message
may display if the camera is
blocked. Some driver
assistance systems may have
reduced performance or not

damaged, and the repairs
would not be covered by the
vehicle warranty. Pull a
trailer only if all the steps in
this section have been
followed. Ask your dealer for
advice and information
about towing a trailer with
the vehicle.
Driving with a Trailer
Trailering is different than just
driving the vehicle by itself.
Trailering means changes in
handling, acceleration, braking,
durability, and fuel economy.
Successful, safe trailering
takes correct equipment, and
it has to be used properly.
The following information has
many time-tested, important
trailering tips and safety rules.
Many of these are important
for your safety and that of
your passengers. Read this
section carefully before pulling
a trailer.When towing a trailer:
.Become familiar with, and
follow all state and local laws
that apply to trailer towing.
These requirements vary
from state to state.
.State laws may require the
use of extended side view
mirrors. If your visibility is
limited or restricted while
towing, install extended side
view mirrors on your vehicle,
even if not required.
.Do not tow a trailer during
the first 800 km (500 mi) of
vehicle use to prevent
damage to the engine, axle,
or other parts.
.Perform the first oil change
before heavy towing.
.Do not drive over 800 km/h
(50 mph) and do not make
starts at full throttle during
the first 800 km (500 mi) of
trailer towing.
.Tow in D (Drive). If the
transmission downshifts too
often, a lower gear may be
selected using Manual Mode.
See Manual Mode
(Electronic Shifter)
0281 or
Manual Mode (Mechanical
Shifter) 0280.
If equipped, the following
driver assistance features
should be turned off when
towing a trailer:

Engine Oil
To ensure proper engine
performance and long life,
careful attention must be paid
to engine oil. Following these
simple, but important steps
will help protect your
investment:
.Use engine oil approved to
the proper specification and
of the proper viscosity
grade. See “Selecting the
Right Engine Oil” in this
section.
.Check the engine oil level
regularly and maintain the
proper oil level. See
“Checking Engine Oil” and
“When to Add Engine Oil” in
this section.
.Change the engine oil at the
appropriate time. See Engine
Oil Life System 0381.
.Always dispose of engine oil
properly. See “What to Do
with Used Oil” in this section.
Checking Engine Oil
Check the engine oil level
regularly, every 650 km
(400 mi), especially prior to a
long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment
Overview0373 for the
location.
{Warning
The engine oil dipstick
handle may be hot; it could
burn you. Use a towel or
glove to touch the dipstick
handle.
If a low oil Driver Information
Center (DIC) message displays,
check the oil level.

manufacturer's warnings
about the use and disposal of
oil products.
Used oil can be a threat to the
environment. If you change
your own oil, be sure to drain
all the oil from the filter before
disposal. Never dispose of oil
by putting it in the trash or
pouring it on the ground, into
sewers, or into streams or
bodies of water. Recycle it by
taking it to a place that
collects used oil.
Engine Oil Life
System
When to Change
Engine Oil
This vehicle has a computer
system that indicates when to
change the engine oil and
filter. This is based on a
combination of factors which
include engine revolutions,
engine temperature, and miles
driven. Based on driving
conditions, the mileage atwhich an oil change is
indicated can vary
considerably. For the oil life
system to work properly, the
system must be reset every
time the oil is changed.
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 oil
change. 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) 0129 or
Driver Information Center
(DIC) (Uplevel) 0132.
2. Press and hold the thumbwheel on the
steering wheel. When the
