Hill Descent
Control (HDC)
If equipped, HDC can be used when
driving downhill. It sets and
maintains vehicle speed while
descending a very steep incline in a
forward or reverse gear.
The HDC switch is on the center
console.
Press
5to enable or disable HDC.
Vehicle speed must be below
50 km/h (31 mph).
A blinking HDC light indicates the
system is actively applying the
brakes to maintain vehicle speed.
HDC can maintain vehicle speeds
between 3–22 km/h (2–14 mph) on
an incline greater than or equal to a
10% grade.
When HDC is activated, the initial
HDC speed is set to the current
driving speed. It can be increased or
decreased by pressing the RES+ or
SET– steering wheel controls or by
applying the accelerator or brake
pedal. This adjusted speed
becomes the new set speed.
HDC will remain enabled between
22–60 km/h (14–37 mph); however
vehicle speed cannot be set or
maintained in this range. It will
automatically disable if the vehicle
speed is above 80 km/h (50 mph) or

above 60 km/h (37 mph) for at least
30 seconds. Press
5again to
re-enable HDC.
Driver Mode Control
If equipped, the Driver Mode Control
has the following Modes: Tour
(FWD), Sport, All-Wheel Drive
(AWD), Snow/Ice, Tow/Haul, and
Off-Road. Rotate the Driver Mode
Control knob on the center console
to make a mode selection. Continue
turning the knob through the
available modes. The selected
mode’s icon will light up on the knob
and there may be additional
messages in the Driver Information
Center (DIC) and indicators in the
instrument cluster.
If the vehicle is in Tour (FWD) or
AWD, it will stay in that mode
through future ignition cycles. If the
vehicle is in any other mode, it will
revert back to Tour (FWD) when the
vehicle is restarted.
Driver Mode Control Knob (AWD)
Driver Mode Control Knob (FWD)
5orqTour (FWD) : Vehicle is in
Tour (FWD) Mode. Use this mode
during normal driving conditions.
See Driving for Better Fuel
Economy 0174. Tour (FWD) Mode
operates in Front-Wheel Drive to
improve fuel economy.
8Sport : Sport Mode improves
vehicle handling and acceleration
on dry pavement. When active,
Sport Mode modifies steering
efforts, transmission shifting, AWD
torque, and suspension tuning
(when properly equipped). For AWD
vehicles, choosing Sport Mode also
engages AWD Mode.
The Performance Algorithm Liftfoot
(PAL) feature is enabled in Sport
Mode. PAL allows the transmission
to hold the current gear after a quick
release of a heavily applied
accelerator pedal. This provides
greater engine braking and
enhanced vehicle control.
When PAL is activated, there may
be an additional green gear symbol
which appears in the instrument
cluster display. See Gear Shifting
Light 0131.

Driving and Operating 231
The instrument cluster may have a
Park Assist display with bars that
show“distance to object” and object
location information for RPA. As the
object gets closer, more bars light
up and the bars change color from
yellow to amber to red.
When an object is first detected in
the rear, one beep will be heard
from the rear, or both sides of the
Safety Alert Seat will pulse two
times. When an object is very close
(<0.6m (2 ft) in the vehicle rear,
or <0.3m (1 ft) in the vehicle front),
five beeps will sound from the rear,
or both sides of the Safety Alert
Seat will pulse five times. Rear Cross Traffic Alert (RCTA)
If equipped, RCTA shows a red
warning triangle with a left or right
pointing arrow on the infotainment
display to warn of traffic coming
from the left or right. This system
detects objects coming from up to
20 m (65 ft) from the left or right side
of the vehicle. When an object is
detected, three beeps sound from
the left or right, depending on the
direction of the detected vehicle.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out
from the back of the vehicle do not
move further back when a trailer is
towed.
Turning the Features On or Off
To turn RPA on or off, pressXon
the center console. The indicator
light next to the button comes on
when the features are on and turns
off when the features have been
disabled. RCTA and Rear Park Assist
symbols can be turned on or off
through vehicle personalization. See
“Collision/Detection Systems”
under
Vehicle Personalization 0146.
Turn off RPA when towing a trailer.
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
If equipped, 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

Mexico-13687875) - 2020 - CRC - 10/28/19
Driving and Operating 241
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 while towing a trailer
or on slippery roads could cause
loss of control of the vehicle and
a crash. Turn the system off.
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 that
a lane marking has been crossed.
To turn LKA on and off, press
A
on the center console. If equipped,
the indicator light on the button
comes on when LKA is on and turns
off when LKA is disabled.
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 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.
