4. Connect the jumper cables in the exact sequence shown in the
illustration. First connect one jumper
cable to the red, positive (+) jumper
terminal of your vehicle (1).
5. Connect the other end of the jumper cable to the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
6. Connect the second jumper cable to the black, negative (-) battery/chassis
ground of the assisting vehicle (3).
7. Connect the other end of the second jumper cable to the black, negative (-)
chassis ground of your vehicle (4).
Do not allow the jumper cables to
contact anything except the correct
battery or jumper terminals or the
correct ground. Do not lean over the
battery when making connections. 8. Start the engine of the assisting
vehicle and let it run at approximately
2,000 rpm for a few minutes. Then
start your vehicle.
If your vehicle will not start after a few
attempts, it probably requires servicing.
In this event please seek qualified
assistance. If the cause of your battery
discharging is not apparent, have your
vehicle checked by an authorized
HYUNDAI dealer.
Disconnect the jumper cables in the
exact reverse order you connected them:
1. Disconnect the jumper cable from the black, negative (-) chassis ground of
your vehicle (4).
2. Disconnect the other end of the jumper cable from the black, negative
(-) battery/chassis ground of the
assisting vehicle (3).
3. Disconnect the second jumper cable from the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
4. Disconnect the other end of the jumper cable from the red, positive (+)
jumper terminal of your vehicle (1).

Emergency Situations7-6
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. Place the shift button in P (Park) and set the parking brake. If the air
conditioning is ON, turn it OFF.
3. If engine coolant is running out under the vehicle or steam is coming out
from the hood, stop the engine. Do
not open the hood until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
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.
4. Check for coolant leaking from the radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out, stop the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance.
WARNING
Your vehicle is equipped
with a pressurized coolant
reserve tank. NEVER remove
the engine coolant reservoir
tank/radiator cap or the 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 removing the engine coolant
reservoir tank/radiator cap. Wrap
a towel or thick rag around it, and
turn it counterclockwise slowly to
release some of the pressure from the
system. Step back while the pressure is
released.
When you are sure all the pressure has
been released, continue turning the cap
counterclockwise to remove it.
6. If you cannot find the cause of the overheating, wait until the engine
temperature has returned to normal.
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.
7. Proceed with caution, keeping alert for further signs of overheating. If
overheating happens again, call
an authorized HYUNDAI dealer for
assistance.
CAUTION
Serious loss of coolant indicates a
leak in the cooling system and should
be checked as soon as possible by an
authorized HYUNDAI dealer.
IF THE ENGINE OVERHEATS

Emergency Situations7-8
Tire Pressure Monitoring System
WARNING
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 control
resulting in an accident.
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
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 pressure 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 pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on
a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel
efficiency 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 maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination 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
subsequent 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 pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, 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 alternate tires and
wheels allow the TPMS to continue to
function properly.
NOTICE
If any of the below happens, have
the system checked by an authorized
HYUNDAI dealer.
1. The Low Tire Pressure TPMS Malfunction Indicator does not
illuminate for 3 seconds when the
ignition switch is placed to the ON
position or engine is running.
2. The TPMS Malfunction Indicator remains illuminated after blinking for
approximately 1 minute.
3. The Low Tire Pressure LCD display remains illuminated

7-15
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.

Emergency Situations7-16
When driving with the compact spare tire
mounted to your vehicle:
• Check the tire pressure after installing the compact spare tire. The compact
spare tire should be inflated to 60 psi
(420 kPa).
• Do not take this vehicle through an automatic car wash while the
compact spare tire is installed.
• Do not use the compact spare tire on any other vehicle because this tire
has been designed especially for your
vehicle.
• The compact spare tire’s tread life is shorter than a regular tire. Inspect
your compact spare tire regularly and
replace worn compact spare tires with
the same size and design, mounted on
the same wheel.
• Do not use more than one compact spare tire at a time.
NOTICE
When the original tire and wheel are
repaired and reinstalled on the vehicle,
the lug nut torque must be set correctly.
The correct lug nut tightening torque is
79~94 lbf·ft (11~13 kgf·m).
CAUTION
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road
conditions to avoid all hazards, such
as a potholes or debris.
• Avoid driving over obstacles. The
compact spare tire diameter is
smaller than the diameter of a
conventional tire and reduces the
ground clearance approximately 1
inch (25 mm).
• Do not use tire chains on the
compact spare tire. Because of the
smaller size, a tire chain will not fit
properly.
• Do not use the compact spare tire
on any other wheels, nor should
standard tires, snow tires, wheel
covers or trim rings be used with the
compact spare wheel.

Emergency Situations7-18
TOWING
Towing Service
ODN8079010LODN8079010L[A] : Dollies
If emergency towing is necessary,
we recommend having it done by
an authorized HYUNDAI dealer or a
commercial tow-truck service. Proper
lifting and towing procedures are
necessary to prevent damage to the
vehicle. The use of wheel dollies or
flatbed is recommended.
On 2WD vehicles, it is acceptable to
tow the vehicle with the rear wheels
on the ground (without dollies) and
the front wheels off the ground. If any
of the loaded wheels or suspension
components are damaged or the vehicle
is being towed with the front wheels on
the ground, use a towing dolly under the
front wheels.
When being towed by a commercial tow
truck and wheel dollies are not used,
the front of the vehicle should always be
lifted, not the rear.
CAUTION
• Do not tow the vehicle with the front
wheels on the ground as this may
cause damage to the vehicle.
