Highway Driving Assist system
is not a substitute for safe driv-
ing practices, but a conven-
ience function. It is the respon-
sibility of the driver to always
be aware of the surroundings
and drive safely.
Highway Driving Assist sys-
tem relies entirely on the road
information provided by the
navigation system. It is the
responsibility of the driver to
follow traffic laws and avoid
accidents.
Turn off the Highway driving
assist system when the vehi-
cle is being towed.
For your safety, please read
the owner's manual before
using the system.

keeping a straight line. Move cau-
tiously off the road to a safe place.

What to do in an emergency
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 immedi-
ately 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,
move the shift lever into P (Park),
and apply the parking brake, and
place the Engine Start/Stop button
in 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.
Hybrid vehicle
Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
This vehicle does not have a regu-
lar 12V battery that needs periodic
replacement. It is lithium ion poly-
mer type integrated into the HEV
high voltage battery. The vehicle
has a 12V battery protection sys-
tem that cuts 12V battery from
vehicle draw to prevent full dis-
charge. If vehicle will not start, first
try pressing the 12V Battery Reset
switch (left side of the steering
wheel near the fuel door open
switch) to reconnect the 12V bat-
tery, but you must start vehicle
within 15 seconds of pressing the
12V Battery Reset switch. After
starting vehicle, operate the vehi-
cle safely outdoors in ready mode
stopped and/or drive it for 30 min-
utes total to charge the 12V battery
fully.Push or pull starting the vehicle
may cause the catalytic converter
to overload which can lead to
damage to the emission control
system.
Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, have
your vehicle checked by an author-
ized HYUNDAI dealer.
