SPEED ALERT
When the Speed Advisor feature is turned on,
HUD displays either the posted or advisory speed as
determined by the information on the map disc in
the navigation system. To turn the Speed Advisor on or
off, see DIC Operation and Displays on page 3-72.
The Speed Advisor can be set to show a speed alert
when the vehicle speed exceeds the speed alert limit
as set in the DIC menu. Depending on the level of
the HUD on the vehicle, your HUD may work like either
of the following:
• The HUD speedometer will turn red when the
vehicle speed exceeds the speed alert limit.
When the vehicle speed is at or below the alert limit
and above the posted speed or advisory speed,
the speedometer turns yellow. If the Speed
Alert setting in the DIC is set to AT LIMIT, the
speedometer will not turn yellow. When the vehicle
speed is at or below the posted speed or advisory
speed, the speedometer remains green.
• The HUD speedometer will turn yellow when the
vehicle speed exceeds the speed alert limit.
When the vehicle speed is at or below the alert
limit, the speedometer remains green.
