Hyundai Tucson: Highway Driving Assist (HDA) / Highway Driving Assist
Malfunction and Limitations
Highway Driving Assist malfunction
When Highway Driving Assist is not
working properly, the "Check Highway
Driving Assist (HDA) system" warning
message may appear, and the
warning light may illuminate on the
instrument cluster. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
WARNING
Always check road conditions, and if
necessary, take appropriate actions to
drive safely. Highway Driving Assist is
a supplemental function only and it is
not a self driving or autonomous driving
system.
To prevent serious injury or death:
- Always have your hands on the
steering wheel while driving.
- Always have your eyes on the road and
pay attention. It is your responsibility
to avoid violating traffic laws.
- Highway Driving Assist may not be
able to recognize all traffic situations
and may not detect possible collision
hazards. Obstacles such as vehicles,
motorcycles, bicycles, pedestrians, or
unspecified objects or structures (e.g.
guardrails and tollbooth) may not be
detected.
- Highway Driving Assist turns off
automatically under the following
situations:
- You are driving on roads that
Highway Driving Assist does
not operate, such as rest area,
intersection, junction, etc.
- The navigation does not operate
properly such as when the
navigation system is updating or
restarting.
- Highway Driving Assist may
inadvertently operate or turn off
depending on the road conditions
(based on the navigation system
information) and surroundings.
- Lane Following Assist may be
temporarily disabled when the front
view camera cannot detect lanes
properly or the hands-off warning is
on.
- The hands–off warning message may
appear early or late depending on
how the steering wheel is held or road
conditions.
- You may not hear the audible warning
of Highway Driving Assist if the
surrounding environment is too noisy.
- When your vehicle is driven at high
speeds through a curve, your vehicle
may depart from your driving lane if
you do not maintain control.
- When you are towing a trailer or
another vehicle, turn off Highway
Driving Assist.
- Highway Driving Assist may not
operate right after the engine is
started or when the sensors or
navigation system is initialized.
Limitations of Highway Driving
Assist
Highway Driving Assist may not operate
normally or may not operate if:
- The map information differs from
the actual road conditions because
the navigation system has not been
updated, or there is a real-time GPS
data or map information error.
- The infotainment system is overloaded
by simultaneously performing
functions such as route search, video
playback, voice recognition, etc.
- GPS signals are blocked in an area
such as tunnel.
- You depart from the navigation route
or the route to the destination is
changed or canceled.
- Your vehicle enters a service station or
rest area.
- Android Auto or Car Play is operating.
- The navigation system cannot detect
the current vehicle position (e.g.
elevated roads including overpass
adjacent to general roads or nearby
roads exist in a parallel way).
- A trailer or hitch mounted carrier is
connected to your vehicle.
