WARNING
• The driver is responsible for
controlling the vehicle for safe
driving.
• Always have your hands on the
steering wheel while driving.
• Highway Driving Assist is a
supplemental function that assists
the driver in driving the vehicle
and is not a complete autonomous
driving system. Always check road
conditions, and if necessary, take
appropriate actions to drive safely.
• Always have your eyes on the road,
and it is the responsibility of the
driver to avoid violating traffic laws.
The vehicle manufacturer is not
responsible for any traffic violation
or accidents caused by the driver.
• Highway Driving Assist may not
be able to recognize all traffic
situations. Highway Driving Assist
may not detect possible collisions
due to limitations of the function.
Always be aware of the limitations
of the function. Obstacles such as
vehicles, motorcycles, bicycles,
pedestrians, or unspecified objects
or structures such as guardrails,
tollgate, etc. that may collide with
the vehicle may not be detected.
• Highway Driving Assist will turn off
automatically under the following
situations:
-Driving on roads that Highway
Driving Assist does not operate,
such as a rest area, intersection,
junction, etc.
-The navigation does not operate
properly such as when the
navigation is being updated or
restarted •
Highway Driving Assist may
inadvertently operate or turn off
depending on road conditions
(navigation information) and
surroundings.

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.

If you have a flat tire while
driving
If a tire goes flat while you are driving:
• Take your foot off the accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake carefully
and pull off the road. Drive off the
road as far as possible and park on
firm, level ground. If you are on a
divided highway, do not park in the
median area between the two traffic
lanes.
• When the vehicle is stopped, press the
hazard warning flasher button, shift
the gear to P (Park), apply the parking
brake, and press the Engine Start/Stop
button to the OFF position.
• Have all passengers get out of the
vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.
• When changing a flat tire, follow the
instructions provided later in this
chapter.
IF THE ENGINE WILL NOT
S TA RT
• Be sure to shift the gear to N (Neutral)
or P (Park). The engine starts only
when the gear is in N (Neutral) or P
(Park).
• Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
See instructions for “Jump Starting”
provided in this chapter.
• Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, we
recommend that you call an authorized
HYUNDAI dealer for assistance.
NOTICE
Push or pull starting the vehicle may
cause the catalytic converter to
overload which can lead to damage to
the emission control system.
