Detection issues can occur:
When driving on a different
line than the vehicle in front.
A
With vehicles that edge into
your lane. The system can
only detect these vehicles
once they move fully into
your lane.
B
There may be issues with the
detection of vehicles in front
when driving into and coming
out of a bend or curve in the
road.
C
In these cases, the system may brake
late or unexpectedly. The driver
should stay alert and intervene when
necessary. If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This
could cause missed or false vehicle
detections. See an authorized dealer
to have the radar checked for proper
coverage and operation.
System Not Available
Conditions that can cause the system
to deactivate or prevent the system
from activating when requested
include:
•
a blocked sensor
• high brake temperature
• a failure in the system or a related
system.
Blocked Sensor WARNINGS
Do not use the system when
towing a trailer with brake
controls. Aftermarket trailer brakes
will not function properly when the
system is activated because the
brakes are electronically controlled.
Failing to do so may result in loss of
vehicle control, which could result in
serious injury. Do not use tire sizes other than
those recommended because
this can affect the normal operation
of the system. Failing to do so may
result in a loss of vehicle control,
which could result in serious injury. 216

A message displays if something
obstructs the radar signals from the
sensor. The sensor is located behind
a fascia cover near the driver side of
the lower grille. The system cannot
detect a vehicle ahead and will not
function when something obstructs
the radar signals. The following table
lists possible causes and actions for
this message displaying.
Action
Cause
Clean the grille surface in front of the
radar or remove the object causing the obstruction.
The surface of the radar in the grille is
dirty or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that it is no longer obstructed.
The surface of the radar in the grille is
clean but the message remains in the display.
Do not use the system in these condi-tions because it may not detect any vehicles ahead.
Heavy rain or snow is interfering with
the radar signals.
Do not use the system in these condi-tions because it may not detect any vehicles ahead.
Swirling water, or snow or ice on the
surface of the road may interfere with the radar signals.
Wait a short time or switch to normalcruise control.
You are in a desert or remote area with
no other vehicles and no roadside objects.
Due to the nature of radar technology,
it is possible to get a blockage warning
and not be blocked. This can happen,
for example, when driving in sparse
rural or desert environments. A false
blocked condition will either self clear
or clear after a key cycle. Switching to Normal Cruise
Control WARNING
Normal cruise control will not
brake due to slower vehicles.
Always be aware of which mode is
selected and apply the brakes when
necessary. 217

DRIVER ALERT (IF EQUIPPED)
WARNING
The driver alert system is
designed to aid you. It is not
intended to replace your attention and
judgment. You are still responsible to
drive with due care and attention. Note:
The system will store the on/off
setting in the information display menu
through ignition cycles.
Note: If enabled in the menu, the
system will be active at speeds above
40 mph (64 km/h). When below the
activation speed, the information
display will inform the driver that the
system is unavailable.
Note: The system works as long as one
lane marking can be detected by the
camera.
Note: If the camera is blocked or if the
windshield is damaged, the system
may not function.
Note: The system may not be
available in poor weather or other low
visibility conditions.
The system automatically monitors
your driving behavior using various
inputs including the front camera
sensor.
If the system detects that your driving
alertness is reduced below a certain
threshold, the system will alert you
using a chime and a message in the
information display. Using Driver Alert
Switching the system on and off

•
the vehicle is in a dynamic
maneuver
• the road has no or poor lane
markings in the camera
field-of-view
• the camera is obscured or unable
to detect the lane markings due to
environmental conditions (e.g.
significant sun angles or shadows,
snow, heavy rain, fog), traffic
conditions (e.g. following a large
vehicle that is blocking or
shadowing the lane), or vehicle
conditions (e.g. poor headlamp
illumination).
See Troubleshooting for additional
information. Green: Indicates that the system is
available or ready to provide a
warning or intervention, on the
indicated side(s).
Yellow: Indicates that the system is
providing or has just provided a lane
keeping aid intervention.
Red: Indicates that the system is
providing or has just provided a lane
keeping alert warning.
The system can be temporarily
suppressed at any time by the
following:
•
Quick braking
• Fast acceleration
• Using the turn signal indicator
• Evasive steering maneuver
Troubleshooting Why is the feature not available (line markings are gray) when I can see the
lane markings on the road?
Vehicle speed is outside the operational range of the feature
Sun is shining directly into the camera lens
Quick intentional lane change
Staying too close to the lane marking
Driving at high speeds in curves
Previous feature activation happened within the last one second
Ambiguous lane markings (mainly in construction zones)
Rapid transition from light to dark or vice versa
Sudden offset in lane markings
ABS or AdvanceTrac activation

BLIND SPOT MONITOR
Blind Spot Information System
(BLIS®) with Cross Traffic
Alert (If Equipped)
WARNING
To help avoid injuries, NEVER use
the BLIS as a replacement for
using the interior and exterior mirrors
and looking over your shoulder before
changing lanes. BLIS is not a
replacement for careful driving and
only an assist. BLIS aids you in detecting vehicles
that may have entered the blind spot
zone (A). The detection area is on
both sides of the vehicle, extending
rearward from the exterior mirrors to
approximately 10 feet (3 meters)
beyond the bumper. The system alerts
you if certain vehicles enter the blind
spot zone while driving.
Cross traffic alert warns you of
vehicles approaching from the sides
when the transmission is in R
(Reverse). Note:
BLIS is not designed to prevent
contact with other vehicles or objects;
or to detect parked vehicles, people,
animals or infrastructure (fences,
guardrails, trees, etc.). It is designed to
alert the driver to vehicles in the blind
zones.
Note: When a vehicle passes quickly
through the blind zone, typically fewer
than two seconds, the system does not
trigger.
Using the Systems
BLIS turns on when the vehicle is
started and is driven forward above 5
mph (8 km/h); it remains on while the
transmission is in D (Drive) and N
(Neutral). If shifted out of D (Drive) or
N (Neutral), the system enters cross
traffic alert mode. Once shifted back
into D (Drive), BLIS turns back on
when the vehicle is driven above 5
mph (8 km/h).
Note: BLIS does not function in R
(Reverse) or P (Park) or provide any
additional warning when a turn signal
is on.
Note: Cross traffic alert detects
approaching vehicles from up to 45
feet (14 meters) away though coverage
decreases when the sensors are
blocked. Reversing slowly helps
increase the coverage area and
effectiveness.

WARNING
To help avoid personal injury,
NEVER use the cross traffic alert
system as a replacement for using the
interior and exterior mirrors and
looking over your shoulder before
backing out of a parking space. Cross
traffic alert is not a replacement for
careful driving and only an assist. In this first example, the left sensor is
only partially obstructed; zone
coverage is nearly maximized.
