Blind Spot Information System (BLIS)–option
Limitations
In certain situations, the BLIS indicator light(s)
may illuminate even when there are no other
vehicles in the area monitored by the system.
NOTE
If the BLIS indicator lights illuminate occa-
sionally even when there are no other vehi-
cles in the blind area, this does not indicate
a fault in the system.
In the event of a fault,
service required
will be displayed.
The following are several examples of situa-
tions in which the BLIS indicator light(s) may
illuminate even when there are no other vehi-
cles in the area monitored by the system.

Cleaning the BLIS camera lenses

lenses must be kept clean. They can be wiped
clean with a soft cloth or wet sponge.
CAUTION
•
Clean the lenses carefully to avoid
scratching.

The lenses are electrically heated to
help melt ice or snow. If necessary, gen-
tly brush away snow from the lenses.
