The Blind Spot Information System
illuminates an amber alert indicator in the
outside mirror on the side of your vehicle the
approaching vehicle is coming from. When
the Blind Spot Information System is alerting
on a vehicle and the corresponding turn
signal is ON, the Blind Spot Information
System alert indicator flashes as an
increased warning level.
The alert indicator dims when the system
detects nighttime darkness.
Note: The alert indicator flashes in case of
an alert and the turn signal is set to that side
at the same time.
System Sensor Blockage
WARNING
To help avoid injuries, NEVER use the
Blind Spot Information System as a
replacement for using the interior and
exterior mirrors or looking over your shoulder
before changing lanes. The Blind Spot
Information System is not a replacement for
careful driving.

The system uses radar sensors that are
located behind the bumper fascia on each
side of your vehicle. Any dirt, mud and snow
in front of the sensors and/or driving in heavy
rain can cause system degradation. Also,
other types of obstructions in front of the
sensor can cause system degradation. This
is referred to as a 'blocked' condition.
Note: Do not apply bumper stickers and/or
repair compound to these areas, this can
cause degraded system performance.

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.
