Jump starting can be dangerous if done
incorrectly. Follow the jump starting
procedure in this section to avoid serious
injury or damage to your vehicle. If in
doubt about how to properly jump start
your vehicle, have a service technician or
towing service do it for you.
WARNING
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 ignited.
Keep batteries out of reach of
children.
Batteries contain sulfuric 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 immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you feel
pain or a burning sensation, get medical
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.
• NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.
• The electrical ignition system works
with high voltage.
NEVER touch these components
with the vehicle running or when
the Start/Stop button is in the ON position.
• The electrical ignition system works
with high voltage. NEVER touch
these components with the (
)
indicator ON or when the START/
STOP button is in the ON position.
• Do not allow the (+) and (-) jumper
cables to touch. It may cause sparks.
• The battery may rupture or explode
when you jump start with a low or
frozen battery.
• Do not directly connect the (-) to the
jump cable. Connect the (-) to the
one of the metallic parts located far
from the jump cable in the vehicle.
The direct (-) connection to the jump
cable may cause an explosion.
• Be sure to use only 12V battery to
jump start. Using batteries with other
voltages to jump start can damage
the battery or even provoke an
explosion.

Jump starting procedure
Information
When you jump start your vehicle,
use the jumper terminal in the motor compartment.
1. Position the vehicles close enough that the jumper cables will reach, but
do not allow the vehicle body parts to
contact.
2. Avoid fans or any moving parts in the motor compartment at all times, even
when the vehicles are turned off.
3. Turn off all electrical devices such as radios, lights, air conditioning, etc.
Put the vehicles in P (Park) and set the
parking brake. Turn both vehicles OFF.
4. Open the hood.
5. Remove the battery cover located inside of the front trunk.
6. Remove the motor compartment fuse box cover.
CAUTION
Before jump starting, make sure to
correctly identify the positive (+) and
negative (-) terminals to avoid reverse
polarity connections.
ONE1081003
7. 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).
8. Connect the other end of the jumper cable to the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
9. Connect the second jumper cable to
the black, negative (-) battery/jumper
terminal of the assisting vehicle (3).
10. 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.
WARNING
Do not connect the jumper cable to
the negative (-) jumper terminal of the
discharged battery. A spark could cause
the battery to explode and lead to a
personal injury or vehicle damage.

Emergency Situations

11. Start the assisting vehicle and let
it run at approximately for a few
minutes. Then start your vehicle.
12. Keep your vehicle operating for at
least 30 minutes at idle or driving to
assure your battery receives enough
charge to be able to start on its
own after the vehicle is shut off. A
complete dead battery may require
as long as 60 minutes runtime to fully
recharge it. If vehicle is run for less,
the battery may not restart.
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).
Information
An inappropriately disposed battery can be harmful to
the environment and human health. Dispose of the battery
according to your local law(s) or
regulations.
NOTICE
To prevent damage to your vehicle: • Only use a 12-volt power supply
(battery or jumper system) to jump
start your vehicle.
• Do not attempt to jump start your
vehicle by push-starting.
• Always be sure that the battery
cover and cable are tightened after
finishing jump start your vehicle.
Otherwise is may cause damage to
the relevant parts, noise trouble, or
entrance of foreign substances.
CAUTION
While jump starting your vehicle, avoid
the positive (+) and negative (-) cables
to come in contact. A spark could cause
personal injury.

Notes on the Safe Use of the Tire
Mobility Kit
• Park your car at the side of the road
so that you can work with the Tire
Mobility Kit away from moving traffic.
• To be sure your vehicle will not move,
even when you’re on fairly level
ground, always set your parking brake.
• Only use the Tire Mobility Kit for
sealing/inflation passenger car tires.
Only punctured areas located within
the tread region of the tire can be
sealed using the tire mobility kit.
• Do not use on motorcycles, bicycles
or any other type of tires.
• When the tire and wheel are
damaged, do not use Tire Mobility Kit
for your safety.
• Use of the Tire Mobility Kit may not be
effective for tire damage larger than
approximately 4 mm (16 inch).
Contact the nearest authorized
HYUNDAI dealer if the tire cannot
be made roadworthy with the tire mobility kit.
• Do not use the Tire Mobility Kit if a tire
is severely damaged by driving run flat
or with insufficient air pressure.
• Do not remove any foreign objects
such as nails or screws that have
penetrated the tire.
• Provided the car is outdoors, leave the
vehicle running. Otherwise operating
the compressor may eventually drain
the car battery.
• Never leave the Tire Mobility Kit
unattended while it is being used.
• Do not leave the compressor running
for more than 10 minutes at a time or
it may overheat. •
Do not use the Tire Mobility Kit if the
ambient temperature is below -22°F
(-30°C).
• In case of skin contact with the
sealant, wash the area thoroughly
with plenty of water. If the irritation
persists, seek medical attention.
• In case of eye contact with the
sealant, flush your eyes for at least 15
minutes. If the irritation persists, seek
medical attention.
• In case of swallowing the sealant,
rinse the mouth and drink plenty of
water. However, never give anything
to an unconscious person and seek
medical attention immediately.

performing maintenance work: • Park your vehicle on level ground.
Shift the vehicle to P (Park), apply the
parking brake, and press the Start/
Stop button to the OFF position.
• Block the tires (front and back) to
prevent the vehicle from moving.
Remove loose clothing or jewelry
that can become entangled in
moving parts.
• Keep flames, sparks, or smoking
materials away from the battery and
motor related parts.
