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.

jump start your vehicle.
Do not attempt to jump start
your vehicle by push-starting.

What to do in an emergency
Always check the TPMS malfunction
LCD display after replacing one or
more tires or wheels on your vehicle
to ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function proper-
ly.
If any of the below happens, have
the system checked by an author-
ized HYUNDAI dealer.
1. The Low Tire Pressure TPMS
Malfunction Indicator does not
illuminate for 3 seconds when
the Engine Start/Stop button is
placed to the ON position or the
vehicle is in the ready ( )
mode.
2. The TPMS Malfunction Indicator
remains illuminated after blink-
ing for approximately 1 minute.
3. The Low Tire Pressure LCD dis-
play remains illuminated
Low Tire Pressure
Telltale
Low Tire
Pressure LCD
Display with
Position Indicator
When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light.If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle's placard or tire inflation pressure
label located on the driver's side cen-
ter pillar outer panel.
If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure LCD position
indicator will remain on and the
TPMS Malfunction Indicator may
blink for one minute and then remain
illuminated until you have the low
pressure tire repaired and replaced
on the vehicle.
The spare tire is not equipped with
a tire pressure sensor.

If it is hard to loosen the tire hold-
down wing bolt by hand, you can
loosen it easily using the jack handle.
1. Put the jack handle (1) inside of
the tire hold-down wing bolt.
2. Turn the tire hold-down wing bolt
counterclockwise with the jack
handle.
Changing tires
Follow these steps to change your
vehicle's tire:
1. Park on a level, firm surface.
2. Move the shift lever into P (Park),
apply the parking brake, and place
the Engine Start/Stop button in the
OFF position.

button.
4. Remove the wheel lug nut wrench,
jack, jack handle, and spare tire
from the vehicle.
5. Block both the front and rear of the
tire diagonally opposite of the tire
you are changing. A vehicle can slip or roll off of a
jack causing serious injury or
death to you or those nearby.
Take the following safety pre-
cautions:
Never place any portion of
your body under a vehicle that
is supported by a jack.
NEVER attempt to change a
tire in the lane of traffic.
ALWAYS move the vehicle
completely off the road on
level, firm ground away from
traffic before trying to change
a tire. If you cannot find a level,
firm place off the road, call a
towing service for assistance.
Be sure to use the jack pro-
vided with the vehicle.
ALWAYS place the jack on the
designated jacking positions
on the vehicle and NEVER on
the bumpers or any other part
of the vehicle for jacking sup-
port.
(Continued)
(Continued)
Do not start or run the engine
while the vehicle is on the
jack.
Do not allow anyone to remain
in the vehicle while it is on the
jack.
Keep children away from the
road and the vehicle.

What to do in an emergency
The driver must be in the vehi-
cle for steering and braking
operations when the vehicle is
being towed. Passengers other
than the driver must not be in
the vehicle.
CAUTION
Emergency Towing
(if equipped)
If towing is necessary, we recom-
mend you to have it done by an
authorized HYUNDAI dealer or a
commercial tow truck service.If a towing service is not available in
an emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the rear of the vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing should be done only on a
solid ground for a short distance and
at a low speed.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.Always follow these emergency tow-
ing precautions:
Place the Engine Start/Stop button
in the ACC position so the steering
wheel is not locked.
Place the shift lever in N (Neutral).
Release the parking brake.
Depress the brake pedal with more
force than normal since you will
have reduced braking performance.
More steering effort will be required
because the power steering system
will be disabled.
Use a vehicle heavier than your
own to tow your vehicle.
The drivers of both vehicles should
communicate with each other fre-
quently.
Before emergency towing, check
that the hook is not broken or dam-
aged.
Fasten the towing cable or chain
securely to the hook.
Do not jerk the hook. Apply steady
and even force.
