Driving and Operating 225
If the Park Assist System does not activate
due to a temporary condition, a system off
message is shown on the display. This can
occur under the following conditions:
.The driver has disabled the system.
.An object is currently blocking the rear
sensors (for example, bike rack, tailgate,
trailer hitch, etc.). Once the object is
removed, Park Assist will return to normal
operation.
.The bumper is damaged. Take the vehicle
to your dealer for repairs.
.Other conditions, such as vibrations from
a jackhammer or the compression of air
brakes on a very large truck, are affecting
system performance.
Automatic Parking Assist (APA)
Enhanced Automatic Parking Assist (APA)
If equipped, under certain conditions
Enhanced Automatic Parking Assist (APA) can
use sensors based on sonar technology
along the vehicle’s front, rear and sides to
detect a parking spot and automatically park
the vehicle. The vehicle will automatically
maneuver into a detected spot moving at or
near idle speed. It does this by
automatically steering, braking, accelerating,and gear shifting. The driver must always be
prepared to apply braking if necessary. A
display and beeps help to guide the parking
maneuvers.
{Warning
APA may not always detect objects in the
parking space, objects that are not rigid
(e.g. shrubs and chain-link fences), objects
below the bumper, objects high off the
ground (e.g. flatbed trucks), hanging
objects, objects below ground level (e.g.
large potholes), or moving objects (e.g.
pedestrians, cyclists, vehicles). Always
verify that the parking space is
appropriate for parking a vehicle. APA
may not respond to changes in the
parking space, such as movement of an
adjacent vehicle, or a person or object
entering the parking space. APA does not
detect or avoid traffic that is behind or
alongside of the vehicle. Always be
prepared to stop the vehicle during the
parking maneuver.
How to Activate Automatic Parking
To activate APA, press the soft-touch button
or hard switch
Ofor the system to begin
searching for a parking space while driving
forward at no greater than
30 km/h (18 mph). By default, APA searches
for parallel parking spaces to the right of
the vehicle up to the sensors’ range of 1.5 m
(5 ft). To search for a parking space to the
left, turn on the left turn signal or,
if available, change the side selection in the
infotainment display. To switch the parking
mode between parallel and perpendicular
press and hold
Owhile searching for a
valid parking spot or, if available, change the
parking mode in the infotainment display.
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.

226 Driving and Operating
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. Release the brakes slowly when the
vibration stops to begin automatic parking.
As the vehicle automatically steers, brakes,
accelerates, and shifts gears into the parking
spot, check surroundings. Be prepared to
stop to avoid vehicles, pedestrians,
or objects.A progress arrow displays the status of the
parking maneuver. Once automatic parking
is finished and the vehicle has come to a full
stop, a message will be displayed. Press and
hold the brakes, and APA will beep and
display a message indicating parking is
complete. Shift the vehicle to P (Park) and
apply the parking brake.
How to Activate Automatic Parallel Spot
Unparking Assist
To activate parallel spot unparking assist,
press the soft-touch button or hard switch
Oafter turning on the vehicle while
leaving it in P (Park) and the parking brake
is off. If the system is able to determine a
path out of the parking spot, a screen will
be displayed for unparking options. Similar
to automatic parking, follow the displayed
instructions and check surroundings as the
vehicle unparks. Once automatic unparking is finished and
the vehicle has come to a full stop, FINAL
POSITION - PRESS BRAKES message will be
displayed. Press and hold the brakes, and
APA will beep and display a TAKE CONTROL
message. The vehicle is now positioned such
that the path to exit the parking spot is free
of obstructions. Shift into D (Drive) to start
driving away.
How to Cancel Automatic Parking or
Automatic Unparking
To cancel automatic parking or automatic
unparking at any time, press
Oor "X" on
the infotainment display and be prepared to
resume control of the vehicle. APA holds the
vehicle until the parking brake or brake is
applied, or the vehicle is shifted into
P (Park). To start driving away, press the
brakes and shift into D (Drive).

