Collision Alert
With Head-Up Display
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).

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
can be ready to assist at
speeds between 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 oractively steering. LKA can be
overridden by turning the
steering wheel. If the system
detects 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 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
(Continued)
Warning (Continued)
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. 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, (Continued)

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(Continued)
Warning (Continued)
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 stack.
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
A
amber 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.

attachments, safety chains,
electrical connectors, lamps,
tires, and mirrors. See Towing
Equipment0322. 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.
Make wider turns than normal
when towing, so the trailer will
not go over soft shoulders,
over curbs, or strike road
signs, trees, or other objects.
Always signal turns well in
advance. Do not steer or brake
suddenly.
Driving on Grades
Reduce speed and shift to a
lower gear before starting
down a long or steep downhill
grade. If the transmission is
not shifted down, the brakes
may overheat and result in
reduced braking efficiency.

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 of factors 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 OILSOON 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)
0136. When remaining oil
life is low, the CHANGE
ENGINE OIL SOON
message will appear on the
display.
2. Press
Von the DIC
controls and hold down for
a few seconds to clear the
CHANGE ENGINE OIL
SOON message and reset
the oil life at 100%.
Be careful not to reset the
oil life display accidentally
at any time other than
after the oil is changed.
