[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
properly, 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 (for example,
elevated roads including overpass
adjacent to general roads or nearby
roads exist in a parallel way)

Collision-Avoidance Assist (BCA)” section
in chapter 7.
WARNING

[Driving near a vehicle or structure
OHY059017[A] : Structure
Rear Cross-Traffic Safety system
may be limited when driving near
a vehicle or structure, and may not
detect the vehicle approaching from
the left or right. If this occurs, the
system may not warn the driver or
control the brakes when necessary.
Always check your surroundings
while backing up.

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,
move the shift lever into P (Park), and
apply the parking brake, and place
the ignition switch in the LOCK/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.
[Be sure to shift the gear to P (Park).
The vehicle starts only when the gear
is in P (Park).

[ This vehicle does not have a regular
12V battery that needs periodic
replacement. It is lithium ion polymer
type integrated into the HEV high
voltage battery. The vehicle has a
12V battery protection system that
cuts 12V battery from vehicle draw
to prevent full discharge. 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
battery, but you must start vehicle
within 15 seconds of pressing the 12V
Battery Reset switch. After starting
the vehicle (
indicator ON ),
operate the vehicle safely outdoors in
ready mode stopped and/or drive it
for 30 minutes total to charge the 12V
battery fully.

[ Check the fuel level and add fuel if
necessary.

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Shift the gear to P (Park) and set the parking brake
3. Turn off the air conditioner.
4. When the coolant or hot steams gush out of the reservoir, stop the
engine and we recommend that
you call an authorized HYUNDAI
dealer for assistance. If the coolant
does not flow out, leave the engine
compartment opened, while running
the engine. Check the coolant
temperature gauge on the instrument
cluster and turn off the engine to
make sure the coolant temperature is
sufficiently cooled down. 5. Cool down the engine sufficiently
and check the coolant level. When it
is insufficient, check its connection
with the radiator, the heater hose,
and the water pump for any leakage.
When there is no leakage, add the
coolant. However, if the problems
persists, such as the coolant leakages,
the cooling-fan malfunction or the
water pump drive belt damages,
immediately stop the engine, and
have your vehicle checked by an
authorized HYUNDAI dealer.

[ You should mix antifreeze and water in
a proper ratio to make coolant. If the
antifreeze ratio is too high or low, it
may cause overheating due to the lack
of cooling function.
(Refer to the Mix Ratio in “Checking
the coolant level” in chapter 9.)

[ If overheating happens repeatedly,
we recommend that you have
your vehicle to be checked by an
authorized HYUNDAI dealer.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury.
IF THE ENGINE OVERHEATS

Emergency Situations8-18
If you have a tire gauge, check the tire
pressure (see “Tires and Wheels” in
chapter 2 for tire pressure instructions.).
If the pressure is lower or higher than
recommended, drive slowly to the
nearest service station and adjust it to
the recommended pressure. Always
reinstall the valve cap after checking
or adjusting tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy another
and install it as soon as possible. After
changing tires, secure the flat tire and
return the jack and tools to their proper
storage locations. If it is hard to secure
the flat tire, put the flat tire in the
luggage compartment.
NOTICE

[ Check the tire pressure as soon
as possible after installing a spare
tire. Adjust it to the recommended
pressure.

[ Check and tighten the wheel lug
nuts after driving over 30 miles (50
km), after the spare tire is installed.
Recheck the tire wheel lug nuts after
driving over 620 miles (1,000 km)
after the replaced tire is reinstalled.
CAUTION
Your vehicle has metric threads on the
studs and lug nuts. Make certain during
tire changing that the same nuts that
were removed are reinstalled. If you
have to replace your lug nuts make
sure they have metric threads to avoid
damaging the studs and ensure the
wheel is properly secured to the hub.
Consult an authorized HYUNDAI dealer
for assistance.
If any of the equipment such as the jack,
lug nuts, studs, or other equipment is
damaged or in poor condition, do not
attempt to change the tire and call for
assistance.
Use of compact spare tires (if equipped)
Compact spare tires are designed for
emer

gency use only. Drive carefully on
the compact spare tire and always follow
the safety precautions.
WARNING
To prevent compact spare tire failure
and loss of control possibly resulting in
an accident:

[ Use the compact spare tire only in an
emergency.

[ NEVER operate your vehicle over 50
mph (80 km/h).

[ Do not exceed the vehicle’s
maximum load rating or the load
carrying capacity shown on the
sidewall of the compact spare tire.

[ Do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to
avoid failure of the compact spare
tire.

Checking the Engine Oil Level
Engine oil is used for lubrication and
cooling, so it is gradually consumed
during driving the vehicle.
Regularly check and manage the oil level
using the following procedure.
1. Follow all of the oil manufacturer’s precautions.
2. Be sure the vehicle is on the level ground in P (Park) with the parking
brake set. If possible, block the
wheels.
3. Turn the engine on and allow the engine to reach normal operating
temperature.
4. Turn the engine off and wait about 15 minutes (with oil filler cap and dipstick
detached) for the oil to return to the
oil pan.
5. Pull the dipstick out, wipe it clean, and re-insert it fully.
