Winter precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 8. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
chapter 8. The level of charge in your
battery can be checked by an authorized
HYUNDAI dealer or a service station.
Change to “winter weight” oil if
necessary
In some climates it is recommended that
a lower viscosity “winter weight” oil be
used during cold weather. See chapter
2 for recommendations. If you aren’t
sure what weight oil you should use, we
recommend that you consult with an
authorized HYUNDAI dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as described
in chapter 8 and replace them if
necessary. Also check all ignition wiring
and components to be sure they are not
cracked, worn or damaged in any way.
To keep locks from freezing
To keep the locks from freezing, squirt
an approved de-icer fluid or glycerine
into the key opening. If a lock is covered
with ice, squirt it with an approved
de-icing fluid to remove the ice. If the
lock is frozen internally, you may be able
to thaw it out by using a heated key.
Handle the heated key with care to avoid
injury.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of anti-freeze as these may damage the
paint finish.

Emergency situations
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, we strongly recommend
that you 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 engine running
or when the ignition switch 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.
• Never attempt jump start if you
observe cracks, leaks or other
damage on Battery.

Low tire pressure
telltale
Low tire pressure position
telltale and tire pressure telltale
OSU2I049054OSU2I049054
When the tire pressure monitoring
system warning indicators are
illuminated and a warning message
displayed on the cluster LCD display,
one or more of your tires is significantly
under-inflated. The low tire pressure
position telltale light will indicate which
tire is significantly under-inflated by
illuminating the corresponding position
light.
If either telltale illuminates, immediately
reduce your speed, avoid hard cornering
and anticipate increased stopping
distances. You should stop and check
your tires as soon as possible. Inflate
the tires to the proper pressure as
indicated on the vehicle’s placard or tire
inflation pressure label located on the
driver’s side center 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 a
spare tire.
If you drive the vehicle for about 10
minutes at speeds above 25 km/h after
replacing the low pressure tire with the
spare tire, the following will happen:
• The TPMS malfunction indicator may
blink for approximately 1 minute and
then remain continuously illuminated
because the TPMS sensor is not
mounted on the spare wheel.
NOTICE
In winter or cold weather, the low tire
pressure telltale may be illuminated if
the tire pressure was adjusted to the
recommended tire inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning because
the decreased temperature leads to a
proportional lowering of tire pressure.
When you drive your vehicle from a
warm area to a cold area or from a cold
area to a warm area, or the outside
temperature is greatly higher or lower,
you should check the tire inflation
pressure and adjust the tires to the
recommended tire inflation pressure.
WARNING
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 pressure tires
can cause the tires to overheat and fail.

9-12
Emergency situations
TPMS (Tire Pressure
Monitoring System)
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. If the system is able
to correctly detect an under inflation
warning at the same time as system
failure then it will illuminate the TPMS
malfunction indicator.
We recommend that the system be
checked by an authorized HYUNDAI
dealer.
NOTICE
If there is a malfunction with the TPMS,
the low tire pressure position telltale
will not be displayed even though the
vehicle has an under-inflated tire.
CAUTION
• The TPMS malfunction indicator
may be illuminated if the vehicle is
moving around electric power supply
cables or radios transmitter such as
at police stations, government and
public offices, broadcasting stations,
military installations, airports, or
transmitting towers, etc. This can
interfere with normal operation of
the Tire Pressure Monitoring System
(TPMS).
• The TPMS malfunction indicator may
illuminate if snow chains or some
separately purchased devices such
as notebook computers, mobile
charger, remote starter, navigation
etc. are used in the vehicle. This can
interfere with normal operation of
the Tire Pressure Monitoring System
(TPMS).
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure will come on. We recommend
that the flat tire be checked by an
authorized HYUNDAI dealer.
NOTICE
We recommend that you use a
puncture-repairing agent approved by
HYUNDAI.
The sealant on the tire pressure sensor
and wheel shall be eleminated when
you replace the tire with a new one.
Each wheel is equipped with a tire
pressure sensor mounted inside
the tire behind the valve stem. You
must use TPMS specific wheels. It is
recommended that you have your tires
serviced by an authorized HYUNDAI
dealer.
Even if you replace the low pressure tire
with the spare tire, the Low Tire Pressure
Telltale will blink or remain on until the
low pressure tire is repaired and placed
on the vehicle.
After you replace the low pressure tire
with the spare tire, the Low Tire Pressure
Telltale may blink or illuminate after a
few minutes because the TPMS sensor
mounted on the spare wheel is not
initiated.
Once the low pressure tire is re-inflated
to the recommended pressure and
installed on the vehicle or the new TPMS
sensor mounted on the wheel, the TPMS
malfunction indicator and the low tire
pressure and position telltales will turn
off within a few minutes of driving.
If the indicator does not turn off after a
few minutes of driving, we recommend
that the system be checked by an
authorized HYUNDAI dealer.

9-13
09
NOTICE
If original mounted tire is replaced
with the spare tire, the TPMS sensor
on the replaced spare wheel should be
initiated and we recommend that the
TPMS sensor on the original mounted
wheel be deactivated by a HYUNDAI
dealer. If the TPMS sensor on the
original mounted wheel located in the
spare tire carrier still activates, the
tire pressure monitoring system may
not operate properly. We recommend
that the system be serviced by an
authorized HYUNDAI dealer.
You may not be able to identify a low
tire 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
measurement than a tire that is cold.
A cold tire means the vehicle is in parked
position for at least 3 hours or driven
less than 1.6 km (1 mile) in that period.
Allow the tire to cool before measuring
the inflation pressure. Always be sure
the tire is cold before inflating to the
recommended pressure.
NOTICE
We recommend that you use the tire
sealant approved by HYUNDAI if your
vehicle is equipped with a Tire Pressure
Monitoring System. The liquid sealant
can damage the tire pressure sensors.
WARNING
TPMS
• The TPMS cannot alert you to severe
and sudden tire damage caused by
external factors such as nails or road
debris.
• If you feel any vehicle instability,
immediately take your foot off
the accelerator, apply the brakes
gradually and with light force, and
slowly move to a safe position off the
road.
WARNING
Protecting TPMS
Tampering with, modifying, or disabling
the Tire Pressure Monitoring System
(TPMS) components may interfere with
the system’s ability to warn the driver
of low tire pressure conditions and/
or TPMS malfunctions. Tamper-ing
with, modifying, or disabling the Tire
Pressure Monitoring System (TPMS)
components may void the war-ranty for
that portion of the vehicle.

Changing tires
WARNING
A vehicle can slip or roll off of a jack
causing serious injury or death to you
or those nearby. Take the following
safety precautions:
• Do not get 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 provided 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 support.
• 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.Follow these steps to change your
vehicle’s tire:
1. Park on a level, firm surface.
2. Move the shift lever into N (Neutral,
for Automated manual transmission
vehicle) or neutral (for manual
transmission vehicle), apply the
parking brake, and place the ignition
switch in the LOCK/OFF position.
3. Press the hazard warning flasher
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.

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.
i Information
Check the tire pressure as soon as possible
after installing a spare tire. Adjust it to
the recommended pressure.
NOTICE
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. We recommend that you 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
emergency 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 80
km/h (50 mph).
• 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.
