Starting and Operating
New Vehicle Break-In
Caution
The vehicle does not need an elaborate
break-in. But it will perform better in the
long run if you follow these guidelines:
.Keep the vehicle speed at 88 km/h
(55 mph) or less for the first 805 km
(500 mi).
.Do not drive at any one constant
speed, fast or slow, for the first
805 km (500 mi). Do not make
full-throttle starts. Avoid downshifting
to brake or slow the vehicle.
.Avoid making hard stops for the first
322 km (200 mi) or so. During this
time the new brake linings are not yet
broken in. Hard stops with new linings
can mean premature wear and earlier
replacement. Follow this breaking-in
guideline every time you get new
brake linings.
(Continued)
Caution (Continued)
.Do not tow a trailer during break-in.
See Trailer Towing 0284 for the
trailer towing capabilities of the
vehicle and more information.
Following break-in, engine speed and load
can be gradually increased.
Ignition Positions
Vehicles equipped with Keyless Access have
pushbutton starting.
The Remote Key must be in the vehicle for
the system to operate. If the pushbutton
start is not working, the vehicle may be
near a strong radio antenna signal causing

left or right or three Safety Alert Seat pulses
occur on the left or right side, 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
TheXbutton located in the customizing
menu is used to turn on or off the Park
Assist.
Front and Rear Park Assist can be set to Off,

the Park Assist button will be disabled. To
turn the Park Assist on again, select On in
vehicle personalization. The On with Towbar
setting allows for Park Assist to work
properly with an attached trailer hitch. Turn

Rear Pedestrian Alert
Under certain conditions, this feature can
provide alerts for a pedestrian within the
system’s range directly behind the vehicle.
This feature only works in R (Reverse) below
12 km/h (8 mph), and detects pedestrians up
to 8 m (26 ft) away during daytime driving.
During nighttime driving, feature
performance is very limited.
Rear Pedestrian Alert Indicator
When a pedestrian is detected within the
system’s range directly behind the vehicle,
this symbol flashes amber on the
infotainment display, along with two beeps
from the rear, or if equipped, two pulses
from both sides of the driver seat. When a
pedestrian is detected close to the vehicle,
the symbol flashes red on the infotainment display, along with seven beeps from the
rear, or if equipped, seven pulses from both
sides of the driver seat.
{Warning
Rear Pedestrian Alert does not
automatically brake the vehicle. It also
does not provide an alert unless it
detects a pedestrian, and it may not
detect all pedestrians if:
.The pedestrian is not directly behind
the vehicle, fully visible to the Rear
Vision Camera (RVC), or standing
upright.
.The pedestrian is part of a group.
.The pedestrian is a child.
.Visibility is poor, including nighttime
conditions, fog, rain, or snow.
.The RVC is blocked by dirt, snow,
or ice.
.The RVC, taillamps, or back-up lamps
are not cleaned or in proper working
condition.
.The vehicle is not in R (Reverse).

pedestrians or other objects. FCA will not
detect another vehicle ahead until it is
completely in the driving lane.
{Warning
FCA does not provide a warning to help
avoid a crash, unless it detects a vehicle.
FCA may not detect a vehicle ahead if
the FCA sensor is blocked by dirt, snow,
or ice, or if the windshield is damaged.
It may also not detect a vehicle on
winding or hilly roads, or in conditions
that can limit visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in proper
condition. Keep the windshield,
headlamps, and FCA sensors clean and in
good repair.
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. Cruise control may be
disengaged when the Collision Alert occurs.
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
[/3to set the FCA
timing to Far, Medium, Near, or on some
vehicles, Off. 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 timing 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
ACC following gap setting (Far, Medium,
or Near).

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.
