Activating/deactivating collision warning system
To turn the warning system and/or chime on or off and set the warning
sensitivity <– –>, refer to Message center in the Instrument Cluster
chapter.
Note: If the system cannot be turned off in a MyKey™ equipped vehicle,
refer to MyKey™ in the Locks and Security chapter for more
information.
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 the Message center in the Instrument Cluster
chapter for instructions on reducing the sensitivity.
