Driver Assistance
Systems
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 camera(s) do not display
children, pedestrians, bicyclists,
crossing traffic, animals, or any
other object outside of the
cameras’field of view, below the
bumper, or under the vehicle.
Shown distances may be different
from actual distances. Do not
drive or park the vehicle using
only these camera(s). Always
check behind and around the
vehicle before driving. Failure to
use proper care may result in
injury, death, or vehicle damage. 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).
To see the previous screen sooner,
do one of the following:
.
Press a hard key on the
navigation system.
. Shift into P (Park).
Press MENU to adjust the display
brightness while viewing the rear
camera display.
Symbols and Guidelines
The RVC system may have a
feature that lets the driver view
parking assist symbols on the
infotainment screen while using the
RVC. The Rear Parking Assist
(RPA) system must not be disabled
to use the caution symbols. The
error message Rear Parking Assist
Symbols Unavailable may display if
RPA has been disabled and the
symbols have been turned on. See
Parking Assist 0184. Rear Cross Traffic Alert (RCTA)
On vehicles with RCTA, a triangle
with an arrow may display on the
RVC screen to warn of traffic
coming from either direction. This
system detects objects coming from
up to 20 m (65 ft) from the left or
right side, behind the vehicle. When
an object is detected, three beeps
sound from the left or right side,
depending on the direction of the
detected vehicle.
The parking assist and RCTA
symbols appear and may cover an
object when viewing the
infotainment screen when an object
is detected by the RPA or RCTA
system.
The RVC system may also have a
guideline overlay that can help the
driver align the vehicle when
backing into a parking spot.
To turn the symbols or guidelines on
or off:
1. Shift into P (Park).
2. Press the CONFIG button.
3. Select Display Settings.

184 Driving and Operating
When the System Does Not
Seem To Work Properly
The RVC system may not work
properly or display a clear image if:
.It is dark.
. The sun or the beam of
headlamps is shining directly
into the camera lens.
. Ice, snow, mud, or anything else
builds up on the camera lens.
Clean the lens, rinse it with
water, and wipe it with a soft
cloth.
. The back of the vehicle is in an
accident. The position and
mounting angle of the camera
can change or the camera can
be affected. Be sure to have the
camera and its position and
mounting angle checked at your
dealer.
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 rear
bumper 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 0125 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.
Turn RPA off when towing a trailer.

When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST :If
this message occurs, check the
following conditions:
. The sensors are not clean. Keep
the vehicle's rear bumper free of
mud, dirt, snow, ice, and slush.
For cleaning instructions, see
Exterior Care 0269.
. The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system. PARK ASSIST OFF :
If the RPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
. The driver has disabled the
system.
. A trailer was attached to the
vehicle, or an object was
hanging out of the liftgate during
the last drive cycle. Once the
object is removed, RPA will
return to normal operation.
. A tow bar is attached to the
vehicle.
. The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
. Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
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,
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,

Driving Characteristics
and Towing Tips
Driving with a Trailer
When towing a trailer:
.
Become familiar with the state
and local laws that apply
specifically to trailer towing. .
Do not tow a trailer during the
first 800 km (500 miles), to
prevent damage to the engine,
axle or other parts.
. Then, during the first 800 km
(500 miles) trailer towing, do not
drive over 80 km/h (50 mph) and
do not make starts at full throttle.
. The vehicle can tow in D (Drive).
Use a lower gear if the
transmission shifts too often.
. Do not use the Fuel Economy
Mode when towing.
. Turn off Park Assist when
towing.
{Warning
When towing a trailer, exhaust
gases may collect at the rear of
the vehicle and enter if the
liftgate, trunk/hatch, or rear-most
window is open.
When towing a trailer:
(Continued)
Warning (Continued)
.Do not drive with the
liftgate, trunk/hatch,
or rear-most window open.
. Fully open the air outlets on
or under the instrument
panel.
. Also adjust the climate
control system to a setting
that brings in only outside

monoxide, see Engine
Exhaust 0171.
Towing a trailer requires a certain
amount of experience. The
combination you are driving is
longer and not as responsive as the
vehicle itself. Get acquainted with
the handling and braking of the rig
before setting out for the open road.
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirrors. If the trailer has

Vehicle Care 219
Engine Overheating
The vehicle has an indicator to warn
of engine overheating. There is an
engine coolant temperature warning
light on the vehicle's instrument
panel. SeeEngine Coolant
Temperature Gauge 0104.
The decision may be made not to lift
the hood when this warning
appears, but instead get service
help right away. See Roadside
Assistance Program 0299.
If the decision to lift the hood is
made, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fan(s) are running. If the
engine is overheating, the fan(s)
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
If Steam is Coming from the
Engine Compartment
{Warning
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.
Climbs a long hill on a hot day.
. Stops after high-speed driving.
. Idles for long periods in traffic.
. Tows a trailer.
If the overheat warning is displayed
with no sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the
highest fan speed. Open the
windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or
N (Neutral) and let the
engine idle.
If the temperature overheat gauge is
no longer in the overheat zone or an
overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
