Collision alert
When your vehicle approaches
another vehicle too rapidly, the red
forward collision alert display will flash
and sound several beeps. When this
occurs, the brake system prepares for
driver braking to occur more rapidly.
Continue to apply the brake pedal as
the driving situation dictates.
Tailgating alert
The red forward collision alert display
will remain illuminated continuously if
the vehicle ahead remains much too
close.
Selecting the alert sensitivity
The alert sensitivity can be set to
near, medium or far.
Press COLLISION ALERT F to show
the current setting on the Driver
Information Centre (DIC). Press
again to change the alert sensitivity.
The chosen setting will remain until it
is changed and will affect both the
collision alert and the tailgating alert
features. The timing of both alerts will
vary based on vehicle speed. The
faster the vehicle speed, the further
away the alert will occur.
Consider traffic and weather
conditions when selecting the alert
sensitivity. The range of selectable
Driving and operating
alert sensitivity may not be
appropriate for all drivers and driving
conditions.
Unnecessary alerts
The forward collision alert may
sometimes set unnecessary alerts to
turning vehicles, vehicles in other
lanes, objects that are not vehicles, or
shadows. These alerts are normal
and the vehicle does not need a
service.
Other messages
There are messages that may appear
on the Driver Information Centre
(DIC) in the instrument cluster to
provide information about the forward
collision alert.
Cleaning the system
If the forward collision alert system
does not seem to operate properly,
clean the outside of the windscreen
area in front of the camera sensor
before considering taking the vehicle
to a workshop.
