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 Blind Spot Information and Cross
Traffic Alert systems illuminate a yellow
alert indicator in the outside mirror on the
side of your vehicle the approaching
vehicle is coming from.
Note:
The alert indicator dims when the
system detects nighttime darkness.
Cross Traffic Alert also sounds a series of
tones and a message appears in the
information display indicating a vehicle is
coming from the right or left. Cross Traffic
Alert works with the reverse sensing
system that sounds its own series of tones.
See Parking Aid (page 202).
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 Blind Spot Information System as
a replacement for using the side and rear
view mirrors or looking over your shoulder
before changing lanes. The Blind Spot
Information System is not a replacement
for careful driving. 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 that are
located behind the tail light lens on each
side of your vehicle. Do not allow mud,
snow or bumper stickers to obstruct these
areas, this can cause degraded system
performance.
If the system detects a degraded
performance condition, a message warning
of a blocked sensor or low visibility appears
in the information display along with a
warning indicator. You can clear the
information display warning but the
warning indicator remains illuminated.
When you remove a blockage, you can
reset the system two ways:
•
While driving, the system detects at
least two objects.
• You cycle the ignition from on to off
and then back on.
If the blockage is still present after the key
cycle and driving in traffic, check again for
a blockage.

Reasons for messages being displayed
Clean the fascia area in
front of the radar or remove the obstruction.
The radar
surface is dirty or
obstructed
Drive normally in traffic for
a few minutes to allow the radar to detect passing
vehicles so it can clear the blocked state.
The radar
surface is
not dirty or
obstructed
No action required. Thesystem automatically
resets to an unblocked
state once the rainfall or
snowfall rate decreases or stops. Do not use BLIS or
Cross Traffic Alert in these conditions.
Heavy rain-
fall or
snowfall
interferes with the radar
signals
System Limitations
The Blind Spot Information and Cross
Traffic Alert 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 Blind Spot Information System:
• 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 Cross Traffic Alert 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: If your vehicle has a factory equipped
tow bar and it is towing a trailer, the sensors
detect the trailer and turn the Blind Spot
Information and Cross Traffic Alert systems
off to avoid false alerts. For non-factory
equipped tow bars, you may want to switch
the Blind Spot Information System off
manually.
There may be certain instances when there
is a false alert by either the Blind Spot
Information or the Cross Traffic Alert
systems that illuminates the alert indicator
with no vehicle in the coverage zone. 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 Blind Spot
Information System telltale illuminates
and a message appears in the information
display. See
Information Messages
(page 120).
All other system faults only display with a
message in the information display.
Switching the Systems Off and On
You can temporarily switch off one or both
systems in the information display. See
General Information
(page 105). When
you switch off the Blind Spot Information
System, you do not receive alerts and the
information display shows a system off
message. The yellow alert indicator in the
outside mirror also flashes twice. The
system turns back on whenever you switch
the ignition on.

FUSE SPECIFICATION CHART
Power Distribution Box
WARNINGS
Always disconnect the battery before
servicing high current fuses.
To reduce risk of electrical shock,
always replace the cover to the
power distribution box before
reconnecting the battery or refilling fluid
reservoirs. The power distribution box is located in
the engine compartment. It has
high-current fuses that protect your
vehicle's main electrical systems from
overloads.
If you disconnect and reconnect the
battery, you will need to reset some
features. See Changing the 12V Battery
(page 308).

CHANGING A FUSE
Fuses WARNING
You must replace a failed fuse with
one that has the specified amperage
rating. If you use a fuse with a higher
amperage rating, you may cause severe
wire damage and may start a fire. A fuse may fail if electrical components in
the vehicle are not properly working. A
broken wire inside the fuse indicates a
failed fuse. Check the appropriate fuses
before replacing any electrical
components.
