Traffic Sign Assist - Aston Martin DBX Owner's Handbook Manual

Traffic Sign Assist

Traffic Sign Assist is an aid only. Traffic Sign Assist may not
always be able to correctly display road restrictions. It is the
drivers responsibility to be aware of the traffic signs and
restrictions for the road being driven on. Traffic signs always take
precedent over the display from Traffic Sign Assist.
The Traffic Sign Assist system works with the navigation
system to determine the road speed limit.
The Traffic Sign Assist function shows maximum permitted
speeds for the road in the instrument cluster. The system will also
give indication of any overtaking restrictions and give a warning
if the vehicle is driven down a one way street the wrong way.
When you drive past a traffic sign that applies to the road you are
on, this information will be updated in the instrument cluster.
The Traffic Sign Assist display will update without a visible traffic
sign when you change roads such as joining another road that has
a different speed limit.
If Traffic Sign Assist cannot determine a maximum permitted
speed for the road, no speed limit is shown in the instrument
cluster.
If a traffic sign is passed that gives the end of a road restriction,
such as a speed limit, this information is shown for five seconds.
Applicable traffic regulation will continue to be shown in the
instrument cluster.

Driving
Additional Restrictions
Traffic Sign Assist is capable of detecting traffic signs that have
additional restrictions such as alternative speed limits in wet
conditions.
Additional restrictions will only be displayed if there is a
regulation that must be followed with the restriction, or Traffic
Sign Assist is cannot correctly determine if the restriction is in
effect.
Traffic Sign Settings
Warnings for wrong-way and overtaking restrictions will stay
active when the Traffic sign Assist is set to off.
For settings for Traffic Sign Assist (Refer to 'Assistance', page 10.3)
System Limitations
Traffic Sign Assist may not function correctly in the below
conditions:
• The area around the multi purpose camera is dirty, damaged
or otherwise covered.
• The traffic signs are hard to detect due to insufficient lighting
or obscured by dirt, ice, snow etc.
• Weather conditions such as snow, rain, fog or spray which
can cause low visibility or hide road signs.
• Glare into the multi purpose camera from the sun or other
road users' headlamps.
• The traffic signs are unclear or obscured, such as signs on
construction areas.
• The information in the navigation system is incorrect requires
an update.
