If the vehicle is in P (Park), the ignition will
turn off, and Retained Accessory Power
(RAP) will remain active. See Retained
Accessory Power (RAP) 0205.
If the vehicle is in R (Reverse), D (Drive) or
L (Low), the vehicle will shift to P (Park), the
ignition will turn off, and Retained Accessory
Power (RAP) will remain active. See Retained
Accessory Power (RAP) 0205.
If the vehicle is in N (Neutral), the ignition
will return to accessory mode and display
the message SHIFT TO PARK in the Driver
Information Center (DIC). When the vehicle
is shifted into P (Park), the ignition system
will turn off.
The vehicle may have an electric steering
column lock. The lock is activated when the
vehicle is turned off and either front door is
opened. A sound may be heard as the lock
actuates or releases. The steering column
lock may not release with the wheels turned off center. If this happens, the vehicle may
not start. Move the steering wheel from left
to right while attempting to start the
vehicle. If this does not work, the vehicle
needs service.
Do not turn the engine off when the vehicle
is moving. This will cause a loss of power
assist in the brake and steering systems and
disable the airbags.
If the vehicle must be turned off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
After shifting to N (Neutral), firmly apply
the brakes and steer the vehicle to a
safe location.
3. Come to a complete stop and shift to P (Park).
4. Set the parking brake. See Electric

Manual Mode
Electronic Range Select (ERS) Mode
ERS or manual mode allows for the selection
of the range of gear positions. Use this
mode when driving downhill or towing a
trailer to limit the top gear and vehicle
speed. The shift position indicator within the
Driver Information Center (DIC) will display a
number next to the L indicating the highest
available gear under manual mode and the
driving conditions when manual mode was
selected.
To use this feature:1. With the vehicle in D (Drive), press the L (Low) button. 2. Press the plus or minus button on the
center stack to increase or decrease the
gear range available.
When shifting to L (Low), the transmission
will shift to a preset lower gear range. For
this preset range, the highest gear available
is displayed next to the L in the DIC. See
Driver Information Center (DIC) (Base and
Midlevel) 0108 or
Driver Information Center (DIC) (Uplevel and
Denali) 0112. All gears below that number
are available to use. For example, when
4 (Fourth) is shown next to the L, 1 (First)
through 4 (Fourth) gears are shifted
automatically. To shift to 5 (Fifth) gear, press
the + (Plus) button or shift into D (Drive).
L (Low) will prevent shifting to a lower gear
range if the engine speed is too high.
If vehicle speed is not reduced within the
time allowed, the lower gear range shift will
not be completed. Slow the vehicle, then
press the −(Minus) button to the desired
lower gear range.
While using ERS, cruise control can be used.
Drive Systems
All-Wheel Drive
For information on All-Wheel Drive (AWD),
see Driver Mode Control 0218.
Brakes
Electric Brake Boost
Vehicles equipped with electric brake boost
have hydraulic brake circuits that are
electronically controlled when the brake
pedal is applied during normal operation.
The system performs routine tests and turns
off within a few minutes after the vehicle is
turned off. Noise may be heard during this
time. If the brake pedal is pressed during
the tests or when the electric brake boost
system is off, a noticeable change in pedal
force and travel may be felt. This is normal.
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.

Cruise Control
The cruise control lets the vehicle maintain a
speed of about 40 km/h (25 mph) or more
without keeping your foot on the
accelerator. Cruise control does not work at
speeds below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous where
you cannot drive safely at a steady
speed. Do not use cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause

Control
Use the accelerator pedal to increase the
vehicle speed. When you take your foot off
the pedal, the vehicle will slow down to the
previous set cruise speed. While pressing the
accelerator pedal or shortly following the
release to override cruise control, briefly
pressing –SET will result in cruise control set
to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control works on hills
depends upon the vehicle speed, load, and
the steepness of the hills. When going up
steep hills, you might have to step on the
accelerator pedal to maintain the vehicle
speed. When going downhill, you might
have to brake or shift to a lower gear to
keep your speed down. If the brake pedal is
applied, cruise control will disengage. Ending Cruise Control
There are four ways to end cruise control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to N (Neutral).
.To turn off cruise control, press5.
Erasing Speed Memory
The cruise control set speed is erased from
memory if
5is pressed or if the ignition is
turned off.
Adaptive Cruise Control (Camera)
If equipped, Adaptive Cruise Control (ACC)
allows the cruise control set speed and
following gap to be selected. 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 a windshield mounted front
camera sensor.
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.

