• Highway Driving Assist may
inadvertently operate or turn off
depending on road conditions
(navigation information) and
surroundings.
• Lane Following Assist function may
be temporarily disabled when the
front view camera cannot detect
lanes properly or the hands-off
warning is on.
• You may not hear the warning sound
of Highway Driving Assist if the
surrounding is noisy.
• If the vehicle is driven at high speed
above a certain speed at a curve,
your vehicle may drive to one side or
may depart from the driving lane.
• When you are towing a trailer or
another vehicle, we recommend that
Highway Driving Assist is turned off
due to safety reasons.
• The hands–off warning message
may appear early or late depending
on how the steering wheel is held or
road conditions. Always have your
hands on the steering wheel while
driving.
• For your safety, please read the
owner's manual before using the
Highway Driving Assist.
• Highway Driving Assist will not
operate when the engine is started,
or when the detecting sensors or
navigation is being initialized.Limitations of Highway Driving
Assist
Highway Driving Assist may not operate
normally, or may not operate under the
following circumstances:
• The map information and the
actual road is different because the
navigation is not updated
• The map information and the actual
road is different because of 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 areas such
as a tunnel
• The driver goes off course or the
route to the destination is changed or
canceled by resetting the navigation
• The vehicle enters a service station or
rest area
• Android Auto or Car Play is operating
• The navigation cannot detect the
current vehicle position (ex: elevated
roads including overpass adjacent to
general roads or nearby roads exist in
a parallel way)
Information
For more details on the limitations of
the front view camera, front radar, front
corner radar and rear corner radar, refer
to “Forward Collision-Avoidance Assist
(FCA)” section in chapter 7.

TPMS (Tire Pressure
Monitoring System)
malfunction indicator
The TPMS Malfunction Indicator
will illuminate after it blinks for
approximately one minute when there
is a problem with the Tire Pressure
Monitoring System.
We recommend that you have the
system checked by an authorized
HYUNDAI dealer as soon as possible.
NOTICE
If there is a malfunction with the TPMS,
the Low Tire Pressure Position Indicator
will not be displayed even though the
vehicle has an under-inflated tire.
NOTICE
The TPMS Malfunction Indicator may
illuminate after blinking for one minute
if the vehicle is near electric power
supply cables or radio transmitters
such as police stations, government
and public offices, broadcasting
stations, military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow chains
are used or electronic devices such as
computers, chargers, remote starters,
navigation, etc. This may interfere with
normal operation of the TPMS.
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure and Position indicators will
come on. We recommend that you have
the flat tire repaired by an authorized
HYUNDAI dealer as soon as possible or
replace the flat tire with the spare tire.
NOTICE
It is recommended that you do not
use a puncture-repairing agent not
approved by HYUNDAI dealer or the
equivalent specified for your vehicle to
repair and/or inflate a low pressure tire.
Tire sealant not approved by HYUNDAI
dealer or the equivalent specified for
your vehicle may damage the tire
pressure sensor.
The spare tire (if equipped) does not
come with a tire pressure monitoring
sensor. When the low pressure tire or
the flat tire is replaced with the spare
tire, the Low Tire Pressure Indicator will
remain on. Also, the TPMS Malfunction
Indicator will illuminate after blinking
for one minute if the vehicle is driven
at speed above 15.5 mph (25 km/h) for
approximately 10 minutes.
Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pressure
and reinstalled on the vehicle, the
Low Tire Pressure Indicator and TPMS
Malfunction Indicator will go off within a
few minutes of driving.
If the indicators do not extinguish after
a few minutes, we recommend that you
contact an authorized HYUNDAI dealer.
Each wheel is equipped with a tire
pressure sensor mounted inside the tire
behind the valve stem (except for the
spare tire). You must use TPMS specific
wheels. It is recommended that you
always have your tires serviced by an
authorized HYUNDAI dealer.
