If the system detects a degraded
performance condition, a message warning
of a blocked sensor will appear in the
information display. Also the BLIS alert
indicators will remain ON and BLIS will no
longer provide any vehicle warnings. You
can clear the information display warning
but the alert indicators will remain
illuminated.
A "blocked" condition can be cleared in
two ways:
•
After the blockage in front of the
sensors is removed or the
rainfall/snowfall rate decreases or
stops, drive for a few minutes in traffic
to allow the sensors to detect passing
vehicles.
•
By cycling the ignition from ON to OFF
and then back ON.
Note:
If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Blind Spot
Information System off. If your vehicle has
a tow bar but no factory equipped trailer
tow module, it is recommended to turn the
Blind Spot Information System off
manually. Operating the Blind Spot
Information System with a trailer attached
will cause poor system performance.
System Errors
If the system senses a problem with the
left or right sensor, the telltale will
illuminate and a message will appear in
the information display. See
Information
Messages
(page 124).
Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the information
display. See
General Information
(page
108). When the Blind Spot Information
System switches off, you will not receive
alerts and the information display shows
a system off message. The telltale in the
cluster also illuminates. When you switch
the Blind Spot Information System on or
off, the alert indicators flash twice.
Note:
The Blind Spot Information System
remembers the last selected on or off
setting.
You can also have the Blind Spot
Information System switched off
permanently at an authorized dealer. Once
switched off permanently, the system can
only be switched back on at an authorized
dealer.
