Zone coverage also decreases when parking at shallow angles. Here, the
left sensor is mostly obstructed; zone coverage on that side is severely
limited.
System Lights and Messages
The BLISand CTA systems
illuminate a yellow alert indicator in
the outside mirror on the side of the
vehicle the approaching vehicle is
coming from.
Note:The alert indicator dims when the headlamp switch is not in the
off position and nighttime darkness is detected.
CTA also sounds a series of tones and a message appears in the
information display indicating a vehicle is coming from the right or left.
CTA works with the reverse sensing system which sounds its own series
of tones; see theParking Aidschapter.

System Sensors
WARNING:Just prior to the system recognizing a blocked
condition and alerting the driver, the number of missed objects
will increase. To help avoid injuries, NEVER use the BLISas a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLISis not a replacement for
careful driving and only an assist.
Note:It is possible to get a blockage warning with no blockage present;
this is rare and known as a false blockage warning. A false blocked
condition either self-corrects or clears after a key cycle.
The system uses radar sensors
which are located behind the
bumper fascia on each side of the
vehicle. Do not allow these areas to
become obstructed by mud, snow or
bumper stickers, as this can cause
degraded system performance.
If the system detects a degraded
performance condition,BLIND
SPOT NOT AVAILABLE,or
CROSS TRAFFIC NOT
AVAILABLEappear in the information display and the alert indicator
illuminates in the appropriate mirror(s). The information display warning
can be cleared but the alert indicator remains illuminated.
When the blockage is removed, the system can be reset in two ways: 1)
when at least two objects are detected while driving, or 2) turn the ignition
key from on to off, then back on. If the blockage is still present after the
key cycle, the system senses again that it is blocked after driving in traffic.
Reasons for messages being displayed
The radar surface is
dirty or obstructedClean the fascia area in front of the radar or
remove the obstruction.
The radar surface is
not dirty or obstructedDrive normally in traffic for a few minutes to
allow the radar to detect passing vehicles so it
can clear the blocked state.
Heavy rainfall/snowfall
interferes with the
radar signalsNo action required. The system automatically
resets to an unblocked state once the
rainfall/snowfall rate decreases or stops. Do
not use BLISand/or CTA in these conditions.

System Limitations
The BLISand CTA systems do have their limitations; situations such as
severe weather conditions or debris build-up on the sensor area may
limit vehicle detection.
The following are other situations that may limit the BLIS:
•Certain maneuvering of vehicles entering and exiting the blind zone.
•Vehicles passing through the blind zone at very fast rates.
•When several vehicles forming a convoy pass through the blind zone.
The following are other situations that may limit the CTA system:
•Adjacently parked vehicles or objects obstructing the sensors.
•Approaching vehicles passing at speeds greater than 15 mph
(24 km/h).
•Driving in reverse faster than 3 mph (5 km/h).
•Backing out of an angled parking spot.
False Alerts
Note:When towing a trailer, the sensors detect may detect the trailer,
causing a false alert. You may want to turn the BLISoff if the false
alerts become annoying.
There may be certain instances when either the BLISor CTA systems
illuminate the alert indicator with no vehicle in the coverage zone; this is
known as a false alert. Some amount of false alerts are normal; they are
temporary and self-correct.
System Errors
If either system senses a problem with the left or right sensor, the BLIS
indicator illuminates and remains on andBLIND SPOT SYSTEM
FAULTorCROSS TRAFFIC SYSTEM FAULTappears in the
information display. When problems that may cause the left or right
indicator not to illuminate, only the information display faults appear.
Switching the Systems Off and On
One or both systems can be switched off temporarily by using the
information display control; refer to theInformation Displaychapter.
When the BLISis switched off, the driver does not receive alerts and
the information display shows BLIND SPOT SYS OFF and/or CTA
SYSTEM OFF. The system switches back on whenever the ignition is
switched on.

does not automatically activate the brakes but, if the brake pedal is
pressed, full force braking is applied even if the brake pedal is lightly
pressed.
Using the Collision Warning System
WARNING:The collision warning system’s brake support can
only help reduce the speed at which a collision occurs if the
driver applies the vehicle’s brakes. The brake pedal must be pressed
just like any typical braking situation.
The warning system and chime can be turned on and off separately; the
warning system sensitivity can be adjusted to one of three possible
settings by using the information display control. Refer to the
Information Displayschapter.
Note:If the system cannot be turned off in a vehicle equipped with
MyKey, refer to theMyKeychapter.
Note:If collision warnings are perceived as being too frequent or
disturbing then the warning sensitivity can be reduced, though the
manufacturer recommends using the highest sensitivity setting where
possible. Setting lower sensitivity would lead to fewer and later system
warnings. Refer to theInformation Displayschapter for instructions on
reducing the sensitivity.
Blocked Sensors
If a message regarding a blocked
sensor appears in the information
display, the radar signals from the
sensor have been obstructed. The
sensors are located behind a fascia
cover near the driver side of the
lower grille. When the sensors are
obstructed, a vehicle ahead cannot
be detected and the collision warning system does not function. The
following table lists possible causes and actions for this message being
displayed.

Heavy rain, spray, snow, or fog is
interfering with the radar signalsThe collision warning system is
temporarily disabled. Collision
warning should automatically
reactivate a short time after the
weather conditions improve.

weather conditions improve.
System Limitations
WARNING:The collision warning system’s brake support can
only help reduce the speed at which a collision occurs if the
driver applies the vehicle’s brakes. The brake pedal must be pressed
just like any typical braking situation.
Due to the nature of radar technology, there may be certain instances
where vehicles do not provide a collision warning. These include:
•Stationary vehicles or vehicles moving below 6 mph (10 km/h).
•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lane.
•Severe weather conditions (see blocked sensor section).
•Debris build-up on the grille near the headlamps (see blocked sensor
section).
•Small distance to vehicle ahead.
•Steering wheel and pedal movements are large (very active driving
style).