Without Head-Up Display
When your vehicle approaches another
detected vehicle too rapidly, the red FCA
display will flash on 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) 0106. The minimum following time is
0.5 seconds away.
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.
.Clean the headlamps.
Automatic Emergency
Braking (AEB)
The AEB system may help avoid or reduce
the harm caused by front-end crashes. AEB
also includes Intelligent Brake Assist (IBA).

Driving and Operating 237
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 between 60 km/h (37 mph) and
180 km/h (112 mph). It 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. LKA can be overridden by
turning the steering wheel. 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.
If the system detects that you are steering
intentionally across a lane marker, the LDW
may not be given. Do not expect the LDW
to occur when you are intentionally crossing
the 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.
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. (Continued)
Warning (Continued)
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.
{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.

238 Driving and Operating
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 sytem does not provide a 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.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
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.

that extend out from the back of the vehicle
do not move further back when a trailer is
towed.
{Warning
To prevent serious injury or death from
carbon monoxide (CO), when towing a
trailer:
.Do not drive with the liftgate, trunk/
hatch, or rear-most window open.
.Fully open the air outlets on or under
the instrument panel.
.Adjust the climate control system to a
setting that brings in only outside air.
See“Climate Control Systems” in the
Index.
For more information about carbon
monoxide, see Engine Exhaust 0197.
Towing a trailer requires experience. The
combination of the vehicle and trailer is
longer and not as responsive as the vehicle
itself. Become familiar to the handling and
braking by driving on a level road surface
before driving on public roads.
The trailer structure, the tires, and the
brakes must be all be rated to carry the
intended cargo. Inadequate trailer equipment can cause the combination to
operate in an unexpected or unsafe manner.
Before driving, inspect all trailer hitch parts
and attachments, safety chains, electrical
connectors, lamps, tires, and mirrors. See
Towing Equipment
0247. If the trailer has
electric brakes, start the combination
moving and then manually apply the trailer
brake controller to check that the trailer
brakes work. During the trip, occasionally
check that the cargo and trailer are secure
and that the lamps and any trailer brakes
are working.Towing with a Stability Control System
When towing, the stability control system
might be heard. The system reacts to
vehicle movement caused by the trailer,
which mainly occurs during cornering. This is
normal when towing heavier trailers.
Following Distance
Stay at least twice as far behind the vehicle
ahead as you would when driving without a
trailer. This can help to avoid heavy braking
and sudden turns.
Passing
More passing distance is needed when
towing a trailer. The combination of the
vehicle and trailer will not accelerate as
quickly and is much longer than the vehicle
alone. It is necessary to go much farther
beyond the passed vehicle before returning
to the lane. Pass on level roadways. Avoid
passing on hills if possible.
Backing Up
Hold the bottom of the steering wheel with
one hand. To move the trailer to the left,
move that hand to the left. To move the
trailer to the right, move that hand to the
right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Caution
Turn more slowly and make wider arcs
when towing a trailer to prevent damage
to your vehicle. Making very sharp turns
could cause the trailer to contact the
vehicle.

Vehicle Care 257
Engine oil system flushes are not
recommended and could cause engine
damage not covered by the vehicle
warranty.
What to Do with Used Oil
Used engine oil contains certain elements
that can be unhealthy for your skin and
could even cause cancer. Do not let used oil
stay on your skin for very long. Clean your
skin and nails with soap and water, or a
good hand cleaner. Wash or properly
dispose of clothing or rags containing used
engine oil. See the 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 offactors which include engine revolutions,
engine temperature, and miles driven. Based
on driving conditions, the mileage at which
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 may
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 controls on the right side of the steering wheel, display remaining
OIL LIFE on the DIC. See Driver
Information Center (DIC) 0106. When
remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear
on the display.
2. Press the thumbwheel while the Oil Life display is active. When the confirmation
message displays, select YES. The oil life
will change to 100%.
Be careful not to reset the oil life display
accidentally at any time other than after
the oil is changed. It cannot be reset
accurately until the next oil change.
The system is reset when the CHANGE
ENGINE OIL SOON message is off.
If the CHANGE ENGINE OIL SOON message
comes back on when the vehicle is started,
the engine oil life system has not been
reset. Repeat the procedure.
