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 M

M (Manual Mode).
2. Press the plus/minus button on the shift lever, to increase or
decrease the gear range
available.
When shifting to M (Manual Mode),
the transmission will shift to a preset
lower gear range. For this preset
range, the highest gear available is
displayed next to the M in the DIC.
See Driver Information Center (DIC)
on page 5-20 for more information.
All gears below that number are
available to use. For example, when
4 (Fourth) is shown next to the M,
1 (First) through 4 (Fourth) gears are
shifted automatically. To shift to
5 (Fifth) gear, press the + (Plus)
button or shift into D (Drive).

9-36 Driving and Operating
Increasing Speed While Using
Cruise Control
If the cruise control system is
already activated:
.Move the thumbwheel up toward
RES/+ and hold it until the
vehicle accelerates to the
desired speed, then release it.
.To increase vehicle speed in
small increments, move the
thumbwheel up toward RES/+
briefly. For each press, the
vehicle goes about 1.6 km/h
(1 mph) faster.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster on
page 5-7. The increment value used
depends on the units displayed. Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
.Move the thumbwheel toward
SET/−
and hold until the desired
lower speed is reached, then
release it.
.To decrease the vehicle speed in
small increments, move the
thumbwheel toward SET/−
briefly. For each press, the
vehicle goes about 1.6 km/h
(1 mph) slower.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster on
page 5-7. The increment value used
depends on the units displayed. Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle slows down to the previously
set cruise control speed. While
pressing the accelerator pedal or
shortly following the release to
override cruise control, briefly
moving the thumbwheel toward
SET/−
will result in cruise 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 maintain the
vehicle speed. When the brakes are
applied, the cruise control is
disengaged.

Driver Assistance
Systems
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
alert and rapidly beeps. FCA also
lights a red 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 40 km/h (25 mph).
{Warning
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
(Continued)
Warning (Continued)
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. FCA does not warn
of pedestrians, animals, signs,
guardrails, bridges, construction
barrels, or other objects. Be ready
to take action and apply the
brakes. For more information, see
Defensive Driving on page 9-3.
FCA can be disabled with the FCA
steering wheel control.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected,

Mexico-7707484) - 2015 - crc - 10/1/14
Driving and Operating 9-39
Consider traffic and weather
conditions when selecting the alert
timing. The range of selectable alert
timing may not be appropriate for all
drivers and driving conditions.
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, cleaning the
outside of the windshield in front of
the rearview mirror may correct the
issue.
Parking Assist
For vehicles with the Rear Parking
Assist (RPA) system, it assists the
driver with parking and avoiding
objects while in R (Reverse). RPA
operates at speeds less than 8 km/h
(5 mph), and the sensors on the rearbumper detect objects up to 2.5 m
(8 ft) behind the vehicle, and at least
20 cm (8 in) off the ground. The
distance objects can be detected
may be less during warmer or humid
weather.
{Warning
The parking assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle
damage, even with parking assist,
always check the area around the
vehicle and check all mirrors
before backing.
How the System Works
RPA comes on automatically when
the shift lever is moved into
R (Reverse). A single beep sounds
to indicate the system is working.
RPA operates only at speeds less
than 8 km/h (5 mph).
A detected obstacle is indicated by
audible beeps. The interval between
the beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is
continuous for five seconds.
Turning the System On and Off
The RPA system can be turned on
and off using the infotainment
system controls. See
Vehicle
Personalization on page 5-31 for
more information.
The On with Tow Bar Attached
setting allows for the parking assist
to work properly with a small item
attached to the trailer hitch.
When the system is off, PARK
ASSIST OFF displays on the Driver
Information Center (DIC). The
message disappears after a short
period of time.
RPA defaults to the on setting each
time the vehicle is started.

of the vehicle. This is normal system
operation; the vehicle does not need
service.
SBZA may not always alert the
driver to vehicles in the side blind
zone, especially in wet conditions.
The system does not need to be
serviced. The system may light up
due to guardrails, signs, trees,
shrubs, and other non-moving
objects. This is normal system
operation; the vehicle does not need
service.
SBZA may not operate when the
SBZA sensors in the left or right
corners of the rear bumper are
covered with mud, dirt, snow, ice,
or slush, or in heavy rainstorms. For
cleaning instructions, see "Washing
the Vehicle" underExterior Care on
page 10-73. If the DIC still displays
the system unavailable message
after cleaning both sides of the
vehicle toward the rear corners of
the vehicle, see your dealer. If the SBZA displays do not light up
when vehicles are in the blind zone
and the system is clean, the system
may need service. Take the vehicle
to your dealer.
When SBZA is disabled for any
reason other than the driver turning
it off, the Side Blind Zone Alert On
option will not be available on the
personalization menu.
Radio Frequency Information
See
Radio Frequency Statement on
page 13-12.
Rear Vision
Camera (RVC)
If equipped, the RVC can assist the
driver when backing up by
displaying a view of the area behind
the vehicle.
{Warning
The RVC system does not display
children, pedestrians, bicyclists,
crossing traffic, animals, or any
other object located outside the
camera's field of view, below the
bumper, or under the vehicle.
Perceived distances may be
different from actual distances.
Do not back the vehicle using
only the RVC screen. Failure to
use proper care before backing
may result in injury, death,
or vehicle damage. Always check
behind and around the vehicle
before backing.
An image appears on the
infotainment screen when the
vehicle is shifted into R (Reverse).
The infotainment screen goes to the
previous screen after approximately
10 seconds once the vehicle is
shifted out of R (Reverse).