.Pressing RES+ when there is no longer a
vehicle ahead or the vehicle ahead is
pulling away and the brake is not applied
will cause ACC to resume.
When it is determined that there is no
vehicle ahead or the vehicle ahead is beyond
the selected following gap, then the vehicle
speed will increase to the set speed.
Reducing Speed While ACC Is at a Set Speed
If ACC is already activated, do one of the
following:
.Use the brake to get to the desired lower
speed. Release the brake and press SET–.
The vehicle will now cruise at the lower
speed.
.Press and hold SET– until the desired

APA cannot park in all empty parking spots.
The parking spot must:
.Be sufficiently large to fit the vehicle
comfortably.
.Have an adjacent vehicle, wall, or pillar
for the system to align to.
After completely passing an eligible parking
spot, a beep sounds and a red stop symbol
is displayed in the driver information center. Generally, APA selects the nearest empty
parking spot behind the vehicle, but under
some conditions may select a space that is
further back. Slow down and bring the
vehicle to a complete stop to begin.
Follow the displayed instructions. When
instructed to drive in reverse, shift to
R (Reverse) while holding the brakes. The
steering wheel will vibrate briefly as a
reminder to remove hands from the steering
wheel. After the vibration stops, check your
surroundings and release the brakes to
begin automatic parking. As the vehicle
automatically steers, into the parking spot,
check surroundings and continue to apply
brakes, acceleration and shift gears as
needed. Be prepared to stop to avoid
vehicles, pedestrians, or objects. If the
vehicle exceeds 8 km/h (5 mph), APA is
automatically disengaged.
A progress arrow displays the status of the
parking maneuver. Once automatic parking
is finished and the vehicle is braked to a full
stop, APA will beep and display a message
indicating parking is complete. Secure the
vehicle against rolling away by applying

When your vehicle approaches another
detected vehicle too rapidly, the red FCA
display will flash on the Head-Up Display (if
equipped, and open), or the windshield.
Also, eight rapid high-pitched beeps will
sound from the front , or both sides of the
Safety Alert Seat will pulse five times. When
this Collision Alert occurs, the brake system may prepare for driver braking to occur
more rapidly which can cause a brief, mild
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 Driver Information
Center (DIC). See
Driver Information Center
(DIC) (Base and Midlevel) 0108 or
Driver Information Center (DIC) (Uplevel and
Denali) 0112. 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.

If the LCA displays do not light up when
moving vehicles are in the side blind zone or
are rapidly approaching this zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.
Radio Frequency Information
SeeRadio Frequency Statement 0347.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid crashes due
to unintentional lane departures. This
system uses a camera to detect lane
markings. The LKA system can be ready to
assist at speeds between approximately
60 km/h (37 mph) and 180 km/h (112 mph).
On some vehicles, the system will instead
operate above 50 km/h (31 mph). LKA may
assist by gently turning the steering wheel
if the vehicle approaches a detected lane
marking. It may also provide a Lane
Departure Warning (LDW) alert if the vehicle
crosses a detected lane marking. This system
is not intended to keep the vehicle centered
in the lane. LKA will not assist and alert if
the turn signal is active in the direction of
lane departure, or if it detects that you are
accelerating, braking or actively steering.
LKA can be overridden by turning the
steering wheel. If the system detects you are steering intentionally across a lane
marker, the LDW will not be given. Do not
expect the LDW to occur when you are
intentionally crossing a lane marker.
{Warning
The LKA system does not continuously
steer the vehicle. It may not keep the
vehicle in the lane or give a Lane
Departure Warning (LDW) alert, even if a
lane marking is detected.
The LKA and LDW systems may not:
.Provide an alert or enough steering
assist to avoid a lane departure or
crash.
.Detect lane markings under poor
weather or visibility conditions. This
can occur if the windshield or
headlamps are blocked by dirt, snow,
or ice; if they are not in proper
condition; or if the sun shines directly
into the camera.
.Detect road edges.
.Detect lanes on winding or hilly roads.
(Continued)
Warning (Continued)
If LKA only detects lane markings on one
side of the road, it will only assist or
provide an LDW alert when approaching
the lane on the side where it has
detected a lane marking. Even with LKA
and LDW, you must steer the vehicle.
Always keep your attention on the road
and maintain proper vehicle position
within the lane, or vehicle damage,
injury, or death could occur. Always keep
the windshield, headlamps, and camera
sensors clean and in good repair. Do not
use LKA in bad weather conditions or on
roads with unclear lane markings, such as
construction zones.
{Warning
Using LKA on slippery roads could cause
loss of control of the vehicle and a crash.
Turn the system off.

Mexico-16540740) - 2023 - CRC - 6/16/22
248 Driving and Operating
{Warning
LKA will not alert the driver if a towed
trailer crosses into an adjacent lane of
travel. Serious injury or property damage
may occur if the trailer moves into
another lane. Always monitor the trailer
position 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 console. If equipped, the indicator
light on the button comes on when LKA is
on and turns off when LKA is disabled. On
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
Aamber 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 work at all. An LKA or
LDW unavailable message may display if the
systems are temporarily unavailable. This
message could be due to a blocked camera.
The LKA system does not need service. Clean
the outside of the windshield behind the
rearview mirror.
LKA assistance and/or LDW alerts may occur
due to tar marks, shadows, cracks in the
road, temporary or construction lane
markings, or other road imperfections. This
is normal system operation; the vehicle does
not need service. Turn LKA off if these
conditions continue.
