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.

To prevent SERIOUS INJURY or
DEATH to you or bystanders,
always follow these precautions
when working near or handling
the battery:
Always read and follow
instructions carefully
when handling a battery.
Wear eye protection
designed to protect the
eyes from acid splashes.
Keep all flames, sparks,
or smoking materials
away from the battery.
Hydrogen is always
present in battery cells,
is highly combustible,
and may explode if ignit-
ed.
Keep batteries out of
reach of children.
(Continued)
WARNING (Continued)
Batteries contain sulfu-
ric acid which is highly
corrosive. Do not allow
acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical attention immediately.
When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak. Lift with a battery
carrier or with your hands on
opposite corners.
Do not attempt to jump start
your vehicle if your battery is
frozen.

What to do in an emergency
If your engine coolant 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. Turn ON the hazard warning flash-
er, pull off the road and stop as
soon as it is safe to do so.
2. Place the shift lever in P (Park)
and set the parking brake.
3. Make sure that there is no hot
steam gushing out of the engine
compartment. When it is safe to
do so, open the engine compart-
ment, and check the water-pump
connector. When the water-pump
connector is disconnected, stop
the engine, re-connect the water-
pump connector, and then re-start
the engine.
4. Set the temperature and the air
flow to the maximum, and turn ON
the air conditioner.5. When the Service warning light
( ) illuminates on the instru-
ment cluster, immediately stop the
engine, and contact an authorized
HYUNDAI dealer. When the
engine warning light ( ) illumi-
nates, or when the coolant or hot
steams gush out of the engine
compartment, leave the engine
compartment opened, while run-
ning the engine. This is to ventilate
the engine compartment and to
cool down the engine.
6. Check the coolant temperature
gauge on the instrument cluster to
make sure the coolant temperature
is sufficiently cooled down. Check
the coolant level. When it is insuffi-
cient, 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 illumination of
the warning lights, leakages, or the
cooling-fan malfunction, which may
overheat the engine, immediately
stop the engine, and have your
vehicle checked by an authorized
HYUNDAI dealer.

7. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
8. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
Your vehicle is
equipped with a pres-
surized coolant
reserve tank. NEVER
remove the coolant
reserve tank cap or the radiator
drain plug while the engine and
radiator are HOT. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the coolant reserve tank
cap. Wrap a towel or thick rag
around it, and turn it counter-
clockwise slowly to release
some of the pressure from the
system. Step back while the
pressure is released.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.

Tire Pressure Monitoring
System
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly underinflated tire causes the
tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver's responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subse-
quent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the
TPMS to continue to function proper-
ly. Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
may cause loss of vehicle con-
trol resulting in an accident.
WARNING

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.

TPMS 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.
Have the system checked by an
authorized HYUNDAI dealer as soon
as possible.
If there is a malfunction with the
TPMS, the individual tire pres-
sures in the cluster LCD display
will not be available. Have the sys-
tem checked by an authorized
HYUNDAI dealer as soon as possi-
ble.
NOTICE
During winter or cold weather,
the TPMS indicator may illumi-
nate if the tire pressures were
set when the outside tempera-
ture was warm. As the outside
air becomes colder, the pres-
sure in the tires will decrease.
Similarly, if the outside air
becomes warmer, the pressure
in the tires will increase. As you
drive your vehicle, the tempera-
ture of the tires will heat up,
therefore the tire pressures will
increase. Check and adjust your
tire pressures regularly before
driving to make sure your vehi-
cle is operating at the correct
pressures as designed.
CAUTION
Low pressure damage
Significantly low tire pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased braking
distances.
Continued driving on low pres-
sure tires can cause the tires to
overheat and fail.

You may not be able identify a tire
with low pressure by simply looking
at it. Always use a good quality tire
pressure gauge to measure the tire's
inflation pressure. Please note that a
tire that is hot (from being driven) will
have a higher pressure measure-
ment than a tire that is cold.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1 mile (1.6 km) in that 3
hour period.
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.Information
